What is Tofu?

Tofu, also called bean curd, is a soy food made by coagulating soy milk and forming the resulting curds into blocks. Its texture can range from delicate and custard-like to dense and firm, which makes tofu suitable for everything from soups and stir-fries to sauces, smoothies, and desserts.

Although tofu is often described in the United States as a meat substitute, it is much more than that. It has been an important ingredient in Chinese cooking for centuries and is now used in many East and Southeast Asian cuisines, with different regions developing their own tofu styles, dishes, and preparation methods.

This guide explains what tofu is made from, how the different types compare, what it tastes like, how to store it, and how to choose the right tofu for your recipe.

Tofu at a Glance

What Is Tofu Made From?

Traditional tofu is made from three basic components:

1. Soybeans
2. Water
3. A coagulant

The process typically begins by soaking dried soybeans and grinding them with water. Depending on the production method, the resulting mixture may be cooked before or after it is strained to produce soy milk. A coagulant is then added, causing the soy proteins to form curds or a continuous gel.

Common tofu coagulants include calcium sulfate and magnesium salts such as magnesium chloride. Nigari is a traditional seawater-derived coagulant composed mainly of magnesium salts, particularly magnesium chloride. The coagulant used can affect the tofu's texture, yield, flavor, and mineral content.

For most block tofu, the curds are transferred to a mold and pressed to remove some of their liquid. Removing more water generally produces a firmer, denser block. Silken tofu is produced differently because the soy milk is allowed to set into a smooth, continuous gel without the curds being cut and pressed in the same way.

Tofu-making is sometimes compared with cheesemaking because both processes involve coagulation. Plain tofu does not contain dairy, however, and it is not cheese.

Is Tofu Fermented?

Standard tofu varieties, including silken, soft, medium, firm, and extra-firm tofu, are not fermented. They are made by coagulating soy milk.

Fermented bean curd, sometimes called preserved tofu or furu, is a separate product. It is commonly aged and preserved in a seasoned brine and has a salty, concentrated flavor that is sometimes compared with strong cheese. It is usually used in small amounts as a condiment or seasoning.

Other fermented tofu products also exist, so “fermented tofu” does not always refer to one particular production method, flavor, or texture. Tofu, fermented bean curd, and tempeh are all made from soybeans, but they are produced and used differently.

What Does Tofu Taste Like?

Plain tofu has a mild flavor that may be described as slightly nutty or gently beany. Fresh tofu can have a more noticeable soybean flavor, while some packaged products taste very neutral.

Texture makes as much difference as flavor. Silken tofu is smooth and custard-like. Firm tofu is tender but holds its shape, while extra-firm tofu is denser and chewier.

Because tofu has a mild flavor, seasoning its surface and cooking it until browned can make a noticeable difference. Cutting it into smaller pieces also creates more surface area for marinades, sauces, spices, and crisp edges.

Strong sauces are not the only way to enjoy tofu. In many traditional dishes, fresh tofu is served simply so its delicate texture and subtle soybean flavor remain part of the experience.

Types of Tofu and How to Use Them

Tofu labels are not completely standardized, and one brand's firm tofu may feel similar to another brand's extra-firm tofu. Treat the descriptions on the package as a guide, then adjust based on the texture you find after opening it.

Silken tofu is set with a high moisture content and remains much more delicate than ordinary block tofu. Medium tofu is tender enough for stews and braises, while extra-firm tofu is pressed more heavily and is better suited to methods where the pieces need to remain intact.

Silken Tofu

Silken tofu is smooth, soft, and easily broken. It may be sold in refrigerated containers or in shelf-stable cartons.

Its creamy consistency works well in:

• blended sauces and dressings;
• smoothies;
• chocolate mousse and other tofu desserts;
• creamy soups;
• dips;
• gentle savory dishes;
• desserts that need a smooth filling.

Do not place silken tofu in a tofu press. Its structure is too delicate, and pressing it will crush it rather than improve it.

Soft and Medium Tofu

Soft and medium tofu retain more water than firm varieties. They work particularly well in dishes where a tender texture is desirable, including soups, stews, braises, and tofu scrambles.

Handle these varieties carefully when cutting or turning them. A wide spatula or spoon can help keep the pieces intact.

Firm Tofu

Firm tofu is one of the most versatile choices for everyday cooking. It is sturdy enough to cube or slice but remains softer inside than extra-firm tofu.

Use it in curries, stir-fries, noodle dishes, rice bowls, and baked tofu recipes. Pressing may help when you want more browning, although it is not necessary for every dish.

Extra-Firm and Super-Firm Tofu

Extra-firm and super-firm tofu contain less water and are easier to cook without breaking apart. They are the most practical choices for crisp tofu, grilling, skewers, sandwiches, and dishes where you want a dense, chewy texture.

Some super-firm tofu is sold vacuum-packed with very little loose water. This type may only need to be patted dry rather than pressed.

Is Tofu Healthy?

Tofu provides soy protein, and soy is considered a complete protein because it contains all nine essential amino acids that must be obtained from food. Tofu may also provide iron, calcium, magnesium, and other nutrients, but the amounts vary considerably among products.

Firmness alone does not tell you exactly how nutritious a tofu product will be. The soybean concentration, serving size, coagulant, added ingredients, and amount of water all affect its nutrition.

Calcium is a good example. Tofu made with calcium sulfate may contain considerably more calcium than tofu produced with a different coagulant. The most reliable way to evaluate a particular product is to read its Nutrition Facts label and ingredient list.

USDA FoodData Central contains entries for numerous generic and branded tofu products, illustrating how much the nutrient values can vary from one type to another.

For a more detailed breakdown, see our tofu nutrition guide.

Tofu does not guarantee weight loss or treat health conditions, but it can be one nutritious protein option within a varied diet. Harvard's Nutrition Source notes that research on soy is sometimes presented in conflicting ways, but whole soy foods such as tofu can be included regularly as part of a balanced eating pattern.

Tofu and Soy Allergies

Tofu is made from soybeans. The FDA lists soybeans among the nine major food allergens recognized in the United States.

Anyone with a diagnosed soy allergy should avoid tofu and read the full ingredient and allergen information on packaged foods. Flavored tofu may also contain other allergens, including wheat or sesame, depending on its seasoning.

Where Did Tofu Originate?

Tofu originated in China, but the exact date and circumstances of its invention are uncertain.

Its invention is traditionally attributed to Liu An, Prince of Huainan, who lived from 179 to 122 BC. Historians have not found conclusive evidence that he personally invented tofu. Another origin theory proposes that mineral-rich salt accidentally coagulated a cooked soybean mixture, but this also remains a theory rather than an established historical event.

The earliest surviving written use of the term “doufu” commonly identified by tofu historians appears in the Ch'ing I Lu, written by T'ao Ku around 950 AD. Because this record is much later than the traditional Han dynasty origin story, it is most accurate to say that tofu has ancient Chinese roots but no securely documented single inventor.

From China, tofu became established in many other East and Southeast Asian food cultures. Today it appears in numerous forms, including silken tofu, pressed tofu, fried tofu, tofu skin, fermented bean curd, tofu puffs, and regional specialties that can be very different from the refrigerated blocks familiar to many American shoppers.

In a letter to John Bartram dated January 11, 1770, Benjamin Franklin enclosed beans from China and relayed an account of a cheese-like food called “Tau-fu.” Although Franklin's account did not fully describe tofu production as it is understood today, the letter remains an important early American reference to tofu.

How to Choose Tofu at the Store

The best tofu is not automatically the firmest, most expensive, organic, or non-GMO option. The best choice is the product that suits your recipe, dietary needs, and flavor preferences.

Choose the Firmness for the Dish

Use silken tofu when you want a smooth result. Choose firm or extra-firm tofu when the pieces need to hold their shape.

A recipe written for silken tofu may fail with extra-firm tofu, and the reverse is also true. The firmness is part of the recipe, not simply a matter of preference.

Read the Ingredient List

Plain tofu generally has a short ingredient list containing soybeans or soy milk, water, and one or more coagulants.

Calcium sulfate may increase the calcium content. Magnesium chloride or nigari can produce a different texture. Neither automatically means that one tofu is better than another.

Flavored, smoked, baked, or marinated tofu may contain oil, salt, sugar, wheat, sesame, or other seasonings. Check both the ingredient list and Nutrition Facts label when these details matter.

Check the Package

Do not buy refrigerated tofu if the package is leaking, damaged, or unusually swollen. Keep refrigerated tofu cold and follow the storage instructions printed on the container.

Shelf-stable tofu does not need refrigeration before opening, but it should still be stored as directed and used by the date on the package.

How to Store Tofu

Unopened Tofu

Keep refrigerated tofu in the refrigerator and follow the storage directions printed on the package. Check whether the printed date is described as a best-by, use-by, or other type of date rather than assuming that every package date has the same meaning.

Shelf-stable tofu can remain in a cool pantry before opening when the package is undamaged, and the manufacturer's directions allow room-temperature storage.

Opened Tofu

After opening water-packed tofu, transfer any unused portion to a clean container, cover it with fresh water, and refrigerate it below 40°F. Oregon State University Extension recommends using opened tofu within three to four days.

Discard tofu if it:

• develops a sour or unpleasant odor;
• becomes slimy;
• changes color unexpectedly;
• shows mold;
• comes from a swollen or leaking package.

Do not taste questionable tofu to decide whether it is safe to use.

Can You Freeze Tofu?

Yes. Water-packed tofu can be frozen when it has been handled and refrigerated properly, although freezing changes its texture.

As the water inside tofu freezes, ice crystals widen spaces within its protein structure. After thawing, the tofu usually has a more open, porous, spongy, and chewy texture. Some cooks prefer this texture, while others prefer fresh tofu.

Frozen and thawed tofu works particularly well in curries, stir-fries, braised dishes, soups, and other recipes where its porous structure can hold cooking liquid. Thaw it safely in the refrigerator, then gently squeeze or press out excess water before cooking.

Do You Need to Press Tofu?

Pressing removes some of the water held inside block tofu. It can help firm or extra-firm tofu brown more readily and may produce a denser texture.

Pressing is useful when:

• you want crisp edges;
• the tofu is packed in a large amount of water;
• the recipe specifically calls for pressed tofu;
• you want a firm texture for grilling or frying.

Pressing is not always necessary. Skip it when:

• using silken tofu;
• making a soup or stew where a tender texture is desirable;
• using vacuum-packed super-firm tofu with very little moisture;
• the recipe depends on soft, juicy tofu.

A tofu press is convenient, but it is not essential. You can place the tofu between clean kitchen towels or paper towels, set a plate on top, and add a moderate weight. Avoid using so much weight that the block cracks or collapses.

How to Cook Tofu for Better Flavor and Texture

The right method depends on the tofu and the result you want, but a few principles apply to most crisp tofu recipes.

1. Start With the Right Type

Use firm, extra-firm, or super-firm tofu when the pieces need to brown and remain intact.

Save silken tofu for recipes that need its smooth, delicate consistency.

2. Remove Surface Moisture

Drain the tofu and pat it dry. Press it when appropriate.

A dry surface browns more effectively than a wet one. This is particularly important when pan-frying, baking, grilling, or air-frying tofu.

3. Cut It Evenly

Cut the tofu into evenly sized cubes, slabs, triangles, or sticks so the pieces cook at approximately the same rate.

Smaller pieces provide more surface area for seasoning and browning. Larger slabs retain a softer center.

4. Season It Properly

Tofu's mild flavor allows it to work with many seasonings, but it still needs enough salt, spice, sauce, or marinade to taste balanced.

Try flavors such as:

• soy sauce or tamari;
• garlic and ginger;
• chile sauce;
• curry spices;
• sesame;
• citrus;
• miso;
• barbecue sauce;
• herbs and spice blends.

5. Give It Space

Arrange tofu in a single layer when baking, frying, or air-frying. Crowded pieces trap steam, which makes browning more difficult.

Turn the pieces as needed so more than one side has contact with the hot pan or cooking surface.

6. Add Wet Sauce at the Right Time

A liquid-heavy sauce can soften a crisp coating. For better contrast, brown the tofu first and add the sauce near the end, unless the recipe is intended to be braised or simmered.

Easy Ways to Use Tofu

Tofu can be used as the main ingredient in a dish or as one component of a larger meal.

Pan-Fry It

Slice or cube firm tofu, dry it well, season it, and cook it in a lightly oiled skillet until browned. Finish it with a sauce or serve it over rice or noodles.

Bake or Air-Fry It

Extra-firm tofu works well for baking and air-frying because it holds its shape. Spread the pieces apart so hot air can circulate around them.

Add It to Stir-Fries

Brown the tofu separately before adding watery vegetables or sauce. This helps it retain more texture in the finished dish.

Simmer It in Soups and Curries

Soft, medium, or firm tofu can be added to broths, curries, and stews. Stir gently to prevent delicate pieces from breaking.

Crumble It

Crumble firm or medium tofu into a skillet for tofu scramble, taco fillings, pasta sauces, or seasoned bowls.

Blend Silken Tofu

Silken tofu can add body to dips, dressings, sauces, soups, smoothies, and desserts without leaving pieces of tofu in the finished dish.

Common Tofu Mistakes

Using the Wrong Type

Silken tofu cannot usually replace extra-firm tofu in a stir-fry, and extra-firm tofu will not produce the same smooth result in a mousse or creamy sauce.

Check the recipe before shopping.

Pressing Silken Tofu

Silken tofu is not designed to be pressed. Drain it carefully and scoop or slice it as directed.

Cooking Tofu While It Is Still Wet

Excess water on the outside of tofu encourages steaming rather than browning. Pat the surface dry before using a high-heat cooking method.

Crowding the Pan

Too many pieces lower the pan's temperature and trap moisture. Cook in batches when necessary.

Adding Too Much Sauce Too Early

Sauce can prevent the surface from browning or soften tofu that was already crisp. Brown the tofu first when crispness is the goal.

Expecting Tofu to Taste Like Meat

Tofu has its own flavor and texture. It can replace meat in the structure of some meals, but the best results usually come from choosing a cooking method that suits tofu rather than expecting it to imitate another ingredient exactly.

Frequently Asked Questions

Is tofu vegan?

Plain tofu is made from soybeans, water, and a coagulant, so it is plant-based. Check the label on flavored or prepared tofu because additional ingredients vary.

Is tofu gluten-free?

Plain, unflavored tofu is generally gluten-free. Flavored tofu, marinades, sauces, and prepared tofu dishes may contain wheat or other sources of gluten, so check the ingredient and allergen information.

Does tofu need to be cooked?

Not always. Many packaged tofu products can be served cold or heated, although cooking can improve their flavor and texture. Always follow the storage and preparation directions on the package.

What is the best tofu for beginners?

Extra-firm tofu is often the easiest place to start because it is sturdy, simple to cut, and suitable for baking, pan-frying, air-frying, and stir-fries. Silken tofu is the better choice when making a blended sauce, dip, smoothie, or dessert.

What is the difference between tofu and tempeh?

Tofu is made by coagulating soy milk. Tempeh is made by fermenting cooked soybeans into a firm cake. Tempeh has a stronger, nuttier flavor and a denser, more textured consistency.

Can tofu be frozen?

Yes, but freezing makes tofu more porous, spongy, and chewy. This can be useful in curries, stir-fries, and saucy dishes, but it will not have the same texture as fresh tofu.

How do you make tofu crispy?

Choose firm or extra-firm tofu, remove excess surface moisture, cut it evenly, and cook it in a single layer. Avoid adding a large amount of wet sauce until the tofu has browned.

Ready to Cook With Tofu?

The most important step when cooking tofu is choosing the right variety. Use silken tofu when you need a smooth, delicate texture, and choose firm or extra-firm tofu when you want pieces that can be browned, baked, fried, or grilled.

Once you understand that difference, tofu becomes much easier to use. Start with one simple cooking method, season it well, and pair it with a sauce or dish you already enjoy.
