Heat the olive oil in a large saucepan over medium heat. Add the diced red onion and sauté for about 5 minutes, until soft and translucent.
2 Tablespoons Olive oil, 1 Large Red onion
Stir in the minced garlic and cook for another minute, just until fragrant. Add the diced carrot and cook for 2–3 minutes, allowing it to soften slightly.
3 Teaspoons Minced garlic, 1 Carrot
Sprinkle in the oregano, Italian seasoning, sugar, salt, black pepper, and chili flakes. Stir well and let the spices toast for about 30 seconds to release their flavor.
2 Tablespoons Dried oregano, 2 Tablespoons Italian seasoning, 1 Teaspoon sugar, 1/2 Teaspoon Salt, 1/2 Teaspoon Ground black pepper, 1/4 Teaspoon Chili flakes
Add the canned plum tomatoes, breaking them up gently with a spoon as you pour them into the pan. Stir in the tomato puree and water, then mix everything together.
Bring the sauce to a gentle simmer and let it cook uncovered for 15–20 minutes, stirring occasionally, until the sauce thickens slightly.
Once cooked, use an immersion blender to blend the sauce directly in the pan until smooth. If you don’t have one, carefully transfer the sauce to a blender and blend until it reaches your preferred consistency.
Taste the sauce and adjust the seasoning to your liking—add more chili flakes for extra heat, or a pinch more salt and pepper if needed.
Your spicy pizza sauce is ready to use! Spread it over pizza dough, stir into pasta, or store it for later use.
Notes
Tips and Tricks
Texture matters: If you like a chunkier sauce, blend only half of it and stir it back into the pan.
Make ahead: This sauce can be made in advance and stored in the fridge for up to 5 days, or frozen for up to 3 months.
Boost the flavor: Add a splash of red wine or balsamic vinegar while simmering for extra depth.
Spice it up: Prefer a fiery kick? Double the chili flakes or add a diced fresh chili.
Use quality tomatoes: Good canned plum tomatoes make a big difference in flavor and richness.
