Heat the olive oil in a large saucepan over medium heat. Add the diced red onion and cook for about 5 minutes until soft and translucent.
2 tablespoons olive oil, 1 large red onion
Stir in the minced garlic and cook for 1 minute until fragrant. Add the diced carrot and cook for 2-3 minutes until slightly softened.
3 Teaspoons minced garlic, 1 carrot
Sprinkle in the oregano, Italian seasoning, sugar, salt, and black pepper, stirring for about 30 seconds to release the flavors.
2 tablespoons dried oregano, 2 tablespoons Italian seasoning, 1 teaspoon granulated sugar, 1/2 teaspoon Salt, 1/2 teaspoon ground black pepper
Pour in the canned plum tomatoes, breaking them up gently with a spoon. Add the tomato puree and water, then mix everything together.
800 Grams plum tomatoes, 2 tablespoons tomato puree, 250 ml water
Bring the sauce to a gentle simmer and cook uncovered for 15-20 minutes, stirring occasionally, until it thickens slightly.
Use an immersion blender to puree the sauce directly in the pan, or carefully transfer to a blender and blend until smooth. Taste and adjust seasoning with extra salt, or pepper if desired.
Your pasta or pizza sauce is ready! Use it immediately, stir into pasta, spread on pizza dough, or store in an airtight container in the fridge for up to 5 days.
Notes
Tips and Tricks
Dice the onion and carrot uniformly so they cook evenly.
For a chunkier sauce, blend only half the tomatoes and leave the rest chunky.
Add a splash of balsamic vinegar or smoked paprika for extra depth of flavor.
The sauce keeps in the fridge for up to 5 days and can be frozen for 2-3 months.
Add crushed red pepper or fresh chili for a spicy kick.
For a thicker sauce, simmer a few minutes longer; for a thinner sauce, add a splash more water.
