How to Make Tomato Basil Sauce

Wash the tomatoes thoroughly, chop them, and place them into a heavy-bottomed pot. Pour in about half a cup (120 ml) of water. Overripe and even cracked tomatoes are wonderful for this sauce, as long as they show no signs of spoilage.

Use the ripest, juiciest tomatoes you can find to give the sauce a rich, concentrated flavor.

Cover the pot with a lid and cook the tomatoes over high heat for 15 minutes after they come to a boil. They should break down into a thick tomato mash with no whole pieces remaining. The exact cooking time will depend on the variety of tomatoes and the size of the chunks.

Set a fine-mesh sieve over a deep bowl and transfer the cooked tomatoes into it to remove the skins and seeds.

Press the tomatoes through the sieve using a tablespoon, squeezing thoroughly to extract all the juices, and scrape the rich pulp from the underside of the mesh.

Dice the yellow onion as finely as possible and slice the garlic cloves paper-thin. Pour the olive oil into a skillet, add the onion and garlic, and sauté slowly over low heat until the onion turns nearly translucent.

Sprinkle in two teaspoons of dried thyme and sauté the onion with the spices for a few more minutes. The aroma at this stage is simply incredible—this is exactly how a great tomato sauce should smell.

Stir in the fragrant sweet paprika and dried garlic. While dried garlic is optional, its aroma differs slightly from fresh garlic and brings a unique, savory note to the sauce’s bouquet. Season with salt and sugar to taste.

Sweet paprika and dried garlic bring warm, savory undertones to the fresh tomatoes.

Bring the sauce to a boil, then reduce to medium heat and simmer for 10 minutes. Meanwhile, pluck the fresh green basil leaves from their stems, roll the larger leaves into tight cigars, and slice them into thin ribbons (chiffonade). Stir the chopped basil into the sauce 2 minutes before taking it off the heat.

Taste the finished sauce and adjust the balance of sweetness and acidity as needed. For instance, if your tomatoes are naturally tart, add a pinch more sugar.

Boil some spaghetti, warm up the tomato basil sauce in a pan, and toss the cooked pasta directly into the sauce with a knob of butter. Heat everything together for a couple of minutes, shower with grated Parmesan, and enjoy!

If you feel like experimenting, try tossing a few capers or finely chopped olives into the sauce to give it an even more pronounced Mediterranean character. This sauce also freezes beautifully: simply portion it into small containers for a quick, flavorful weeknight dinner. Remember to always add the fresh basil at the very end of cooking so it retains its vibrant green color and precious essential oils, which make this dish truly special.
