This is the everyday tomato sauce for pasta, pizza and meatballs: canned tomatoes, olive oil, garlic, butter for roundness and 40 minutes of gentle simmering. It is simple, and the quality of the tomatoes matters most.

Method

  1. Tip the tomatoes into a bowl and crush them with your hands or a potato masher into rough pieces. Swirl 100 ml water in each can and add that too.
  2. Heat the olive oil in a wide pan over medium-low heat. Add the garlic and chili and cook gently until the garlic is pale gold and fragrant, 1–2 minutes. Do not let it brown.
  3. Add the tomatoes and the salt and bring to a simmer.
  4. Simmer uncovered over low heat, stirring every 10 minutes, for 35–40 minutes, until thickened, glossy and the oil starts to pool at the edges.
  5. Stir in the butter and basil sprig, then remove the basil after 5 minutes. Taste and adjust the salt. If the tomatoes are very sharp, a pinch of sugar helps.
  6. For a smooth sauce, blend briefly with a stick blender.

Why it works

Canned tomatoes are picked ripe and cooked once, so they are more reliable than off-season fresh ones. Simmering evaporates water and concentrates sugars and glutamates, while the acidity softens. Butter and olive oil carry the fat-soluble aromas of tomato and round off the acidity, giving a silky finish.

Common mistakes

  • Burning the garlic: the whole sauce turns bitter. Keep the heat low and add the tomatoes as soon as it's gold.
  • Using a narrow, deep pot: the sauce takes twice as long to reduce. Use a wide pan.
  • Covering the pan: the water can't escape and the sauce stays thin.

Variations

Marinara-style quick sauce
Simmer just 15 minutes with plenty of garlic and oregano for a brighter, looser sauce.
Pizza sauce
Don't cook it: blend 1 can tomatoes with 1 tbsp olive oil, 1 small garlic clove and 3 g salt; use on Pizza Margherita.

Make ahead and storage

Keeps 5 days in the fridge and 6 months frozen. Make a double batch.

Notes

Whole canned tomatoes are usually better quality than crushed or chopped. For the dairy-free version, use 1 extra tbsp olive oil instead of butter.
