Ingredients

  • 800 g ripe tomatoes, chopped
  • 2 tbsp olive oil
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 1 tsp salt
  • 1 tsp sugar
  • 1 tsp dried oregano
  • 1/2 tsp black pepper
  • Fresh basil leaves, to taste

Steps

  1. Heat the olive oil in a large saucepan over medium heat for about 2 minutes until shimmering.

  2. Add the chopped onions and sauté for 5 minutes until they become translucent and slightly golden.

  3. Stir in the minced garlic and cook for an additional 1 minute, just until fragrant.

  4. Add the chopped tomatoes, salt, sugar, oregano, and black pepper. Bring to a simmer, then reduce the heat to low.

  5. Simmer uncovered for about 10 minutes, stirring occasionally, until the tomatoes break down and the sauce thickens.

  6. Remove from heat and blend the mixture until smooth, adding fresh basil leaves for flavor. If the sauce seems too thick, add a splash of water to reach desired consistency.

Why this works

This tomato passata base recipe relies on the classic technique of sautéing to build flavor. Heating the olive oil first allows the onions to soften and release their natural sugars, which enhances the overall sweetness of the sauce. The addition of garlic near the end of the onion cooking time ensures that it doesn't burn, maintaining its aromatic qualities. Simmering the mixture allows the tomatoes to break down; this is crucial for developing a rich, deep flavor. If the sauce seems too thick, adding a splash of water helps achieve the desired consistency without sacrificing flavor. Additionally, incorporating fresh basil at the end preserves its fresh aroma, elevating the sauce's overall taste profile. If the sauce ends up too acidic due to overripe tomatoes, a pinch of sugar can balance this out effectively.
