Tomato Sauce

This classic homemade tomato sauce is a versatile staple for any kitchen, offering a bright and robust flavour that shop-bought versions simply cannot match. By slowly simmering fresh plum tomatoes with fragrant garlic and onions, you create a rich, savoury base that celebrates simple, high-quality ingredients. The addition of fresh basil at the end provides a peppery sweetness that lifts the entire dish.

As a naturally vegan recipe, this sauce is a healthy and heart-friendly choice for a variety of family meals. It works perfectly tossed through spaghetti, spread over a sourdough pizza base, or used as a foundation for a vegetable-packed ratatouille. You can easily adapt the texture by using tinned plum tomatoes or adding a spoonful of tomato purée for a deeper, more concentrated finish.

Ingredients for Tomato Sauce

  • 3 tablespoons olive oil

  • 2 yellow onions, finely diced

  • 8 cloves garlic, minced

  • 1.1kg plum (Roma) tomatoes, peeled, seeded, and chopped

  • 1 tablespoon chopped fresh basil

  • Salt and freshly ground pepper

How to make Tomato Sauce

Heat the olive oil in a large saucepan over medium-high heat. Add the onions and sauté until translucent, about 6 minutes. Add the garlic and sauté until fragrant, about 1 minute. Add the tomatoes, bring the sauce to a boil, reduce the heat, and simmer for 20-25 minutes. Add the basil and simmer for 5 minutes more. Taste and season with salt and pepper.

Replace the fresh tomatoes with whole canned tomatoes that have been seeded and coarsely chopped. (Reserve the juices to add to the pot as well.) Be sure to taste the tomatoes before starting the sauce. If the tomatoes need extra body or flavour, sauté 40 to 50g tomato paste with the onions after the onions are translucent. Or replace half of the whole tomatoes with tomato purée.
