This classic marinara sauce is a versatile staple that every home cook should have in their repertoire. By gently caramelising onions and garlic in olive oil before simmering high-quality tinned tomatoes, you create a rich, vibrant base that far surpasses any shop-bought alternative. Fresh basil adds a sweet, peppery aroma, making this vegan-friendly sauce the perfect companion for spaghetti, homemade pizzas, or as a base for more complex Mediterranean dishes.

Preparing a large batch of this savoury sauce is an excellent way to meal prep for the week ahead. It freezes beautifully, ensuring you always have a healthy, homemade option ready for a quick weeknight dinner. Simply toss it with your favourite pasta shape or use it as a dipping sauce for crusty bread to enjoy its deep, authentic Italian-inspired flavour.

Heat oil in a medium heavy pot over medium. Cook onion, stirring occasionally, until very soft, 8–10 minutes.

Reduce heat; simmer gently, stirring occasionally, until sauce is thick, about 1 hour. Season with salt and pepper. Let cool.
