There are several good substitutes for tomato paste that can be used depending on the recipe and what is available:
- Tomato sauce or tomato purée: Use 2-3 times the amount of tomato purée or sauce to replace tomato paste. Add a bit of sugar and reduce other liquids for balance.
- Ketchup: Can be used 1:1 as a substitute, but it is sweeter and tangier.
- Fresh or canned tomatoes: Cook down fresh (about 4-5 times more) or canned tomatoes (about 3 times more) until thickened to substitute.
- Tomato passata: Use about 3 tablespoons of passata per tablespoon of tomato paste. It can be reduced by simmering for thicker consistency.
- Marinara sauce: Substitute 1:1, keeping in mind added herbs and flavors.
- Harissa or pureed roasted red peppers: Adds a smoky or spicy twist but has different flavors.
- Olive tapenade or soy sauce: For non-tomato alternatives to add depth and umami.
Other thickening agents like cornstarch with sugar, or even small amounts of sugar for sweetness can complement these substitutes depending on the role of tomato paste in the dish. Adjust quantities and cooking times to achieve the desired flavor and consistency.
