What Is Tomato Paste Used For? A Culinary Essential Explained
Tomato paste is primarily used to intensify the tomato flavor in dishes, add richness and depth, and act as a thickening agent. Its concentrated nature makes it a versatile ingredient in various cuisines.
A Brief History and Background of Tomato Paste
Tomato paste, in essence, is cooked-down tomatoes with the skin and seeds removed. The process of concentrating tomatoes has been around for centuries, originating in regions with warm climates and abundant tomato harvests, like Italy. The goal was simple: to preserve the summer’s bounty for year-round use. Before modern canning techniques, this was crucial for sustaining families through lean seasons. Over time, variations in production techniques and regional preferences have led to different types of tomato paste found today, each offering its unique flavor profile and application.
The Benefits of Using Tomato Paste
Beyond just flavor, tomato paste offers a range of benefits in cooking:
- Intensified Tomato Flavor: This is its primary function. A small amount can dramatically boost the tomato taste of a dish.
- Richness and Depth: The concentrated sugars in tomato paste caramelize during cooking, adding a layer of complexity to the flavor profile.
- Thickening Agent: Tomato paste naturally thickens sauces, soups, and stews without the need for flour or cornstarch.
- Umami Boost: Tomato paste is naturally rich in glutamates, providing a savory, umami flavor that enhances the overall taste of the dish.
- Preservation and Shelf Life: Tomato paste has a long shelf life, especially when stored properly in an airtight container in the refrigerator after opening.
The Process of Making Tomato Paste
While you can buy it readily in stores, understanding the process of making tomato paste gives you insight into its concentrated flavor:
- Tomato Selection: Ripe, juicy tomatoes are essential. Roma tomatoes are often preferred.
- Preparation: Tomatoes are washed, cored, and chopped.
- Cooking: The tomatoes are cooked down slowly, often for several hours, to reduce the water content.
- Straining: The cooked tomatoes are strained to remove the skins and seeds, resulting in a smooth puree.
- Concentration: The puree is cooked further, often for several more hours, until it reaches a thick, concentrated consistency.
- Packaging: The finished paste is cooled and packaged into tubes, cans, or jars.
Common Mistakes When Using Tomato Paste
Using tomato paste correctly is key to reaping its benefits. Here are some common mistakes to avoid:
- Not Cooking It First: Raw tomato paste can taste metallic and acidic. Always cook it briefly in oil or butter before adding other ingredients. This caramelizes the sugars and mellows the acidity.
- Using Too Much: A little goes a long way. Overuse can lead to an overly strong tomato flavor that overpowers other ingredients.
- Not Storing It Properly: Once opened, tomato paste is prone to mold. Store it in an airtight container in the refrigerator, or freeze it in small portions.
- Adding It Too Late: For maximum flavor impact, add tomato paste early in the cooking process so it has time to develop its flavors.
Tomato Paste vs. Tomato Puree vs. Tomato Sauce
It’s easy to confuse tomato paste with other tomato-based products. Here’s a quick comparison:
| Product | Consistency | Flavor | Usage |
|---|---|---|---|
| Tomato Paste | Thick | Intense, concentrated tomato flavor | Flavoring, thickening, adding richness |
| Tomato Puree | Smooth | Mild, less concentrated tomato flavor | Base for sauces, soups, and stews |
| Tomato Sauce | Thin | Seasoned tomato flavor | Ready-to-use sauce for pasta, pizzas, and other dishes |
Culinary Applications of Tomato Paste Across Different Cuisines
Tomato paste shines in a variety of cuisines.
- Italian: Bolognese sauce, pizza sauce, lasagna, puttanesca.
- Mediterranean: Tagines, stews, sauces for grilled meats.
- Mexican: Salsas, enchilada sauce, chili.
- Indian: Curries, sauces for tandoori dishes.
- American: Chili, BBQ sauce, tomato soup.
Alternatives to Tomato Paste
If you don’t have tomato paste on hand, here are some substitutes:
- Tomato Puree: Use more puree than you would paste and cook it down longer to concentrate the flavor.
- Tomato Sauce: Similar to tomato puree, use more sauce and reduce it.
- Canned Tomatoes: Strain canned tomatoes to remove excess liquid and cook them down to a thicker consistency.
- Sun-Dried Tomato Paste: Can offer a similar concentrated flavor, although with a different taste profile.
Exploring Different Types of Tomato Paste
While most commercially available tomato paste is similar, slight variations exist. Some brands may add citric acid or salt to enhance flavor or preserve freshness. Organic options are also available. Exploring different brands can reveal subtle nuances in flavor and texture.
Frequently Asked Questions About Tomato Paste

Tomato paste, when used in moderation, can be a healthy addition to your diet. It’s a source of lycopene, a powerful antioxidant linked to various health benefits, and contains vitamins and minerals. However, be mindful of sodium content in some brands.
Can I freeze tomato paste?
Yes, freezing tomato paste is an excellent way to prevent waste. Freeze it in small portions using ice cube trays or resealable bags for easy use later. Thawed tomato paste may be slightly softer, but the flavor will remain intact.
How long does opened tomato paste last in the fridge?
Opened tomato paste typically lasts for 5-7 days in the refrigerator when stored properly in an airtight container. Look for signs of mold or discoloration, and discard if present.
Does tomato paste contain gluten?
Generally, tomato paste is naturally gluten-free. However, always check the product label to ensure that it wasn’t processed in a facility that also handles gluten-containing products.
Can I make tomato paste at home?
Yes! Making tomato paste at home is a rewarding process, although it requires time and patience. It allows you to control the ingredients and create a unique flavor profile. Many recipes are available online.
What is double-concentrated tomato paste?
Double-concentrated tomato paste has been cooked down even further, resulting in an even thicker consistency and more intense flavor than regular tomato paste. Use it sparingly.
What does tomato paste do for chili?
Tomato paste adds depth of flavor, richness, and body to chili. It also helps to thicken the sauce and creates a more cohesive texture.
How much tomato paste should I use in a recipe?

Can I use tomato paste in baking?
While not a common ingredient in most baked goods, a small amount of tomato paste can add a subtle savory note and enhance the color of certain breads or sauces.
Is there a difference between tomato paste in a tube versus a can?

Can tomato paste be used as a substitute for ketchup?
Tomato paste can be used as a base for homemade ketchup, but it needs to be diluted and seasoned with vinegar, sweeteners, and spices to achieve a ketchup-like flavor.
