Tomato Sauce Vs. Tomato Paste – An Essential Guide

Tomato sauce and tomato paste.

We think it’s time to unravel the complex supermarket wall of tomato products.  

The selection of tomato-related cans and jars can be mind-boggling as you work your cart through the canned vegetable aisle. Confused shoppers often ask the question how does tomato sauce compare to tomato paste? Let’s skip the long-winded intros and jump headlong into answering this question!

What’s the difference between tomato sauce and tomato paste?

Tomato sauce tastes like fresh tomatoes and has a thin, runny consistency. It is made by simmering fresh tomatoes until they lose their raw flavor. Most sauces add additional ingredients like herbs, spices, onion powder, salt, and pepper.

Tomato paste has a thick consistency with a highly concentrated, bold tomato flavor that’s similar to sun-dried tomatoes. Its purpose is to provide rich, umami flavor to dishes. Paste is made by slowly cooking down de-seeded tomatoes.   

Tomato sauce can be added to food without cooking. Paste needs to be cooked to tame its intense tomato flavor.

Did you know? In some countries, tomato sauce is a type of condiment that is bright red and sweet. It is similar in texture to ketchup and is often used on sausages and meat. It’s popular in New Zealand, Australia, the United Kingdom, and South Africa. This sauce is not what we are discussing in this article.


Although tomato sauce is cooked, it tastes like fresh tomatoes. Most store-bought sauces have additional seasonings added. Tomato paste has an intense, tart flavor that’s similar to sun-dried tomatoes. It should be used in moderation while tomato sauce can be used liberally in cooking.


Tomato sauce is quite watery while paste is thickened as it is cooked longer. The thinner consistency of tomato sauce makes it unsuitable for spreading onto pizza bases.

In the United States there are regulations around the two products: 

  • Tomato sauce: 8-24% tomato solids, not including the seeds or peel.
  • Paste: with tomato solids of no less than 24%.

Uses in the kitchen

Although you can use tomato paste and tomato sauce for cooking a wide range of dishes, they should not be used interchangeably. Their flavor and consistency are different.

  • Tomato sauce is usually a hero ingredient that’s front and center in the dish it’s added to.
  • Tomato paste is always a base ingredient, building up depth of flavor in food without playing the starring role.

Tomato sauce is excellent in pasta recipes, ratatouille, chili, meatloaf, shakshuka, and many other dishes. It is versatile enough to be slow-cooked with meat or vegetables for hours. This ingredient can also be added to eggs, chutney, or noodles at the end of cooking.

Sauce doesn’t need to be simmered for hours, although in some recipes, the tomato flavor improves once cooked. Its acidity will mellow after simmering for an hour.

Tomato paste is suitable for adding to sauces, tomato soup, pizza sauce, and casseroles. It works across a range of dishes where you want some punchy combination of sweetness and umami. Paste offers a “meaty flavor” and body to any dish without the extra liquid content that you get from either fresh tomatoes or tomato sauce.

You can intensify the delicious flavor of tomato paste by sautéing it with spices in a pan for a few minutes.

Quick tip: Too much tomato paste will overpower your meal with sweetness. If you’ve added too much, splash a little vinegar into your food to balance the flavors. Taste test and add more if needed.


Tomato sauce is synonymous with Italian cuisine, but it is believed to have originated from Mexico. It was originally a type of stew made of “peppers, pumpkin seeds, tomatoes, green peppers, fat tomatoes and other things that make tasty stews.” This recipe was first written about in the 1500s by Bernadino de Sahagun [source].

Tomato paste was created much more recently, in Southern Italy. Reduced tomato sauce was spread out onto boards and left to “cook” in the hot summer sun. Once the texture thickened, the paste was scraped off the board into balls.

Citric acid is usually the only ingredient added to the tomatoes during production of tomato paste. It adds acidity and works as a preservative.

Tomato sauce will usually include additional vegetables, herbs, and spices added. Homemade sauce will usually include olive oil as well.

Tomato sauce recipe

How to make tomato paste


  • 5 pounds tomatoes, quartered
  • 1 Tbsp olive oil
  • 1 tsp kosher salt
  •  ¼ tsp citric acid


  1. Preheat oven to 285°F (140°C).
  2. Add oil to a large pot on medium-high heat. Once hot, heat tomatoes until the peel begins to fall off.
  3. Process the tomatoes through a sieve into a large bowl or use a tomato press to make life easier.
  4. Add salt and citric acid to the tomatoes, then scoop, in a thin layer, onto baking trays or roasting pans. Bake for 3-4 hours, occasionally mixing, until the tomato turns into a paste-like texture. It will have reduced by roughly half its size when it’s ready. Also, check that there is no water remaining as this should have all dried out.
  5. Scoop the paste into preserving jars and store it until required. You can also freeze the paste in airtight containers for 4-6 months.
