Paste tomatoes are bred for their dense, meaty flesh and low moisture content, making them the backbone of thick sauces. So, what are paste tomatoes exactly, and why do they matter so much in the kitchen? In simple terms, they are the workhorses of the tomato world, designed to cook down into rich, concentrated flavors without turning your stove into a watery mess.
Unlike the juicy slicing tomatoes you use in salads, paste tomatoes have fewer seeds and less juice. Their firm walls and solid interior mean you get more usable pulp per pound. This makes them the top choice for canning, making ketchup, and creating that perfect pizza sauce that clings to the dough without making it soggy.
What Are Paste Tomatoes
To fully understand their value, it helps to look at their physical traits and how they differ from other types. Paste tomatoes are usually oblong or pear-shaped, though some heirloom varieties are more rounded. They feel heavy for their size, which indicates a thick wall and a small seed cavity.
When you cut one open, you will notice the flesh is firm and almost dry. There is very little of that watery gel that surrounds seeds in regular tomatoes. This low water content is the secret to their success. It means your sauce reduces faster, and you do not need to simmer it for hours to get a thick consistency.
Key Characteristics Of Paste Tomatoes
- Low moisture: Typically 75-80% water, compared to 90-95% in slicing tomatoes.
- Thick flesh: The walls are dense and solid, not hollow.
- Fewer seeds: Makes them easier to prep and process.
- Meaty texture: Holds shape when cooked, but breaks down smoothly.
- Concentrated flavor: Often sweeter and more intense than fresh-eating types.
These traits are not accidental. They are the result of selective breeding over centuries. Growers wanted a tomato that could be cooked down quickly, stored well, and provide a rich base for winter meals. The result is a category of tomatoes that excel in the pot rather than on the plate.
Popular Varieties You Should Know
There are many types of paste tomatoes, but a few stand out for home gardeners and cooks. The most famous is the Roma, also known as the Italian plum tomato. It is reliable, productive, and has a classic flavor profile.
Another favorite is the San Marzano, which is considered the gold standard for Neapolitan pizza sauce. It has a sweeter taste and a more elongated shape than the Roma. For those who want something different, the Amish Paste is a large, irregular heirloom with a rich, complex flavor. It is less uniform but offers a unique depth.
Other notable mentions include the San Marzano Gigante, which is a larger version of the classic, and the Viva Italia, known for its disease resistance and high yields. Each variety has subtle differences in sweetness, acidity, and texture, but they all share that essential low-moisture quality.
Why You Should Grow Paste Tomatoes
If you have a vegetable garden, adding paste tomatoes is a smart move. They are generally more productive than slicing varieties, giving you a large harvest from just a few plants. Because they have less juice, they also store better on the vine and are less prone to cracking in wet weather.
Growing them is not difficult, but they do need full sun and consistent watering. You should stake them or use a cage, as the plants can get heavy with fruit. Once they start ripening, you will have a steady supply for weeks. This is perfect for batch cooking and freezing.
How To Use Paste Tomatoes In Cooking
The most common use is making tomato paste, which is a concentrated form of the fruit. To do this, you simply cook down the tomatoes until almost all the water is gone, then strain out the seeds and skins. The result is a thick, rich paste that can be stored in jars or frozen in ice cube trays.
You can also use them for making fresh salsa, though the texture will be chunkier than with regular tomatoes. They are excellent in stews, soups, and curries where you want a robust tomato flavor without excess liquid. Even a simple dish of pasta with fresh tomato sauce benefits from their intensity.
Here is a simple method for making a basic sauce:
- Wash and roughly chop 5 pounds of paste tomatoes.
- Cook them in a large pot over medium heat for 20 minutes, until soft.
- Run them through a food mill to remove skins and seeds.
- Return the puree to the pot and simmer on low heat.
- Stir occasionally until it thickens to your desired consistency.
- Add salt, basil, or garlic to taste.
This process takes about an hour, but the flavor is far superior to anything from a can. You can also add a little olive oil to the sauce to help it thicken and prevent sticking.
Canning And Preserving With Paste Tomatoes
Because of their low acidity and high solids, paste tomatoes are ideal for canning. They are safe for water-bath canning if you add a bit of lemon juice or citric acid to ensure the pH is low enough. This is a great way to preserve your summer harvest for the winter months.
When canning, always use a tested recipe to avoid food safety issues. The process is straightforward: prepare the tomatoes, fill the jars, and process them in a boiling water bath. The result is a pantry full of ready-to-use sauce base that you can pull out anytime.
You can also dry paste tomatoes in a dehydrator or a low oven. Dried tomatoes have an intense, sweet flavor and can be stored in oil or used as a snack. This is a great way to use up a glut of fruit at the end of the season.
Nutritional Benefits Of Paste Tomatoes
Like all tomatoes, paste tomatoes are packed with vitamins and antioxidants. They are an excellent source of vitamin C, potassium, and vitamin K. They also contain lycopene, a powerful antioxidant that has been linked to reduced risk of certain cancers and heart disease.
Because they are more concentrated, you get more of these nutrients per serving compared to watery tomatoes. The cooking process actually increases the bioavailability of lycopene, so your homemade sauce is even healthier than eating them raw. This makes them a great addition to a balanced diet.
They are also low in calories, with about 20 calories per medium tomato. The fiber content is decent, which helps with digestion. If you are watching your sugar intake, note that they do contain natural sugars, but the amount is relatively low compared to other fruits.
Common Mistakes When Cooking With Paste Tomatoes
One common error is adding too much water during cooking. Since the tomatoes are already low in moisture, you should not need to add any liquid unless you are making a very thin soup. Adding water will only dilute the flavor and lengthen the cooking time.
Another mistake is overcooking them, which can make the sauce taste bitter. You want to cook them just until they break down and thicken, not leave them on the stove for hours. Taste as you go and stop when the flavor is bright and fresh.
Finally, do not forget to season. Paste tomatoes are naturally sweet, but they need salt to balance the acidity. A pinch of sugar can also help if the tomatoes are particularly tart. Fresh herbs like basil and oregano add a wonderful aroma, but add them at the end to preserve their flavor.
Frequently Asked Questions
Can I Use Regular Tomatoes Instead Of Paste Tomatoes?
Yes, but you will need to cook them much longer to evaporate the extra water. The flavor will be less intense, and you may need to add tomato paste to thicken the sauce. For best results, stick with paste tomatoes when making sauce.
Are Paste Tomatoes Good For Eating Fresh?
They can be eaten fresh, but they are not as juicy or sweet as slicing tomatoes. Some people enjoy them in salads for their firm texture, but they are really best when cooked. If you want a fresh snack, choose a different variety.
How Do I Know When Paste Tomatoes Are Ripe?
They are ripe when they are fully colored (usually red, but some varieties are yellow or orange) and slightly soft to the touch. They should come off the vine easily. Do not wait until they are overly soft, as they can become mealy.
Can I Freeze Paste Tomatoes Whole?
Yes, you can freeze them whole. Just wash them, remove the stems, and place them in a freezer bag. When you are ready to use them, run them under warm water and the skins will slip right off. They will be softer when thawed, but perfect for cooking.
What Is The Best Way To Peel Paste Tomatoes?
The easiest method is to score an X on the bottom, blanch them in boiling water for 30 seconds, then plunge them into ice water. The skins will peel off easily. This is a quick step that makes a big difference in your sauce texture.
Final Thoughts On Using Paste Tomatoes
Paste tomatoes are a versatile and essential ingredient for any cook who loves rich, homemade sauces. Their unique structure makes them perfect for reducing down into thick, flavorful bases that elevate any dish. Whether you grow them yourself or buy them at the market, they are worth the effort.
