Can you freeze tomato paste?

Tomato paste, an intensely concentrated tomato sauce, is a valuable kitchen essential. Crafted by simmering and straining tomatoes, then reducing the mixture to a thick consistency, it comes in various variations with additives like citric acid, salt, herbs, or spices. 

Some are even double or triple-concentrated, but improper freezing can lead to spoilage.

So Can You Freeze Tomato Paste, And If Yes Then How Do We Freeze It?

How To Freeze Tomato Paste?

Freezing tomato paste is a handy solution for preserving this kitchen staple when you have more than you can use in one go. With the right approach, you can keep it fresh for several months. Here’s how:

  • Portion Control: Before freezing, consider portioning the tomato paste. Use an ice cube tray, or silicone molds, or spoon it onto a baking sheet in small portions. Once frozen, transfer the portions to an airtight container or a zip-top bag.
  • Seal It Tight: Ensure an airtight seal to prevent freezer burn. Remove as much air as possible from the container or bag.
  • Labeling: Don’t forget to label with the date, so you can keep track of its freshness.
  • Freeze: Place the sealed container or bag in the freezer. Tomato paste can be safely stored for up to six months.
  • Thawing: When you need tomato paste for your recipes, transfer the required portion to the refrigerator and allow it to thaw slowly.

How to Keep Tomato Sauce for Longer?

Here are some tips for making tomato sauce last longer:

  • Freeze sauce in freezer bags or containers, leaving 1/2 inch headspace. Frozen, it will keep for 2-3 months.
  • Can the tomato sauce be in jars using a water bath canner? Home canned sauce stored in a cool, dark place will last 12 months or longer.

  • Prevent contamination and food safety issues by following good kitchen practices when making sauce.

  • Discoloration – faded, grey, or dark spots means degradation has occurred.
  • Can rust, bulging, or dents – damage to the can compromise safety. Do not consume contents.
  • Expired date – paste well beyond the ‘best by’ date has decreased quality and safety.

How to Thaw Tomato Paste?

Thaw frozen tomato paste overnight by transferring it from the freezer to the refrigerator. This slower thawing helps maintain quality.

For a quick thaw, place the frozen tomato paste in a bowl of cold water. Change the water every 30 minutes so it stays cold. Gently turn the bag over in the water as it thaws.

Microwave thawing is not recommended. Microwaves heat unevenly and can cause hot spots that affect the color and flavor of tomato paste.

Once thawed, use the tomato paste immediately. Do not refreeze thawed tomato paste. Make sure the thawed paste retains its typical texture and scent before use. If signs of spoilage, discard them immediately.

How To Use Tomato Paste?

Tomato paste is a versatile pantry staple that boosts flavor. Here are some ways to use it:

  • Add 2-3 tablespoons tomato paste to stews, chili, soup, or braised meat to add rich umami flavor.
  • Mix 1-2 tablespoons into ground meat as a binder and season before making burgers or meatballs.
  • Stir a tablespoon into rice or grains before cooking for added flavor.
  • Whisk tomato paste into tomato sauce or gravy as a thickening agent.
  • Make a quick pasta sauce by sautéing garlic in olive oil, then adding tomato paste and cooking for 2-3 minutes. Finish with red wine.
  • Add tomato paste to roasted vegetables like eggplant or mushrooms. The rich sweetness balances out the bitterness.
  • Blend tomato paste with chickpeas, tahini, lemon, and spices for quick hummus.
  • Use in marinades and rubs for meats. The natural glutamates boost savory flavors.

Refrigerate leftover paste in an airtight container for 5-7 days. Freeze portions for longer storage.

How To Store Tomato Paste?

Follow these tips for properly storing tomato paste:

  • Store unopened cans in a cool, dry pantry away from direct sunlight. Avoid storage above the stove or near heat sources.
  • Write the purchase date on cans with a marker. Use the first-in first-out method, moving older cans to the front.
  • After opening, transfer the paste to an airtight container and refrigerate. Use within 5-7 days for best quality.
  • To freeze, divide into 1/4 or 1/2 cup portions in freezer bags or airtight containers. Remove excess air.
  • Place bags flat in the freezer until solid, then stack. Frozen tomato paste keeps 6-8 months at 0°F.
  • Look for signs of spoilage before use – mold, off smells, texture changes, or corrosion. Discard if compromised.
  • Do not store the paste in the can. Transfer to a container once opened. Tin can corrode over time, contaminating food.
  • When freezing, leave 1/2 inch headspace in containers as the paste will expand when frozen.
