How long can you keep fresh tomatoes in the freezer?
How long do tomatoes last in the freezer? Properly stored, they will maintain best quality for about 3 months, but will remain safe beyond that time. The freezer time shown is for best quality only - tomatoes that have been kept constantly frozen at 0° F will keep safe indefinitely.
- Hold a frozen tomato under warm running water for 20 to 30 seconds to thaw the skin.
- Set the peeled tomatoes in a bowl to thaw until they are soft enough to crush.
- Cook 2 to 3 tbsp.
- Stir continuously until the mixture boils.
- Allow the mixture to cool, then puree it in a blender.
- Wash, peel and chop raw, fully mature onions into about 1/2" pieces. There is no need to blanch onions. Bag and freeze in freezer bags for best quality and odor protection. For most dishes, frozen onions may be used with little or no thawing.
- Frozen cucumber pickles will last up to 12 months. Thaw containers overnight in the refrigerator before serving. Eat these freezer pickles like traditional pickles, or add to salads or dips. You can also freeze cucumbers by juicing or pureeing them with a little water.
- Boil for 30-60 seconds, remove tomatoes from the boiling water, and . . . . . . immediately put the tomatoes in an ice-water-filled sink or bowl. As they chill, you will see the skins start to pull away from the meat of the tomato.
How to Freeze Tomatoes
- Blanch. Drop tomatoes into boiling water for 60-90 seconds and, using a slotted spoon, transfer immediately into a bowl of ice water to cool.
- Prepare tomatoes. Remove stems and core tomatoes.
- Transfer into storage bags. Using a ladle or measuring cup, fill pint or quart sized ziploc bags.
- Seal bags.
- Into the freezer.
- When you take them out, your fresh tomatoes won't be squishy, and it will be easier to press the air out of vacant spaces before you seal the bags for long-term freezer storage. To ensure year-long storage of ripe tomatoes without any Freezer Burn, I purchased a FoodSaver Vacuum Sealing Machine, the V3835 Model.
- Take these steps to freeze cherry tomatoes:
- Choose ripe, unblemished cherry tomatoes.
- Wash cherry tomatoes, remove stems, and drain them in a colander.
- Set cherry tomatoes onto a cookie sheet so that their skins do not touch.
- Set the cookie sheet in the freezer for about an hour until the tomatoes are firmly frozen.
- To maximize the shelf life of canned or packaged tomato sauce after opening, refrigerate in covered glass or plastic container. To further extend the shelf life of opened canned tomato sauce, freeze it: to freeze tomato sauce, place inside covered airtight containers or heavy-duty freezer bags.
How to freeze peeled tomatoes
- After washing, dip raw tomatoes in boiling water for about one minute, or until skins split.
- Peel the skins off and place peeled tomatoes on cookie sheets. Put in freezer.
- Once frozen, remove tomatoes.
- Place tomatoes in freezer bags or other freezable containers.
- Preheat oven to 200 degrees F (95 degrees C).
- Wash and halve tomatoes. Gently squeeze out the seeds. Place the tomatoes on a non-stick cookie sheet, and sprinkle with salt to taste.
- Bake until tomatoes take on a leathery texture. This could literally take all day; smaller pieces will require less oven time.
- Do not store tomato paste in opened metal can - refrigerate in covered glass or plastic container after opening. Freeze tomato paste in airtight plastic containers or heavy-duty freezer bags, or spoon tomato paste into ice cube trays - once paste is frozen, transfer cubes to a heavy-duty freezer bag.
- Blanch the eggplant slices for 4 minutes, cool, and package in freezer bags. Remove as much air as possible before sealing bags. If you plan to use the frozen slices for making vegetable lasagna or eggplant parmesan, you can batter and bread the slices after blanching, wrap in wax paper, and freeze.
