Tomatoes are in peak season from June through September. That's when to look for fresh garden tomatoes at farmers markets, pick-your-own farms, or to harvest those you grew yourself. When selecting tomatoes for freezing, look for ones that are firm and richly colored. They should be free from blemishes, heavy for their size, and have a fragrant aroma. Perfectly ripe tomatoes will give just slightly to palm pressure.

Most varieties of tomatoes can be frozen. However, plum (roma) tomatoes contain the most pulp and will produce the best results. If you don't plan to freeze your tomatoes immediately, store them at room temperature. Avoid storing fresh tomatoes in the refrigerator, which can make them lose flavor and become mealy.

How to Blanch Tomatoes for Longer Storage

Blanching is a heat-and-cool process. It stops or slows natural enzymes in the tomatoes that could cause a loss of flavor and color. Blanch tomatoes before freezing if they'll be in your freezer for more than a couple of months. Blanching your tomatoes also makes easy work of peeling them. Here's how to freeze tomatoes after blanching them.

• Fill a large 7- to 8-quart pot with 1 gallon of water; bring water to boiling.

• Cut a shallow X on the bottom of each tomato using a sharp knife. This encourages the skin to split during blanching, so you can slip off the skin easily with your fingers once the tomatoes have cooled.

• Working in 1-pound batches, immerse tomatoes in the boiling water.

• Cook for 1 to 2 minutes or until the tomato skins split open.

• Transfer tomatoes to a large bowl of ice water using a slotted spoon.

Peel and Freeze the Tomatoes

When the tomatoes are cool enough to handle, use a knife or your fingers to peel the skin off the tomatoes.

• Using a small sharp knife, cut out the stem end from the peeled tomatoes.

• If desired, halve, slice, or chop tomatoes (you can also freeze whole tomatoes).

• Spoon the tomatoes into freezer containers or bags, leaving 1-inch headspace.

• Seal and label the container or bag.

• Freeze for up to 10 months.

Cooking with Frozen Tomatoes

If you're wondering how to use your tomatoes once you've stocked your freezer, there are a lot of different dishes you can make with them, such as Veggie-Pesto Lasagna Soup (substitute fresh tomatoes for canned) and Fresh Tomato Soup with Grilled Cheese Croutons. Use fresh tomato sauce in dishes like Zoodle Bowls with Tomato Sauce, Puttanesca Pasta Sauce, and Fresh Tomato Spaghetti Sauce.

But since freezing changes the texture of the tomato, you'll want to avoid using frozen tomatoes in recipes that call for fresh (like salads and sandwiches). Stick to tomato sauces, soups, and stews to make the most of your frozen tomatoes.
