Kitchen Smarts

Freeze ripe bananas that are just starting to get speckled brown. Bananas won’t keep ripening in the freezer or after thawing, so peel them before freezing for the best results.

The Best Way to Freeze Bananas

To Freeze Whole Bananas

Peel the bananas and lay them on a parchment- or wax paper-lined baking sheet in a single layer. Freeze for 1 to 2 hours, until firm.
Transfer the semi-frozen whole bananas to a freezer-safe zipper-top bag. Press out excess air, label with the date, seal, and return to the freezer.

Best for: Smoothies and milkshakes, or for baking where you will thaw and mash them first.

To Freeze Banana Slices

Peel and slice bananas into 1/2-inch rounds.
Arrange the slices in a single layer on a parchment-lined baking sheet.
Freeze for 1 to 2 hours, until firm.
Move the frozen slices into a freezer bag, press out excess air, label with the date, and store in the freezer.

Best for: Smoothies, milkshakes, frappes, and desserts that call for frozen banana slices.

To Freeze Mashed Bananas

Peel and mash bananas with a fork until smooth.
Portion the mash into airtight containers or freezer bags—measure 1/2 cup or 1 cup portions if you want consistent amounts for baking.
Flatten bags for easy stacking and faster thawing. Label each container or bag with the date and volume, then freeze.

Best for: Banana bread, pancakes, muffins, and banana bread pudding.

Storage Tips

Store frozen bananas for up to 4 months for best quality.
Use freezer-safe zipper bags or containers to reduce the risk of freezer burn.
Label bags with quantity (for example, “2 bananas” or “1 cup mashed”) so you can grab exactly what you need for recipes.
To reduce browning before freezing, toss slices or mash with a little lemon juice. Note that this can add a mild citrus note to the bananas.
Flash-freezing whole or sliced bananas on a tray prevents pieces from clumping together, making it easier to remove the exact amount you want.
