How to Thaw Frozen Bananas: 4 Easy Methods

You know that bag of frozen bananas you bought for smoothies a few weeks ago? The one you’ve been meaning to use, but it’s just been sitting there in the freezer taking up space? You can’t even remember what brand they were—they’re all starting to look the same. 

But now you’ve finally run out of bananas and need to use those frozen ones! So how do you thaw them? 

This article will explain in detail how to defrost your frozen bananas: from a microwave, in cold water, and even under running water. 

The fastest way to thaw frozen bananas is in the microwave for 3-4 minutes at 50% power. 

Are Bananas Good After Being Frozen?

Bananas, unlike many other fruits, hold up really well to being frozen. 

You can safely freeze bananas for up to 6 months. The FDA recommended consuming them within 3 for peak flavor and texture though. 

When it comes to freezing bananas without their peels, place them into a plastic bag or container and seal them tightly before putting them into the freezer (it’s best if no air gets into contact with your fruit).

You can freeze bananas for your favorite banana bread or smoothie recipe no problem. 

If you’re using them for smoothies, you can usually use them straight out of the freezer. If you’re baking though, you’ll need to defrost them first.

How Do You Defrost Frozen Bananas?

1. Room Temperature Method

Remove your frozen bananas from the freezer and set them on the counter. They will usually be fully thawed within 2 hours. 

Make sure you place them in a bowl. As bananas thaw, they release a liquid and it can get messy!

If you freeze the bananas with their peels on, take a paring knife and cut off the peels. 

2. Refrigerator Thaw

Remove the bananas from the freezer and leave them in the fridge overnight. They should be thawed by morning. 

3. Microwave Defrost

At 50% power, microwave your frozen bananas for about three minutes (for 4-5 bananas). This is the quickest way to thaw your frozen bananas.

It’s important to watch the power level as you don’t want your bananas to start cooking. 

4. Water Bath Method

The cool water bath method is the most recommended for a safe and easy defrosting of your frozen bananas.

Step 1

Place your frozen bananas in a plastic bag, like a Ziploc bag. You don’t want the bananas to get soggy in the water. 

Step 2

Submerge your bag of frozen bananas in cool water. You don’t want the water to be too cold or it will take forever to thaw. Your hands should be comfortable in the water. 

Step 3

After 5 minutes, change out the water for some fresh water at the same temperature. Check your bananas by giving them a light squeeze. If they’re still frozen, put them in another water bath for 5 minutes. 

Step 4

Repeat until your bananas are completely thawed.

  • After thawing, bananas usually sit in a bunch of brown colored liquid. If you’re baking, you should strain this liquid away to keep your baked goods from becoming too dense. Or, if your recipe calls for a liquid, replace some of the liquid with the banana liquid. 
  • Date the container you freeze your bananas in. The FDA says they maintain their flavor for about 3 months. If you date the bag, you can make sure you use them before that time is up.
  • Peeling your bananas makes it easier when you thaw them or use them frozen for smoothies or ice cream. They also take up less room in the freezer and thaw faster. 
  • Freeze your bananas whole. When you’re looking at recipes, they often call for a specific number of whole bananas. It’s less of a guessing game when it’s time to defrost if you freeze them in that form. 
  • Frozen bananas are good for 3-6 months. However, after three months you’re looking at thawed bananas that will be on the mushier side of things. Using them in under 3 months is best. 


So, there you have it: our favorite ways to thaw a frozen banana. 

Each method works well. Which one is best for you depends on how much time you have and how they were frozen. 

The cool water bath comes highly recommended, but if you’re short on time, there’s always the microwave.
