The best bananas for banana bread: how ripe should they be?

What makes banana bread so flavorful? Is it the touch of vanilla? A hint of cinnamon? Just the right balance of salt and sweet?

All of the above. But the most critical flavor in banana bread, the one that’ll make or break your loaf, is (no surprise) — banana. So if you want to make out-of-this-world banana bread, it’s important that you use the “right” bananas.

You’re standing in the produce section at your grocery store, looking at the bananas. There’re big ones and little ones. Organic bananas, and cute little bunches of mini-bananas.

Which do you choose?

It’s simple: the ripest ones.

Search out overripe bananas

Look beyond the “perfect” bananas, and see if you can find a rolling cart with reduced-price produce: bruised apples, soft lemons, wilted lettuce — and “overripe” bananas. A banana that’s way too squishy and soft for your cereal is just perfect for banana bread: the blacker the banana, the sweeter and more assertive its flavor.

If you can’t find overripe bananas, you’ll need to create your own. Buy some bananas — which in most supermarkets are typically yellowish-green, or yellow tinged with green at the stem end.

These bananas may be a bit too ripe for your cereal, but they’re just beginning to come into their own for banana bread.

Let the bananas ripen (and overripen) at room temperature. Depending on the weather, this could take a few days, or up to a week.

The best bananas for banana bread aren’t yellow; they’re black. Or they’re at least streaked with black/brown, with just the barest hint of green at the stem. And again, the darker the better: there’s no such thing as a too-ripe banana when you’re making banana bread.

Obviously, this is a pain if you don’t tend to plan your baking projects well ahead, and you want to make banana bread immediately. If you’re a spur-of-the-moment baker, it pays to keep a stash of ripe bananas on hand at all times — in your freezer.

Build a stash of frozen overripe bananas

How does that work? Very well! Every time you see a banana in the fruit bowl teetering between just right and Fruit Fly Central, stick it in the freezer. I have a zip-top plastic bag full-time in my freezer for just this purpose.

Frozen bananas turn dark brown or black; that’s perfectly OK. When you’re ready to bake, take out the bananas you need and let them thaw at room temperature. Or thaw them in the microwave (skin and all); my microwave takes about 3 minutes to thaw four medium bananas.

Thawed bananas are very soft and watery; again, no worries. Simply slit their peels lengthwise and squeeze the squishy dark bananas into your mixing bowl (if you bake by weight) or measuring cup. They’ll be very soft and easy to mash. Do include any liquid.

You can also simply slice off the tip and squeeze the soft banana into your bowl or cup like you’re squeezing a tube of toothpaste.

Caveat emptor: You may have seen tips online for roasting under-ripe bananas in their skin for 30 minutes in a 350°F oven. This is supposed to concentrate their flavor and make them sweet. I tried it; they were indeed deep black, but they tasted like green bananas, only mushy. Don’t go there.

Finally, what if you just have to make banana bread right now — your best friend is dropping by and you promised her… but you don’t have any overripe bananas on hand?

Use whatever bananas you can get. Increase the sugar in the recipe by about 15% (generally 2 to 3 tablespoons) to help with the missing sweetness; and increase the salt by about 25% to help with flavor intensity.

Now this doesn’t apply to the completely green bananas you’ll sometimes see at the supermarket. So if that’s all you can find, just make pumpkin bread and call it a day!

Have you made our Whole-Grain Banana Bread yet? It’s our 2018 Recipe of the Year, for many reasons — not the least its shower of crunchy cinnamon-sugar on top. I think I must have made this bread 40 to 50 times in the last six months, and it’s a runaway hit everywhere I share it. What are you waiting for? Go buy some bananas!

    I remember back as a young child, my siblings took and hide 3 bananas from the new bunch just purchased. At later time, my mother found 3 over-ripe banana on the counter and she baked one of famous banana bread.

    I really prefer banana bread made with frozen bananas, I think It intensifies the banana flavor. I remember years ago watching one of
    Alton Brown’s show where he explained the science behind this. All I know is it works!

    I used slimey frozen banana slices I found in my freezer (I let them thaw a little, then smushed them still in the bag before dumping them into the mixer) for your whole grain banana bread and my husband said it was the best banana bread he’d had in a long time! I don’t usually like banana bread and I thought it was great!

    Because of some health problems, I cannot use whole wheat flour nor sugar. So I made the recipe with white flour and Splenda instead of sugar, though I did use real sugar on top since I didn’t know if Splenda would carmelize. It still made great bread, but cut the carb level significantly.

    I had black bananas on hand so I thought I would give this recipe a try. I threw in about one cup of mini chocolate chips. It came out so good, my coworkers even raved about it. And the recipe came together very easily. Thanks KAF!

    I also freeze over ripe bananas…however, I peel them first. When thawed, all the juices are then simmered and reduced in a pan on the stove to intensify the flavor. (for example, if you have 1/2 cup, reduce to 1/4 cup) I read this little tip in one of Dorie Greenspans books (I think it was her). I have always avoided making banana bread due to the slight banana flavor, but this method has me knocked out!! Absolutely delicious……….

    I like to peel the overripe bananas, then weight them out (340 gms per bag), mark the bags, and freeze. Then when I make the KAF Banana Bread the correct amount is already in the bag – much easier that way! Although I may have to check out the amount required for the Whole Wheat version and try that one soon.

  8. Michele Morrison

    I find that I need to defrost the bananas in a bowl because there is a lot of liquid that will end up on the counter or microwave otherwise.

      Good question, Kels! Mold is bad. Black skin is fine, but the banana itself shouldn’t have any mold, and usually just gets to a dark caramel brown. Annabelle@KAF

    My gramma taught me years ago to throw the over ripe bananas in the freezer for banana bread. And I have to say, your whole wheat recipe is the best I’ve ever made. Earlier this evening my husband came home with a bag of brown bananas from the reduced price cart at the grocery and hinted strongly that they’d make GREAT BREAD.
