Peach season has always been a big deal at our house. My middle daughter loved peaches, so every summer I bought them by the bagful and hoped I had chosen enough to last more than a few days.
I would leave those hard peaches sitting on the counter, wondering whether they were ever going to soften. Then, almost without warning, every peach in the bowl would seem to ripen at once.
Fortunately, peaches continue to ripen after they are picked, provided they were mature enough when harvested. The easiest way to speed up the process is to place them in a loosely folded paper bag at room temperature. Adding a ripe banana or apple can move things along even faster.
The Quick Kitchen Answer
The fastest practical way to ripen peaches is to place the unwashed fruit in a brown paper bag along with a ripe banana or a ripe apple. Fold the top of the bag loosely and leave it on the kitchen counter, away from direct sunlight.
Check the peaches once or twice a day. Remove each peach as soon as it smells sweet and gives slightly when pressed very gently.
Peaches that are already close to ripe may soften overnight. Very firm peaches usually need 1 to 3 days, depending on how mature they were when picked and how warm your kitchen is.
How to Do It
What You Will Need
- Firm, unripe peaches
- A brown paper lunch bag or paper grocery bag
- One ripe banana or apple, optional
Step-by-Step Instructions
- Sort the peaches first. Set aside any that are bruised, leaking, moldy, or already soft enough to eat.
- Place the firm peaches in the paper bag. Keep them in a loose, shallow layer rather than stacking them tightly.
- Add a ripe banana or apple. This step is optional, but it can help the peaches ripen faster.
- Fold the top of the bag loosely. Do not seal it tightly. The fruit still needs some airflow.
- Leave the bag at room temperature. Set it on the counter, away from direct sunlight, the stove, or other heat sources.
- Check the peaches at least twice a day. I usually check once in the morning and again later in the day.
- Remove peaches individually as they ripen. They will not necessarily all be ready at the same time.
Peaches bruise more easily as they soften, so avoid piling too many into one bag. A single layer is best when the bag is large enough.
Why It Works
Peaches naturally release ethylene as they ripen. When the fruit sits in an open bowl, most of that gas disperses into the room. A paper bag keeps more of the ethylene close to the peaches, which encourages them to continue ripening.
A ripe banana or apple produces ethylene too. Adding one to the bag gives the peaches a little extra help, which is useful when you are hoping to make peach cobbler tomorrow rather than sometime next week.
The bag should be folded loosely rather than sealed. You want to keep some of the ethylene near the fruit without trapping excess moisture around the peaches. That is also why a paper bag is a better choice than a tightly closed plastic bag.
What Works Best in My Kitchen
When I bring home several peaches, I sort them by how firm they feel instead of treating the whole bag as one batch.
The softest peaches stay on the counter so we can eat them first. Peaches that are firm but beginning to smell sweet go into a paper bag by themselves. The hardest mature peaches go into a separate bag with a ripe banana. I have used apples in the past--but, find that bananas work better for me.
I check both bags every morning and again later in the day. As soon as a peach becomes fragrant and gives slightly when touched, I take it out. We eat the peaches we can use right away and refrigerate the rest.
This little bit of sorting helps prevent the familiar peach-season problem of having six hard peaches on Monday, six perfect peaches on Tuesday, and six overripe peaches by Wednesday evening.
How to Tell When a Peach Is Ripe
Do not judge a peach only by the amount of red on its skin. That red blush may look pretty, but it does not necessarily tell you whether the peach is ripe.
Look for a combination of color, fragrance, and feel instead.
Look at the Background Color
Check the parts of the peach that are not red. A mature peach should generally have a creamy yellow or golden background rather than an obvious green tint.
A peach that is still very green may have been picked too early. It might soften on the counter, but it may never develop the sweetness and peach flavor you were hoping for.
Smell the Peach
A ripe peach should smell like a peach. You should notice a sweet, fruity fragrance without having to press your nose directly against it.
A peach with almost no scent probably needs more time. A peach that smells fermented or unusually sour may be past its best.
Press It Very Gently
Hold the peach carefully in your palm and gently apply light pressure with your fingers. A peach that is ready to eat should give slightly without feeling mushy.
Try not to press repeatedly with your thumb. That can leave bruised spots on the fruit before anyone has a chance to eat it.
Will Every Hard Peach Ripen Properly?
Unfortunately, not every hard peach will become a sweet, juicy peach.
The paper bag method works best when the peach is picked at a mature stage but is still firm enough to withstand packing, shipping, and handling at the store.
A peach with a creamy or yellow background usually has a better chance of ripening well at home. A very green peach that was picked before it fully matured may eventually become softer, but softening is not always the same as developing good flavor.
The paper bag can help a mature peach finish ripening. It cannot replace growing time that the peach did not receive before it was picked.
What to Do If You Need the Peaches Today
There is no reliable way to turn a completely hard peach into a soft, juicy peach in an hour or two. An oven or microwave may soften the fruit a bit, but that is cooking—not ripening.
If your peaches are too firm to enjoy fresh, they can still work in a recipe where heat (cooking) and added sweetness help them along. Slice them fairly thinly and use them in:
- Peach crisp or cobbler
- Grilled peaches
- Peach sauce or compote
- Peach muffins or quick bread
- Cooked oatmeal
- Homemade peach syrup
Taste the peaches before adding sugar. Firm, underripe peaches may need a little (or a lot!) more sweetener than fruit that ripened fully on the counter.
Mistakes to Avoid
Refrigerating the Peaches Too Soon
Cold temperatures slow the ripening process. Keep firm peaches at room temperature until they become fragrant and slightly soft.
Once they are ripe, refrigerate any you will not eat right away. For the best quality, try to use refrigerated peaches within about three to five days.
Forgetting to Check the Bag
Do not put peaches in a paper bag and ignore them for several days. Once they begin to soften, they can move from ripe to overripe surprisingly quickly.
A slightly bruised or damaged peach can also begin to spoil more quickly inside the bag, so check the fruit at least once or twice a day.
Using a Tightly Sealed Plastic Bag
A plastic bag may trap ethylene, but it also traps moisture. That damp environment can encourage mold and spoilage.
A loosely folded paper bag provides a better balance of ethylene exposure and airflow.
Washing Peaches Before Ripening Them
Wait to wash peaches until you are ready to eat or prepare them. Moisture left on the skin during storage can encourage mold and bacteria growth.
Store them unwashed, then rinse them thoroughly under running water immediately before using them.
Placing Them in a Sunny Window
Direct sunlight is not necessary for ripening. It may heat the fruit unevenly and cause the peaches to deteriorate before they ripen properly.
Room temperature and ethylene are what help the fruit ripen—not the heat from a sunny windowsill.
Squeezing the Peaches Too Hard
Peaches bruise easily, especially once they begin to soften. Test them with gentle pressure from your fingers and palm rather than poking firmly with your thumb.
Leaving Ripe Peaches in the Bag
Remove each peach as soon as it becomes ripe. Leaving soft peaches in the bag with a banana and several other ripening peaches can cause them to go overripe very quickly.
Frequently Asked Questions
Can I use an apple instead of a banana?
Yes. A ripe apple also releases ethylene and can be placed in the paper bag with firm peaches. Use whichever fruit you already have on hand.
Can nectarines be ripened using the same method?
Yes. Since nectarines are closely related to peaches, they can also be ripened in a loosely folded paper bag at room temperature. A ripe banana or apple can also be added to speed up the process.
Do peaches have to be kept apart inside the bag?
They can touch, but they should not be packed tightly or stacked heavily. Leaving a little room around the peaches reduces bruising and makes it easier to check each one as it ripens.
Can I reuse the paper bag?
Yes, provided the bag is clean and completely dry. Do not reuse a bag that contains fruit juice, mold, or pieces of spoiled fruit.
Things to Remember
A brown paper bag and a ripe banana or apple can help speed up the ripening of peaches, but choosing a mature peach in the first place still makes the biggest difference. Look beyond the red blush and check for a creamy yellow background rather than a green one.
Keep firm peaches at room temperature, check them regularly, and remove each peach from the bag as soon as it becomes fragrant and slightly soft. Refrigerate the ripe peaches you cannot use right away so the entire batch does not become overripe at once.
Peach season always seems too short. There is no reason to spend half of it waiting for a bowl of little baseballs to become edible—or letting every peach ripen before your family has time to enjoy them.
