How to Ripen Fruit Faster at Home (7 Proven Methods)

You went to the grocery store, picked up some avocados for tonight's dinner, and got home to discover they're hard as rocks. The peaches you bought for dessert could double as baseballs. The bananas are bright green and completely flavorless.

We've all been there. Most grocery store fruit is picked before it's ripe so it can survive shipping without bruising. That's great for supply chains, but terrible for people who want to eat fruit today, not next Thursday.

The good news is that you can dramatically speed up ripening at home using simple science. Here are seven proven methods, from the fastest to the most hands-off.

The Science Behind Fruit Ripening

Before diving into the methods, understanding one concept makes everything click: ethylene gas.

Ethylene is a natural plant hormone that fruit produces as it ripens. It's the signal that tells the fruit to soften, develop sugars, change color, and become aromatic. Some fruits produce a lot of ethylene (bananas, apples, avocados), while others are sensitive to it (peaches, pears, kiwis).

The key to ripening fruit faster is either trapping the ethylene gas around the fruit or providing extra ethylene from another source. Every method below works on this principle.

Important distinction: These methods only work on climacteric fruit — fruit that continues to ripen after being picked. Grapes, berries, citrus, watermelon, and pineapple are non-climacteric and won't ripen further once picked. If they were unripe at the store, they'll stay that way.

Climacteric Fruits (Will Ripen at Home)

Avocados, bananas, peaches, nectarines, plums, pears, mangoes, kiwis, tomatoes, cantaloupe, honeydew, papaya, figs, and persimmons.

Non-Climacteric Fruits (Won't Ripen Further)

Grapes, strawberries, blueberries, raspberries, cherries, oranges, lemons, limes, grapefruit, watermelon, pineapple, and pomegranates.

Method 1: The Paper Bag Trap

This is the gold standard ripening method. It's simple, effective, and requires nothing but a paper bag you probably already have.

How It Works

Place unripe fruit inside a brown paper bag. The bag traps the ethylene gas that the fruit naturally produces, creating a concentrated ripening environment. The paper is breathable enough to prevent moisture buildup (which would cause mold) while still containing the ethylene effectively.

Supercharge It With a Banana or Apple

To speed things up further, add a ripe banana or apple to the bag with the unripe fruit. Bananas and apples are ethylene powerhouses — they produce significantly more ethylene gas than most other fruits. The extra ethylene accelerates the ripening of whatever else is in the bag.

Expected Ripening Times (Paper Bag + Banana)

Fruit	Without Bag	Paper Bag Only	Paper Bag + Banana
Avocado	4-7 days	2-3 days	1-2 days
Peach	3-5 days	1-2 days	1 day
Pear	5-7 days	2-3 days	1-2 days
Mango	5-8 days	2-4 days	2-3 days
Banana (green)	5-7 days	2-3 days	1-2 days
Tomato	5-7 days	2-3 days	1-2 days

Check the bag daily by gently pressing the fruit. Remove it as soon as it yields to gentle pressure.

Method 2: The Rice Bowl Method (Best for Avocados and Mangoes)

Submerging unripe fruit in a bowl of uncooked rice creates an even more concentrated ethylene environment than a paper bag. The rice grains trap ethylene gas in the tiny air pockets between them, creating a super-concentrated ripening chamber.

How to Do It

Pour uncooked rice into a large bowl, nestle the unripe fruit into the rice so it's mostly or fully covered, and leave it on the counter. Check every 12-24 hours.

This method works especially well for avocados and mangoes, which respond strongly to concentrated ethylene. An avocado can go from rock-hard to perfectly ripe in 24-48 hours using this method.

Tip: Don't bury the fruit too deep if you're likely to forget about it. Over-ripe fruit in a rice bowl makes a mess.

Method 3: The Newspaper Wrap

Wrapping individual pieces of fruit in newspaper works similarly to the paper bag method but is better for larger quantities or very large fruit like melons.

How to Do It

Wrap each piece of fruit individually in a sheet of newspaper. Place the wrapped fruit in a single layer in a box or on a counter in a warm spot. The newspaper traps ethylene around each fruit while absorbing excess moisture.

This method is traditional for ripening tomatoes, mangoes, and pears in many cultures. It's particularly useful if you bought a whole box of unripe fruit at a farmers' market and need to ripen them gradually.

Method 4: Warmth Acceleration

Ethylene production increases with temperature, so placing fruit in a warmer spot speeds up ripening noticeably.

Best Warm Spots for Ripening

• On top of the refrigerator — Surprisingly warm from the motor heat below. A great spot for a paper bag of avocados.
• Near a sunny window — The warmth from sunlight accelerates ripening. Just don't let the fruit sit in direct sun for hours, which can cause uneven ripening or sunburn.
• Near the oven — If you've been baking, the residual warmth in the kitchen helps.

The ideal ripening temperature for most fruit is 68-77°F. Above 80°F, fruit can ripen unevenly or develop off-flavors. Below 60°F, ripening slows dramatically, which is why you should never refrigerate unripe fruit (unless you want to slow down ripening intentionally).

Method 5: The Oven Method (Emergency Speed for Avocados)

Need a ripe avocado right now for dinner? The oven method is the fastest option, though it comes with trade-offs.

How to Do It

1. Wrap the avocado tightly in aluminum foil.
2. Place it on a baking sheet and put it in the oven at 200°F.
3. Check every 10 minutes. Depending on how unripe it is, it may take 10-60 minutes.
4. Remove when it gives slightly to gentle pressure through the foil.
5. Let it cool in the fridge for 10-15 minutes before using.

The Trade-Off

The oven method softens the avocado by partially cooking it, not by true ripening. The texture will be right, but the flavor won't be as complex and buttery as a naturally ripened avocado. It works in a pinch for guacamole or toast but isn't ideal for eating plain.

This method is only recommended for avocados. Other fruits don't respond well to heat and will simply cook rather than soften appropriately.

Method 6: The Banana Bunch Strategy

If you buy green bananas regularly, this simple trick ensures you always have ripe ones available without planning ahead.

How It Works

Buy bananas at three different ripeness stages: a green bunch, a yellow bunch, and a spotted bunch. Use the ripe ones first, the yellow ones mid-week, and the green ones will be perfectly ripe by the weekend.

Separating the Bunch

Individual bananas ripen slower than bunches because bananas in a bunch share ethylene gas through their connected stems. If you want some to ripen faster and others slower, separate the bunch:

• Ripen faster: Leave bananas in a bunch or place in a paper bag
• Ripen slower: Separate individual bananas and wrap each stem in plastic wrap (this blocks ethylene from escaping through the stem)

Method 7: The Flour Canister Method

This old-fashioned method works on the same principle as the rice bowl but uses flour instead. It's particularly popular for ripening pears and persimmons.

Nestle the unripe fruit into a canister or deep bowl of flour. The flour creates an airtight environment that traps ethylene efficiently. Check daily and remove the fruit as soon as it's ripe.

Fruit-Specific Ripening Tips

Avocados

The paper bag + banana method is the most reliable. Check daily by pressing near the stem end — it should yield to gentle pressure when ripe. If you need only half an avocado, leave the pit in the unused half, wrap it tightly, and refrigerate. A squeeze of lemon juice on the exposed flesh prevents browning.

Tomatoes

Never refrigerate unripe tomatoes — cold temperatures kill the enzymes that develop flavor. Place them stem-side down on the counter at room temperature. A paper bag speeds it up, but counter ripening produces the best-tasting results.

Peaches and Nectarines

Place them on the counter in a single layer (not stacked, which causes bruising) with the stem side down. A paper bag with a banana ripens them in about a day. Once ripe, move to the refrigerator in produce storage containers to stop the ripening process and extend freshness by 3-5 days.

Kiwi

Kiwis ripen well at room temperature on their own, but a paper bag with an apple speeds it up dramatically. A ripe kiwi will yield slightly to thumb pressure, like a ripe avocado.

Mangoes

The rice method works best for mangoes. Place them in a bowl of rice and check daily. A ripe mango should give slightly when pressed and will have a sweet, fragrant aroma at the stem end. Once ripe, store mangoes in a fruit storage container in the fridge to keep them fresh longer.

How to Slow Down Ripening

Sometimes the opposite problem strikes — everything ripens at once and you can't eat it all fast enough. Here's how to pump the brakes.

• Refrigerate ripe fruit to slow ripening by several days
• Separate high-ethylene producers (bananas, apples) from sensitive fruit to prevent chain-reaction ripening
• Remove fruit from bags — the open air dissipates ethylene and slows ripening
• Freeze overripe fruit for smoothies, baking, or making frozen meal prep ingredients

If you're battling food waste from fruit going bad too fast, pairing these ripening tricks with good food waste reduction strategies keeps your grocery budget in check.

Frequently Asked Questions

Can I ripen fruit in a plastic bag instead of a paper bag?

A paper bag is better because it breathes, allowing some moisture to escape while trapping ethylene. A plastic bag traps too much moisture, which can lead to mold growth. In a pinch, a plastic bag with a few small holes poked in it works as a substitute.

Why do bananas ripen other fruit?

Bananas produce an exceptionally high amount of ethylene gas compared to other fruits. A single ripe banana produces enough ethylene to significantly accelerate the ripening of any climacteric fruit stored near it.

How can I tell if fruit is ripe without cutting it open?

For most fruit, gentle pressure is the best indicator — ripe fruit yields slightly when pressed. Color changes (green to yellow, for example) and aroma at the stem end are also reliable indicators. An unripe peach will have no smell; a ripe one smells sweet and fragrant.

Does putting fruit in the sun ripen it faster?

Indirect warmth from sunlight helps because it raises the temperature slightly. However, direct, prolonged sun exposure can cause uneven ripening, sunburn (yes, fruit can sunburn), and premature spoilage. A warm spot in the kitchen is better.

Is it true that unripe fruit has less nutritional value?

Slightly. As fruit ripens, starches convert to sugars and certain vitamins (especially vitamin C) increase. However, the difference is modest. The bigger issue is taste and texture — unripe fruit is significantly less enjoyable to eat, which means you're less likely to eat it at all.

Stop Waiting for Ripe Fruit

With these methods in your back pocket, you never have to plan three days ahead for a ripe avocado again. The paper bag + banana method handles 90% of ripening situations, and for emergencies, the oven or rice methods get you there even faster. Buy whatever the store has, bring it home, and ripen it on your schedule.
