✔ Updated · Paper bag, fruit bowl + storage times
Bought rock-hard avocados and want guacamole this week? Here's how to ripen them faster, tell when they're perfect and keep them that way.
The fastest way to ripen avocados is to put them in a paper bag with a banana or apple, fold the top closed and leave it at room temperature. The fruit releases ethylene gas, and hard avocados usually ripen in 1 to 3 days instead of 4 to 5. Check daily: a ripe avocado yields to gentle pressure, especially near the stem.
- Fastest: paper bag + banana or apple, 1–3 days.
- Easiest: on the counter, 4–5 days.
- Slow it down: move ripe avocados to the fridge.
- Oven or microwave: softens, but doesn't truly ripen.
Why Avocados Ripen Off the Tree
Avocados don't ripen while they hang on the tree; they only start softening after they are picked. That's why most store avocados are hard. Like bananas and apples, they release ethylene, a natural gas that triggers ripening, and the more of it trapped around them, the faster they soften.
Warmth helps too. A warm spot in your kitchen (not hot, and out of direct sun) speeds things up, while the fridge almost stops ripening.
4 Ways to Ripen Avocados
| Method | Time | Best for |
|---|---|---|
| Paper bag + banana or apple | 1–3 days | The fastest real ripening |
| Paper bag alone | 2–4 days | No banana or apple at home |
| Fruit bowl with bananas | 3–5 days | Easy, hands-off |
| On the counter | 4–5 days | Avocados you'll use later in the week |
1. Paper Bag with a Banana or Apple (Fastest)
- Put the hard avocados in a brown paper bag with one ripe banana or apple.
- Fold the top over loosely so the ethylene stays in but some air can move.
- Leave the bag at room temperature, about 65–75°F, out of direct sun.
- Check every day by pressing gently near the stem. Most avocados are ready in 1 to 3 days.
- Skip plastic bags: they trap moisture and can make avocados go moldy.
2. Paper Bag Alone
No bananas? A closed paper bag still concentrates the avocado's own ethylene and ripens it in about 2 to 4 days. Adding two or three avocados to the same bag helps.
3. In a Fruit Bowl
Set avocados in a bowl next to bananas or apples. It's slower than the bag because the gas drifts away, but it's completely hands-off: expect about 3 to 5 days.
4. On the Counter
Simply leave them out at room temperature. Hard green avocados usually ripen in 4 to 5 days. This is my plan when I buy avocados on the weekend for tacos on Thursday.
Can You Ripen an Avocado in the Oven or Microwave?
Not really. Wrapping an avocado in foil and baking it at 200°F for 10 minutes, or microwaving it for 30 seconds, makes the flesh softer, but it doesn't develop the buttery, nutty flavor of a truly ripe avocado. It can also taste a little cooked or bitter.
If you're desperate, use a softened avocado in cooked or blended recipes, like a smoothie or a warm sauce, not in guacamole or on toast.
How to Tell If an Avocado Is Ripe
My mum taught me the test I still use in the store: cradle the avocado in your palm (no fingertips, they bruise it) and press gently near the stem. Ripe avocados give a little, like a firm peach.
- Hard and bright green: unripe; give it 4 to 5 days.
- Yields slightly, darker skin: ripe and ready for slicing or toast.
- Soft, very dark skin: perfect for guacamole, use today.
- Mushy, sunken or rattly pit: overripe; check inside for brown, stringy flesh.
- The stem cap: flick off the little nub. Green underneath means ripe; brown means overripe; if it won't budge, it's not ready.
- Color isn't everything: Hass avocados darken as they ripen, but varieties like Fuerte and Reed stay green, so trust the feel.
How to Store Avocados
- Unripe: on the counter, not in the fridge, or they may never soften properly.
- Ripe, whole: in the fridge for about 2 to 3 more days.
- Cut halves: brush the flesh with lemon or lime juice, leave the pit in, wrap tightly and refrigerate. Use within 1 to 2 days; scrape off any browned layer.
- Mashed: press plastic wrap right onto the surface and refrigerate for 1 to 2 days, or freeze for up to 3 months for smoothies and dips. Here's more on freezing guacamole.
Common Mistakes
- Squeezing with your fingertips bruises the flesh. Use your palm.
- Refrigerating hard avocados stalls ripening, and they can turn rubbery.
- Using plastic bags traps moisture and invites mold.
- Forgetting them in the bag. Check daily; the bag method works fast.

Frequently Asked Questions
How can I ripen an avocado quickly?
Put it in a closed paper bag with a ripe banana or apple at room temperature. The fruit gives off ethylene gas, which speeds up ripening, so most hard avocados soften in 1 to 3 days. Check them daily by pressing gently near the stem.
Can you ripen an avocado overnight?
Sometimes. An avocado that is already starting to soften can ripen overnight in a paper bag with a banana. A rock-hard, bright green avocado usually needs at least 1 to 2 days, even with the bag method.
Does putting an avocado in the oven ripen it?
No. Baking an avocado wrapped in foil at 200°F for about 10 minutes softens the flesh, but it does not develop real ripe flavor. Use an oven-softened avocado in cooked or blended recipes rather than guacamole.
Are green avocados ripe?
It depends on the variety. Bright green, hard Hass avocados are unripe and darken as they ripen. Some varieties, like Fuerte and Reed, stay green when ripe. The best test is feel: a ripe avocado yields slightly to gentle pressure in your palm.
Should you refrigerate avocados to ripen them?
No. Keep unripe avocados on the counter. The fridge slows ripening almost to a stop. Once an avocado is ripe, move it to the fridge to keep it at its best for about 2 to 3 more days.
