How to Ripen an Avocado: Simple Methods That Actually Work

To ripen an avocado, leave it on the counter at room temperature — that's all it takes. Most avocados ripen within 2–5 days on their own, and there are a couple of easy tricks to speed things up when you need one sooner. Here's everything you need to know, including one popular "hack" that doesn't really work.

How to Tell When an Avocado Is Ripe

The most reliable test is gentle pressure. Cup the avocado in your palm and give it a soft, even squeeze — it should yield slightly but not feel mushy or hollow. If it's rock-hard, it needs more time. If it dents and doesn't spring back, it's overripe.

• The stem test: Flick off the small stub at the top. If it comes away easily and the flesh underneath is green or pale yellow, the avocado is ready. If it's brown underneath, it may already be overripe inside.
• Don't rely on colour alone — especially here in the Philippines. Most local varieties, including the ones we grow at our avocados farm in Calauan, Laguna, stay green even when fully ripe. Colour is only a useful guide for dark-skinned Hass types.

The Fastest Way to Ripen an Avocado

Place your unripe avocado in a paper bag with a banana or apple, then fold the top loosely and leave it at room temperature. Bananas and apples release ethylene gas, a natural ripening hormone, and trapping it in the bag concentrates the effect around your avocado.

• Check daily — it can go from firm to perfectly ripe to overripe faster than you expect.
• A paper bag works because it breathes slightly. A sealed plastic bag traps too much moisture and can cause the skin to rot before the flesh softens.
• No banana? Another avocado in the same bag will do — they produce ethylene too, just less of it.

Plain Room-Temperature Ripening

If you're not in a hurry, simply leave the avocado on your kitchen counter away from direct sun. Most avocados bought slightly firm will be ready in 2–5 days depending on how unripe they started and how warm your kitchen is.

• Keep them in a cool, shaded spot — not near a window in the afternoon heat.
• Do not leave them in direct sunlight; the skin heats unevenly and the flesh can develop soft spots without ripening properly.
• Check by feel each day rather than waiting for a colour change.

What to Do Once It's Ripe

Once your avocado yields to gentle pressure, move it to the refrigerator immediately if you're not using it right away. Cold temperatures slow down the ripening process and will hold a ripe avocado in good condition for 2–3 more days. After that, quality drops quickly.

• For the best flavour, bring it back to room temperature for about 20 minutes before eating.
• If you've already cut it, read our guide on how to store avocados to keep the flesh from browning.

The Microwave Myth

You may have seen advice suggesting you microwave an avocado for 30 seconds to "ripen" it. This does not work. Microwaving softens the flesh by heating it, but it skips the enzymatic ripening process entirely — the flavour stays flat, the texture turns slightly greasy, and it won't have the buttery richness of a naturally ripened fruit. Save the microwave for reheating rice, not ripening avocados.

Quick Comparison: Ripening Methods

1. Paper bag + banana or apple — fastest (1–2 days sooner than countertop alone)
2. Counter at room temperature — reliable, hands-off, 2–5 days
3. Refrigerator (unripe) — slows ripening significantly; only use the fridge once ripe
4. Microwave — not recommended; softens without true ripening
