If you have an entire avocado half, the best method is the Onion Airtight Container method I mentioned first. It can keep your avocado green for up to three days. That’s basically forever in avocado years.
If you only have slices (like for a salad tomorrow), lay them flat in a single layer inside a vacuum-sealed bag. If you don’t have a vacuum sealer, press the air out of a Ziploc bag with your belly (the belly is the best tool for this).
Never store sliced avocado with raw chicken. That’s a one-way ticket to Food Poisoning Island. Avocados are divas, not biohazards.

A Cautionary Tale
I once left a half avocado in the back of my fridge. It was there for a week. When I found it, the pit had sprouted a tiny root. I named it Gregory. Gregory is now a houseplant, and he judges me every time I make toast.
The takeaway: Eat your avocado within 48 hours. Even with all our tricks, it will eventually turn to brown mush. That’s just nature saying, “You snooze, you lose, pal.”
Also, surprising fact: The average avocado contains more potassium than a banana. But don’t tell bananas—they get jealous and turn brown out of spite.
Final Emergency Protocol
If all else fails and your avocado looks like a moldy fossil, chop off the brown bits. The rest is fine. The browning doesn’t penetrate deep. Scoop out the good green flesh and pretend the brown was never there.
Or just mash it up with lime, salt, and a jalapeño. Boom. You made guacamole, and all sins are forgiven. The avocado gods smile upon you.
Now go forth, store your green gold, and never eat a grey, flavorless avocado slice again. You are now a certified avocado storage ninja. Use your power wisely.
