If you're a meal-prep warrior, here's your secret weapon: chopped onions freeze beautifully for up to six months. Just spread them on a baking sheet, freeze them solid (so they don't clump), then bag them up. They won't be crunchy for salads anymore, but they're perfect for soups, stews, and sauces.
Think of it as cryogenic preservation for your future self. Why chop every time when you can chop once and forget? Your inner lazy chef will thank you.
The Verdict: Use Your Senses, Not a Calendar
So, to answer the big question: chopped onions are good for about 7 to 10 days in the fridge—but that's a guideline, not a rule. Trust your eyes, your nose, and your fingers. If it looks dry, smells okay, and feels firm, you're good to go. If it's sad and slimy, let it go.
And hey, if you ever feel guilty about tossing a half-used onion, remember: you're not wasting food; you're respecting the beautiful, temporary nature of fresh produce. Isn't that kind of poetic? Now go make that omelet.
