Signs fried onions have gone bad
- A soft, greasy texture instead of a crisp crunch.
- An acrid, old-fryer smell from the oxidised oil.
- Any musty smell or visible mould.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store fried onions
Deep-fried onions soak up humidity and go from crisp to soft and greasy within weeks, and the frying oil oxidises too. Keep them airtight in glass — not the fridge, where they turn soggy — and revive limp ones with a quick pass in a dry pan or air fryer.
