Common questions
How long does frying oil last in the fridge?
1 month in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
Can you freeze frying oil?
Yes. Frozen at 0°F (−18°C), frying oil keeps best quality for 6–9 months. Frozen food stays safe indefinitely; the time is for taste and texture.
How can I tell if frying oil has gone bad?
Throw it out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
