How Long Does Greek Yogurt Last?
Greek yogurt lasts 1–2 weeks in the fridge. Once opened, plan to finish it within about 1 week. It freezes for 1–2 months, best for smoothies, dips and baking afterward.
Greek Yogurt — opened
shelf life- Unopened: 1–2 weeks in the fridge
- Prepared: 3–4 days in the fridge
Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Greek yogurt is regular yogurt strained to remove much of its whey, leaving a thicker, tangier, higher-protein product. It is just as acidic as ordinary yogurt, so it keeps about as long. Because it is so often used as a cooking ingredient, a big tub tends to be opened many times, which is what usually shortens its life.
How to store greek yogurt
- Smooth the surface flat with the back of a spoon before closing the tub; craters collect whey and the exposed peaks dry out.
- Always use a clean, dry spoon, and never return yogurt that has been mixed with garlic, fruit or honey to the tub.
- Store the tub upright toward the back of a shelf, where it stays at 40°F (4°C) or colder.
- Freeze leftover Greek yogurt in tablespoon-size mounds on a parchment-lined tray, then bag them, so you can drop measured amounts into smoothies or batters.
How to tell if greek yogurt has gone bad
- Fuzzy mold or pink, orange or gray patches on the surface or around the inner rim.
- A smell that has moved from clean and tangy to yeasty, cheesy or rancid.
- A fizzy or bitter taste, or a tub whose foil seal has puffed up.
- A watery, curdled texture throughout instead of a thick, spoonable one. A thin layer of whey on top is normal.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

Frequently asked questions
How long does Greek yogurt last after opening?
Opened Greek yogurt is best used within about 1 week, kept at 40°F (4°C) or colder. It may last longer in a clean, rarely opened tub, but each opening lets in mold spores and yeast. Single-serve cups should be eaten in one sitting or within a day or two.
Does Greek yogurt last longer than regular yogurt?
Not meaningfully. Both fall under the same 1–2 week refrigerator guidance. Greek yogurt is thicker because whey has been strained out, not because it has more preservative power, and its acidity is similar. Treat the two the same way.
Can I use Greek yogurt a week past its expiration date?
Possibly, if the container is still sealed, has been refrigerated the whole time and looks and smells normal when opened. The date is a quality guide. If the tub was already open, or there is mold, fizzing or a yeasty smell, throw it away. Appearance cannot rule out harmful bacteria, so stay cautious with anyone pregnant, elderly or immunocompromised.
Does Greek yogurt freeze well?
It freezes safely for 1–2 months but does not thaw to its original texture. The protein network breaks, leaving it grainy and watery. Whisking helps a little. Use thawed Greek yogurt in smoothies, marinades, muffins and pancakes, or freeze it sweetened as frozen yogurt bark that is eaten frozen.
