Leftover ricotta from last night's lasagna is one of those fridge mysteries that nobody quite knows how to handle.
Most people assume it keeps as long as any other soft cheese, but ricotta's high moisture content makes it one of the faster-spoiling dairy products in your refrigerator.
The good news is that with the right container and a couple of simple habits, you can get every usable day out of it - and freeze what you won't finish in time.
Opened ricotta lasts 5-7 days in the fridge in an airtight container. Unopened, pasteurized ricotta keeps 7-10 days from the manufacture date. Frozen ricotta is safe for 2 months but turns grainy - use it only in cooked dishes after thawing.
How Long Does Ricotta Cheese Last?
Shelf life depends on two things: whether the container has been opened, and whether you're working with packaged pasteurized ricotta or a fresh batch made without stabilizers.

Packaged whole-milk or part-skim ricotta carries a reliable use-by date stamped on the tub - that date applies only while the seal is intact.
| Method | State | Duration | Notes |
|---|---|---|---|
| 🧊 Fridge | Unopened | 7-10 days | Count from manufacture date; check the use-by stamp on the tub |
| 🧊 Fridge | Opened | 5-7 days | Press plastic wrap to surface; shorter if ricotta came from a hot cooked dish |
| ❄️ Freezer | Opened/portioned | 2 months | Safe beyond that but texture degrades further; label with date |
| 🏠 Counter | Any | 2 hours max | Soft dairy enters the danger zone quickly; discard if left out longer |
Fresh homemade ricotta cheese - made without the stabilizers found in commercial tubs - sits at the shorter end of these windows. Expect 3-5 days refrigerated, and plan your meals accordingly.
Unlike something shelf-stable like the shelf life of sugar, ricotta gives you a narrow window that closes fast.
How to Store Ricotta Cheese
The original sealed container is your best option until you break the seal. Once opened, transfer ricotta to a shallow airtight container - shallower than the original tub, so less surface area is exposed to air.
Fridge: Spoon the ricotta into a clean airtight container, then press a sheet of plastic wrap directly onto the surface before snapping the lid shut. This limits both air exposure and whey pooling. If whey has already pooled, drain off 1-2 tablespoons before resealing; excess whey dilutes the curds and speeds up spoilage.
Counter: Keep ricotta out for no more than 2 hours total - during prep, serving, or cooling. That includes time spent on a warm stovetop nearby.
One overlooked habit: use a clean spoon every time you reach into the container. Introducing bacteria from a used utensil cuts days off the remaining shelf life.
Never double-dip.
Can You Freeze Ricotta Cheese?
Freezing ricotta works, with one honest caveat. Texture changes significantly - after thawing, the curds become grainy and slightly crumbly, and the creaminess you get from fresh ricotta won't fully return.
That said, frozen and thawed ricotta performs well in baked pastas, stuffed shells, pancake batter, and sauces where the texture difference is masked by heat and mixing.
- Portion first. Divide into recipe-sized amounts - typically ½ to 1 cup - so you thaw only what you need and avoid repeated freeze-thaw cycles.
- Pack tightly. Spoon into an airtight freezer-safe container or a heavy-duty freezer bag, then press out as much air as possible before sealing.
- Freeze flat. If using a bag, lay it flat in the freezer. It speeds thawing and stacks efficiently.
- Label with the date. Use within 2 months for best quality; beyond that it's safe but the texture degrades further.
- Thaw overnight in the fridge. Once thawed, stir or whisk to recombine the whey back into the curds before using.
If you're looking at other soft cheeses that behave similarly in the freezer, checking out mascarpone replacements or cream cheese alternatives can help when thawed ricotta still won't work for your recipe.
Signs Ricotta Cheese Has Gone Bad
Normal ricotta is white to ivory with a mildly milky, slightly sweet scent. A thin layer of separated whey on top is not spoilage - stir it back in, then smell.
Mold, ammonia smell, or sliminess means discard immediately - the whole container, not just the affected layer. Unlike hard cheeses where you can cut away mold, ricotta's soft, moist structure allows contamination to spread through the curds invisibly.
Getting the Most Out of Every Tub
Three habits separate ricotta that lasts the full week from a tub you pitch after three days.
- 🗓️ Check the use-by date at purchase - choose the latest date on the shelf, and plan your first use for within a day or two of opening.
- 🥄 Portion before you freeze - whole frozen tubs force you into a single all-or-nothing thaw, which usually means waste or texture loss across the board.
- 🔄 Don't mistake whey for spoilage - separated whey is normal; drain or stir it before concluding the ricotta is gone. If the smell and color are fine, it's still good.
- 🍝 Plan cooked uses for the final days - baked dishes and sauces tolerate slightly older ricotta far better than fresh applications do.
If ricotta consistently runs out before you can use it, ricotta cheese replacements like drained cottage cheese alternatives can fill in for most cooked applications.
Frequently Asked Questions
Opened ricotta lasts 5-7 days refrigerated in an airtight container. Ricotta that was heated in a cooked dish - like a stuffed shell filling - sits at the shorter end of that range.
Yes. Frozen ricotta becomes grainy after thawing, but lasagna and other baked pasta dishes mask that texture change completely. Thaw overnight in the fridge and stir before using.
A mild, lightly tangy smell can be normal for older ricotta - stir it and check for mold or sliminess. A sharp, ammonia-like, or fermented odor means discard it.
Yes - use a heavy-duty freezer bag, press out as much air as possible, and freeze it flat. Flat bags thaw faster and stack better than containers.
Press plastic wrap directly onto the surface before sealing the container - this limits air contact and slows whey separation. Draining off pooled whey before resealing also helps.
