Tiramisu is a creamy Italian dessert made with mascarpone, eggs, and coffee-soaked ladyfingers — but it’s also highly perishable. Knowing how long tiramisu lasts is important for both flavor and food safety. Whether homemade or store-bought, its shelf life depends on how it’s made and stored. Proper refrigeration, airtight packaging, and ingredient choices can help keep tiramisu fresh for several days while maintaining its rich texture and signature taste.

How Long Does Tiramisu Last in the Fridge
Homemade Tiramisu Shelf-Life in the Refrigerator
Homemade tiramisu typically lasts 2 to 4 days in the refrigerator when stored properly. Because it contains dairy products and sometimes raw eggs, it’s considered a perishable dessert. To maintain its best texture and flavor, tiramisu should be kept chilled at or below 4°C (40°F) in an airtight container. After four days, both the cream layer and soaked ladyfingers begin to lose quality and freshness.
Store-Bought Tiramisu Shelf-Life in the Refrigerator
Store-bought tiramisu generally lasts longer — about 5 to 7 days after opening — because it’s made with pasteurized ingredients and may include stabilizers or preservatives. If the packaging remains sealed and refrigerated, it can retain its quality toward the longer end of that range. Once opened, it should be consumed within a few days for the best taste and safety.
Factors That Shorten Fridge Storage Time
Several factors can shorten tiramisu’s shelf life even when refrigerated:
-
Raw eggs or unpasteurized cream: Increase the risk of bacterial growth.
-
Poor sealing: Exposure to air can dry out the cream and cause odor absorption.
-
Temperature fluctuations: Leaving tiramisu out or frequent opening of the fridge raises bacterial risk.
-
High moisture: Excess moisture can make the ladyfingers soggy and speed up spoilage.
Signs Tiramisu Has Gone Bad in the Fridge
Check for these signs before consuming stored tiramisu:
-
A sour or unusual smell (indicates spoiled dairy).
-
Watery or separated layers of cream.
-
Visible mold or discoloration on the surface.
-
Slimy texture or a taste that seems off.
If any of these signs appear, discard it immediately rather than attempting to scrape off spoiled parts.
How Long Does Tiramisu Last in the Freezer
Typical Freezer Lifespan
Tiramisu can last up to 2–3 months in the freezer when properly wrapped. Freezing extends its safety period but can slightly alter the texture of the cream and biscuits once thawed.
Best Practices for Freezing Tiramisu
-
Wrap tightly: Use plastic wrap and aluminum foil to prevent freezer burn.
-
Remove cocoa dusting: Add cocoa powder after thawing for a fresh look.
-
Portion before freezing: Slice into individual servings so you can thaw only what you need.
-
Label and date: Note the freezing date for easy tracking.
How Thawing Affects Quality and Texture
Thaw frozen tiramisu in the refrigerator overnight to keep it cool and safe. While the dessert remains edible, its texture may soften — the ladyfingers can absorb more moisture, and the cream layer might lose some of its firmness. Avoid microwaving to thaw, as it can cause separation.
When Freezing Is Not Recommended
Tiramisu isn’t ideal for long-term freezing. Over time, layers may separate, and ladyfingers can become overly soggy once thawed. It’s best to freeze only for short-term storage — within 2–3 months — for acceptable taste and texture.
How Long Does Tiramisu Last at Room Temperature
Tiramisu should not be left at room temperature for more than 2 hours. Because it contains mascarpone, eggs, and cream, it must stay cold to remain safe to eat. When kept above 4°C (40°F), bacteria can multiply quickly, increasing the risk of foodborne illness. Always return tiramisu to the refrigerator immediately after serving.
Ingredient & Recipe Variations: How They Affect “How Long Does Tiramisu Last”
Raw Eggs vs Pasteurized Eggs
Traditional tiramisu made with raw eggs should be eaten within 1–2 days, as it spoils faster. Using pasteurized eggs extends storage safety to 3–4 days.
Alcohol in Recipe
Liquor such as Marsala or rum offers a slight preservative effect but does not replace refrigeration. Alcohol may slow bacterial growth but cannot prevent it entirely.
No-Bake vs Baked Versions, Vegan/Dairy-Free Versions
-
No-bake tiramisu relies entirely on refrigeration and typically lasts 2–3 days.
-
Baked or vegan versions (using tofu or coconut cream) may last slightly longer, up to 5 days, if properly sealed.
Packaging and Layering (Glass Cups vs Large Tray)
Individual glass cups often last longer than large trays because they’re less exposed to air and moisture. Large trays may spoil faster once cut and opened, as each slice introduces air and bacteria.

Best Storage Practices to Extend How Long Tiramisu Lasts
-
Keep the fridge at or below 4°C (40°F): Prevents bacterial growth.
-
Use airtight containers: Limit air exposure and prevent odor absorption.
-
Cover with plastic wrap or foil: Maintains moisture balance and freshness.
-
Store away from strong-smelling foods: Cream easily absorbs odors from items like onions or cheese.
-
Label with preparation or opening date: Helps track safe consumption time.
-
For leftovers: Slice into portions before storing so only the serving needed is exposed to air.
-
For thawing: Always thaw in the refrigerator, never at room temperature.
Quality vs Safety: When to Eat vs When to Toss
Distinction Between “Still Safe to Eat” and “Best Quality”
Tiramisu may remain safe to eat for up to 4–5 days in the fridge, but its best quality — flavor, structure, and freshness — is within the first 2–3 days. After that, the cream may loosen, and the biscuit texture becomes overly soft.
Texture Changes Indicate Loss of Quality
Signs such as soggy ladyfingers, flattened cream, or muted coffee flavor show the dessert is past its ideal stage but may still be safe if no spoilage signs exist.
Safety Thresholds: Visible Mold, Off Smell, Separation = Toss
If tiramisu develops mold, sour odor, or curdled cream, it’s no longer safe. Even small mold spots or an unpleasant smell indicate contamination and should be discarded immediately.
“How Long Does Tiramisu Last” in Terms of Quality vs Safety
-
Best quality: 2–3 days (fresh flavor, ideal texture).
-
Safe to eat: Up to 4 days homemade, 5–7 days store-bought.
-
Frozen shelf life: 2–3 months, though with mild texture changes.
FAQs About How To Store Tiramisu
Can tiramisu last a week in the fridge?
Homemade tiramisu usually lasts up to 4 days, while store-bought versions can last 5–7 days if sealed and refrigerated properly.
How long does tiramisu last if it contains raw eggs?
Tiramisu made with raw eggs should be eaten within 1–2 days, as it spoils faster than versions made with pasteurized eggs.
How long can you freeze tiramisu and still enjoy it?
You can freeze tiramisu for up to 2–3 months. Beyond that, texture and flavor begin to deteriorate.
Does the alcohol in tiramisu make it last longer?
Only slightly. Alcohol slows bacterial growth a bit but does not prevent spoilage. Refrigeration is still essential.
How long can tiramisu sit out at room temperature?
No more than 2 hours. The dairy and eggs make tiramisu unsafe to eat if left out longer.
How can you tell if tiramisu is no longer good?
If it smells sour, looks watery, shows mold, or has separated cream layers, it’s no longer safe to eat.
Does store-bought tiramisu last longer than homemade?
Yes. Store-bought tiramisu usually lasts 5–7 days because it’s made with pasteurized ingredients and sealed packaging.
How does packaging affect how long tiramisu lasts?
Airtight packaging slows spoilage by limiting air exposure. Individual cups or sealed trays last longer than open or loosely covered containers.
Conclusion
Because tiramisu contains dairy and eggs, it doesn’t stay fresh for long at room temperature. Understanding how long tiramisu lasts helps you store it safely and enjoy it at its best. Homemade versions typically last up to four days in the fridge, while sealed store-bought ones can last about a week. Freezing can extend its life for up to three months, though slight texture changes may occur. The key is proper storage—keeping it cool, covered, and consumed promptly for the best quality.
