How Long Are Leftovers Good in the Fridge?
Last reviewed: June 2026
Quick answer
Most cooked leftovers are good in the refrigerator for 3–4 days if they were cooled and refrigerated safely. If leftovers sat out more than 2 hours at room temperature — or more than 1 hour above 90°F — they should usually be thrown away instead of saved.
Safe window: 3–4 days, if stored promptly
Leftovers refrigerated within 2 hours (1 hour above 90°F) and kept at or below 40°F are generally good for 3–4 days. After that, discard them.
The 3–4 day leftover rule
The USDA recommends consuming most cooked leftovers within 3 to 4 days of refrigeration. Even when stored at or below 40°F (4°C) in a sealed container, bacteria continue to multiply slowly. By day 4, some foods may have bacterial counts that could cause illness — even if the food looks, smells, and tastes normal. See the official food-safety sources used by StillSafeFood for references.
When leftovers are not safe to save
The 3–4 day rule only applies if leftovers were refrigerated promptly in the first place. Leftovers are not safe to save — and the 3–4 day clock never really starts — if the food sat out too long before it ever went in the fridge. In that case, the safer choice is to discard it rather than refrigerate it and assume it's fine.
The 2-hour room-temperature rule
Leftovers should not sit out more than 2 hours at room temperature before being refrigerated. This is the same 2-hour rule that applies to all cooked food, not just leftovers specifically.
The 1-hour rule above 90°F
When the ambient temperature is above 90°F (32°C) — a summer cookout, a hot kitchen — the safe window before refrigerating drops to just 1 hour. Past that point, refrigerating the food does not make it safe again.
How to cool leftovers safely
- Divide large portions into shallow containers so they cool quickly and evenly.
- Avoid stacking hot containers tightly together — leave room for air to circulate.
- Don't leave food out "to cool down first" — refrigerate within the 2-hour window instead.
- For soups or stews, an ice bath under the container can speed up cooling.
How to store leftovers in the fridge
- Refrigerate within 2 hours of cooking (1 hour above 90°F/32°C).
- Keep the fridge at or below 40°F (4°C).
- Store in airtight containers to prevent contamination and odor transfer.
- Label containers with the date so you know when they need to be used or discarded.

Safe to eat
- Roast chicken refrigerated within 1 hour, eaten on day 3.
- Soup cooled in shallow containers, refrigerated the same day, used within 4 days.
- Pasta frozen on day 2, eaten within a few months.
Not safe — discard instead
- Casserole left on the counter overnight, even if refrigerated the next morning.
- Refrigerated leftovers that have been sitting for 8 days.
- Cooked rice left out for 3+ hours before it was refrigerated.
How to reheat leftovers safely
Reheat leftovers to 165°F (74°C), checked with a food thermometer, until steaming hot throughout. This guidance is for leftovers that were refrigerated promptly and stored within the 3–4 day window — reheating does not make leftovers safe if they sat out too long before refrigeration. See does reheating make food left out safe for a full breakdown.
Can you freeze leftovers?
Yes — freezing is a good option if you won't eat leftovers within 3–4 days. Keep the freezer at 0°F (-18°C) or below. Frozen leftovers stay technically safe indefinitely, but are generally best quality within 3–4 months. Label containers with the date before freezing.
What if leftovers smell fine?
Smell, taste, and appearance are not reliable safety tests. Visible mold, an off smell, or a slimy texture means discard immediately — but many pathogens, including Salmonella, Listeria, and Campylobacter, produce no obvious signs of spoilage. Use the 3–4 day guideline as your primary rule, not your senses.
What to do if leftovers were left out overnight
Discard them. Leftovers left out overnight have far exceeded the 2-hour (or 1-hour above 90°F) window, and refrigerating them at that point does not make them safe. See can leftovers sit out overnight for more detail.
What to do after a power outage
Check how long the power was actually out and whether the fridge stayed below 40°F. A closed refrigerator generally holds for about 4 hours, and a full freezer for about 48 hours. If you're not sure, the power outage food safety guide walks through what to keep and what to throw away. Not sure about a specific leftover?

Leftovers by topic
Cooked poultry follows the same 2-hour / 3–4 day rules as other leftovers.
Carries a notable Bacillus cereus risk if it sits out too long before refrigerating.
Cheese and meat toppings are perishable — refrigerate within 2 hours.
All cooked beef cuts follow the standard 2-hour (1-hour above 90°F) rule.
Perishable dairy follows the same room-temperature time limits.
US refrigerated eggs need consistent cold storage to stay safe.
Opened deli meat is generally good for 3–5 days once refrigerated promptly.
A closed fridge holds for about 4 hours; a full freezer for about 48 hours.
Reheating to 165°F applies to safely stored leftovers, not food left out too long.
This guidance follows USDA and FSIS food safety recommendations. Smell, taste, and appearance are not reliable ways to judge whether leftovers are safe — go by time and temperature instead. If you think you may have food poisoning, contact a healthcare provider.
Frequently asked questions
Are leftovers good after 5 days?
No. The USDA recommends discarding cooked leftovers after 4 days, even with no visible signs of spoilage.
Can I eat leftovers after a week?
No. A week is well past the 3–4 day guideline. Discard leftovers refrigerated for a week, even if they look and smell fine.
How long are cooked leftovers good in the fridge?
3 to 4 days at or below 40°F (4°C), per USDA guidelines.
How long are leftovers good in the freezer?
Safe indefinitely at 0°F or below, but best quality within 3–4 months.
Can I freeze leftovers after 3 days?
Yes, if they were refrigerated promptly and kept at or below 40°F. Freezing resets the storage clock.
What temperature should leftovers be reheated to?
165°F (74°C), checked with a food thermometer, until steaming hot throughout.
Are leftovers safe if they smell fine?
Not necessarily. Many bacteria don't change how food smells or looks. Go by the 3–4 day guideline, not your senses.
What if leftovers sat out overnight?
Discard them. Overnight far exceeds the 2-hour (1-hour above 90°F) safe window.
How long are leftovers safe after a power outage?
Depends on how long the power was out and whether the fridge stayed below 40°F — generally up to 4 hours for a closed fridge.
