Leftovers can save you time and money, but only if they still taste good the second time around. Dry chicken, rubbery pasta, and soggy pizza aren’t anyone’s idea of dinner. The good news: most leftovers can taste almost as good as fresh if you use the right method and add a little moisture back in.
This guide walks you through the best way to reheat the foods you cook most often, which appliance to use for what, and the food safety basics every home cook should know.
The 3 Golden Rules of Reheating
- Add moisture. A splash of water, broth, milk, or sauce creates steam that keeps food from drying out.
- Cover it. A lid, damp paper towel, or foil traps that steam around the food.
- Go low and slow. Blasting food on high heat dries out the outside before the inside warms up. Medium or low heat gives more even results.
Food Safety Basics
- Refrigerate within 2 hours. Put leftovers in the fridge within 2 hours of cooking (1 hour if it’s very hot out).
- Use within 3 to 4 days. That’s the USDA guideline for most cooked leftovers in the fridge.
- Reheat to 165°F. Use an instant-read thermometer, especially for meat, poultry, and casseroles.
- Reheat once. Only warm what you plan to eat, rather than reheating the whole container again and again.
- Store in shallow containers. Food cools faster and more safely in shallow containers than in one deep pot.
Which Appliance Should You Use?
- Microwave: Fastest. Best for soups, stews, rice, pasta with sauce, and casseroles.
- Stovetop: Best for anything saucy, stir fries, and pasta. Gives you the most control.
- Oven: Best for large portions, roasts, casseroles, and baked dishes. Slower, but very even.
- Air fryer: Best for anything that should be crispy: fries, pizza, wings, fried chicken, and roasted vegetables.
How to Reheat Common Leftovers
Chicken
Slice chicken breasts before reheating so they warm quickly and evenly. On the stove, warm the slices in a covered pan with 2 tablespoons of broth over medium-low heat for 3 to 5 minutes. For crispy chicken like wings or fried chicken, use the air fryer at 375°F for 4 to 6 minutes.
Steak
Steak dries out fast. Warm slices in a skillet over low heat with a small pat of butter for 1 to 2 minutes, or place a whole steak in a 250°F oven until warmed through, then sear quickly in a hot pan.
Rice
Sprinkle 1 to 2 tablespoons of water over each cup of rice, cover with a damp paper towel, and microwave for 1 to 2 minutes, stirring halfway. Cool leftover rice quickly and eat it within a day or two, since cooked rice that sits at room temperature can grow bacteria.
Pasta
For pasta with sauce, reheat on the stove with a splash of water or milk, stirring often. For plain pasta, dip it in boiling water for 30 to 60 seconds. Creamy sauces like alfredo should always be reheated on low heat with extra milk so they don’t separate.
Pizza
Skip the microwave. Put slices in a cold skillet, cover, and heat over medium-low for 4 to 6 minutes until the bottom is crispy and the cheese is melted. The air fryer at 350°F for 3 to 4 minutes also works well.
Soups and Stews
Reheat on the stove over medium heat, stirring occasionally, until simmering. Add a splash of water or broth if it’s thickened in the fridge.
Roasted Vegetables and Fries
Use the air fryer at 375°F for 3 to 5 minutes or a hot oven at 400°F for 5 to 8 minutes. The microwave will make them soft.
Casseroles and Lasagna
Cover with foil and bake at 350°F for 20 to 30 minutes until hot in the center. For a single portion, microwave covered at 50% power so the edges don’t dry out before the middle warms.
Microwave Tips That Make a Big Difference
- Arrange food in a ring. Leave the center of the plate empty. Food heats more evenly that way.
- Use 50% power for meat, casseroles, and creamy dishes. It takes a little longer but heats much more evenly.
- Stir halfway through to get rid of cold spots.
- Let it rest for 1 minute after heating so the heat spreads.
Foods That Don’t Reheat Well
Some foods are better eaten cold or made fresh: fried eggs, delicate fish like cod, salads with dressing, and anything battered and fried in the microwave. When in doubt, turn leftovers into something new, like a frittata, fried rice, or a wrap.
Frequently Asked Questions
Is it safe to reheat food more than once?
It’s best to reheat only the portion you’ll eat. Every time food cools and reheats, quality drops and the chance of bacteria growth goes up.
How do I know leftovers are hot enough?
Check the center with an instant-read thermometer. It should read 165°F.
Why does my microwave make food rubbery?
High power overheats the proteins. Lower the power to 50%, add a splash of liquid, and cover the dish.
Can I reheat food in plastic containers?
Only use containers labeled microwave-safe, or move the food to a glass or ceramic dish before heating.
How long can leftovers stay in the freezer?
Most cooked dishes keep good quality for 2 to 3 months. Label containers with the date so nothing gets forgotten.
Put Your Leftovers to Work
