Simple Tips for Perfectly Reheating Leftovers
Lasagna—cheesy, saucy, and irresistibly gooey—what's not to love? This dish makes for a great make-ahead meal, but reheating it properly can sometimes be tricky. Thankfully, there are several methods to heat up your lasagna without turning the noodles into a dry mess. While the oven is the best choice, the microwave, stovetop, and even the air fryer are all effective options. Read on to discover how to reheat your lasagna leftovers like a pro.
What’s the most effective method for reheating lasagna?
The oven is the top choice when reheating lasagna. Whether it’s cold or frozen, heating it in the oven restores its original flavors and ensures a melty, gooey center. Simply cover the lasagna with foil and bake at 325°F (163°C) for 30 to 45 minutes for optimal results.

How to Reheat Lasagna Leftovers from the Fridge
Reheat lasagna leftovers in a 350°F (177°C) oven for 30 to 45 minutes. The most effective method for reheating lasagna that’s been stored in the fridge is using the oven. Place the lasagna in an oven-safe dish (if it’s not already), cover with foil, and bake for 30 to 45 minutes or until it's thoroughly heated.
- For a golden, crispy top, remove the foil and return the lasagna to the oven for an additional 5 to 10 minutes.
- Adding a little extra sauce or cheese on top can help retain moisture and prevent drying out during reheating.
Moisten lasagna with water before microwaving. Although microwaving isn’t the best method, it’s certainly the quickest. Place a slice of lasagna on a microwave-safe plate, sprinkle a small amount of water or extra sauce on top, and cover it. Heat for 1 minute, then continue microwaving in 30-second intervals until it's heated through.
- Cover the lasagna with a napkin, paper towel, or microwave-safe lid to keep moisture in.
- Note that microwaving can sometimes cause the lasagna to burn or become too crispy because it lacks moisture, so be sure to heat in short bursts.
Reheat single servings in a toaster oven. If you're only reheating a couple of slices, avoid preheating the entire oven. Instead, use a toaster oven. Place the slice(s) in a foil-lined dish and reheat at 325°F (163°C) for about 20 minutes or until heated all the way through.
Pan-fry lasagna leftovers for a crispy twist. Give your lasagna a crispy makeover by heating it in a frying pan. Cut the lasagna into thick slices, then place them in a frying pan or cast-iron skillet with a bit of olive oil over medium-high heat. Flip the slices occasionally until both sides are golden and the lasagna is thoroughly heated.
- If it takes too long for the center to heat up, cover the pan with a lid to help trap moisture and speed up the process.
How to Reheat Frozen Lasagna
Defrost the lasagna in the fridge overnight. Reheating frozen lasagna is similar to reheating leftovers from the fridge, but it requires a couple of extra steps. Start by moving the lasagna from the freezer to the fridge the night before you plan to reheat it.
- While overnight thawing is recommended, you can still reheat it from frozen, though it will take longer.
- If you forget to thaw it in the fridge, don’t worry! Just place it in the microwave on the defrost setting for about 5 minutes.
Let the lasagna sit at room temperature for 30 minutes. Before you begin reheating, leave the lasagna on the counter or table for 30 minutes. This helps the dish heat more evenly.
- To save time, consider doing this while your oven is preheating.
Cover the lasagna with aluminum foil. If it’s not already covered, now’s the time to wrap your lasagna tightly with aluminum foil. This will help retain steam and create an optimal cooking environment for even heating.
Bake the lasagna at 350°F (177°C) for about an hour. If the lasagna was cooked before freezing, set your oven to 350°F (177°C) and bake until it's heated through. If the lasagna was frozen uncooked, follow the original recipe’s instructions for baking.
- Depending on the size of your lasagna and whether it was fully defrosted, the baking time may need to be adjusted.
Remove the foil and bake for another 5 minutes. Once your lasagna is fully reheated, take it out of the oven and remove the aluminum foil. Return the dish to the oven and cook for an additional 5 to 10 minutes to crisp and brown the top.
- To speed up this process, you can use your oven’s broiler setting. Just be sure to watch the lasagna closely to prevent it from burning.
FAQs
Should you let your lasagna rest before serving? Absolutely! It’s best to allow your lasagna to rest for at least 10 minutes before serving. This helps the ingredients settle, making it easier to slice and serve without everything falling apart.
How do you reheat lasagna without drying it out? To keep your lasagna moist, add extra sauce to the top before reheating or cover it with foil. The additional sauce adds moisture, and the foil traps steam, preventing the lasagna from drying during the heating process.
Can you reheat lasagna in an air fryer? Yes, you can use an air fryer to reheat lasagna, though it may result in a slightly crispier texture than expected. While air fryers are quick, they can reduce the moisture in food. To prevent this, add extra sauce on top before reheating. Set your air fryer to 370°F (188°C) and cook for 6 to 10 minutes.
How can you tell when lasagna is heated through? To determine if your lasagna is fully reheated, check its internal temperature. A properly heated lasagna should reach 165°F (74°C). Use a food thermometer to ensure it's hot enough to serve.
