The Best Ways To Reheat Lasagna
Since the best way to reheat any dish is via the same way it was first cooked, lasagna is best reheated in the oven at 350 degrees F, wrapped tightly in foil, for 30 to 45 minutes.
To reheat lasagna in a toaster oven, decrease the temperature slightly to 325 degrees F. Wrap the dish tightly in foil and bake until the edges sizzle and the cheese melts.
Your next best option is in the microwave. Add a spoonful or two of sauce, water, or broth, cover, and cook on medium for 60 to 90 seconds until heated all the way through.
You can also reheat lasagna in a skillet with ¼ cup of water per slice. Once the water simmers, cook at medium-low, covered, for about 20 minutes, uncovered for the last 5.
An air fryer is also a great choice for reheating lasagna. Simply preheat to 375 degrees F, and cook slices of lasagna tightly wrapped in foil for 10 to 20 minutes.
