Preheat the Air Fryer: Start by preheating your air fryer to 350°F (175°C). This step ensures that the air fryer is hot and ready for reheating.

Arrange the Slices: Place the leftover meatloaf slices in a single layer in the air fryer basket. Make sure they are not overcrowded to allow for even reheating.

Reheat: Set the air fryer to reheat the meatloaf at 350°F (175°C) for 4-6 minutes. The exact time may vary depending on the thickness of your meatloaf slices and the air fryer model you're using.

Check Temperature: After a few minutes, use a meat thermometer to check the internal temperature of the meatloaf. It should reach 165°F (74°C) to ensure it's safely reheated.

Optional: Add Sauce or Gravy: If desired, you can add a small amount of sauce or gravy over the meatloaf slices before reheating. This helps keep them moist and adds extra flavor.

Serve: Once the meatloaf reaches the desired temperature, carefully remove it from the air fryer. Serve your reheated meatloaf slices with your favorite side dishes, and enjoy!
