Preheat the Air Fryer: Preheat your air fryer to 350°F (175°C). Preheating ensures even cooking and helps the bacon regain its crispy texture.

Prepare the Bacon: Place the leftover bacon in a single layer in the air fryer basket. You can add as many bacon strips as the basket can comfortably hold without overlapping.

Reheat the Bacon: Slide the air fryer basket back into the air fryer and reheat the bacon for about 2-3 minutes. The exact cooking time may vary depending on the thickness of the bacon and your desired level of crispiness.

Check for Desired Texture: Keep an eye on the bacon while reheating to avoid overcooking. After 2 minutes, open the air fryer, and using tongs, check the bacon's crispiness. If it's not quite to your liking, continue reheating for another 1 minute or so.

Remove and Serve: Once the bacon reaches your desired level of crispiness, carefully remove the air fryer basket from the machine. Transfer the reheated bacon to a plate lined with paper towels to absorb any excess grease.

Serve and Enjoy: Your reheated bacon is now ready to be served and enjoyed! Whether you use it as a side for breakfast, add it to sandwiches, salads, or enjoy it on its own, the air fryer will have brought back the bacon's delightful taste and texture.
