Elevate your air fryer hamburgers with the delicious combination of mushrooms and Swiss cheese. Sauté sliced mushrooms in a pan until they are tender and golden brown. Season your ground beef patties with salt and pepper, then cook them in the air fryer. Top each patty with sautéed mushrooms and a slice of Swiss cheese during the last few minutes of cooking. The result is a gourmet-style hamburger with a rich and savory flavor.
