For a gourmet twist on the classic hamburger, try this mushroom Swiss air fryer hamburger recipe. Start by sautéing sliced mushrooms with garlic and butter until they are tender and golden brown. Cook the hamburger patties in the air fryer, then top them with the sautéed mushrooms and slices of Swiss cheese. Let the cheese melt slightly before serving the burger on a toasted bun. The combination of juicy beef, earthy mushrooms, and creamy Swiss cheese will take your burger game to a whole new level.
