Preheat the air fryer: Set to 375°F (190°C). Lightly spray or line the basket to prevent sticking.

Cook the bacon: Lay bacon in a single layer in the basket. Air fry for 6–8 minutes, flipping halfway. Cook time depends on thickness. Transfer to a paper towel to drain.

Toast the bread: Split your English muffin or slice your bread. Lightly spread butter or mayo on the cut sides. Air fry cut-side up for 2–3 minutes until golden.

Cook the egg: You have two options: Ramekin method: Lightly grease a small, oven-safe ramekin. Crack in an egg, season with salt and pepper, and place in the air fryer. Cook 4–6 minutes for set whites and a jammy yolk (longer for fully set).

Free-form method: Place a small square of parchment in the basket. Crack the egg onto it, season, and air fry 3–5 minutes until the white is set to your liking.

Melt the cheese: Place cheese on the bottom half of the warm bread and air fry for 30–45 seconds until just melted.

Assemble: Layer bacon over the cheese, add the egg, and finish with any extras like hot sauce or greens. Cap with the top half of the bread.

Optional re-crisp: For an extra-crunch finish, put the assembled sandwich back in the air fryer for 1 minute at 350°F (175°C).

Serve: Eat right away while the bread is crisp, the bacon is crunchy, and the cheese is gooey.
