Split English muffins in half with a fork; preheat air fryer to 350°F (175°C) and toast muffins for 4-5 minutes until golden.

Spread butter evenly on toasted muffin halves; keep warm while preparing other ingredients.

Layer turkey bacon on one half of each muffin; substitute with preferred breakfast meat.

Grease ramekin and crack an egg into it; season with salt and pepper, and place next to muffins in air fryer.

Sprinkle shredded cheese over the egg in the ramekin; ensure even cooking space in air fryer.

Set air fryer to 400°F (200°C) and cook for about 8 minutes, checking egg doneness around 5 minutes.

Carefully remove ramekin; sprinkle additional salt and pepper. Assemble sandwich with egg on turkey bacon and top with muffin half.

Serve hot along with fresh fruit or crispy hash browns for a complete breakfast experience.
