Preheat an air fryer to 350 degrees F (175 degrees C).
Center a mason jar lid, upside down, on a 5-inch square of aluminum foil. Fold the foil up and around the lid to act as a round mold. Spray the foil with nonstick spray and crack egg into the center. Season with salt and pepper.
Place egg mold and frozen sausage patty next to each other in the air fryer basket; cook for 4 minutes. Flip sausage patty over, add English muffin halves, and cook 4 minutes more.
Place one English muffin half on a sheet of parchment paper. Add cheese, sausage patty, and egg. Top with remaining English muffin half. Wrap and go.
