Start by slicing the bell peppers in half lengthwise and remove the seeds and membranes.
Place the bell pepper halves in the air fryer basket, cut side up. (If you're baking them in the oven add them peppers to a baking sheet.)
Crack an egg into each bell pepper half, being careful not to overflow the egg.
Sprinkle 1 tablespoon of cheese over each bell pepper.
Season with salt, black pepper, and garlic powder.
Carefully place the air fryer basket back into the air fryer and cook the bell peppers for 10-12 minutes, or until the eggs are cooked to your desired level of doneness.
Once cooked, remove the bell pepper egg boats from the air fryer and let them cool slightly before serving.
