Preheat the air fryer to 350°F (175°C) for 3–5 minutes.
A preheated basket helps the tortilla set into shape and crisp faster.
Prepare your bowl mold. Use an oven-safe ramekin, small metal bowl, or silicone mold that fits inside your air fryer. Lightly oil the inside so the tortilla doesn’t stick.
Shape the tortilla. Warm the tortilla in the microwave for 10–15 seconds to make it pliable. Press it gently into the bowl or ramekin so it forms a cup with raised sides.
Brush the inside with a thin layer of butter or oil.
Par-crisp the tortilla. Place the tortilla-in-bowl into the air fryer and cook for 2–3 minutes until the edges begin to firm up. This prevents sogginess once the eggs go in.
Whisk the eggs. In a small bowl, whisk the eggs with milk or cream (if using), plus a pinch of salt and pepper. Stir in onions, peppers, and cooked meat if using.
Fill the tortilla. Carefully remove the bowl from the air fryer.
Pour the egg mixture into the tortilla cup. Sprinkle cheese on top.
Air fry until set. Return the bowl to the basket and cook at 320–330°F (160–165°C) for 8–12 minutes, depending on your air fryer and desired doneness. Start checking at 8 minutes. The eggs should be just set in the center with a slight jiggle.
Optional crisp boost. If you want extra crispy edges, increase to 360°F (182°C) for the last 1–2 minutes.
Watch closely to avoid over-browning.
Finish and serve. Remove carefully—ramakins get hot. Let the bowl sit for 1 minute to finish setting. Add toppings like salsa, avocado, or cilantro.
Slice into wedges or eat straight from the bowl.
