Preheat the air fryer: Set to 375°F (190°C). Let it run for 2–3 minutes so the basket is hot, which helps the tortilla crisp quickly.
Scramble the eggs: Whisk the eggs with milk or water, plus a pinch of salt and pepper.
Heat a nonstick skillet over medium, add butter or oil, and pour in the eggs. Stir gently until just set and still soft. Remove from heat immediately; they’ll finish gently in the air fryer.
Lightly toast the tortilla: Spray or brush one side of the tortilla with oil.
Place oiled side down in the air fryer basket and cook for 1–2 minutes until it’s warm and slightly pliable but not browned. This step prevents sogginess.
Assemble: Remove the tortilla to a board, oiled side down. Sprinkle half the cheese in the center, leaving a 1-inch border.
Spoon the soft-scrambled eggs on top. Add optional mix-ins like cooked bacon, sliced scallions, or a few baby spinach leaves. Top with the remaining cheese for an extra melty seal.
Fold neatly: Fold the sides toward the center, then fold the bottom up and roll tightly into a burrito-style wrap.
If your tortilla is stiff, microwave it for 10 seconds to make folding easier.
Crisp in the air fryer: Lightly spray the outside of the wrap. Place it seam-side down in the basket. Air fry at 375°F (190°C) for 5–7 minutes, flipping once halfway.
It’s done when the exterior is golden and crisp and the cheese is fully melted.
Rest and serve: Let it sit for 1 minute so the cheese settles. Slice in half for easier eating. Add hot sauce, salsa, or a dollop of Greek yogurt if you like.
