Step 1

Preheat an air fryer to 400 degrees F (200 degrees C). Spray a 4 1/2-inch ramekin with nonstick spray.

Step 2

Whisk eggs and cream together in a bowl. Stir in spinach, mushrooms, Cheddar cheese, salt, and pepper until well combined. Pour into the prepared ramekin and cover tightly with foil.

Step 3

Air-fry for 12 minutes. Remove foil and air-fry until top starts to brown and a toothpick inserted into the center comes out clean, 4 to 8 more minutes.
