Description

This fluffy Air Fryer Cheese Omelette is ready in just 10 minutes — no flipping required! A low-carb, keto-friendly breakfast made with simple ingredients you already have.

Ingredients 

For the Omelette

  • 2 large eggs, room temperature
  • 1/4 cup heavy cream
  • 1/4 cup sharp cheddar cheese, freshly shredded
  • 1/4 teaspoon salt
  • 1/8 teaspoon freshly ground black pepper
  • Cooking spray or 1 teaspoon butter, for greasing

Optional Add-Ins (up to 1/4 cup total)

  • 2 tablespoons bell pepper, diced
  • 2 tablespoons cooked ham, or bacon crumbles, diced
  • 2 tablespoons mushrooms, sautéed
  • 2 tablespoons fresh spinach, chopped
  • 2 tablespoons diced tomato, patted dry
  • 1 tablespoon chopped fresh chives or parsley

Instructions

  • Preheat: Set the air fryer to 350°F (180°C) and preheat for 3 minutes. Lightly grease a 6-inch oven-safe pan with cooking spray or butter.
  • Whisk the eggs: In a small mixing bowl, whisk together the eggs, heavy cream, salt, and pepper for 30 seconds, until the mixture is frothy with visible air bubbles.
  • First cook: Pour the egg mixture into the prepared pan. Place the pan in the preheated air fryer basket. Air fry at 350°F for 4 minutes.
  • Add cheese: Sprinkle the shredded cheddar evenly over the partially cooked omelette. Add any optional fillings now (cooked meats, sautéed veggies, fresh herbs).
  • Finish cooking: Air fry for another 4 minutes at 350°F, until the cheese is fully melted and the eggs are set but still tender.
  • Serve: Run a silicone spatula around the edges to release. Slide the omelette onto a plate, fold in half, and serve immediately.

Notes

Recipe Notes

Recipe Tips:
  • Room-temperature eggs cook more evenly than cold eggs.
  • Freshly grated cheese melts twice as well as pre-shredded.
  • Whisk for a full 30 seconds to incorporate air for maximum fluffiness.
  • If your air fryer runs hot, check the omelette at 6 minutes.
  • For extra-fluffy results, swap the cream for 2 teaspoons of water.
Substitutions:
  • Heavy cream → whole milk (1:1 swap)
  • Cheddar → mozzarella, Colby Jack, pepper jack, or feta
  • Dairy-free → omit the cream entirely
Storage: Refrigerate up to 3 days in an airtight container, or freeze wrapped individually for up to 2 months. Reheat in the air fryer at 320°F for 3–4 minutes.
Make It Keto: With 2g carbs per serving, this is naturally keto-friendly. Add cooked bacon and avocado to bump it up to a full keto meal.
