How to Make a Cheesy Avocado Omelette

  1. Prep the Ingredients: Wash and prepare all veggies. Halve the grape tomatoes, finely chop the onion, and roughly chop the spinach and parsley.
  2. Sauté the Veggies: Heat the olive oil in a large non-stick skillet over medium heat. Add the red onion, seasoning with 1/4 teaspoon each of salt and pepper. Cook, stirring occasionally, for about 4 minutes until softened.
  3. Add Mushrooms and Spinach: Stir in the sliced mushrooms and continue to cook, stirring now and then, until mushrooms are just tender—approximately 4 minutes. Add the baby spinach and cook until just beginning to wilt, around 1 minute.
  4. Beat the Eggs: In a medium bowl, whisk together 4 large eggs and 2 egg whites until frothy. Season with a little salt and pepper if desired.
  5. Combine Eggs with Veggies: Pour the eggs over the sautéed vegetables in the skillet. Stir gently for 1 minute, then allow the mixture to cook undisturbed until the edges begin to set.
  6. Add Cheese and Tomatoes: Sprinkle the coarsely grated cheddar and grape tomatoes evenly over the eggs. Continue to cook without stirring, tilting the pan and loosening edges with a spatula for even cooking, until the omelette is nearly set but still slightly creamy in the middle.
  7. Finish and Garnish: Gently slide the omelette onto a plate, or fold it in half if preferred. Top with sliced avocado and parsley before serving.

Tips for the Perfect Omelette

  • Cook on Medium Heat: Avoid high heat which can cause eggs to cook unevenly and become rubbery. Gentle heat ensures a fluffy, tender omelette.
  • Don’t Over-Stir: After the initial gentle scramble, let the eggs cook undisturbed for the ideal texture.
  • Use a Non-Stick Skillet: Ensures easy release and prevents sticking.
  • Add Avocado Last: Slicing and adding avocado just before serving keeps it fresh and creamy, preventing browning or mushiness.

Expert Tips for Success

  • Use the freshest eggs possible for optimal flavor and texture.
  • Season veggies as you cook for maximum depth of flavor throughout the dish.
  • If using pre-shredded cheese, look for a variety without added starch for better melting.
  • Let the omelette rest off-heat for a moment before slicing; this helps the cheese set a little for a creamier bite.
