Recipe Information
Ingredients
- 3 large eggs
- 1 medium onion
- 1 tablespoon butter
- 2 tablespoons heavy cream
- 1 ounce cheddar cheese
- 0.25 teaspoon salt
- 0.25 teaspoon black pepper
- 1 tablespoon fresh chives
Instructions
Begin by thinly slicing the medium onion into rings.
Heat a non-stick skillet over medium heat and add 1 tablespoon of butter. Allow the butter to melt and become slightly foamy.
Add the sliced onions to the skillet. Saute them for about 5-7 minutes, stirring occasionally, until they become golden brown and caramelized. Reduce heat if onions brown too quickly.
While the onions are cooking, crack 3 large eggs into a mixing bowl, add 2 tablespoons of heavy cream, 0.25 teaspoon of salt, and 0.25 teaspoon of black pepper. Whisk the mixture thoroughly until fully combined and slightly frothy.
Shred 1 ounce of cheddar cheese and set aside.
Once the onions are caramelized, spread them evenly across the skillet. Reduce the heat to low before pouring the egg mixture evenly over the onions, ensuring the eggs cover the entire skillet surface.
Allow the eggs to cook slowly for 2-3 minutes without stirring, until the edges begin to set.
Sprinkle the shredded cheddar cheese evenly over one half of the omelette.
Using a spatula, gently fold the omelette in half, covering the cheese, and press down gently to ensure even melting.
Continue cooking the omelette for an additional 2 minutes, or until the eggs are fully set and the cheese has melted.
Carefully slide the omelette onto a serving plate and garnish with 1 tablespoon of freshly chopped chives. Serve immediately.
