Instructions
- Step 1: Whisk together 3 large eggs, 2 tbsp milk, 1/4 tsp salt, and 1/4 tsp black pepper until the mixture is smooth and slightly frothy.
- Step 2: Heat 1 tbsp unsalted butter in a non-stick skillet over medium heat. Add 1 cup sliced button mushrooms and 1 tsp fresh thyme leaves. Sauté for 5 minutes until mushrooms are golden and fragrant, then remove and set aside.
- Step 3: Add the remaining 1 tbsp butter to the skillet and pour in the egg mixture. Reduce heat to medium-low and cook undisturbed for 2-3 minutes until the edges start to set but the center is still slightly runny.
- Step 4: Evenly spread the sautéed mushrooms and 1/2 cup shredded Gruyère cheese over half the omelette. Using a spatula, fold the omelette in half and cook for another 1-2 minutes until the cheese melts and the eggs are fully set.
- Step 5: Slide the omelette onto a plate, garnish with 1 tbsp chopped chives, and serve warm.
