Instructions

  1. Step 1: Heat 1 tsp olive oil and 1 tbsp unsalted butter in a nonstick skillet over medium heat. Add 100 g sliced button mushrooms and sauté for 5-6 minutes until golden and their moisture has evaporated. Remove mushrooms and set aside.
  2. Step 2: In a bowl, whisk 3 large eggs with 1/4 tsp salt, 1/8 tsp black pepper, 1 tbsp chopped chives, and 1 tbsp chopped parsley until frothy.
  3. Step 3: Melt remaining 1 tbsp butter in the same skillet over medium-low heat. Pour in the egg mixture and cook for 2 minutes until edges start to set but center is still slightly runny.
  4. Step 4: Evenly distribute the sautéed mushrooms and 50 g grated Gruyère cheese over one half of the omelette. Cook for another minute until the cheese begins to melt.
  5. Step 5: Carefully fold the omelette in half using a spatula and cook for 30 more seconds. Slide the omelette onto a warm plate and serve immediately.
