Instructions

  1. Step 1: In a bowl, whisk together 3 large eggs, 2 tbsp whole milk, 1/4 tsp salt, and 1/8 tsp black pepper until smooth and slightly frothy.
  2. Step 2: Heat 1 tbsp unsalted butter in a nonstick skillet over medium heat. Add 1 small finely chopped shallot and 1 cup sliced button mushrooms, sautéing for 5-6 minutes until mushrooms release moisture and become golden.
  3. Step 3: Pour the egg mixture evenly over the mushrooms in the pan. Sprinkle 1/4 cup grated Gruyère cheese and 1 tsp fresh thyme leaves evenly over the eggs.
  4. Step 4: Reduce heat to low and cook for 3-4 minutes until eggs are mostly set but still slightly creamy on top. Use a spatula to gently fold the omelette in half.
  5. Step 5: Slide the folded omelette onto a plate and garnish with 1 tbsp chopped fresh chives. Serve immediately with crusty bread if desired.
