Ingredients

• 4 large eggs
• 2 Tbsp whole milk or half‑and‑half
• ½ cup shredded Swiss cheese
• 1 cup mixed mushrooms (cremini, shiitake, button), sliced
• 1 Tbsp unsalted butter
• ½ tsp sea salt
• ¼ tsp freshly ground black pepper
• 1 tsp fresh thyme leaves (optional)
• Fresh chives for garnish

Step‑by‑Step Instructions

1. Prep the mushrooms. Clean the mushrooms with a damp paper towel and slice them evenly (about ¼‑inch thick). Set aside.
2. Whisk the eggs. In a medium bowl, crack the eggs, add milk, salt, and pepper. Whisk vigorously for 30‑45 seconds until the mixture is uniform and slightly frothy.
3. Heat the skillet. Place a non‑stick 10‑inch skillet over medium heat. Add the butter and let it melt, swirling to coat the surface.
4. Sauté the mushrooms. Add the sliced mushrooms to the pan. Cook, stirring occasionally, for 4‑5 minutes until they release moisture and turn golden brown. Sprinkle thyme (if using) during the last minute.
5. Reduce heat. Lower the flame to medium‑low. This prevents the eggs from cooking too quickly and ensures a tender interior.
6. Pour the egg mixture. Evenly distribute the sautéed mushrooms across the pan, then gently pour the whisked eggs over them, tilting the pan to cover the base.
7. Add the cheese. As the edges begin to set (about 30 seconds), sprinkle the shredded Swiss cheese over the entire surface.
8. Cover & steam. Place a lid on the skillet for 1‑2 minutes. The trapped steam will finish cooking the top while keeping the omelet fluffy.
9. Fold or slide. Once the center is set but still slightly glossy, gently fold the omelet in half with a spatula, or slide it onto a plate, folding it over the cheese.
10. Garnish. Sprinkle freshly chopped chives on top for a burst of color and mild onion flavor.
11. Serve immediately. Pair with toasted sourdough, avocado slices, or a light arugula salad for a complete brunch.
12. Enjoy! Relish the golden exterior, the airy interior, and the harmonious blend of mushroom earthiness with Swiss creaminess.

Pro Tips & Tricks

• Cold eggs, warm pan. Keep eggs refrigerated until whisking; the temperature contrast helps create a tender crumb.
• Don’t over‑beat. Whisk just until blended; over‑beating can incorporate too much air and cause the omelet to collapse.
• Use a non‑stick skillet. This ensures easy release and a smooth golden crust without sticking.
• Steam finish. Covering the pan for the last minute creates a gentle steam that sets the top without drying the eggs.
• Cheese distribution. Sprinkle cheese just before folding so it melts evenly and forms a silky layer.
• Season at the end. Taste the finished omelet and add a pinch more salt or a dash of hot sauce if desired.

Variations & Substitutions

Storage & Reheating

Refrigeration: Store any leftovers in an airtight container in the fridge for up to 24 hours. The texture will be softer, but still delicious when reheated.

Freezing: Not recommended for this omelet because the delicate texture can become rubbery after thawing.

Reheat: Microwave on medium power for 30‑45 seconds, or gently warm in a skillet over low heat, covered, until heated through.
