Ingredients:
- 1 tablespoon olive oil
- 1 tablespoon unsalted butter
- 1 large onion, thinly sliced
- 8 oz mushrooms, sliced (such as cremini or button)
- 8 large eggs
- 1/4 cup milk or cream
- 1/2 cup shredded Gruyère or cheddar cheese (optional)
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and pepper to taste
- Fresh parsley or chives for garnish (optional)
Instructions:
- Caramelize the onions: In a large ovenproof skillet, heat the olive oil and butter over medium heat. Add the sliced onion and a pinch of salt. Cook, stirring occasionally, for about 20 minutes, or until the onions are soft and caramelized. If the onions start to brown too quickly, reduce the heat to low.
- Sauté the mushrooms: Add the sliced mushrooms to the skillet with the onions. Cook for an additional 5-7 minutes, or until the mushrooms are tender and have released their moisture. Stir in the fresh thyme and season with salt and pepper to taste.
- Prepare the egg mixture: In a medium bowl, whisk together the eggs, milk or cream, and a pinch of salt and pepper. If using, stir in the shredded cheese.
- Cook the frittata: Pour the egg mixture over the caramelized onions and mushrooms in the skillet. Gently stir to distribute the vegetables evenly. Cook over medium-low heat for about 5 minutes, or until the edges of the frittata start to set.
- Finish in the oven: Preheat your oven’s broiler. Place the skillet under the broiler for 3-5 minutes, or until the top of the frittata is golden brown and the eggs are fully set.
- Serve: Remove the skillet from the oven and let the frittata cool slightly. Garnish with fresh parsley or chives if desired, and slice into wedges to serve.
Caramelized Mushroom and Onion Frittata is a versatile and flavorful dish that’s perfect for any meal of the day. Its rich, savory taste and satisfying texture make it a standout choice for both casual and special occasions.
