Quick, easy, and delicious! This Mushroom Leek Frittata combines earthy mushrooms, sweet leeks, and creamy Asiago cheese for a meal ready in just 30 minutes.
Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Place an oven-safe 9" non-stick skillet on your stovetop. Add the olive oil to the pan and turn the burner to medium-high heat.
Meanwhile, crack the eggs into a medium bowl and beat well. Whisk in the milk, salt, pepper, and 2 ounces (half) of the grated cheese.
Once the oil is hot, add the sliced mushrooms in a single layer. Cook, turning once, for 90 seconds per side. Add the sliced leeks and sauté for 3 minutes. Add the garlic and sauté for 30 seconds.
Pour the egg mixture into the pan and turn off the burner. Carefully transfer the pan to the center rack of your oven. Bake for 15 minutes, until set.
Remove the pan from the oven and top with the remaining 2 ounces of cheese. Run a spatula around the inside edge of the pan to loosen the frittata. Tilt the pan and use the spatula to tip the frittata out onto a flat surface. Serve garnished with scallions.
