Ingredients
Scale
Egg Mixture
- 8 large eggs
- 1/4 cup whole milk
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
Vegetables
- 1/2 cup diced yellow onion
- 1 cup chopped asparagus (trimmed)
- 1 cup sliced mushrooms (cremini or button)
Additional Ingredients
- 1 tablespoon olive oil
- 1/2 cup shredded Gruyère or Swiss cheese
- 2 tablespoons chopped fresh parsley (optional)
Instructions
- Preheat Oven: Preheat the oven to 375°F (190°C) to ensure it reaches the correct temperature for baking the frittata evenly.
- Mix Eggs and Milk: In a large bowl, whisk together the eggs, whole milk, salt, and black pepper until well combined and slightly frothy to incorporate air for a lighter texture.
- Sauté Onions: Heat olive oil in an oven-safe skillet over medium heat. Add the diced yellow onion and cook for 2–3 minutes until softened and translucent, releasing their natural sweetness.
- Add Vegetables: Stir in the chopped asparagus and sliced mushrooms. Cook for another 5–6 minutes until the vegetables are tender and any moisture from the mushrooms has evaporated to avoid sogginess.
- Pour Egg Mixture: Pour the egg mixture evenly over the cooked vegetables in the skillet. Let cook undisturbed for 2 minutes to allow the edges to start setting, which helps maintain the structure of the frittata.
- Add Cheese: Sprinkle the shredded Gruyère cheese evenly over the top to add a creamy and savory layer that melts beautifully during baking.
- Bake: Transfer the skillet to the preheated oven and bake for 12–15 minutes or until the frittata is puffed up and the center is fully set, indicating it’s cooked through.
- Rest and Serve: Remove from the oven and let the frittata rest for 5 minutes. This helps it firm up for easier slicing. Garnish with chopped fresh parsley if desired before serving.
Notes
- Gruyère cheese can be substituted with feta, cheddar, or goat cheese according to preference.
- Feel free to add chopped spinach or bell peppers to increase vegetable content and flavor variety.
- The frittata can be enjoyed warm straight from the oven or at room temperature, making it versatile for any meal time.
