How to Make Grilled Onion Frittata
- Preheat oven to 350°F (175°C).
- In a large bowl, combine the sliced red and yellow onions, salt, pepper, and olive oil. Toss to coat evenly.
- Preheat a grill pan over high heat.
- Arrange the onion wedges in a single layer on the hot grill pan. Cook for 5 minutes, until browned and slightly tender on the bottom.
- Flip the onions and cook for another 5-7 minutes, until very tender and caramelized.
- Transfer the grilled onions to a plate and set aside.
- In a separate large bowl, whisk together the eggs and heavy cream until light and frothy.
- Stir in the grated Gruyère cheese, salt, and pepper until well combined.
- In a 10-inch oven-safe skillet or braiser, melt the butter over medium-low heat. Add the chopped rosemary and cook for 1 minute, stirring constantly, until fragrant.
- Pour the egg mixture into the skillet. Gently fold to incorporate the rosemary.
- Arrange the grilled onions evenly over the top of the egg mixture.
- Transfer the skillet to the preheated oven and bake for 12-15 minutes, or until the frittata is set and golden brown on top and cooked through. The center should be just slightly jiggly.
- Let the frittata cool slightly before slicing and serving. Enjoy!
