How to Make Grilled Onion Frittata

1. Preheat oven to 350°F (175°C).
2. In a large bowl, combine the sliced red and yellow onions, salt, pepper, and olive oil. Toss to coat evenly.
3. Preheat a grill pan over high heat.
4. 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.
5. Flip the onions and cook for another 5-7 minutes, until very tender and caramelized.
6. Transfer the grilled onions to a plate and set aside.
7. In a separate large bowl, whisk together the eggs and heavy cream until light and frothy.
8. Stir in the grated Gruyère cheese, salt, and pepper until well combined.
9. 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.
10. Pour the egg mixture into the skillet. Gently fold to incorporate the rosemary.
11. Arrange the grilled onions evenly over the top of the egg mixture.
12. 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.
13. Let the frittata cool slightly before slicing and serving. Enjoy!
