Grilled Onion Frittata

By AnneS

Ingredients

• 1 red onion, peeled and cut into 8 wedges
• 1 yellow onion, peeled and cut into 8 wedges
• Salt and pepper
• olive oil as needed
• 10 eggs
• 1/4 cup heavy cream
• 1/2 cup Parmigiano cheese
• 2 Tablespoon butter
• 1 teaspoon finely chopped rosemary

Preparation

Step 1

Preheat oven to 350 degrees. In a large bowl, combine onions, salt, pepper and oil and toss to coat well. Preheat a grill pan (or cast iron) over high heat. Arrange onion wedges on grill pan, and cook until browned and tender underneath--about 5 minutes; turn onions over and cook until very tender, 5-7 minutes more. In a large bowl, beat eggs and cream until blended. Stir in cheese, salt and pepper until smooth. In a 10" ovenproof fry pan over medium heat, melt butter, add rosemary and eggs. Arrange grilled onions over top of eggs, transfer pan to oven and bake until frittata is golden and cooked through, 12-15 minutes.
