Spinach Hash Brown Frittata Recipe

Preheat oven to 350 °. In a large skillet, saute onion in oil until tender. Add garlic; cook 1 minute longer. Stir in spinach, salt and pepper. Remove from heat. In another skillet, cook pancetta over medium heat until crisp. Remove to paper towels with a slotted spoon; drain. In a greased 11x7-in. baking dish, layer hash browns, spinach mixture and pancetta. In a large bowl, whisk eggs, milk, 1/2 cup fontina cheese, 1/2 cup cheddar cheese, parsley, Worcestershire sauce, mustard and nutmeg; pour over top. Sprinkle with remaining cheeses. Bake, uncovered, 35-40 minutes or until a knife inserted near the center comes out clean. Let stand 10 minutes before cutting.
