PrintEmail Lighter and more sophisticated than an omelet, but a great deal less fussy than a quiche, a frittata is a brilliant solution for an easy and elegant egg-based meal. You can substitute escarole or radicchio for the endive in this recipe. Ingredients 2 tablespoons extra virgin olive oil1 large red or white onion, thinly sliced1 head curly endive, chopped1 garlic clove, minced8 eggs4 tablespoons finely chopped fresh herbs (any combination of parsley, basil, cilantro or thyme)1/2 teaspoon salt1/4 teaspoon Freshly ground black pepper1 cup grated Gruyere cheese2 tablespoons freshly grated Parmesan cheese, divided Instructions Heat oil over low heat in a large nonstick skillet with an ovenproof handle. Add onion; cook, stirring occasionally, until soft but not browned, about 10 minutes. Add endive; cook, stirring occasionally, until tender and the moisture has cooked off, about 10 minutes. Add garlic. Lightly beat eggs in a large bowl. Stir in herbs, salt and pepper. Pour egg mixture into the skillet. Add Gruyère and 1 tablespoon Parmesan. Preheat broiler. Cook mixture in the skillet over very low heat without stirring until eggs are set on top but still moist, about 10 minutes. Remove skillet from heat. Sprinkle remaining Parmesan on top. Place skillet under broiler; broil until lightly browned on top, about 1 minute. Remove skillet from broiler. Slice frittata into wedges and serve.
