Ingredients
Method
- Heat oil in a 10-inch oven-safe nonstick skillet over medium heat. Cook onion until soft, 3 to 4 minutes. Add garlic and cook 1 minute. Stir in zucchini with a pinch of salt; cook until wilted and liquid evaporates, 2 to 3 minutes.
- Whisk eggs, salt, pepper, and Parmesan. Pour over zucchini, swirl pan, and lift set edges to let uncooked egg run underneath. Cook until bottom and edges are set but top is runny, 2 to 3 minutes.
- Broil 6 inches from heat until puffed and golden, 2 to 4 minutes. Let rest 1 minute, then slide onto a board, slice, and serve with extra Parmesan.
Notes
Broilers vary, so watch closely after the 2-minute mark. The frittata will continue to cook from residual heat as it rests, so pull it when the center still looks a little soft.
