Ingredients
Method
- Preheat broiler with rack 6 inches from heat. Melt butter in an 8-inch oven-safe skillet over medium heat. Add mushrooms and a pinch of salt; cook until golden, about 4 minutes.
- Whisk eggs with 1/4 tsp salt, pepper, and half the cheese.
- Pour egg mixture into skillet over mushrooms. Reduce heat to medium-low and cook without stirring until edges are set, 2 to 3 minutes.
- Sprinkle remaining cheese on top. Broil until puffed and golden, 2 to 3 minutes. Slide onto a plate, scatter chives if using, and slice while hot.
Notes
Let the frittata rest for a minute after it comes out of the broiler so the slices hold together cleanly. If your skillet handle isn’t oven-safe, wrap it tightly in foil.
