Herby Greens and Goat Cheese Frittata

8 eggs

2 tsp. minced fresh rosemary

Pinch red pepper flakes

Kosher salt and freshly ground black pepper

4 T. unsalted butter

1 small onion, finely chopped

1/2 C. cherry or grape tomatoes

2 C. finely chopped leafy greens (Swiss chard, collards, mustard or kale)

4 ounces fresh goat cheese, at room temperature

 

Preheat the oven to 350 degrees F. Whisk together the eggs, rosemary, red pepper flakes, 1/2 tsp. salt and 1/4 tsp. black pepper in a bowl. Melt the butter in a cast-iron skillet. Add the onions and tomatoes, and sauté until the onions are soft and the tomatoes are starting to burst, about 5 minutes. Add the greens, 1/2 tsp. salt and some pepper; sauté for another 2 minutes. Turn down the heat to low and pour in the eggs. Using a rubber spatula, very gently move the eggs around a bit — not scrambling them, just massaging them into the cracks and crevasses of the greens. Once the eggs start to set on the bottom, dollop with the goat cheese and transfer the skillet to the oven. Bake until the frittata is set on top, 5 minutes.
