Frittatas are so easy with just a few ingredients. This one-pan breakfast Frittata Recipe is extremely versatile - see the endless variations in the notes**.
Preheat the oven to 400F. Whisk eggs, heavy cream and salt until you get a smooth and even texture. Set aside.
Melt butter and coat the sides of the cast-iron skillet or baking dish with it. Spread vegetables and greens evenly on the bottom of the pan.
Pour over the egg mixture. Sprinkle the cheese on top. Using a fork, distribute the cheese around a little to incorporate it into the eggs. Bake for 15 to 17 minutes, or until the edges and center are set and the top is golden. The internal temperature of the frittata should reach 160˚F on a thermometer.
