Ingredients
- 2 tablespoon sextra virgin olive oil
- 3/4 cup thinly slice d shallots, from 2 to 3 shallots
- 5 oz baby spinach (about 5 packed cup s)
- 1/2 teaspoon salt
- 8 large eggs
- 1/3 cup heavy cream
- 1/4 teaspoon freshly ground black pepper
- 3/4 cup shredded Cheddar cheese
- 1/2 cup Parmigiano Reggiano
- 1/4 cup fresh chopped basil
Instructions
- Preheat the oven to 325°F, and set an oven rack in the middle position.
- Heat the oil in a 10 inch cast iron or ovenproof nonstick skillet over medium heat. Add the shallots and cook, stirring frequently, until softened, 3 to 4 minutes. Do not brown. Add half of the spinach and cook until wilted down, about 1 minute. Add the remaining spinach and ¼ teaspoon of the salt and continue cooking until all of the spinach is wilted, 1 to 2 minutes more.
- In a large bowl, whisk together the eggs, heavy cream, pepper, and the remaining ¼ teaspoon of salt.
- Add the cooked spinach mixture, Cheddar, Parmigiano Reggiano, and basil to the egg mixture and stir to combine.
- Pour the mixture back into the pan (no need to wash it), then place it in the oven and bake until set, 20 to 23 minutes.
- Immediately place an oven mitt over the pan handle to remind yourself that it is hot (it's easy to forget and burn your hand, and the handle stays hot for a long time).
- Serve the frittata directly from the pan, or use a rubber spatula to loosen the edges and slide the frittata onto a serving platter.
- Freezer Friendly Instructions: The cooked frittata can be frozen for up to 3 months. Remove the frittata from the freezer about 24 hours prior to serving and reheat it in the microwave or, covered with foil, in a 300°F oven until hot in the center.
