Description
This creamy spinach frittata is the perfect addition to any brunch menu. It's simple to make and easy to customize: Add extra veggies or protein to make it your own.
Ingredients
- 6 eggs
- ¾ cup shredded white cheddar cheese (about 3 ounces)
- 1/3 cup heavy cream
- kosher salt and fresh cracked black pepper, to taste
- 1 Tablespoon butter
- 2 cloves garlic, minced
- 1 medium shallot, thinly sliced
- 2 packed cups baby spinach (2 ounces)
Instructions
- Heat oven to 400° Fahrenheit.
- Make the egg mixture. Add eggs, shredded white cheddar, and heavy cream to a medium mixing bowl with a generous pinch of kosher salt and pepper. Whisk to combine, then set aside.
- Sauté the veggies. Heat a 9” cast iron skillet over medium heat. Add butter to skillet and let it melt, then add garlic and shallot. Sauté, stirring occasionally, for 3-5 minutes until shallots are softened and lightly browned. Add spinach and cook for 2-3 minutes more, stirring occasionally, until spinach is wilted. Spread veggies over the skillet in a fairly even layer, then turn off the heat.
- Assemble. Gently pour the egg mixture into the skillet on top of the spinach. No need to stir - just let the eggs settle around the filling.
- Bake. Use an oven mitt to carefully transfer the skillet to the 400° F oven. Bake 15-20 minutes, until eggs have puffed up, are no longer jiggly in the center, and the frittata is lightly browned around the edges. Remove frittata from the oven; let cool 10-15 minutes before slicing and serving. Note: If you use a larger pan, you may need to reduce the bake time.
Notes
Equipment notes. We prefer a 9” cast iron skillet for this recipe. If you don’t have cast iron, use another oven-safe skillet or an enameled Dutch oven. If you don’t have an oven-safe skillet, sauté the aromatics and spinach as directed, then transfer to a greased oven-safe baking dish, add the egg mixture, and bake from there. You may need to adjust the bake time for other skillet sizes (an 8” skillet may need a little extra time; a 12” skillet will cook the eggs more quickly). Our testers recommend adding an extra egg or two if you're using an especially large skillet (10" or wider).
Substitutions and Additions. Use olive oil instead of butter. Add extra veggies (onions, mushrooms, garlic, bell peppers) when you sauté the shallot and garlic. Swap some or all of the white cheddar here for gruyere cheese, goat cheese, feta, or havarti. Use half and half or whole milk instead of the cream if you prefer.
Storing and Reheating Leftovers. Store cooled, leftover frittata slices in an airtight container in the fridge for up to 3 days. When you’re ready to serve, reheat slices on a sheet pan in a 350° F oven for 5-10 minutes, until warmed through. We don’t recommend freezing leftover frittata as it can make the eggs rubbery and tough.
