Spinach Frittata
This post may contain affiliate links. Read my full disclosure policy. Stuffed with baby spinach and two kinds of cheese, this spinach frittata makes a lovely brunch, lunch, or light dinner. Filled with heaps of baby spinach and two kinds of cheese, this spinach frittata tastes nutritious and rich, all at the same time. It’s silkier and more quiche-like than most frittatas, which are usually just glorified omelets with the fillings mixed in rather than stuffed inside. The key is adding heavy cream and lots of cheese to the egg mixture. It’s also important to bake the frittata in a low-temperature oven (as opposed to the traditional stovetop-to-broiler method), so the eggs cook gently into a custard without scrambling. This frittata can be served for brunch, lunch, or a light dinner – and since it’s good warm or at room temperature, leftovers can be packed for lunch or taken on a picnic. What You’ll Need To Make Spinach Frittata Step-by-Step Instructions Heat the oil in a 10-inch ovenproof nonstick skillet over medium heat. Add the shallot 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 1/4 teaspoon of the salt and continue cooking until all of the spinach is wilted, 1 to 2 minutes more. Meanwhile, in a large bowl, combine the eggs, heavy cream, pepper, and the remaining 1/4 teaspoon salt. Whisk to combine. Add the cooked spinach mixture, Cheddar, Parmigiano Reggiano, and basil to the egg mixture. Stir to combine. Pour the mixture back into the pan (no need to wash it). Place the pan 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.
