How to cook deliciously - Make-Ahead Frittata Squares with Spinach, Tomatoes, and Feta
1. Stage
Preheat the oven to 350°F: Butter a 2-quart baking dish.
2. Stage
Cook the vegetables: In a large skillet over medium heat, heat the olive oil. Add the tomatoes and cook, stirring often, for 2 minutes, or until just starting to soften but not yet falling apart. Transfer to a separate dish and set aside. Add the the scallions to the pan and cook for about 1 minute, or until softened. Stir in the spinach and 1/4 teaspoon of salt. Cook, stirring often, until the spinach wilts. Remove the pan from the heat and cool for a few minutes. Stir in the crumbled feta cheese.
3. Stage
Whisk egg mixture: In a large bowl, gradually whisk the milk into the sour cream until smooth. Whisk in the eggs, 1/2 teaspoon of salt and pepper.
4. Stage
Assemble and bake the frittata: Transfer the spinach filling from the pan into the baking dish and pour the egg mixture over top. Scatter the tomatoes on top of the eggs so they peek out, and sprinkle with the parsley. Bake for 40 to 45 minutes, or until the eggs are set. You can check with a paring knife inserted in the middle; the eggs should be set and no longer be runny.
5. Stage
Serve: Cool the frittata for at least 10 minutes, and cut into 9 servings. Store leftovers in the refrigerator for up to a week, and reheat in the microwave. Did you love the recipe? Give us some stars and leave a comment below!
