Ingredients

Instructions

  1. Step 1: Preheat a non-stick skillet over medium-low heat and add 1 tablespoon unsalted butter, allowing it to melt and coat the pan without browning.
  2. Step 2: Add 1 cup chopped fresh spinach to the skillet and cook for 2 minutes until wilted and excess moisture evaporates, stirring occasionally until the spinach is tender but still vibrant green.
  3. Step 3: In a medium bowl, whisk together 6 large eggs, 1/2 teaspoon garlic powder, and a pinch each of salt and freshly ground black pepper until fully combined and slightly frothy.
  4. Step 4: Pour the egg mixture over the wilted spinach in the skillet, then evenly sprinkle 1/2 cup shredded mozzarella and 1/4 cup shredded cheddar over the top.
  5. Step 5: Cover the skillet with a lid and cook over medium-low heat for 8-10 minutes until the edges are golden and the center is set (the frittata should be slightly jiggly in the center but not runny).
  6. Step 6: Remove from heat and let rest for 2 minutes before slicing into wedges to allow the cheese to set.
