Whether you use fresh or frozen spinach, this baked casserole combines tender greens with eggs, Parmesan, and mozzarella for a rich, comforting flavor that pairs beautifully with any main dish.

Ingredients

Scale
  • 10 ounces fresh spinach (or 1 package frozen spinach, thawed and drained)
  • 2 large eggs
  • 1 cup shredded Parmesan cheese
  • 1 cup shredded mozzarella or cheddar
  • 1/2 cup sour cream or Greek yogurt
  • 1/2 cup milk
  • 2 tablespoons butter, melted
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • Salt and pepper, to taste
  • Optional topping: crushed crackers or breadcrumbs for a golden crust

Instructions

  1. Preheat and prep: Set oven to 375°F (190°C). Grease a medium baking dish with butter or spray.
  2. Cook the spinach: Sauté fresh spinach in a skillet until wilted, then drain and squeeze dry. If using frozen, thaw and squeeze dry well.
  3. Mix the filling: In a bowl, whisk together eggs, sour cream, milk, garlic powder, onion powder, salt, and pepper. Stir in half the Parmesan and all the mozzarella.
  4. Combine and assemble: Mix spinach into the creamy mixture. Spread into the prepared baking dish and top with remaining Parmesan and optional breadcrumbs.
  5. Bake: Bake uncovered for 25–30 minutes until golden and bubbly. Let rest for 5 minutes before serving.

Notes

  • Drain spinach thoroughly to prevent a watery casserole.
  • Use full-fat dairy for the creamiest texture.
  • Add a touch of nutmeg or chili flakes for depth of flavor.
  • Top with breadcrumbs or toasted nuts for crunch.
  • Make ahead and refrigerate overnight before baking.
