👩🍳 Instructions
1. Prep the Ingredients
-
Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.

In a large bowl, whisk eggs, milk, cottage cheese, garlic powder, salt, pepper, and nutmeg until smooth.
3. Assemble the Casserole
-
Spread spinach, sautéed veggies, feta, and sun-dried tomatoes evenly in the baking dish.
-
Pour the egg mixture over the top. Gently shake the dish to distribute.
-
Sprinkle with mozzarella and Parmesan.
4. Bake
-
Bake for 35–45 minutes, until the center is set and the top is golden brown.

Let rest for 10 minutes before slicing.
