Spinach Casserole

1 (16 ounce) package cottage cheese

6 eggs

½ cup all-purpose flour

¼ cup sour cream

2 teaspoons salt

½ teaspoon ground black pepper

2 (10 ounce) packages frozen chopped spinach, thawed and drained

4 cups shredded Cheddar cheese, divided

Preheat an oven to 350 degrees F (175 degrees C). Grease a 9x13 inch baking dish.

Place cottage cheese, eggs, flour, sour cream, salt, and pepper in a food processor. Process until smooth. Mix spinach, cottage cheese mixture, and 2 cups of Cheddar cheese in a bowl, then spread into the prepared baking dish.

Bake in the preheated oven until a knife inserted into the center comes out clean, about 45 minutes. Top with the remaining 2 cups of Cheddar cheese and continue baking until cheese has melted, about 10 minutes.
