Savory Sweet Potato Casserole for Breakfast

Preheat the oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

In a large skillet, cook the sausage over medium heat with 1/4 inch of water until the water evaporates and the sausage is browned, about 10 to 15 minutes. Crumble the cooked sausage into a bowl.

In a bowl, combine the sweet potatoes and butter. Spread the mixture evenly into the prepared 9x13-inch dish.

In a large bowl, stir together the Cheddar-mozzarella cheese blend, onion, spinach, cottage cheese, eggs, and crumbled sausage. Spoon this mixture over the sweet potato layer.

Bake the casserole in the preheated oven for about 1 hour, or until a toothpick inserted in the center comes out clean and the eggs are set. Let it cool for 5 minutes before serving.
