Recipe Card

Servings: 8 Prep Time: 15 minutes Cook Time: 45 minutes Total Time: 1 hour

Ingredients

• 1 lb breakfast sausage (or bacon), cooked and crumbled

• 6 large eggs

• 2 cups shredded cheddar cheese

• 1 (20 oz) bag frozen hash browns, thawed

• 1 cup milk

• ½ cup diced onion (optional)

• ½ cup bell pepper, chopped (optional)

• ½ teaspoon salt

• ¼ teaspoon black pepper

• ¼ teaspoon garlic powder

Instructions

1. Preheat Oven: Preheat your oven to 350°F. Grease a 9x13-inch baking dish with butter or nonstick spray.

2. Cook the Sausage: In a large skillet, cook the sausage over medium heat until browned. Drain excess grease and set aside.

3. Assemble the Casserole: Spread the hash browns evenly in the prepared baking dish. Layer the cooked sausage on top, followed by half the cheese. Add onions and peppers if using.

4. Make the Egg Mixture: In a large bowl, whisk together eggs, milk, salt, pepper, and garlic powder. Pour evenly over the casserole.

5. Top and Bake: Sprinkle the remaining cheese on top. Bake uncovered for 40–45 minutes, or until the eggs are set and the top is golden brown.

6. Serve: Let it rest for 5 minutes before slicing. Serve warm with salsa, sour cream, or a side of fresh fruit.

Tips for the Perfect Breakfast Casserole

• Assemble the night before and refrigerate overnight for easy mornings.
