1. Preheat and Prep

• Preheat your oven to 375°F (190°C).

• Lightly grease a 9×13-inch baking dish with nonstick spray or butter.

2. Cook the Sausage Mixture

• In a large skillet, cook beef Bacon sausage over medium heat.

• Add chopped onions and sauté until the sausage is browned and cooked through.

• Drain any excess grease and set aside.

3. Make the Creamy Gravy

• In the same skillet, melt butter over medium heat.

• Whisk in flour and cook for 1 minute to form a roux.

• Gradually add milk, whisking constantly to avoid lumps.

• Cook for 5–7 minutes until thick and smooth.

• Season with salt and black pepper to taste.

4. Assemble the Casserole

• In a large bowl, mix thawed hash browns, sausage-onion mixture, cheddar cheese, mozzarella cheese, garlic powder, onion powder, salt, and pepper.

• Spread this mixture evenly into the greased baking dish.

5. Add Gravy and Biscuits

• Pour the prepared gravy over the hashbrown mixture and gently spread it to cover the surface.

• Place the biscuits evenly on top, spacing them apart for even baking.

6. Bake to Perfection

• Cover with foil and bake for 25 minutes.

• Remove foil and bake an additional 15–20 minutes or until biscuits are golden brown and fully cooked.
