Ingredients

Casserole Base

  • 2 lb hot breakfast sausage

  • 1 (30–32 oz) bag frozen shredded hash browns, thawed

  • 1 tsp salt

  • ½ tsp pepper

  • ¼ tsp garlic powder

  • ¼ tsp onion powder

  • 1 cup shredded muenster cheese

  • 1 cup shredded Velveeta cheese (or see substitutions below)

Egg Mixture

  • 8 large eggs

  • 2 cups milk

  • 1 Tbsp Worcestershire sauce

Instructions

  1. Preheat & Prep
    Heat oven to 350°F (175°C). Lightly spray a 9×13-inch baking dish with non-stick cooking spray.

  2. Cook the Sausage
    In a large skillet, brown sausage over medium heat until fully cooked. Drain any excess fat and set aside.

  3. Brown the Hash Browns
    In the same skillet, cook thawed hash browns until lightly golden (add a drizzle of oil if needed). Transfer to the prepared baking dish, spreading evenly.

  4. Layer the Casserole
    Top the hash browns with cooked sausage, then sprinkle evenly with both cheeses.

  5. Mix the Egg Custard
    In a large bowl, whisk together eggs, milk, Worcestershire sauce, salt, pepper, garlic powder, and onion powder until well combined.

  6. Assemble & Bake
    Pour the egg mixture evenly over the casserole layers. Bake uncovered for 45–60 minutes, or until the center is set and the top is golden.

  7. Serve
    Let the casserole rest for 5–10 minutes before slicing and serving hot.

Tips & Variations

  • Thaw First: Always thaw frozen hash browns before browning for better texture.

  • Cheese Swap: Try cheddar, colby-jack, gouda, or mozzarella instead of Velveeta.

  • Extra Veggies: Add sautéed bell peppers, mushrooms, or onions for more flavor.

  • Make-Ahead: Assemble the night before, refrigerate, then bake in the morning (add 10–15 minutes to the bake time).

  • Freezer-Friendly: Assemble, wrap tightly, and freeze for up to 3 months. Thaw overnight before baking.

Tools You’ll Need

  • 12-inch non-stick skillet

If you want, I can also prepare a “Party Brunch Board” serving suggestion where this casserole is the centerpiece, paired with easy sides and garnishes so it’s presentation-ready for gatherings. That could make this recipe even more engaging for a blog audience. Would you like me to add that?
