Hashbrown Breakfast Casserole

This hearty breakfast casserole layers cooked breakfast sausage, sautéed onions and bell peppers, shredded hashbrowns, and cheddar cheese, bound together with a rich mixture of eggs, sour cream, milk, and seasonal spices. The casserole bakes until golden and just set, delivering a creamy, savory texture with crispy edges. The combination offers a filling dish suitable for brunch or a make-ahead breakfast. The addition of hot sauce gives a mild tang that complements the meaty and cheesy elements.

Description

The Hashbrown Breakfast Casserole starts with crumbled cooked breakfast sausage browned and mixed with diced yellow onion and both red and green bell peppers for a flavorful base. Shredded thawed hashbrowns coated in melted butter go into a casserole dish, layered with half the cheddar cheese and the sausage mixture.

A blended custard of beaten eggs, sour cream, milk, hot sauce, mustard powder, oregano, thyme, sage, salt, and pepper is poured over the casserole, and the remaining cheddar cheese is sprinkled on top. Baking uncovered at 350°F for about 50 minutes develops a golden edge while keeping the center creamy and just set.

The finished dish offers a combination of textures: crispy on the exterior edges with a tender and creamy interior. The spices enhance the savory profile without overpowering the robust sausage flavor, and the peppers add sweetness and color. This casserole works well for feeding a group at breakfast or brunch.

Thawing hashbrowns thoroughly prevents excess liquid and uneven cooking, and cooking the sausage beforehand removes grease. Leftovers store well and reheat nicely in the oven or microwave. The recipe allows for substitution of ham steaks for sausage by pre-cooking to reduce water content.

Ingredients

Servings
  • 1 pound breakfast sausage such as Jimmy Dean, ground
  • ½ yellow onion finely diced, small
  • ½ red bell pepper diced
  • ½ green bell pepper diced
  • 28 oz. hash browns thawed and patted dry, shredded
  • 4 tablespoons butter melted
  • 2 cups cheddar cheese divided in half
  • 12 egg large
  • 1 cup sour cream
  • ¾ cup milk
  • 1 teaspoon hot sauce

Seasonings

  • ½ teaspoon mustard powder
  • ¼ teaspoon oregano dried
  • ¼ teaspoon thyme dried
  • ¼ teaspoon sage ground
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

Instructions

Prep Work

  1. Place your oven rack in the middle of the oven and preheat oven to 350.
  2. Cook and crumble the sausage over medium-high heat until browned and cooked through, add the onions and peppers during the last 3 minutes or so. Drain grease and set aside.
  3. Crack the eggs in a medium bowl and beat them until just combined.
  4. Add the sour cream, milk, hot sauce, and seasonings (mustard powder, oregano, thyme, sage, salt, and pepper.) Stir until well combined.

Assemble and Bake

  1. Add the thawed hash browns to a lightly greased 9 x 13-inch casserole dish. Drizzle with melted butter and toss to coat.
  2. Top with 1 cup of shredded cheddar cheese, then add the cooked sausage, onions, and peppers.
  3. Pour the egg mixture over the sausage, onions, peppers, and hash browns. Top with remaining 1 cup of cheese.
  4. Bake, uncovered, for 50 minutes. Check it every 5 minutes or so from here, it's done when the edges are slightly browned and the middle is nearly set. It will finish setting while it rests.
  5. Let it rest for 10 minutes prior to serving.

Notes

  • Use fully thawed hashbrowns to prevent excess moisture and ensure even baking.
  • Cook breakfast sausage fully before assembling the casserole to drain excess fat.
  • You can substitute 2 (8 oz.) ham steaks for sausage; sauté them to release water and avoid sogginess.
  • Store leftovers in an airtight container refrigerated up to 3 days or freeze up to 3 months.
  • To reheat, cover casserole and bake at 350°F for 20-25 minutes until heated through.
  • Lamb Weston Thick Cut Hash Browns are recommended for better texture, but cubed hashbrowns are also acceptable.
