Make-Ahead Sausage Breakfast Casserole


  • Author: Karina
  • Total Time: 60 minutes
  • Yield: 8 servings 1x

Description

A savory, cheesy, and crispy overnight breakfast casserole that allows you to prep the night before and bake in the morning. Perfect for feeding a crowd or enjoying a stress-free weekend brunch.


Ingredients

Scale
  • 1 pound pork breakfast sausage (links removed from casings)
  • 2 cups frozen shredded hash browns (thawed)
  • 1 loaf French bread or baguette (diced into 1-inch cubes)
  • 8 large eggs
  • 1 cup heavy cream
  • 1 cup whole milk
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly cracked black pepper
  • 1 teaspoon dried mustard powder
  • 1/2 teaspoon garlic powder
  • 2 cups shredded cheddar cheese
  • Butter or cooking spray (for greasing dish)

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Cook the sausage in a large skillet over medium heat until browned and crispy, about 8-10 minutes. Drain excess grease and set aside to cool.
  3. Dice the bread into 1-inch cubes. If the bread is fresh, toast the cubes in the oven at 350°F for 5 minutes to dry them out, then let cool.
  4. Grease a 9×13 inch baking dish. Spread half of the diced bread in the bottom.
  5. Sprinkle half of the cooked sausage over the bread, followed by half of the thawed hash browns.
  6. Repeat layers with remaining bread, sausage, and hash browns.
  7. In a large mixing bowl, whisk together eggs, heavy cream, whole milk, salt, pepper, mustard powder, and garlic powder until uniform.
  8. Pour the egg mixture evenly over the layered ingredients. Gently press down with a spatula to ensure absorption. Let sit for 5 minutes.
  9. Sprinkle shredded cheddar cheese evenly over the top.
  10. Bake for 40-45 minutes until the top is golden brown, cheese is bubbly, and a knife inserted in the center comes out clean. Cover with foil if browning too fast.
  11. Remove from oven and let rest for 10 minutes before cutting and serving.

Notes

For best results, use stale bread to prevent a soggy texture. Ensure hash browns are thawed and drained to avoid excess water. The casserole can be assembled the night before, covered, and refrigerated overnight; add 5-10 minutes to baking time if baking from cold. Do not freeze, as the texture of eggs and dairy will suffer.
