The Core Ingredients

The magic of this casserole lies in its simple, accessible ingredients. Here’s what you’ll need to bring this dish to life.

  • Pork Sausage: One pound of ground pork sausage provides the savory, hearty base. Feel free to use mild, medium, or hot, depending on your preference.
  • Frozen Shredded Hash Browns: A 30-ounce bag of frozen shredded hash browns creates the crispy bottom layer. Thawing them first is key!
  • Eggs: A dozen large eggs create the fluffy, custardy filling.
  • Milk & Heavy Cream: A combination of whole milk and heavy cream gives the egg mixture a rich, decadent texture.
  • Cheddar Cheese: Two cups of freshly shredded sharp cheddar cheese deliver that gooey, cheesy goodness. Shredding your own cheese from a block will always yield the best melt.
  • Onion & Bell Pepper: Finely diced yellow onion and green bell pepper add a subtle sweetness and depth of flavor.
  • Seasonings: Garlic powder, paprika, salt, and black pepper are all you need to perfectly season the dish.

How to Make Sausage Hash Brown Breakfast Casserole Step-by-Step

Follow these simple steps for a foolproof casserole every single time. It’s all about building layers of flavor.

  1. Preheat and Prep: First, preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or nonstick spray.
  2. Brown the Sausage and Veggies: In a large skillet over medium-high heat, cook the ground sausage until it’s no longer pink. Break it apart with a spoon as it cooks. Add the diced onion and bell pepper and continue to cook for 4-5 minutes until they soften. Drain off any excess grease.
  3. Create the Hash Brown Layer: In a large bowl, mix the thawed hash browns with half of the shredded cheese, salt, and pepper. Press this mixture firmly and evenly into the bottom of your prepared baking dish to form a crust.
  4. Bake the Crust: Bake the hash brown crust for 20 minutes, or until it’s lightly golden and set. This step is crucial for preventing a soggy bottom!
  5. Mix the Egg Filling: While the crust bakes, whisk the eggs, milk, heavy cream, garlic powder, paprika, and remaining salt and pepper in a bowl until smooth and well-combined.
  6. Assemble the Casserole: Remove the hash brown crust from the oven. Sprinkle the cooked sausage and vegetable mixture evenly over the top. Pour the egg mixture over the sausage. Finally, top it all off with the remaining shredded cheese.
  7. Bake to Perfection: Bake for 30-35 minutes, or until the eggs are set in the center and the top is golden brown and bubbly. You can check for doneness by inserting a knife into the center; it should come out clean.
  8. Rest and Serve: Let the casserole rest for 10 minutes before slicing and serving. This allows it to set completely, making it easier to cut clean slices. Garnish with fresh parsley if desired.

Pro Tips for Casserole Perfection

A few simple tricks can elevate your Sausage Hash Brown Breakfast Casserole from great to absolutely unforgettable.

  • Thaw Your Hash Browns: Do not skip this! Thawing frozen hash browns and squeezing out any excess moisture is the number one secret to a crispy, not soggy, crust.
  • Shred Your Own Cheese: Pre-shredded cheese is coated in starches that prevent it from melting as smoothly. For the best cheesy pull, grate it yourself.
  • Don’t Overbake: Keep an eye on the casserole. The eggs should be just set. Overbaking can lead to a rubbery texture.

Time-Saving Make-Ahead & Freezing Instructions

This Sausage Hash Brown Breakfast Casserole is a perfect make-ahead meal. Here’s how to do it right.

Overnight Instructions

To prepare the night before, follow all the steps up to the final baking. Assemble the entire casserole, cover it tightly with plastic wrap or foil, and refrigerate overnight. In the morning, remove it from the fridge 30 minutes before baking to let it come to room temperature. You may need to add 5-10 minutes to the baking time.

Freezing Instructions

This casserole freezes beautifully. Bake it as directed and let it cool completely. You can freeze it whole or cut it into individual portions. Wrap tightly in plastic wrap and then foil. It can be frozen for up to 3 months. To reheat, thaw in the refrigerator overnight and bake at 350°F until warmed through, or microwave individual portions.

  • Vegetables: Feel free to add sautéed mushrooms, spinach (be sure to squeeze it dry), or jalapeños for some heat.

What to Serve It With

While this casserole is a hearty meal on its own, it pairs wonderfully with a few simple sides. Consider a fresh fruit salad, sliced avocado, or a side of salsa and sour cream. For a truly decadent brunch, you can’t go wrong with a batch of fluffy homemade pancakes.

Ingredients
  

  • 1 lb ground pork sausage mild or hot
  • 1 medium yellow onion finely diced
  • 1 medium green bell pepper finely diced
  • 30 oz frozen shredded hash browns thawed and patted dry
  • 2 cups shredded sharp cheddar cheese divided
  • 12 large eggs
  • 1 cup whole milk
  • 1/2 cup heavy cream
  • 1 tsp garlic powder
  • 1/2 tsp paprika
  • 1 tsp salt divided
  • 1/2 tsp black pepper divided

Equipment

  • 1 9x13 inch baking dish
  • 1 Large Skillet
  • 1 Large Mixing Bowl

Method
 

  1. Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish.
  2. In a large skillet, cook the ground sausage over medium-high heat until browned. Add the diced onion and bell pepper and cook until softened, about 4-5 minutes. Drain excess grease.
  3. In a large bowl, combine the thawed hash browns, 1 cup of shredded cheese, 1/2 tsp salt, and 1/4 tsp pepper. Press the mixture firmly into the bottom of the prepared baking dish.
  4. Bake the hash brown crust for 20 minutes until lightly golden.
  5. In a separate bowl, whisk together the eggs, milk, heavy cream, garlic powder, paprika, and the remaining salt and pepper.
  6. Sprinkle the cooked sausage mixture over the pre-baked hash brown crust. Pour the egg mixture evenly over the sausage. Top with the remaining 1 cup of cheese.
  7. Bake for 30-35 minutes, until the eggs are set and the top is golden and bubbly. A knife inserted into the center should come out clean.
  8. Let the casserole stand for 10 minutes before slicing and serving to allow it to set.

Notes

Tip 1: Ensure your hash browns are thoroughly thawed and patted dry with paper towels to prevent a soggy crust.
Tip 2: For the creamiest texture, shred your own cheese from a block. Pre-shredded cheeses have anti-caking agents that can affect the melt.
Tip 3: Let the casserole rest before slicing. This helps it hold its shape for perfect servings.
