Ingredients (U.S. Measurements)
- 2 lb frozen shredded hash browns
- 1 lb breakfast sausage, cooked and drained
- 12 oz bacon, cooked and chopped (reserve some for topping)
- Salt, black pepper, and garlic powder, to taste
- 2 cups shredded cheddar cheese (divided)
- 1 packet country gravy mix (such as Pioneer-style)
- 2 cups water (for gravy preparation)
- 6 large eggs, whisked
- 2 green onions, chopped (optional garnish)
Step-by-Step Instructions
1. Cook the Bacon and Sausage
Direct answer: Fully cook both meats before assembling the casserole.
- Preheat oven to 400°F.
- Bake bacon on a parchment-lined sheet for 20–25 minutes until crispy.
- Brown sausage in a skillet over medium heat; drain excess grease.
- Chop bacon and reserve a small amount for topping.
Why this matters: Removing excess grease prevents a soggy casserole.
2. Build the Base
- Lightly grease a 9×13-inch baking dish.
- Spread frozen hash browns evenly across the bottom.
- Layer cooked sausage and most of the bacon over potatoes.
- Sprinkle 1 cup cheddar cheese over the meat.
- Season lightly with salt, pepper, and garlic powder.
Tip: No need to thaw frozen hash browns unless they are clumped together.
3. Prepare the Gravy
Direct answer: Prepare gravy separately before adding it to the casserole.
- Whisk gravy mix with 2 cups water in a saucepan.
- Cook until thick and smooth.
- Pour evenly over the layered ingredients.
The gravy adds moisture and binds the layers together.
4. Add Eggs and Final Cheese Layer
- Evenly pour whisked eggs over the casserole.
- Use a spatula to help distribute if needed.
- Top with the remaining 1 cup cheddar cheese.
The eggs set during baking and hold the casserole together.
5. Bake
- Reduce oven temperature to 375°F.
- Bake uncovered for 45 minutes.
- Check doneness by inserting a knife into the center — it should come out clean.
If the top browns too quickly, tent loosely with foil.
Internal temperature should reach at least 160°F for food safety.
6. Garnish and Serve
- Sprinkle reserved bacon and chopped green onions on top.
- Let rest 5–10 minutes before slicing.
- Serve warm.
Optional pairings:
- Fresh fruit
- Toast or biscuits
- Hot sauce or ketchup

Pro Tips for Better Results
- Grate your own cheese: Pre-shredded cheese contains anti-caking agents that affect melt quality.

- Don’t over-season: Sausage, bacon, and gravy already contain salt.
- Rest before slicing: This helps clean cuts and prevents crumbling.
FAQ
Can I use fresh potatoes instead of frozen hash browns?
Yes. Shred russet potatoes, rinse to remove starch, and pat completely dry before layering.

How do I know when it’s done?
The center should be firm, and a knife inserted should come out clean. Internal temperature should reach 160°F.

It can be if you use gluten-free gravy mix and verify all processed ingredients are certified gluten-free.
