Breakfast sausage
All-purpose flour
Whole milk
Salt and black pepper
Frozen shredded hashbrowns (thawed)
Shredded cheddar cheese
Refrigerated buttermilk biscuits
Eggs
Milk
Optional: chopped green onions for garnish

Directions

I start by browning the breakfast sausage in a skillet over medium heat until fully cooked.
I sprinkle in the flour and stir for a minute, letting it soak up the fat, then slowly pour in the milk, stirring until it becomes a thick, creamy gravy. I season it with salt and pepper.
I preheat the oven to 350°F and grease a 9x13-inch baking dish.
I spread the thawed hashbrowns evenly in the bottom of the dish, then pour the sausage gravy over the top and spread it out.
I sprinkle about a cup of shredded cheddar over the gravy.
I cut each biscuit into quarters and scatter them over the casserole.
In a bowl, I whisk the eggs with a little milk and pour that mixture evenly over the biscuits.
I finish with the rest of the cheese on top.
I bake it for about 35–40 minutes until the biscuits are golden brown and cooked through, and the cheese is bubbling.
Once out of the oven, I let it cool for a few minutes and sometimes sprinkle green onions on top before serving.

Servings and Timing

This casserole serves about 8 people. Prep takes around 20 minutes, and baking takes 35–40 minutes, so I usually have it ready in about an hour total.

Variations

I sometimes add diced jalapeños or hot sauce to the gravy if I want a little heat.
For a vegetarian version, I skip the sausage and use sautéed mushrooms or plant-based sausage instead.
I’ve tried it with different cheeses like pepper jack or a Mexican blend when I want extra flavor.

Storage/Reheating

Leftovers keep well in the fridge for up to 3 days. I reheat single servings in the microwave or warm the whole dish in the oven at 350°F covered with foil until heated through. If the top starts to brown too much, I lay a piece of foil loosely over it.

FAQs

Can I make this casserole the night before?

Yes, I often assemble it the night before, cover it, and refrigerate. In the morning, I just bake it straight from the fridge, adding a few extra minutes to the cook time.

Do I have to cook the biscuits first?

Nope! The biscuit dough bakes right on top of the casserole. I just make sure they’re cut small enough to cook evenly.

Can I use homemade gravy?

Definitely. If I already have homemade sausage gravy, I use it in place of the sausage/flour/milk step.

What’s the best kind of sausage to use?

I usually go for regular breakfast sausage, but spicy or maple-flavored sausage also works great depending on the flavor I’m going for.

Can I freeze this casserole?

Yes, I bake it first, let it cool, then freeze portions wrapped tightly. To reheat, I thaw it overnight and warm it in the oven.

Conclusion

Biscuits & Gravy Hashbrown Casserole is one of my go-to breakfast bakes when I want something filling, flavorful, and comforting. The combination of creamy gravy, cheesy potatoes, and golden biscuits is hard to beat. It’s easy to make, endlessly customizable, and always a crowd-pleaser—especially when I want to impress without spending all morning in the kitchen.
