Now let’s talk ingredients.
Ingredients You’ll Need
Here’s what you’ll need to make this sausage biscuit and hash brown casserole:
1 (16 oz) can of Pillsbury Grands! Buttermilk Biscuits – Flaky, buttery, and the perfect topping when cut into quarters.
1 lb Jimmy Dean Premium Pork Sausage – This brings that signature breakfast flavor and lots of savory goodness.
3 cups frozen Ore-Ida Shredded Hash Browns – No need to thaw; just layer them right in for a crisp bottom.
1 packet (2.75 oz) McCormick Sausage Flavor Gravy Mix – An easy shortcut to rich, flavorful gravy.
2 cups milk – For mixing the gravy mix.
1½ cups shredded cheddar cheese – For that gooey, melty layer in the middle.
½ tsp salt, ¼ tsp black pepper, ½ tsp garlic powder – Just enough seasoning to bring it all together.
And don’t forget—you can always dress this up with extras like onions, peppers, or fresh herbs. I’ll share some easy variations later on.
STEP-BY-STEP INSTRUCTIONS
Step 1: Preheat and Prep
Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with non-stick spray or a little butter to keep everything from sticking later on.
Step 2: Cook the Sausage
In a medium skillet over medium heat, cook the pork sausage, breaking it up into crumbles as it browns. This usually takes about 6–8 minutes. Once it’s fully cooked, drain off any excess grease. If you want to level up the flavor here, feel free to toss in a diced onion or a chopped bell pepper while the sausage is cooking—they’ll soften up and add great texture.
Step 3: Layer the Hash Browns and Sausage
Spread your frozen shredded hash browns evenly across the bottom of the baking dish. No need to thaw them—they’ll bake up just fine straight from the freezer. Then, sprinkle the cooked sausage right over the hash browns to form your first layer of savory deliciousness.
Step 4: Mix and Pour the Gravy
In a mixing bowl, whisk together the sausage-flavored gravy mix and milk until the mixture is smooth and lump-free. This is your shortcut gravy, and it works beautifully for this casserole. Pour it evenly over the sausage and hash brown layers, letting it seep in and coat everything.
Step 5: Add the Cheese
Now sprinkle the shredded cheddar cheese over the top of the gravy layer. This will melt down and bind all the layers together while adding that classic cheesy flavor we all love.
Sausage Biscuit and Hash Brown Breakfast Casserole
Alright, now that we’ve got our layers of hash browns, sausage, gravy, and cheese in place, it’s time for the finishing touch: those golden, buttery biscuit pieces. This part is what really sets the casserole apart—it’s the perfect way to bring that classic biscuits-and-gravy vibe into a dish that’s super easy to slice and serve.
I’ve tried this a few different ways, and cutting the biscuits into quarters before baking gives you just the right texture. You’ll get crispy tops, soft centers, and that satisfying rise that makes the whole dish feel extra cozy and indulgent.
Let’s pick up right where we left off!
Step 6: Cut and Arrange the Biscuits
Take your can of Pillsbury Grands! Buttermilk Biscuits and separate the individual biscuits. Cut each one into four equal pieces (quarters) using kitchen shears or a sharp knife. These smaller pieces bake more evenly and give you little pops of buttery biscuit throughout the casserole.
Arrange the biscuit quarters over the top of the shredded cheese layer. You want to space them out in a single layer so they can rise and get that golden-brown crust while baking. Don’t worry if it doesn’t look perfect—once they puff up, the casserole will look beautiful.
Step 7: Bake Until Golden and Bubbling
Slide the casserole dish into your preheated oven (375°F) and bake for 25 to 30 minutes. You’re looking for the biscuits on top to turn a rich golden brown and for the cheese and gravy layers underneath to be hot and bubbly.
Once baked, remove the dish from the oven and let it rest for about 5 minutes. This helps everything settle and makes slicing and serving much easier.
Helpful Tips and Easy Variations
This recipe is already a crowd-pleaser, but here are a few ways you can switch things up based on what you have on hand—or to suit your family’s taste:
Add Veggies: Toss in some sautéed onions, bell peppers, or even mushrooms with the sausage. It adds flavor, texture, and a little extra nutrition.
Spice It Up: If you like heat, try using hot breakfast sausage instead of mild. You can also add a pinch of cayenne to the gravy or sprinkle some crushed red pepper over the cheese layer.
Try a Different Cheese: Sharp cheddar gives this dish a nice tang, but Monterey Jack, Colby, or even pepper jack can work great depending on your flavor preference.
Make It Meatless: You can substitute plant-based sausage or a mix of sautéed vegetables for the pork sausage if you’re looking for a vegetarian twist.
Garnish with Fresh Herbs: A sprinkle of chopped green onions or fresh chives just before serving adds a nice pop of color and a fresh, slightly oniony bite.
Make-Ahead and Storage Tips
This casserole is fantastic when you want to prep ahead for a holiday breakfast or busy weekend morning. Here’s how to make it work:
Make-Ahead (Unbaked): Assemble the casserole up to the point of adding the biscuits, cover, and refrigerate overnight. When you’re ready to bake, remove it from the fridge, add the biscuit pieces on top, and bake as directed—just add a few extra minutes to the bake time since it’s starting cold.
Leftovers: Any leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat individual portions in a 350°F oven for about 10 minutes to keep the biscuits from going soggy.
Freezing: I don’t recommend freezing this one, just because the texture of the biscuits doesn’t hold up well after thawing. But if you absolutely need to, wrap the cooled casserole tightly and freeze for up to 1 month. Reheat in the oven from frozen at 350°F until warmed through.

We’ve layered it, baked it, and added all the tips and tricks to make this breakfast casserole the star of your table. Now let’s wrap things up with a helpful FAQ section and a few final thoughts to inspire you to try it for yourself.
FREQUENTLY ASKED QUESTIONS
Can I make this casserole the night before?
Absolutely! Assemble everything up to the cheese layer and cover it tightly. Refrigerate overnight. In the morning, add the biscuit pieces on top just before baking. Since it’ll be cold from the fridge, you may need to add 5 to 10 extra minutes of baking time.
What can I use instead of canned biscuits?
If you prefer not to use store-bought biscuits, you can make your own buttermilk biscuit dough and cut it into small pieces before placing them on top. Just make sure the pieces aren’t too thick, or they might not cook all the way through.
Can I use homemade sausage gravy instead of a gravy mix?
Definitely. If you have a go-to homemade sausage gravy recipe, feel free to use it here. Just make sure you have about 2 cups of prepared gravy to pour over the sausage and hash brown layer.
Do the hash browns need to be thawed first?
Nope! One of the best parts of this recipe is that you can use the hash browns straight from the freezer. They cook up just fine in the oven and help keep prep quick and easy.
How do I know when the casserole is done baking?
Look for the biscuit pieces on top to be a deep golden brown. You’ll also notice the edges of the casserole bubbling slightly. If the tops brown too fast but the biscuits still feel doughy underneath, you can lightly tent the dish with foil and continue baking for a few more minutes.
Can I add eggs to this recipe?
You sure can! If you want a more traditional breakfast casserole with eggs, whisk 4–6 eggs with the milk and gravy mix before pouring it over the sausage and hash browns. Just note that this will change the texture to more of an egg bake.
What’s the best way to reheat leftovers?
The oven is best. Reheat slices in a 350°F oven for about 10 minutes. This brings back the crispness in the biscuits and keeps the layers from getting soggy.
FINAL THOUGHTS
If you’re a fan of biscuits and gravy (and really, who isn’t?), this Sausage Biscuit and Hash Brown Breakfast Casserole is a must-try.
