Easy Sausage & Hashbrown Breakfast Casserole (Feeds 12!)
If you need a hearty breakfast that feeds a crowd with almost no effort, this Sausage Hashbrown Breakfast Casserole is the one to keep in your back pocket. It’s packed with all the comforting breakfast staples—savory sausage, crispy hash browns, fluffy eggs, and melty cheese—baked together in one easy dish.

Why You’ll Love This
This casserole brings together everything people want in a classic Southern-style breakfast—rich sausage, tender potatoes, plenty of eggs, and just the right amount of cheese. It bakes up soft and comforting on the inside with golden edges on top, and it never feels heavy or fussy.
It’s also incredibly forgiving. Whether you use mild or spicy sausage, red or yellow peppers, or swap in a different cheese, the casserole still turns out delicious. You can bake it right away or prep it the night before so breakfast is ready when you are.
And because it makes a full 9×13 pan, it’s ideal for holiday mornings, overnight guests, church gatherings, potlucks, or meal prep. It’s truly one of the easiest ways to feed 10–12 people without breaking a sweat.
Other crowd-pleasing breakfast options we love are ham and cheese strata, sausage muffins without Bisquick, and our delicious sausage cake.
Key Ingredients
Breakfast Sausage – Any ground pork breakfast sausage works (mild, hot, or sage). Brands like Jimmy Dean or Tennessee Pride give great flavor.
Eggs + Half and Half – These create the soft, custardy base that holds everything together.
Hash Browns – Frozen shredded hash browns keep this recipe simple. Thaw and pat dry so the casserole isn’t watery.
Cheese – Pepper Jack adds a little kick, but cheddar or Monterey Jack also work beautifully.
Vegetables – A mix of bell pepper and green onions adds color, mild sweetness, and balance.
Seasonings – Dry mustard, salt, and pepper are all you need to bring the flavors together.

How to Make Sausage Hashbrown Breakfast Casserole
1. Prep the dish
Heat the oven to 350°F and grease (or lightly butter) a 9×13 baking dish.
2. Browning the sausage
Cook the sausage in a large skillet over medium-high heat, breaking it into several large chunks and letting it sit so it can brown deeply on one side before turning.


3. Add and cook the red peppers
Once the sausage is mostly browned, add the diced bell peppers and cook until they soften.


4. Green onion + draining on paper towels
Add the green onions, stir to combine, and transfer the mixture to a paper towel–lined plate to drain.


5. Egg base + hash browns & cheese
In a large bowl, whisk the eggs, half-and-half, salt, pepper, and ground mustard. Add the hash browns and cheese, then mix until everything is evenly coated.


6. Adding the sausage mixture
Add the drained sausage mixture and fold it in until fully combined.


7. Into the baking dish + baked casserole
Pour the mixture into the prepared baking dish and spread it evenly. Sprinkle the remaining 1 cup of cheese over the top.
Bake at 350°F for 55–60 minutes, or until the center is set.


8. Serve warm.
Slice and enjoy with fresh fruit, biscuits, or your favorite breakfast sides.


Tips
- Shred your own cheese. Pre-shredded cheese has anti-caking agents that affect melting.
- Dry the hash browns well. Excess moisture can make the casserole dense instead of fluffy.
- Use spicy sausage for more flavor. Hot breakfast sausage brings great depth without adding extra steps.
- Let the casserole rest before slicing. This helps it set so you get clean slices.
Variations
- Swap the pork for turkey sausage, spicy Italian sausage, or even chicken sausage.
- Add crumbled bacon or chopped ham for extra smoky flavor.
- Change the cheese: cheddar, Monterey Jack, Colby Jack, or a mix all work.
- Add vegetables like mushrooms, broccoli, jalapeños, or diced tomatoes.
- Make it mild or spicy, using the sausage-and-cheese combination you prefer.
FAQs
Yes. Assemble the casserole, cover tightly, and refrigerate overnight. Let it sit at room temperature 30–60 minutes before baking.
Absolutely. Freeze individual slices or the whole baked casserole. You can also freeze the unbaked casserole tightly wrapped. Thaw overnight in the fridge before baking.
Usually, this happens when hash browns aren’t fully thawed or drained. Pat them dry for the best texture.
Yes, but use an 8×8 or 9×9 pan—not a pie plate—as the mixture is tall and needs even baking.

Can the ingredients be halved and then make in pie plate?
I probably wouldn’t recommend that. This casserole can get pretty tall and I wouldn’t be trusting the height of a pie plate. But .. you can always try 🙂
what happens with the rest of the cheese?
Hi Ruth, thank you so much for letting us know the remaining 1 cup of cheese was not listed when to use. I have corrected the recipe. 🙂
Looks awesome. What hashbrown do you use?
