Sausage Egg and Biscuit Breakfast Casserole is my go-to when I need a make-ahead breakfast casserole that still feels like a real brunch (not just "breakfast for a crowd"). You get the classic sausage + eggs + biscuits combo in one pan, and it slices cleanly once it rests, so serving is fast and stress-free.
If you're making this for guests, two things make the difference between "fine" and wow:
- spreading the biscuit pieces so you don't get a doughy middle
- baking until the center is fully set (not just browned on top)

Ingredients For Sausage Biscuit Casserole
- Refrigerated biscuits - Refrigerated biscuit dough is the foundation of the dish. Biscuits add a fluffy and slightly crispy texture and help make the dish more filling.
- Eggs - Provide a rich, creamy texture and protein.
- Milk - Helps the eggs to cook evenly and contributes to the creamy texture.
- Shredded cheddar cheese/jack mix - Adds a melty, gooey layer to this casserole.
- Breakfast sausage - Gives a savory, slightly spicy taste that works wonderfully with the eggs and cheese. The sausage also adds protein, making this breakfast even more satisfying.
- Salt and pepper - To taste.
How To Make Sausage Egg and Biscuit Breakfast Casserole
1. Preheat and prep
Preheat your oven to 350°F and spray a casserole dish with nonstick cooking spray.
2. Cut the biscuits
Open the tube of biscuits and separate them. Use a pizza cutter to slice each biscuit into six small pieces.
3.Cook and prep the sausage
Heat eight frozen pork sausage patties in the microwave or a skillet until fully cooked. Then chop them into small pieces. (You can also use bacon or turkey sausage if preferred!)
4. Layer the ingredients
Spread the biscuit pieces evenly on the bottom of the greased casserole dish. Add the sausage on top of the biscuits, then sprinkle some shredded cheese over the sausage.
5. Add the egg mixture
In a bowl, beat the eggs and milk together. Pour this mixture evenly over everything in the casserole dish.
6. Top with more cheese
Sprinkle the remaining cheese over the top for extra melty goodness.
7. Bake now or refrigerate overnight
If you're baking right away, pop it in the oven and bake until the eggs are set. Want to make it ahead? Cover the dish and refrigerate overnight, then bake in the morning as directed.
This recipe is perfect for potlucks and feeding a crowd. With just a few basic ingredients, such as biscuits, eggs, milk, cheese, and sausage, you can create a hearty, stress-free meal.
Tips For Biscuit Sausage Egg Casserole
- Don't overcook the sausage-cook just until done so it stays juicy in the oven.
- Spread biscuit pieces/sausage/cheese evenly so every slice has the right mix.
- Rest the casserole about 10 minutes before slicing so it sets and cuts cleanly.
Adding Vegetables To Breakfast Casserole
Adding veggies to this dish is a great way to add a bit of color and extra nutrients. Feel free to mix in bell peppers, onions, spinach, or mushrooms. If you are going to add vegetables, dice and sauté them first to bring out their flavors and keep them from adding excess moisture.
- Spinach: squeeze it dry after wilting.
- Mushrooms: cook until the pan is dry.
The best time to incorporate veggies is right after you've added the sausage, but before you add the eggs. Just sprinkle the veggies over the sausage. A small handful per veggie is plenty - too much can water down the eggs. Avoid raw tomatoes or frozen peppers unless fully cooked and drained.
What to Serve With This
This casserole is hearty and savory, so it pairs best with something fresh or crunchy:
- Fresh fruit salad, berries, or a simple fruit tray
- Yogurt parfait bar (yogurt + fruit + granola)
- Hash browns or roasted breakfast potatoes for a bigger brunch spread
- A simple green salad with a light vinaigrette (surprisingly perfect with cheesy casseroles)
- Muffins or coffee cake if you're feeding a crowd

Tammy says
Can you make it with leftover biscuits that have already been cooked? Would I need to add more milk?
Vicky says
Hi! Great question. This recipe actually works best with uncooked biscuit dough, since it bakes along with the rest of the casserole. Using already-cooked biscuits wouldn’t give you the same texture, even with more milk. Let me know if you try it the original way!
Dana H says
Made this casserole for Christmas morning and it was a favorite. The family requested this be made every year.
Vicky says
Hi Dana! Thanks for taking the time to tell me that! It means so much to hear it is part of your familiy's tradition.
GEM says
Overall, this casserole was okay, but I would not remake. The biscuits bake into a dumpling-like texture, which wasn’t my favorite. It may be better to bake the biscuits on top, so they can crisp up.
Holly says
One quick comment though, there are so many ads and junk all over the site it almost makes it unusable! Very frustrating at the very least… 🙁
Vicky says
Thanks so much for your honest feedback—I really appreciate you taking the time to share your thoughts. I hear you, and I understand how a cluttered experience can be frustrating.
Running this blog is my full-time job, and the ads help cover the costs of creating and sharing all this content for free. That said, I’m always looking for ways to strike a better balance between keeping the site sustainable and making it enjoyable for readers like you.
Holly says
Made this for Christmas morning breakfast, my guys loved it, will definitely be making it again!!!
Merry Christmas!!
Vicky says
Thanks so much for the kind words Holly. Hope you had a wonderful holiday.
Mary says
Can this be made the night before? And then put in oven in morning
Vicky says
Yes, it works great as a make ahead casserole. Simply assemble accoridng to directions, cover and refrigerate until the morning. Enjoy!
SV says
This is my go to breakfast casserole recipe! I have made it many, many times and it’s always a favorite.
Vicky says
Thanks so much for sharing your love for the breakfast casserole! We're thrilled to hear it's a hit in your kitchen.
Don Juan says
I dislike recipes like this that omit any reference to serving size or # of servings in the nutritional facts.
Vicky says
It says in the post it is 8 servings. You can slice it into 8 equal servings. Enjoy!
Katy says
I absolutely love this recipe! I have already made it twice. Only change is I add diced peppers and onions to the ground sausage while I cook it. So easy and delicious!
Erika says
Can we do this in the crockpot? I’d love to be able to keep it warm for different wake up times
Vicky says
That’s such a great idea! I haven’t tested this recipe in a crockpot, but in theory it should work if you cook it on low and keep an eye on it so it doesn’t overcook around the edges. The nice thing is the crockpot will definitely help keep it warm for staggered breakfasts. If you try it, I’d love to hear how it turns out!
Janet Davis says
This looks interesting. I'd never think of that biscuit thing. Hm...
