We LOVE a good breakfast casserole! They’re perfect for holidays (especially Christmas morning), brunch, showers and especially when you have company in town.
Today’s easy breakfast casserole is filling, takes minutes to put together, and is packed with flavor – biscuits, eggs, and sausage, there’s something for everyone! It’s our go-to breakfast bake!
One reason we love it is because the ingredients are SIMPLE!! There are only a handful, and it’s prepped in 5 minutes – just layer and bake!
It can also be made ahead of time (the night before) or easily whipped up right before baking – versatile AND delicious!
Why we think you’ll love it:
- Refrigerate overnight or bake it immediately. Either way, this breakfast casserole is quick and easy!
- Ready in no time! Throw it together from scratch in 5-10 minutes, pop it straight into the oven, and enjoy it 30 minutes later.
- So filling. Biscuits, eggs, and sausage – it’s hearty and packed with flavor!
Breakfast Casserole Ingredients
- Grands! Biscuits (1, 16.3-ounce can, 8 count): Press into the pan to make a buttery, flaky base that holds the casserole. Or 16 ounces Homemade Biscuit dough (partially cook before adding the toppings to ensure it cooks thoroughly.)
- Jimmy Dean precooked sausage crumbles (1, 8-ounce package) or crumbled cooked sausage (1 cup): Savory protein that adds hearty flavor in every bite. If using regular sausage, cook in a skillet over medium heat cooking the sausage, breaking and flipping, until no longer pink.
- Shredded mozzarella cheese (1 cup): Melts stretchy and creamy for that classic cheese pull.
- Shredded cheddar cheese (1 cup): Brings sharp flavor and helps the top brown golden.
- Large eggs, beaten (8): Set into a fluffy layer that binds the filling so slices hold together.
- Milk, room temperature (1 cup): Loosens the eggs for a tender, custardy texture.
- Salt and pepper to taste: Simple seasoning that brightens and balances the rich ingredients.
- optional veggies – Saute and add spinach, mushrooms, and red bell peppers.
- optional toppings – green onions, bacon bits, sour cream, salsa, or hot sauce

Kristyn’s Recipe Tips
- Make it any meat. Turkey, chicken sausage, bacon, ham or spicy chorizo all are great for this recipe. You can even add a combo of any of these meats to make it meat lovers.
- Savory and Sweet. For any function, holiday or get together, we love to make this recipe and also make a sweet casserole like our French Toast Casserole, Coffee Cake or Cinnamon Roll Cake. Everyone loves the combo!

This recipe was first published August 2014.
never been big on breakfast casseroles. this is a keeper! after reading reviews I decided to decrease the temp to 375, especially since I was using glass, and bake 20 min. it HADN’T browned yet so I put it in for another 5 min. then it only browned on one side, so I increased the temp to 425, rotated DISH 180, and put in 1 minute. yum!
Well, thank you for trying this one! Glad you liked it 🙂
I Just made it! HUSBAND loved it! Very easy and Tasty!
Glad he liked it!! Thank you for sharing that & trying it 🙂
I would like to make this for 100 people and have 18x12x3 lasagna roasters, can you please tell me how much more will i have to alter the recipe. Also how many people will 1-18x12x3 pan serve?
thank you for your time,
Well, depending on how big you cut the squares, you could get 12 bigger & 16 smaller squares, so if you stuck to 12 bigger ones..that is x the recipe by 8. If you did smaller sizes, you would need to times the recipe by 6. I haven’t used that size of pan before, but maybe 16 nice size pieces? I’m not really sure, but it would depend on how big/small you cut them. Hope that all helps! Good luck!
I made the 8×8 version as written, except I used pepper jack cheese instead of mozzarella. It turned out great! I think green peppers and onion would be a good addition, and I wonder about topping it with some kind of sauce. Has anyone tried this?
I haven’t tried with a sauce, but the peppers & onion are great. Glad you liked it!
I was wondering how to get my eggs to not run under my BISCUITS. Any advice?
Since, it’s liquid..it will run under, but it all cooks together & makes it turn out the way it does 🙂
I made this last night for the first time and the only change made was I used heavy whipping cream + water in place of the milk. The cheddar used was garlic & herb-flavored and the Jimmy Dean crumbles used were a combo of bacon and sausage. Tasted great! Might would add one more egg in future preparations, but loved it as is. 🙂
Oh! AND i DID REDUCE THE HEAT TO 400 DEGREES f (AFTER READING OTHERS’ COMMENTS), THEN ADDED MAYBE 5 MINUTES TO THE COOK TIME (COVERING WITH FOIL THE LAST FEW MINUTES TO ENSURE IT COOKED THROUGH IN THE MIDDLE).
Thank you for sharing what you did!! Sounds great!
Oh Kristyn, Perfect timing! My daughter & her family are coming for my son’s wedding & this will be great! thank you for all your great recipes.
