What this casserole is..
Anyone else a massive fan of breakfast casseroles with biscuits? There’s just something so tasty about waking up and enjoying a warm casserole right from the oven.
I have such fond memories of having this biscuit gravy casserole when I was younger that I’m so excited to make it for our son now. Sitting at the breakfast pub, enjoying biscuit casseroles together, is my idea of a perfect start to the day.
Plus, this dish hits the sweet spot of comfort food and practicality—using pantry staples and baking it in one pan means less cleanup and more time together.
Step-by-Step Instructions
In less than 30 minutes, you’re going to be chowing down on this simple biscuit gravy casserole. Trust me, it’s delicious AND straightforward!
Step 1: Preheat oven to 425.
Step 2: Line the bottom of a greased 9×13-inch baking dish with biscuit dough. I diced my biscuits up into 5-6 slices each. I used frozen Biscuits, but you can also use refrigerated biscuits or homemade biscuit dough.
Using pre-cut biscuits (frozen or refrigerated) helps you get this on the table faster, which is perfect whether you’re prepping for company or a stress-free weekend breakfast.
Step 3: Sprinkle with sausage and cheese. Make it evenly spread. I used just classic breakfast sausage, but feel free to swap it with a spicy sausage.
Step 4: Whisk together the eggs, milk, salt, and pepper in a medium bowl until well blended; then pour over the sausage and cheese. Now mix a packet of gravy with milk and pour it over the top as well.
Step 5: Bake 25-30 minutes or until set. Let stand for 5 minutes before cutting into squares; serve warm.
Step 6: Once the casserole is done, prepare the gravy according to the package instructions and spoon it over the casserole for a classic biscuit and gravy topping.
Full directions and recipe is in the printable recipe card below.
Make it spicy (optional)
If you want, you can! The recipe below includes sausage that isn’t spicy, but you can certainly add hot sausage if you prefer.
Adding in hot sausage is just one way to add spice. You can also chop up some fresh jalapenos and add them in if you want or add in some chili powder, too.
If you want heat, there are numerous ways to achieve it.
How to tell when it’s fully baked
You’re going to have to pay attention to this way and judge this based on the look. The top should be a golden brown, and it should have a firm look to it at first glance.
You need to be certain that it doesn’t have any “jiggle” to it, either as that is an indication that the eggs aren’t cooked all the way through.
Make-ahead & overnight option
Absolutely! This is one of the biggest reasons why I love this simple recipe so much.
You can literally meal prep the entire recipe the night before and have it waiting in the fridge to bake in the morning.
It’s a simple way to save time in the morning by getting most of it completed the night before.
Topping ideas
You can easily add toppings to this simple breakfast dish. I love to add some fresh salsa, fresh tomatoes, and a dollop of sour cream.
You can also drizzle some honey to make it sweeter as well. (don’t knock it til you try it – it’s actually excellent!)
The best part about this simple breakfast casserole is that once you let it cool and cut it apart, each person can add their own toppings on as they please.
That way, you don’t have to put the flavor or topping that you want on the entire thing. Everyone can decide how to add flavor to their own piece.
Storing & reheating leftovers
Since this recipe yields a substantial pan of casserole, you’re likely to have some leftovers. All you really need to do is put a lid on the casserole pan and store it in the fridge.
It will stay fine for several days and is easy to reheat and enjoy for another morning breakfast or two.
If you have a lot leftover, store it in your freezer by placing it in a freezer-safe container for later use.
It should freeze just fine and thaw easily when it’s time to thaw and enjoy later.
This egg biscuit casserole is a simple dish that you’ll love and want to wake up to time and again.
Can I use homemade biscuit dough instead of canned/frozen biscuits?
Absolutely. If you prefer homemade dough, just roll or cut it into pieces and press into the bottom of the dish exactly as directed. Keep in mind fresh dough may bake a few minutes longer, so check for no jiggle in the center.
Can I swap out the sausage for a vegetarian option?
Yes! Use a plant-based breakfast sausage or crumbled tempeh seasoned with sage and paprika for similar savory flavor. Just ensure whatever you use is pre-cooked or warm through before adding the eggs to maintain baking time accuracy.
