The definition of comfort food: sausage, egg, & cheese biscuit casserole. Like your favorite breakfast sandwich but all baked IN ONE DISH…! This is the breakfast that keeps on giving because we’ve been eating the leftovers for dinner every single night. We’re baking it again for Christmas morning and I’m showing you exactly how to make it in today’s blog post. Bonus: you can prep it the night before!

Let’s Make Biscuit Breakfast Casserole

There are 3 layers: This biscuit breakfast casserole is a total low-key breakfast where you can mix and match your favorite add-ins, just like regular breakfast casserole. Only here, we’re putting biscuits right on top! I use feta cheese, red bell pepper (or use a festive combination of 1/2 red pepper and 1/2 green pepper, like I do in my hash brown breakfast skillet), parsley, and sausage. Pre-cook the sausage or switch it up with crumbled cooked bacon. Ham would be fantastic also; just cube cooked ham like we do in ham and potato casserole. For the cheese, use your favorite. We loved feta in this dish, but shredded pepper jack, smoked gouda, or cheddar cheese would be AWESOME.

Biscuit Topping

You have options here! You can make the biscuits from scratch or use canned biscuits. I recommend homemade and the great news is that you only need a handful of easy ingredients like flour, butter, and milk. It’s the same biscuit topping we use when making this vegetable pot pie, too. Shape the biscuit dough into rounds. The biscuit balls can be super sloppy because it’s the morning and we’re all tired. See mine as the example. They look like cauliflower but MAN ARE THEY GOOD.

I reduced down my biscuits recipe for the topping. I swapped out buttermilk for whole milk because you’re using whole milk in the egg casserole. If you have it, you can use buttermilk in the biscuit dough.

Before baking, brush the biscuits with melted butter and sprinkle the entire casserole with fresh parsley, ground pepper, and extra cheese. This helps create an incredible crunchy biscuit crust.

Make Ahead Breakfast

If you’re entertaining or just need a head start on tomorrow’s breakfast, prepare and assemble the entire biscuit breakfast casserole the night before. Remove from the refrigerator as the oven pre-heats, then bake for an extra minute or two. See my instructions. Serve with a little fruit salad to complete the meal. If it’s a special day and you run out of oven space, add some slow cooker cinnamon rolls to the feast. This make-ahead casserole is one of my favorite Easter brunch recipes. You can also freeze the assembled biscuit casserole. See my instructions in the recipe! Can someone make croissant-topped breakfast casserole and report back? Yum!
