  • 1 package Refrigerated biscuit dough: I usually grab the big flaky kind, like Grands, but honestly, any refrigerated biscuit dough will work. Just make sure itโ€™s enough to cover the bottom of your pan.
  • 1 pound Breakfast sausage: Cooked and crumbled, that is! You can use mild, hot, or even a maple-flavored sausage โ€“ whatever tickles your fancy.
  • 6 Large eggs: Yep, a good handful of eggs to bind everything together and make it nice and fluffy.
  • 1 cup Milk: Whole milk gives the best richness, but 2% works too. It just adds to that creamy texture.
  • 2 cups Shredded cheddar cheese: Because whatโ€™s a breakfast casserole without a good amount of melty cheese? Sharp or mild, itโ€™s up to you!

Prepping Your 5-Ingredient Breakfast Casserole

First things first, get that oven fired up! You want to preheat it to 350ยฐF (175ยฐC). While the ovenโ€™s getting hot, grab your 9×13 inch baking dish and give it a good grease. This is crucial to make sure nothing sticks and you can get those perfect slices out later โ€“ nobody likes a stuck casserole!

Assembling the Quick Breakfast Casserole

Now for the fun part: building the layers! Start by tearing your refrigerated biscuit dough into small, bite-sized pieces. Spread these evenly across the bottom of your greased baking dish. Think of it as the fluffy, doughy foundation. Next, sprinkle all that delicious, pre-cooked breakfast sausage right over the biscuit layer. Make sure itโ€™s pretty evenly distributed so every bite gets some savory goodness.

Baking and Finishing Your 5-Ingredient Breakfast Casserole

Grab a separate bowl and whisk up those 6 large eggs with your milk. Once theyโ€™re nicely combined, pour this eggy mixture evenly over the sausage and biscuits in your baking dish. Don’t skip this step โ€“ itโ€™s what holds everything together! Finally, generously sprinkle the 2 cups of shredded cheddar cheese all over the top. Pop that dish into your preheated oven and bake for about 30 to 35 minutes. You’re looking for a beautiful golden brown color and a center thatโ€™s set, no longer jiggly. Let it sit for a few minutes before slicing into it; itโ€™s usually super hot right out of the oven!

First off, don’t skimp on the cheese! Two cups might sound like a lot, but it’s what gives you that amazing cheesy pull. Also, make sure your sausage is fully cooked and crumbled before adding it. Nobody wants a raw bite in their breakfast! And for the biscuits, tearing them into pieces rather than just plopping whole ones in helps create a more even texture throughout the casserole, so you don’t get big doughy pockets.

Ingredient Notes and Substitutions for Your Quick Breakfast

While this 5-ingredient breakfast casserole is fantastic just as it is, I love that you can totally tweak it to your liking! The beauty of keeping it simple means itโ€™s super forgiving. If you can’t find your usual brand of refrigerated biscuit dough, don’t sweat it! Any brand should work, or you could even try cut-up pieces of crescent roll dough in a pinch. For the sausage, feel free to swap it out for diced ham or even some crumbled bacon if thatโ€™s what you have on hand. And cheese? Go wild! Monterey Jack, a Colby blend, or even pepper jack would be delicious. Itโ€™s all about what makes your breakfast perfect!

Serving Suggestions for Your 5-Ingredient Breakfast Casserole

This 5-ingredient breakfast casserole is hearty enough to be a meal on its own, but itโ€™s also fantastic with a few simple sides! Think about adding some fresh fruit, maybe some sliced cantaloupe or berries, to lighten things up. A fresh green salad with a light vinaigrette is also a wonderful contrast to the rich, cheesy casserole โ€“ check out some salad ideas here! Or, for something a bit lighter, try some beautiful fresh veggie platters. It makes the whole meal feel a bit more special, even when it’s super easy!

Storage and Reheating Your Quick Breakfast Casserole

Got leftovers? Lucky you! This 5-Ingredient Breakfast Casserole (Quick) is almost as good the next day. Once it’s cooled down a bit, just pop any extra into an airtight container and keep it in the fridge for up to 3 days. If you want to stash some for later, you can totally freeze portions! Wrap individual slices tightly in plastic wrap, then tuck them into a freezer bag. They should last about a month.

When you’re ready to reheat, just pop a slice (or more!) onto a microwave-safe plate and heat for about 30-60 seconds until warmed through. If you’re reheating a larger piece, an oven at 300ยฐF (150ยฐC) for about 15-20 minutes works wonders to get it nice and hot without drying it out.
