Gather Your Ingredients for Breakfast Casserole with Biscuits

Alright, let’s talk about what you’ll need to whip up this amazing Breakfast Casserole with Biscuits. It’s really not a huge list, which is part of why I love it so much! I always try to use good quality ingredients because, you know, it really does make a difference in the final flavor. You’ll need:

For the Casserole Base

First up, the heart of the casserole! You’ll want:

  • 1 pound of sausage, already browned and drained. My favorite is a good Italian or breakfast sausage, but you do you!
  • 1 cup of shredded cheddar cheese. Sharp cheddar gives it a nice punch.
  • 1 cup of chopped onion. A yellow or white onion works beautifully here.
  • 1 cup of chopped bell pepper. I like green for a classic flavor, but red or yellow adds a touch of sweetness.
  • 6 large eggs. Make sure they’re fresh!
  • 2 cups of milk. Whole milk makes it extra creamy.
  • 1/2 teaspoon of salt.
  • 1/4 teaspoon of black pepper.

For the Biscuit Topping

And for that irresistible crunchy, fluffy top layer:

  • 1 can of refrigerated biscuits (the 8-count size is perfect). They get so golden and yummy on top!

Step-by-Step Guide to Making Your Breakfast Casserole with Biscuits

Alright, let’s get this party started! Making this Breakfast Casserole with Biscuits is honestly a breeze, especially once you get rolling. The key is to have everything prepped so you can just layer it all up and let the oven do its magic. Don’t worry, I’ll walk you through every single part!

Preparing the Casserole Base

First things first, crank that oven up to 375ยฐF (190ยฐC) and give your 9×13 inch baking dish a good greasing. In your skillet, brown that sausage until it’s nice and crumbly. Now, this is important: drain off as much of that greasy stuff as you can. Nobody wants a greasy casserole! Stir in your shredded cheddar cheese, chopped onion, and bell pepper. Cook it for just a couple of minutes until those veggies start to soften up a bit. You want them tender, not mushy!

Creating the Egg Mixture

While your sausage mixture is hanging out, grab a separate bowl. Whisk together those 6 large eggs with the 2 cups of milk, the salt, and the pepper. Make sure you get it all mixed up really well until it’s smooth โ€“ this is what creates that lovely, custardy base for our casserole.

Assembling and Baking Your Breakfast Casserole with Biscuits

Now for the fun part โ€“ putting it all together! Spread that yummy sausage and veggie mixture evenly across the bottom of your greased baking dish. Next, pour that whisked egg mixture right over the top. Try to get it as even as possible. Now, unwrap those refrigerated biscuits and arrange them on top of the egg mixture. You can even cut them in half if you like those little bites of biscuit goodness scattered throughout. Pop the whole thing into your preheated oven. Bake it for about 40 to 45 minutes. You’ll know it’s ready when the egg mixture is completely set and those beautiful biscuits are puffed up and golden brown. Seriously, the smell will drive you crazy! Once it’s out, let this gorgeous Breakfast Casserole with Biscuits rest for about 5 to 10 minutes before you dig in. This helps everything settle nicely.

Tips for the Perfect Breakfast Casserole with Biscuits

Making a truly knock-your-socks-off Breakfast Casserole with Biscuits is all about a few little tricks I’ve picked up over the years. You want that perfect balance โ€“ fluffy biscuits, a set and creamy egg base, and no soggy bits, right? First off, don’t skip draining that sausage grease really well; it makes a huge difference in the final texture. Also, make sure your oven is fully preheated before that casserole goes in. A proper heat ensures those biscuits get gorgeously golden and puffy while the egg mixture sets up just right. If you’re worried about the biscuits sticking, a little extra spray of cooking oil on them before baking can work wonders, giving you that perfect crisp!

Ingredient Notes and Substitutions

Now, let’s chat about these ingredients for our Breakfast Casserole with Biscuits. While the recipe is fantastic as is, I totally get wanting to mix things up! For the sausage, if you’re not a fan of pork, turkey sausage works great, just make sure to get a good savory kind. And cheese? Oh, you can totally swap the cheddar for Monterey Jack, a Colby blend, or even some pepper Jack if you like a little kick! As for veggies, mushrooms are amazing in here, or a bit of finely chopped spinach wilted down works too. The eggs and milk are pretty essential for that custardy base, but you *could* try a dairy-free milk if needed, though it might affect the creaminess a smidge.

Serving Suggestions for Your Comforting Breakfast Casserole

This hearty Breakfast Casserole with Biscuits is practically a meal in itself, but if you want to round things out for a truly spectacular brunch, consider some fresh fruit! A simple side of sliced melon or berries feels so light and refreshing against the rich casserole. And of course, a steaming cup of coffee or a tall glass of orange juice is pretty much mandatory, right?

The Magic of Making Ahead (and Keeping it Delicious!)

So, youโ€™ve made this absolutely incredible Breakfast Casserole with Biscuits and, *gasp*, there are leftovers! Don’t you worry, it stores like a dream. Just let it cool down a bit, then pop it into an airtight container or cover your baking dish tightly with plastic wrap and then foil. It’ll stay yummy in the fridge for about 3 to 4 days. Perfect for having breakfast ready to go during the week!

Reheating is super simple too. For individual portions, a quick zap in the microwave usually does the trick. But if you want to warm up a bigger piece or get those biscuits nice and crispy again, I highly recommend popping it back into a moderate oven โ€“ maybe around 350ยฐF (175ยฐC) โ€“ for about 15-20 minutes, or until it’s heated all the way through. You can even pop a lid on it for the first 10 minutes to ensure the inside gets warm without the biscuits getting too hard.
