Here’s what you’ll want to gather:

That’s really it! See? Simple. Just toss these on your shopping list and you’re halfway to breakfast heaven.
How to Prepare Your Crockpot Breakfast Casserole (Slow Cooker)
Alright, getting this Crockpot Breakfast Casserole ready to go is ridiculously easy. I swear, it takes less time than trying to decide what to wear on a Monday morning! Just follow these simple steps, and you’ll have a delicious breakfast ready to roll.
Step 1: Brown the Sausage and Sauté Vegetables
First things first, grab a skillet and set it over medium heat. Toss in your breakfast sausage, casings removed, and get to work breaking it up with your spoon until it’s all nicely browned. This is super important because it gets rid of that excess grease, which nobody wants hanging around in their breakfast! Once the sausage is cooked, toss in your diced onion and bell pepper. Let them soften up for about 5-7 minutes, just until they’re tender and smell amazing.
Step 2: Prepare the Slow Cooker and Add Sausage Mixture
Now, grab your slow cooker insert. A quick spray of cooking spray or a little wipe of butter keeps things from sticking – nobody likes scraping! Spread that yummy sausage and veggie mix evenly all over the bottom of your slow cooker. This is going to be the hearty base of our casserole.
Step 3: Mix the Egg Base
In a separate bowl, let’s get our egg mixture ready. Whisk together those 6 large eggs, the milk, salt, and pepper like you mean it! You want it all to be really well combined so you don’t get any surprise pockets of plain egg later. It should look nice and smooth.
Step 4: Assemble the Crockpot Breakfast Casserole (Slow Cooker)
Carefully pour that beautiful egg mixture right over the sausage and veggies in the slow cooker. Try to get it as evenly distributed as possible. Then, the grand finale – sprinkle that shredded cheddar cheese all over the top! It’s going to melt into gooey, cheesy goodness.
Step 5: Cook and Rest
Pop the lid on your slow cooker. You’ve got two options here: cook it on LOW for about 4 hours, or if you’re in a bit of a hurry, you can go for HIGH for around 2 hours. You’ll know it’s done when the eggs are completely set and the cheese is all melty and bubbly. Once it’s ready, here’s a pro-tip: let it sit for about 5-10 minutes before you dig in. This helps everything firm up and makes it easier to serve. Trust me, it’s worth the tiny wait! If you’re looking for more make-ahead breakfast ideas, check out my breakfast burritos.
Tips for the Best Crockpot Breakfast Casserole (Slow Cooker)
You know, I’ve made this Crockpot Breakfast Casserole so many times, I’ve picked up a few little tricks that make it even better. Don’t overcook those eggs! They can go from perfectly set to a little rubbery in the slow cooker really fast, so keep an eye on it towards the end. Also, if you’re worried about it being a bit watery – and this happens especially if your veggies release a lot of moisture – just tilt the slow cooker slightly and carefully spoon out any excess liquid before you serve. It makes a huge difference! For more easy breakfast wins, check out my tips for quick breakfasts!
Ingredient Notes and Substitutions
Okay, let’s chat about some of the ingredients in this Crockpot Breakfast Casserole and how you can tweak them to fit your life! Sometimes you’re out shopping and can’t find exactly what the recipe calls for, or maybe you just want to mix things up. Totally get it!
The breakfast sausage is usually pretty forgiving. If you can’t find bulk sausage, you can just slice up a few links and brown them up. Just make sure to remove any casings first! For the cheese, cheddar is awesome, but feel free to go wild. Monterey Jack, a spicy pepper jack, or even a Colby blend would be fantastic. If you’re dairy-free, there are some really good cheddar-style shreds out there now that melt surprisingly well. And for the milk? Any kind works in a pinch, but if you’re going plant-based, a simple unsweetened almond or oat milk will do the trick just fine without changing the flavor too much.
Make-Ahead and Storage Instructions
This Crockpot Breakfast Casserole (Slow Cooker) is practically *designed* for make-ahead magic! For those super busy mornings, you can totally prep everything the night before. Just cook the sausage and veggies, whisk the eggs, and assemble it all in the slow cooker insert. Cover it, pop the insert into the fridge, and in the morning, just put it in the base and set it to cook. Easy peasy! Leftovers? Oh yeah, they’re great. Just toss any extra casserole into an airtight container and it’ll last about 3-4 days in the fridge. To reheat, I usually zap a slice in the microwave for about 30-60 seconds, or you can gently warm it in a low oven if you have a bit more time.

Frequently Asked Questions about Crockpot Breakfast Casserole
Got a question about our favorite Crockpot Breakfast Casserole (Slow Cooker)? I’ve probably answered it a million times in my head while making it! Here are a few things people often ask:
Can I add more veggies to this breakfast casserole?
Absolutely! This recipe is super flexible. Feel free to toss in some mushrooms, spinach, diced zucchini, or even some leftover roasted sweet potatoes. Just make sure to sauté any raw veggies like mushrooms with the onions and peppers so they soften up nicely. You might need to add a few extra minutes to the cooking time if you add a lot of extra moisture-rich veggies.
Why is my breakfast casserole watery?
Sometimes the veggies can release a bit too much liquid, or if you didn’t drain the sausage well, that can contribute. The best trick is to carefully spoon out any excess liquid once it’s almost done cooking. Also, making sure your eggs are really whisked well and that you didn’t add too much milk can help prevent a watery bottom. It’s all about striking that perfect balance!
Can I freeze this slow cooker breakfast casserole?
You sure can! Once it’s completely cooled, slice it up and freeze individual portions in airtight containers or freezer bags. They should be good for about 1-2 months. To reheat, you can pop a slice in the microwave or a low oven until it’s warmed through. They’re almost as good as fresh!
What if I don’t have breakfast sausage?
No worries! You can use other cooked meats. Crumbled bacon, diced ham, or even some browned ground beef would work wonderfully. Just make sure whatever meat you use is fully cooked before adding it to the slow cooker. For a vegetarian option, you could skip the meat and load up on extra veggies and maybe some black beans!
