The mix of cheddar and mozzarella cheeses ensures every bite of your Crockpot Breakfast Casserole is both sharp and creamy.

Cheddar and mozzarella are classic, but you can elevate your casserole with pepper jack, smoked gouda, colby jack, or fontina for a custom flavor blend.

Pair with Sweet Sides

How to Make Crockpot Breakfast Casserole Step-by-Step
Step 1: Prepare Your Crockpot
Before you layer a single ingredient, spray your 6-quart crockpot thoroughly with nonstick spray. This makes cleanup easier and ensures your Crockpot Breakfast Casserole comes out in clean, delicious scoops. You can also use a slow cooker liner for effortless cleanup my mom swears by it.
Step 2: Layer the Base
Start by spreading half of the frozen shredded hash browns evenly across the bottom. No need to thaw them just toss them in right from the bag. This forms the hearty foundation of your breakfast casserole.
Step 3: Add Cooked Sausage
Next, layer in half of your browned and drained breakfast sausage. Whether you’re using classic or maple, make sure it’s fully cooked and crumbly. You can brown the sausage the night before to save time in the morning.
Step 4: Cheese, Please
Sprinkle half the cheddar cheese and half the mozzarella cheese over the sausage layer. This step guarantees every bite of your Crockpot Breakfast Casserole is rich and melty. For extra flair, add a light layer of sliced green onions here as well.
Step 5: Repeat the Layers
Repeat the hash browns, sausage, cheeses, and green onions one more time, building the second layer of this hearty dish. It’s like lasagna, but breakfast-style!
Step 6: Mix the Egg Mixture
In a large mixing bowl, whisk together 12 large eggs, ½ cup milk, ½ teaspoon salt, and ¼ teaspoon pepper until smooth. Pour this egg mixture slowly and evenly over the top of your casserole layers. Make sure it’s well distributed so everything cooks evenly.
Step 7: Set It and Forget It
Place the lid on your crockpot and choose your cook time:
- Cook on LOW for 8–9 hours for overnight ease
- Cook on HIGH for 4 hours if you’re making it in the morning
Resist the urge to lift the lid early. Let the Crockpot Breakfast Casserole do its thing low and slow wins the flavor race.
Step 8: Check for Doneness
The top should be golden brown, and the center should be firm and fully set. If it still jiggles or feels undercooked in the center, give it another 30 minutes. A browned top doesn’t always mean the middle is done especially when cooking on HIGH.
Step 9: Serve and Enjoy
Once cooked, turn off the slow cooker and let the casserole sit for 10–15 minutes before serving. This allows it to firm up and makes scooping much easier. Serve hot, topped with green onions, salsa, or avocado slices.
Best Tips and Tricks for Crockpot Breakfast Casserole Success
Don’t Let the Top Fool You
One of the most common mistakes people make with Crockpot Breakfast Casserole is judging it by its top. Just because it looks browned and firm doesn’t mean it’s cooked all the way through. The center often needs more time, especially if you’re cooking on high heat. Always check the middle for doneness before turning off the slow cooker.
Use a Slow Cooker Liner or Spray Generously
Casseroles can stick to the sides of a crockpot, making cleanup frustrating. To avoid this, either line your crock with a slow cooker liner or spray it thoroughly with nonstick spray before layering ingredients. It ensures each scoop of your breakfast casserole lifts out easily and looks great on the plate.
Assemble Ahead for a Stress-Free Morning
Want to save time? You can prep this entire Crockpot Breakfast Casserole the night before:
- Brown the sausage and refrigerate
- Shred or portion out your cheeses
- Whisk the eggs and milk and store in a covered bowl
- Layer everything in your crockpot and refrigerate until morning
Just plug it in and cook on low for 8–9 hours overnight. You’ll wake up to the aroma of breakfast, no alarm clock needed.
Don’t Overcook the Eggs
Eggs can turn rubbery if overcooked. Stick closely to the recommended time 4 hours on HIGH or 8 hours on LOW—and check the center for doneness as soon as time’s up. Let the casserole rest 10–15 minutes after cooking so it firms up before scooping.
Make Room for Leftovers
This recipe is made for sharing, but if you’ve got leftovers, you’re in luck. Crockpot Breakfast Casserole reheats beautifully:
- Store in individual portions in airtight containers
- Reheat in the microwave for 1–2 minutes (stir halfway)
- Freeze extra portions for up to a month
Having ready-to-go breakfast in the freezer? That’s a win.
Crowd Control: Adjusting for Groups
This dish feeds 8–10 people using a 6-quart crockpot, but if you’re cooking for fewer, cut the ingredients in half and reduce the cooking time. Just keep an eye on it smaller casseroles can finish quicker.
Keep a Toppings Bar Nearby
Take your serving game up a notch. Create a mini toppings bar so your guests can customize their bowls. Favorites include:
- Chopped green onions
- Salsa or pico
- Diced avocado
- Shredded extra cheese
- Pickled jalapeños
- Hot sauce or sour cream
Whether it’s for brunch, a holiday, or just meal prep, these tips make your Crockpot Breakfast Casserole foolproof and even more enjoyable.

Store It Right for Freshness and Flavor
After everyone’s had their fill, you’ll likely still have some delicious Crockpot Breakfast Casserole left especially if you made the full 6-quart batch. Good news: it stores incredibly well and tastes just as good the next day.
- To store in the fridge: Let the casserole cool slightly, then scoop individual servings into airtight glass or BPA-free containers. Store in the refrigerator for 3–4 days.
- To store the full casserole: You can also keep the entire crock insert (if removable) in the fridge, covered with its lid or wrapped in plastic.
Just make sure the dish has cooled before sealing to prevent moisture buildup.
Reheat for Quick Weekday Breakfasts
This is where Crockpot Breakfast Casserole really shines it reheats beautifully. Busy weekday mornings? No problem.
- Microwave Method: Place one serving in a microwave-safe dish. Reheat on medium for 1 minute, stir or break it up, then continue for another 30–60 seconds until hot.
- Oven Method: Reheat in a small baking dish at 325°F for about 10–15 minutes for a slightly crisped top.
This reheating flexibility makes it a smart choice for meal prep breakfasts all week long.
Freeze for Future Meals
Want to save even more time? You can freeze Crockpot Breakfast Casserole in single-serve containers or resealable freezer bags.
- To freeze: Let the casserole cool completely. Scoop into freezer-safe containers, removing as much air as possible. Label and date each container.

Crockpot Size, Cook Times & Troubleshooting Tips
What Size Crockpot Do You Need?
The original Crockpot Breakfast Casserole recipe is designed to perfectly fill a 6-quart slow cooker. This size provides plenty of space for layering ingredients evenly and allows the eggs to set without overflowing. It also feeds 8 to 10 people comfortably perfect for family brunches or holiday gatherings.
- Cooking for fewer people? You can cut the recipe in half and use a 4-quart crockpot. Just remember to reduce the cook time slightly.
- Hosting a large group? Use two 6-quart crockpots or prep two batches back-to-back for easy serving.
Using the right size crockpot is key to achieving even cooking and the right texture throughout your casserole.
High or Low? Cook Time Options That Work for You
The beauty of a Crockpot Breakfast Casserole lies in its flexibility. You can choose a cook time that fits your schedule whether you’re planning ahead or working on a tight morning timeline.
- Low for 8–9 hours: Ideal for overnight cooking. Prep everything the night before, turn it on, and wake up to breakfast ready to serve.
- High for 4 hours: Best for same-day prep. Perfect if you start early and serve brunch later in the morning.
Important: Don’t lift the lid while cooking! Each peek releases heat and extends the cook time.
How to Know It’s Done
Because appearances can be deceiving, especially with egg-based dishes, it’s important to use these methods to check for doneness:
- Touch Test: The center should feel firm not jiggly when gently pressed.
- Knife Test: Insert a clean knife into the middle. If it comes out clean, your casserole is done.
- Visual Cue: The top should be puffed up and lightly golden, but not dry or cracked.
Common Troubleshooting Issues (And How to Fix Them)
❌ My casserole is too watery.
✔️ This can happen if you use thawed hash browns or add veggies with high water content. Next time, use frozen hash browns straight from the bag and sauté watery vegetables before adding them.
❌ The center didn’t cook through.
✔️ Make sure your crockpot is the correct size and don’t overfill. Also, always cook with the lid on and avoid opening it until the end.
❌ It’s overcooked or rubbery.
✔️ Cooking too long or on too high a setting can dry out the eggs. Use the LOW setting for longer, gentler cooking, and always check for doneness near the minimum cook time.
Pro Tip: Keep It Warm Without Overcooking
If you’re not serving the Crockpot Breakfast Casserole immediately, switch your slow cooker to “WARM” once it’s done cooking. This keeps the food at a safe serving temperature without continuing to cook the eggs.
