This Crockpot Breakfast Casserole is a hearty way to start the day! With eggs, cheese, and tasty toppings like sausage or veggies, it’s a wonderful morning treat.
I love how I can toss everything in the crockpot, set it, and forget it. Perfect for lazy mornings or when I have guests over! Who doesn’t love an easy breakfast? 😄
Key Ingredients & Substitutions
Breakfast Sausage: Crumbled sausage adds amazing flavor. If you’re looking for a lighter option, try turkey sausage or even a plant-based sausage. Ground beef or ham can also work well.
Eggs: Six large eggs create a fluffy texture. For a lower-cholesterol option, consider using egg whites or egg substitutes — just use about 1/3 cup of egg substitute for each egg.
Frozen Hash Browns: Thawed hash browns are a time-saver and provide a nice base. You can substitute with diced fresh potatoes, but they will need to be par-cooked before adding to the slow cooker.
Cheddar Cheese: Shredded cheddar is classic, but feel free to experiment! Monterey Jack or pepper jack offers a nice twist. If you’re dairy-free, try a plant-based cheese.
Bell Peppers: They add color and crunch. If you don’t have bell peppers, any other veggies, like spinach or mushrooms, can add flavor. Just make sure to chop them small!
How Do You Make Sure the Eggs Are Cooked Perfectly?
Cooking eggs in a slow cooker can be tricky if you’re not careful! Follow these tips for the best results:
- Mix the eggs well with the milk and seasoning to make sure they are fully incorporated.
- Spread the ingredients evenly in the crockpot; this helps them cook uniformly.
- Check the casserole towards the end of the cooking time. If the edges are getting too brown, it may be done. A clean knife inserted comes out clean when it’s fully cooked.
- Let the casserole cool slightly before serving; this helps it set and makes it easier to scoop.
This way, you’ll avoid that sometimes rubbery texture and get beautifully fluffy eggs every time!

How to Make a Delicious Crockpot Breakfast Casserole
Ingredients You’ll Need:
Main Ingredients:
- 1 lb breakfast sausage, cooked and crumbled
- 6 large eggs
- 1 cup milk (whole or 2%)
- 3 cups frozen hash brown potatoes (thawed)
- 1 cup shredded cheddar cheese, divided
Vegetables and Seasoning:
- 1/2 cup diced onion
- 1/2 cup diced bell pepper (optional)
- 1 tsp garlic powder
- 1/2 tsp salt
- 1/4 tsp black pepper
For Garnishing:
- 2 green onions, sliced (for garnish)
How Much Time Will You Need?
This casserole takes about 15 minutes of prep time, plus cooking time in the crockpot. If you cook it on low, it will take about 6 to 8 hours, and if you choose high, it will take about 3 to 4 hours. Altogether, it’s a great set-and-forget breakfast option!
Step-by-Step Instructions:
1. Prepare Your Crockpot:
Start by lightly greasing the inside of a 6-quart slow cooker with cooking spray. This will help prevent sticking and make clean-up easier!
2. Mix the Egg Base:
In a large bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper until everything is well combined. This will create a fluffy egg mixture that will soak into all the ingredients.
3. Layer the Hash Browns:
Next, spread the thawed hash browns evenly across the bottom of the crockpot. This will act as the foundation of your casserole.
4. Add the Meat and Veggies:
Sprinkle the crumbled, cooked sausage over the hash browns. Then, add the diced onion and bell pepper on top of the sausage. This gives added flavor and color to your dish!
5. Pour the Egg Mixture:
Carefully pour your mixed egg mixture over the layered ingredients in the slow cooker. Make sure it covers everything evenly.
6. Cheese It Up:
Sprinkle 1/2 cup of the shredded cheddar cheese evenly on top of all the ingredients. Cheese makes everything better!
7. Cooking Time:
Cover the slow cooker with the lid and cook on low for 6 to 8 hours, or on high for 3 to 4 hours. You’ll know it’s done when the eggs are fully cooked and the casserole is set.
8. Add More Cheese:
During the last 15 minutes of cooking, sprinkle the remaining cheddar cheese on top and cover again to let it melt. Yum!
9. Garnish Before Serving:
Once cooked, garnish your casserole with sliced green onions for a fresh touch. This adds a nice crunch as well!
10. Serve and Enjoy:
Serve the casserole hot, scooping out portions with a spatula. Enjoy this hearty breakfast treat with family and friends!
This Crockpot Breakfast Casserole is cheesy, filling, and perfect for any morning gathering. Enjoy every bite!
Can I Use Different Types of Meat?
Absolutely! You can swap the breakfast sausage for cooked bacon, ham, or even turkey sausage for a lighter option. Just ensure it’s cooked and crumbled before adding it to the casserole.
Can I Make This Recipe with Fresh Potatoes?
Yes, you can use fresh potatoes instead of frozen hash browns! Just peel and dice them and then par-cook the diced potatoes in boiling water for about 5 minutes before layering them in the slow cooker. This ensures they cook through in the casserole.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave or in the oven until warmed through. You can also freeze individual portions for up to a month—just thaw and reheat when ready to enjoy!
Can I Add More Vegetables?
Definitely! Feel free to add additional veggies like spinach, zucchini, or mushrooms. Just make sure to chop them finely to ensure they cook evenly in the slow cooker.
