Ingredients Needed
- Breakfast Sausage: Provides delicious savory flavor that helps ties together the other ingredients.
- Red Bell Peppers: You can use any kind of bell pepper you prefer; I like the pops of red color!
- Bacon: This breakfast staple adds a signature smoky and salty flavor.
- Frozen Hash Browns: This convenient ingredient can be added to the casserole right from frozen for a super-easy shortcut.
- Shredded Cheese: I use cheddar cheese and pepper jack for this dish.
How to Make this Slow Cooker Breakfast Casserole
- Step 1: In a large skillet, cook the ground sausage over medium high heat until mostly browned.
- Step 2: Add in the peppers and onions and cook until fragrant and softened. Set aside.
- Step 3: In the same skillet, add the chopped bacon and cook for 1 to 2 minutes, or until crispy. Transfer to a paper towel lined plate to drain excess oil.
- Step 4: In a large bowl, combine eggs, milk, salt and pepper.
- Step 5: Cover the bottom of the slow cooker with a layer of frozen hash browns.
- Step 6: Layer half of the sausage and pepper mixture on top.
- Step 7: Cover with a layer of shredded cheese.
- Step 8: Repeat with the rest of the sausage mixture and the rest of the cheese, then pour the egg mixture over top. Cover and cook on low for 7-8 hours or on high for 3-4 hours. Sprinkle with bacon and green onions then serve!
Recipe Tips
- Don't worry about thawing the hash browns, they can be added to the slow cooker without any prep!
- Feel free to swap out the cheese for whatever variety you like.
- If you want your cheese extra melty, buy a block of cheese and grate it yourself instead of buying pre-shredded.
- You can use a spicy sausage if you want your casserole to have a bit of a kick to it.
- Leftovers can be stored in an airtight container in the fridge for 2 to 3 days.
- Reheat individual portions in the microwave. Check the center to make sure the casserole is heated all the way through.
Recipe FAQ's
This is likely due to undercooking, or there could be excess moisture because of ingredients like the peppers or even the onion. Be sure to cook the casserole all the way through to eliminate a thin or watery consistency.
No preheating is needed, but if you're worried about the casserole sticking there are a couple of things you can do to prevent this. Spritz the slow cooker with some cooking spray, or use a slow cooker insert like slow cooker liners to help eliminate cleanup as well!

Breakfast for dinner is the BEST! Happy you enjoyed it Brenda 🙂
Another excellent recipe! I made this for dinner last night and it was amazing! (Breakfast for dinner is the best!) The eggs were much fluffier than in an oven baked breakfast casserole! The cheese on top was so deliciously melty! I was pleasantly surprised to find out I now have another use for the crockpot! Who knew!
Here is a recipe for the oven, enjoy! https://butteryourbiscuit.com/easy-breakfast-casserole/
