This Crockpot Breakfast Casserole is a delicious make-ahead breakfast with hashbrowns, bacon, veggies and eggs. It’s great for the holidays!
Ingredients and substitutions
- Cooking spray – you’ll need this to grease the crockpot. You could also grease it with butter.
- Frozen hashbrowns – frozen tater tots or frozen potatoes would also be good.
- Bacon – use pork bacon or turkey bacon for a healthier option. You could also swap out the bacon for sliced-up breakfast sausage or ham.
- Bell pepper – swap out for another veggie of your choice like spinach.
- Red onion – use white onion, shallots or another veggie of your choice.
- Eggs – you could try using eggs from a carton but fresh eggs are best.
- Salt & pepper – to taste.
- Cheddar cheese – leave off the cheese or swap it out for another type of cheese like Swiss or Monterey Jack.

Frequently Asked Questions
Part of what I love about this slow cooker breakfast casserole is that you can make it a few days in advance. If you're celebrating something special and want to have everything cooked before guests arrive, you can have this breakfast casserole going a few days before. It will last in the fridge for up to 5 days, so it's perfect for your weekly meal prep! You can also assemble the casserole the night before cooking it – you just need to keep the crockpot in the fridge so the ingredients don't go bad.
For safety reasons, I wouldn't recommend leaving the casserole to cook in the crockpot overnight. You can add all the ingredients to the crockpot and store it in the fridge overnight, then set it to cook in the morning.
This breakfast casserole is an entire dish on its own, but if you want, you can serve it with some fresh fruit, a smoothie or your favourite caffeinated beverage.
There's no need to cook the eggs before adding them to the crockpot. They'll cook alongside the other ingredients.
If you find that your breakfast casserole is dry, you've likely cooked it for too long. Make sure you're only cooking it on high for 4 hours – any longer, and it will start to dry out.
Storing and reheating
You can store this breakfast casserole in the fridge for up to 5 days. I recommend storing individual portion sizes in glass meal prep containers so that all you have to do is take one out of the fridge and reheat it for 2 to 3 minutes. Sprinkle a little bit of water over top before reheating to ensure it doesn't dry out, and the leftovers will taste just like new!
Can you freeze breakfast casserole?
Yes! This breakfast casserole is definitely freezable after it’s been cooked. Store individual portions in glass containers with lids and freeze for up to 3 months. You can reheat it in the microwave straight from frozen. Sprinkle a bit of water over top then reheat for 6 to 7 minutes, checking on it halfway through the cooking time.

How much in a serving?
Taylor Stinson says
I don’t provide servings by weight/cup unfortunately. You will need to take the number of servings listed and divide into portions. Each portion is a serving.
Mike says
This dish was delicious and did not last long in our family! We will be making it again for Christmas morning!
Taylor Stinson says
I’m so happy you all enjoyed 🙂
Jeff says
Do you think you could put the slow cooker on low and cook overnight? It’d be great to wake up to a hot breakfast!
Taylor Stinson says
I wouldn’t advise leaving your crockpot on unattended for safety reasons but you may want to refer to your user manual to check and see what is safe!
Kelly says
I wonder the same that would be nice
Aly says
Has anyone tried this with cauliflower hashbrowns before?
Taylor Stinson says
I have not and I’m not sure how well they would work. I imagine they would give off a lot of excess liquid but you could always try them out!
