This Sausage Hashbrown Breakfast Casserole is an easy crowd-pleaser! You can prep and store it overnight before cooking it in the morning.
This is one of my favourite things to make for Christmas morning. My family alternates between this and my French toast casserole because it's so easy to assemble for a big group and EVERYONE loves it!
Why You'll Love This Recipe
- Make it ahead: Assemble it up to 3 days ahead of time, then cook in the oven.

Ingredients and substitutions
- Turkey sausage – make it with bacon, ham or chicken instead.
- Butter – or a butter substitute of your choice.
- Eggs – fresh eggs are best but eggs from a carton will work in a pinch.
- Frozen hashbrowns – frozen tater tots would be good.
- Red and green pepper – try spinach, broccoli, diced tomatoes or mushrooms instead.
- Red onion – white or yellow onion can be used, but will have a milder flavour.
- Cheese – cheddar, Swiss and Tex Mex cheese are all great options.

Recipe tips & tricks
Here are some of my top tips for making the best casserole:
- Use another protein: Italian sausage, bacon, ham or leftover chicken are great options.
- Try egg whites: Swap out half the eggs for egg whites (about 1 cup liquid egg whites).
- Serve with sides: Serve with toast, fruit salad or your favourite caffeinated beverage.

If your casserole is soggy, you may have gone overboard on the toppings. You should only have about 3-4 cups of toppings.
Do you need to thaw the hashbrowns first?
You only need to thaw the hashbrowns if you're assembling the casserole a few days before cooking it.
