Sweet Potato Breakfast Casserole
This Sweet Potato Breakfast Casserole is a great meal prep recipe. Easy to reheat for breakfast and lunch throughout the week!
Sometimes it’s hard to believe the recipes I HAVEN’T shared around here. These often include things that my family eats on at least a bi-weekly basis! One of those things is a classic breakfast casserole.
I did share a leftover cornbread breakfast casserole a few years back, but that’s more of a special occasion recipe for us, I guess (it’s in the same category with waffles and ice cream and lemon pancakes).
The one I’m talking about today is something we make at least every other week, and also serve every time I host a brunch buffet.
It involves cleaning out the fridge of whatever vegetables and cheese we have, pouring eggs over it, and baking. The ingredients may differ, but the technique is always the same.
We do this on a Sunday, and then eat the casserole throughout the week for breakfast and lunch, when we’re not eating savory cottage cheese breakfast bowls or egg salad with pickles.
Adults and the toddler alike both love this casserole. Here’s what I made yesterday, for us to eat this week.
Is a sweet potato good for breakfast?
This week, I happened to have one sweet potato in my pantry, so I thought “hmmm . . . can this go in breakfast casserole?” The answer, of course, is why not?
Sweet potatoes are a great source of fiber, complex carbohydrates and Vitamin A, making them a perfect food to fuel your day with. Add in the protein from the eggs, sausage and cheese, and this is a breakfast that will keep you going.
Why this casserole is one of the best sweet potato breakfast recipes:
No need for a side dish for this recipe! You’ve got your eggs, breakfast meat (feel free to substitute oven baked bacon, turkey bacon in the oven or turkey bacon in an air fryer for the sausage here, like in my breakfast muffins), and a side of (sweet) potatoes, all in this one side dish. It’s great for meal prepping because it reheats so well.
I love this casserole because once you’ve learned the basic techniques, you can change it up in any number of ways. You’ll find yourself raiding your fridge and pantry every weekend for a new casserole!
Use any cheese you happen to have in the fridge for this. If you’re a fellow goat cheese lover like me, be sure to bookmark my cranberry appetizer for Thanksgiving!
It’s important to start by roasting any vegetables or meats that require a longer cooking time. If you’re using fresh greens like spinach or kale, you’ll want to chop them up so that they cook down easier.
And I like to add a little milk to my eggs to make the eggs stretch further.
How do I reheat this?
Honestly, I go for fast and lazy and just pop a piece into the microwave for about a minute. You can always reheat it in a toaster oven or regular oven. Make sure the inside reaches 165 degrees F for food safety.
What to serve with sweet potato breakfast casserole:
Like I said, definitely no side dish needed here! But why not treat yourself to a fancy coffeehouse drink like a caramel coffee, mocha hot chocolate or tea latte?

Maybe my oven isn’t working properly, but my little breakfast sausages needed a LOT more than 10 mins to cook (although maybe they were only supposed to be heated up?), so I just browned those up on the stove and gave the sweet potato a bit longer in the oven as well while I made your lemon pancakes :). Both were absolutely delicious, and will be making again!
I’m so glad you liked this casserole and the lemon pancakes, Molly! I used Johnsonville brand breakfast sausage, and the package directions are are 350 degree F oven for 12 to 15 minutes. I cut a few minutes off of that because the sausage will be sliced and cooked another 35 minutes in the casserole itself. Hope that makes sense!
What a great idea! I love the idea of cleaning out the excess veggies in the fridge, because my husband chronically over-buys veggies. This last week I went to use some of the grape tomatoes he bought a ton of, and they were all significantly shriveled (thank you dry desert air) plus starting to rot. But if I’d picked through them they would probably have worked in this. My brain is going into overdrive thinking of ways to vary the recipe…
Haha yes! We don’t necessarily over-buy veggies (although maybe we do?), but we just always have odds and ends of them left over. Grape tomatoes are OFTEN in these egg bakes for us. I usually blister them under the broiler, or in a skillet, first, to release some of their water.
