Savory Sweet Potato Casserole FTW
Move over marshmallows, this savory sweet potato casserole is vying for a place at the table and between you and me, I think it’s going to take first place!
Sweet potatoes are naturally sweet on their own and I’ve always found the traditional sweet potato casserole a little too sweet for me. It felt like you were eating dessert alongside your meal, which I suppose is fine, but I’m a savory casserole girl through and through.
What I love about this savory sweet potato casserole is that it is combined with both sweet potatoes and regular potatoes to balance out the sweetness even more. Don’t skip on the crispy sage butter topping — it elevates the dish and brings a contrasting texture to the smooth sweet potato and potato filling. If you’re looking for a savory spin on the classic sweet potato casserole, give this savory sweet potato casserole a try! It’s a modern twist on a classic and sometimes that’s just what we need!
Make-Ahead Tips
This savory sweet potato casserole is a great candidate for prepping and/or making ahead of time.
Peel and dice your sweet potato and regular potatoes the day before and keep them covered with cold water in the refrigerator. When you’re ready to boil them, drain and add to a large pot with fresh water.
Alternatively, if you choose, you can prep the filling ahead of time. Just don’t make the topping and top the casserole with the breadcrumbs until right before baking otherwise the topping will end up being soggy.

Variations and Substitutions
- If you prefer to use all sweet potatoes, just replace the regular potatoes for sweet potatoes.
- If you don’t like sage, you can replace with rosemary or another earthy herb to your liking.
- Heavy cream or half and half can be used instead of milk to create a richer casserole
- A great way to add flavor to this casserole is to use spices! You can sprinkle some cinnamon into the filling and mix it together or for a more savory, smokey vibe, add some smoked paprika or cayenne pepper to kick up the heat.
Storage and Reheating Instructions
Allow leftovers to cool then place into an airtight container in the refrigerator for up to 4 days. To reheat, portion into a microwave-safe bowl or container and heat until warmed through. Keep in mind the topping won’t be crunchy anymore, but you can easily make more if you’d like!
