Ingredient Notes and Substitutions
- Avocado oil or cooking spray: to prevent the canned sweet potato casserole from sticking to the baking dish.
- Canned cut yams: you can substitute the yams for canned sweet potatoes. This eliminates the cooking and peeling. If you’d like to use fresh sweet potatoes, we have directions for making them in our sliced sweet potatoes recipe.
- Heavy cream: although I recommend heavy cream, you can substitute half and half if you need to.
- Eggs: are necessary to bind the ingredients together, don’t skip this important ingredient.
- Spices and herbs: these seasonings add the ideal mix of flavors.
- Panko and seasoned breadcrumbs: I’ve found that this duo are perfect for this recipe. The Panko is light and airy while the traditional breadcrumbs provide a crispy texture.
- Parmesan cheese: this cheese is my first choice for this dish, but shredded Pecorino Romano or Grana Padano are a great alternative.
As you’ll see we don’t use any marshmallows or brown sugar. So this sweet potato casserole no marshmallows recipe is ideal when you’re looking for a healthier alternative to the traditional marshmallow covered version.

Recipe Variations

Serving Suggestions
This savory sweet potato casserole is a favorite throughout the fall and winter months, making it a staple for holiday meals and even Easter dinner. It pairs beautifully with Dr. Pepper ham, Crockpot turkey tenderloin , or our baked Italian chicken cutlets, creating a well-balanced and flavorful spread. Serve it straight from a casserole dish for a rustic and comforting presentation.
For those who enjoy a bit of warmth in their dishes, adding a dash of cinnamon or pumpkin pie spice to the filling can enhance the natural sweetness of the sweet potatoes without overpowering the savory elements. If you’re looking for a little contrast, a touch of pineapple can brighten up the flavors, making this casserole even more dynamic.
To elevate the dish further, garnish with fresh herbs like rosemary for an earthy and aromatic finish.

I’m not a fan of overly sweet casseroles so when I found this I was excited. This was a hit at dinner and we will be making it again.

Iโn giving this a 4/5 only because I havenโt made it yet. I can pretty much read a recipe and know if it will be something Iโd want to eat again. The only reason I havenโt made this yet is because my refrigerator is out and I have a very small extra one that is too full! Now I do have a question or comment based on reading this: How do you get 10 sevings from an 8×8 pan? Iโm seriousโฆ.that would feed two of us a couple of times. But we like sweet potatoes.
