Sweet Potato Casserole

Is it a dessert or is it a side dish? I think we like to label it as a side dish so we still can have a second dessert later.

This is my new favorite sweet potato casserole! It’s not overly sweet, so it still works as a Thanksgiving side dish, and I’m addicted to that crisp, cinnamon crumble pecan topping.

Sure, those marshmallow toppings are good but this pecan topping variation is even better! I just love every last thing about it. Trust me, it’s going to disappear in no time!

What is the Difference Between Yam and Sweet Potato?

It can be so confusing. I sometimes get comments on my sweet potato recipes with people claiming I’m labeling them all wrong. So just wanted to clear things up.

  • Sweet potatoes generally have tapered ends, thin, smooth skin and flesh that can range from light yellow to dark orange (and even to purplish). They are wetter.
  • Yams have a cylindrical shape with brown, rough, bark-like skin and usually has a white or purple flesh. They are starchier and dry.

Usually here in the U.S. I think you’ll now most commonly find them labeled as “sweet potatoes” but you still might find a “yam” labeling here and there. Just look for the ones like so…

Can I Make This in Advance?

Both the sweet potato portion and topping can be made a day in advance then chilled separately in the fridge. Let rest at room temperature 30 minutes, add the topping and bake.

A Classic Thanksgiving Side Dish

Sweet potato casserole is a staple holiday recipe at my house. Thanksgiving dinner just wouldn’t be the same without it. Along with turkey, mashed potatoes and gravy, dinner rolls, mac and cheese, veggie side dishes, pies, pies, and more pies. I can’t wait!

I hope this sweet potato casserole becomes a new yearly tradition in your home! It’s definitely one of the best uses for sweet potatoes.

    Looks really good but can I make this for a homeless dinner using canned sweet potatoes that are already mashed? Like canned pumpkin?

    • Jaclyn

      Jaclyn Bell

      Canned mashed sweet potatoes should substitute just fine here. That’s very nice of you by the way! Happy Holidays!

  • Judy

    Well… I made this for thanksgiving and I was concerned because I didn’t have unsalted butter so I used salted butter,I didn’t have pecans so I used walnuts and after mixing the potatoe mixture together, it seemed very thin or runny. Turned out to be the hit of the meal! Not a single spoonful left! A keeper for sure! Thanks!

  • Sandy

    This was a great hit at our Thanksgiving dinner – I have received several requests to make it again next year!

  • Alysann Collotzi

    If you are gluten free, what kind of flour would be a good substitute for wheat flour?

    • Jaclyn

      Jaclyn Bell

      A gluten free flour blend like King Arthur should work well here. Then add a little more butter if needed if it seems sandy. Hope you enjoy!

    • Jaclyn

      Jaclyn Bell

      Yes you can make the filling and topping then keep separate in the fridge, let rest at room temp while the oven preheats then add the topping and bake (adding a little more time as needed since it started out cooler). Happy holidays!

  • Erika

    Can you top these with marshmallows in alternating rows like in your Brown Butter Sweet Potato Casserole? Thanks!

    • Jaclyn

      Jaclyn Bell

      That would be fine, you’ll want to wait to add the marshmallows and you won’t need quite as much of the crumble topping.

  • Dan

    Looks great! I cut the sweet potato in 1/2 longways, lightly brush with olive oil and they completely cook in 30 minutes. Then just peel off the skin. (bake at 425)

  • Amy

    But your browned butter sweet potato casserole is my favorite ever – now which one do I make for Thanksgiving?!? :)

    • Jaclyn

      Jaclyn Bell

      I know it was my favorite forever too but I think I might like this one even better. Can’t go wrong with either choice though!

      • Sherri

        Absolutely love this recipe. Is there a way to cook the topping separately so I can move it to a crock pot on warm for transport?

        • Jaclyn

          Jaclyn Bell

          Hi Sheri – I believe that would work on a baking sheet with parchment paper, then just let cool, crumble it up and store to add later.
