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.
