Key Recipe Ingredients

For Pecan Streusel Topping:

  • Brown Sugar: be sure to pack it down when measuring.
  • Pecans: use toasted chopped pecans – the toasting makes a difference.
  • Butter: cold, sliced butter helps bind the topping together.
  • Cinnamon: gives this topping a fragrant fall aroma.

    * Tip: this streusel is so good, you may want to double it for a thicker layer of crunchy sweetness on top. You can also use it on this baked French toast casserole.

For the Filling:

  • Sweet Potatoes: be sure to buy the vibrant orange-fleshed sweet potatoes.
  • Eggs: these provide binding power and fluffy texture.
  • Maple Syrup: gives this dish a wonderful sweetness.
  • Vanilla Extract: provides aromatic flavor in this dish.
  • Lemon Juice: lends a bit of acidity to balance out the sweetness.

Substitutions and Variations

  • Brown Sugar: You can use either light brown or dark brown sugar; note that dark brown sugar results in a darker brown coloring but will not affect flavor.
  • Nuts: If you prefer, use toasted walnuts instead of pecans.
  • Sweet Potatoes: We highly recommend using orange-fleshed sweet potatoes, but have also made this recipe with white-fleshed sweet potatoes with success. White-fleshed sweet potatoes tend to be naturally sweeter.
  • Marshmallows: We created this recipe to be crispy and crunchy with pecans and brown sugar, but if you like, you can scatter mini marshmallows over the top instead or combine the two toppings together.

Step-By-Step Recipe Instructions

  1. Mix together brown sugar, chopped pecans, and cold butter in a small bowl until mixture is grainy and comes together. Cover and chill until ready to use.
  2. Wrap each sweet potato in foil and roast at 400F for about 1 hour, or until potatoes are very soft. Remove sweet potato skins, and mash potatoes well in a large bowl.
  1. In a bowl, beat eggs, maple syrup, vanilla, lemon juice, and salt. Mix in the mashed sweet potatoes until smooth. Transfer mixture to a buttered 9×13 dish.
  2. Sprinkle pecan topping evenly over casserole. Bake at 350F until casserole is set and topping bubbles.

Sweet potato casserole can be completely prepared in advance and baked later.

How to Prepare Ahead

  • Roast: Roast your sweet potatoes ahead of time, as that gives potatoes time to cool enough to handle. Having them roasted early also frees up your oven for that brined turkey or honey ham. It’s easy to roast a big batch of sweet potatoes and use the extras for a lovely sweet potato hummus.
  • Streusel: Rhe nutty-crunchy pecan brown sugar streusel can be fully mixed together up to several days ahead of time – cover and chill until ready to sprinkle onto casserole.
  • The Night Before: The best low-stress tip is to totally be prepare this awesome sweet potato casserole the night before. On the day of the Big Meal, you can even bake it an hour or two ahead of dinner time and keep warm until ready to serve.
  • Leftovers: Leftovers are delicious the next day; we recommend heating it up in the oven uncovered so the topping can crisp up again. Or, if you’ve still got baking gusto left in you, try this sweet potato bread that specifically makes use of leftover sweet potato casserole so nothing goes to waste.

Commonly Asked Questions

Are yams the same thing as sweet potatoes?

Yams and sweet potatoes are not the same. Most of the time, when you see produce labeled as yams, they are actually sweet potatoes. True yams originate from regions of Asia and Africa.

What kind of sweet potatoes should I use?

You may notice a few types of sweet potatoes, in varying shapes and colors, at your local grocery store or farmer’s market. Choose the bright-orange fleshed variety. You can read more about sweet potato varieties here.

Are eggs used in sweet potato casserole?

Yes, eggs are an important binding agent in most sweet potato casseroles. It also gives lift to the casserole.

Should you boil or bake sweet potatoes for use in sweet potato casseroles?

You can boil or bake your sweet potatoes prior to adding in a casserole, as long as the sweet potatoes are cooked until very soft and stringy skin has been removed. That said, we are partial to roasting/baking sweet potatoes, as this imparts such depth of flavor.

Can I make sweet potato casserole ahead of time?

You can assemble the entire casserole, minus the topping, a day ahead. Wrap tightly in cling wrap and chill until you’re ready to sprinkle on the topping and bake.

For Pecan Streusel Topping:


  • Do Ahead: Mix together brown sugar, chopped pecans, and cold butter in a small bowl until mixture is grainy and comes together. Cover and chill until ready to use. This can be done up to 3 days in advance.
  • Wrap each sweet potato in foil and roastat 400F for about 1 hour, or until potatoes are easily pierced by fork and very soft. Actual bake time depends on size of potatoes. Let cool enough to handle. Remove sweet potato skins, and mash potatoes well in a large bowl.
  • In a separate bowl, beat eggs, maple syrup, vanilla, lemon juice, and salt. Mix in the mashed sweet potatoes until smooth and incorporated. Transfer sweet potato mixture to a buttered 9×13 dish. At this point, you can wrap tightly with cling wrap and put in fridge until ready to use.
  • Sprinkle pecan topping evenly over casserole. Bake at 350F until casserole is set and topping bubbles. About 1 hour. Serve warm, and enjoy!


  • I always choose to roast sweet potatoes in the oven because I really like the deep flavor it creates. You can also cook peeled, cubed potatoes in boiling water until very tender.
  • Roasted sweet potatoes are typically quite sweet. If your roasted sweet potatoes don’t taste very sweet, you can add an additional 1/4 cup of sugar to the sweet potato mixture.
  • If you want, you can make extra crumble topping, for a thicker layer of crunch on top. Crumble topping can be made up to 3 days in advance and kept in fridge until ready to use.
  • For substitutions, variation, and serving suggestions, see original article.

    If Using canned yams instead how much would you need?

      • chewoutloud

      Allyson, I’d recommend using the fresh yams and follow the recipe as written, for the best results. Canned yams will likely yield different results from the original here. However, if you really need to use canned, I’d stick with the same amount (roughly 5 lbs)… you can convert ounces into lbs, according to your can size. Hope that helps 🙂

    How many would this feed

      • chewoutloud

      The recipe is for a 9×13 pan, so that’s the amount you’ll be making. If you’re having lots of side dishes and a main protein, this casserole will go a long way… it has fed large parties when there are many sides to choose from. If this is the sole side dish, I’d say about 10-12 ppl. It really depends on how many other dishes you’ll be having along with this.
