“Best sweet potato casserole ever!!! This will be the only way I’m going to make sweet potato casserole from now on!!!” – Anke

“Most sweet potato dishes seem boringly similar. This one provides a few interesting surprises with coconut and pecans. Delicious!” – Christine

“I have made this casserole for the last couple of years & each time I’m asked to double the recipe. It’s the only way I make sweet potatoes for Thanksgiving and Christmas. Yes, it’s THAT yummy!” – Cherie

The Perfect Holiday Side Dish


I’ve tried a lot of versions over the years, and this Sweet Potato Casserole with Pecans is the one my family asks me to double for Thanksgiving and Christmas. It’s very similar to the beloved sweet potato casserole at Ruth’s Chris Steak House, but we take it over the top with toasted coconut in the pecan crumble. That hint of toasty sweetness is what makes guests ask, “What did you put in this?!”

Some of my favorite Holiday pairings: Roasted Turkey or prime rib, Honey Baked Ham or Cranberry Chicken, Homemade Mashed Potatoes, Green Bean Casserole, Creamed Spinach, fresh Orange Cranberry Sauce, classic Sausage Stuffing, and warm Dinner Rolls. And you have to finish it off with a slice of Pumpkin Pie.

Key Ingredients

Ingredients to make sweet potato casserole with pecan topping including milk, brown sugar, vanilla, flour, sweet potatoes, salt, egg, butter, pecans and coconut flakes.
  • Sweet Potato Layer – Sweet potatoes (you can use canned or fresh, I usually go for canned out of convenience), milk, brown sugar, melted butter, egg, vanilla, salt.
  • Coconut Pecan Layer – Brown sugar, chopped pecans, shredded coconut, flour, melted butter.
  • Optional Additions – For a little more spice variation you can add a little cinnamon, nutmeg, or pumpkin pie spice to the sweet potato layer.

How to Make Sweet Potato Casserole with Pecans

Glass mixing bowl with sweet potato mixture and whisk attachment.
  1. Mix the base: 350°F. Grease a 9×9-inch baking pan. In a large bowl, combine sweet potatoes, milk, brown sugar, melted butter, egg, vanilla, and salt. Beat until light and fluffy.

  1. Toast & toss the topping: In a dry skillet, toast coconut 2-3 minutes until lightly golden (optional but recommended). In a small bowl, stir brown sugar, pecans, coconut, flour, and melted butter until crumbly.

Recipe Tips

  • For fluffiest texture: Use a hand or stand mixer and beat the base for 1-2 minutes.
  • Avoid sogginess: If using canned sweet potatoes, drain very well; if boiling fresh, let steam off completely before mashing.
  • Double it: Make a 9×13 pan by doubling everything; bake 40-45 minutes.
  • Keep the crunch: Reheat in the oven (not microwave) so the pecans stay crisp.
  • Transporting: Bake in a disposable pan or assemble at destination; add topping just before baking.

Frequently Asked Questions

Are canned yams and sweet potatoes the same?

Yes, canned candied yams sold in U.S. grocery stores are actually sweet potatoes. This is what we use in this recipe. True yams and sweet potatoes are different in color, taste, and texture.

Can I make this Sweet Potato Casserole Gluten-Free?

Yes, there is only gluten in the topping. To make this recipe gluten-free, substitute coconut flour, rice flour, or any other favorite gluten-free flour mixture in place of the white flour.

Nut-free option?

Use pumpkin seeds or sunflower seeds for crunch, or make a coconut-oat streusel and skip nuts entirely.

Can I make this casserole Dairy-free or egg-free?

See substitutions above; plant milk + plant butter work well. For egg-free, add 1 Tbsp cornstarch to help set.

Can I use fresh sweet potatoes instead of canned, and how many do I need?

Yes. Use 3-4 medium sweet potatoes (about 1½-2 lb raw) to yield roughly 3½ cups mashed. Peel and cube, then boil 12-15 minutes (until fork-tender) or roast at 400°F for 35-45 minutes for deeper flavor. Drain/steam off moisture before mashing so the base isn’t watery.

How smooth should the base be, mashed or fully whipped?

It’s your call. For a classic, slightly rustic texture, mash by hand until mostly smooth. For that custardy, restaurant-style finish, beat with a hand mixer 1-2 minutes until light and fluffy. Avoid a food processor, it can overwork the starches and turn the potatoes gummy.

Can I cut back the sugar without affecting texture? How much?

Absolutely. The base is flexible, reduce the ¼ cup brown sugar to 2 Tbsp without issues. For the topping, sweetness helps crispness; you can drop the ½ cup to ⅓ cup, but going lower may reduce crunch. Balance by using unsweetened coconut and a touch more vanilla or a pinch of cinnamon.

Can I use maple syrup or honey in the base? How do I adjust liquids?

Yes. Swap the ¼ cup brown sugar for 3 Tbsp maple syrup or honey and reduce the milk by 1-2 Tbsp to compensate for added liquid. (Optional: add ½ tsp molasses to mimic brown sugar’s caramel notes.) Keep brown sugar in the topping for the best crumble; liquid sweeteners there tend to make it softer unless you add extra flour and chill the mixture.

Make Ahead and Storage

Make ahead: Assemble (add topping or store topping separate), cover, and refrigerate up to 24-48 hours. Bake uncovered straight from the fridge, adding 5-10 minutes.

Fridge: Cover and refrigerate leftovers in an airtight container up to 5 days.

Reheat: 350°F for 15-20 minutes, uncovered, until warmed through.

Freeze: Assemble without the topping and freeze up to 2 months. Thaw in the fridge overnight, add topping, and bake.

    Am diabetic and this is pretty high sugar; but, I think I will try anyway. I love sweet potatoes, but never tried them in casserole. I think I’ll love it.

    I’ve served a similar style dish every year for Thanksgiving and Christmas for most of my adult life but came across this version and had to try it out and it’s just what my dish needed to give it the extra kick.

    I haven’t actually made this recipe but have made one very similar. Topping has crushed corn flakes, melted butter, brown sugar and chopped nuts. I much prefer this topping compared to marshmallows!
