Pecan Crumble Sweet Potato Casserole Ingredients

  • Sweet potatoes – wash, then peel and cut into large cubes. The smaller the cubes, the faster they’ll cook.
  • Evaporated milk – you can use cream or half and half, just make sure it’s nice and cold, straight from fridge to help cool down the sweet potatoes.
  • Brown sugar – light or dark brown sugar is fine for sweet potato casserole. Used in both the casserole filling and the pecan crumble topping, this adds a rich, warm sweetness (more so with dark brown sugar).
  • Eggs
  • Vanilla, Salt, Cinnamon – this combo enhances the cozy, comforting sweetness of sweet potatoes.
  • Flour – use all-purpose flour.
  • Butter – use unsalted butter for both the filling and topping, just make sure it’s softened for easy melding.
  • Pecans – chopped finely for smaller crumble pieces, larger for bigger crumbles.

Tips for the Best Pecan Brown Sugar Topping

This tried and true recipe to make topping for sweet potato casserole is crunchy, sweet, and nutty.

  • Use butter softened so much it’s spreadable and almost melted—cold butter will be difficult to cut; melted butter is too wet.
  • Use a fork and/or pastry cutter to mostly incorporate the butter and brown sugar mixture.
  • Then, switch to using gloved hands. The gloves provide a little heat insulation and make cleanup easier!
  • With gloved hands, gently massage the mixture to evenly mix it and squeeze periodically to create crumbles/pebbles of topping. It should look like moistened sand.
  • As you massage, the heat from your hands will gently, partially melt the butter into the flour, yielding the best crumble. Without gloves, the butter would melt too much.

Sweet Potato Casserole with Marshmallows

To make sweet potato casserole with marshmallows, skip the pecan crumble topping and top with 2 cups mini marshmallows. Bake for 25 minutes or until marshmallows are golden brown and puffed up.

Make Ahead Sweet Potato Casserole

For make ahead sweet potato casserole, make the sweet potato filling and smooth into baking dish, cover and refrigerate. Make crumble topping and keep in a separate container; add before baking. Refrigerate for 1-2 days in advance.

Make Ahead Freezing Instructions

Assemble sweet potato casserole without the topping, then cover the sweet potato layer in plastic wrap. Assemble brown sugar pecan topping and place in a zip top bag. Place bag over the plastic wrap. Double wrap the casserole in foil. Freeze for 2-3 months. Thaw on counter for 30 minutes or overnight in the fridge. Break up topping as needed, then sprinkle evenly over casserole. Bake as normal, potentially adding 5-10 more minutes to account for the casserole being chilled.

Smooth and creamy filling with nuts and brown sugar for the perfect Easter and Christmas side dish.

Tips

  • For tips on making the best pecan crumble, see above.
  • Use cold, straight from the fridge evaporated milk and pour it evenly over the steaming sweet potatoes, this will help prevent the eggs from cooking.
  • Finish the sweet potato filling with a hand mixer—this will ensure a smoother, creamier texture, something the potato masher can’t do.
  • Don’t worry about teeny, tiny chunks of sweet potato—they won’t be noticeable once baked.
  • Cook sweet potatoes until tender: when cooking sweet potatoes in a pot, test doneness by retrieving a cube and placing on a plate: if it smooshes and flattens easily, it’s ready to drain and mash!

Instructions 

  • Cook Sweet Potatoes: Place sweet potato cubes into a large stockpot. Fill with water until sweet potatoes are submerged. Cover and bring to a boil. Simmer and cook until fork tender (nice and soft, so it’s easy to mash), about 10-15 minutes.* Drain very well.
  • Prepare Filling: Transfer sweet potatoes into a large mixing bowl. Mash with a potato masher until mostly smooth. Pour cold milk evenly over potatoes to help them cool down. Add brown sugar, butter, eggs, vanilla, salt, and cinnamon to the bowl. Using a hand mixer, mix very well until smooth (a few tiny chunks will remain). Grease a 9×13” pan. Transfer filling into pan, smoothing into an even layer. Preheat oven to 350°F.
  • Make Topping: Add butter, flour, light brown sugar, and pecans to a medium bowl. Use a fork or pastry blender to toss until well mixed, then use gloved hands to mix and periodically gently squeeze the mixture until crumbles form—it should look like moistened sand crumbles. Sprinkle topping evenly over filling.
  • Bake for 35-40 minutes, until topping is crisped and lightly golden brown and the sweet potatoes are hot throughout. Enjoy! Storing instructions below.
