How to Make Sweet Potato Casserole with Pecan Streusel

This entire recipe can be assembled ahead of time and baked before serving. If serving immediately, start by preheating oven to 375 degrees.

Step 1: To start, peel and dice the sweet potatoes into large chunks. Then, place in a large pot and cover with cold water. Bring to a boil and reduce to simmer. Cook until the sweet potatoes are fork tender, about 10 minutes. Drain and return to pan.

Step 2: Next, mash the sweet potatoes until your desired consistency. You can use a potato masher, ricer, or even a handheld mixer to achieve the desired texture. Then, add in the brown sugar, butter, vanilla, cinnamon and nutmeg, and salt to taste. Stir to combine.

Step 3: Spread sweet potato mixture into a coated 9 x 9 baking pan or casserole dish. If baking immediately, preheat oven to 375 degrees.

Step 4: Lastly, make the pecan streusel topping by stirring together the flour, brown sugar, and pecan pieces. Add in the cubed butter and combine using your hands and squeezing the mixture together. Sprinkle the crumble topping over the sweet potatoes.

At this point you can either bake immediately or refrigerate until ready to bake. (Casserole can be made up to 2 days in advance.) Bake for 35 minutes. If the topping gets too brown, just cover with foil.

Expert Tips and FAQs

  • Cut the sweet potatoes into similar sized chunks so that they cook evenly.
  • Pour cold water into the pot and then bring to a simmer. Starting in hot water could cook the outside of the sweet potatoes before the inside has a chance to cook.
  • Return the cooked sweet potatoes to the hot pot to mash. The heat will help evaporate any excess liquid in the potatoes.
  • For a less sweet dish, reduce the amount of brown sugar in the mash or omit it entirely.
  • Refrigerate the entire sweet potato casserole with pecan streusel for up to two days before baking. Add additional cooking time to the casserole and make sure the center of the dish is warm before serving.
