Why I love this casserole:
The Topping – The topping on this casserole is made with butter, pecans, flour, and brown sugar. It’s so much better than the marshmallow topping on sweet potato casserole (in my opinion!). Make-Ahead – Want a stress-free Thanksgiving day? This whole casserole (as well as more of my Thanksgiving recipes) can be made a day or two in advance. Check out my Make Ahead Instructions at the end of the post for details! Crowd Pleaser – This is a HIT with family and friends every single year. The potatoes are creamy, and the topping adds the perfect crunchy texture. It will become a new staple on your Thanksgiving table!
Sweet Potato Casserole with Marshmallows:
To add a marshmallow topping instead, simply top the casserole with a layer of miniature marshmallows and bake for about 25 minutes, or until the marshmallows are puffy and browned. You could also prepare this dish half and half with half pecan crumble mixture and half marshmallows. For this method, cook with half of the crumble for about 15 minutes first, then remove from the oven, cover the other half of the casserole with marshmallows and continue baking. Make Filling: Add eggs, evaporated milk, vanilla, sugar, salt, and butter and mash everything together until smooth. I start with a potato masher, and then use an electric mixer on low speed, for about 45 seconds, to get the mixture smooth (without over-mixing). Smooth into casserole dish. Add Pecan Topping: Combine the topping ingredients– butter, chopped pecans, flour, and brown sugar–and sprinkle all over the top of your mashed sweet potato mixture. Bake: Place in the oven and bake for 35-40 minutes. Serve this sweet potato casserole with pecans alongside your favorite Thanksgiving recipes!
Make Ahead, Storing, and Freezing Instructions:
To Make-Ahead: You can prepare this easy sweet potato casserole recipe 1-2 days in advance. First make the filling and smooth into your baking dish. Make the topping, but store seperatly. Add topping before baking. Here are some other great Make-Ahead Thanksgiving recipes. To Store: Store sweet potato casserole covered in the refrigerator for 4-5 days. To Freeze: Prepare the sweet potato casserole completely, but don’t bake it. Cover with a double layer of aluminum foil and freeze for up to 3 months. Thaw overnight in the refrigerator. Allow it to come to room temperature for 30 minutes on the counter before baking.
