Our family is split on whether to use the pecans in the crumbly, candy topping or leave them out.  Whatever your preference, that’s a pretty easy change to make and it won’t affect the overall taste of the dish.  

My husband’s family has a similar Sweet Potato Souffle recipe where they use walnuts on top.  My mom prefers to use a glaze in her Citrus Glazed Sweet Potato Casserole.  All of these recipes are super delicious and make sweet potatoes taste even better!

We also like this recipe because we mashed some extra potatoes to keep aside and feed the baby.  She is just starting to eat food and it is messy and fun!  Feeding her these sweet potatoes reminded me that it might be time to pick up a mat to protect our rug and wood floor.

The pictures don’t do this recipe justice.  You’ve really got to try it for yourself!

Can Loaded Sweet Potatoes be Made in the Crock Pot?

Loaded sweet potato casserole can be made in a crock pot, however the topping will be a bit softer than when baked in the oven. The delicious taste is the same!

How to Make Loaded Sweet Potato Casserole

  1.  Boil and mash peeled and chunked sweet potatoes
  2. Grease a 9×13 baking dish and preheat oven to 350°F
  3. Mix sugar, butter, eggs, vanilla and milk into potatoes and spread in an even layer in the baking dish
  4. Mix the crumbly topping ingredients together: melted butter, sugar, flour and chopped pecans.  The mixture should be crumbly.  Sprinkle as evenly as possible over potatoes.
  5. Bake for 30 – 35 minutes until the topping is lightly browned.  Cover with foil and keep in warming drawer on medium or low for up to two hours if needed.

Recipe Tips

  • Pots with boiling water and potatoes create foam and easily boil over, so don’t fill over 2/3 full. It’s better to use a large pot or two medium pots than have a big mess on the stove to clean up.
  • Sugar can be reduced by up to half if desired, but of course the recipe won’t be quite as decadent.
  • Food safety is very important to keep in mind – adding a little extra milk and butter will help the potatoes hold at a warm temperature and stay moist if needed.
  • Can be held on keep warm for up to two hours, but keep thick paper towels or thin tea towel under the lid to help absorb moisture.

Detailed Step-By-Step Instructions

Wash sweet potatoes, then peel and cut into large chunks. Boil for 15 – 25 minutes until fork tender. Drain and pour into a large mixing bowl to mash.

Once potatoes are mashed well sprinkle granulated sugar. Then slice softened butter over warm potatoes so it begins to melt and is easier to mix in. Beat until mixture is smooth.

Then add milk, vanilla and eggs. It’s preferable to lightly beat eggs, but not an absolute requirement. Beat again for a few minutes until well mixed.

Mix together crumbly topping ingredients.

Once the potatoes are warmed through stir well and then sprinkle brown sugar and pecan topping mixture over the top. Add a thin towel to the top of the crock pot underneath the lid to help absorb moisture and cook on low for another hour. Once the potatoes are hot through to the center and the topping has baked on the casserole is ready to enjoy!

Can This Casserole Be Made Ahead of Time?

The mashed sweet potato layer may be prepared ahead of time and poured into a lined crock pot. Then tie the crock pot liner up with a twist tie or rubber band and store the liner in the refrigerator. Leave the crock out at room temperature to save heating time, save room in the fridge and to prevent cracking.

Add 1 to 1 1/2 hours of cook time on low to warm the potatoes through. Stir a couple times to ensure a consistent temperature before adding the crumbly candy topping. Be sure to add a tea towel under the lid to help absorb moisture during this step.
