Sweet Potato Casserole Recipe: Ingredients & Substitutions 

I recommend making this Thanksgiving sweet potato casserole as written, however here are some possible substitutions. 

• Salted Butter. Unsalted butter can be used in place of salted butter, you may just need to increase the salt. 
• Eggs. I do not recommend making a substitution for the egg. 
• Whole Milk. Half and half, heavy cream, or 2% milk can be used in place of whole milk. Fat content is important to the final outcome of this recipe.
• Brown Sugar.  light or dark brown sugar can be used with great results. 
• All-purpose flour. For a gluten-free version, use an all-purpose gluten-free flour. 
• Pecans. Walnuts are a great substitute for pecans. 

How to make Sweet Potato Casserole

This sweet potato casserole is easy to make, but as always we’ll walk through the process step-by-step, and don’t forget to watch the video. 

Roast the sweet potatoes

To easily roast sweet potatoes, wash and pierce them with a fork. Then, individually wrap the potatoes in foil and put them on a baking sheet. You can roast them directly on an oven rack, just be sure the foil is completely closed so there’s no dripping.

Bake until the sweet potatoes are tender and compress when touched. The baking time depends on how thick your potatoes are. Check at 40 minutes if they are small.

Open foil and set the sweet potatoes aside to cool.

Make the Pecan Crumb Topping

While the sweet potatoes are roasting, make the crumb topping. In a medium bowl, use a fork or pastry cutter to combine butter, brown sugar, flour sea salt and cinnamon until a coarse meal forms.

Add pecans and stir until evenly distributed in the mixture. Set aside.

Rice (or mash) the sweet potatoes

Scoop the slightly-cooled sweet potato flesh out of the skins and transfer to a large bowl. Use a potato ricer to mash the cooked sweet potato flesh – discard any stringy pieces left in the ricer.

Note: you can use a potato masher but I don’t not recommend it, as sometimes the flesh of a sweet potato is stringy, and a ricer will remove any unpleasant texture. Or you can put the sweet potato, along with the other filling ingredients, in the container of a blender and blend until smooth.

Make the Sweet Potato Casserole Filling

Once the sweet potato is riced/mashed, add eggs, butter, brown sugar, maple syrup, sea salt, cinnamon, ginger and nutmeg and stir to combine.

Putting it together

Decrease oven temperature to 350 degrees F and grease an 8×8” baking dish. Pour sweet potato mixture into the prepared pan and smooth out the top so it is flat and even.

Sprinkle the pecan crumb topping evenly over the top of the sweet potato mixture, gently pressing it into the mixture. 

Bake & Cool

Bake in preheated oven until the top is slightly puffed and the topping is lightly browned. Let cool slightly and serve.
