Thanksgiving isn’t Thanksgiving without sweet potatoes!

But unlike roasted sweet potatoes or slow cooker sweet potatoes, this recipe for sweet potato crunch casserole is buttery sweet and more of a dessert than side dish. *Wink*

This recipe works because it:

  • Saves you from peeling and chopping. By using the Instant Pot to cook the potatoes, you’ll avoid using a knife.
  • Limits the dishes you’ll need. The potatoes cook and get mixed in the same Instant Pot insert.
  • Frees up the oven and stove for awhile. We all know how many recipes go into making Thanksgiving dinner. This recipe lets the Instant Pot do the hard work for awhile.
  • Is absolutely scrumptious! The rich, sugary topping combined with the creamy potato filling makes you want to go back for seconds and thirds.

Step-by-Step Instructions

Sweet potato crunch ingredients including brown sugar, butter, egg, and sweet potatoes.

CLEAN and dry 3 medium sweet potatoes. Poke them several times with a fork.

PLACE them on a trivet in the Instant Pot and pour 1 cup of water over them.

Washed sweet potatoes in Instant Pot insert with water at bottom.

LOCK the lid on the Instant Pot and set the valve to sealing. Use the pressure cook button on high and set the timer for 25 minutes.

WHILE the potatoes are cooking, mix together 3 tablespoons of softened butter, 3 tablespoons of flour, 3/4 cup of brown sugar, 1/2 cup chopped pecans, and 1½ tablespoons of cinnamon. Set aside.

Small mixing bowl with brown sugar, pecans, butter, flour and cinnamon.

ONCE the timer has gone off, allow the pressure to naturally release for 10 minutes.

CAREFULLY remove the sweet potatoes from the pot and place on a plate to cool for 3-5 minutes.

Cooked sweet potatoes with skins coming off on plate surrounded by various ingredients.

DUMP the water out of the Instant Pot insert and remove the trivet.

ONCE the potatoes have cooled slightly, peel the skins off the sweet potatoes and place the potatoes back in the insert.

Mashed sweet potatoes in metal bowl with various ingredients also on table.

MASH the potatoes and then mix in 1/4 cup softened butter, 1/2 teaspoon of salt, 1 egg, 1/2 cup brown sugar, 1 teaspoon of vanilla, 1/2 teaspoon cinnamon, 1/4 teaspoon nutmeg, and 2 tablespoons of half and half.

Recipe Tips and Substitutions

Since sweet potatoes aren’t all the same size, you may have to adjust the cooking time in the Instant Pot depending on how big or small the sweet potatoes are. You can use this awesome guide for cooking perfect Instant Pot sweet potatoes.

To ensure that the middle of your sweet potatoes cook through, you can cut each sweet potato in half, but only if you want to pull out a knife.

If after the recommended cooking time, your sweet potatoes aren’t cooked all the way through, you can put the lid back on the Instant Pot and add 5 more minutes of cook time, or you can start mashing the sweet potatoes and pull out the uncooked pieces. Add those pieces to a microwave safe dish with a little water, cover, and cook for 2-3 minutes on high.

If you STILL have a few hard potato pieces and don’t want to spend any more time, the potatoes will soften up in the oven during the 30 minute cook time. I like some texture in my potatoes, sweet or savory, so having a few larger potato pieces doesn’t bother me. But if you want absolutely creamy potatoes, you can continue with the microwave or Instant Pot method mentioned above to cook any hard pieces.

The sweet potatoes will be pretty messy when they’re done in the Instant Pot so you’ll want to use some oven mitts or two sets of tongs to remove them.

For extra fine pieces, you can pulse whole or chopped pecans in a food processor a few times.

If your topping is browning too quickly in the oven, you can cover the dish with a foil tent to slow the browning.

This recipe is perfect for Thanksgiving, but it also goes well with pulled pork, steak, tri-tip, or brown sugar salmon.

Good overall idea but with all that brown sugar & cinnamon in the topping, there really is no need for brown sugar in the sweet potatoes. Sweet potatoes are so nice & sweet without a thing else in them! However this recipe is nice with the butter (grass fed) of course in the potatoes, got to have that. & a punch of salt & just a scant pinch of nutmeg are good as well. But I would skip the brown sugar, cinnamon & vanilla. The vanilla is just not a flavor that goes with sweet potatoes, changes it too much. Same goes for the cream. But with leaving the topping as instructed, the dish is fantastic!
