Instant Pot Sweet Potato Casserole

Instant Pot Sweet Potato Casserole is a fluffy souffle topped with delicious and crunchy candied pecan topping. Made from start to finish in your electric pressure cooker.

This Instant Pot sweet potato casserole is a hybrid between my healthy sweet potato casserole, healthy mashed sweet potatoes and candied pecans topping I “borrowed” from the arugula beet salad.

A lot of sweet potato casseroles are finished with a marshmallow topping but we love the added crunch from the pecan streusel. It’s so delicious, it’s practically a dessert!

Ingredients for Instant Pot Sweet Potato Casserole

A small handful of everyday staples is all you need to make this Instant Pot sweet potato casserole recipe.

It may be a holiday favorite, but you can make this tasty side any time!

• Sweet potatoes: Choose fresh sweet potatoes that are firm with red, brown, or light skin and make sure there is no discoloration or root growing off of them.
• Butter: I used unsalted butter but you can swap with coconut oil, ghee, or vegan butter. If using salted butter I recommend decreasing the amount of extra salt.
• Whole milk: Helps make the mashed sweet potatoes creamy. I like whole milk but you can also use almond milk, soy milk, oat milk, coconut milk from the carton, or any plant based milk for a dairy-free version.
• Maple syrup: Liquid sweetener is divided between the sweet potatoes and pecan topping. Pure maple syrup is best for flavor, honey can be used as well.
• Seasoning: Cinnamon, pure vanilla extract, salt, pepper, and dried rosemary.
• Pecans: You’ll need 1 cup coarsely chopped nuts.

How to Make Sweet Potato Casserole in Instant Pot

Here’s a quick overview of how to make sweet potato casserole in Instant Pot using any electric pressure cooker, I used my 8 quart Instant Pot.

There is a full recipe card below with measurements and instructions.

• Toast pecans: Sauté nuts until fragrant, stirring occasionally. I have to say it takes about 7 minutes. Just like preheating Instant Pot after you press Sauté and until display says Hot takes 3-4 minutes.
• Make pecan topping: Add rosemary, maple syrup and stir until well coated. Transfer to a bowl and press Cancel button on your Instant Pot.
• Cook sweet potatoes: Add water, sweet potatoes, and salt. Liquid will not and should not cover the potatoes. Cook on high pressure for 10 minutes and then release pressure using Quick Release.
• Make sweet potato souffle: Drain sweet potatoes very well. Then add butter, milk, maple syrup, cinnamon, vanilla extract, salt, pepper. Use a potato masher to mash until smooth.
• Assemble: Transfer sweet potato mixture to a square 8 x 8 baking dish, level with spatula and sprinkle with pecan topping.

Can I Substitute Yams for Sweet Potatoes?

Yes and no. People often get sweet potatoes and yams mixed up but they each have a different look and taste.

Red orange skinned sweet potatoes often are labeled “yams” at grocery stores in North America. Although yams are entirely different, they are rarely found in North American grocery stores.

Sweet potatoes have a smooth reddish-brown skin and their orange flesh is soft and sweet when cooked. True yams have a rougher dark brown skin comparable to tree bark, their flesh is a lighter beige and they are more dry and starchy like a regular potato with an earthy, neutral taste.

So use sweet potatoes only and more likely you won’t find true yams in a store near you, they are in specialty stores.

Should I Bake It in the Oven?

We enjoy this Instant Pot sweet potato casserole as is, that’s why I didn’t add an egg. The inside is fluffy and topping is crunchy. To me personally, baking this yam casserole for another 30 minutes defeats the purpose of making it in Instant Pot all together.

But you can. Just add an egg to the mixture and bake without topping for 20 minutes at 400 degrees F. Then add the topping.

More Tips for Best Results

• Use cold water: Cook potatoes in cold water. The potato starch reacts as soon as it touches warm or hot water which leads to uneven cooking.
• To add marshmallow topping: Are you team marshmallow? Add marshmallows with or without the pecans, you will have to bake it. After you’ve transferred the sweet potato mixture to the baking dish, add marshmallows on top and bake at 350 F for 20 – 30 minutes until melted and browned. Then sprinkle with pecans, if you like, and serve.
• Other nuts: You can substitute walnuts for pecans.
• Drain sweet potatoes well: Avoid a watery Instant Pot sweet potato casserole by draining the potatoes really well.
