Instant Pot Sweet Potato Casserole

This Instant Pot Sweet Potato Casserole features smooth mashed sweet potatoes flavored with brown sugar, cinnamon, orange zest, and vanilla. Topped with a crunchy pecan mixture and finished with miniature marshmallows browned in the oven, the casserole balances creamy, sweet, and nutty textures. Cooking the sweet potatoes under high pressure in the Instant Pot speeds up preparation while maintaining moisture for a rich, comforting side dish or dessert.

Description

The recipe begins by pressure-cooking peeled and chopped sweet potatoes with water in an Instant Pot for eight minutes, followed by quick release. Pecans are combined with melted butter, brown sugar, flour, and salt to form a crunchy topping mixture chilled before baking.

The mashed sweet potatoes are mixed with butter, brown sugar, beaten eggs, milk, orange zest, vanilla extract, cinnamon, and salt to create a smooth, flavorful base. This is spread into a baking dish and topped with the pecan mixture before baking at 350°F until nearly set.

Miniature marshmallows are added on top then baked further until melted and lightly browned, providing a sweet contrast to the spiced potatoes and nutty topping. This casserole serves as a comforting side or dessert suitable for holiday meals or family gatherings.
