What is the difference between a sweet potato and a yam?

In the United States the terms “yam” and “sweet potato” are often used interchangeably, but they are different vegetables. True yams are starchy, with rough brown skin, and are commonly eaten in parts of Latin America, West Africa, the Caribbean, and Asia. Sweet potatoes are a New World root vegetable with smoother, reddish skin and a sweeter, creamier interior. Most produce labeled “yams” in U.S. supermarkets are actually sweet potatoes.

How to make Slow Cooker Sweet Potato Casserole (without marshmallows!)

ingredients being prepped for Slow Cooker Sweet Potato Casserole

Start by peeling about 3 pounds of sweet potatoes (roughly 3–5 potatoes, depending on size). Cut them into 1-inch cubes and place them in a large slow cooker.

Stir together brown sugar, half-and-half, melted butter, pure maple syrup, vanilla, kosher salt, and a pinch of cayenne, then pour and mix with the sweet potatoes until combined.

For the pecan crumble, toast 1 cup of pecans until fragrant, then combine them with brown sugar, all-purpose flour, melted butter, and a pinch of salt. Sprinkle the mixture evenly over the potatoes.

Cover and cook on high for 4–5 hours, until the center potatoes are very tender and the pecan crumble is golden. Let the casserole rest for 15–30 minutes after cooking so the caramel sauce thickens to the right consistency.

Can I use canned yams or sweet potatoes instead of fresh for this recipe?

No. Canned yams or sweet potatoes are already cooked and will not yield the same texture or flavor in this slow cooker casserole. This recipe is designed for raw, fresh sweet potatoes from the produce section.

Ingredients

  • 3 pounds sweet potatoes, peeled and cubed to 1″
  • 1/2 cup brown sugar
  • 1/2 cup half and half
  • 1/4 cup butter, melted
  • 1/4 cup 100% pure maple syrup
  • 1 teaspoon vanilla extract
  • 1 teaspoon kosher salt
  • 1/8 teaspoon cayenne pepper (optional)

Pecan Crumble Crust

  • 1 cup pecans, toasted and chopped
  • 2/3 cup brown sugar
  • 1/2 cup all-purpose flour
  • 1/4 cup butter, melted
  • 1/4 teaspoon kosher salt

Instructions

  • Line or spray a large slow cooker with non-stick spray.
  • Add the peeled and cubed sweet potatoes to the slow cooker.
  • Add the remaining ingredients (brown sugar, half and half, melted butter, maple syrup, vanilla, salt, and cayenne) and stir to combine. Pat the potatoes flat.

Pecan Crumble Crust

  • Toast the pecans at 350°F for about 8 minutes until fragrant. Roughly chop if needed.
  • In a small bowl, stir together pecans, brown sugar, flour, melted butter, and salt. Sprinkle over the sweet potatoes in the slow cooker.
  • Cover and cook on high for 4–5 hours, or until the potatoes are very tender and the crumble is golden.
  • Let the casserole rest 15–30 minutes before serving so the sauce thickens to a caramel-like consistency.

Notes

Allowing the casserole to rest after cooking helps the caramel sauce thicken and cling to the potatoes.

The small amount of cayenne enhances flavor without making the dish spicy; omit it if preferred.
