- Dutch oven
- blender
- wooden spoon
Ingredients:
- 12 ounces sweet potato (1 medium-large sweet potato)
- 1 ½ tablespoon mild olive oil, divided into 1 tablespoon and ½ tablespoon
- ½ teaspoon salt, divided into ⅛ teaspoon and ⅜ teaspoon
- ⅛ teaspoon ground black pepper
- 3 tablespoons minced yellow onion (you need about ⅓ of a small onion for that)
- 1 Andouille sausage* (about 3 ounces)
- 2 cups cold water
- ⅛ teaspoon ground clove
- ⅛ teaspoon ground allspice
- ⅛ teaspoon ground nutmeg
- 2 tablespoons heavy cream, more to taste
Instructions:
- Heat the oven to 400 degrees F.
- Peel the sweet potato, then cut into ¾-inch cubes.
- In a large bowl, toss the sweet potato cubes with 1 tablespoon oil, ⅛ teaspoon salt and the pepper.
- Transfer the sweet potato cubes to a baking sheet and spread into a single layer. Roast in the oven until soft and starting to brown (about 25 minutes). Stir the cubes around halfway through the baking time.
- While the potato is in the oven, prepare the remaining ingredients: Dice the onion (you should get about 3 tablespoons) and cut the sausage into bite-sized chunks.
- Heat the remaining ½ tablespoon oil in a Dutch oven. Stir in the sausage and cook until browned (about 4 minutes).
- Move the browned sausage to a bowl and set aside. Leave the oil in the Dutch oven.
- Add onion and saute until starting to soften (2-3 minutes). Turn the heat off.
- Let the potato cubes cool for a few minutes after you take them out of the oven, then transfer to a blender. Add the sauteed onion and the water. Hold down the blender lid and blend into a smooth puree.
- Transfer the puree back into the Dutch oven and add the browned sausage.
- Turn on the heat and stir in the remaining ⅜ teaspoons salt, the clove, the allspice and the nutmeg. Bring to a simmer, then turn the heat off and stir in the cream. Season to taste with more salt and more cream (if desired).
