Ingredients

  • Butter or cooking spray for baking dish
  • 4 pounds sweet potatoes (6-7 medium), peeled and cubed
  • Salt for cooking potatoes plus 1/4 teaspoon
  • 1 stick unsalted butter
  • 4 large eggs beaten
  • 1 cup sugar
  • 1 cup whole milk
  • 3 tablespoons self-rising flour
  • 1 teaspoon vanilla extract
  • 1 teaspoon almond extract
  • 1 teaspoon coconut extract

Topping

  • 1/2 cup chopped pecans
  • 1/2 cup brown sugar
  • 1/3 cup all-purpose flour
  • 2 tablespoons butter

Instructions

  • Preheat oven to 350 degrees. Butter or spray a 2-quart baking dish. Set aside.
  • Cook sweet potatoes in salted water to cover until fork-tender, approximately 20-25 minutes.
  • Melt butter in a large bowl. (I do this over the pot of potatoes as they're boiling. Be careful to not let the potatoes boil over; remove the butter as soon as it's melted.)
  • Drain well, then process the potatoes through a food mill or potato ricer INTO the melted butter. Stir to blend.
  • Beat the eggs then whisk in the sugar, milk, flour, extracts and 1/4 teaspoon salt until smooth. Add to bowl with potatoes and butter and stir well to combine.
  • Transfer to the prepared baking dish. Bake for 1 hour or until fluffy and heated through in the center to 165 degrees. Place a loose piece of aluminum foil over the top if the pecans start to get too brown. Serve immediately.

Topping

  • Combine pecans, brown sugar, flour and butter in a small bowl. Sprinkle evenly over the top of the souffle.

Notes

SUBSTITUTIONS:
  • Instead of the self-rising flour, use 3 tablespoons of all-purpose flour and a pinch of baking soda.  I've used only all-purpose flour at times, and it has worked fine.
TIP:
  • When melting butter for this sweet potato souffle recipe or mashed potatoes, I place the butter in a large stainless steel bowl and melt it over the pot of potatoes as they’re boiling. However, I remove the butter as soon as it’s melted so the pot does not boil over.
MAKE AHEAD:
  • Assemble up to 2 days ahead of time and refrigerate until needed. Leave the topping off then sprinkle that over the top right before baking.
  • Let sit at room temperature while the oven preheats.
