Sweet Potato Rosette Tart

Plant-based | Stunning presentation | Fall dessert | Thanksgiving-worthy

A stunning tart that uses two types of sweet potatoes for a beautiful end result. Orange sweet potatoes are mashed with zesty orange juice and pumpkin pie spice for a custard-like filling, while steamed purple sweet potato petals are arranged in an eye-catching rosette pattern. The nutty oat and almond crust contrasts beautifully with the earthy sweetness.

Aquafaba Whipped Cream1 recipeOptional

  1. Make crust: Preheat oven to 400°F. In food processor, combine oats, flaxseed meal, almond butter, and 1¼ tsp pumpkin pie spice. Pulse until combined. With processor running, slowly add milk until mixture clings together and is slightly moistened. Press onto bottom and up sides of 10-inch tart pan. Bake 8 minutes. Remove and reduce oven to 350°F.

  2. Make orange sauce: In small saucepan, combine orange juice, dates, and remaining ¼ tsp pumpkin pie spice. Bring to boiling; reduce to gentle boil 7-10 minutes until reduced by half (to ½ cup). Set aside 2 tablespoons.

  3. Make filling: Combine mashed orange sweet potatoes, arrowroot powder, and 6 tablespoons orange sauce. Pour into partially baked crust.

  4. Bake: Bake 35-45 minutes until filling is set, covering loosely with foil if needed to prevent overbrowning. Cool on wire rack.

  5. Steam purple potatoes: Place slices in steamer basket over boiling water. Steam 3-5 minutes until tender.

  6. Decorate: When tart is slightly cooled, arrange purple potato slices in concentric circles on top. Brush with reserved orange sauce. Sprinkle with almonds.

  7. Serve: With Aquafaba Whipped Cream if desired.


Slice thickness: Purple potatoes should be very thin (⅛ inch) for easy arranging

Make ahead: Bake tart up to 1 day ahead; add rosette just before serving

Color pop: The purple potatoes add stunning visual contrast
