Sweet Potato Brioche French Toast Recipe (2024)

1. For the Brioche: Obtain about 4 large or 5 medium sweet potatoes. Place rack in center of oven. Preheat oven to 400°F (200°C). Gently scrub and pat dry sweet potatoes, then pierce all over with paring knife and place on lined sheet pan. Bake until juices caramelize and potatoes are baked through, 40-60 minutes. Allow to cool slightly, then peel off skin and cut into chunks, removing any blemished or overly stringy spots. Cut into large chunks and purée completely in a food processor. Measure out 1 cup, then another 1 1/4 cup for the filling and syrup, which can be refrigerated.

   Note: If you don't have a food processor, the best way to purée the sweet potato is by forcing the warm baked potato chunks through a strainer. Press and scrape the purée with a plastic bowl scraper or sturdy spatula; you'll find that the tougher fibrous bits stay on the inside of the strainer and you can easily scrape the smooth purée from the bottom.

2. Combine warm water and yeast in bowl of stand mixer and set aside to dissolve, about 2 minutes. Add 1 egg and 1 1/8 cup flour and mix on low speed with paddle until fully combined, then set aside and allow to rise until doubled, about 30 minutes. Add sugar, salt, remaining eggs and flour, and sweet potato purée and mix on low until completely combined, scraping bowl and beater as needed. On low speed, gradually add butter until completely combined, scraping as needed. Once all butter is incorporated and dough is uniform, transfer to a clean medium bowl and wrap tightly with plastic. Refrigerate at least 2 hours, up to 24 hours.

3. Set rack in center of oven. Preheat oven to 425°F (220°C). Brush insides of two loaf pans with butter. Divide dough in half. On a lightly floured surface, roll each piece of dough into an 8x12 inch rectangle. In a small mixing bowl, whisk together the sweet potato purée and egg yolks for the filling. Spread half the filling evenly onto each rectangle, then roll the rectangles tightly as you would for a jelly roll cake, creating two 8 inch rolled logs. Place each seam-side down into prepared pans and allow to rise until doubled in size, about 30 minutes. Once risen, melt a couple of pats of unsalted butter and brush gently onto each loaf. Bake for 15 minutes, then turn, brush with butter again and lower temperature to 350°F. Bake for 20-25 minutes. Allow loaves to cool fully before turning out. Wrap cooled loaves tightly in plastic and refrigerate or freeze until ready to use.

4. For the French Toast: Set rack in center of oven and preheat oven to 375°F (190°C). Combine milk and butter in small saucepan and place over medium heat. Once butter is fully melted, add sugar, salt, vanilla and Allspice dram and whisk to dissolve sugar. Remove from heat. Place egg yolks in small mixing bowl and gradually pour in hot liquid, whisking constantly. Pour soak into shallow pan (a pie pan is great for this) and slice brioche into inch-thick pieces. Soak each slice of bread in liquid for 30 seconds on each size, then set on a rack over a baking sheet. Melt a couple pats of butter in a large frying pan, once foamy add two pieces of soaked bread and cook until golden, 2-3 minutes. Flip and repeat with other side, then transfer to rack and bake 5 minutes. Repeat to cook as many pieces as desired.

   Note: Soak will hold for up to 3 days in the refrigerator if you want to make it ahead or if you have leftovers. Whisk before using to break up any lumps of butter.

5. For the Syrup: Combine sweet potato purée, syrup, orange juice, allspice and salt in small mixing bowl and whisk to combine. Pour generously over warm French toast.
