Sweet Potato Crème Brûlée Recipe
This recipe yields five large or 6–7 small ramekins of rich, autumnal crème brûlée. It can also be served in edible sweet potato bowls for a delightful presentation, though ramekins are the standard.
Ingredients
- 6 large egg yolks
- 1/2 cup granulated sugar (plus extra for topping)
- 8 ounces cooked sweet potato (roasted and mashed for best texture)
- 2 cups heavy cream
- 1 teaspoon vanilla extract (or seeds from 1 vanilla bean)
- Pinch of kosher salt
- Optional: 1/2 teaspoon ground cinnamon or nutmeg (for added warmth)
Equipment Needed
- 5 large or 6–7 small ramekins (6-ounce capacity ideal)
- Large roasting pan for water bath (bain-marie)
- Whisk and mixing bowls
- Fine mesh strainer
- Kitchen torch or broiler (for caramelizing sugar)
Step-by-Step Instructions
1. Roast the Sweet Potato
- Preheat oven to 400°F (200°C).
- Place 1–2 medium sweet potatoes (enough for 8 oz. cooked flesh) on a baking tray and pierce skins with a fork.
- Bake for 40–50 minutes, until tender when pierced.
- Let cool slightly, then scoop out the flesh and mash until smooth with a fork or food processor.
2. Prepare the Custard Base
- In a medium mixing bowl, whisk together the egg yolks and half of the granulated sugar until pale and slightly thickened.
- In a saucepan, combine heavy cream, mashed sweet potato, vanilla extract or seeds, salt, and spices (if using).
- Heat the cream mixture on medium heat, stirring frequently, until just below a boil—it should be steaming but not bubbling.
- Slowly pour the hot cream mixture into the egg yolk mixture, whisking constantly to temper the eggs and prevent scrambling.
- Strain the custard through a fine mesh sieve into a large measuring cup or bowl to remove any bits and ensure a silky-smooth base.
3. Assemble and Bake
- Arrange your ramekins in a large roasting pan or deep baking dish.
- Divide the custard mixture evenly among the ramekins, filling each about 3/4 full.
- Carefully pour hot water into the roasting pan, around the ramekins, until it reaches halfway up their sides. This water bath promotes gentle, even baking and prevents curdling.
- Bake at 325°F (160°C) for 35–40 minutes, until the edges are set but the centers still jiggle slightly when shaken.
- Transfer the ramekins with tongs or oven mitts to a wire rack. Cool to room temperature, then refrigerate for at least 3 hours (or overnight) until thoroughly chilled and set.
4. Caramelize the Tops
- Before serving, blot any condensation from the tops of the custards with a paper towel.
- Sprinkle a generous, even layer of granulated sugar (about 1 teaspoon per ramekin) over the custard surface.
- Using a kitchen torch, carefully melt and caramelize the sugar until bubbly and golden-brown. Let stand for a minute.
- If a torch is unavailable, place ramekins under a preheated broiler and watch closely until the sugar is caramelized. Allow the sugar top to cool and harden for at least 2–3 minutes before serving.
Tips for Success
- Use Room Temperature Ingredients: Eggs and sweet potato puree should be at room temperature to ensure a smooth custard.
- Strain the Custard: Passing the custard mixture through a mesh sieve ensures creaminess by removing any grainy bits of potato or cooked egg.
- Don’t Overbake: The custards continue to cook as they cool. Take them out when the centers are still wobbly for the best texture.
- Chill Thoroughly: Refrigeration is crucial for a custard that slices cleanly and supports the crackly sugar crust.
- Caramelize Just Before Serving: For the crispiest topping, brûlée right before enjoying.
Serving Ideas & Variations
- Top with a dollop of whipped cream and a dusting of cinnamon for extra flair.
- Garnish with toasted pecans, candied ginger, or edible flowers for a stunning finish.
- Infuse the cream with
chai spices
or citrus zest for unique flavor twists. - For individual servings, bake custard in oven-safe sweet potato skins for an entirely edible presentation.
Storing and Make-Ahead
- Baked custards keep in the fridge (covered) for up to three days; add sugar and caramelize just before serving for best results.
- Do not freeze, as the custard texture may degrade and the sugar top becomes soggy.

Frequently Asked Questions (FAQs)
Q: Can I use canned sweet potato puree?
A: Yes, but ensure it is plain and unsweetened for the best flavor and texture. Homemade roasted sweet potato will provide more depth of flavor.
Q: What’s the best way to caramelize the sugar if I don’t have a kitchen torch?
A: Place the ramekins under the broiler on high, watching very closely, until the sugar bubbles and caramelizes. This may not be as even as a torch but still produces a satisfying crackly top.
Q: Can I make this recipe dairy-free?
A: Yes, you may substitute full-fat coconut milk for cream, but the texture will be slightly less rich, and flavor will change subtly.
Q: Why is my custard grainy or curdled?
A: The custard may have cooked too quickly or at too high a temperature. Be sure to use a gentle water bath and do not boil the cream before tempering into the yolks.
Q: How do I prevent the sugar top from becoming soggy?
A: Brûlée the sugar topping just before serving, and make sure the surface of the custard is dry before sprinkling on sugar.
Recipe Variations to Try
- Maple Sweet Potato Crème Brûlée: Substitute part of the sugar with real maple syrup for a deeper fall flavor (reduce sugar slightly).
- Spiced: Add ground ginger, allspice, or a pinch of clove for a festive holiday touch.
- Pumpkin Swap: Use pumpkin puree instead of sweet potato for an equally delicious variation.
- Mini Crème Brûlées: Bake in small espresso cups for bite-sized servings at parties.
Tips & Troubleshooting
- If your custard splits, use the fine mesh sieve to try to rescue the texture, or turn the batch into a delicious dessert sauce for cakes.
- Overbaked custards will be rubbery; watch for the telltale jiggle in the center before removing from oven.
- Adding a little citrus zest (from orange or lemon) to the custard base can brighten the sweet potato’s earthy flavor.
Why Sweet Potato?
Sweet potatoes deliver earthy, gently sweet notes and a subtle orange color that bring autumn to mind. Their natural starches give the custard extra body, making this the perfect dessert for cozy dinners or holiday tables. Pair with coffee or dessert wine for an unforgettable finale.
