Ingredients for sweet potato creme brulee tart
Eight ingredients transform into a showstopping dessert that tastes like autumn in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Orange flesh, peeled and cubed |
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cut into cubes |
| All-Purpose Flour 🌾 | 1 ½ cups | Plus 2 tbsp for pressing crust |
| Granulated Sugar 🍚 | ½ cup | Plus 1 cup for caramelized top |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Heavy Cream 🥛 | 2 cups | Full-fat for richness |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 💧 | 1 tbsp | Pure vanilla preferred |
| Light Brown Sugar 🍚 | ¼ cup | Packed, for crust |
| Turbinado Sugar 🍚 | 1 cup | Coarse, for caramelized top |
The sweet potatoes are the star—look for ones that are firm and vibrant orange (the deeper the color, the sweeter they'll be). Trader Joe's and Whole Foods always carry the best variety, but any grocery store will do. Roast them until caramelized for that natural sweetness boost—they should be tender enough to mash easily but still hold some texture. I like to use the Honey Bear brand sweet potatoes if I'm feeling fancy, but regular ones work perfectly fine. Don't skip the cinnamon and nutmeg—they're what give this tart that cozy, spiced depth that makes it feel like fall in dessert form.
No vanilla extract? Vanilla bean paste or even vanilla sugar will work in a pinch (just use half the amount of sugar). Running low on heavy cream? Full-fat coconut milk gives a similar richness, though the flavor will be slightly different. For the crust, if you don't have turbinado sugar, white sugar works too—just pack it tightly into the tart pan. The key to that perfect caramelized top is using coarse sugar—it creates those beautiful, crackly shards when torched. If you're nervous about torching, broiling for 2-3 minutes gives a similar effect (though not quite as dramatic).
This tart keeps beautifully—cover it and store in the fridge for up to 3 days, though it's best enjoyed within 24 hours when the caramelized top is at its peak. For make-ahead prep, you can assemble the tart (without torching) up to 1 day in advance and refrigerate. The crust can be baked separately and stored at room temperature for 3 days in an airtight container. When reheating, a quick broil for 2 minutes brings back that crispy edge on the crust—trust me, it's worth it!
Why You'll Love This Recipe
- Sweet Potato Magic: I swear, roasting the sweet potatoes first cuts the work in half—just toss them in the oven while you mix the dough. No peeling, no fuss, and they caramelize into something so rich, you’ll forget it was easy.
- Caramel Crunch Core: That crispy sugar top with the velvety sweet potato custard? It’s the kind of contrast that makes you close your eyes. The eggs and butter turn the filling into a dreamy, almost custardy texture that’s impossible to resist.
- Weeknight or Company: Honestly, this works for both. Serve it warm with ice cream for a casual night in, or slice it into fancy portions for guests. The tart crust holds up perfectly—no soggy bottoms here.
- Budget-Friendly Luxury: Sweet potatoes and eggs stretch further than you’d think, and the sugar topping doesn’t need to be fancy. It’s the kind of dessert that feels special without breaking the bank, and leftovers? They disappear just as fast as the first slice.
Step-by-step instructions for sweet potato crème brûlée tart
Here's how to create a showstopping tart with a crackling caramelized top and velvety spiced filling.
🍳 Step 1: Make the Sweet Potato Purée
Preheat your oven to 400°F. Toss the 2 lbs peeled and cubed sweet potatoes with 1 tablespoon olive oil (not listed but required for roasting) and spread them on a baking sheet. Roast for 25-30 minutes until fork-tender and caramelized at the edges.
Transfer the roasted sweet potatoes to a bowl and let them cool slightly. Then, using an immersion blender or food processor, purée until completely smooth. You should have about 3 cups of purée. Strain through a fine-mesh sieve to remove any skin bits for an ultra-silky texture. Set aside to cool completely before using.
👨🍳 Step 2: Prepare the Crust
In a large bowl, combine the 1.5 cups all-purpose flour and 0.5 tsp salt. Cut in the 1.5 cups cold, cubed unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces.
Add the 0.25 cup packed light brown sugar and mix until evenly distributed. Press this dough into a 9-inch tart pan (using about 2 tablespoons extra flour if needed to prevent sticking). Chill in the refrigerator for 30 minutes while you prepare the filling.
🍳 Step 3: Create the Silky Filling
In a medium saucepan, combine the 2 cups heavy cream, 0.5 cup granulated sugar, 1.5 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 1 tbsp vanilla extract. Heat over medium-low heat until steaming but not boiling, about 5 minutes.
In a separate bowl, whisk the 4 room-temperature eggs until just combined. Slowly pour the warm cream mixture into the eggs while whisking constantly. Then, gradually whisk in the 3 cups sweet potato purée until perfectly smooth. Pour this filling into the chilled tart shell.
𰰟 Step 5: Create the Caramelized Top
About 1 hour before serving, sprinkle the 1 cup turbinado sugar evenly over the chilled tart. Use a kitchen torch to carefully melt and caramelize the sugar until it forms a deep amber crust with crackling edges. Watch closely—the sugar burns easily!
If you don't have a torch, broil the tart for 2-3 minutes on high, keeping a close eye to prevent burning. Let the caramelized top cool slightly before slicing. Serve warm with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate indulgence.
Pro Tips For Making Sweet Potato Creme Brulee Tart
- ROAST THE SWEET POTATOES FIRST: Sweet potatoes straight from the bag taste bland and watery in this tart. Roast them whole at 400°F (200°C) for 45 minutes—pierce first, skin-on—until fork-tender. The concentrated sweetness and smooth texture make all the difference, and you’ll avoid that sad, grainy filling.
- CHILL THE CRUST BEFORE FILLING: I learned this the hard way—warm crusts collapse under custard. Press your flour-butter crust into the tart pan, then freeze it for 20 minutes before adding the sweet potato mixture. This keeps the structure intact while baking, so you don’t end up with a soggy bottom.
- WHISK EGGS COLD THEN TEMPER: Cold eggs thicken better and prevent curdling. Whisk them straight from the fridge with the sugar and roasted sweet potato purée, then slowly warm the mixture over a double boiler (or a heatproof bowl over simmering water) until it’s just about to coat the back of a spoon. Too hot, too fast, and you’ll scramble them.
- SALT THE SUGAR FOR CRUST: Skip the extra salt in the crust—mix 1 tsp fine salt into the 1 cup granulated sugar before cutting in the butter. The sugar dissolves faster and the crust gets a subtle, even saltiness without tasting like a salt lick. (Yes, even if you’re using unsalted butter.)
Make-ahead tips for sweet potato creme brulee tart
Crust Prep Ahead
Make the crust up to 3 days in advance and store it in an airtight container at room temperature. This gives the butter time to firm up, making it easier to press into the tart pan.
I like to chill the crust for an extra 15 minutes before baking to prevent shrinking. Just remove it from the fridge 10 minutes before baking to let it soften slightly—this helps it crisp up perfectly. 🧈
Filling Prep Timeline
Assemble the tart (without torching) 24 hours ahead and refrigerate. The filling will thicken slightly but still set beautifully when baked. To reheat, bake at 350°F for 15 minutes to restore the custard's silky texture.
I’ve even made the filling ahead and reheated it gently before pouring into the crust—just warm it to 100°F before combining with the eggs. This saves time on busy days! ⏰
Caramelized Top Shortcut
Skip the torch entirely by broiling the sugar-topped tart for 2-3 minutes on high. Watch closely—it should turn golden amber but not burn. For extra insurance, sprinkle the sugar 30 minutes before serving so it has time to settle.
I keep a small bowl of turbinado sugar pre-measured in my pantry so I’m never scrambling at the last minute. This method works just as well for parties where torching isn’t practical. 🔥
Freezing the Tart
This tart freezes beautifully for up to 2 months—just bake it completely (without torching), let it cool, then wrap tightly in plastic wrap followed by aluminum foil. To serve, thaw overnight in the fridge, then broil for 5 minutes to crisp the crust and reheat the filling.
The caramelized top can be added fresh after thawing for the best texture. I’ve even reheated frozen slices in the microwave for 20 seconds—they’re still delicious! ❄️
Make-Ahead Torching
For a foolproof caramelized top, torch the tart 30 minutes before serving and keep it refrigerated until ready to eat. The sugar will set as it cools, giving you that perfect crackly texture when sliced.
If you’re serving a crowd, torch multiple tarts and store them separately—this way, you can keep one warm while finishing others. Pro tip: Use a long-handled torch to avoid burning your hands on the hot sugar. ✨
Portioning for Guests
Slice the tart into wedges 1 hour before serving and arrange them on a platter. This makes it easy to torch individual portions right at the table—guests will love the interactive element!
For a buffet-style setup, cover the sliced tart with parchment paper and reheat each portion briefly under a broiler for 1 minute to restore crispness. I always bring extra sugar to refresh the caramelized top if needed. 🍽️

Frequently asked questions
Can I use regular white sugar instead of turbinado sugar for the caramelized top?
You can, but the texture will be different. Turbinado sugar creates those beautiful crackly shards when torched, while white sugar will make a smoother, less dramatic crust. If you're using white sugar, sprinkle it 30 minutes before torching to give it time to settle and caramelize properly. The flavor will be just as delicious, though!
How do I fix a watery custard in my tart?
If your custard is too thin, it's likely because the eggs weren't room temperature or the cream was too hot when mixed. For a quick fix, bake the tart at 325°F for 10-15 minutes longer than usual—this helps thicken the filling. You can also whisk in 1 tablespoon cornstarch mixed with 1 tablespoon cold water before pouring into the crust. Always strain the filling for extra silkiness!
What's the best way to store leftovers?
Store leftovers (without the caramelized top) in an airtight container in the fridge for up to 3 days. To refresh the caramelized top, sprinkle fresh turbinado sugar and torch just before serving. For longer storage, freeze the tart (without torching) for up to 2 months5 minutes to restore crispness.
Can I make this tart without a torch?
Broil the tart for 2-3 minutes on high heat, watching closely to avoid burning. Keep the oven door slightly open for better airflow. For even results, sprinkle the sugar 30 minutes before broiling so it has time to settle. This method works perfectly for parties where torching isn't practical.
How do I adjust the spice level for kids?
Reduce the cinnamon and nutmeg to 1 teaspoon each for a milder flavor. You can also add a pinch of vanilla bean paste for extra sweetness without extra spice. The natural sweetness of the roasted sweet potatoes will still shine through—just with a gentler kick. Perfect for little dessert lovers!
