intro

Silky, warmly spiced roasted sweet potato ice cream is a cozy twist on classic fall flavors, ideal for serving alongside holiday pies or as a standalone cold treat.

Ingredients

Orange-fleshed sweet potato 250g (1 medium, scrubbed)
Heavy whipping cream 360ml (1.5 cups)
Whole milk 120ml (0.5 cup)
Granulated sugar 100g (0.5 cup)
Large egg yolks 3 (60g total)
Ground cinnamon 1 teaspoon
Freshly grated nutmeg 1/4 teaspoon
Pure vanilla extract 1 teaspoon
Fine sea salt 1/8 teaspoon

Steps

1

Roast the sweet potato

Preheat oven to 200°C (400°F). Prick the scrubbed 250g sweet potato 5-6 times with a fork, place directly on the middle oven rack, and roast for 40-45 minutes until flesh is completely tender when pierced with a paring knife. Remove from oven and let cool for 15 minutes at room temperature until safe to handle.

2

Make sweet potato puree

Slice the cooled roasted sweet potato in half lengthwise, scoop out all soft flesh (discard the tough skin) into a high-speed blender or food processor. Blend on high for 30-45 seconds until completely smooth with no remaining lumps. Measure out exactly 200g (about 3/4 cup) of the puree, set aside, and reserve any excess puree for other uses.

Cook custard base

In a small heavy-bottomed saucepan over medium-low heat, combine the 120ml whole milk, 50g (1/4 cup) of the granulated sugar, 1 teaspoon cinnamon, 1/4 teaspoon nutmeg, and 1/8 teaspoon fine sea salt. Stir constantly for 3-4 minutes until the mixture reaches 70°C (160°F) and sugar is fully dissolved; do not bring to a boil. In a separate heatproof glass bowl, whisk the 3 egg yolks with the remaining 50g (1/4 cup) sugar until pale lemon yellow, about 1 minute. Slowly pour 1/3 of the warm milk mixture into the egg yolks while whisking nonstop to temper the eggs and prevent curdling, then pour the tempered egg mixture back into the saucepan. Cook over low heat, stirring constantly with a silicone spatula, for 4-5 minutes until the custard thickens enough to coat the back of the spatula (reaches 82°C/180°F); do not boil.

Chill the ice cream base

Remove the thickened custard from heat immediately, stir in the measured 200g sweet potato puree, 360ml heavy cream, and 1 teaspoon vanilla extract until fully combined and a uniform warm orange color. Pour the base through a fine-mesh sieve into a shallow airtight glass container to remove any lumps or tiny curdled egg bits. Press a piece of plastic wrap directly onto the surface of the base to prevent a skin from forming, then refrigerate for a minimum of 4 hours (or up to 24 hours for deeper flavor) until completely chilled to 4°C (40°F) or colder.

Step 4
step4:Chill the ice cream base
5

Churn the ice cream

Remove the fully chilled base from the refrigerator, peel off the plastic wrap, and pour the base into a pre-frozen ice cream maker canister. Churn according to the manufacturer’s instructions, typically 20-25 minutes, until the ice cream reaches a thick, billowy soft-serve consistency that holds its shape when lifted with a spoon.

Step 5
step5:Churn the ice cream
6

Harden the ice cream

Transfer the churned soft ice cream into a 1L freezer-safe airtight container, smoothing the top evenly with a spatula. Seal the lid tightly, and freeze for 2 hours until the ice cream is firm enough to scoop into clean rounds but still retains a creamy, smooth texture. If freezing for longer than 4 hours, let the container sit at room temperature for 5-10 minutes before scooping to soften slightly for easier serving.

Step 6
step6:Harden the ice cream

Tips

1.For a quick no-churn version, skip the egg custard step: fold 200g smooth sweet potato puree and spices into 360ml heavy cream whipped to stiff peaks, mixed with 100g sweetened condensed milk, then freeze for 6 hours without churning.
2.Never boil sweet potato instead of roasting it: boiling adds excess water that makes finished ice cream icy and grainy, while roasting caramelizes the sweet potato’s natural sugars for a deeper, richer flavor.
3.For a festive Thanksgiving serving, top scoops with 1 tablespoon of toasted chopped pecans, a 1 teaspoon drizzle of maple syrup, or a light sprinkle of cinnamon sugar to complement the warm spiced flavor.

Sweet Potato Ice Cream:Frequently Asked Questions

1.Can I boil my sweet potatoes instead of roasting them to cut down on prep time for this ice cream?
Roasting is strongly preferred here—it caramelizes the sweet potato’s natural sugars, amplifies its warm, earthy flavor, and cooks off excess moisture that would leave your ice cream icy instead of silky. If you’re in a pinch, steam cubed sweet potato instead of boiling, and press it through a fine-mesh sieve to remove extra water before mixing it into your custard base.

OMG this creamy roasted sweet potato ice cream is such a game changer! I brought it to my neighborhood potluck last weekend and everyone was begging for the recipe. I added a tiny pinch of extra cinnamon on top and it was chef’s kiss. Only thing is I was worried my ice cream maker was too small at first, but it worked out!

2 days ago

Wait how much extra cinnamon did you add? I’m obsessed with warm spice flavors and don’t want to overdo it!

1 day ago

So happy it was a potluck hit! A 1/4 tsp extra of ground cinnamon per batch works perfectly if you love that warm spice kick without overpowering the sweet potato flavor.

My kids were so skeptical when I said we were making sweet potato ice cream for our Sunday family dinner dessert, but they devoured every single scoop! The roasted sweet potato flavor comes through so nicely without being weirdly veggie-tasting. The cook time is long for sure, but most of it is just waiting for it to chill so it’s not that bad.

5 days ago

Same here! My 7 year old turned his nose up until he tried a bite, now he asks for it every time we do taco night lmao

Love hearing the kid-approved feedback! The long inactive chill time is totally worth it for that ultra creamy, no ice crystal texture, right?

3 days ago

Wait, has anyone tried making this dairy free? I’m thinking of swapping the heavy cream for full fat coconut cream but I’m worried it’ll mess with the texture. Roasted sweet potato in ice cream sounds too good to pass up for my monthly meal prep dessert rotation!

2 days ago

I did that exact swap last week! It turned out amazing, just make sure you chill the coconut cream overnight first so it’s extra thick. I also added a tablespoon of maple syrup to bump up the sweetness a little.

1 day ago

Great question! The full fat coconut cream swap works beautifully, just note that it will have a very subtle coconut undertone that pairs really nicely with the roasted sweet potato and warm spices.

I made this for our Thanksgiving pre-game dinner last week and it was SO good! I paired it with a pecan crumble topping and it tasted just like sweet potato casserole but in ice cream form. My only tiny complaint is I wish the recipe noted how long to roast the sweet potatoes for? I think I underdid mine a little because the flavor wasn’t as deep as I wanted.

1 week ago

I roasted mine at 400F for 45 minutes until they were super soft and caramelized on the edges, that gave the best deep flavor! Pro tip: don’t skip lining the baking sheet with parchment, the sugary bits leak a little.

1 week ago

Thanks so much for the feedback! We’ve updated the recipe card to note that sweet potatoes should roast for 40-45 minutes at 400°F until fork tender and slightly caramelized for the deepest, richest flavor. So glad you enjoyed the pecan crumble pairing, that sounds incredible!

Just pulled my first batch out of the ice cream maker and it’s so creamy I could cry! I was worried medium difficulty meant I’d mess it up, but the instructions are super straightforward. I added a little bourbon swirl to half the batch for my partner and it’s insane. 10/10 will make again.

30 minutes ago

Oh the bourbon swirl idea is genius! How much bourbon did you use for the swirl? I want to do that for my friend’s housewarming this weekend.

5 minutes ago

So glad the easy to follow instructions made it less intimidating! The bourbon swirl sounds like such a fun, grown up twist — we might have to test that version ourselves!

Whoa, sweet potato ice cream? I was fully expecting this to be a weird health food gimmick but it’s actually decadent as hell. The creamy texture is way better than store bought ice cream I’ve paid $8 a pint for. Worth every minute of wait time.

We love when people are skeptical and end up obsessed! The roasting step really brings out the natural sweetness of the sweet potatoes so you don’t need tons of extra sugar to make it taste rich and indulgent.

This is such a perfect gluten free dessert option for my kid’s birthday party! I was struggling to find something that wasn’t just chocolate or vanilla that all the kids would eat, and this was a total hit. I served it in little waffle cones (gluten free, obviously) and no one even guessed there was sweet potato in it.

5 days ago

Oh that’s such a good idea! My youngest has celiac so I’m always hunting for fun GF desserts that don’t feel like a compromise, can’t wait to try this for his next class party.

I messed up the first batch because I forgot to let the custard cool all the way before churning, oops. Ended up with a weird soupy mess, but I tried again yesterday and followed the steps exactly and it came out perfect. Don’t rush the chill time, folks!

We’ve all been there! Rushing the custard chill step is the #1 mistake people make with homemade ice cream, so glad you gave it a second shot and it worked out for you!

Y’all, I served this alongside my famous pecan pie at our family cookout and people were going back for seconds of the ice cream more than the pie! I added a sprinkle of toasted marshmallow bits on top for that sweet potato casserole vibe and it was chef’s kiss.

1 week ago

Wait toasted marshmallow bits?! That’s the upgrade I didn’t know I needed. I’m making this for my boyfriend’s family dinner next week and I’m definitely stealing that idea.

yesterday

I love that this stays creamy in the freezer for a whole week! Most homemade ice cream gets rock solid and impossible to scoop after a couple days, but this scoops perfectly straight out of the freezer. It’s my new go-to Sunday meal prep dessert for busy weeknights.

2 hours ago

That’s all thanks to the natural starch from the roasted sweet potatoes! It helps keep ice crystal formation super low so it stays silky and scoopable for days, no fancy additives needed.

30 minutes ago

Wait, is it possible to make this without an ice cream maker? I’m in a dorm and don’t have space for one, but this looks so good I’d try the no-churn method if anyone has tips.

5 minutes ago

I did the no-churn method last month! Just fold the cooled roasted sweet potato puree and spices into whipped heavy cream and sweetened condensed milk, then freeze for 6 hours. It’s not quite as creamy as the churned version but it’s still really tasty!

2 days ago

I thought the medium difficulty rating was overblown until I realized I had to make a custard base, lmao. I’ve never made a custard before so I was paranoid about scrambling the eggs, but I took it slow and it turned out perfectly. Don’t let the medium tag scare you if you’re a beginner!

1 day ago

So proud of you nailing the custard on your first try! We marked it medium mostly because of the custard step and long chill time, but as long as you heat the base slowly and stir constantly, it’s totally doable for new bakers.

I added a pinch of cayenne pepper to my batch and it was insane! The little hint of heat pairs so well with the sweet, creamy sweet potato and cinnamon. It tastes like fall in a scoop, I’m obsessed.

5 days ago

Cayenne in sweet ice cream is such an underrated combo! I do that with my chocolate ice cream all the time, can’t wait to try it with this sweet potato version.

just now

Okay I’ll be real, I saw 7 and a half hours total time and almost clicked away, but my roommate begged me to make it with her. Turns out 6.5 hours of that is just waiting for it to chill and freeze, the actual work is super easy. 10/10 would make again, even for my lazy self.

I’ve been making sweet potato pie for 50 years and never thought to turn it into ice cream! This tastes just like my famous pie filling but cold and creamy. My grandkids went crazy for it when they visited last weekend. What a fun, creative recipe.

5 days ago

I made this for a post-hike hangout with my friends last weekend and everyone was raving. It’s sweet but not too heavy, so it didn’t make us feel sluggish after being out on the trail all morning. I’ll definitely be adding this to my regular adventure snack rotation.

yesterday

Okay so I definitely over-roasted my sweet potatoes a little so they had a tiny burnt edge, but I just cut those parts off and it still turned out amazing! Even my mistakes couldn’t ruin this recipe, that’s how good it is. Will definitely be more careful with the roast time next batch though.

Made this for my anniversary dinner with my girlfriend last night and she thought I ordered it from a fancy artisanal ice cream shop! Little does she know it was way easier to make than it sounds, I’ll be taking full credit for being a master chef for the next month lmao.

I swapped the regular brown sugar for maple sugar in my batch and it gave it the coziest, woodsy fall flavor that pairs so perfectly with the roasted sweet potato. I topped each scoop with a candied pecan and it was literally the best dessert I’ve made all fall. SO good!
