I developed this recipe after years of testing sweet potato preparations, and it never fails to impress, whether served as a side or a dessert-like centerpiece.

Ingredients for sweet potato recipe cinnamon brown sugar butter
Five ingredients, one baking sheet—this sweet potato roast transforms humble spuds into restaurant-worthy comfort food.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Medium, peeled and cubed evenly |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for even coating |
| Packed Brown Sugar 🍯 | ½ cup | Light or dark variety preferred |
| Ground Cinnamon 🌿 | 2 tbsp | Freshly ground for best flavor |
| Kosher Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For tossing and crispy edges |
Sweet potatoes are the star, so pick firm, vibrant orange ones—the deeper the color, the sweeter the flavor. I always grab organic sweet potatoes from Trader Joe's when I can, but any good-quality sweet potato works. Cut them into 1-inch cubes for even cooking, and don't skip peeling—they caramelize better without the skin. The key to those crispy edges? Even-sized cubes and a hot oven. If you're using pre-cut sweet potatoes, pat them dry first—they'll crisp up better.
No brown sugar? White sugar plus extra cinnamon works in a pinch, but brown sugar's molasses gives that deep caramel flavor. Butter is non-negotiable here—it's what creates those golden, crispy edges. European-style butter like Plugrá melts beautifully, but any good-quality butter will do. Short on time? Toss the cubes in olive oil first, then add the butter mixture—they'll still taste amazing. Fresh cinnamon sticks can be lightly toasted and ground for a deeper flavor, but the ground version is fine too. Just make sure it's freshly ground—old cinnamon tastes dull.
This roast tastes even better the next day—honestly, I often make a double batch. Store leftovers in an airtight container for up to 5 days. The cubes stay tender but crisp up again when reheated. For extra crispy edges, broil for 2-3 minutes before serving. Freezes beautifully too—portion into single servings before freezing for 3 months. The butter mixture can be prepped ahead and stored in the fridge for 1 week, saving you time on cooking day.

Step-by-step instructions for sweet potato cinnamon brown sugar butter roast
Here's how to transform simple sweet potatoes into caramelized, spiced perfection.
🔥 Step 1: Prep the Sweet Potatoes for Maximum Flavor
Preheat your oven to 425°F—this high heat is crucial for those caramelized edges. While it heats, toss the 2 lbs sweet potatoes (cubed evenly) in a large bowl with 1 tablespoon extra-virgin olive oil. Toss vigorously until every piece is lightly coated—this oil will create a crispy exterior while keeping the insides tender.
Here's the thing—don't skip the even cubing. I like 1.5-inch cubes because they cook through perfectly while developing that gorgeous caramelized crust. If you see any larger chunks, cut them further. The goal is uniform cooking so every bite delivers both crispy edges and creamy centers.
👨🍳 Step 2: Create the Spiced Butter Coating
In a separate bowl, combine the ½ cup cold cubed butter, ½ cup packed brown sugar, 2 tablespoons ground cinnamon, and 1 teaspoon kosher salt. Use your hands (they're the best tool for this) to work the butter until it's fully incorporated with the spices and sugar. You're looking for a crumbly, pea-sized mixture that coats your fingers.
This is where the magic happens—the butter will melt and caramelize during roasting, creating that signature sticky-sweet glaze. I press the mixture gently into the sweet potatoes, making sure each piece gets coated on all sides. Don't worry if it looks messy—this is supposed to be a generous coating. The potatoes will absorb just enough to develop flavor without becoming soggy.
🔥 Step 3: Roast Until Caramelized and Tender
Spread the coated sweet potatoes in a single layer on two rimmed baking sheets—don't overcrowd, or they'll steam instead of crisp. Roast for 25 minutes, then carefully flip each piece using tongs. This is the moment that matters: you want the butter to melt and caramelize on both sides, creating that beautiful mahogany crust.
After another 20-25 minutes, check for doneness. The edges should be deep golden brown with caramelized butter pooling on top, and a knife should slide in easily with just slight resistance. If they're not quite there, return to the oven for 5-10 more minutes. The internal temperature should reach 200°F—this ensures they're tender all the way through without being mushy.
🍽️ Step 4: Rest and Serve Warm
Transfer the roasted sweet potatoes to a serving platter and let them rest for 5 minutes. This resting period allows the juices to redistribute, ensuring each bite is moist and flavorful. The caramelized butter will continue to set slightly, creating that perfect balance of crispy edges and creamy interior.
Serve immediately while still warm—these are best enjoyed straight from the oven. The combination of crispy edges, tender sweet potato, and that sticky-sweet cinnamon butter glaze makes this dish irresistible. For extra presentation, drizzle any remaining caramelized butter from the baking sheet over the top before serving.
Pro Tips For Making Sweet Potato Recipe Cinnamon Brown Sugar Butter
- USE A KNIFE, NOT A PEELER: Cut the sweet potatoes lengthwise into ½-inch thick slices instead of peeling them first—this keeps the edges intact and prevents them from falling apart when you flip them. I learned this the hard way after watching my first batch disintegrate into a mushy pile.
- MELT THE BUTTER FIRST: Brown the butter before adding the sweet potatoes—it deepens the flavor and gives that caramelized richness you’d pay extra for at a café. Just don’t walk away; keep an eye on it or it’ll turn into bitter bits faster than you can say “burnt butter.”
- SALT THE POTATOES BEFORE BAKING: Season the sweet potatoes with a pinch of kosher salt before they hit the oven—it draws out moisture and helps the cinnamon-sugar crust stick. Skipping this step means your dish tastes flat, like someone forgot to season it at the last minute.
- COVER THEM HALFWAY: Tent the pan with foil after the first 15 minutes—this traps steam and softens the potatoes evenly without steaming them into mush. Remove the foil for the last 10 minutes to let the edges crisp up properly. (Yes, even if you’re impatient like me.)
Perfect pairings for this dish
Creamy Pairings
This roast pairs beautifully with vanilla ice cream for a dessert-like experience. The warm, spiced sweet potatoes contrast perfectly with the cool creaminess of ice cream. I like to serve it with a scoop of homemade vanilla bean ice cream or a high-quality store brand like Breyers. 🍦
For a savory option, try mashed potatoes with a touch of sour cream and chives. The creamy texture balances the caramelized edges of the sweet potatoes.
I often make a double batch of mashed potatoes and mix in a spoonful of the leftover cinnamon butter from the roasting pan—it’s a game-changer!
Protein Complements
Pair these sweet potatoes with herb-roasted chicken thighs for a cozy dinner. The crispy skin on the chicken contrasts nicely with the tender sweet potatoes. I season the chicken with rosemary, garlic, and paprika before roasting it alongside the sweet potatoes—both dishes finish cooking at the same time. 🍗
For a vegetarian option, try crispy tofu tossed in a soy-ginger glaze. The umami flavors complement the sweet-spiced potatoes beautifully. I press extra-firm tofu, cube it, and pan-fry it until golden before drizzling with a mix of soy sauce, grated ginger, and a touch of honey.
Serve together for a balanced plate.
Beverage Pairings
A spiced chai latte is the perfect drink to accompany this dish. The warm spices in the chai—like cinnamon, cardamom, and ginger—echo the flavors in the sweet potatoes.
I love using Starbucks Chai Latte mix for convenience, or making my own with black tea, milk, and a blend of spices. ☕
For something lighter, try a sparkling apple cider. The crisp acidity cuts through the richness of the butter and brown sugar. I chill a bottle of Martinelli’s Sparkling Cider and serve it over ice—it’s refreshing and pairs wonderfully with the warm, spiced sweet potatoes.
Extra Garnishes
Before serving, sprinkle the roasted sweet potatoes with toasted pecans for added crunch. I toast ½ cup pecans in a dry skillet over medium heat for 3-4 minutes until fragrant, then chop them coarsely. The nutty flavor adds depth to the dish. 🌰
For a pop of brightness, add fresh mint leaves or cranberries. The mint adds a refreshing contrast, while the cranberries bring a tangy sweetness. I toss a handful of dried cranberries with a pinch of orange zest before sprinkling them on top—it’s a simple but effective touch.

Frequently asked questions
Can I use regular sugar instead of brown sugar?
Yes, but you'll lose that deep caramel flavor and molasses richness. For best results, use ½ cup white sugar plus 1 teaspoon extra molasses (or ½ teaspoon vanilla extract) to mimic brown sugar's complexity. The texture will be slightly less sticky, but the sweet-spiced flavor will still shine.
How do I make these extra crispy?
Pat the sweet potatoes completely dry with paper towels before tossing in oil, and spread them in a single layer on the baking sheet. Roast at 450°F (instead of 425°F) for the first 15 minutes, then reduce to 425°F. For final crispiness, broil for 2-3 minutes at the end.
What if my sweet potatoes turn out mushy?
Overcrowding or undercooking causes this. Always use even-sized cubes and spread them with space between pieces. Check doneness with a fork—it should pierce easily but with slight resistance. If they're still firm after 45 minutes, they need more time. For mushy potatoes, try mashing them with a little butter and cinnamon instead!
Can I make this ahead of time?
Roast the sweet potatoes 1 day ahead and store in an airtight container. Reheat in a 350°F oven for 10-15 minutes or until warmed through. The flavors actually improve overnight as the spices meld. For extra crispiness, broil for 2 minutes before serving.
What's the best way to serve this as dessert?
Top with vanilla ice cream** and a drizzle of caramel sauce, or serve with whipped cream and a sprinkle of toasted nuts. For a warm dessert, try spooning the roasted cubes into a bowl with a scoop of ice cream and a dollop of sour cream. The contrast of warm and cold makes it irresistible!
