What’s not to love about sweet potatoes transformed into a caramelized, maple-infused side dish?

What Ingredients are in Maple-Walnut Sweet Potatoes?
This recipe combines simple, wholesome ingredients to create a deliciously caramelized side dish with the perfect balance of sweet and savory flavors.
- 3 medium sweet potatoes (sliced 1/2 inch thick)
- 1/3 cup melted butter
- 1 1/2 teaspoons ground cinnamon
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/3 cup pure maple syrup (make sure it’s the real stuff, not pancake syrup)
- 1/3 cup chopped walnuts
- 1 teaspoon fresh thyme (optional, but adds a lovely herbaceous note)
For the best results, look for firm, unblemished sweet potatoes with smooth skin, and consider toasting your walnuts beforehand to enhance their nutty flavor profile—just a minute or two in a dry skillet can make all the difference.
How to Make these Maple-Walnut Sweet Potatoes
Step 1: Preheat Your Oven
Turn your oven to 400°F (200°C) and give it enough time to fully heat up while you prep the ingredients. A properly preheated oven makes all the difference in getting that perfect caramelization. When preparing this recipe, having a high-quality baking set can make the cooking process smoother and more enjoyable.
Step 2: Prepare the Sweet Potatoes
Slice 3 medium sweet potatoes into approximately 1/2-inch thick pieces. The uniform thickness helps them cook evenly—too thin and they’ll burn, too thick and you’ll be waiting all night for them to soften.
Step 3: Season the Sweet Potatoes
In a large bowl, toss your sliced sweet potatoes with 1/3 cup melted butter, 1 teaspoon of the ground cinnamon (saving the rest for later), 1/2 teaspoon salt, and 1/2 teaspoon black pepper. Make sure each slice gets a nice coating of this flavorful mixture.
Step 4: Arrange and Bake
Spread the seasoned sweet potato slices in a single layer on a baking sheet—crowding leads to steaming rather than roasting, and nobody wants soggy potatoes. Bake for about 30 minutes, or until the potatoes are tender when pierced with a fork.
Step 5: Prepare the Maple-Walnut Mixture
While the potatoes are roasting, mix together 1/3 cup pure maple syrup, 1/3 cup chopped walnuts, 1 teaspoon fresh thyme if you’re using it, and the remaining 1/2 teaspoon of cinnamon. This mixture will create that irresistible sweet-nutty glaze that makes this dish so special.
Step 6: Add the Maple Glaze
Once the potatoes are tender, pour the maple-walnut mixture evenly over them, making sure to coat as many pieces as possible. Return the baking sheet to the oven for an additional 10 minutes, which allows the syrup to bubble and the walnuts to toast.
Step 7: Rest Before Serving
Remove from the oven and let the sweet potatoes rest for about 5 minutes. This brief waiting period allows the maple glaze to set slightly and the flavors to meld together. Plus, it gives you time to set the table or finish other dishes.
Step 8: Final Presentation
Transfer to a serving dish, making sure to scrape all that delicious maple glaze from the baking sheet. For an extra touch, you might sprinkle with a few more fresh thyme leaves or even a light dusting of cinnamon before bringing it to the table.
What to Serve with Maple-Walnut Sweet Potatoes
These sweet and nutty potatoes make a perfect dinner side dish, especially alongside roasted pork tenderloin or a simple grilled chicken breast. For a complete fall or holiday meal, pair them with green beans almondine or a crisp arugula salad with light vinaigrette—the peppery greens balance the sweetness beautifully.
Looking for a drink pairing? A glass of apple cider (hot or cold) complements the maple flavor wonderfully, or try an oaked chardonnay if you’re serving wine.
These potatoes also shine alongside savory herb-roasted turkey at Thanksgiving, where the maple syrup creates a delightful contrast to traditional gravy. For a finishing touch, a dollop of tangy Greek yogurt on top cuts through the richness and adds creamy contrast.
Maple-Walnut Sweet Potatoes Substitutions and Variations
- Nut options: Pecans work beautifully instead of walnuts, or try a mix of both for texture variety. For nut allergies, pepitas (pumpkin seeds) make a crunchy alternative.
- Dairy-free/vegan: Substitute coconut oil or olive oil for butter. The coconut adds a subtle tropical note that plays nicely with the sweet potatoes.
- Sweetener swaps: Honey or brown sugar can replace maple syrup in a pinch. For a lower-sugar version, use half the maple syrup and add a splash of orange juice.
- Spice it up: Add warming spices like nutmeg, cardamom, or a pinch of cayenne for a sweet-heat combination.
- Make it a meal: Turn this into a main dish by adding black beans and crumbled goat cheese on top.
- Seasonal garnishes: Fresh pomegranate seeds add beautiful color and tartness during holiday months, while a sprinkle of crumbled bacon takes this dish to indulgent territory.
Leftovers and Storage for these Maple-Walnut Sweet Potatoes
These sweet potatoes store beautifully in an airtight container in the refrigerator for up to 4 days. The flavors actually deepen overnight, making them possibly even more delicious the next day!
To reheat, pop them in a 350°F oven for 10-15 minutes until warmed through. This method helps maintain that delightful contrast between the crisp edges and tender centers. Microwaving works in a pinch (1-2 minutes), but you’ll lose some of that wonderful texture.
For freezing, store in freezer-safe containers for up to 2 months. The nuts might lose some crunch after freezing, so consider adding fresh walnuts when reheating frozen portions.
To prevent sogginess, reheat uncovered to allow steam to escape. A quick drizzle of fresh maple syrup just before serving refreshes the flavor beautifully.
Final Thoughts
This Maple-Walnut Sweet Potato recipe captures the essence of comfort food with its harmonious blend of earthy sweet potatoes, warm cinnamon, and the rich sweetness of pure maple syrup.
The walnuts add a wonderful textural contrast and nutty flavor that elevates this beyond an ordinary side dish. It’s particularly wonderful during autumn gatherings and holiday meals, when the warming spices and seasonal ingredients feel most appropriate.
The dish requires minimal hands-on time but delivers maximum flavor, making it perfect for both special occasions and Sunday family dinners. As the aroma of cinnamon and maple fills your kitchen, you’ll understand why some recipes become treasured traditions that return to our tables year after year.
Frequently Asked Questions
Can I Prepare These Sweet Potatoes a Day Ahead?
Yes, you can! I’d recommend preparing through step 3, refrigerating overnight, then reheating at 350°F for 15 minutes before adding the maple-walnut mixture and finishing the recipe as directed.
Are These Sweet Potatoes Suitable for a Diabetic Diet?
I’d be cautious about serving these to someone with diabetes. The maple syrup adds significant sugar content. You could modify the recipe by reducing or replacing the syrup with a diabetic-friendly alternative.
How Do I Prevent the Walnuts From Burning?
I’d add the walnuts only during the final 10-minute bake after the potatoes are tender. If they’re still burning, try covering the dish with foil for the last few minutes of cooking.
Can I Use a Slow Cooker Instead of the Oven?
I wouldn’t recommend a slow cooker for this recipe. You need the dry heat of an oven to caramelize the potatoes and create that desirable roasted texture. Slow cooking would make them too soggy.
What’s the Best Way to Reheat Without Making Them Soggy?
I’d recommend reheating in a 350°F oven for 10-15 minutes – it’ll maintain the texture better than a microwave. If you’re in a hurry, use a toaster oven or air fryer for crispier results.
