How to Make Walnut Maple Roasted Sweet Potatoes Recipe
Step 1: Prep Your Sweet Potatoes
Start by slicing your sweet potatoes into half-inch rounds. You can keep the skin on for extra texture and nutrients or peel them if you prefer a smoother bite. This step sets the foundation for even roasting and helps the flavors meld beautifully.
Step 2: Heat Things Up
Preheat your oven to 200°C (or 400°F). A hot oven ensures the sweet potatoes get a lovely caramelized exterior while becoming tender inside, which is key to this recipe’s success.
Step 3: Coat with Butter and Spices
In a large bowl, mix those sweet potato slices with melted unsalted butter, cinnamon, salt, and pepper. Every slice deserves this flavorful coating — it’s what transforms plain potatoes into something truly special.
Step 4: Roast Until Tender
Spread the slices evenly on a baking tray, making sure they don’t overlap, and roast for 25-30 minutes. You’ll know they’re ready when they’re soft to the touch and the edges begin to brown beautifully.
Step 5: Prepare the Walnut Maple Glaze
While the potatoes are roasting, mix maple syrup with chopped walnuts, cinnamon, and thyme. This glaze is the magic touch that adds depth and a perfect crunch to the dish.
Step 6: Glaze and Caramelize
Remove the sweet potatoes from the oven, spoon the walnut maple glaze generously over each slice, and pop them back in for another 8-10 minutes. This step caramelizes the glaze and lets the nuts toast right on top, creating irresistible texture and flavor.
Step 7: Time to Enjoy!
Your Walnut Maple Roasted Sweet Potatoes Recipe is ready to serve as is, or you can add a little sprinkle of feta cheese for a tangy contrast. Whichever way you choose, this dish pairs perfectly with cozy autumn dinners or even a festive meal.
How to Serve Walnut Maple Roasted Sweet Potatoes Recipe

Garnishes
To brighten the final presentation, fresh herbs like parsley or a few extra thyme sprigs work wonderfully. A light sprinkle of feta cheese or crumbled goat cheese adds creamy, tangy notes that complement the sweetness perfectly.
Side Dishes
This recipe shines next to roast chicken, pork tenderloin, or even grilled salmon. It also pairs well with simple green salads or steamed veggies to round out your plate with freshness and balance.
Creative Ways to Present
For a festive touch, serve the roasted sweet potatoes in a rustic wooden bowl or on a large platter with the walnuts scattered on top. Drizzle any extra maple glaze over the plate and add color with pomegranate seeds or dried cranberries for an eye-catching twist.
Make Ahead and Storage
Storing Leftovers
Place any leftover Walnut Maple Roasted Sweet Potatoes in an airtight container and refrigerate for up to 4 days. The flavors actually deepen overnight, making for a delicious next-day treat.
Freezing
If you want to keep them longer, freeze the cooked sweet potatoes in a single layer on a baking sheet first, then transfer to freezer bags or containers. They’ll last up to 3 months but are best enjoyed within the first month for optimal texture.
Reheating
Reheat your leftovers in a preheated oven at 180°C (350°F) to retain crispness, or gently warm in a skillet. Avoid microwaving if you want to keep the walnuts crunchy and the sweet potatoes nicely caramelized.
FAQs
Can I use other nuts instead of walnuts?
Absolutely! Pecans or almonds make great substitutes and provide a similar crunch. Just chop them roughly and use the same quantity for that delightful toasted texture.
Is maple syrup necessary in this recipe?
Maple syrup is key to achieving the signature sweet caramelization and depth of flavor, but you could try honey as a substitute if needed. Keep in mind it will alter the flavor slightly.
Can this dish be made vegan?
Yes! Simply swap the unsalted butter for a plant-based alternative like coconut oil or vegan margarine, and make sure your maple syrup is pure and vegan-friendly.
Should I peel the sweet potatoes?
It’s completely up to your preference. Keeping the skin adds texture and nutrients, while peeling results in a smoother bite. Both ways yield delicious results.
How do I know when the sweet potatoes are fully cooked?
They’re done when a fork or skewer slides easily through the slices and the edges look nicely browned. If they’re still firm, just roast a little longer.
