How to Make Walnut Maple Roasted Sweet Potatoes
Step 1: Prepare the Sweet Potatoes
Start by washing your sweet potatoes and slicing them into half-inch thick rounds. You can leave the skin on for a lovely texture and extra nutrients or peel them if you prefer a smoother bite. Then, preheat your oven to 200°C (400°F) to ensure it’s hot and ready for roasting.
Step 2: Season the Sweet Potatoes
In a large mixing bowl, toss the sweet potato slices with melted butter, one teaspoon of cinnamon, salt, and pepper. Make sure each slice is generously coated — this step locks in the flavor and helps the edges crisp up beautifully. If you want, you can mix everything inside a ziplock bag and shake it for an easy and mess-free method.
Step 3: Arrange for Roasting
Place the seasoned sweet potato slices on a baking tray in a single layer, leaving some space between each piece. This spacing is crucial for even roasting and browning instead of steaming. Pop the tray in your preheated oven and roast for about 25 to 30 minutes, or until the potatoes are tender when pierced with a fork and the edges start to caramelize.
Step 4: Prepare the Topping
While your sweet potatoes are roasting, mix together the maple syrup, chopped walnuts, the remaining half teaspoon of cinnamon, and thyme in a small bowl. This lovely mixture will create a glossy, crunchy caramelized topping that perfectly complements the soft potatoes.
Step 5: Add the Topping and Finish Roasting
Once your sweet potatoes are tender, carefully remove the baking tray from the oven. Spoon about a teaspoon of the walnut and maple mixture over each slice. Return the tray to the oven for an extra 8 to 10 minutes or until the topping is beautifully caramelized and the edges have turned a golden brown.
Step 6: Serve and Enjoy
Let your Walnut Maple Roasted Sweet Potatoes cool just slightly before serving. They’re amazing on their own, but if you want to add a creamy, tangy note, sprinkle some crumbled feta cheese on top. This dish is a magical blend of textures and flavors that your taste buds will thank you for.
How to Serve Walnut Maple Roasted Sweet Potatoes

Garnishes
Enhance your Walnut Maple Roasted Sweet Potatoes by garnishing with fresh thyme sprigs or a little sea salt flakes to add a finishing touch. For a pop of color and a bit of tangy contrast, crumbled feta or goat cheese works wonders, balancing the sweetness with a creamy bite.
Side Dishes
This dish pairs incredibly well with roasted meats like chicken or pork, and it adds a sweet balance to savory mains. You can also serve it alongside a crisp green salad or a bowl of sautéed greens, making it a well-rounded and colorful plate.
Creative Ways to Present
For a beautiful and festive presentation, arrange the Walnut Maple Roasted Sweet Potatoes on a wooden serving board garnished with extra chopped walnuts and fresh thyme. You can also drizzle a little extra maple syrup over the top just before serving to give it that shiny, mouthwatering glaze.
Make Ahead and Storage
Storing Leftovers
Place any leftover Walnut Maple Roasted Sweet Potatoes in an airtight container and store them in the refrigerator. They will stay fresh for up to 4 days, making this recipe a great make-ahead side to enjoy through the week.
Freezing
You can freeze roasted sweet potatoes, but the walnut maple topping might lose some texture upon thawing. For best results, freeze the roasted sweet potatoes separately without the topping, and prepare the walnut maple mixture fresh before serving.
Reheating
Reheat your Walnut Maple Roasted Sweet Potatoes gently in the oven at 175°C (350°F) for about 10-15 minutes. This will help maintain the crispy edges and keep the topping delightfully caramelized. Avoid microwaving if you want to preserve texture.
