- 2 pounds sweet potatoes: Peeled and diced into 1-inch cubes, they provide the vibrant base packed with natural sweetness and creaminess.
- 3 tablespoons olive oil: Ideal for roasting, it helps the sweet potatoes crisp up beautifully while keeping them moist.
- 1/4 cup maple syrup: Adds a rich, natural sweetness that caramelizes perfectly in the oven.
- 1 teaspoon cinnamon: Brings warmth and depth, enhancing the sweetness without overpowering it.
- Salt and pepper: Essential for balancing flavors and adding a little savory edge to this otherwise sweet dish.

How to Make Walnut Maple Roasted Sweet Potatoes Recipe
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). A hot oven is key to getting that beautiful caramelization on the sweet potatoes and toasting the walnuts just right.
Step 2: Toss Sweet Potatoes with Flavors
In a large bowl, combine your diced sweet potatoes with olive oil, maple syrup, cinnamon, salt, and pepper. Toss everything together so every cube is evenly coated, ensuring maximum flavor with every bite.
Step 3: Arrange on Baking Sheet
Spread the sweet potatoes out in a single layer on a parchment-lined baking sheet. Giving them space helps them roast evenly and get that wonderful crispy edge.
Step 4: Roast for 20 Minutes
Pop the baking sheet into your preheated oven and roast for 20 minutes. This initial roasting softens the potatoes and starts the caramelization process.
Step 5: Add Walnuts and Toss
Remove the sweet potatoes from the oven and sprinkle the chopped walnuts evenly over the top. Gently toss to combine so those walnuts start to infuse their flavor throughout the dish.
Step 6: Continue Roasting Until Perfect
Return the pan to the oven and roast for another 10 to 15 minutes. You’re looking for tender, caramelized sweet potatoes and perfectly toasted walnuts — a balance of soft and crunchy.
Step 7: Let Cool Slightly
Once out of the oven, allow the dish to cool just a bit. This brief rest lets the flavors meld together, making every bite more harmonious and delicious.
Step 8: Garnish and Serve
Finish with a sprinkle of fresh parsley or thyme if you like, adding a fresh, herbal note plus a pop of color to your Walnut Maple Roasted Sweet Potatoes Recipe, ready to serve warm.

Make Ahead and Storage
Storing Leftovers

FAQs
Can I use a different type of nut?
Absolutely! Pecans or hazelnuts make delightful substitutes, adding their own unique crunch and flavor. Just chop and toast them the same way as walnuts to keep that toasty, nutty goodness.

Definitely! Since none of the ingredients contain gluten, this dish is naturally gluten-free and safe for those with gluten sensitivities or celiac disease.
What if I don’t have fresh herbs for garnish?
No worries at all! The dish will still shine without herbs, but you can try dried herbs sprinkled on top after roasting or even a light drizzle of extra maple syrup for added sweetness.
How do I make the sweet potatoes less sweet if preferred?
Reduce the maple syrup slightly or omit it, then compensate with a bit more olive oil and seasoning. A touch of lemon juice after roasting can also cut through the sweetness for a balanced finish.
