Maple Cinnamon Roasted Sweet Potatoes (Caramelized, With Maple, Ready in 45 Minutes)

These maple cinnamon roasted sweet potatoes are the Thanksgiving side dish that disappears first. Thick slices roast until their edges caramelize, then a maple and cinnamon glaze turns glossy in the heat of the oven. They taste sweet, warm, and a little buttery, without needing marshmallows or a heavy topping. Best of all, they use one pan and a handful of pantry ingredients.

If you are building your Thanksgiving menu, pair these sweet potatoes with Sausage & Herb Bread Stuffing and Creamy Make-Ahead Mashed Potatoes for a table where every classic side is covered.

Why This Recipe Works

• Slices roast evenly: Cutting the sweet potatoes into even rounds means every piece caramelizes at the same rate, with no burnt thin bits or raw thick ones.
• Maple goes on early: Tossing the slices in maple before roasting lets the glaze reduce and cling, instead of sitting on top as a wet sauce.
• Cinnamon stays warm, not loud: One teaspoon is enough to make the dish taste like the holidays without turning it into dessert.
• One pan, easy cleanup: Everything roasts on a single lined sheet pan, so the side dish never competes with the turkey for oven space or attention.

Ingredients

• 2 1/2 lb (1.1 kg) sweet potatoes, peeled and sliced into 1/2-inch (1.3 cm) rounds
• 3 tablespoons (45 ml) olive oil
• 3 tablespoons (45 ml) pure maple syrup, plus extra for drizzling
• 1 teaspoon (2.6 g) ground cinnamon
• 1/2 teaspoon (3 g) fine salt
• 1/4 teaspoon (0.5 g) black pepper
• 1 tablespoon (3 g) chopped fresh thyme or rosemary (optional)
• 1/4 cup (30 g) chopped toasted pecans (optional, for serving)

How to Make Maple Cinnamon Roasted Sweet Potatoes

Step 1: Heat the oven and prep the pan

Heat the oven to 425°F (220°C). Line a large rimmed sheet pan with parchment paper. Peel the sweet potatoes and slice them into even 1/2-inch rounds so they cook at the same pace.

Step 2: Toss with maple and cinnamon

Whisk the olive oil, maple syrup, cinnamon, salt, and pepper in a large bowl. Add the sweet potato rounds and toss until every slice is coated. Spread them in a single layer on the pan, leaving a little space between slices.

Step 3: Roast until caramelized

Roast for 30 to 35 minutes, flipping the slices halfway through, until the edges are deeply golden and caramelized and the centers are fork-tender. If the glaze darkens too fast, tent the pan loosely with foil for the last 5 minutes.

Step 4: Finish and serve

Drizzle with a little extra maple syrup and sprinkle with thyme or rosemary and toasted pecans, if using. Serve warm, straight from the pan or transferred to a serving bowl.

Tips

• Do not crowd the pan: Slices that touch will steam instead of caramelizing. Use two pans if yours is small.
• Cut evenly: A mandoline or a steady knife helps, but the key is matching thickness, not perfect circles.
• Watch the last 5 minutes: Maple goes from caramelized to burnt quickly, so check often near the end.
• Make them ahead: Roast up to a day ahead, refrigerate, and reheat at 375°F (190°C) for 10 minutes until hot.

Storage

Refrigerate leftovers in an airtight container for up to 4 days. Reheat in a 375°F (190°C) oven for 8 to 10 minutes to crisp the edges again, or warm gently in a skillet. Freeze for up to 2 months; thaw overnight in the fridge before reheating.

Frequently Asked Questions

Can I cut the sweet potatoes into cubes instead of slices?

Yes. Cut them into 1-inch (2.5 cm) cubes and roast for the same time, flipping once. Cubes caramelize on more sides, so check them at 30 minutes.

Do I need to peel the sweet potatoes?

Peeling gives the smoothest, glossiest result, but unpeeled slices work too. Scrub them well, and add 3 to 5 minutes to the roast time if the skins are thick.

Can I use honey instead of maple syrup?

You can, but the flavor will be different and honey browns faster. Use the same amount and check the pan at 25 minutes so the glaze does not burn.

Why are my sweet potatoes soft instead of caramelized?

The pan was likely crowded or the oven was not hot enough. Spread the slices in a single layer, keep the oven at 425°F (220°C), and roast on the lowest rack for the last 5 minutes.
