These oven baked 3-ingredient maple glazed sweet potatoes are the kind of recipe you remember because of how simple and reliable they are. My sister shared this trick with me years ago: skip the butter, skip the spices, and let just three ingredients do all the work. The natural sweetness of the potatoes concentrates in the oven, while pure maple syrup and a pinch of salt create a glossy, sticky glaze that clings to every slice. It’s a very Midwestern approach at heart—unfussy, practical, and deeply comforting—yet the flavors feel a bit like something you’d find in a cozy bistro.
Serve these maple glazed sweet potatoes alongside roast chicken, pork tenderloin, or seared salmon, where their gentle sweetness balances savory main dishes. They also work beautifully on a holiday table next to turkey, green beans, and a crisp salad with a tangy vinaigrette to cut through the richness. For a simple weeknight meal, pair them with sautéed greens and a pot of lentils or black beans. Leftovers are excellent at room temperature, tucked into grain bowls with quinoa or farro, toasted nuts, and a squeeze of lemon for contrast.
Oven Baked 3-Ingredient Maple Glazed Sweet PotatoesServings: 4
Ingredients
2 pounds sweet potatoes, peeled and cut into 1/2-inch thick rounds
1/4 cup pure maple syrup
3/4 teaspoon fine sea salt
Directions
Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet completely with aluminum foil, shiny side up, pressing it into the corners so it lies flat. This helps the glaze stay on the potatoes instead of burning onto the pan and makes cleanup easy.
Place the sweet potato rounds in a large mixing bowl. Drizzle the maple syrup over the potatoes and sprinkle the salt evenly on top.
Toss the sweet potatoes thoroughly with your hands or a large spoon until every slice is lightly coated in maple syrup and the salt is evenly distributed. You want a thin, glossy film on each piece rather than a puddle of syrup at the bottom of the bowl.
Spread the sweet potatoes out in a single layer on the foil-lined baking sheet, laying the slices flat and not overlapping. If any syrup remains in the bowl, scrape it over the tops of the potatoes so it bakes into the glaze instead of being wasted.
Place the baking sheet on the middle rack and bake for 20 minutes. The sweet potatoes should be starting to soften and look slightly matte on the surface.
Using a thin spatula, gently flip each sweet potato slice. As you flip, scoop up any syrupy juices on the foil and drag them over the tops of the slices so they’re coated again. Return the pan to the oven.
Bake for another 10 to 15 minutes, or until the sweet potatoes are very tender when pierced with a fork and the maple syrup on the foil has thickened into a sticky, shiny glaze that clings to the edges of the slices. Watch closely toward the end; you want deep caramelization, not burning.
Remove the pan from the oven and let the sweet potatoes rest on the hot sheet for 5 minutes. During this time, the glaze will thicken further and adhere to the potatoes. Use the spatula to gently loosen any slices that stick to the foil, flipping them once more to pick up as much of the sticky glaze as possible before transferring to a serving dish. Serve warm, spooning any remaining glaze from the foil over the top.
Variations & Tips
Because this recipe is intentionally just three ingredients, the key is to choose them well: fresh, firm sweet potatoes, real maple syrup (not pancake syrup), and a salt that dissolves easily. From there, you can adapt the method in a few ways while still honoring the spirit of the recipe. If you’d like a slightly less sweet result, cut the maple syrup back to 3 tablespoons and increase the baking time by 5 minutes to deepen the caramelization. For crisper edges, use two baking sheets so the slices have more space and roast on convection if your oven has that setting, checking a few minutes early. If you need to make this ahead, roast as directed, cool on the sheet, and rewarm in a 350°F (175°C) oven for 10 to 15 minutes; the glaze will loosen slightly and then reset. You can also cut the sweet potatoes into thick wedges instead of rounds—just add a few extra minutes of baking time and flip once they take on color. For a more savory-leaning meal, serve the sweet potatoes with a squeeze of lemon or a spoonful of plain yogurt at the table; the acidity balances the maple without changing the core three-ingredient recipe.
