Sweet Potato Bites with Marshmallows & Pecans turn creamy, naturally sweet potatoes into an easy bite-size side dish with a buttery pecan crunch and toasted marshmallow topping. Each piece combines soft sweet potato with crisp nuts and lightly browned marshmallows for a festive contrast of textures.
These bites are especially useful for holiday meals because they can be assembled ahead and baked just before serving. Roasting the sweet potatoes first concentrates their flavor while keeping the pieces sturdy enough to hold their toppings.
Why This Recipe Works
- Roasting concentrates the sweet potato flavor: High heat develops caramelized edges while keeping the centers tender.
- Thick slices hold their shape: Cutting the sweet potatoes into 1/2-inch rounds gives each bite enough structure for the toppings.
- Maple syrup complements the natural sweetness: A small amount adds depth without making the dish overly sugary.
- Pecans add needed texture: Buttery chopped nuts provide crunch against the soft sweet potato and marshmallows.
- A short second bake toasts the marshmallows: The toppings brown quickly without giving the sweet potatoes time to dry out.
Equipment Needed
- Large rimmed baking sheet

Ingredients List
Sweet Potato Bites
- 2 large sweet potatoes, about 2 lb (900 g), peeled and sliced into 1/2-inch rounds
- 2 tablespoons unsalted butter, 1 oz (28 g), melted
- 2 tablespoons pure maple syrup, 30 mL
- 1 teaspoon ground cinnamon, 3 g
- 1/4 teaspoon kosher salt, 1.5 g
Pecan Topping
- 1/2 cup pecans, about 55 g, finely chopped
- 1 tablespoon packed light brown sugar, 12 g
- 1 tablespoon unsalted butter, 1/2 oz (14 g), melted
Marshmallow Topping
- 1 1/2 cups mini marshmallows, about 75 g
Ingredient Notes and Substitutions
- Sweet potatoes: Choose firm, similarly sized sweet potatoes so the slices cook at the same rate. Garnet or jewel sweet potatoes work well. Avoid very thin slices because they can become too soft to hold the toppings.
- Pure maple syrup: It adds a subtle caramel-like flavor to the sweet potatoes. Honey can be substituted, although it will give the bites a slightly different sweetness and can brown more quickly.
- Pecans: Their rich, buttery flavor works especially well with sweet potatoes. Walnuts are a reasonable substitute, but they have a firmer, slightly more bitter flavor.
- Mini marshmallows: They melt and brown quickly, making them ideal for the short finishing bake. Larger marshmallows can be cut into smaller pieces, but they may take longer to toast evenly.
- Unsalted butter: Butter helps the sweet potato edges brown and gives the pecan topping a richer texture. Salted butter can be used; if so, reduce or omit the added kosher salt.
Step-by-Step Instructions
Step 1: Heat the oven.
Preheat the oven to 425°F (220°C). Line a large rimmed baking sheet with parchment paper.
Step 2: Slice the sweet potatoes.
Peel the sweet potatoes and cut them crosswise into rounds about 1/2 inch thick. Try to keep the slices similar in thickness so they roast evenly.
Step 3: Season the sweet potatoes.
Place the sweet potato rounds in a large bowl. Add the 2 tablespoons melted butter, 2 tablespoons maple syrup, 1 teaspoon cinnamon, and 1/4 teaspoon kosher salt. Toss until the slices are evenly coated.
Step 4: Arrange for roasting.
Place the sweet potato rounds in a single layer on the prepared baking sheet, leaving a little space between them. If the slices are crowded, they will steam more than roast.
Step 5: Roast until tender.
Roast for 20–25 minutes, turning the rounds carefully about halfway through. They should be tender when pierced with a fork, with lightly browned edges. If the centers are still firm, continue roasting for a few minutes.
Step 6: Prepare the pecan topping.
While the sweet potatoes roast, combine the 1/2 cup chopped pecans, 1 tablespoon brown sugar, and 1 tablespoon melted butter in a small bowl. Stir until the pecans are evenly coated and crumbly.
Step 7: Add the toppings.
Remove the sweet potatoes from the oven. Reduce the oven temperature to 400°F (200°C). Spoon a small amount of the pecan mixture onto each sweet potato round, then top with a few mini marshmallows. Keep the marshmallows mostly centered so they do not slide off as they melt.
Step 8: Toast the marshmallows.
Return the baking sheet to the oven and bake for 5–7 minutes, watching closely. The marshmallows should be puffed and lightly golden, while the pecans should look toasted but not dark.
Step 9: Serve warm.
Let the bites stand for about 5 minutes before transferring them to a serving platter. Serve warm while the sweet potatoes are tender and the marshmallow topping is soft.
Storage, Freezing, and Make-Ahead Instructions
- For the best texture, serve these bites shortly after baking. Leftovers can be refrigerated in an airtight container for up to 3 days . The marshmallows will soften during storage.
- To make ahead, roast the sweet potato rounds up to 1 day in advance and refrigerate them in a covered container. Prepare the pecan topping separately and refrigerate it. When ready to serve, bring the sweet potatoes and topping out of the refrigerator, assemble with the marshmallows, and bake at 400°F (200°C) until heated through and the marshmallows are golden, about 8–10 minutes .
- Freezing is not recommended because the roasted sweet potato texture and marshmallow topping can become soft and watery after thawing.
FAQ
Can I use canned sweet potatoes?
Canned sweet potatoes are not recommended for this version because they are already soft and difficult to cut into sturdy rounds. Fresh sweet potatoes hold their shape better during roasting and topping.
Can I make these sweet potato bites ahead of time?
Yes. Roast the sweet potato rounds and prepare the pecan mixture up to 1 day ahead. Refrigerate them separately, then add the marshmallows and finish baking shortly before serving.
Can I use walnuts instead of pecans?
Yes. Chopped walnuts are a good substitute, although they have a slightly firmer texture and less buttery flavor than pecans.
How do I keep the marshmallows from burning?
Use mini marshmallows and watch them closely during the final bake. They only need a few minutes at 400°F (200°C) to puff and brown.
Can I make larger sweet potato bites?
Yes, but larger rounds will need more topping and may require additional roasting time. Keep the slices close to 1/2 inch thick so they remain sturdy without becoming difficult to cook through.
