Ingredients You’ll Need

• Sweet potatoes: Two large sweet potatoes provide the base for this recipe. Look for potatoes that are relatively uniform in thickness so the rounds cook evenly.
• Avocado oil spray: A light coating helps the sweet potato rounds develop slightly crispy edges under the broiler.
• Salt and pepper: A little seasoning balances the natural sweetness of the potatoes and the sugary topping.
• Finely chopped pecans: Pecans give the crumble its signature nutty flavor and crunchy texture. Finely chopped pieces make it easier to portion the topping onto each round.
• Brown sugar: Brown sugar adds sweetness and a warm molasses flavor that pairs beautifully with sweet potatoes and pecans.
• All-purpose flour: Flour helps bind the crumble ingredients together and gives the topping its crumbly texture.
• Salted butter: Melted butter brings richness to the pecan topping and helps the brown sugar and flour form a delicious crumble.
• Mini marshmallows: A few mini marshmallows on each round create the classic sweet potato casserole finish. They puff up and turn golden when briefly returned to the oven. I love Dandies!

How to Make Smashed Sweet Potato Casserole Bites

Step 1: Prepare the Sweet Potatoes

Preheat your oven to broil and line a large baking sheet with parchment paper. Bring a large pot of water to a boil. Slice the sweet potatoes into rounds about 1 inch thick. Depending on their length, you should get approximately 8–12 rounds per potato. Add the rounds to the boiling water and cook until they’re fork-tender but not falling apart. Start checking at about 15 minutes, since the exact cooking time will depend on the thickness of your slices. Drain the sweet potatoes carefully and allow them to cool for approximately 10 minutes. This makes them easier to handle during the next step.

Step 2: Make the Pecan Crumble

While the sweet potatoes are boiling, prepare the topping. In a medium bowl, combine the finely chopped pecans, brown sugar, flour, melted salted butter, and a small pinch of salt. Stir until the ingredients are evenly mixed and form a crumbly texture. Set the mixture aside while you prepare the sweet potatoes.

Step 3: Smash the Sweet Potato Rounds

Arrange the cooked sweet potato rounds in a single layer on your prepared baking sheet. Using the flat bottom of a measuring cup, gently press each round until it’s slightly flattened. The goal is to create a little extra surface area for the topping while keeping each round intact. Avoid smashing them too hard. If the sweet potatoes become too thin or break apart, they may not hold the crumble as well. Lightly spray the rounds with avocado oil and season with a small pinch of salt and pepper.

Step 4: Crisp the Edges

Place the baking sheet under the broiler for approximately 3–5 minutes, watching carefully until the edges begin to crisp. Broilers can brown food quickly, so keep a close eye on the sweet potatoes to prevent burning. Remove the baking sheet from the oven and reduce the oven temperature to 425°F.

Step 5: Add the Pecan Crumble

While the oven temperature adjusts, spoon a heaping tablespoon of the pecan crumble onto each sweet potato round. Spread the topping gently over the center of each round, allowing some of the edges to remain visible. Return the baking sheet to the oven and bake for approximately 18 minutes, or until the crumble is golden brown and fragrant.

Step 6: Add the Marshmallows

Remove the sweet potatoes from the oven and top each round with a few mini marshmallows. Return the baking sheet to the oven for another 1–3 minutes, just until the marshmallows puff up and turn golden brown. Watch closely during this final step. Marshmallows can go from perfectly toasted to overly browned very quickly.

Step 7: Cool and Serve

Remove the sweet potato bites from the oven and let them cool for about 5 minutes before serving. The topping will be hot straight from the oven, so a brief cooling period makes the bites easier to handle while allowing the crumble to settle. Arrange them on a serving platter and enjoy!

Tips for the Best Sweet Potato Casserole Bites

Choose evenly sized sweet potatoes. Potatoes with similar thickness will produce more uniform rounds, helping everything cook at approximately the same rate.

Don’t overboil the sweet potatoes. The rounds should be fork-tender but still firm enough to hold their shape. Overcooking can make them difficult to smash and transfer without breaking.

Let the potatoes cool slightly. Giving them about 10 minutes to cool after draining helps them firm up enough to handle.

Smash gently. You want flattened rounds, not mashed sweet potatoes. A measuring cup works well because its flat bottom distributes pressure evenly.

Watch the broiler carefully. The initial broiling step helps crisp the edges, but the high heat can quickly scorch the potatoes. Keep an eye on them throughout.

Use finely chopped pecans. Smaller pieces distribute more evenly throughout the crumble, making it easier to top each round and helping the mixture stay in place.

Toast the marshmallows at the very end. Adding marshmallows too early can cause them to melt excessively or burn before the pecan topping is ready.

Can You Make Sweet Potato Casserole Bites Ahead of Time?

Yes! A little advance preparation can make holiday cooking much easier.

You can prepare the pecan crumble ahead of time and store it in an airtight container in the refrigerator until you’re ready to use it. You can also boil and slice the sweet potatoes in advance, allowing them to cool before refrigerating them in a covered container.

For the best texture, assemble and bake the bites closer to serving time. This helps preserve the crisp edges and keeps the marshmallows looking freshly toasted.

If you’re preparing these for Thanksgiving or Christmas, consider making the crumble the day before and cooking the sweet potatoes earlier in the day. Then you can smash, crisp, top, and finish them shortly before dinner.

What to Serve With Sweet Potato Casserole Bites

These sweet potato bites are a natural fit for a holiday spread, but they’re versatile enough to serve with plenty of everyday meals, too.

For Thanksgiving, serve them alongside roast turkey, stuffing, gravy, green beans, and cranberry sauce. Their sweet, nutty flavor complements savory main dishes and traditional holiday sides.

At Christmas dinner, pair them with roasted ham, beef tenderloin, or roast chicken. They also make a lovely addition to a fall potluck or family gathering.

How to Store and Reheat Leftovers

If you have leftovers, allow the sweet potato bites to cool and transfer them to an airtight container. Refrigerate promptly and use within 3–4 days. To reheat, arrange the bites on a baking sheet and warm them in a 350°F oven until heated through. Keep an eye on the marshmallows, as they may brown further during reheating. An air fryer can also work for reheating smaller portions; use a lower temperature and check frequently.

The topping may soften slightly after refrigeration, but reheating in the oven or air fryer can help restore some of the texture.

Frequently Asked Questions

Are Smashed Sweet Potato Casserole Bites a side dish or a dessert?

They’re best served as a sweet holiday side dish, especially alongside savory Thanksgiving and Christmas favorites. However, their brown sugar pecan crumble and toasted marshmallows give them a dessert-like quality, making them a fun addition to a potluck or festive buffet.

Can I use regular potatoes instead of sweet potatoes?

You can experiment with different types of sweet potatoes, but not regular potatoes. Sweet potatoes have a naturally sweet, creamy interior that pairs especially well with brown sugar, pecans, and marshmallows.

Can I substitute the pecans?

Yes. Chopped walnuts can provide a similar crunchy texture and nutty flavor. If you have a nut allergy, omit the pecans and consider using a suitable nut-free crumble instead.

How do I keep the sweet potato rounds from falling apart?

The key is to avoid overcooking the potatoes and to let them cool slightly before smashing. Slice them into rounds about 1 inch thick and press gently with the bottom of a measuring cup rather than flattening them completely.

Can I make these without marshmallows?

Absolutely! The brown sugar pecan crumble is delicious on its own. Simply skip the marshmallows and serve the bites once the topping is golden brown.
