Melting Sweet Potatoes with Maple Pecan Sauce (Thanksgiving Favorite!)

These melting sweet potatoes will be the first thing to disappear from your Thanksgiving table! Roasted in butter until crispy and golden on the outside while remaining fluffy and velvety on the inside, they’re absolutely irresistible. Top them with an easy maple pecan sauce or serve them plain—either way, they’re guaranteed to be everyone’s favorite side dish.

Why You’ll Love These Melting Sweet Potatoes

The secret to these incredible sweet potatoes is simple: roasting in butter instead of oil. Butter creates a golden, crispy exterior that oil simply can’t achieve, while keeping the insides perfectly tender. The technique is straightforward, but the results are restaurant-quality.

What makes these sweet potatoes special:

• Crispy, golden exterior with fluffy interior
• Roasted in butter for superior flavor and texture
• Optional 2-ingredient maple pecan sauce
• Perfect for Thanksgiving or any meal
• Easy enough for weeknight dinners
• Can be made ahead and reheated
• Works in the oven or air fryer

Ingredients for Melting Sweet Potatoes

For the Sweet Potatoes:

• 2 pounds fresh sweet potatoes (orange variety)
• 4 tablespoons (1/2 stick) unsalted butter
• 1/2 teaspoon salt

For the Maple Pecan Sauce (Optional):

• 1/2 cup pure maple syrup (grade B preferred)
• 1/2 cup chopped pecans

How to Make Melting Sweet Potatoes

Step 1: Prepare the Sweet Potatoes

Preheat your oven to 425°F (220°C). Peel the sweet potatoes and slice them into 1-inch thick round disks. Try to keep the slices uniform in thickness so they cook evenly. For Thanksgiving, plan on slightly less than one pound per person; for a regular meal, use about one pound per person.

Step 2: Arrange on Roasting Pan

Scatter the sweet potato disks on a roasting pan in a single layer, making sure they’re not touching each other. This space allows them to get crispy instead of steaming.

Step 3: Add Butter and Season

Melt 4 tablespoons of butter (2 tablespoons per pound of sweet potatoes). Drizzle the melted butter over the sweet potato slices. If you’re planning to use the maple pecan sauce, sprinkle with a light amount of salt. If serving plain, use 1/4 teaspoon salt per pound. Toss the slices to coat them evenly with butter.

Step 4: First Roast

Redistribute the slices in a single layer on the pan, making sure they’re not touching. Roast for 20 minutes until the bottom sides are golden brown and crispy. Resist the urge to eat one now—they’re about to get even better!

Step 5: Flip and Continue Roasting

Using tongs, carefully flip each sweet potato disk over. Roast for another 20 minutes until both sides are golden brown and crispy, and the insides are light and fluffy. The total roasting time is 40 minutes.

Step 6: Make the Maple Pecan Sauce (Optional)

While the sweet potatoes finish roasting, make the sauce. In a small saucepan, bring the maple syrup to a boil. Add the chopped pecans and return to a boil. Cook for 1 minute, then remove from heat. The sauce is ready!

Step 7: Serve

Transfer the melting sweet potatoes to a serving platter. Drizzle with the maple pecan sauce or serve plain. Enjoy immediately while they’re hot and crispy!

Expert Tips for Perfect Results

• Don’t let slices touch – Space between slices is crucial for crispiness
• Use butter, not oil – Butter creates superior browning and flavor
• Keep slices uniform – Same thickness = even cooking
• Don’t skip flipping – Both sides need direct heat for crispiness
• Use a roasting pan – Not a baking sheet with sides; air circulation matters
• Toast pecans first – For extra flavor, toast pecans before adding to syrup
• Use real maple syrup – No imitation pancake syrup
• Adjust salt – Less if using the sweet sauce, more if serving plain

Frequently Asked Questions

Can I use other varieties of sweet potatoes?

The recipe has been tested with orange sweet potatoes. Other varieties may work but could have different cooking times and moisture levels. If you try other types, let us know in the comments!

Why use butter instead of oil?

Butter creates a superior golden brown, crispy exterior that oil simply cannot achieve. It also adds incredible flavor. This is the key to making these sweet potatoes “melt in your mouth.”

Can I make these ahead for Thanksgiving?

Yes! See the make-ahead instructions section above. The best method is to partially roast them 1-2 days ahead, then finish roasting on serving day for maximum crispiness.

Do these work in an air fryer?

Absolutely! Preheat to 400°F and cook for 10 minutes per side (18-20 minutes total). You may need to work in batches depending on your air fryer size.

Can I double this recipe?

Yes! Use two roasting pans and 4 pounds of sweet potatoes with 8 tablespoons of butter. Roast both pans simultaneously, rotating their positions halfway through cooking.

Why aren’t my sweet potatoes getting crispy?

Make sure the slices aren’t touching each other on the pan. Overcrowding causes steaming instead of roasting. Also ensure your oven temperature is accurate—use an oven thermometer to check.

Can I skip the maple pecan sauce?

Absolutely! These melting sweet potatoes are delicious plain. The sauce is entirely optional, though it does make them extra special for holidays.

How do I reheat leftovers without losing crispiness?

The oven method is best: reheat at 400°F for 8-10 minutes. Avoid the microwave, which makes them soggy.

Can I use salted butter?

You can, but reduce the added salt to just a pinch or omit it entirely to avoid overly salty sweet potatoes.

How far in advance can I slice the sweet potatoes?

You can slice them up to 1 day ahead. Store in a container covered with water in the refrigerator. Drain and pat completely dry before using.
