These Thai sweet potato skins turn roasted sweet potatoes into crisp shells filled with a creamy peanut and coconut mash. Lime, red chili, and lemongrass paste bring bright flavor, and chopped peanuts and green onions add crunch on top.
Serve them as a gathering appetizer or a fun side dish. Most of the work is hands off while the potatoes roast, and the filling comes together in a single bowl.

Why This Thai Sweet Potato Skins Recipe Works
Roasting the potatoes whole keeps them moist inside while the skins firm up. A second trip to the oven turns the empty shells crisp, so each bite has crunch and creaminess.
The peanut sauce is salty, sweet, sour, and spicy at once. Peanut butter and coconut milk make it silky, lime and chili wake it up, and lemongrass adds a floral note.
Mashing the scooped potato with the sauce means every spoonful of filling is seasoned throughout rather than just on top.
Ingredients for Thai Sweet Potato Skins
- 3 medium sweet potatoes
- 3 tablespoons crunchy peanut butter
- 1 tablespoon lime juice, about half a lime
- 1/2 tablespoon low sodium soy sauce
- 1 red chili, finely chopped, divided
- 7 tablespoons canned coconut milk (100 ml)
- 1 teaspoon light brown sugar
- 1/4 teaspoon ground coriander
- 3 green onions, finely chopped, divided
- 1 teaspoon lemongrass paste
- 4 tablespoons unsalted peanuts, roughly chopped, for topping
Sweet potatoes. Choose medium potatoes of similar size so they bake evenly. Pierce them all over so steam can escape.
Peanut butter and coconut milk. Crunchy peanut butter adds texture, and coconut milk loosens the sauce into a creamy mash. Sunflower seed butter or tahini works for a nut free version.
Lime, soy sauce, and brown sugar. Lime adds acidity, soy sauce adds salt, and brown sugar balances the heat. Taste before filling and adjust.
Chili, green onions, and lemongrass. Chili brings heat, green onions add freshness, and lemongrass paste gives a citrusy aroma. Reserve some chili and green onion for topping.
Peanuts. Roughly chopped peanuts add crunch and echo the flavor of the sauce.
How to Make Thai Sweet Potato Skins
1. Bake the potatoes Heat the oven to 400 degrees F. Pierce the sweet potatoes with a fork and bake for 40 to 45 minutes, until cooked all the way through.
2. Make the sauce Stir the peanut butter, lime juice, soy sauce, half the chili, coconut milk, brown sugar, coriander, half the green onions, and lemongrass paste together until smooth.
3. Cool the potatoes Let the potatoes cool for 10 minutes while the oven stays on.
4. Scoop and crisp Cut the potatoes in half lengthwise, scoop the flesh into a bowl, and place the skins on a tray. Bake the skins for 5 more minutes to crisp.
5. Mix the filling Mash the scooped potato with the peanut sauce using a fork until combined.
6. Fill and heat Spoon the mixture into the crisp skins and bake for 10 more minutes to heat through.
7. Top and serve Top with the reserved chili, green onions, and chopped peanuts, then serve warm.
How to Serve Thai Sweet Potato Skins
Serve the skins warm as an appetizer with a bowl of sweet chili sauce for dipping. For a full meal, pair them with satay chicken skewers and creamy Asian cucumber salad, or add a scoop of cilantro lime rice on the side. A glass of strawberry pineapple mojito makes a refreshing match for the spicy peanut flavor.
How to Store and Reheat Thai Sweet Potato Skins
Refrigerate leftover skins in an airtight container for up to 3 days. Reheat them on a tray in a hot oven until steaming and crisp again, and make sure the filling reaches 165 degrees F. The microwave warms them quickly but softens the skins. The stuffed skins do not freeze well, so enjoy them within a few days.
Tips and Variations for Thai Sweet Potato Skins
Pierce well. Poke the potatoes several times so steam escapes and the skins do not pop.
Choose even sizes. Similar sized potatoes finish baking together.
Check doneness. A knife should slide in easily and the potato should feel soft all the way through.
Crisp the shells. Do not skip the second bake for the empty skins. It keeps them from turning soft once filled.
Adjust the heat. Remove the chili seeds for a milder filling, or add extra for more kick.
Make it nut free. Swap the peanut butter for sunflower seed butter or tahini and top with toasted seeds.
Prep ahead. Bake the potatoes and mix the sauce a day ahead, then assemble just before serving.
Reheat safely. Reheat leftovers until hot throughout, and follow the University of Wisconsin Extension leftovers guidance for chilling.
