Asondo (Nigerian Dried Sweet Potatoes)

PIn it

Introduction

Asondo is a Nigerian snack of dried sweet potato slices—crispy, naturally sweet, and shelf-stable for weeks. The recipe requires only two ingredients and relies on sun-drying or a dehydrator to concentrate flavor and create a satisfying crunch that works equally well as a standalone snack or crumbled into grain bowls and salads.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 15 minutes (boiling) + 2–3 days (sun-drying) or 6–8 hours (dehydrator)
• Total Time: 2–3 days or 6–8 hours (plus 15 minutes active work)
• Servings: 4–6 (as a snack or side)

Ingredients

• Sweet potatoes
• Water

Instructions

1. Slice sweet potatoes in desired shape and size.
2. Boil sweet potatoes.
3. Dry in the sun for 2 to 3 days or dehydrate using a dehydrator until crispy.

Variations

Thicker slices: Cut potatoes into ¼-inch slabs instead of thin rounds. They’ll take longer to dry but will have a chewier center and crispier exterior.

Seasoned version: Toss the boiled slices with a light coating of salt, smoked paprika, or ground ginger before drying for savory depth.

Partial boil: Reduce boiling time to 5 minutes instead of fully cooking through. The slices will take longer to dehydrate but will crisp up more evenly.

Oven-drying method: Arrange boiled slices on baking sheets and dry at 225°F for 4–6 hours, stirring halfway through, if sun-drying or a dehydrator isn’t available.

Mixed root vegetable: Combine thinly sliced sweet potatoes with parsnips or cassava in equal parts. Boil together and dry using the same method for variety.

Tips for Success

Boil until just tender: The potatoes should be easily pierced with a fork but still hold their shape. Overcooked slices will break apart during drying.

Pat dry before drying: After boiling, lay the slices on a clean cloth or paper towels for 5–10 minutes to remove surface moisture. This speeds up drying time.

Check for complete dryness: The slices should snap cleanly when bent. Any moisture remaining will cause mold during storage.

Sun-dry in a protected spot: Use a raised rack or screen to allow air circulation on all sides, and cover loosely with cheesecloth to keep insects away while allowing airflow.

Store in an airtight container: Once completely cool, transfer to a jar or sealed bag with a silica packet if you live in a humid climate.

Storage and Reheating

Store asondo in an airtight container or resealable bag at room temperature for up to 4 weeks, or in the freezer for up to 3 months (though texture will soften slightly when thawed). Keep a silica desiccant packet in the container if your kitchen is humid.

Asondo does not require reheating and is best eaten as-is. If slices have softened during storage, you can recrisp them in a 300°F oven for 5–10 minutes, then cool completely before eating.

FAQ

Can I use a regular oven instead of a dehydrator or sun-drying?

Yes. Arrange boiled, dried slices on a baking sheet and bake at 225°F for 4–6 hours, stirring halfway through, until fully crispy.

How do I know when the slices are done drying?

They should snap cleanly when you bend them and have no soft or chewy spots. Any give indicates residual moisture that will lead to spoilage.

Can I skip the boiling step?

Boiling softens the potatoes and shortens total drying time significantly. Raw slices will take much longer to dry and may not crisp evenly. It’s not recommended.

What’s the difference between sun-drying and using a dehydrator?

Sun-drying takes 2–3 days and depends on weather and humidity, while a dehydrator takes 6–8 hours with consistent, controlled results. Both produce the same final texture; use whichever method suits your climate and schedule.
