Asondo (Nigerian Dried Sweet Potatoes)

Pin it

Introduction

Asondo is a West African dried snack made from boiled sweet potato slices that are sun-dried or dehydrated until crispy and chewy. The process concentrates the natural sweetness while creating a shelf-stable snack you can make in bulk and portion into jars. This recipe requires just two ingredients and minimal active work—most of the time is hands-off drying.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 30 minutes (plus 2–3 days drying time)
• Total Time: 2–3 days
• Servings: 8–10 (as a snack)

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

Thinner slices for crispier texture: Cut potatoes to ¼-inch thickness instead of thicker pieces to reduce drying time to 1–2 days and create a more brittle, chip-like final product.

Add cinnamon or nutmeg during boiling: Stir ½ teaspoon of ground cinnamon or nutmeg into the boiling water before adding potatoes for subtle warm spice throughout the finished snack.

Mixed root vegetable batch: Combine sliced sweet potatoes with peeled and sliced regular potatoes or cassava root in equal amounts; boil together and dry on the same schedule for variety and texture contrast.

Honey or maple drizzle (post-drying): Once fully dried and cooled, lightly brush or drizzle with honey or maple syrup and let it air-dry for 30 minutes for added sweetness and a light glaze.

Oven-drying method: If sun-drying is not practical, arrange boiled slices on parchment-lined baking sheets and dry in a 200°F oven for 4–6 hours, stirring halfway through, until crispy.

Tips for Success

Don’t skip the boiling step. Boiling softens the potato and begins the cooking process, which speeds up drying and ensures even texture throughout the finished snack.

Slice uniformly. Cut all pieces to roughly the same thickness so they dry at the same rate; thicker pieces will stay chewy while thin ones become brittle if you’re not careful.

Test for crispness before storing. A fully dried slice should snap cleanly when bent and have no moisture when you squeeze it; any softness or bend means it needs more drying time to prevent mold.

Ensure good air circulation during sun-drying. Lay slices on clean cloth or mesh in a single layer, and turn them once halfway through to expose all sides evenly to air and light.

Store in an airtight container once fully cooled. Moisture trapped in warm asondo will cause it to soften or develop mold, so let it cool completely to room temperature before sealing.

Storage and Reheating

Store fully dried asondo in an airtight glass jar or container at room temperature for up to 2 weeks, or in the refrigerator for up to 4 weeks for extended freshness. For longer storage, freeze in a freezer bag for up to 3 months; thaw at room temperature before opening to prevent condensation.

Asondo does not require reheating—eat it as a snack straight from the jar. If pieces soften during storage due to humidity, spread them on a baking sheet and crisp them in a 200°F oven for 10–15 minutes, then cool completely before returning to the jar.

FAQ

Can I use white potatoes or other root vegetables instead of sweet potatoes?

Yes, regular potatoes, cassava, or plantains will work with the same boiling and drying method, though the flavor and drying time will differ slightly. Cassava tends to dry faster, while regular potatoes take longer and are less naturally sweet.

Why does my asondo get soft or develop a chewy texture instead of staying crispy?

This typically means it was not dried long enough or moisture was reintroduced during storage. Ensure slices are completely brittle before sealing in a jar, and store in an airtight container in a dry location away from humidity.

How do I know when the boiling is done?

Boil for about 10–15 minutes, until the potato slices are just tender when pierced with a fork but still hold their shape—they should not be soft or falling apart.

Can I speed up the drying process?

Yes, use a food dehydrator at 135–150°F for 6–8 hours (following your dehydrator’s manual), or oven-dry at 200°F for 4–6 hours. Both methods give you more control over final texture than sun-drying.
