Ingredients You’ll Need

For the Crispy Smashed Sweet Potatoes

600g sweet potato
2½ tablespoons olive oil
2 tablespoons cornstarch
½ teaspoon garlic powder
1 teaspoon sriracha
½ teaspoon freshly cracked black pepper
½ to 1 teaspoon flaked sea salt
1 teaspoon honey

For the Garlic Yogurt Sauce

¼ cup thick Greek-style yogurt
Salt and pepper to taste
½ teaspoon garlic powder or 1 finely minced garlic clove

How to Make Crispy Smashed Sweet Potatoes

Step 1: Prepare the Sweet Potatoes

Peel the sweet potatoes and slice them into rounds about 3cm thick.

Bring a pot of salted water to a boil and cook the slices for 5 to 8 minutes. They should be fork-tender but still hold their shape.

Drain well.

Step 2: Make the Crispy Coating

While the potatoes cook, combine:

Olive oil
Cornstarch
Garlic powder
Sriracha
Black pepper
Salt

Mix until smooth.

This coating is the secret weapon behind those irresistible crispy edges.

Step 3: Smash the Potatoes

Arrange the boiled sweet potato slices in a single layer on a baking tray.

Place a small square of parchment paper over one slice. Using the bottom of a glass or measuring cup, gently press down until the potato is just under 1cm thick.

Repeat with all slices.

Don’t worry if a few edges crack. Those rough little edges often become the crispiest parts.

Step 4: Coat Both Sides

Brush the cornstarch mixture generously over each sweet potato.

Flip them carefully and brush the other side as well.

Getting both sides coated helps create maximum crunch.

Step 5: Bake or Air Fry

Cook at 180°C (350°F) for 30 to 40 minutes.

Halfway through cooking, flip the sweet potatoes so both sides become beautifully golden.

They are ready when the edges look deeply caramelized and crispy.

Step 6: Add the Honey Glaze

A few minutes before cooking is complete, drizzle honey over the sweet potatoes.

Return them to the oven or air fryer for the final few minutes.

The honey transforms into a glossy, sticky coating that perfectly balances the heat from the sriracha.

Step 7: Make the Garlic Yogurt Sauce

While the potatoes finish cooking, stir together:

Greek yogurt
Salt
Pepper
Garlic powder or fresh garlic

Mix until creamy and smooth.

Serve alongside the hot sweet potatoes for dipping.

Chef Omar’s Tips for Extra Crispy Results

A few simple tricks can take these from good to unforgettable.

Dry Them Well

After boiling, let the sweet potatoes steam dry for a minute or two. Less moisture means more crispiness.

Don’t Skip the Cornstarch

Cornstarch is the MVP here. It helps create that crunchy exterior everyone loves.

Give Them Space

Crowding the tray traps steam. Leave a little room between each piece so they crisp instead of soften.

Embrace the Cracks

When smashing, some pieces may split slightly around the edges. That’s not a mistake—it’s where the crunch happens.

Adjust the Heat

Love spice? Add extra sriracha.

Prefer things milder? Reduce it slightly and let the sweet potato’s natural sweetness shine.

A Fun Kitchen Memory

The first time I served these at a casual weekend gathering, I expected them to be a side dish.

Instead, they became the main attraction.

Everyone gathered around the tray, grabbing crispy pieces before they even made it to the serving plate. Surprisingly, the smashing process became part of the entertainment. There’s something oddly satisfying about turning simple sweet potatoes into crunchy golden rounds.

Since then, these have become a regular favorite whenever I need a crowd-pleasing snack or easy side dish.

Delicious Serving Ideas

These Crispy Smashed Sweet Potatoes work with so many meals.

They also make a fantastic afternoon snack with extra garlic yogurt sauce on the side.

Frequently Asked Questions

Do I cut the sweet potatoes before boiling?

Yes. Peel and slice them into thick rounds before boiling. This helps them cook evenly and makes the smashing step much easier.

Can I make Crispy Smashed Sweet Potatoes in an air fryer?

Absolutely.
An air fryer works beautifully for this recipe and often produces extra crispy edges.
Cook at 180°C (350°F) and flip halfway through cooking.

What if I accidentally cut the sweet potatoes too thin?

No problem.
Some cooks have skipped the smashing step entirely after slicing their sweet potatoes thinner than intended. The flavor remains fantastic, and they still crisp up nicely.

How do I store leftovers?

Store leftovers in an airtight container in the refrigerator for up to 3 days.
For the best texture, reheat in an oven or air fryer rather than a microwave.

Can I make them without honey?

Yes.
Maple syrup works well as a substitute, or you can omit the sweet glaze altogether if preferred.

Why aren’t my sweet potatoes crispy?

The most common reasons are:
Too much moisture after boiling
Overcrowding the tray
Not using enough cornstarch
Removing them before they’re fully golden
A few extra minutes of cooking can make a big difference.
