How to Make Crispy Smashed Sweet Potatoes

Step 1: Prep the Sweet Potatoes
Peel and slice sweet potatoes into thick rounds.

Boil until fork-tender, about 5–8 minutes. Drain well.

Step 2: Make the Oil Mixture
While potatoes cook, whisk together olive oil, cornstarch, garlic powder, sriracha, black pepper, and salt.

Step 3: Smash and Season
Arrange sweet potatoes on a tray.

Use parchment and a glass to gently smash each piece to about 1cm thick.

Brush both sides with oil mixture.

Step 4: Bake or Air Fry
Cook at 180°C (350°F) for 30–40 minutes, flipping halfway, until crisp and golden.

Step 5: Add Honey Glaze
In the last few minutes, drizzle with honey and return to oven or air fryer to caramelize.

Step 6: Make the Yogurt Sauce
Mix Greek yogurt with salt, pepper, and garlic powder or fresh minced garlic.

Step 7: Serve and Enjoy
Plate sweet potatoes, sprinkle extra sea salt, and serve with yogurt sauce on the side.
