How to Make Sticky Smashed Sweet Potatoes
Step 1: Boil the Potatoes
Peel and slice sweet potatoes into thick rounds.
Boil in salted water for 5–8 minutes until just fork-tender.
Step 2: Make the Seasoning Mix
In a bowl, mix olive oil, cornstarch, garlic powder, sriracha, and black pepper until smooth.
Step 3: Smash the Potatoes
Drain the potatoes and arrange on a baking tray.
Cover each slice with parchment and gently smash with a flat-bottom glass until about 1 cm thick.
Step 4: Season & Roast
Brush both sides with the cornstarch mixture.
Bake or air fry at 180°C (350°F) for 30–40 minutes, flipping halfway through.
Step 5: Make the Garlic Yogurt Dip
Mix thick Greek yogurt with garlic powder or fresh garlic, plus salt and pepper to taste.
Chill until ready to serve.
Step 6: Glaze with Honey
When the potatoes are nearly done, drizzle with honey and return to the oven for a few more minutes until sticky.
Step 7: Serve
Remove from the oven, season lightly with flaked sea salt, and serve hot with the yogurt dip on the side.

FAQs
Can I make these ahead of time?
Yes! Smash and season the potatoes ahead, then roast before serving.
Do I have to peel the sweet potatoes?
Peeling gives a smoother texture, but feel free to leave the skin on if preferred.
Can I use regular yogurt instead of Greek?
You can, but Greek yogurt is thicker and gives a better dip consistency.
Are these very spicy?
They have a gentle kick, but you can adjust the sriracha to taste.
What’s the best way to smash the potatoes?
Use a glass or flat-bottom dish with parchment paper to avoid sticking.
