Smashed Sweet Potatoes
- 600g sweet potato
- 2 1/2 tbsp olive oil
- 2 tbsp cornstarch
- 1/2 tsp garlic powder
- 1 tsp sriracha
- 1/2 tsp freshly cracked black pepper
- 1/2 – 1 tsp flaked sea salt (add to taste)
- 1 tsp honey
Garlic Yoghurt Sauce
- 1/4 cup (90g) thick Greek-style yoghurt
- Salt and pepper to taste
- 1/2 tsp garlic powder or 1 clove finely chopped garlic (choose according to preference)
- Prepare the sweet potatoes: Peel and cut the sweet potatoes into 3 cm thick slices. Boil them in salted water for 5 to 8 minutes, or until they can be easily pierced with a knife.
- Make the coating mixture: While the potatoes are cooking, combine olive oil, cornstarch, garlic powder, sriracha, freshly cracked black pepper, and flaked sea salt (excluding the honey) in a bowl to create the cornflour and oil mixture.
- Drain and smash the potatoes: Drain the cooked sweet potato slices and place them in a single layer on a baking tray. Place a small square of baking paper on top of each slice, then use a glass or sturdy container to gently smash each sweet potato slice until it is just under 1 cm thick.
- Coat the smashed slices: Brush the cornflour and oil mixture generously over the top of the smashed sweet potatoes, then carefully flip them over and coat the other side as well.
- Bake or air fry the potatoes: Place the tray in a preheated oven or air fryer at 180°C (350°F) and cook for 30 to 40 minutes, or until the sweet potatoes are crispy and golden brown. Flip the slices halfway through cooking to ensure even crisping.
- Prepare the garlic yoghurt sauce: While the sweet potatoes cook, season the Greek yoghurt with salt and pepper to taste. Optionally, stir in garlic powder or finely chopped garlic to add a garlicky flavor to the dip.
- Add honey and finish cooking: When the sweet potatoes are nearly done, drizzle the honey evenly over them and return to the oven or air fryer for the final few minutes until the honey is sticky and caramelized.
- Serve: Remove the sweet potatoes from the oven or air fryer, add additional salt and pepper if desired, and serve immediately with the garlic yoghurt dipping sauce.
Notes
- Adjust the amount of sriracha and garlic according to your taste preference for spice and pungency.
- Using baking paper when smashing helps prevent the potatoes from sticking and keeps the texture intact.
- For extra crispiness, you can use an air fryer instead of a traditional oven.
- The honey adds a lovely contrast of sweetness, but can be omitted or substituted with maple syrup for a vegan option.
- The garlic yoghurt sauce can be made dairy-free by using plant-based yoghurt alternatives.
- Be careful not to over-smash the sweet potatoes to prevent them from breaking apart completely.
