Ingredients
For these sweet potato rounds, the star is, of course, fresh sweet potatoes—choose firm, orange‑fleshed ones for the sweetest flavor and a smooth texture. The coating combines all‑purpose flour, cornstarch, and a blend of spices that give each round a delicate crunch. A quick glaze of maple syrup, soy sauce, Dijon mustard, and a touch of smoked paprika adds a glossy finish and layers of sweet, salty, and smoky notes. Finally, a sprinkle of fresh herbs brightens the dish just before serving.
Main Ingredients
- 2 large sweet potatoes (about 1½ lb)
- 2 tablespoons olive oil
Coating & Flour Mix
- ¼ cup all‑purpose flour
- 2 tablespoons cornstarch
- ½ teaspoon smoked paprika
- ½ teaspoon garlic powder
- ¼ teaspoon sea salt
- ¼ teaspoon freshly ground black pepper
Glaze (Sauce/Marinade)
- 3 tablespoons pure maple syrup
- 1 tablespoon low‑sodium soy sauce
- 1 teaspoon Dijon mustard
- ½ teaspoon apple cider vinegar
Seasoning & Garnish
- 2 tablespoons chopped fresh parsley (optional)
These ingredients work together to create a harmonious bite. The sweet potatoes supply natural sugars that caramelize during roasting, while the flour‑cornstarch blend forms a thin, crunchy shell. The glaze’s maple‑soy‑mustard balance adds depth without overwhelming the vegetable’s flavor, and the final parsley garnish injects a pop of color and fresh herbaceous lift that brightens the whole plate.
Step-by-Step Instructions
Preparing the Sweet Potatoes
Start by washing the sweet potatoes thoroughly, then pat them dry with a clean kitchen towel. Using a sharp mandoline or a sturdy chef’s knife, slice each potato into ½‑inch thick rounds—uniform thickness ensures even cooking and consistent crispness. Transfer the rounds to a large bowl, drizzle with 2 tablespoons olive oil, and toss until every piece is lightly coated. This thin oil layer helps the flour mixture adhere and promotes browning in the oven.
Coating & Roasting
- Mix the coating. In a shallow dish combine ¼ cup all‑purpose flour, 2 tablespoons cornstarch, ½ teaspoon smoked paprika, ½ teaspoon garlic powder, ¼ teaspoon sea salt, and ¼ teaspoon black pepper. Whisk until evenly blended; the cornstarch adds extra crunch.
- Dust the rounds. Sprinkle the flour mixture over the oiled sweet potato rounds, tossing gently until each slice is lightly coated. Excess flour should fall back into the bowl—too much coating can make the rounds gummy.
- Arrange on a baking sheet. Line a rimmed sheet pan with parchment paper. Lay the rounds in a single layer, leaving a small gap between pieces; crowding traps steam and prevents crisping.
- Roast. Preheat the oven to 425°F (220°C). Roast the rounds for 20‑25 minutes, flipping halfway through, until the edges turn golden brown and the centers are tender when pierced with a fork. The high heat creates a caramelized exterior while keeping the interior soft.
Glazing & Finishing
While the potatoes roast, whisk together 3 tablespoons maple syrup, 1 tablespoon soy sauce, 1 teaspoon Dijon mustard, and ½ teaspoon apple cider vinegar in a small saucepan. Bring to a gentle simmer over medium‑low heat, stirring constantly until the glaze thickens slightly—about 3‑4 minutes. Once the sweet potatoes are done, transfer them back to the bowl, pour the warm glaze over, and toss gently to coat each round evenly. Return the glazed rounds to the sheet pan for an additional 3‑4 minutes of baking; this step sets the glaze and adds a glossy finish. Remove from the oven, sprinkle 2 tablespoons chopped fresh parsley for color, and serve immediately while still crisp.
Tips & Tricks
Perfecting the Recipe
Uniform thickness. Use a mandoline or a ruler to keep every slice at exactly ½ inch; this guarantees even browning and prevents some rounds from becoming mushy while others stay raw.
Dry before oiling. Pat the potatoes completely dry after washing. Moisture interferes with crisp formation and can cause steam, resulting in soggy rounds.
Flavor Enhancements
Add a pinch of cayenne pepper to the coating for subtle heat, or finish with a drizzle of toasted sesame oil after glazing for an extra nutty aroma. A squeeze of fresh lemon juice right before serving brightens the sweet‑savory balance.
Common Mistakes to Avoid
Do not skip the flip halfway through roasting—without it, only one side will crisp. Also, avoid using too much glaze; an overly thick coating can make the rounds soggy instead of glossy.
Pro Tips
Use a convection oven. If your oven has a convection setting, use it to circulate hot air, which speeds up crisping and yields an even golden surface.
Pre‑heat the baking sheet. Placing the rounds on a hot sheet helps initiate immediate browning, reducing the chance of sogginess.
Make extra glaze. Reserve a small amount of glaze for dipping; it keeps the flavor alive even after the rounds have cooled slightly.
Serve immediately. The crunch is at its peak right out of the oven—if you need to hold them, keep them on a wire rack in a low‑heat oven (200°F) to preserve texture.
Variations
Ingredient Swaps
Replace sweet potatoes with thinly sliced carrots or parsnips for a different earthy sweetness. For a protein boost, add a sprinkle of toasted pumpkin seeds after glazing. If you prefer a sweeter profile, swap maple syrup for honey or agave nectar, which also adds a subtle floral note.
Dietary Adjustments
To keep the dish gluten‑free, substitute the all‑purpose flour with a 1:1 gluten‑free blend. For a vegan version, use a plant‑based oil (such as avocado oil) and ensure the soy sauce is wheat‑free. Keto‑friendly diners can replace the maple syrup with a low‑carb sweetener like erythritol and omit the cornstarch, using almond flour instead.
Serving Suggestions
These rounds shine as a party finger food with a side of cool yogurt‑herb dip, or as a side to grilled chicken or salmon. Pair them with a crisp mixed greens salad dressed in a light vinaigrette for a balanced plate, or stack them on mini sliders for a playful appetizer.
Storage Info
Leftover Storage
Allow the rounds to cool to room temperature, then transfer them to an airtight container. Store in the refrigerator for up to 3 days. For longer preservation, freeze in a single layer on a baking sheet, then move to a freezer‑safe bag; they’ll keep for up to 2 months without losing crispness.
Reheating Instructions
Re‑crisp leftovers by spreading the rounds on a baking sheet and heating in a 375°F oven for 10‑12 minutes, or until hot and the coating regains its crunch. Microwaving is not recommended, as it softens the crust; if you must, use a microwave‑crisp setting and finish with a quick broil.
