Ingredients
The foundation of this recipe is the sweet potato itself – a nutrient‑dense root vegetable that crisps beautifully when thinly sliced. A light coating of corn starch and a blend of smoky, sweet, and mildly spicy seasonings create the signature crunch. The finishing glaze of maple, mustard, and apple‑cider vinegar adds a glossy, tangy sweetness that elevates the humble coin into a star‑worthy bite.
Main Ingredients
- 2 large sweet potatoes (about 1½ lb)
- 2 tablespoons olive oil
- 2 tablespoons cornstarch
Seasoning Blend
- 1 teaspoon smoked paprika
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon sea salt
- ¼ teaspoon freshly ground black pepper
Maple‑Mustard Glaze
- 2 tablespoons pure maple syrup
- 1 tablespoon Dijon mustard
- 1 teaspoon apple cider vinegar
- ¼ teaspoon cayenne pepper (optional)
Garnish
- Fresh thyme leaves
- Chopped parsley (optional)
Each component plays a purpose: the olive oil binds the cornstarch and seasonings, ensuring an even crust; the smoked paprika and garlic powder infuse depth; the maple‑mustard glaze adds a sweet‑tangy finish that caramelizes during roasting. Fresh herbs added after baking bring a burst of brightness that balances the richness, making every bite lively and satisfying.
Step-by-Step Instructions
Preparing the Sweet Potatoes
Begin by washing the sweet potatoes thoroughly, then slice them into uniform ¼‑inch coins using a mandoline or a sharp knife. Uniform thickness guarantees even cooking; thinner slices crisp faster, while thicker ones stay soft inside. Pat the slices dry with a clean kitchen towel—removing excess moisture is essential for a golden crust.
Seasoning & Coating
- Oil & Toss. In a large bowl combine the sweet‑potato coins with 2 tablespoons olive oil. Toss until each piece is lightly coated; the oil helps the cornstarch adhere and promotes browning.
- Add Cornstarch. Sprinkle 2 tablespoons cornstarch over the oiled slices. Toss again until a thin, matte powder covers every coin—this creates the signature crunch once baked.
- Season. Mix the smoked paprika, garlic powder, onion powder, salt, and pepper in a small bowl, then sprinkle over the coated potatoes. The spices cling to the starch, ensuring flavor is locked into the crust.
- Arrange on Sheet. Spread the seasoned coins in a single layer on a parchment‑lined baking sheet. Overcrowding leads to steaming, so use two sheets if necessary to keep each piece exposed to hot air.
Baking & Finishing
- Roast. Preheat the oven to 425°F (220°C). Bake the sweet‑potato coins for 15 minutes, then flip each piece with a spatula and continue roasting another 10‑12 minutes until edges are deep golden and the centers are fork‑tender.
- Glaze. While the potatoes finish, whisk together the maple syrup, Dijon mustard, apple cider vinegar, and cayenne pepper in a small saucepan. Simmer for 2‑3 minutes until slightly thickened.
- Coat. Remove the pan from the oven and drizzle the warm glaze over the hot coins, tossing gently to ensure an even shine. The residual heat caramelizes the glaze, creating a glossy finish.
- Garnish & Serve. Sprinkle fresh thyme leaves and, if desired, chopped parsley over the top. Serve immediately while the crust is still crisp, paired with eggs, avocado toast, or a dollop of Greek yogurt for a complete brunch.
Tips & Tricks
Perfecting the Recipe
Uniform Slices. Use a mandoline to achieve consistent ¼‑inch thickness; this prevents some coins from being soggy while others burn.
Dry Thoroughly. Pat the slices completely dry before oiling; excess moisture creates steam and reduces crispness.
Single Layer. Arrange coins without overlap; air can circulate, giving each piece a uniform golden edge.
Mid‑Bake Flip. Flipping halfway ensures both sides receive equal heat, promoting an even crunch.
Flavor Enhancements
Add a splash of fresh lemon juice to the glaze for bright acidity, or stir in a pinch of smoked chipotle powder for deeper smoky heat. A drizzle of melted ghee instead of olive oil before baking yields an even richer, buttery crust.
Common Mistakes to Avoid
Skipping the cornstarch will result in soggy coins, and using too much oil can make them greasy rather than crisp. Also, avoid opening the oven door too often; each opening drops temperature and can prevent the desired caramelization.
Pro Tips
Pre‑heat the Baking Sheet. Place the parchment‑lined sheet in the oven while it preheats; the hot surface jump‑starts the crisping process.
Use a Wire Rack. For maximum air flow, set the coins on a wire rack over the sheet; this eliminates the need to flip and yields an ultra‑crisp bottom.
Finish with a Pinch of Sea Salt. A light sprinkle just before serving amplifies the sweet‑savory contrast.
Serve Immediately. The coins are at their crispiest within the first 10 minutes; if they sit too long they soften.
Variations
Ingredient Swaps
Replace sweet potatoes with thinly sliced carrots or parsnips for a different root‑vegetable flavor. For a sweeter twist, drizzle a little honey over the glaze before serving. If you prefer a savory profile, swap the maple syrup for a tablespoon of soy sauce and add toasted sesame seeds after baking.
Dietary Adjustments
This recipe is naturally gluten‑free. To make it vegan, use a plant‑based oil such as avocado oil and ensure the maple syrup is pure (no added honey). For a low‑carb version, cut the maple syrup in half and replace the remaining sweetness with a sugar‑free maple‑flavored syrup.
Serving Suggestions
Pair the coins with poached eggs and a drizzle of sriracha for a spicy brunch, or serve alongside smoked salmon and cream cheese for an elegant appetizer. They also make a crunchy topping for soups and stews, adding texture and a hint of sweetness.
Storage Info
Leftover Storage
Allow the coins to cool completely, then transfer them to an airtight container. Store in the refrigerator for up to 3 days. For longer keeping, portion them into freezer‑safe bags, remove excess air, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating Instructions
Reheat on a preheated 350°F (175°C) sheet pan for 8‑10 minutes, or until crisp and hot throughout. For a quicker method, spread a single layer on a microwave‑safe plate, cover loosely, and heat on medium power for 1‑2 minutes, then finish under the broiler for 2 minutes to restore crunch.
