Ingredients
For these sweet potato coins I rely on fresh, high‑quality sweet potatoes and a few pantry basics that together create a sweet‑savory glaze. The brown butter adds a nutty depth, while maple syrup supplies natural sweetness. A dash of smoked paprika and sea salt gives the perfect balance of smoky heat and seasoning. Finishing with fresh thyme adds a fragrant, herbaceous lift that brightens the dish.
Main Ingredients
- 2 large sweet potatoes (about 1½ lb)
- 2 Tbsp unsalted butter
- 1 Tbsp pure maple syrup
Seasonings
- ½ tsp smoked paprika
- ½ tsp ground cumin
- ¼ tsp freshly ground black pepper
- ¾ tsp sea salt (plus extra for finishing)
Fresh Herbs & Finish
- 1 Tbsp fresh thyme leaves, chopped
- Optional: pinch of red‑pepper flakes for heat
The sweet potatoes provide a naturally sweet base, while the butter‑maple glaze adds a glossy, caramelized coating that adheres to every coin. Smoked paprika and cumin lend a subtle earthiness, and the sea salt amplifies the flavors without overwhelming sweetness. Fresh thyme finishes the dish with a bright, aromatic note that elevates the overall profile, making these coins a standout brunch item.
Step-by-Step Instructions
Preparing the Sweet Potatoes
Begin by peeling the sweet potatoes and slicing them into uniform ¼‑inch thick rounds. Stack a few rounds and use a sharp chef’s knife to cut each round into ½‑inch wide “coins.” Uniform thickness ensures even cooking; if some pieces are thicker, they may end up soft in the center while the thinner ones become too crisp.
Coating the Coins
- Brown the Butter. Place a medium saucepan over medium heat, add 2 Tbsp unsalted butter, and let it melt. Continue cooking, swirling the pan, until the butter turns a deep golden color and releases a nutty aroma—about 3‑4 minutes. This step builds a rich flavor foundation for the glaze.
- Mix the Glaze. Reduce the heat to low and whisk in 1 Tbsp pure maple syrup, ½ tsp smoked paprika, ½ tsp ground cumin, ¼ tsp black pepper, and ¾ tsp sea salt. The mixture should become glossy and slightly thickened, coating the back of a spoon.
- Toss the Coins. Transfer the sliced sweet potatoes to a large mixing bowl. Pour the warm glaze over them and toss gently until each coin is evenly coated. The butter helps the glaze cling, while the spices adhere to the surface.
Roasting
- Preheat the Oven. Set your oven to 425°F (220°C) and line a large rimmed baking sheet with parchment paper. A hot oven creates the initial burst of caramelization needed for crisp edges.
- Arrange the Coins. Spread the coated sweet potato coins in a single layer, leaving a small gap between each piece. Overcrowding traps steam and prevents the desired crunch.
- Bake Until Golden. Roast for 20‑25 minutes, flipping halfway through. Look for a deep amber color and crisp edges; the centers should be tender when pierced with a fork. If some pieces brown faster, rotate the pan for even results.
- Finish with Herbs. Remove the pan from the oven, sprinkle 1 Tbsp fresh thyme leaves and an extra pinch of sea salt over the hot coins. The residual heat releases the herb’s aroma, adding a fresh finish.
Serving
Transfer the crispy coins to a serving platter while still warm. They’re perfect as a stand‑alone brunch bite, a side for scrambled eggs, or a topping for avocado toast. For an extra pop, drizzle a tiny drizzle of additional maple syrup or a squeeze of fresh lemon juice just before serving.
Tips & Tricks
Perfecting the Recipe
Uniform Slices. Use a mandoline or a sharp chef’s knife to achieve consistent thickness; this guarantees every coin crisps at the same rate.
Dry the Potatoes. After washing, pat the slices dry with a kitchen towel. Excess moisture creates steam, which softens the coating instead of crisping it.
Don’t Skip the Flip. Turning the coins halfway through roasting ensures both sides develop that coveted caramelized crust.
Use a Light Hand with Salt. A modest amount of sea salt highlights sweetness without making the dish overly salty.
Flavor Enhancements
Add a splash of fresh orange juice to the glaze for citrus brightness, or stir in a teaspoon of grated ginger for a warm, spicy undertone. A pinch of smoked sea salt can intensify the smoky paprika flavor, while a drizzle of tahini after roasting adds a creamy, nutty contrast.
Common Mistakes to Avoid
Avoid using too much oil; the butter‑maple glaze already provides enough fat for crisping. Also, don’t bake on a cold sheet—preheated parchment ensures immediate contact heat, which is essential for a crunchy exterior.
Pro Tips
Finish Under the Broiler. For an extra snap, switch to broil for the final 2‑3 minutes, watching closely to prevent burning.
Season While Hot. Sprinkle the final pinch of sea salt and fresh thyme immediately after removing from the oven; the heat releases aromatic oils.
Batch Cook. The coins keep their texture well when cooled on a wire rack; reheat briefly in a hot oven to revive crispness.
Use a Light Coating. Too much glaze can make the coins soggy; a thin, even layer is all you need for flavor and crunch.
Variations
Ingredient Swaps
Swap sweet potatoes for carrots or parsnips for a different earthy sweetness. Replace maple syrup with agave nectar or a drizzle of honey for a subtle flavor shift. For a smoky kick, exchange smoked paprika for chipotle powder, or add a tablespoon of grated Parmesan during the last minutes of roasting.
Dietary Adjustments
To keep the dish vegan, substitute butter with coconut oil and ensure the sweetener is plant‑based. Gluten‑free is automatic, as no grains are used. For a keto‑friendly version, reduce the maple syrup to a sugar‑free alternative like erythritol‑based syrup and serve with avocado or a side of scrambled eggs.
Serving Suggestions
Pair the coins with poached eggs and a dollop of Greek yogurt for a protein‑rich brunch. They also shine as a topping for grain bowls, tossed with quinoa, roasted veggies, and a drizzle of tahini. For a sweet‑savory twist, serve them alongside a fresh berry compote.
Storage Info
Leftover Storage
Allow the sweet potato coins to cool completely, then transfer them to an airtight container. Store in the refrigerator for up to 4 days. For longer keeping, spread the coins on a freezer‑safe tray, freeze solid, and then bag them; they’ll maintain quality for up to 3 months.
Reheating Instructions
Reheat in a preheated 350°F (175°C) oven on a wire rack for 10‑12 minutes, or until the edges regain their crispness. Microwaving works in a pinch—cover a single serving with a damp paper towel and heat for 45‑60 seconds, then finish under the broiler for a quick crunch boost.
