Ingredients for sweet potato peel
Pantry staples meet sweet potato scraps for crispy, golden bites with perfect sweet-spicy crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 large | Organic preferred, peeled |
| Dijon Mustard 🍯 | 2 tbsp | High-quality, tangy |
| Cornstarch 🌾 | ½ cup | For crispy texture |
| Brown Sugar 🍚 | 1 tbsp | Light or dark |
| Ground Cinnamon 🌿 | 1 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Flaky sea salt for finish |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| Olive Oil 🫒 | 1 tbsp | For tossing |
| Honey 🍯 | 1 tbsp | For drizzling (optional) |
Sweet potatoes are the star—organic or conventional works, but organic has fewer pesticides. Grab the orange-fleshed ones (not purple sweet potatoes) since they're sweeter. Peel them first, then slice into even strips about 1/8-inch thick. Whole Foods or Trader Joe's usually have the best selection. If you're using leftover peels, pat them very dry with a paper towel—moisture kills crispiness. I always keep a bag of peels in the freezer for quick snacks later.
No Dijon mustard? Yellow mustard at half the amount works in a pinch. Cornstarch is non-negotiable here—it's what creates that addictive crunch. Bob's Red Mill is my go-to brand, but any cornstarch will do. For the spices, cinnamon should be fresh—it loses flavor fast. Penzeys or bulk bins have the best quality. Black pepper? Freshly cracked is ideal, but pre-ground is fine if it's in a sealed container. The olive oil just helps the coating stick—any light oil works, even avocado oil.
These keep for 3 days in an airtight container at room temperature, but they're best fresh out of the oven. For extra crunch, reheat at 400°F for 5-7 minutes. Store in a single layer so they don't steam and get soggy. I always make double—freeze extras in a single layer, then transfer to a bag. Reheat frozen peels straight from the freezer for 8-10 minutes at 400°F. Trust me, they're even better the second time around.

Step-by-step instructions for crispy mustard-crusted sweet potato peels
Here's how to transform humble peels into irresistible, crunchy bites with a perfect sweet-spicy balance.
👨🍳 Step 1: Prep and Slice the Sweet Potato Peels
Peel the 2 large sweet potatoes using a vegetable peeler, working in one continuous motion to create long, even strips about ¼-inch wide. I like to keep them whole lengthwise—this creates more surface area for crisping. As you peel, cut off any thick or uneven spots to maintain consistency.
Rinse the peels under cold water to remove any excess starch, then pat them completely dry with paper towels. Moisture is the enemy of crispiness, so take your time here. The drier they are, the better they'll brown and crisp in the oven. Spread them on a clean kitchen towel and let them air-dry for 5 minutes while you prepare the seasoning.
🍳 Step 2: Create the Mustard-Cinnamon Coating
In a medium bowl, whisk together the 2 tbsp Dijon mustard, 0.5 cup cornstarch, 1 tbsp brown sugar, 1 tsp ground cinnamon, 0.5 tsp salt, and 0.25 tsp black pepper until completely combined. The mixture should look like a thick, grainy paste—this will create that perfect crunchy crust.
Add the dried sweet potato peels to the bowl and toss gently but thoroughly to coat every strip evenly. I like to use my hands for this part—it helps distribute the coating more evenly than a spoon. The peels should look uniformly dusted with the spiced mustard mixture. If they seem too dry, add 1 teaspoon of olive oil to help the coating stick.
🔥 Step 3: Bake Until Golden and Crispy
Preheat your oven to 425°F and line a large baking sheet with parchment paper. Arrange the coated peels in a single layer, leaving about ½-inch between each piece. They'll expand as they bake, so don't crowd them or they'll steam instead of crisp.
Bake for 12-15 minutes, flipping the peels halfway through with a spatula, until they're deep golden brown and crispy. You're aiming for that perfect balance between tender inside and crispy outside. The edges should look slightly charred in spots—that's where all the flavor hides. If they're browning too quickly, reduce the oven temperature to 400°F for the second half of baking.
🍯 Step 4: Finish with Honey and Serve Warm
Remove the peels from the oven and immediately drizzle with the 1 tbsp honey, tossing gently to coat. The honey will caramelize slightly from the residual heat, adding a beautiful gloss and subtle sweetness that balances the mustard's tang. Sprinkle with a pinch of flaky sea salt for extra depth.
Let them cool for 2-3 minutes before serving—this gives the honey time to set slightly and prevents a sticky mess. Serve warm as a snack, side dish, or even a topping for yogurt or ice cream. The contrast of crispy, spicy-sweet peels with creamy textures is pure magic. Store any leftovers in an airtight container for up to 3 days, though they're best enjoyed fresh while crispy.
Pro Tips For Making Sweet Potato Peel
- USE PEELS FROM FRESH POTATOES: Peels from week-old sweet potatoes taste bland—pick ones with vibrant orange skin and no soft spots. Scrub them clean but leave the skin intact; the texture and flavor are tied to that crisp outer layer.
- COAT PEELS IN DRY CORNSTARCH: Toss the peels in cornstarch before hitting them with the mustard-sugar mix—this creates a lighter, crispier crust. Skip the wet step, or they’ll turn soggy instead of golden.
- BAKE AT 400°F—NOT HIGHER: I learned this the hard way: 425°F burns the edges before the centers crisp. Stick to 400°F for even browning, and flip halfway if they’re overlapping—crowding steams instead of crisps.
- LESS MUSTARD, MORE CRISPY: That Dijon mustard is sticky—use just 1 tablespoon for a batch of peels, or they’ll clump and steam. Spread them on a single layer, and they’ll turn into shatteringly crisp chips instead of gluey clumps.
Storing and reheating your leftovers
Room Temperature Storage
These crispy peels stay fresh at room temperature for 3 days when stored in an airtight container—I use glass jars with tight-sealing lids. The key is keeping them in a single layer to prevent moisture buildup that turns them soggy.
I like to store them in the original baking tray lined with parchment paper for the first 24 hours, then transfer to a container afterward. 🌟
Freezer Preservation
For longer storage, freeze peels in a single layer on a baking sheet for 1 hour to prevent sticking, then transfer to a freezer bag with excess air squeezed out. They’ll keep for up to 3 months—just reheat straight from frozen at 400°F for 8-10 minutes.
The second time around, they’re even crispier because the starches re-crystallize during freezing. 🥶
Reheating for Maximum Crunch
To revive crispiness, spread cooled peels on a baking sheet and bake at 400°F for 5-7 minutes—no oil needed! For stovetop reheating, use a dry skillet over medium heat for 2-3 minutes, stirring constantly.
Microwaving works in a pinch (30-second bursts), but expect slightly softer results. Always reheat until steaming hot to kill any bacteria. 🔥
Reviving Soggy Peels
If peels lose crispiness, toss them in 1 tsp cornstarch and reheat at 425°F for 3-4 minutes. The cornstarch acts like a fresh coating, restoring that addictive crunch. For extra help, sprinkle with a pinch of baking powder before reheating—the alkaline nature helps crisp them up faster. 💡
Portioning for Snacking
Divide peels into small snack-sized portions (about ¼ cup each) before storing to make grab-and-go snacking effortless. Store portions in small mason jars or reusable containers—perfect for lunchboxes or office snacks.
Label with the date to track freshness. I keep a jar in my desk drawer for quick energy boosts. ✨

Frequently asked questions about sweet potato peel bites
Can I use purple sweet potatoes for this recipe?
While purple sweet potatoes work, they have a more earthy flavor and may not caramelize as beautifully. The orange-fleshed varieties (like Beauregard) are ideal—they're sweeter and develop that perfect golden-brown crust. If you must use purple, reduce the brown sugar to ½ tbsp to avoid overpowering the flavor.
What if my oven runs hot and burns the peels?
Lower the oven temperature to 400°F for the second half of baking and check them at 10 minutes. If they're browning too quickly, spread them out more or use a dark baking sheet (it absorbs more heat). A wire rack over a baking sheet also helps with even cooking.
Are these peels gluten-free?
Yes! This recipe is naturally gluten-free since it uses cornstarch instead of flour. Just ensure your Dijon mustard is certified gluten-free (some brands contain wheat). The spices and honey are also typically gluten-free, but always double-check labels.
Can I make these with regular potatoes?
Regular potatoes won't work—they lack the natural sweetness and moisture that makes sweet potato peels crispy. The starch content is different, and they'll turn out dense rather than crispy. Stick with sweet potatoes for the best texture and flavor.
How can I make them spicier?
Add ½ tsp cayenne pepper or 1 tsp smoked paprika to the coating for heat. For extra kick, toss the baked peels with a pinch of chili powder or a sprinkle of hot sauce before serving. Just remember—more spice means less room for the honey's sweetness!
