| Ingredient | Amount | Notes |

| Large Sweet Potatoes š | 2 whole | Orange-fleshed, firm variety |
| Extra-Virgin Olive Oil š« | 2 tbsp | Light coating for crispiness |

The sweet potatoes are your starālook for firm, vibrant orange-fleshed ones at Waitrose or Tesco, where they keep them in the fresh produce section. Beetsley or Jewel varieties work best. If you can't find them fresh, frozen sweet potato slices (thawed and dried) will do in a pinch. For the paprika, Penzeys or Schwartz have excellent smoked varietiesāworth the splurge for that authentic smoky kick. The cornstarch is non-negotiable for crispiness, so grab a small box if you don't already have it.
No smoked paprika? Regular paprika plus 1/4 tsp liquid smoke gets you close. Swapping the olive oil? Avocado oil works just as wellāboth have high smoke points. Short on cornstarch? Arrowroot powder is a perfect 1:1 substitute. The cayenne is totally optional, but if you're feeling adventurous, Tesco Finest chili flakes add a nice kick. For extra flavor, toss in 1/2 tsp onion powder or 1/4 tsp cinnamonāboth pair beautifully with sweet potatoes.
Store your chips in an airtight container for up to 5 daysāthey'll lose crispiness after that. For longer storage, freeze them in a single layer on parchment before transferring to a bagāup to 3 months. Pro tip: Re-crisp frozen chips at 400Ā°F (200Ā°C) for 3-5 minutes. These chips reheat beautifully, so make a big batch and freeze extras. Perfect for snacking, sharing, or even fancy appetizers!

Step-by-step instructions for crispy sweet potato chips
Here's how to transform humble sweet potatoes into addictive, smoky chips with minimal oil.
š³ Step 1: Prep and Slice the Sweet Potatoes
Start by washing the 2 whole large sweet potatoes thoroughly under cold water to remove any dirt from the skin. Use a vegetable peeler to remove the skin, then slice them into ā -inch thick rounds using a sharp mandoline or knife. For even slices, work quickly and keep the potatoes at room temperature.
Here's the thingāthickness matters. If slices are too thick (Ā¼ inch), they'll turn out chewy. If too thin (ā inch), they'll burn before crisping. Aim for perfect ā -inch slices and pat them dry completely with paper towels. Any moisture left behind will steam the chips instead of crisping them.
šØāš³ Step 2: Create the Flavorful Coating
In a large bowl, whisk together the 2 tablespoons extra-virgin olive oil, 1 tablespoon smoked paprika, 1Ā½ teaspoons sea salt, Ā½ teaspoon ground black pepper, Ā½ teaspoon garlic powder, and Ā¼ teaspoon cayenne pepper (if using). This blend gives you that perfect smoky, slightly spicy kick that makes these chips irresistible.
Add the sliced sweet potato rounds to the bowl and toss gently but thoroughly to coat every piece evenly. I like to use my hands for thisāit helps distribute the seasoning more evenly than a spoon. Let them sit in the bowl for 5 minutes so the flavors really penetrate the sweet potato.
š„ Step 3: Coat with Cornstarch for Extra Crisp
Transfer the seasoned sweet potatoes to a clean baking tray lined with parchment paper. Sprinkle the 1 tablespoon cornstarch evenly over the top and toss again to coat all pieces lightly. The cornstarch creates a crispy exterior that rivals traditional fried chipsāthis is what makes them so satisfyingly crunchy.
Arrange the slices in a single layer, leaving Ā½ inch between each piece. If you're short on space, work in batchesādon't crowd the tray or the chips will steam instead of crisp. This is where patience pays off; proper spacing ensures even cooking and maximum crispiness.
š„ Step 4: Bake Until Perfectly Crispy
Preheat your oven to 220Ā°C (425Ā°F)āthis high temperature is crucial for achieving that perfect crunch. Once preheated, place the tray on the middle rack and bake for 15-20 minutes, flipping the chips halfway through using a fish slice or tongs. You're aiming for golden brown edges and crispy texture.
Watch closely after 15 minutesāovens vary, and you don't want them to burn. They're done when the edges are crispy and the centers still have a slight give (they'll crisp more as they cool). If any pieces brown too quickly, remove them and finish them in a 190Ā°C (375Ā°F) oven for the last few minutes.
ā° Step 5: Cool and Enjoy Immediately
Transfer the crispy sweet potato chips to a wire rack set over a baking sheet to cool for 5-10 minutes. This cooling step is importantāit allows them to crisp up completely and prevents them from becoming soggy from residual steam. Serve them warm for the best texture and flavor.
Here's the magic: these chips taste best right out of the oven when they're still warm and crispy. The smoky paprika flavor really sings when paired with the natural sweetness of the sweet potatoes. Store any leftovers in an airtight container for up to 3 days, but honestly? They won't last that long.
Pro Tips For Making Sweet Potato Chips Recipe Uk
- USE A MANDOLINE, NOT A KNIFE: I learned this the hard wayāslicing sweet potatoes by hand leads to uneven chips that cook at different rates. A mandoline gives you perfectly thin, consistent slices (about 1-2mm) that crisp up evenly. If you donāt have one, a sharp knife works, but take your time and keep your fingers clear of the bladeāthese things have a habit of slipping.
- DRY THE SLICES WELL: Extra-virgin olive oil is your friend here, but only if the sweet potatoes are bone-dry first. Pat each slice with a clean kitchen towel or paper towels to remove all moisture before tossing in the oil. Wet slices steam instead of crisp, and youāll end up with soggy chipsātrust me, Iāve made this mistake more times than Iād like to admit.
- START MEDIUM-HOT, NOT SCORCHING: Cranking the heat to maximum right away might seem like a good idea, but sweet potato chips burn faster than youād think. Start with medium-high heat and let the oil come up to temperature gradually (about 160-170Ā°C). Too hot, and youāll get bitter, burnt edges before the centres crisp. Adjust as neededāthis is where experience kicks in.
- SALT AFTER COOLING: Salting chips straight out of the oil might feel like the right move, but the heat will make the salt melt into the oil, leaving you with a greasy mess. Let the chips cool for just 2-3 minutes on a wire rack, then season with sea salt and smoked paprika. This way, the flavours stick, and you avoid a sticky disasterāyour future self will thank you.
Serving suggestions for sweet potato chips recipe uk
Dip Pairings
Sweet potato chips are incredibly versatileāpair them with a cool, creamy dip to balance their smoky heat. My go-to is hummus (I love Tesco Finest roasted garlic), which adds a smooth, earthy contrast.
For something richer, try whipped feta with a drizzle of honey and Maldon sea salt. The sweetness of the honey complements the natural sweetness of the chips beautifully. šÆ
If you're feeling adventurous, spicy sriracha mayo (mix mayonnaise with 1 tbsp sriracha and a pinch of sugar) adds a tangy kick that cuts through the smokiness. For a British classic, branston pickleāits sweet and tangy flavor profile is perfect for these chips. Just
Sweet Contrasts
Sweet potato chips have a natural sweetness that pairs wonderfully with fruit-based dips. A mango chutney (available at Waitrose) adds a tropical twist, while apple and walnut chutney offers a crunchy texture contrast. For something lighter, blend yogurt with 1 tbsp lemon juice, 1 tsp honey, and a pinch of cardamomāthis bright, floral dip refreshes the palate after each bite. š
Don't overlook caramel or chocolate dips for a decadent touch. Warm dark chocolate (70% cocoa) with a splash of cream and serve it slightly melted for dipping. The contrast of the sweet, smoky chips with the rich chocolate is pure indulgence.
Just be sure to let the chips cool slightly before dipping to avoid melting the chocolate too quickly.
Savory Elevations
For a savory twist, try cheese-based dips like cheddar and chive or goat cheese with herbs. A simple mix of grated mature cheddar, sour cream, and chopped chives creates a creamy, tangy dip that pairs perfectly.
If you're hosting, warm spinach and artichoke dip (baked with cream cheese and parmesan) adds a hearty, satisfying element. š§
For a lighter option, avocado and lime dip (mashed avocado, lime juice, salt, and a touch of garlic) brings a refreshing, creamy texture. This dip works especially well if you've added a bit of heat to your chipsāit cools things down beautifully.
Serve it chilled for the best flavor and texture.
Presentation Tips
When serving sweet potato chips, presentation mattersāthey look just as good as they taste! Arrange them on a wooden board or slate platter for a rustic touch, and scatter fresh parsley or microgreens on top for a pop of color.
For a more elegant look, use a white ceramic bowl and serve the chips in a pile with dips in small ramekins. š½ļø
If you're making these for a party, consider flavor-station setups. Set out small bowls of different seasonings (like smoked paprika, garlic powder, or chili flakes) and let guests customize their own chips.
This interactive approach makes snacking fun and lets everyone tailor their flavor to their taste. Just be sure to have extra chips on handāpeople will go through them quickly!

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
Regular potatoes won't workāthey lack the natural sweetness and moisture balance needed for crispy chips. Sweet potatoes have a higher sugar content and drier texture that creates that perfect caramelized crisp. If you're desperate, try purple sweet potatoes for a fun color twist, but stick with orange-fleshed for best results.
Why did my chips turn out soggy instead of crispy?
Soggy chips usually mean one of three things: slices were too thick (Ā¼ inch instead of ā inch), they weren't dried properly, or they were crowded on the tray. Always pat slices completely dry with paper towels and arrange them with Ā½ inch space between. For extra insurance, bake at 220Ā°C (425Ā°F) for 15-20 minutesāhigh heat is key for crispiness.
What's the best oil for air frying these chips?
For air frying, use avocado oil or light olive oilāboth have high smoke points and won't burn at 200Ā°C (400Ā°F). Lightly brush the slices with oil after seasoning (don't soak them). Air fry in batches for 8-10 minutes, shaking the basket every 3-4 minutes for even cooking. The cornstarch coating works just as well in an air fryer as in the oven.
How do I make these chips spicier?
For extra heat, increase the cayenne to Ā½ teaspoon or add 1 teaspoon chili powder to the seasoning mix. For a smoky kick, swap some salt for 1 teaspoon smoked sea salt. Pro tip: Toss finished chips with Tesco Finest chili flakes before serving. If you love heat, try a honey-sriracha glaze (mix 1 tbsp honey with 1 tbsp sriracha) after baking.
Can I make these chips ahead of time?
Yes! Bake them up to 2 days ahead and store in an airtight container at room temperature. For longer storage, freeze them in a single layer on parchment before transferring to a bag (up to 3 months). To revive, bake at 200Ā°C (400Ā°F) for 3-5 minutes until crispy again. The flavor actually improves after 24 hours as the spices meld.
