Ingredients for sweet potato chips recipe uk
UK pantry essentials transformed into restaurant-worthy chips with smoky depth and perfect crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Firm, uniform size preferred |
| Smoked Paprika 🌶️ | 2 tbsp | High-quality for smoky depth |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked for sharpness |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Olive Oil 🫒 | 2 tbsp | Light, neutral flavor |
| Garlic Powder 🧄 | ½ tsp | For subtle savory note |
| Baking Powder 🍞 | ¼ tsp | For extra crispiness |
| Cornflour 🌾 | 2 tbsp | UK standard for coating |
The sweet potatoes are the star—opt for firm, uniform varieties like Beurre or Jewel for even cooking. UK supermarkets like Tesco or Sainsbury's stock these reliably. Look for skins free of blemishes and avoid any with soft spots. Pre-cut sweet potatoes lose moisture fast, so slice them just before baking. For the paprika, Schwartz or Garryowen brands deliver that authentic smoky flavor—avoid the cheap own-brand versions that taste like dust.
No smoked paprika? Substitute half the amount with regular paprika plus a pinch of liquid smoke for depth. Running low on cornflour? All-purpose flour works in a pinch, though it may yield slightly less crisp chips. The olive oil matters here—use a light, neutral variety like Rapeseed or Sunflower to avoid overpowering the sweet potato flavor. For extra crunch, add 1 tbsp rice flour to the cornflour mix. And if you're feeling adventurous, a dash of cayenne adds subtle heat without overpowering the smoky sweetness.
Pre-sliced sweet potatoes keep for 3 days in the fridge, wrapped tightly in damp paper towels. The seasoning mix stays potent for 3 months in an airtight container. For best results, bake immediately after slicing—waiting even 30 minutes can make the chips soggy. These chips reheat beautifully in the oven at 180°C (350°F) for 5 minutes, though they're best enjoyed fresh. Store leftovers in a sealed metal container to maintain crispness.

Step-by-step instructions for perfect sweet potato chips
Here's how to transform humble sweet potatoes into restaurant-quality chips with a smoky crunch.
🔪 Step 1: Slice Sweet Potatoes Paper-Thin
Peel the 2 whole large sweet potatoes and cut them into ⅛-inch thick slices using a sharp mandoline or knife. Uniform thickness is critical—thinner slices crisp faster, but too thin and they burn. I like to cut them lengthwise first, then slice crosswise for consistent strips.
Soak the slices in cold water for 10 minutes to remove excess starch, which prevents crispiness. Drain thoroughly and pat completely dry with paper towels. Any moisture left behind will steam the chips instead of crisping them. This step makes all the difference for that satisfying crunch.
👨🍳 Step 2: Create the Seasoned Coating
In a large bowl, whisk together the 2 tbsp cornflour, 2 tbsp smoked paprika, 1.5 tsp kosher salt, 1 tsp ground black pepper, 0.5 tsp garlic powder, and 0.25 tsp baking powder. The baking powder adds an extra lift that makes these chips irresistibly crispy. I like to press the spices into the cornflour with my fingers to break up any lumps.
Add the dry sweet potato slices and toss gently until evenly coated. Don't overmix or the slices will tear. For extra adhesion, I like to place the bowl in the freezer for 5 minutes—this firms up the cornflour coating so it sticks better during frying.
🔥 Step 3: Fry in Small Batches for Even Crisping
Heat 2 tbsp olive oil in a heavy-bottomed skillet over medium-high heat until it reaches 325°F (use a thermometer for accuracy). Add 4-5 slices at a time—overcrowding lowers the oil temperature and steams the chips instead of frying them. Fry for 2-3 minutes per side until edges are golden brown and crispy.
Watch carefully as they cook—they'll crisp in seconds once they reach the right temperature. Remove with a slotted spoon and drain on paper towels. The oil should remain around 325°F throughout cooking. If it drops below 300°F, the chips will absorb oil instead of crisping.
⏰ Step 4: Rest and Serve Immediately
Transfer the fried chips to a wire rack set over a baking sheet for 5 minutes to cool slightly. This resting period allows the cornflour coating to set properly, preventing a soggy texture. Serve immediately while still crispy—these chips lose their crunch within minutes.
For maximum flavor, I like to sprinkle with an extra pinch of smoked paprika right before serving. The contrast of warm, smoky chips with cool dips like sour cream or spicy mayo makes them irresistible. Store any leftovers in an airtight container for 1 day, but they won't be as crispy.
Pro Tips For Making Sweet Potato Chips Recipe Uk
- Slice Thin, Stack Tidy: I learned this the hard way—uneven slices mean uneven cooking. Use a sharp mandoline (or a steady hand with a knife) and stack slices in a single layer, no overlapping. That way, they crisp up evenly instead of turning to mush in the middle while the edges burn.
- Salt Before Frying: Don’t wait until the end—sprinkle kosher salt right after slicing and let them sit for 10 minutes. This draws out excess moisture so your chips crisp up faster and don’t steam in the oil. (Yes, even if you’re impatient like me.)
- Watch the Oil Temp: Too hot, and they’ll burn before crisping. Too cool, and you’ll end up with sad, greasy chips. Test with a small slice—if it sizzles loudly and turns golden in 1-2 minutes, you’re golden. Aim for around 170°C (340°F) if your thermometer’s handy.
- Double-Crisp in Two Batches: Smoked paprika’s great, but it can make chips stick if the oil’s not hot enough. Fry half first, drain on a wire rack (not paper towels—this keeps them crisp), then season with the rest of the spice after they’ve cooled slightly. The second batch will thank you.

Frequently asked questions
Can I use regular flour instead of cornflour?
You can substitute all-purpose flour, but the texture won't be quite the same. Cornflour creates a lighter, crispier coating that's perfect for these chips. If you must use flour, add 1 extra tbsp to compensate for its heavier texture, and expect slightly thicker chips. For best results, use 100% cornflour as called for in the recipe.
How do I make these without frying?
For an oven-baked version, preheat to 200°C (400°F) and toss the seasoned slices with 1 tbsp olive oil. Spread in a single layer on a baking tray lined with parchment and bake for 15-20 minutes, flipping halfway. The oven method yields slightly softer chips but still delicious. For extra crispiness, bake at 220°C (425°F) for 10 minutes.
Why did my chips turn out soggy?
Soggy chips usually mean excess moisture wasn't removed properly. Double-check that you pat the slices completely dry after soaking and draining. Also, ensure your oil is at the correct temperature—too cool (300°F) causes steaming instead of frying. For oven versions, avoid overcrowding the tray and bake at a higher temperature (220°C/425°F) for better crispiness.
What's the best way to store leftovers?
Store in an airtight container at room temperature for 1 day maximum. For longer storage, freeze between layers of parchment paper for up to 1 month. Reheat oven-baked chips at 180°C (350°F) for 5 minutes to restore some crispness. Note: Fried chips lose crispness faster than oven-baked ones.
Can I add cheese to these chips?
For a cheesy version, sprinkle 2 tbsp grated cheddar or 1 tbsp cream cheese between the cornflour coating and sweet potato slices. The cheese melts slightly during frying, creating a delicious gooey center. Try Welsh cheddar for a UK twist—it melts beautifully and adds a tangy flavor that pairs perfectly with the smoky paprika.
