Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 200°C (fan 180°C). Line two large baking sheets with parchment paper – one for the sweet potato fries and one for the cheese twists.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>For the sweet potato fries: Scrub the sweet potatoes thoroughly but leave the skin on for extra fiber and texture. Cut them into evenly sized sticks about 1cm thick. Try to keep them uniform in size so they cook at the same rate – this is crucial for achieving fries that are crispy outside and tender inside.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Place the sweet potato sticks in a large bowl and soak in cold water for 10 minutes. This removes excess starch and helps them crisp up during baking. After soaking, drain thoroughly and pat completely dry with kitchen towels – moisture is the enemy of crispiness!</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Return the dried sweet potato sticks to a clean bowl. Sprinkle over the cornstarch and toss until lightly coated. The cornstarch creates a thin layer that helps achieve a crispier exterior. Then add the olive oil, paprika, garlic powder, dried thyme, salt, and pepper. Toss until evenly coated.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Arrange the sweet potato fries in a single layer on one of the prepared baking sheets, ensuring they don't touch each other. Overcrowding will cause them to steam rather than crisp. Place in the preheated oven.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>While the sweet potatoes begin baking, prepare the cheese twists. Unroll the puff pastry sheet on a lightly floured surface, keeping it on its parchment if it comes with it. The cold pastry is easier to work with and will produce flakier results, so don't let it warm up too much.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>In a small bowl, mix together the grated cheddar, Parmesan, dried oregano, and cayenne pepper (if using). Brush the puff pastry lightly with beaten egg, then sprinkle the cheese mixture evenly over half of the pastry sheet, leaving a 1cm border around the edges.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Fold the uncovered half of the pastry over the cheese-covered half and press down gently to seal. The egg wash acts as a glue here. Use a rolling pin to lightly roll over the top, which helps the cheese adhere to the pastry layers.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Using a sharp knife, cut the pastry into approximately 2cm wide strips. Take each strip and twist it several times, holding both ends and spinning in opposite directions. Place the twisted strips on the second prepared baking sheet, leaving space between them as they will expand during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Brush the cheese twists with the remaining beaten egg and sprinkle with flaky sea salt. The egg wash gives them a beautiful golden color as they bake, while the salt enhances the savory flavors.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Check on the sweet potato fries (they should have been baking for about 15 minutes now). Carefully flip them over using a spatula and return to the oven. Place the cheese twists in the oven at the same time.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Bake the cheese twists for 12-15 minutes until puffed and golden brown. The high fat content in the butter of the puff pastry creates steam during baking, which separates the layers and creates that beautiful flaky texture. Remove when done and place on a wire rack to cool slightly.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Continue baking the sweet potato fries for an additional 5-10 minutes until they're crispy on the outside and tender inside. They should have caramelized edges due to the natural sugars in the sweet potatoes. Total baking time for the fries will be around 30-35 minutes.</li><li class="MethodStepper"><h4 class="step-title">Step 14</h4>For maximum crispiness, once you remove the sweet potato fries from the oven, let them rest on the baking sheet for 5 minutes before serving. This allows excess steam to escape and the exterior to set up properly.</li><li class="MethodStepper"><h4 class="step-title">Step 15</h4>Serve both the sweet potato fries and cheese twists warm. They complement each other wonderfully – the sweet, earthy fries balancing the rich, savory cheese twists. Enjoy as is or with your favorite dipping sauce!</li></ol>

FAQs

Find answers to your most pressing questions about this delicious recipe right here.

What ingredients are used in Baked Sweet Potato Fries & Cheese Twists?

The recipe uses sweet potatoes, olive oil, spices (paprika, garlic powder, thyme), cornstarch, ready-rolled puff pastry, cheddar and Parmesan cheeses, oregano, cayenne pepper (optional), egg, and sea salt. These ingredients create crispy fries and flaky, cheesy pastry twists.

How to cook Baked Sweet Potato Fries & Cheese Twists at home?

Learn how to cook Baked Sweet Potato Fries & Cheese Twists by preheating your oven to 200°C, cutting sweet potatoes into even sticks, soaking them to remove starch, coating with cornstarch and seasonings, and baking until crispy. Meanwhile, layer cheese on puff pastry, cut into strips, twist, and bake until golden. The result is a perfect appetizer duo that's healthier than fried versions.

How do I make sweet potato fries actually crispy in the oven?

For truly crispy sweet potato fries, soak them in cold water to remove excess starch, dry thoroughly, coat lightly with cornstarch before adding oil and seasonings, arrange in a single layer without overcrowding, and bake at a high temperature (200°C). Flipping halfway through baking is also essential.

What's the best cheese to use for puff pastry twists?

The best cheeses for puff pastry twists combine a melty variety with a flavourful hard cheese - mature cheddar or Gruyère paired with Parmesan works brilliantly. These create the perfect balance of stretch, flavour and golden colour when baked. Avoid very soft cheeses as they can make the pastry soggy.

Can I prepare these appetizers ahead of a party?

Yes! The cheese twists can be prepared completely ahead and reheated briefly before serving. For the sweet potato fries, you can cut and season them in advance, but for maximum crispiness, it's best to bake them just before serving. Both items can be kept warm on low heat in the oven.
