To get the best flavor, I took a morning stroll down to Roots, Fruits & Flowers in the West End to pick up the freshest organic sweet potatoes. The real secret to the crunch, however, is the cookware. I am cooking these in my heavy-duty Lodge Cast Iron Skillet (a brilliant find from John Lewis in the city centre). Cast iron retains heat beautifully, ensuring an even, professional-grade sear without needing excessive oil.
The Ingredients
- 2 large Organic sweet potatoes, peeled
- 1 large Scottish free-range egg (acts as our binder)
- 2 tbsp Cornflour (the secret to keeping them structurally sound and extra crispy)
- 1 tsp Smoked paprika
- 1/2 tsp Garlic powder
- 1/4 tsp Sea salt and freshly cracked black pepper
- 2 tbsp Cold-pressed Scottish Rapeseed Oil (like Mackintosh of Glendaveny) for a healthy, high-smoke-point fry.
The Chef's Method
- The Crucial Squeeze: Grate the peeled sweet potatoes using the large holes of a box grater. Chef's Secret: Transfer the grated potato onto a clean kitchen towel, roll it up, and aggressively wring out as much liquid as humanly possible over the sink. Moisture is the enemy of crispiness! If your potatoes are wet, they will steam instead of fry.
- The Mix: Transfer the dry, grated sweet potato into a large mixing bowl. Add the egg, cornflour, smoked paprika, garlic powder, salt, and pepper. Use a fork to toss everything together until the potato shreds are evenly coated.
- The Cast Iron Sear: Place your cast iron skillet over medium-high heat. Let it get properly hot before adding the rapeseed oil.
- The Fry: Drop a generous spoonful of the sweet potato mixture into the hot oil. Use the back of a spatula to press it down flat—the thinner they are, the crispier they get.
- Golden Perfection: Fry undisturbed for 4–5 minutes until the bottom is a deep, caramelized golden brown. Carefully flip and cook for another 4 minutes on the other side.
- Drain and Serve: Transfer the hash browns to a wire rack or a paper towel-lined plate to drain any excess oil before serving immediately.
Culinary Notes & Variations
The Vegan Swap: If you are cooking plant-based, simply swap the free-range egg for a "flax egg" (1 tablespoon of ground flaxseed whisked with 3 tablespoons of water, left to sit for 5 minutes).
Flavor Pairings: The earthy sweetness of the potato begs for a savory, acidic contrast. I highly recommend topping these hash browns with a perfectly poached egg, a smash of fresh avocado with lime juice, and a light drizzle of hot honey or sriracha.
Meal Prep Tip: You can grate and squeeze the sweet potatoes the night before! Store the dry shreds in an airtight container in the fridge, and you'll be ready to fry in minutes the next morning.
