Intensity: Easy. This recipe requires basic cooking skills like boiling, mashing, and shallow frying. The most important part is gentle handling to keep the cakes intact.
Servings: Makes about 8-10 medium-sized cakes (serves 4 as a main or 6-8 as a starter)
Dietary: This recipe is vegetarian. To make it gluten-free, substitute the all-purpose flour with a good quality gluten-free flour blend (one that includes xanthan gum is best). The smoked salmon topping can be omitted for a vegetarian version, or replaced with a poached egg.
Ingredient List
For the Potato Cakes:
2 lbs (about 900g) Russet or Yukon Gold potatoes, peeled and quartered
4 large scallions (spring onions), finely sliced (white and green parts)
1/2 cup (60g) all-purpose flour, plus extra for dusting
1 large egg, lightly beaten
1 tsp lemon zest (from about 1/2 a lemon)
1 tsp kosher salt, plus more for the water
1/2 tsp freshly ground black pepper
Pinch of cayenne pepper (optional, for a little warmth)
4-6 tbsp vegetable oil or clarified butter (ghee), for frying
For the Topping:
4 oz (115g) high-quality smoked salmon
1/2 cup (120ml) crème fraîche or sour cream
2 tbsp fresh dill, finely chopped, plus extra sprigs for garnish
1 tbsp fresh lemon juice
Flaky sea salt (like Maldon), for finishing
Instructions
Step 1: Prepare the Potatoes (Time: 20 mins | Intensity: Easy)
Place the peeled and quartered potatoes in a large pot and cover with cold water by about an inch. Add a generous tablespoon of salt to the water. Bring to a boil over high heat, then reduce the heat to a simmer. Cook for 12-15 minutes, or until the potatoes are fork-tender (a knife should slide in with no resistance). Be careful not to overcook them, or they’ll become waterlogged.
Drain the potatoes thoroughly in a colander. Return them to the hot pot and shake them over low heat for a minute or two to evaporate any excess moisture. This is a crucial step for ensuring your potato cakes aren’t soggy.
Step 2: Make the Potato Mixture (Time: 10 mins | Intensity: Easy)
While the potatoes are still hot, transfer them to a large mixing bowl. Use a potato masher or a ricer to mash them until completely smooth. You want a fine, lump-free texture.
Add the finely sliced scallions, 1/2 cup of flour, the beaten egg, lemon zest, 1 teaspoon of salt, black pepper, and cayenne (if using). Mix with a fork or your hands until everything is just combined. Be careful not to overmix, as this can make the cakes gluey. The mixture should be soft but hold its shape.
Step 3: Shape the Potato Cakes (Time: 10 mins | Intensity: Easy)
Lightly flour your hands and a clean work surface. Scoop up about 1/3 cup of the potato mixture and gently shape it into a patty about 3/4-inch thick. Don’t pack it too tightly; a gentle hand yields a lighter cake. Place the formed cake on the floured surface and repeat with the remaining mixture. You should have 8-10 cakes.
If you have time, place the shaped cakes on a parchment-lined baking sheet and refrigerate for 15-30 minutes. This helps them firm up and hold their shape even better during frying.
Step 4: Fry to Golden Perfection (Time: 15 mins | Intensity: Medium)
Heat 2 tablespoons of oil (or clarified butter) in a large non-stick or cast-iron skillet over medium-high heat. The oil is ready when it shimmers and a tiny piece of potato mixture sizzles immediately upon contact.
Carefully place 3-4 potato cakes into the hot skillet, making sure not to overcrowd the pan. Reduce the heat to medium. Fry for 4-5 minutes per side, until the cakes are deep golden brown and crispy. Resist the urge to move them around too much; let them form a good crust. Flip carefully using a thin spatula.
Transfer the cooked cakes to a wire rack set over a baking sheet (this keeps them crispier than paper towels). Place them in a warm oven (about 200°F / 90°C) while you cook the remaining batches, adding more oil to the pan as needed.
Step 5: Make the Topping & Serve (Time: 5 mins | Intensity: Easy)
While the last batch is frying, make the dill crème fraîche. In a small bowl, stir together the crème fraîche, chopped dill, and lemon juice.
To serve, place one or two warm potato cakes on a plate. Top with a generous dollop of the dill crème fraîche. Drape a ribbon of smoked salmon over the top. Garnish with a small sprig of fresh dill and a tiny sprinkle of flaky sea salt. The salt adds a wonderful final crunch and pop of flavor. Serve immediately.
Chef’s Tips for Success
The Right Potato: Starchy potatoes like Russets or Yukon Golds are ideal. They mash up light and fluffy, which helps create a tender interior and a crisp exterior. Waxy potatoes (like red potatoes) will result in a dense, gluey cake.
Don’t Overwork the Dough: Mix the ingredients just until they come together. Overworking the potatoes will release too much starch and result in tough, gummy cakes.
Chill Before Frying: If you have the time, chilling the shaped cakes for 15-30 minutes is a game-changer. It allows the starch to firm up, making them much less likely to fall apart in the pan.
Don’t Crowd the Pan: Give each cake some breathing room. Overcrowding lowers the oil temperature, leading to steaming instead of frying, which prevents that beautiful golden crust from forming.
Storage & Reheating
To Store: Cooked potato cakes can be stored in an airtight container in the refrigerator for up to 3 days.
To Reheat: The best way to revive their crispiness is in a skillet. Add a little oil to a pan over medium heat and fry for 2-3 minutes per side until heated through and re-crisped. You can also reheat them in a 375°F (190°C) oven on a wire rack for about 10 minutes.
To Freeze: Freeze the uncooked, shaped cakes on a baking sheet until solid. Transfer them to a freezer-safe bag. Fry from frozen, adding a few extra minutes to the cooking time.
Variations & Substitutions
Cheesy Potato Cakes: Add 1/2 cup of grated cheddar, Parmesan, or Gruyère cheese to the potato mixture.
Herb & Garlic: Swap the scallions for 2 tbsp of chopped fresh chives and parsley, and add 1 minced clove of garlic to the mixture.
The Breakfast Stack: Omit the salmon and top each cake with a perfectly poached or fried egg and a drizzle of hollandaise sauce.
Simple Side Dish: Serve the potato cakes plain, or with a dollop of sour cream or applesauce alongside roasted meats or sausages.
