Full Ingredients

Potato Pancakes

• 1.25 kg starchy potatoes (about 6 medium), peeled
• 1 medium yellow onion (150 g), peeled
• 2 large eggs (about 100 g), lightly beaten
• 60 g (1/2 cup) all-purpose flour or potato starch
• 1 1/2 tsp fine sea salt
• 1/2 tsp freshly ground black pepper
• Optional: 1/2 tsp baking powder (for slightly lighter texture)

For Frying

• 180 ml (3/4 cup) neutral oil (sunflower, canola, or grapeseed), plus more as needed
• 2 tbsp butter or ghee (for flavor and browning)

For Serving — Simple

• 240 g (1 cup) full-fat sour cream
• 2 tbsp finely chopped chives or dill
• Optional: lemon wedges for a bright squeeze

Mushroom Gravy (Optional but Excellent)

• 450 g mixed mushrooms, sliced (cremini, shiitake, oyster; include a few wild if available)
• 2 tbsp unsalted butter
• 1 tbsp olive oil
• 1 small shallot (40 g), finely minced
• 2 garlic cloves, finely minced
• 1 tsp fresh thyme leaves (or 1/4 tsp dried)
• 60 ml (1/4 cup) dry white wine
• 240 ml (1 cup) vegetable or beef stock
• 120 ml (1/2 cup) heavy cream
• 1 tsp soy sauce (or Worcestershire if not vegetarian)
• 1 tsp Dijon mustard (optional, for depth)
• Fine salt and black pepper, to taste
• 2 tbsp chopped fresh parsley, for finishing

Step-by-Step Instructions

Step 1: Preheat and set up

Heat your oven to 200°F (95°C). Set a wire rack inside a rimmed baking sheet for draining and keeping pancakes crisp between batches. Gather a box grater (large holes) or food processor with a coarse grating disk, a large nonstick or cast-iron skillet, and a clean kitchen towel.

Step 2: Cook the mushroom gravy (optional but recommended)

In a wide skillet over medium-high heat, melt the butter with the olive oil. Add the mushrooms in an even layer with a pinch of salt; cook undisturbed for 3 minutes, then stir and continue cooking until deeply browned and their moisture evaporates, 6–8 minutes total. Reduce heat to medium, add the shallot, garlic, and thyme; cook 1–2 minutes until fragrant. Deglaze with the white wine, scraping up browned bits; simmer 1–2 minutes until almost dry. Add stock and simmer 3–4 minutes to reduce slightly. Stir in cream, soy sauce, and Dijon (if using); simmer on low, stirring, until glossy and nappe-thick, 4–6 minutes. Season to taste with salt and pepper, then hold warm on low heat. Just before serving, stir in parsley.

Step 3: Grate and drain the potatoes and onion

Grate the potatoes and onion on the large holes of a box grater (or use a food processor). Immediately transfer to a clean kitchen towel and squeeze firmly over a bowl to expel as much liquid as possible. Let the expressed liquid sit undisturbed for 5 minutes so the potato starch settles to the bottom. Pour off the dark liquid, then scrape the white starch from the bowl and reserve it.

Step 4: Build the batter

In a large mixing bowl, whisk the reserved potato starch with the eggs, flour (or potato starch), salt, pepper, and baking powder (if using). Fold in the grated potato and onion until evenly coated. The mixture should be thick but spoonable; if too loose, add 1–2 tbsp more flour; if too stiff, add 1–2 tbsp water.

Step 5: Fry to lacy-edged crispness

In a large skillet over medium-high heat, add enough oil to create a 3–4 mm shallow layer and add the butter or ghee. Heat until shimmering and 360°F (182°C) if using a thermometer. Working in batches, drop 2–3 tablespoons of batter per pancake and flatten to 9–10 cm (3.5–4 inches) with a spoon. Fry 3–4 minutes per side until deep golden brown with frilly, lacy edges. Adjust heat to keep the oil hot but not smoking; add more oil as needed between batches.

Step 6: Drain and keep crisp

Transfer pancakes to the wire rack and keep in the warm oven while you fry the remaining batter. Sprinkle with a pinch of salt while hot to sharpen the flavors.

Step 7: Serve two ways

For the simple version, spoon sour cream over hot pancakes and shower with chives or dill; add a squeeze of lemon if you like. For the lavish version, stack pancakes on warm plates and ladle with mushroom gravy; finish with parsley and cracked black pepper. Serve immediately—crispness waits for no one.

Pro Tips

• Starch matters: Russet or other starchy potatoes crisp best. Reserving and re-adding the potato starch boosts crunch.
• Squeeze hard: Get the potato mixture very dry before mixing; moisture is the enemy of browning.
• Heat control: Aim for about 360°F (182°C). Too cool and pancakes drink oil; too hot and they scorch before cooking through.
• Wire rack > paper towels: A rack prevents steam buildup so the bottoms stay crackly.
• Gravy first: Make the mushroom gravy before frying so you can serve the pancakes immediately at peak crisp.

Variations

• Classic sweet-savory: Serve with applesauce instead of sour cream—traditional and delightful.
• Herb and spice: Add 2 tbsp chopped dill or parsley and 1/2 tsp sweet paprika to the batter.
• Cheesy edges: Sprinkle a pinch of finely grated Parmesan around the batter as it hits the pan for ultra-crisp frico-like lace.

Storage & Make-Ahead

Cooked pancakes keep refrigerated up to 3 days or frozen up to 2 months. Reheat from chilled at 425°F (220°C) on a rack-lined sheet for 10–12 minutes, or from frozen for 15–18 minutes, until hot and re-crisped; broil 30–60 seconds if needed. Mushroom gravy keeps 3–4 days in the fridge; rewarm gently with a splash of water or stock. For prep-ahead, you can grate potatoes up to 4 hours in advance and store submerged in cold water; drain, squeeze very dry, and proceed (do not mix the batter early, as it darkens and softens).
