Crisp-edged, tender-centered Irish Boxty Potato Pancakes are a practical, satisfying way to turn simple potatoes into a stovetop meal. You’ll grate some potatoes raw for lacy crunch, mash the rest for a soft interior, then pan-fry small cakes and finish with tangy scallion sour cream and a squeeze of lemon. Expect a savory potato flavor with gentle tang from buttermilk and just enough flour to bind.

If it’s a busy weeknight, set a pot of salted water to boil for the mash first, then grate the remaining potatoes while it heats. Cooking with kids around or working in a tiny kitchen? Mix the scallion sour cream before you start frying so hot pancakes don’t wait.

These pancakes show up on breakfast and pub-style menus across Ireland and are easy to enjoy any time of day. The method here suits new and practiced home cooks who like clear cues and minimal specialty gear.

Substitutions

Yukon Gold potatoes work, but expect a slightly denser center and less-crisp edges than russets.
No buttermilk? Use 3/8 cup / 90 ml milk + 2 tbsp / 30 ml plain yogurt or 1/2 cup whole milk + 1 tsp lemon juice (stir and rest 5 minutes).
Gluten-free: Swap in a cup-for-cup gluten-free all-purpose blend and rest the batter 10 minutes to hydrate.
Dairy-free sour cream: Use a thick unsweetened plant-based yogurt; season with extra lemon for tang.

Step-by-Step Instructions for Irish Boxty Potato Pancakes

Make the scallion sour cream. In a small bowl, stir together sour cream, scallions, lemon zest and juice, salt, and pepper. Taste; it should be bright and lightly salty. Cover and refrigerate while you cook.
Boil half the potatoes for mash. Dice half (340 g) of the peeled potatoes into 1/2-inch cubes. Drop into a pot of cold, well-salted water (it should taste like the sea). Bring to a boil, then simmer until very tender, about 12–15 minutes. Drain well and let steam off for 5 minutes. Mash until smooth.
Grate and squeeze the rest. Coarsely grate the remaining 340 g potatoes on the large holes of a box grater onto a clean kitchen towel. Gather the towel and twist hard over the sink to expel as much liquid as possible. If time allows, let the squeezed liquid sit for 10 minutes in a clear bowl, pour off the water, and scrape the white potato starch back into the grated potatoes—it helps binding without extra flour.
Mix the dry ingredients. In a medium bowl, whisk flour, baking soda, 1 tsp kosher salt, and the black pepper.
Build the batter. In a large bowl, combine the warm mashed potatoes and the squeezed grated potatoes with the egg. Sprinkle over the dry mixture and fold gently. Drizzle in 1/2 cup buttermilk and stir just until no dry flour remains. The batter should be thick and scoopable, not runny; add a spoonful more buttermilk only if it’s crumbly.
Preheat the pan properly. Heat a large cast-iron or nonstick skillet over medium for 2–3 minutes. Add 1 tbsp butter + 1 tbsp oil. When the butter foams and the fat shimmers, you’re ready to fry.
Fry the first batch. Scoop heaping 1/4-cup portions into the pan (3–4 pancakes, spaced out). Flatten gently to about 1/2 inch thick and 3.5–4 inches wide. Cook 4–5 minutes until the bottoms are deep golden and the edges look set.
Flip and finish. Slide a thin spatula under each cake and flip carefully. Cook another 4–5 minutes until the second side is golden and the center feels set when pressed. Transfer to a wire rack set over a sheet pan. Sprinkle lightly with the remaining 1/4 tsp kosher salt. Keep warm in a 200°F / 95°C oven while you finish the rest.
Refresh the fat and repeat. Add another 1 tbsp butter if the pan looks dry, and fry remaining batter in batches. Avoid crowding; steam softens crusts.
Serve hot. Top each pancake with a spoonful of scallion sour cream, more sliced scallions if you like, and a squeeze of lemon. The lemon wakes up the potatoes.

Kitchen note: If the outsides brown before the centers set, your heat is too high. Lower to medium-low so the batter cooks through and the crust develops without scorching.

What to Expect

Texture: Expect crisp, browned edges with a tender, slightly fluffy middle from the mash-and-grate blend. They won’t be brittle-crisp like hash browns, and that’s by design.
Flavor: Clean potato flavor leads, supported by light tang from buttermilk and a hint of allium from the scallion sour cream. Lemon at the table brightens each bite without making the cakes taste sour.
Variability: Russets give the best contrast of crisp and soft. Yukon Golds brown beautifully but can eat a touch denser. Cast iron browns more evenly than thin steel; nonstick makes flipping easy but may produce paler crusts.

Kitchen note: Size affects doneness. Pancakes thicker than 1/2 inch risk a gummy center; thinner than 3/8 inch cook fast but can overcrisp. Keep them uniform for even batches.

Ways to Change It Up

Vegetarian to Vegan: Use plant-based milk soured with lemon, a flax “egg” (1 tbsp ground flax + 3 tbsp water, rested 10 minutes), and fry in oil. The interior will be slightly less fluffy without egg, but the cakes still bind well if the grated potatoes are squeezed thoroughly.
Spicier: Add 1/2 tsp ground white pepper to the batter and fold 1 finely chopped green chile or 1/2 tsp Aleppo pepper into the sour cream. Heat reads well against the tangy topping. Trade-off: heat can overshadow the potato if you add too much.
Faster, Fewer Dishes: Skip mashing from scratch by using 1 cup cold leftover mashed potatoes plus about 225 g freshly grated potatoes. Stir in buttermilk gradually until the batter looks like thick pancake batter. Trade-off: seasoning varies with your mash, so taste and salt accordingly.

Kitchen note: If using leftover mashed potatoes that already contain butter/cream, start with just 1/4 cup buttermilk and add by tablespoons; it’s easy to thin, hard to thicken without extra flour.

Serving and Storage

Serve boxty hot from the skillet with scallion sour cream and lemon. Crispy bacon, smoked salmon, or a fried egg are all classic partners. For a fresh, no-chop side, try this quick Cucumber Salad That Stays Crunchy in 15 Minutes. On cooler nights, pair with a simple soup like French Onion Soup with Deep Flavor, Simple Steps.

To hold for the table, keep finished pancakes on a wire rack in a 200°F / 95°C oven for up to 30 minutes. Avoid stacking—they’ll steam and soften. Leftovers keep up to 3 days in an airtight container in the fridge. Reheat on a rack over a sheet pan at 400°F / 205°C for 8–10 minutes or in a lightly buttered skillet over medium heat. Freezing isn’t ideal for texture, but if needed, freeze in a single layer, then bag for up to 1 month; re-crisp from frozen in a 400°F oven for 12–15 minutes.

Kitchen note: Holding on a rack, not on paper towels, preserves the underside crust. Paper traps steam and can make the bottoms leathery.

Cultural Context

Boxty appears across Ireland in multiple forms: griddled pancakes like these, boiled dumpling-style slices, and baked loaves. The mix of raw grated and cooked mashed potato shows how cooks stretched staples while chasing a pleasing texture. Potatoes became central to Irish diets from the 17th to 19th centuries, and many regional dishes grew around them. For an accessible overview of how the potato shaped Ireland’s economy and daily meals, see this short history from Ireland’s public broadcaster: Why the potato mattered so much in Ireland.

Common Questions and Troubleshooting

My pancakes are falling apart in the pan. What did I miss?
Squeezing the grated potatoes very dry is key. Too much residual liquid dilutes the batter and prevents browning. Also check that you used at least 2/3 cup / 85 g flour and didn’t over-thin with buttermilk.
The centers seem gummy while the outsides are brown.
Lower the heat and extend cooking time by a minute or two per side. Thick cakes need gentler heat. Next time, keep thickness to about 1/2 inch.
Can I make the batter ahead?
Not recommended. Raw grated potatoes oxidize and the leavening loses power. Instead, grate and squeeze potatoes up to 2 hours ahead, store them submerged in cold water, then drain and squeeze again before mixing just before frying.
I only have baking powder. Can I use it?
Yes—use 3/4 tsp baking powder and skip the baking soda. The lift is slightly less pronounced, but it works fine, especially if your buttermilk is on the thin side.
Are scallions required in the cakes?
No. The scallion flavor is primarily in the sour cream here. If you want a mild onion note in the cakes, fold 1 thinly sliced scallion into the batter; reduce salt slightly.
How do I keep the first batch warm without softening?
Hold finished pancakes on a wire rack in a 200°F / 95°C oven, uncovered. Avoid covered containers and stacking.
Can I air-fry these?
Boxty are best pan-fried. You can reheat cooked pancakes in an air fryer at 375°F / 190°C for 5–6 minutes to re-crisp, but air-frying raw batter won’t set properly.
What oil should I use?
A butter–oil combo works well: butter for flavor, oil for a higher smoke point. If you prefer all butter, keep the heat moderate and wipe the pan if the milk solids start to darken.
