Honestly, these potato cakes make me wish every day was St. Patrick’s Day.

The first time I made these, it was a chilly March evening and I was rummaging through the fridge, staring at a big bowl of leftover mashed potatoes (the kind you make way too much of on purpose).

It’s the kind of moment where you pause, take a deep breath, and just smile because you know you’re onto something truly special.

What Ingredients You Will Need for Crispy St. Patrick’s Irish Mashed Potato Cakes

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and you can swap in your favorites or adapt for dietary needs.

• For the potato cakes:
  • 2 cups (about 500g) cold mashed potatoes (leftover or freshly made, just make sure they’re not too runny)
  • 1 cup (120g) shredded sharp Irish cheddar cheese (I love Kerrygold for extra creaminess)
  • 2 large eggs (room temperature; helps bind everything together)
  • 1/4 cup (30g) all-purpose flour (or use gluten-free flour for a GF option)
  • 2 tablespoons chopped fresh green onions (adds color and a mild oniony zing)
  • 2 tablespoons buttermilk or milk (gives extra tenderness—use dairy-free if needed)
  • 1/2 teaspoon salt (adjust to taste, especially if your mashed potatoes are already seasoned)
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon smoked paprika (optional, for a little warmth and color)
• For frying:
  • 1/4 cup (60ml) vegetable oil or light olive oil (for crisping—don’t skimp!)
  • Optional: 1 tablespoon unsalted butter (for extra flavor and golden color)
• For garnish:
  • Extra green onions or chives, sliced (for a pop of green)
  • Sour cream or Greek yogurt (to dollop on top—makes it extra festive and creamy)

Ingredient tips: For best results, use firm, chilled mashed potatoes—if they’re too loose, add a touch more flour. Sharp cheddar gives the deepest flavor, but you can sub in regular cheddar or even a dairy-free cheese if you like. In summer, swap in fresh herbs like parsley or dill for the green onions, or toss in leftover cooked bacon for a smoky twist.

If you’re gluten-free, almond flour works well here (just use a bit less so the cakes hold together). For dairy-free, try coconut yogurt and vegan cheddar. The recipe’s forgiving, so don’t be afraid to play around with what you have!

Equipment Needed for Crispy Irish Mashed Potato Cakes

• Mixing bowl: A medium-sized bowl works best for combining the mashed potatoes, cheese, and other ingredients. Glass or stainless steel is easiest to clean.
• Whisk or fork: For beating the eggs and mixing the batter. I use a sturdy fork when I’m in a hurry.
• Measuring cups and spoons: Accurate measurements help your potato cakes hold together and crisp up nicely.
• Nonstick skillet or cast-iron pan: Nonstick pans are great for easy flipping and cleanup, but cast iron gives the best golden crust. If you have a well-seasoned cast-iron, use it!
• Spatula: A flexible silicone spatula makes flipping the cakes a breeze without breaking them.
• Paper towels or wire rack: For draining excess oil and keeping the cakes crispy.

If you don’t have a nonstick pan, a regular skillet works—just be sure to use enough oil and keep an eye on sticking. I’ve even used a griddle for batch cooking when feeding a crowd. For easy cleanup, rinse your pan immediately after cooking (once cool) to avoid stuck-on cheese. If you’re on a budget, basic kitchen tools work just fine—no need for anything fancy!

Preparation Method: How to Make Crispy St. Patrick’s Irish Mashed Potato Cakes with Cheddar

1. Prep the ingredients: Gather all your ingredients and have them measured out. If your mashed potatoes are freshly made, let them cool to room temperature. Cold potatoes work best for shaping.
2. Mix the batter: In a medium mixing bowl, combine 2 cups (500g) mashed potatoes, 1 cup (120g) shredded cheddar, 2 tablespoons chopped green onions, 1/4 cup (30g) flour, 1/2 teaspoon salt, 1/4 teaspoon pepper, and 1/4 teaspoon smoked paprika (if using). Beat 2 eggs with 2 tablespoons buttermilk (or milk) and add to the bowl. Stir everything together until just combined—don’t overmix or the cakes will be tough.
3. Shape the cakes: Using clean hands or a large spoon, form the mixture into 8 round cakes, about 1/2 inch (1.25 cm) thick and 2.5 inches (6.5 cm) wide. If the mixture feels sticky, dust lightly with extra flour. Place the cakes on a plate and chill for 10 minutes (optional but helps them hold shape).
4. Heat the pan: Add 1/4 cup (60ml) oil (and 1 tablespoon butter, if using) to a large nonstick skillet or cast-iron pan. Heat over medium-high until shimmering and a tiny pinch of batter sizzles on contact (about 2 minutes).
5. Cook the cakes: Carefully place 4 potato cakes in the hot oil. Cook for 3-4 minutes per side, until golden brown and crispy. Flip gently with a spatula. If they brown too quickly, lower the heat a tad—slow and steady gets the best crust.
6. Drain and repeat: Transfer cooked cakes to a paper towel-lined plate or wire rack. Repeat with the remaining cakes, adding more oil if needed. Don’t overcrowd the pan—give them space for maximum crispiness.
7. Garnish and serve: Arrange the cakes on a platter. Top with sliced green onions or chives and a dollop of sour cream or Greek yogurt. Serve hot and crispy!

Prep notes: If your mashed potatoes are extra wet, add a tablespoon or two of flour to firm up the mix. Too dry? Splash in a bit more buttermilk. You want the mixture to be thick but pliable, kind of like cookie dough.

Troubleshooting: If cakes fall apart, chill them longer or add more flour. If the outside browns before the inside is hot, lower your heat and cook for a minute longer. For maximum crunch, let the cakes cool on a wire rack instead of a plate.

Cooking Tips & Techniques for Irish Mashed Potato Cakes

Potato cakes can be a little finicky—here’s what I’ve learned after a few disasters and lots of delicious successes:

• Chill the mixture: Cold mashed potatoes make shaping easier and help the cakes hold together in the pan. If you’re in a rush, just pop them in the freezer for 5 minutes.
• Don’t overcrowd the pan: Give each cake plenty of space so the edges crisp up. Crowding leads to steaming, not frying (learned that the hard way!).
• Use enough oil: A generous layer of oil ensures even browning and that classic crunch. Skimping leads to soggy cakes.
• Flip gently: Potato cakes are delicate. Use a thin spatula and flip only once for best results.
• Season to taste: Taste your mashed potatoes before mixing—if they’re already salty, pull back on added salt.

One mistake I made early on was using piping hot mashed potatoes—the cakes became mushy and fell apart. Another time, I forgot to add enough flour, and the cakes stuck like glue to the pan. Lesson learned: balance is key! Timing matters too—don’t rush the browning; let the cakes take their time to build a good crust.

If you’re multitasking (say, making a salad or prepping drinks), keep the cooked cakes warm in a 200°F (95°C) oven while you finish the batch. For extra flavor, try mixing in a pinch of garlic powder or fresh herbs. Consistency is all about keeping the mixture thick and your pan hot but not smoking. Honestly, once you get the hang of it, it’s dangerously easy!

Variations & Adaptations for Crispy Irish Mashed Potato Cakes

Here’s where you can get creative! These potato cakes are super flexible, so let’s talk variations:

• Dairy-free: Use vegan cheddar and non-dairy milk or yogurt in place of buttermilk. I’ve tried it with coconut yogurt, and the flavor is surprisingly good.
• Gluten-free: Swap all-purpose flour for almond or oat flour. Use GF mashed potatoes and double-check your cheese.
• Seasonal flavor: In spring, add chopped fresh parsley or dill. In autumn, mix in a handful of cooked, crumbled bacon or diced cooked apples for a sweet-savory twist.
• Spicy: Stir in 1/4 teaspoon cayenne or a sprinkle of red pepper flakes if you like a little heat.
• Cheese swap: Try swapping cheddar for Gruyère, mozzarella, or Irish blue cheese for a different flavor profile.

If you want to bake instead of fry, shape the cakes and place them on a parchment-lined baking sheet. Brush lightly with oil and bake at 425°F (220°C) for 20-25 minutes, flipping halfway through. They’re a little lighter but still crispy.

For personal taste, my favorite twist is adding chopped cooked ham and a little Dijon mustard to the mix—makes them a hearty brunch showstopper. Allergies? You can skip the eggs and use a flaxseed “egg” (1 tablespoon flaxseed meal + 3 tablespoons water, mixed and left to gel) for binding.

Serving & Storage Suggestions

These crispy Irish mashed potato cakes are best served hot, straight from the pan. A sprinkle of fresh herbs and a dollop of sour cream or Greek yogurt make them look Pinterest-perfect and amp up the flavor. I love piling them onto a rustic wooden board with a side of tangy pickles or a simple green salad—makes for a complete appetizer spread.

Pair with chilled Irish lager, sparkling water, or even a cup of strong black tea for the full St. Patrick’s Day experience. If you want to turn them into a meal, serve alongside roast chicken or a bowl of hearty vegetable soup.

To store leftovers, let the cakes cool completely, then tuck into an airtight container in the fridge. They’ll keep for 3-4 days. For longer storage, freeze on a baking sheet until solid, then transfer to a freezer bag—thaw in the fridge before reheating. Reheat in a skillet over medium heat or in a toaster oven to restore the crispy exterior (microwaves make them soft, so avoid if you can).

The flavors actually deepen after a day or two—so don’t be afraid to make ahead for parties or meal prep. I sometimes sneak a leftover cake for breakfast, topped with a fried egg!

Nutritional Information & Benefits

Each crispy mashed potato cake (based on 8 cakes per recipe) is about 170 calories, with 8g fat, 15g carbs, and 7g protein. The main health highlight here is the potassium and vitamin C from the potatoes, plus a good dose of calcium from cheddar cheese. Green onions bring a little vitamin K and antioxidant power.

If you go gluten-free or dairy-free, nutrition will shift a bit (less calcium, maybe more fiber if using almond flour). These cakes are naturally nut-free, but eggs and dairy are present—be sure to check labels if cooking for allergies. For a lighter option, bake instead of fry and use reduced-fat cheese.

Personally, I love how these cakes offer comfort food vibes but with more protein and real ingredients than most appetizers. They’re filling, satisfying, and can be tweaked for most diets—just another reason to love them!
