What Goes into this Recipe
In this post, we detail how to make corned beef potato pancakes, and the ingredient list and images reflect this. However, the basic recipe and process is the same no matter what protein you choose to add.

Ingredient Notes & Substitutions
★ Mashed potatoes: Use leftover mashed potatoes of any variety, including instant mashed potatoes.
Keep in mind, the mashed potatoes provide the flavor base; so if you use cheesy potatoes, for example, you will have cheesy potato pancakes.
★ Corned beef: Use any leftover corned beef, diced ⅛-¼ inch.
Substitutions: You can use ham, chicken, roast beef, hamburger, veggie crumbles, sausage, or anything else that sounds good to you.
You can also leave out the meat entirely.
★ Onion: Use any type of onion. We prefer to use sweet onions for this recipe. Include the onion juice with the grated onions.
Tip: Roasted garlic is also fabulous in potato pancakes.
★ Flour: You can use all-purpose flour; however, we recommend using Wondra.
Wondra, or instant flour, is finely ground flour that has been pre-cooked and dried. This allows it to dissolve in batters more quickly than all-purpose flour, and alleviates lumps.
★ Pepper: We prefer to use white pepper for this dish for its subtler flavor; however, you can use whatever pepper you like. Paprika is also a good addition.
How to Make Potato Pancakes with Corned Beef
Prep Diced Meat
Heat a small skillet over medium-high heat. When the skillet is hot, add the diced corned beef.
Substitutions: If you use very lean meat in place of the corned beef, add a teaspoon or two of oil to the pan before adding the diced meat.
Stirring frequently, fry it as you would chopped bacon; until the sides are brown and crispy.

Make Batter
In a medium mixing bowl, whisk the egg and then stir in the mashed potatoes and grated onion.
Sprinkle the flour over the top of the potato mixture, and stir to mix thoroughly.
Add the fried corned beef to the mashed potato batter and mix to incorporate it evenly.
People make mashed potatoes differently, and this can affect how the batter turns out. Potato pancake batter should be the consistency of thick, but pourable, pancake batter.
- If the batter seems too thin: Add flour to the batter 1 tablespoon at a time, until the batter reaches the desire consistency.
- If the batter seems too thick: Add water or milk to the batter 1 tablespoon at a time, until the batter reaches the desire consistency.

Fry Potato Pancakes
Preheat griddle to 325°F | 162°C, or heat a heavy skillet over medium heat.
When the griddle or skillet is hot, oil the surface as you would for pancakes and pour ¼ cup batter onto the hot surface. Brown on both sides.

Serve potato pancakes warm, with sour cream or applesauce on the side.

FAQs & Expert Tips
Irish Boxty
Boxty are Irish potato pancakes made from a combination of grated and mashed potatoes. Put a true Irish spin on corned beef potato pancakes by substituting grated potatoes for half of the mashed potatoes in this recipe. (Use 1 cup of mashed potatoes and one cup of grated potatoes. The grated potatoes must be squeezed and well-drained.)
Potato cakes usually fall apart because they are too wet, don't have enough flour, or a combination of the two. This most often happens because of variations in how and with what people make their mashed potatoes.
Correct this imbalance by adding flour to the batter 1 tablespoon at a time, until you get a batter that will hold together when fried.

Corned beef potato pancakes are particularly delicious with a drizzle of Russian dressing.
