Does March come in like a lion, and out like a lamb? Or, does it come in like a lamb and go out like a lion? I always get those two mixed up. Kind of like starve a cold and feed a fever, or feed a fever and starve a cold? I’m never quite sure.
But what I am sure about is how delicious this Irish corned beef boxty is. Make one for St. Patrick’s Day and it’s sure to be your lucky day!
**Please Note – The printable recipe card with detailed instructions, complete ingredient measurements, and nutritional information for making Irish Corned Beef Boxty is available near the end of this post.

The ingredient list for making Irish Corned Beef Boxty;
- 2 cups mashed potatoes (leftovers are great for this recipe)
- Prepared Horseradish
- Grated Idaho Potatoes
- Milk
- All-Purpose Flour
- Salt and Pepper
- Baking Powder
- 3 Eggs
- Corned Beef, chopped (10 ounces)
- Grated Swiss Cheese (10 ounces)
- 1,000 Island Dressing, optional
It’s been such a brutal winter for most of the country with record-breaking freezing temperatures and record-breaking snowfall. Is this now what winter is destined to be? I sure do hope not!
However, two things you can always count on of in the month of March (despite the weather) is that college basketball takes center stage (with anyone and everyone talking brackets). And, on March 17th (St. Patrick’s Day) everyone turns a little Irish, including me! Eating a delicious corned beef boxty is a great way to celebrate being Irish for a day!

How to make an Irish Boxty filled with corned beef and Swiss cheese;
- In a large bowl mix the mashed potatoes and horseradish.
- Grate 2 cups of Idaho potatoes (I leave the skin on), and dry them in a clean towel by squeezing out all the moisture.
- Add the dried grated potatoes into the bowl with the mashed potatoes.
- Stir in flour, baking powder, salt, pepper and mix well.


- In a small bowl whisk together eggs and milk. Add the egg and milk into the potato mixture.
- Stir well to form a creamy, thick pancake batter consistency.


- Add oil to a large skillet and drop enough batter into the skillet to form a 6″ pancake which is approximately ¼” thick.
- Cook until browned on one side.
- Flip the pancake and cook on the second side until browned.


- Add the corned beef and Swiss cheese to half of the cooked pancake.
- Use a spatula to flip the plain half of the pancake over the filled half.
- Cover the skillet loosely with a lid or foil and cook until the cheese has melted.
- Serve the Irish boxty hot, with 1000 island dressing for dipping if desired.



What is the proper consistency for the potato pancake batter?
Since you’ll be using leftover mashed potatoes, and everyone’s mashed potatoes are slightly different consistency, when you mix up the pancake batter for the boxty, it should be similar in thickness as a pancake batter.
Easily pourable, but not too runny.
Can instant mashed potatoes be substituted for the leftover mashed potatoes?
- I don’t see why not. As long as the instant mashed potatoes are seasoned well, and made to a thicker consistency, they should work equally as well as homemade.
Can I swap out a different kind of meat and/or cheese for this stuffed boxty recipe?
- Yes. Of course!
- Making the boxty (potato pancake) is a method, but what you stuff it with is your choice. Go crazy and have fun!
Is there a swap I can use for the prepared horseradish?
- Good question! Glad you asked! 😉
- Why not add some Dijon mustard or maybe even a touch of beer to the batter? As long as you thicken the batter accordingly with additional flour (so it’s not too wet), you’ll be fine experimenting! Again, have fun!

What do you serve as a side dish with this?

Hi, Lynne! That's a good question. I wouldn't serve potatoes for sure, but I would serve a cabbage side dish to go along with the St. Patrick's day theme. I have a few that I'll link here for you. They both really good. One is cold and one is hot. The first one is hot. I made this one last night > https://www.kudoskitchenbyrenee.com/creamed-cabbage-bacon-caraway/ This one is also very popular and is great all summer long. It's cold > https://www.kudoskitchenbyrenee.com/copycat-sunflower-crunch-kale-cabbage-salad/ Thanks for the great question. I hope you'll also enjoy these recipes. Take care and be well. Renee

I love stuffed Boxty. One suggestion, though. When you pour the potato mix for the “pancake” aim for somewhere in between typical pancake thickness and crepe thinness. It’s basically a potato omelette, but the potato cake doesn’t exactly fold like straight eggs. Just something to consider, after countless failed folded Boxty that broke at the fold... which are still delicious.

Thank you so much for your comments, John. I appreciate your feedback. The only thing I can think of because I didn't have this problem, is that maybe your premade mashed potatoes were a little dryer than what I was using. I will adjust the post with the information you've suggested so others won't have this same problem. Thanks so much. Glad they were still delicious! Have a great day! Renee

How did I not know that boxty was A Thing? I love that you left the skin on the potatoes. This is definitely my kind of meal!
