Irish Nachos Recipe (Potato Pub Nachos)
Got leftover corned beef? You need to make Irish Nachos!
These aren't the typical nachos you might find at your favorite pub, unless you're in an Irish pub, but if you love nachos as much as I do, you're going to love this delicious spin.
What are Irish Nachos?
Irish Nachos are a spin on Classic Nachos, but instead of tortilla chips, they are replaced with potatoes. The potatoes come in various forms, depending on how you want to serve it.
You can use thinly sliced potatoes, waffle fries, even potato chips. Then, lots of cheese and all your favorite toppings.
My recipe is perfect for leftover corned beef. I use sliced potatoes as the base, and I also include a homemade beer cheese that makes the dish extra special.

The full ingredients list with measurements is listed in the printable recipe card at the bottom of the post.
- FOR THE IRISH NACHOS
- Yellow Potatoes
- Olive Oil

- Paprika (or Cajun seasoning)
- Cooked and Cubed Corned Beef
- BEER CHEESE SAUCE
- Butter
- Flour
- Guinness Blonde Beer (or use your favorite light beer)

How to Make Irish Nachos (Potato Pub Nachos)
Slice the potatoes very thin to about 1/8 inch, then toss them in a bowl with olive oil, granulated garlic, black pepper and paprika.
Bake them at 350°F until they just start to crisp up and the edges brown, 15 minutes or so, then layer them on a baking sheet. Top them with cooked cubed corned beef.
Make the beer cheese sauce by melting the butter in a saucepan. Add the flour and stir to make a roux. Cook a couple minutes to brown, then swirl in your beer. I used Guinness Blonde for this, which worked perfectly, though can use other beer to your preference.
Swirl in your cream cheese and shredded Irish cheddar cheese and what you have is a super creamy DELISH cheese sauce.

Drizzle the cheese over the top of your Irish Pub Nachos, like so, then top with extra shredded cheddar cheese.
At the end, it should look something like this...

Now! Bake for 10 minutes at 350°F (175 C) to warm it up just right for nice melty cheese.
Boom! Done! Your Irish Nachos are ready to serve. Top them with all of your favorite nacho toppings and enjoy! Don't forget the hot sauce.

Recipe Tips & Notes
- Feel free to use leftovers. You can totally use leftover corned beef, which is what we did from our Corned Beef Tacos Recipe. Leftovers rule!
- Use homemade dressing. Yes, you can use store-bought if you're in a pinch. However, using your very own Homemade Thousand Island Dressing is SO satisfying. Truly, I can't even. I just... want... more of this.
- Enjoy it fresh. These Irish nachos don't stay fresh for long, so don't try to make them ahead of time or store for later. Dig in, enjoy, and pair them with a Guinness this St. Patrick's Day. Cheers!

Irish Nachos Recipe (Potato Pub Nachos)
Ingredients
- 1 pound yellow potatoes
- 2 tablespoons olive oil + more as needed
- 1 teaspoon granulated garlic
- 1 teaspoon cracked black pepper
- 1 teaspoon paprika – Or use a nice blend of your favorite Cajun seasonings
- 1 pound cooked corned beef cubed
FOR THE CHEESE
- ½ stick butter
- 2 tablespoons flour
- 8 ounces Guinness Blonde beer
- 3 ounces cream cheese
- 8 ounces shredded white cheddar cheese – bonus points for a good Irish cheddar
FOR SERVING
- 2 jalapeno peppers diced
- 1 medium firm tomato diced
- Chopped green onion
- Homemade Thousand Island Dressing for serving
Instructions
- Slice the potatoes to 1/8 inch slices. I used a mandolin. Add them to a large bowl and toss them with olive oil, garlic, black pepper and paprika or Cajun seasonings.
- Set them onto baking sheets and bake them for 15-20 minutes at 350 degrees, or until they are nicely browned. Remove from heat and layer them together onto a small baking sheet.
- Make your cheese by melting the butter in a pot over medium heat. Add the flour and stir. Cook for 10 minutes while continually stirring, until the roux begins to brown a bit.
- Stir in the Guinness Blonde beer, still stirring continually, until the mixture thickens a bit, about 5 minutes.
- Stir in the cream cheese until melted.
- Stir in most of the shredded cheddar cheese a bit at a time, continually stirring, until it melts through and becomes an AMAZING CHEESE SAUCE. Reserve a bit for later.
- Next, spread the cooked corned beef over the layered potatoes, then drizzle with the awesome beer cheese. Sprinkle on the remaining shredded cheese.
- Bake for 10 minutes at 350 degrees F.
- Remove from the oven and top with jalapeno, tomato, green onion, and your Homemade Thousand Island Dressing as desired. So good!
