    My Irish Nachos are everything you want in a St Patrick's Day recipe - Tender roasted potatoes, Guinness Cheese sauce, corned beef, & more!

    You know that thing, where you go to the local Irish pub (in the United States) for a little St. Patrick's Day snacking, order something with a name like โ€œIrish pub nachosโ€, and you get either:

    Regular nachos - complete with favorite nacho toppings like pico de gallo, ground beef, melty cheese, bell peppers, jalapenos, salsa, etc - just served on either potato slices, waffle fries, potato chips, french fries, steak fries, or potato wedges?

    Maybe even just a pile of Loaded Baked Potato Skins?

    Sure, each can be a fun twist on traditional nachos, but none really scream โ€œIrish dishโ€ to me, you know?

    More suitable as a big game day snack, than as the perfect dish for March 17th revelry, IMHO.

    So here I am with my Irish nachos recipe!

    My easy Irish nachos start out on a bed of crispy roasted potatoes, yes, but thatโ€™s where the similarity ends.

    The crispy potatoes are topped with a beer cheese sauce - using Guinness, obviously - and topped with a few delicious toppings that are more suited to the occasion.

    Corned beef and cabbage, of course - as well as a horseradish sour cream - the perfect addition to your St Patrickโ€™s Day party menu!

    So, this St Paddyโ€™s Day ... skip the Irish pubs when youโ€™re craving a tasty twist on nachos.

    These Irish nachos are super easy to make, and disappear FAST!

    Letโ€™s get to it...

    Note: Raw cabbage on nachos may sound kind of weird, but I recently designed an amazing recipe for Ahi Tuna Nachos. I added purple cabbage on that one - specifically looking for colour - and I LOVED the crunch and flavour it added!

    Ingredients

    This Irish potato nachos recipe uses mostly really simple ingredients that should be easy to find in any grocery store. A few notes for you:

    Russet Potatoes

    This is the main ingredient of the recipe, and these thin-sliced potatoes take the place of tortilla chips in regular nachos.

    I donโ€™t recommend swapping these out for a different potato - the moisture content / waxiness of other varieties doesnโ€™t make for as nice of a texture in this particular recipe.

    The potatoes are tossed in a bit of vegetable oil or canola oil (you can use olive oil if needed), and seasoned with salt and black pepper.

    Shredded Cheddar Cheese

    I like to use a sharp cheddar cheese as the base for my Guinness cheese sauce, but feel free to use a medium cheddar or mild cheddar if you prefer.

    If youโ€™d like a bit more kick, use some Pepper Jack in place of some or all of the cheddar.

    Corned Beef

    I used some of my Homemade Corned Beef in making this recipe, but feel free to use leftover corned beef.

    While I like to use an actual brisket, you could make this with chopped or slices deli corned beef, if youโ€™d like a quicker option and donโ€™t have leftover brisket on hand!

    Guinness Beer

    I use flat, room temperature Guinness for this, to stay on theme, but if you donโ€™t have Guinness, any dark beer would work.

    If youโ€™d like to go gluten free, just use gluten free beer.

    If you would like to skip the beer altogether, use chicken broth or beef broth in place of the beer.

    Everything Else

    Rounding out this recipe, youโ€™ll need:

    Green cabbage
    Green onions
    Milk (or milk alternative)
    Sour Cream
    Horseradish
    Dijon mustard
    Corn starch
    Caraway Seeds, optional

    How to Make Irish Nachos

    The full recipe is in the recipe card at the end of this post, here is a pictorial walk through.

    Baked Potato Slices

    First thing you need to do is get the potatoes cooking.

    Preheat oven to 425 F, line 2 baking sheets with parchment paper. Scrub potatoes, blot try with a paper towel.

    Slice potatoes into ยผ inch slices - I like to use a mandolin set to a ยผ" thick slice - place in a large bowl.

    Drizzle potatoes with the vegetable oil, season with salt and pepper, and gently toss to coat.

    Spread potato slices out in a single layer on each baking sheet.

    Bake in the preheated oven for 25 minutes.

    2 parchment lined pans with potato slices across each.

    As the potato slices are baking, I like to prepare the topping ingredients - slice the cabbage and green onions, chop up the corned beef, etc, as well as shred the cheese for the sauce.

    Set aside.

    In a small bowl, whisk together the sour cream with 1 tablespoon of horseradish. Taste, add more horseradish, if desired, then season with salt and pepper.

    Once the 25 minutes are up, flip each potato slice and bake each sheet pan for another 25 minutes.

    As the potatoes bake for the second time, make your Guinness cheese sauce:

    Guinness Cheese Sauce

    In a medium bowl, toss the shredded cheese with the cornstarch, evenly coating the cheese. Set aside.

    In a small saucepan, whisk together the beer, milk, and mustard. Heat over medium-high heat until simmering.

    Add the cheese, a handful or so at a time, stirring to combine and melt.

    Once all cheese is melted and smooth, season with salt and pepper, to taste. Keep warm until the potato slices are finished.

    Assembly

    Arrange about half of the potato slices on your serving platter.

    Scatter about half the cabbage, then drizzle with half the sauce. Top with about half the corned beef.

    Repeat with a second layer, making a heaping pile using up the remaining potato slices, cabbage, sauce, and corned beef.

    Spoon some of the horseradish sour cream on top of the nachos, scatter some green onions, and a light sprinkling of caraway seeds, if desired.

    Serve immediately, with a side of sour cream.

    Leftovers

    Irish Nachos are DEFINITELY best eaten immediately after assembly.

    If you do find yourself with leftover irish nachos, you can keep them in an airtight container in the fridge for a few days, and reheat in the microwave.

    When at all possible, though, plan for leftovers - the unassembled components can be stored separately, reheated, and assembled fresh for much better results!
