Let me set the scene.
It’s 4 PM. Friends are showing up at 6. You said — and I quote — “oh don’t worry, I’ll make something.” You have potatoes. You have cheese. You have approximately zero desire to do anything that involves more than one pot.
That was me last St. Patrick’s Day. And also, honestly, three Sundays ago.
Here’s the thing about Irish Nachos that nobody talks about: they sound like you tried. Crispy potato slices layered with toppings? People think you did a whole thing. You did not do a whole thing. You sliced some potatoes and remembered you had shredded cheese in the back of the fridge.
I’ve made this recipe more times than I can count, which is a little embarrassing but mostly just practical.

Wait, What Are Irish Nachos?
It’s nachos but the chips are potatoes. Sliced into rounds, roasted until crispy, then piled with cheese and whatever else you want.
I know. I know! Why did nobody tell us this was an option? I spent years eating tortilla chips going soggy under cheese like some kind of fool and THIS whole time potatoes were just sitting there, structurally superior, asking to be used.
The first time I had them was at this pub-style place near my old apartment. I ordered them mostly because the name confused me and I came away genuinely changed. That’s dramatic but also accurate.
The 4 Ingredients (Yes, Really Just 4)
Russet potatoes. About 2 pounds, sliced into rounds roughly ¼ inch thick. Russets are the move here because they crisp up beautifully and don’t fall apart when you pile stuff on them. I’ve tried Yukon Golds. They’re fine. Russets are better.
Olive oil. Just enough to coat the slices and get them golden. A couple tablespoons. Don’t drown them.
Shredded cheddar cheese. A big generous handful, or two handfuls if you’re having a day. Sharp cheddar melts the best and has enough flavor to carry the whole dish.
Sour cream. Dolloped on top at the end. Cold, creamy, and it cuts through all that richness perfectly.
That’s it. Four things. I mean, you’ll use salt and pepper too, but I’m not counting those because if I have to list salt and pepper as ingredients we’re going to be here all day.
How to Make Them
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment. Two baking sheets if you have a crowd.
Slice your potatoes into rounds, about ¼ inch thick. Even slices matter here — thin ones burn, thick ones stay raw in the middle, and you’ll know immediately which ones you rushed through. (I always rush through a few. They still taste fine.)
Toss the slices in olive oil with a generous pinch of salt and pepper. Lay them out in a single layer on your baking sheet. No overlapping. This is not the time to crowd the pan. Crowded potatoes steam instead of crisp, and we want crisp.
Roast for 25 minutes, flip every slice, then roast another 10-15 minutes until they’re golden and the edges have that slightly caramelized look. You’ll smell when they’re close. Your kitchen will smell incredible and your neighbors will feel something they can’t quite name.
Pull them out, pile them on an oven-safe dish or just use the baking sheet (I use the baking sheet, let’s be real), and scatter the cheddar on top. Back in the oven for 3-4 minutes until melted and a little bubbly.
Top with sour cream and serve immediately. Immediately meaning: put these in front of people before you eat half of them off the pan while “plating.”
A Few Honest Notes
These are best fresh. Like, right out of the oven fresh. If they sit for 20 minutes the potatoes soften and lose some of that crispness. Plan accordingly.
Want to make them more substantial? Bacon bits, sliced jalapeños, green onions — all great. But the base four ingredients? Perfect on their own. I’ve served them at parties where people didn’t even reach for the other food. That is a true story and also slightly concerning about the other food I made.
Also: if you have leftover roasted potatoes from another meal, this is one of the greatest uses for them. Just pop them in a baking dish, cheese on top, five minutes in the oven. Dinner is done. Life is good.
