My Irish neighbor brought these to the potluck and the pan was licked clean in minutes. It is so easy with just 4 ingredients.

These oven baked 4-ingredients Irish nachos are the kind of potluck dish that disappears before you can even set the pan down. Instead of tortilla chips, thinly sliced potatoes form the base—an idea often credited to Irish pubs in the U.S. that wanted something heartier and more familiar to potato-loving crowds.

Here, we keep it wonderfully simple: potatoes, sharp cheddar, bacon, and green onions. Everything bakes on one foil-lined sheet pan, giving you crispy edges, gooey cheese, and smoky bacon in under an hour with almost no cleanup.

Serve these Irish nachos straight from the sheet pan while they’re still hot and the cheese is stretchy. They pair well with cold beer, hard cider, or a simple sparkling water with lime.

For dipping, set out small bowls of sour cream or plain Greek yogurt and a bit of hot sauce or grainy mustard. They’re perfect as a game-day snack, a casual appetizer for a potluck, or as a fun side next to grilled sausages, burgers, or a big green salad to balance the richness.

Oven Baked 4-Ingredients Irish Nachos

Servings: 6 

Ingredients

2 pounds russet potatoes, scrubbed and thinly sliced into 1/8–1/4 inch rounds

8 ounces sharp cheddar cheese, shredded

6 slices thick-cut bacon, cooked crisp and crumbled

3 green onions, thinly sliced 

Directions

Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet with aluminum foil for easy cleanup.

Scrub the potatoes well and pat them dry. Leaving the skins on, slice the potatoes into 1/8–1/4 inch thick rounds. Try to keep the slices as even as possible so they cook at the same rate.
