Oven-Baked 4-Ingredient Irish Nachos: Crispy, Cheesy, and Perfect for Sharing

A Simple Twist on a Crowd Favorite

These oven-baked Irish nachos are the kind of dish that disappears almost as soon as they hit the table. Instead of traditional tortilla chips, thinly sliced potatoes create a hearty and satisfying base.

This pub-inspired favorite keeps things simple with just four main ingredients: potatoes, sharp cheddar cheese, bacon, and green onions. The result is a delicious balance of crispy edges, melted cheese, and savory flavor—all made on a single sheet pan for easy cleanup.

Perfect for Any Occasion

Irish nachos are incredibly versatile and work well for a variety of occasions. Whether you’re hosting a game-day gathering, attending a potluck, or simply preparing a casual snack at home, this dish fits right in.

They’re best served hot, straight from the pan, when the cheese is still melted and stretchy. Pair them with a refreshing drink like sparkling water with lime, or serve alongside your favorite dips such as sour cream or plain Greek yogurt.

Ingredients

Servings: 6

• 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

Step-by-Step Directions

1. Prepare the Oven and Pan

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

2. Slice the Potatoes

Scrub the potatoes thoroughly and pat them dry. Slice them into even rounds, about 1/8–1/4 inch thick. Keeping the slices uniform helps them cook evenly.

3. Arrange and Bake

Spread the potato slices in a single, slightly overlapping layer on the baking sheet. Avoid stacking them too much, as this can prevent them from crisping properly.

Bake for 20–25 minutes, flipping once halfway through, until the edges turn golden and the centers are tender.

4. Prepare the Toppings

While the potatoes bake, cook the bacon until crisp, then drain and crumble it into small pieces. Shred the cheese and slice the green onions.

5. Add Cheese and Bacon

Remove the potatoes from the oven and gently move them closer together to form a more solid layer. Sprinkle the shredded cheddar evenly across the top, followed by the crumbled bacon.

6. Final Bake

Return the pan to the oven for 5–8 minutes, just until the cheese is melted and bubbling.

7. Finish and Serve

Remove from the oven and immediately sprinkle the sliced green onions over the top. Let cool slightly, then serve directly from the pan.

Helpful Tips and Variations

For extra crispiness, you can lightly toss the potato slices with a small amount of oil and seasoning before baking. This helps achieve a golden, crunchy texture.

You can also experiment with different cheeses. An Irish cheddar adds a rich flavor, while combining cheddar with Monterey Jack creates a smooth, melty finish.

If you enjoy a bit of heat, try adding a pinch of red pepper flakes or using a sharper cheese variety. For a heartier option, you can include additional toppings such as finely chopped cooked meat alternatives.

When serving a larger group, consider using two baking sheets and rotating them halfway through cooking to ensure even browning.
