Why You’ll Love This Recipe

Irish Nachos combine everything people love about loaded potato skins and classic nachos into one easy-to-share dish. Thin potato slices become wonderfully crisp in the oven, while melted cheddar cheese creates a gooey layer that holds everything together. Crispy bacon adds a smoky crunch, and fresh green onions provide a bright finish that balances the richness.

With only four ingredients, this recipe delivers maximum flavor with minimal effort.

Ingredients

• 3 large russet potatoes
• 2 cups shredded sharp cheddar cheese
• 8 slices bacon, cooked and crumbled
• 3 green onions, thinly sliced

Optional Garnishes

Although the basic recipe only uses four ingredients, you can serve the nachos with:

• Sour cream
• Ranch dressing
• Salsa
• Guacamole
• Pickled jalapeños
• Hot sauce
• Fresh parsley

Step 1: Prepare the Potatoes

Wash the potatoes thoroughly under cold running water.

Since the skins become crispy during baking, there’s no need to peel them. Simply scrub away any dirt and pat them dry with paper towels.

Using a sharp knife or mandoline slicer, cut the potatoes into slices about ¼ inch thick. Keeping the slices uniform ensures they cook evenly.

If using a mandoline, always use the safety guard to protect your fingers.

Step 2: Remove Excess Starch

Place the potato slices into a large bowl of cold water.

Allow them to soak for 20 to 30 minutes.

This step removes excess starch, helping the potatoes become crispier during baking.

After soaking, drain the potatoes thoroughly.

Pat every slice completely dry with clean kitchen towels or paper towels. Moisture prevents crisping, so drying them well is important.

Step 3: Arrange the Potatoes

Preheat your oven to 425°F (220°C).

Lightly grease a large baking sheet or line it with parchment paper.

Arrange the potato slices in a single layer.

Avoid overlapping the slices because crowded potatoes will steam instead of becoming crispy.

Step 4: Bake Until Crispy

Bake the potatoes for 18 minutes.

Carefully flip each slice using tongs or a spatula.

Return them to the oven and bake for another 15 to 20 minutes, or until both sides are golden brown with crispy edges.

The centers should remain tender while the outside develops a delicious crunch.
