How to Make Irish Nachos

1. Preheat the Oven

Preheat oven to 425°F (220°C) and line a large baking sheet with foil.

2. Slice the Potatoes

Scrub and dry the potatoes, then slice into thin rounds (about ⅛–¼ inch thick) for even cooking.

While potatoes bake, cook bacon until crisp, then crumble. Shred cheese and slice green onions.

5. Add Cheese and Bacon

Remove potatoes from oven and gently push them closer together. Sprinkle evenly with cheddar cheese and bacon.

6. Melt and Finish

Return to oven for 5–8 minutes until cheese is melted and bubbly.

7. Garnish and Serve

Top with green onions and let cool slightly before serving straight from the pan.
