Oven Baked 4-Ingredient Irish Nachos: The Potluck Dish That Disappears in Minutes

 

Oven‑Baked 4‑Ingredient Irish Nachos

My Irish neighbor brought these to a potluck, and the pan was licked clean in minutes. With just four ingredients, they’re the kind of dish that disappears before you even set it down. Thinly sliced potatoes stand in for tortilla chips, giving you crispy edges, gooey cheese, and smoky bacon—all on one sheet pan.

Why These Irish Nachos Work

• Just 4 ingredients – Potatoes, cheese, bacon, green onions

• One sheet pan – Minimal cleanup, maximum satisfaction

• Crispy potato base – Heartier than tortilla chips

• Ready in under an hour – Perfect for game day or potlucks

• Endlessly customizable – Add your favorite toppings

Ingredients

Ingredient	Amount	Notes
Russet potatoes	4 large (about 2½ lbs)	Thinly sliced
Sharp cheddar cheese	2 cups	Shredded
Bacon	8 slices	Cooked and crumbled
Green onions	4–5	Thinly sliced

Optional for serving

• Sour cream or plain Greek yogurt

• Hot sauce or grainy mustard

• Fresh parsley, chopped

Instructions

1. Preheat and prep
   Preheat oven to 425°F (220°C). Line a large baking sheet with aluminum foil and lightly grease the foil.

2. Slice the potatoes
   Wash the potatoes (peeling is optional). Using a mandoline or sharp knife, slice into ⅛‑inch rounds for even cooking.

3. Arrange on baking sheet
   Spread the potato slices in a single layer on the prepared sheet. They can overlap slightly, but avoid stacking.

4. First bake
   Bake for 20–25 minutes, until the potatoes are tender and edges are starting to crisp.

5. Add toppings
   Remove from oven. Sprinkle shredded cheddar and crumbled bacon evenly over the potatoes.

6. Second bake
   Return to oven and bake for 8–10 minutes, until the cheese is melted and bubbly.

7. Garnish and serve
   Top with green onions (and parsley if using). Serve hot with sour cream and hot sauce on the side.

Pro Tips

• Use a mandoline for thin, uniform slices—this ensures even cooking.

• Keep potatoes mostly in a single layer to avoid steaming.

• Sharp cheddar delivers more flavor; feel free to mix in Monterey Jack or provolone.

• Cook bacon until crispy so it crumbles easily.

• Add toppings after the first bake so the potatoes crisp up before the cheese melts.

• Serve immediately while the cheese is still stretchy.

Variations

• Loaded: Top with sour cream, pickled jalapeños, and a drizzle of ranch.

• Corned beef: Swap bacon for chopped corned beef for an authentic Irish twist.

• Spicy: Add pickled jalapeños and a sprinkle of red pepper flakes.

• Garlic lover: Toss potato slices with minced garlic and olive oil before baking.

• Cheese blend: Use a mix of cheddar, provolone, or pepper jack.
