Ingredients
(Large rimmed baking sheet; serves 4–6)
2 lbs russet potatoes, scrubbed clean
8 oz sharp cheddar cheese, freshly shredded
6 slices thick-cut bacon, cooked until crisp
3 green onions, thinly sliced
Optional: Light cooking spray or olive oil, flaky sea salt, sour cream, or hot sauce for serving
Step-by-Step Instructions
Preheat & Prep: Set your oven to 425°F (220°C). Line a large rimmed baking sheet with aluminum foil and lightly coat with nonstick spray or a thin film of oil for easy cleanup and crisp edges.
Slice & Dry: Pat the scrubbed potatoes completely dry. Leaving the skins on, slice them into 1/8–1/4 inch rounds. Aim for consistent thickness so every slice cooks evenly.
First Bake: Arrange the potato slices in a single, slightly overlapping layer on the prepared sheet. Avoid stacking them high, which traps steam. Bake on the middle rack for 20–25 minutes, flipping once halfway through, until the edges are golden and the centers are fork-tender.
Prep the Toppings: While the potatoes bake, cook the bacon in a skillet over medium heat until crisp. Transfer to a paper towel–lined plate to drain, then crumble into small pieces. Shred the cheddar and thinly slice the green onions.
Assemble & Melt: Remove the potatoes from the oven. Gently nudge the slices closer together to minimize gaps, creating a cohesive “chip” base. Sprinkle the shredded cheddar evenly over the hot potatoes, covering as much surface area as possible. Scatter the crumbled bacon over the cheese.
Final Bake & Finish: Return the pan to the oven for 5–8 minutes, just until the cheese is fully melted, bubbling, and the bacon sizzles. Remove from the oven and immediately sprinkle with sliced green onions for freshness and color.
Rest & Serve: Let the Irish nachos cool for 3–5 minutes so the cheese sets slightly and scooping stays clean. Serve warm directly from the pan, using a spatula to lift generous portions of potatoes, cheese, and bacon.

You Must Know
Dry potatoes thoroughly: Excess moisture creates steam instead of crisp edges. Pat them completely dry before baking.
Consistent thickness is key: Uneven slices lead to uneven cooking. A mandoline guarantees precision, but a sharp knife and steady hand work just as well.
Leave space for airflow: Overcrowding the pan during the first bake causes soggy centers. A single, slightly overlapping layer ensures proper browning.
Shred your own cheese: Pre-shredded varieties contain anti-caking cellulose that prevents smooth, even melting.
Don’t skip the rest: Cutting in immediately causes the cheese to slide off. A brief 3–5 minute cool-down lets everything set cleanly.
Storage Tips
Refrigerator: Cool completely and store in an airtight container for up to 2–3 days. The potatoes will naturally soften over time.
Reheating: Restore crispness in a 375°F oven or air fryer for 8–10 minutes. Avoid the microwave, which traps moisture and turns the potatoes soggy.
Freezing: Not recommended. Cooked potatoes and dairy-based cheese tend to become grainy and release water when thawed.
Make-ahead note: You can slice and par-bake the potatoes ahead of time, but assemble and melt the cheese just before serving for optimal texture.
Frequently Asked Questions
Can I use a different type of potato?
Yes. Yukon Gold potatoes work well for a creamier interior, though they won’t get quite as crisp as russets. Avoid waxy varieties like red or fingerling potatoes, which hold too much moisture.
Can I prep this ahead of time?
You can slice the potatoes and store them submerged in cold water for up to 24 hours to prevent browning. Drain and pat completely dry before baking. Assemble toppings and melt the cheese just before serving.
How do I make this vegetarian?
Swap the bacon for smoked paprika-roasted chickpeas, crumbled tempeh bacon, or mushroom “bacon.” Use vegetarian-friendly cheese if needed.
Why aren’t my potatoes getting crispy?
This usually happens from excess moisture, uneven slicing, or overcrowding the pan. Ensure they’re fully dried, slice uniformly, and leave enough space for steam to escape during the first bake.
Can I add extra toppings?
Absolutely. Diced tomatoes, black olives, jalapeños, or a drizzle of hot honey work beautifully. Add delicate toppings after baking to preserve their freshness.
