Irish Nachos Recipe

Loaded Irish nachos are one of those snacks I can never walk away from once the pan hits the table. There’s something about that mix of crispy edges, melted cheddar, salty bacon, and cool sour cream that’s simply irresistible. They’re warm, messy, and exactly what you expect when you’re craving nachos.

These nachos may not be truly Irish in the traditional sense, but the potatoes give them a pub style vibe people love. They’re easy to make and honestly, you can go crazy with extra toppings or stick with the classics I use in this recipe. Whether it’s Saint Patrick’s Day or a Saturday afternoon, they pair perfectly with a cold drink (or beer) and good company.

If you’re creating the ultimate party spread, pair these Irish nachos with a batch of my Hot Honey Chicken Wings and Baked Jalapeno Poppers.

How to Make Irish Potato Nachos

Step 1. Preheat the oven to 435°F and line a baking sheet with parchment paper.

Step 2. Place thinly sliced russet potatoes in a large bowl and toss with olive oil, salt, pepper, and garlic powder until coated.

Step 3. Arrange the potato slices in a single layer on a baking sheet.

Step 7. Broil for 3 to 5 minutes until the cheese is fully melted and lightly bubbling.

Step 8. Remove from the oven and top with sour cream, diced tomato, and green onions. Serve immediately.

Storage Instructions

Store leftovers in an airtight container for up to 2 days. You can reheat them in the oven at 375°F until warmed through and the cheese melts again.

Freezing is not recommended since the potato slices lose their crisp texture after thawing.

Variations And Add-ins

  • Corned beef: Add shredded corned beef for a hearty Irish pub style topping.
  • Heat: Sprinkle sliced jalapeno or drizzle salsa for extra heat.
  • Ground meat: Swap bacon for cooked ground beef or sausage to create a loaded dinner style nacho platter.
  • Shredded meat: Add some Shredded Beef or Shredded Chicken over the top.
  • Cheese: Mix cheddar with mozzarella for an extra melty cheesy goodness.

Tips And Tricks

  • Slice the russet potatoes thinly with a kitchen mandolin if you have one. It helps keep the thickness of the slices the same.
  • Keep the sliced potatoes in a single layer on the baking sheet so they roast instead of steam.
  • Watch closely under the broiler because melted cheese can go from bubbly to burnt very quickly.
  • Use freshly shredded cheddar cheese instead of pre-shredded so the cheese melts smoother and more evenly.
  • Serve immediately for the best crispy texture since potato nachos soften as they cool.

FAQs

Do I have to peel the potatoes?

You do not need to peel them first. Just make sure you give them a good scrub before slicing.

Why aren’t my potatoes crispy?

They’re probably sliced too thick or overcrowded on the pan. Be sure to give them space.

Can I prep these ahead of time?

You can slice the potatoes a few hours ahead and keep them in cold water. Dry them well before baking.
