After perfecting a creamy beer cheese sauce, using it beyond a dip was the next step. Its bold, savory flavor pairs especially well with salty, crunchy snacks like kettle chips. These Irish nachos are a delicious, easy idea: thick chips layered under a warm beer cheese sauce, finished with crisp bacon, diced tomatoes, sliced green onion, and a dollop of sour cream.

There are several ways to build Irish-style nachos using different potato bases—waffle fries, potato wedges, or thin roasted potato slices all work—but the quickest and simplest method is to use sturdy potato chips. Kettle chips or other thick-cut chips stand up best to the sauce and toppings so the final dish keeps a great texture.

Ingredients

  • Beer cheese sauce – Use a homemade beer cheese sauce (recipe provided in the notes below) or prepare it ahead and reheat before assembling the nachos.
  • Potato chips – 4 cups of sturdy kettle-style potato chips or the thickest chips available; original or sea salt flavor is recommended.
  • Bacon – About 6 slices cooked and crumbled (oven-baked or pan-fried), or use real bacon bits. Cook and crumble ahead of time for convenience.
  • Green onions – Diced, for a bright, crunchy finish.
  • Tomatoes – Diced, for juicy freshness.
  • Sour cream – A generous dollop to finish the center of the nachos; you can also serve extra on the side for dipping.

  1. Make the beer cheese sauce. Prepare the sauce on the stove following the notes below. Keep it warm on low heat so it pours smoothly over the chips.
  2. Arrange the chips. Spread the kettle chips in a single overlapping layer on a large plate, cast-iron skillet, or rimmed sheet pan.
  3. Pour the sauce. Spoon or pour the warm beer cheese sauce evenly over the chips so they’re well coated but not completely drowned.
  4. Add toppings. Sprinkle the cooked, crumbled bacon over the sauced chips. Add a central dollop of sour cream and scatter diced green onions and tomatoes on top. Serve immediately so the chips remain crisp.

Recipe variations

If you prefer a different potato base, these easy swaps work well and still let you enjoy the beer cheese flavor.

  • Waffle fries – Use a 22-ounce bag of frozen waffle fries. Bake according to package directions on a large rimmed baking sheet. While fries bake, make the beer cheese sauce. When fries are hot and crispy, pour the sauce over them on the baking sheet and add toppings.
  • Potato wedges or steak-cut fries – Use a 28-ounce bag of frozen wedges or steak fries. Bake until crispy, then top with warm cheese sauce and finish with bacon and fresh toppings.
  • Thinly sliced raw potatoes – Slice 1½ pounds of russet potatoes into 1/4-inch rounds (no need to peel). Toss with 2 tablespoons olive oil and 1 tablespoon fry seasoning (or 1 tsp salt, 1 tsp black pepper, 1 tsp paprika). Arrange in a single layer on a parchment-lined sheet pan and bake 20 minutes, flip, then bake another 20 minutes until crisp. Top with warm cheese sauce and other toppings.

For different flavors, substitute cooked diced corned beef for the bacon, or trade green onions for quick-pickled onions. You can also add classic nacho extras like sliced jalapeños, chopped cilantro, or extra hot sauce to the cheese for heat.

Recipe notes

  • Serve fresh. These nachos are best the moment they’re assembled. Storing and reheating will make chips soggy and diminish texture. Instead, keep extra cheese sauce refrigerated for another round of nachos later.
  • Storing the sauce. Cool the beer cheese sauce, transfer to an airtight container, and refrigerate. Reheat gently on the stove over medium-low for 5–10 minutes, stirring until smooth and hot before using.
  • Alcohol in the sauce. The alcohol cooks off while heating the sauce. If you prefer to avoid alcohol entirely, use nonalcoholic beer in the recipe.
  • Make it spicy. Stir 2–3 teaspoons of your favorite hot sauce into the warm cheese sauce, or add sliced jalapeños on top for a spicy kick.
  • Vegetarian option. Omit the bacon or replace it with a smoky vegetarian bacon alternative to keep the savory flavor without meat.

How to make the beer cheese sauce

  • Grate 1 cup sharp cheddar and 1/2 cup Swiss cheese and set aside.
  • Melt 2 tablespoons butter in a saucepan over medium heat. Whisk in 2 tablespoons flour to form a roux.
  • Slowly whisk in 1/2 cup heavy cream until smooth.
  • Add 1/4 cup beer, 1 tsp Worcestershire sauce, 1/2 tsp Dijon mustard, 1/4 tsp salt, 1/4 tsp garlic powder, 1/4 tsp onion powder, and 1/4 tsp smoked paprika. Bring to a gentle simmer.
  • Reduce heat to low and add the shredded cheeses, stirring constantly until fully melted and the sauce is smooth and creamy. Keep warm until ready to use.
