Potatoes - I like to use russet potatoes for this recipe and leave the skin on. However, wash and dry the potatoes first as they're probably a little dirty.
Olive oil, rosemary, thyme, salt, and pepper - Toss the sliced potatoes with the olive oil and seasonings before roasting them in the oven.
Shredded cheddar cheese - mild or sharp (I like sharp cheese for this recipe).
Bacon - for easy prep, cook the bacon in the oven according to the package directions. Want meatier nachos? Add ½ pound of cooked ground beef!
Sour cream, pico de gallo, green onions, and cilantro - or use your own favorite nacho toppings. Tip - try the pico de gallo in your grocery store's deli section.
How to Make Them
(1) Preheat your oven to 450F degrees. Spray a large baking sheet with nonstick spray (or use parchment paper).
(2) Place seasoned, sliced potatoes in a single layer on a baking sheet and bake for 20 minutes then flip and bake an additional 20 minutes.
(3) Place the crispy roasted potatoes in a cast iron skillet in a round, overlapping pattern.
(4) Sprinkle the bacon and cheese on top and bake for 3-4 minutes until cheese is melted.
(5) Top with sour cream, pico de gallo, green onion, and cilantro.
(6) Add any additional toppings. Eat, share, love!
Frequently Asked Questions
They probably got their name simply because the recipe uses potatoes and not classic tortilla chips. They certainly did not originate in Ireland lol.
How about some grilled corn on the cob or fresh guacamole? You can also serve these nachos as a side dish with steak, chicken, or ribs.
That's up to the one making the nachos! This version, one single layer overlapping style, is easy enough for anyone to maneuver into their mouth :). One layer also makes it easier to ensure every slice of potato gets its fair share of toppings!
Store leftover in the refrigerator for no more than 3 days. Keep them in an airtight container. Eat them cold or reheat them in the microwave.
Tips and Substitutions
To ensure even and consistent potato slices, use a mandolin. I like this one from OXO - Good Grips. Plus, it's faster and safer than a kitchen knife.
For a stronger cheese flavor, use an extra sharp beer cheese like this one from Wisconsin Cheese Company - Beer Cheddar.
Want more meat? Add ½ pound of cooked corned beef on top of the nachos before baking!
