Preheat oven to 450℉. Line a large baking sheet with parchment paper.
Wash/scrub potato then slice into ¼-inch thick rounds using a sharp chef's knife or a mandoline. For crispier chip-like potatoes you can slice them thinner, I like mine to resemble french fries with a fluffy center.
Place sliced potato rounds into a bowl of ice water while you prep the toppings. This little soak (approx. 10 min) helps remove excess starch and helps our potatoes get nice and crispy on the edges.
Measure and prep toppings. Cook 2-3 slices of bacon via preferred method and chop.
Drain potatoes and pat dry on both sides and place in a single layer on baking sheet.
Spray or rub both sides of the potatoes potatoes with oil and sprinkle with paprika, garlic powder, salt, and pepper. For some heat you can add cayenne pepper to the mix.
Cook on the center rack at 450℉ for 15 minutes. Use tongs to flip potatoes and cook on other side for an additional 15 minutes. If potatoes were cut thinner than ¼-inches they will be done sooner.
Remove tray from oven and cover with grated cheese and bacon crumbles. Return to oven for 1-2 minutes to melt cheese.
For casual nachos, you can absolutely eat them right off the baking sheet with all your favorite toppings. For a bit more presentation, arrange nachos on a plate or in a cast iron skillet and top with choice of toppings. Enjoy!
