- 3 whole russet potatoes
- 4 cups vegetable oil, or as needed
- 1 cup shredded Cheddar cheese
- 1 cup shredded Monterey Jack cheese
- 3 slices cooked bacon, chopped
- 12 slices pickled jalapeno pepper, or to taste
- 1/3 cup ranch dressing
- Slice potatoes in wide rectangular slices about 1/4-inch thick and 3/4-inch wide, yielding 12 to 15 slices per potato. Keep potatoes in cold ice-water bath until ready to fry.
- Heat oil in a deep-fryer or large saucepan to 350 degrees F (175 degrees C).
- Set oven rack about 6 inches from the heat source and preheat the oven's broiler.
- Dry potato slices on paper towels.
- Fry potatoes in hot oil for 1 minute; remove from oil, drain, and set aside to cool for about 10 minutes. Return potatoes to oil and fry until golden brown, about 5 minutes more. Again, remove from oil and drain briefly on paper towels.
- Spread potatoes onto a baking sheet; top with Cheddar cheese, Monterey Jack cheese, and bacon.
- Heat the fries under the broiler until the cheese melts, 3 to 5 minutes. Top with jalapeno peppers to serve with ranch for dipping.
