Tips
- Crispier potatoes: For even crispier potatoes, make sure to spread them out evenly on the baking sheet and allow space between the potatoes for air circulation.
- Make ahead: You can season and cook the potatoes in advance and store them in the fridge. Reheat in the oven to restore their crispiness before adding the cheese sauce.
- Adjust the heat: If you prefer less heat, reduce the amount of jalapeño brine and cayenne pepper in the cheese sauce.
Variations and Substitutions
- Vegan version: Use dairy-free cheese and vegan butter for a plant-based version of this dish.
- Spicy option: For an extra kick, add more pickled jalapeños to the cheese sauce or sprinkle chopped fresh jalapeños on top of the finished dish.
- Cheese alternatives: If you don’t have Cheez Whiz, you can use melted cheddar cheese or a store-bought nacho cheese dip.
- Different potatoes: While white potatoes work best for this recipe, you can substitute with red potatoes or sweet potatoes for a slightly different texture and flavor.
FAQs
- Can I make these potatoes ahead of time? Yes, you can cook and season the potatoes in advance. Just reheat them in the oven to regain their crispy texture before adding the nacho cheese.
- Can I use frozen potatoes? Fresh potatoes are recommended for this recipe, but if you use frozen, be sure to adjust cooking times for crispness.
- How can I store leftovers? Leftover potatoes can be stored in an airtight container in the fridge for up to 3 days. Reheat in the oven to keep them crispy.
