  • 2 large Russet potatoes peeled and diced (1 inch dice)
  • 1 Tbsp baking soda
  • 1 Tbsp kosher salt
  • 2 Tbsp unsalted butter melted
  • 2 Tbsp vegetable oil
  • 1 tsp cumin
  • ½ tsp garlic powder
  • 8 oz Velveeta cheese
  • 2-3 Tbsp pickling brine from a jar of jalapenos plus additional to adjust consistency
  • additional toppings: reduced fat sour cream, chopped green onion


  • Heat oven to 450°F.
  • Put the potatoes in a pot and cover with water to an inch over the potatoes. Add the baking soda and salt.
  • Cover pot and bring to a boil. Uncover, reduce heat, and simmer 4-5 minutes (potatoes should not be cooked all the way). Drain potatoes well.
  • In a mixing boil, combine the butter, oil, cumin, and garlic powder. Add the par-boiled potatoes and gently toss to coat (a rubber spatula helps to not break up the potatoes).
  • Spread the potatoes in a single layer on a rimmed bake dish. Bake at 450°F for 10 minutes, gently give the potatoes a turn with a spatula, and bake an additional 10-15 minutes or until potatoes are cooked through and toasty crispy.
  • While potatoes are cooking, prepare the nacho sauce. Put the Velveeta and jalapeno brine in a saucepan and heat on low heat until melty smooth.
  • Serve the potatoes topped with nacho sauce, sour cream, and green onion.


Water with baking soda added will make a thick, bubbly film on top that can boil up and out of the pot, depending on the size pot you are using. This is why it is better to choose a larger pot and not add too much water. If it does bubble up too much, simply skim it off.
Serving size is for a side dish. This recipe can be easily scaled up to feed more people or for larger servings.
