Ingredients

Instructions

  • Preheat oven to 350 degrees then coat an 8" square casserole dish with cooking spray.
  • Rinse, peel and slice each potato into ¼" thick slices. Next, slice the onion as thinly as possible. Place it, along with the sliced potatoes and salt, in a large pot and add enough water to cover by 1". Place the pot over high heat, bring to a boil then immediately reduce the heat to medium-low. Simmer gently until the potatoes are cooked through but still firm—approximately 5–10 minutes.
  • While the potatoes and onions are simmering, melt butter in a large skillet over medium heat. Whisk in flour and cook for 1 minute, stirring constantly. Pour in chicken broth, whisk until smooth then stir in milk, garlic powder, ½ tsp salt, pepper and both cans of green chilies. Bring the mixture to a bubble, reduce heat to medium-low and simmer for 6 minutes, stirring frequently.
  • Remove the skillet from heat, stir in both cheeses then transfer sauce to a large bowl and set aside. Drain potatoes and onions into a colander then add them to the cheese mixture. Gently stir until each potato slice is coated in the sauce. Taste and season with salt and pepper if needed.
  • Transfer mixture to the prepared casserole dish and bake uncovered for 15 minutes. Make sure to place the casserole dish on a baking sheet if your pan is really full. Remove from oven, top with approximately ½ cup cheddar cheese then return to oven for an additional10−15 minutes. Remove casserole and allow it to rest 10-15 minutes before serving.

Notes

Place the potatoes in a bowl of cold water as you peel and slice them—this will prevent them from oxidizing and turning brown.
