Servings 15


  • 2 pounds frozen GF hash browns thawed
  • 1 tablespoon oil
  • 1 cup onion diced
  • 1/2 large Red pepper diced
  • 1/4 cup butter
  • 1/4 cup cornstarch
  • 2 cups milk
  • 1 cup GF chicken broth
  • 1-1/2 cups shredded Cheddar cheese divided
  • 1-1/2 cups shredded Monterey Jack cheese divided
  • 1 cup sour cream
  • 3/4 teaspoon Salt
  • 1/2 teaspoon ground black pepper
  • 1/2 teaspoon garlic powder


  • Preheat oven to 375 F. Lightly grease a 9x13-inch baking pan. Set aside.
  • Place the thawed hash browns in large mixing bowl.
  • In a large skillet, heat oil over medium heat. Add onions and red pepper and cook until tender (5-8 minutes). Add onion/pepper mixture to hash browns.
  • In a medium saucepan over medium heat, melt butter. Once it starts to bubble, whisk in cornstarch and cook for 1 minute. Increase heat to medium-high and add milk and chicken broth. Continue whisking as it comes to a boil and thickens.
  • Remove from heat and stir in 3/4 cup of each cheese. Once it has melted and incorporated, stir in sour cream, salt, pepper and garlic powder. Pour over potato mixture and stir to combine.
  • Pour into prepared baking pan, cover with foil and bake 45-50 minutes or until bubbling throughout. Remove foil and top with remaining cheese. Bake for another 15 minutes or until golden brown and bubbly. Let sit for 10 minutes and serve.
