Easy cheesy potato casserole with a homemade cheese sauce that's better than store-bought. Ultimate comfort food!
Ingredients:
  • 1/4 cup butter, plus more for the casserole dish
  • 1 yellow onion, diced
  • 3 cloves garlic, minced
  • 1/4 cup all-purpose flour
  • 3 cups vegetable or chicken stock
  • 2 cups grated cheddar cheese
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 30 ounces frozen hash browns
  • DAD ADD: Fried Serrano Rings:
  • 3 serrano peppers, sliced
  • 2 tablespoons olive oil
  • Coarse salt
Instructions:
  • Preheat the oven to 400°F and lightly butter or grease a 9x13-inch baking dish.
  • Create a decadent cheese sauce by melting 1/4 cup of butter in a medium pot over medium heat. Sauté diced onions until translucent, then add minced garlic for 30 seconds. Sprinkle in flour and cook until it reaches a tan hue. Gradually pour in stock, simmering until the sauce thickens like gravy. Finish by melting in cheddar cheese, seasoning with salt and pepper, and then remove from heat.
  • Mix the frozen hash browns with the sauce in a large bowl until well combined. Transfer the mixture to the baking dish and smooth the top.
  • For a perfectly crispy casserole: Bake at 400°F for 45 minutes on the center rack, then broil on high for 5 minutes to crisp up the top. If your dish isn't broiler-safe, increase the oven temperature to 500°F and bake for an additional 3 minutes.
  • Serve: Allow the casserole to cool for a bit, then enjoy while still warm.
  • For the crispy serrano rings, slice serrano peppers into thin coins and cook in olive oil over medium heat until browned, about 2-3 minutes. Drain on a paper towel and season with a pinch of salt.
