This copycat hash brown casserole is an incredibly comforting side dish you'll want to make for both breakfast spreads and dinner parties alike. We opted to ditch the canned creamed soup and make a homemade cheese sauce instead. The result is a homey rendition of the classic Cracker Barrel dish.
For an elevated flavor profile, consider using sharp Cheddar instead of mild, or a blend with Gruyere for nuttier notes. Ensure your hash browns are fully thawed and patted dry to prevent a watery casserole; excess moisture can hinder crispness. When making the roux, cook the flour until it's a light golden color and smells nutty, but be careful not to burn it, as this will impart a bitter taste. The final high-temperature bake is crucial for achieving that signature crispy, browned top, so don't rush this step. For an extra layer of flavor, a pinch of smoked paprika can be added to the cheese sauce. Season generously with salt and pepper at each stage to build flavor.
