Instructions

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with butter or non-stick spray.
In a large bowl, combine thawed hashbrowns, diced tomatoes, and chopped onion. Stir gently to distribute evenly.
Add minced garlic and chopped basil to the mixture and fold in carefully to preserve the texture of the hashbrowns.
Stir in 1 1/2 cups of cheddar cheese and all of the mozzarella cheese. Reserve 1/2 cup of cheddar for the topping. Mix gently until combined.
In a separate bowl, whisk together sour cream, mayonnaise, and milk. Season with salt, black pepper, paprika, and optional red pepper flakes. Pour over the hashbrown mixture and fold until coated evenly.
Transfer the mixture to the prepared baking dish and spread evenly. Sprinkle the reserved 1/2 cup cheddar cheese on top for a golden crust.
Bake in the preheated oven for 45-50 minutes, until the top is golden brown and the edges are bubbling.
Remove from the oven and let cool for 5-10 minutes before serving.
Optional: Garnish with additional chopped basil or a sprinkle of paprika for added color and freshness.

Notes

Thaw hashbrowns completely to avoid excess water in the casserole.
You can assemble the casserole a day in advance and refrigerate until ready to bake.
For extra flavor, try mixing in additional vegetables like bell peppers or spinach.
Leftovers can be stored in an airtight container in the fridge for up to 3 days and reheated in the oven for best results.
