Cheesy Hashbrown Casserole

Instructions

1. Preheat and Prep:
   Preheat oven to 350°F (175°C). Grease a 9×13 inch casserole dish generously.

2. Sauté the Aromatics:
   In a medium pot over medium heat, heat olive oil. Sauté diced onions until golden. Add minced garlic and cook until fragrant.

3. Craft the Roux:
   Stir in flour to form a roux. Slowly whisk in chicken stock and milk until smooth and velvety, without lumps.

4. Embrace the Cheese:
   Add sour cream and shredded cheddar cheese. Season with salt and pepper. Stir until cheese melts and sauce is creamy.

5. Unite and Bake:
   In a large bowl, mix thawed hash browns with the cheese sauce evenly. Transfer to casserole dish and spread evenly. Top with remaining shredded cheddar cheese.
   Bake for 35-40 minutes, until bubbly and golden on the edges.
