Instructions
- Preheat oven to 350°F (175°C). Grease a 9×13 inch casserole dish.

- Whisk in the Worcestershire sauce, poultry seasoning, salt, mustard, garlic powder, onion powder, and pepper.
- Bring to a simmer and cook until thickened.
- Remove from heat and whisk in 1 cup of cheddar and Parmesan cheese until smooth.
- Stir in the Greek yogurt and hash browns.
- Transfer the mixture to the prepared casserole dish and top with the remaining cheddar cheese.
- In a small bowl, combine the cornflakes and melted butter. Sprinkle over the casserole.
- Cover with foil and bake for 40 minutes.
- Uncover and bake for an additional 12 minutes.
- Broil for 1-2 minutes to brown the topping.
- Let rest for 10 minutes before serving.
Tips
- Use low sodium chicken broth to prevent the casserole from being too salty.
- Shred your own cheese for the best flavor and texture.
- Pat the hash browns very dry to avoid a soggy casserole.
- If you don’t have Greek yogurt, you can use sour cream instead.
- To make ahead, assemble the casserole up to 2 days in advance and refrigerate. Add the topping before baking.
- You can freeze the casserole, either baked or unbaked, for up to 3 months. Thaw overnight in the refrigerator before baking.
