Key Culinary Techniques & Science
Understanding these principles ensures the best results:
- Thawed Hashbrowns: Frozen hashbrowns release excess water when baked, leading to sogginess. Thaw and drain them first.
- Creamy Binder: A mix of cream of chicken soup (or substitute), sour cream, and melted butter keeps the casserole moist without being greasy.
- Layered Cheese: Sharp cheddar adds depth, while a Parmesan breadcrumb topping creates a crispy contrast.
- Resting Time: Let the casserole sit 5-10 minutes after baking for cleaner slices.
Ingredients & Substitutions
For the Casserole Base
- 1 (30 oz) bag frozen shredded hashbrowns, thawed and squeezed dry (sub: fresh grated potatoes, parboiled for 2 mins)

- 1 cup (240g) sour cream (sub: plain Greek yogurt)

For the Cheese Layer
