FAQ

Can I use fresh potatoes instead of frozen hash browns?

Yes, but you'll need to parboil diced potatoes for 5-7 minutes first and drain well to remove excess moisture before mixing with other ingredients.

Can I freeze this casserole?

Yes, assemble without baking, wrap tightly and freeze for up to 3 months. Thaw overnight in refrigerator before baking, adding 10-15 minutes to cook time.

What if I don't have ranch seasoning?

Mix 1/2 teaspoon each of garlic powder, onion powder, and dried dill with 1/4 teaspoon each of salt and black pepper as a substitute.
