common recipe questions
Can I use a different type of cheese?
Yes, you can use any melting cheese like mozzarella, Gouda, or a mix of your favorites.
What can I substitute for sour cream or yogurt?
You can use cream cheese, mascarpone, or a dairy-free alternative for a similar creamy texture.
Is it necessary to refrigerate the casserole before baking?
Refrigerating helps the flavors meld and the casserole to set, but you can bake it immediately if short on time. The texture may be more runny, however.
Can I add other ingredients to the casserole?
Yes, you can add ingredients like bacon bits, chives, or garlic.
How do I know when the potatoes are fully cooked?
The potatoes are done when they are tender enough to be easily pierced with a fork.
What can I use instead of onion salt?

Can I prepare this casserole ahead of time?

Can I freeze this casserole?
