If you prefer a creamier texture, mix in a bit of sour cream with the mushroom soup. Always taste and adjust seasoning as needed, especially when using low-sodium products.

Frequently Asked Questions

Can I prepare this casserole in advance?

Yes, you can prepare the casserole up to the baking step. Cover it tightly and refrigerate for up to 24 hours. When ready to bake, simply add an additional 10-15 minutes to the baking time to ensure it heats through properly.

What can I use instead of mushroom soup?
