Creamy Chicken Spaghetti (Old Fashioned Recipe)

Creamy Chicken Spaghetti is a comforting, family-favorite dinner that comes together quickly with simple pantry ingredients. This creamy, cheesy casserole is packed with flavor and perfect for busy weeknights, potlucks, or feeding a crowd.
Using rotisserie chicken makes this recipe especially easy, but cooked and shredded chicken breasts work just as well. This dish is flexible too—you can use whatever “cream of” soup you have on hand.
I have made this recipe for large family gatherings as well as a smaller version for just the two of us. It can even be assembled a day ahead, making dinner time stress-free.
Serve this Creamy Chicken Spaghetti with a loaf of crusty bread and a fresh salad for a complete meal your family will love.

Looks great can you tell me what you can use instead of mushroom soup due to allergy? Thanks
Is it the mushrooms that you have the allergy to? How about cream of chicken soup..or any creamy soup like this would work.
