Confetti Chicken Spaghetti Casserole

Jenny Powers


This is such a colorful and tasty recipe. Whenever I make this, folks always ask for the recipe. Sooo good. This picture was taken before I added shredded cheddar cheese on the top and baked. I just wanted you to be able to see the ingredients.

Oh my, this is not your normal marinara-based spaghetti casserole. The Rotel cheese sauce mixed with the delicious vegetables and spaghetti makes this dish special. It's cheesy with a bit of heat. We love all the colorful and crunchy vegetables in the casserole. This is great for a weekly dinner or a potluck. Serve with garlic bread and a fresh salad for a delicious meal.
