Ingredients You’ll Need
This easy chicken spaghetti casserole uses simple pantry staples that come together into something truly delicious.
- Spaghetti
This is the base of the casserole and holds everything together. Breaking it in half makes it easier to mix and serve. - Rotisserie chicken
A major shortcut that adds flavor and saves time. I like using a mix of white and dark meat for the best texture. - Cream of chicken soup
This creates that creamy, comforting base. You can also use cream of mushroom or cream of celery if needed. - Rotel (diced tomatoes with green chilies)
Adds a little kick and extra flavor. If you prefer less spice, you can use mild or substitute with plain diced tomatoes. - Cream cheese
Makes the sauce extra rich and creamy. Make sure it is softened so it blends smoothly. - Sour cream
Adds tang and helps balance the richness of the cheese. - Chicken broth
Thins the sauce slightly so everything mixes evenly. - Cheddar cheese
Melts into the casserole and creates that cheesy top layer. You can swap with Colby Jack or a Mexican blend. - Garlic powder
Adds depth of flavor without extra prep. - Onion powder
Brings in that savory note that ties everything together. - Salt and black pepper
Simple seasonings that enhance all the flavors.

How to Make Rotisserie Chicken Spaghetti Casserole
This creamy chicken spaghetti bake comes together quickly with just a few simple steps.

Pro Tips for the Best Chicken Spaghetti Casserole
- Let the cream cheese soften fully so your sauce mixes smoothly without lumps
- Do not overcook the pasta since it will continue cooking in the oven I always mix everything in a really large bowl to avoid spilling and to get an even coating
- One trick that works in my kitchen is adding a splash more chicken broth if the mixture feels thick before baking
- Let it rest before serving so it sets up and slices easier
What to Serve With Rotisserie Chicken Spaghetti
This rotisserie chicken pasta bake is a complete meal, but I love pairing it with a few simple sides.

- Steamed broccoli or green beans

It is also perfect for meal prepping or serving at potlucks.

You can easily customize this easy chicken spaghetti casserole to fit your taste.
- Make it spicy by using hot Rotel or adding a pinch of cayenne
