Southern Chicken Spaghetti
Y‘all, this is the one I bring when there are twelve people to feed and I have forty-five minutes. Southern Chicken Spaghetti has never once let me down in that situation. One pan, feeds a crowd, comes out of the oven with cheese bubbling on top, and every person at the table goes back for seconds before anyone’s finished first.
Tender chicken, spaghetti, a creamy Rotel sauce baked under a layer of melted cheese. This is Southern potluck royalty and it’s earned that status. Church potluck. Neighborhood gathering. The casserole people request by name at my house.
This is the casserole that has cleared every table I’ve put it on. I’ve watched from across the fellowship hall. It goes before the green bean casserole. It goes before the deviled eggs. It’s that reliably popular, and I’ve tested it on enough crowds to say that with confidence.
This one has a reputation on my street. And on my block. And at my church. Three different venues and the same result every time.
Why This Recipe Works
Rotel tomatoes — diced tomatoes with green chilies — are the flavor foundation that makes this casserole distinctly Southern. They add a mild heat and acidity that cuts through the cream sauce and keeps the whole thing from being heavy. Without Rotel, you have a creamy pasta bake. With Rotel, you have chicken spaghetti.
Cream cheese in the sauce creates a richness that’s different from a flour-based roux. It also emulsifies the Rotel’s acidity into a silky, cohesive sauce that doesn’t separate in the oven. This is the component most home cooks don’t expect to see in a casserole and the one that makes this version better than others.
Cooking the spaghetti in chicken broth instead of plain water adds flavor at the pasta level, so every part of the casserole is seasoned rather than just the sauce layer on top.
Ingredients
Chicken Spaghetti
- 12 oz spaghetti, broken in thirds
- 4 cups chicken broth
- 3 cups cooked shredded chicken (rotisserie works perfectly)
- 1 (10 oz) can Rotel tomatoes with chilies
- 1 (10.5 oz) can cream of mushroom soup
- 8 oz cream cheese, softened and cubed
- 1 cup chicken broth
- 1 cup sour cream
- 1 tsp garlic powder
- 1 tsp onion powder
- Salt and pepper to taste
- 2 cups shredded colby jack or cheddar cheese
How to Make It
1
1 Cook Spaghetti in Broth
Bring 4 cups chicken broth to a boil in a large pot. Cook spaghetti according to package directions, using the broth instead of water. Drain, reserving ½ cup cooking liquid. This is the step. Everything else is just assembly.

2 Make the Sauce
Preheat oven to 350°F. In a large bowl, combine Rotel tomatoes, cream of mushroom soup, cream cheese cubes, 1 cup broth, sour cream, garlic powder, onion powder, salt, and pepper. Stir until the cream cheese is mostly blended (a few lumps are fine).

3 Combine
Add drained spaghetti and shredded chicken to the sauce. Toss to combine. If the mixture seems too thick, add a little of the reserved pasta water. Pour into a greased 9×13 baking dish.

4 Top and Bake
Top generously with shredded cheese. Bake 25 to 30 minutes until bubbling around the edges and the cheese is golden and melted. Let rest 5 minutes before serving.
Things I’ve Learned From Making This Too Many Times to Count
Cook the spaghetti in chicken broth. This small change flavors the pasta from within and means the whole dish is seasoned, not just the sauce coating it. It uses one extra pot but it’s worth it.
Soften the cream cheese before adding. Cold cream cheese in the sauce leaves lumps. Room temperature cream cheese blends into the sauce completely. Take it out of the refrigerator 30 minutes before you need it.
Don’t overbake. The casserole should be bubbling and the cheese should be melted and golden, not dried out. 30 minutes is the max. Pull it when it’s bubbling and the cheese is set.
This feeds twelve comfortably. I have made this for twelve people and forty-five minutes of prep. That’s the crowd-to-effort ratio that makes this casserole worth knowing about.
The church potluck pan comes back clean every time. I’ve been bringing this to potlucks for four years. The pan has never once come home with anything left in it. That is the benchmark I use.
What to Serve With Southern Chicken Spaghetti
Serve with a simple green salad and Cast Iron Skillet Cornbread for a complete Southern comfort dinner. For the full potluck approach, this pairs perfectly with Classic Southern Coleslaw and Southern Baked Mac and Cheese on a church fellowship hall table.
Variations Worth Trying
Spicier Version: Use hot Rotel instead of original, and add ½ tsp cayenne to the sauce. Good for crowds that like heat.
With Green Pepper and Onion: Sauté ½ cup diced green pepper and ½ cup diced onion in butter before adding to the sauce. Adds vegetable texture and more savory depth.
With Velveeta: The original version of this casserole uses Velveeta instead of cream cheese. Cut 8 oz Velveeta into cubes and melt into the sauce. Different texture, just as crowd-pleasing, very traditional.
Angel Hair Version: Use angel hair pasta instead of spaghetti. Shorter cook time, slightly different texture, works well for smaller dishes. Use what you’ve got — this recipe has manners, it won’t fuss.
Storage and Reheating
Refrigerate covered for up to 4 days. Reheat at 350°F covered for 20 minutes, or microwave individual portions for 2 to 3 minutes. The casserole reheats very well — the sauce loosens with the heat and coats the pasta again. Freeze for up to 2 months, assembled but unbaked. Thaw overnight and bake as directed.
FAQ
Can I substitute cream of chicken soup for cream of mushroom?
Yes — either works and some people prefer cream of chicken for a cleaner flavor. The mushroom soup adds a slightly earthier depth, but the casserole is excellent with either. Use what you have on hand.
Can I make this ahead?
Yes. Assemble completely, cover, and refrigerate up to 24 hours. Bake from cold, adding 10 minutes to the covered bake time. Do not freeze after baking — the pasta texture changes. Freeze assembled and unbaked for best results.
Can I use spaghetti noodles or does it need to be broken?
Break them in thirds before cooking. Full-length spaghetti is impossible to toss into a casserole and serve cleanly. Broken thirds give you casserole-sized noodles that coat in the sauce evenly and serve with a fork or spoon without the full-length pasta tangling problem.
