Why you’ll love this recipe

• Speedy prep: Most of the heavy lifting is already done if you use cooked chicken, so you can be on the table fast.
• Big on flavor: Sharp cheddar and Rotel bring tang and depth, while cream cheese gives the sauce a silky texture.
• Comfort food with a twist: Spaghetti is dressed up with Tex-Mex-style diced tomatoes and chiles for an inviting fusion of flavors.
• Flexible: Use leftover chicken or a store-bought rotisserie bird and the recipe still shines.

Ingredients

• 16 ounces spaghetti, cooked and drained
• 5 cups chopped cooked chicken, leftovers or rotisserie
• 30 ounces Rotel tomatoes and chiles (3 cans)
• 8 ounces cream cheese, softened
• 8 ounces shredded sharp cheddar cheese
• 1 bunch scallions, chopped
• 1 tablespoon chicken base or 3 bouillon cubes
• ½ teaspoon garlic powder
• ¾ cup crushed Ritz crackers (optional)

Notes on ingredients and prep

You’ll want the cream cheese at room temperature so it blends smoothly into the sauce. If you’re using whole rotisserie chicken, remove the skin and shred the meat before measuring five cups of chopped cooked chicken. For the chicken base option, dissolve it in a little warm water or stir it in directly—either works. If you prefer a crisp topping, the crushed Ritz crackers get sprinkled over the top before serving or briefly broiled for a golden finish.

Leave the pasta slightly undercooked in the boiling water if you plan to bake the assembled dish for a short time, but if you’re serving it straight from the stove, cook to package directions and drain well.

Cheesy Chicken Spaghetti with Rotel — Step-by-step

The following directions are rewritten into clear, numbered steps so you can follow along easily. They keep the same order and ingredient amounts as listed above and make the process feel effortless.

1. Bring a large pot of salted water to a boil. Add the 16 ounces of spaghetti and cook according to package directions until al dente. Drain the spaghetti thoroughly and set it aside in the pot or a large bowl.
2. While the pasta cooks, prepare the chicken. If you’re using a rotisserie bird, remove the skin and bones and chop the cooked meat into bite-sized pieces until you have 5 cups of chopped cooked chicken. If using leftovers, chop them to the same size for even distribution.
3. Open the three 10-ounce cans of Rotel tomatoes and chiles and pour the entire 30 ounces into a medium saucepan over medium heat. Warm the tomatoes until they begin to simmer, stirring occasionally.
4. Add the 8 ounces of softened cream cheese to the saucepan with the Rotel. Stir continuously until the cream cheese melts completely and forms a smooth, slightly thickened sauce. Lower the heat if needed to prevent scorching.
5. Stir in the 8 ounces of shredded sharp cheddar cheese, mixing until it has melted and the sauce is uniformly cheesy. Keep the sauce warm over low heat while you assemble the rest of the dish.
6. Stir the 1 tablespoon of chicken base (or the equivalent of 3 dissolved bouillon cubes) and the ½ teaspoon of garlic powder into the cheese-tomato sauce. Taste and adjust the seasoning slightly if desired—remember that the shredded cheddar and chicken base already contribute saltiness.
7. Add the 5 cups of chopped cooked chicken to the sauce, folding gently so the chicken is evenly coated with the cheesy Rotel mixture. Heat the mixture until the chicken is warmed through.
8. Combine the cooked and drained spaghetti with the chicken and sauce. Toss carefully with tongs or two forks so every strand of spaghetti is covered with sauce and the chicken is distributed evenly.
9. Stir in most of the chopped scallions, reserving a handful for garnish. Folding them in adds fresh color and a mild onion flavor throughout the dish.
10. If you’d like a crunchy topping, sprinkle the ¾ cup of crushed Ritz crackers over the surface of the pasta. For a warm, golden finish, transfer the assembled spaghetti to an oven-safe baking dish, sprinkle the crackers evenly, and place under a hot broiler for 1–2 minutes—watch closely so the crackers don’t burn. Alternatively, you can simply sprinkle the crackers on top just before serving for instant crunch.
11. Serve the Cheesy Chicken Spaghetti with Rotel immediately, garnished with the reserved scallions for a bright, fresh finish.

Serving suggestions and variations

• For a little extra green, toss in a couple of handfuls of fresh baby spinach at the end and let it wilt in the hot sauce before serving.
• To make this more pepper-forward, add a diced jalapeño (seeded if you prefer less heat) to the sauce while the Rotel warms.
• If you like a smoky note, stir in a teaspoon of smoked paprika or swap half the cheddar for smoked cheddar.
• For a lighter version, reduce the cream cheese by 2 ounces and add a splash of low-fat milk to loosen the sauce while still keeping a creamy texture.

Make-ahead and storage

This dish stores well. Cool completely, then refrigerate the leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop over low heat, adding a tablespoon or two of water or milk if the sauce has thickened. If frozen, place in a freezer-safe container for up to 2 months; thaw overnight in the refrigerator before reheating.

Tips for success

• Soften the cream cheese ahead of time—cut it into cubes and let it sit at room temperature for 20–30 minutes so it blends smoothly.
• Be careful when melting the cheese; low and slow heat prevents the sauce from becoming grainy.
• Measure the chicken after chopping so you hit the 5-cup target—this keeps the chicken-to-pasta ratio balanced.
• If your chicken has darker meat or a stronger flavor, taste the sauce before adding extra salt; the chicken base and cheddar already add seasoning.

Why this comforting pasta works

Combining spaghetti with a tomato-and-cheese sauce that includes Rotel and cream cheese produces a rich, slightly tangy base that clings to the strands of pasta. Shredded cooked chicken adds substance without a lot of extra time, and scallions finish the dish with a crisp, oniony lift. The crunchy Ritz topping is optional, but it brings a delicious contrast to the creamy texture below. Altogether, this Cheesy Chicken Spaghetti with Rotel is straightforward to make and reliably pleasing to a crowd.
