Ingredients for Rotel Chicken Spaghetti

To create the perfect cheesy casserole, you’ll need the following ingredients:
Essential Ingredients
- 1 pound spaghetti
- 1 tablespoon extra virgin olive oil
- 1/2 cup diced onion
- 1/2 cup diced bell pepper
- 10 ounce can Rotel tomatoes with green chilies (do not drain, the juices add flavor)
- 2 cups cooked and shredded chicken breast (rotisserie chicken works great as a shortcut)
- 1/2 teaspoon kosher salt
- 1/2 teaspoon chili powder
- 1/4 teaspoon black pepper
- 2 cups cubed Velveeta cheese for a smooth, meltable sauce
- 10.5 ounce can cream of chicken soup
- 3/4 cup chicken broth
- 1 cup shredded cheddar cheese for topping
Optional Ingredients
- 1/2 teaspoon cumin for a warm, earthy note
- 2 teaspoons fresh chopped parsley for garnish (cilantro is a great substitute)
How to Prepare the Chicken Sauce
Here’s how to build the creamy sauce:
- Sauté the Vegetables: Heat the olive oil in a large skillet over medium heat, then add the diced onion and bell pepper. Cook for 4-5 minutes until softened.
- Add the Chicken and Seasonings: Stir in the shredded chicken, kosher salt, chili powder, black pepper, cumin if using, and the undrained Rotel. Simmer for 3 minutes so the flavors can meld.
- Melt the Cheese: Reduce the heat to low, then stir in the cream of chicken soup, chicken broth, and cubed Velveeta. Stir for 5-6 minutes until the cheese is fully melted and the sauce is smooth.
Cooking the Spaghetti
While the sauce simmers, you can cook the pasta:
- Stovetop Method: Bring a large pot of salted water to a rolling boil, add the spaghetti, and cook for 9-10 minutes until al dente. Drain well without rinsing so the sauce clings to every strand.
- Make-Ahead Method: Cook the spaghetti 2 minutes less than the package directs, toss it with a teaspoon of olive oil, and refrigerate for up to 24 hours. Warm it in the skillet for 2 minutes before mixing it with the sauce.

Assembly: Bringing It All Together
Once your sauce and pasta are ready, it’s time to assemble your casserole!
- Combine the Pasta and Sauce: Add the drained spaghetti to the skillet and toss for about 2 minutes until every strand is coated.
- Transfer and Top: Spread the mixture into a greased 9×13-inch baking dish and sprinkle the shredded cheddar evenly over the top.
- Bake Until Bubbly: Bake at 375°F for 10-12 minutes until the cheese is melted and golden around the edges.
- Garnish and Serve: Sprinkle with chopped parsley or cilantro and serve warm.
Variations and Customizations
One of the great things about Rotel Chicken Spaghetti is its versatility!
- Spicier Kick: Use Rotel Hot or add a pinch of cayenne pepper to the sauce.
- Veggie Boost: Stir in a cup of frozen corn or chopped baby spinach during the sauce step.
- Protein Swap: Use cooked ground turkey or shredded pork in place of the chicken.
- Crunchy Topping: Sprinkle crushed tortilla chips over the cheddar before baking for added texture.
Serving Suggestions
A crisp green salad or a warm pan of golden cornbread makes this casserole feel like a complete Southern-style dinner.
Serve it with sweet iced tea or a cold lemonade for a refreshing contrast to the rich, cheesy sauce.

Recipe FAQ’s
Can I use rotisserie chicken instead of cooked chicken breast?
Yes, a store-bought rotisserie chicken works perfectly and saves time. Shred about 2 cups of meat from a standard rotisserie chicken.
Can I use cilantro instead of parsley?
Absolutely, cilantro adds a bright, fresh flavor that pairs nicely with the Rotel. Add it just before serving so it stays vibrant.
How should I store leftovers?
Refrigerate leftovers in an airtight container for up to 4 days. Reheat with a splash of chicken broth in the microwave to loosen the sauce.
