Rotel Chicken Spaghetti is the ultimate comfort food that brings together tender pasta, seasoned chicken, and that iconic creamy tomato sauce with a delightful kick. This beloved Tex-Mex inspired dish has been a family favorite for generations, and once you make it, you’ll understand why it’s such a crowd-pleaser.
What makes this recipe truly special is the combination of Rotel tomatoes—those perfectly spiced diced tomatoes with green chilies—mixed with cream cheese and cheddar cheese to create a sauce that’s both comforting and exciting. The beauty of this dish lies in its simplicity and versatility. Whether you’re feeding a family of four or preparing a casserole for a potluck, this recipe scales beautifully and can be made ahead of time, making it perfect for busy weeknights or entertaining guests.
I’ve been making this recipe for years, and I’ve perfected it through countless iterations. The secret is using quality chicken, not overcooking the pasta, and getting the sauce to that perfect creamy consistency. Some people add a touch of Velveeta for extra creaminess, while others prefer the sophistication of sharp cheddar. Some families swear by adding jalapeños or a dash of hot sauce for extra heat.
This dish is incredibly forgiving and encourages creativity. You can add bell peppers, onions, or mushrooms for extra vegetables, or keep it simple and classic. Many home cooks enjoy topping it with crispy bacon bits or fresh cilantro for garnish. The casserole can be assembled the night before and baked when you’re ready, making it an excellent choice for meal planning.

Ingredients
- 1 pound spaghetti pasta
- 2 pounds boneless, skinless chicken breasts
- 2 cans (10 oz each) Rotel tomatoes with green chilies, undrained
- 8 ounces cream cheese, softened
- 2 cups shredded sharp cheddar cheese, divided
- 1 can (10.5 oz) cream of mushroom soup
- 1 cup chicken broth
- 1/2 cup milk
- 1 medium onion, diced
- 3 cloves garlic, minced
- 2 tablespoons butter
- 1 teaspoon chili powder
- 1/2 teaspoon cumin
- Salt and black pepper to taste
- 1/2 cup panko breadcrumbs
- 2 tablespoons melted butter for topping
- 1/4 cup fresh cilantro, chopped (optional)
- Crispy bacon bits for garnish (optional)
Instructions
- Preheat your oven to 350°F and lightly grease a 9×13 inch baking dish with butter or cooking spray. This ensures your casserole won’t stick and will bake evenly.
- Season the chicken breasts generously on both sides with salt, pepper, and half of the chili powder. Heat 2 tablespoons of butter in a large skillet over medium-high heat until it foams and becomes fragrant.
- Once the butter is hot, carefully place the chicken breasts into the skillet. Sear for 5-6 minutes on each side until golden brown on the outside. The chicken doesn’t need to be fully cooked through at this point. Remove the chicken to a cutting board and set aside.
- In the same skillet, reduce heat to medium and add the diced onion. Sauté for 3-4 minutes, stirring occasionally, until the onion becomes translucent and fragrant. Add the minced garlic and cook for another 30 seconds.
- Add the cream of mushroom soup to the skillet and stir to combine with the onion and garlic mixture. Pour in the chicken broth and milk, stirring constantly until smooth and well combined.
- Cut the softened cream cheese into small cubes and add to the skillet, stirring constantly over medium heat until the cream cheese melts completely and creates a smooth sauce. This should take about 2-3 minutes.
- Stir in both cans of Rotel tomatoes with their juice, along with the remaining chili powder and cumin. Mix everything together thoroughly. Taste and adjust seasonings as needed with salt and pepper.
- Bring a large pot of salted water to a rolling boil. Add the spaghetti and cook according to package directions until al dente, usually about 8-10 minutes. Drain the pasta in a colander but do not rinse it.
- Cut the cooked chicken breasts into bite-sized pieces or shred them with two forks, depending on your preference. Shredded chicken mixes more evenly throughout the dish.
- Add the cooked pasta to the sauce in the skillet and stir gently but thoroughly to coat every strand with the creamy Rotel mixture. Add the cooked chicken pieces and fold in gently.
- Stir in 1.5 cups of the shredded cheddar cheese, reserving the remaining 1/2 cup for topping. Mix until the cheese melts and everything is well combined and creamy.
- Transfer the entire mixture to your prepared baking dish, spreading it out in an even layer. Make sure the pasta and chicken are distributed evenly throughout.
- In a small bowl, mix together the panko breadcrumbs with 2 tablespoons of melted butter until the breadcrumbs are evenly coated. Sprinkle this mixture over the top of the casserole.
- Top the breadcrumb mixture with the reserved 1/2 cup of shredded cheddar cheese for a golden, cheesy top layer.
- Bake uncovered in the preheated 350°F oven for 25-35 minutes, until the casserole is hot and bubbly throughout and the top is golden brown and slightly crispy.
- Remove from the oven and let rest for 5 minutes before serving. This allows the casserole to set slightly and makes serving easier.
- Garnish with fresh cilantro and crispy bacon bits if desired. Serve hot and enjoy!
Pro Tips
Chicken Options: Use rotisserie chicken from the grocery store to save time on cooking. You’ll need about 4 cups of shredded meat. Alternatively, poach chicken breasts in simmering chicken broth for about 15 minutes for tender, flavorful results.
Cheese Variations: While sharp cheddar is traditional, you can experiment with Monterey Jack, pepper jack for heat, or a combination of cheeses. Some people add Velveeta for extra creaminess and smooth sauce consistency.
Adding Vegetables: Diced bell peppers, sliced mushrooms, or fresh spinach can be added to the sauce for extra nutrition and flavor. Sauté them with the onions in step 4.
Spice Level: If you prefer less heat, use one can of regular diced tomatoes instead of two cans of Rotel. For more spice, add sliced jalapeños or a dash of cayenne pepper to the sauce.
Leftovers and Storage: This casserole stores beautifully in the refrigerator for up to 4 days in an airtight container. Reheat in a 350°F oven for about 15-20 minutes until heated through, or microwave individual portions.
Freeze Instructions: This dish freezes exceptionally well for up to 3 months. Cool completely, wrap tightly in plastic wrap and then aluminum foil, and label with the date. Thaw overnight in the refrigerator before baking, adding extra time if baking from frozen.
Pasta Tips: Don’t overcook the pasta since it will continue cooking in the oven. Al dente pasta holds its texture better in casseroles. Use regular spaghetti or try penne for a different texture.
Sauce Consistency: If your sauce seems too thick, add a splash of chicken broth or milk. If too thin, simmer a few extra minutes. The consistency should be creamy but not soupy.
Serving Suggestions: Pair with garlic bread, a crisp green salad, or steamed broccoli. A glass of crisp white wine like Sauvignon Blanc complements the spiced tomato sauce beautifully.
Scaling Recipe: This recipe easily doubles for larger crowds. Use a 9×13 baking dish for the single recipe, or two dishes for a doubled batch. Increase baking time slightly if using a larger dish.
