- Try adding a pinch of cayenne pepper for a mild spicy kick.
Storage

FAQs
Can I use rotisserie chicken instead of cooking my own?
Yes, using rotisserie chicken is a convenient shortcut. Just shred it and add it directly to the mixture.

Ro*Tel adds a nice mild heat and flavor, but you can substitute with diced tomatoes and green chilies or plain diced tomatoes if you prefer less spice.

Ingredients
Chicken
- 2 pounds boneless skinless chicken breasts
Pasta
- 1 (16-ounce) package spaghetti
Cheese and Sauces
- 1 (10-ounce) can Ro*Tel Tomatoes (undrained)
- 2 (10.5-ounce) cans cream of mushroom soup (undiluted)
- 1 (16-ounce) package Velveeta cheese
- 4 ounces cream cheese
- 1 cup shredded sharp cheddar cheese
Spices
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
Instructions
- Cook the chicken: Place the chicken breasts in a large pot and cover just with water. Cook over medium-low heat until the chicken is fully cooked but not boiling to avoid toughness. Once done, let cool slightly, then shred the chicken using two forks.
- Prepare the baking dish: Preheat your oven to 350°F (175°C). Lightly grease a 13×9-inch baking dish with nonstick cooking spray to prevent sticking.
- Cook the spaghetti: Boil the spaghetti according to package instructions until al dente. Drain well and set aside.
- Make the cheese sauce and combine: In a large pot over low heat, combine the undrained Ro*Tel tomatoes, undiluted cream of mushroom soup, Velveeta cheese, and cream cheese. Stir constantly until all the cheeses have melted into a smooth sauce. Add garlic powder and onion powder for flavor. Then add the shredded chicken and cooked spaghetti. Stir everything together thoroughly.
- Bake the casserole: Pour the combined mixture into the prepared baking dish. Evenly sprinkle the shredded sharp cheddar cheese on top. Bake in the preheated oven for 20 to 30 minutes, until the casserole is hot throughout and the cheese on top has melted and slightly browned.
Notes
- To prevent drying out the chicken, avoid boiling vigorously; simmer gently instead.
- If Velveeta cheese is unavailable, a combination of processed cheese and mild cheddar can be used as a substitute.
- You can add diced bell peppers or jalapeños with the Ro*Tel tomatoes for extra flavor and a bit of heat.
- Leftovers can be stored in the refrigerator for 3-4 days and reheated in the oven or microwave.
- For a lower-fat version, use low-fat cream cheese and reduced-fat cheddar cheese.
