Ingredients
- 2 pounds boneless skinless chicken breasts
- 1 (16-ounce) package spaghetti
- 1 (10-ounce) can Ro*Tel tomatoes
- 2 (10.5-ounce) cans cream of mushroom soup
- 1 (16-ounce) package Velveeta cheese
- 4 ounces cream cheese
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 cup shredded sharp cheddar cheese
Instructions
- Begin by placing your boneless, skinless chicken breasts into a spacious pot, then generously cover them with water.
- Gently simmer the chicken over medium-low heat until it’s thoroughly cooked, ensuring it’s tender and ready for shredding.
- Carefully remove the cooked chicken from the pot and set it aside to cool just enough to handle comfortably.
- Once cooled, effortlessly shred the chicken into bite-sized pieces using two forks – it should pull apart beautifully.
- While the chicken cools, preheat your oven to a cozy 350°F (175°C).
- Prepare a 13×9-inch baking dish by lightly coating it with nonstick cooking spray, ensuring an easy cleanup later.
- Now, cook your spaghetti according to the package instructions, aiming for that perfect al dente bite.
- Once cooked, drain the spaghetti thoroughly and set it aside, ready to join our creamy sauce.
- In a separate large pot, combine the undrained Ro*Tel tomatoes, both cans of cream of mushroom soup, the Velveeta cheese, and the cream cheese.
- Warm this mixture over low heat, stirring continuously until all the cheeses have melted into a wonderfully smooth and cohesive sauce.
- Now, stir in the aromatic garlic powder and onion powder, infusing the sauce with irresistible flavor.
- Gently fold in your shredded chicken and the cooked spaghetti into the luscious cheese mixture.
- Ensure everything is thoroughly mixed, so every strand of spaghetti and every piece of chicken is beautifully coated in the rich sauce.
- Transfer this glorious mixture into your prepared baking dish, spreading it evenly.
- Generously sprinkle the shredded sharp cheddar cheese over the entire surface of the casserole.
- Bake for 20 to 30 minutes, or until the casserole is gloriously hot and bubbly and the top cheese is perfectly melted and slightly golden.
- Serve this ultimate comfort food warm, and prepare for rave reviews!
