🍅 Ingredients You’ll Need
For the Casserole:
- 12 oz spaghetti, uncooked
- 2 cups cooked chicken, shredded (rotisserie or boiled works well)
- 1 can (10 oz) Rotel diced tomatoes with green chilies, undrained
- 1 can (10.5 oz) cream of chicken soup
- 8 oz cream cheese, softened
- 1 cup shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- Salt and pepper, to taste
- 1 tablespoon olive oil or butter for greasing
Optional Toppings:
- Additional shredded cheese for topping
- Crushed tortilla chips or breadcrumbs for crunch
- Fresh cilantro or parsley for garnish
🍝 Step-by-Step Instructions
Step 1: Cook the Spaghetti
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch casserole dish.
Cook the spaghetti according to package instructions until al dente, then drain and set aside. Make sure not to overcook—the pasta will continue to bake in the oven with the sauce.
Step 2: Prepare the Creamy Chicken Mixture
In a large mixing bowl, combine the cream of chicken soup, cream cheese, and Rotel. Stir until smooth and creamy. The Rotel adds a zesty, slightly spicy flavor that elevates the casserole from ordinary to extraordinary.
Next, stir in shredded chicken, cheddar, and mozzarella cheese. Season with garlic powder, onion powder, salt, and pepper. Mix until everything is evenly coated in the creamy, cheesy sauce.
Step 3: Combine with Spaghetti
Fold the cooked spaghetti into the creamy chicken mixture, ensuring each noodle is coated thoroughly. This ensures every bite has a perfect balance of chicken, sauce, and pasta.
Transfer the mixture into the prepared casserole dish, spreading it evenly.
Step 4: Add Toppings
Sprinkle additional shredded cheese over the top for a melty, golden layer. If you like a bit of crunch, add crushed tortilla chips or breadcrumbs. The topping creates a delightful texture contrast with the creamy interior.
Step 5: Bake the Casserole
Bake uncovered in the preheated oven for 25–30 minutes, or until the cheese is melted and bubbly. The edges should be slightly golden, and the center hot and creamy. For extra golden cheese on top, broil for 1–2 minutes at the end—but watch carefully to prevent burning.
Step 6: Cool and Serve
Let the casserole cool for 5–10 minutes before serving. This allows the sauce to thicken slightly, making it easier to portion. Garnish with fresh parsley or cilantro for a pop of color and freshness.
