Chicken
- 2 boneless chicken breasts or thighs
Pasta
- 8 ounces spaghetti noodles, cooked al dente
Dairy & Sauce
- 1 cup shredded Monterey Jack cheese (plus extra for topping)
- 1 cup sour cream
- 1 can (10.5 oz) condensed cream of mushroom or chicken soup
- 2 tablespoons butter
- 1/4 cup milk
Seasonings & Extras
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- Salt and pepper, to taste
- 1/4 cup chopped green chilies or jalapeños (optional)
- Cook the Spaghetti: Boil spaghetti noodles in salted water for about 8 minutes until just al dente. Drain and set aside to cool slightly before mixing into the sauce.
- Prepare the Chicken: In a skillet over medium heat, cook chicken breasts or thighs for 6-8 minutes per side until no longer pink inside. Let cool, then shred into bite-sized pieces using two forks.
- Make the Cheese Sauce: In a large mixing bowl, combine sour cream, condensed cream of mushroom or chicken soup, shredded Monterey Jack cheese, garlic powder, onion powder, salt, and pepper. Stir thoroughly until smooth and creamy.
- Combine Ingredients: Add the cooked spaghetti and shredded chicken to the cheese sauce mixture. If using, fold in the chopped green chilies or jalapeños for added flavor and a mild spicy kick.
- Assemble and Bake: Transfer the combined mixture into a greased baking dish. Sprinkle extra shredded Monterey Jack cheese evenly on top. Bake in a preheated oven at 350°F (175°C) for 20-25 minutes until the cheese on top is melted and slightly browned.
Notes
- Use freshly shredded Monterey Jack cheese for better melt and texture.
- Avoid overcooking the pasta to prevent mushiness after baking.
- Allow the casserole to rest for 5 minutes after baking to set properly.
- Adjust the amount of green chilies or jalapeños to customize the spice level.
- Consider mixing Monterey Jack with cheddar or mozzarella cheese to enhance flavor and meltiness.
