Ingredients

• 1 lb spaghetti noodles
• 2 cups cooked chicken breast, shredded or diced
• 2 cups Monterey Jack cheese, shredded
• 1 cup sharp cheddar cheese, shredded
• 1/2 cup barbecue sauce
• 1/2 cup sour cream
• 1/4 cup cream cheese, softened
• 1 small onion, finely diced
• 1 bell pepper, diced
• 2 cloves garlic, minced
• 1 can (10.5 oz) cream of chicken soup
• 1/2 cup chicken broth
• 1 tsp smoked paprika
• 1/2 tsp black pepper
• 1/4 tsp salt
• Fresh parsley for garnish

Step-by-Step Instructions

Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish.

Cook the spaghetti according to package directions until al dente. Drain well and set aside.

In a large skillet, sauté the diced onion and bell pepper until softened, about 5 minutes. Add minced garlic and cook for another minute until fragrant.

In a large mixing bowl, combine the cooked spaghetti, sautéed vegetables, shredded chicken, barbecue sauce, sour cream, cream cheese, cream of chicken soup, chicken broth, smoked paprika, black pepper, and salt. Mix until everything is well combined.

Transfer the mixture to the prepared baking dish and spread it evenly. Top with the shredded Monterey Jack and cheddar cheeses.

Bake for 25-30 minutes, or until the cheese is melted and bubbly and the edges are golden brown.

Let the casserole rest for 5-10 minutes before serving. Garnish with fresh parsley.
