Ingredients
  

Ingredients
  • 1 lb spaghetti noodles
  • 2 cups cooked chicken, shredded or diced
  • 2 cups Monterey Jack cheese, shredded
  • 1 cup cheddar cheese, shredded
  • 1/2 cup BBQ sauce (your favorite brand)
  • 1/4 cup sour cream
  • 1/4 cup cream cheese, softened
  • 1 small onion, finely diced
  • 2 cloves garlic, minced
  • 1 cup chicken broth
  • 1/2 cup milk
  • 1 tsp smoked paprika
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • Salt and pepper to taste
  • Fresh parsley for garnish (optional)

Method
 

Instructions
  1. Preheat your oven to 375°F (190°C) and grease a 9x13 inch baking dish.
  2. Cook the spaghetti according to package directions until al dente. Drain and set aside.
  3. In a large skillet, sauté the diced onion until translucent, about 3-4 minutes. Add minced garlic and cook for another minute until fragrant.
  4. Add the cooked chicken, BBQ sauce, chicken broth, smoked paprika, garlic powder, and onion powder to the skillet. Stir to combine and simmer for 5 minutes.
  5. Reduce heat to low and stir in sour cream and cream cheese until smooth and creamy.
  6. Combine the sauce with the cooked spaghetti, mixing thoroughly to coat every strand.
  7. Transfer the mixture to the prepared baking dish and top with both Monterey Jack and cheddar cheeses.
  8. Bake for 20-25 minutes until the cheese is melted and bubbly, and the edges are golden brown.
  9. Let rest for 5 minutes before serving. Garnish with fresh parsley if desired.

Notes

For best results, use freshly shredded cheese instead of pre-shredded varieties. Rotisserie chicken works perfectly for time savings. For a crispy top, broil for last 2-3 minutes. Assemble ahead and refrigerate for up to 24 hours before baking.
