Step-by-Step Instructions
Step 1: Preheat your oven to 375°F (190°C). Bring a large pot of salted water to boil and cook spaghetti according to package directions until al dente. Drain and set aside.
Step 2: While pasta cooks, heat olive oil in a large skillet over medium heat. Add chopped onions and bell peppers, sautéing until softened, about 5-7 minutes.
Step 3: Add cooked chicken to the skillet along with garlic powder, smoked paprika, salt, and pepper. Stir to combine and cook for 2-3 minutes until heated through.
Step 4: In a large mixing bowl, combine the cooked spaghetti, chicken and vegetable mixture, BBQ sauce, and sour cream. Stir until everything is evenly coated.
Step 5: Transfer the mixture to a greased 9×13 inch baking dish. Spread evenly and top with shredded Monterey Jack cheese.
Step 6: Bake for 20-25 minutes, or until the cheese is melted and bubbly with golden edges. For extra browning, broil for the last 2-3 minutes.
Step 7: Remove from oven and let rest for 5 minutes before serving. Garnish with fresh parsley if desired.
