1. Preheat your oven to 375°F (190°C). Grease a large baking dish with a little olive oil or nonstick spray.
2. Cook the pasta according to package instructions until al dente. Drain and set aside.
3. While the pasta cooks, heat olive oil in a skillet over medium heat. Add minced garlic, chopped red onion, and diced bell peppers. Sauté for about 4-5 minutes until softened and fragrant.
4. In a large bowl, combine the cooked pasta, sautéed veggies, shredded chicken, barbecue sauce, sour cream, half of the cheddar cheese, and half of the mozzarella cheese. Season with salt and pepper to taste. Mix everything gently until well combined.
5. Transfer the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining cheddar and mozzarella cheese over the top.
6. Bake uncovered for 20-25 minutes, or until the cheese is melted and bubbly, and the edges are slightly golden.
7. Remove from the oven and let it cool for 5 minutes. Garnish with fresh parsley or cilantro before serving.

One of my favorite moments while baking this is that golden cheese crust that forms on the top—that’s when you know you’re in for a treat. Mama Lou always said, “Wait for the crust, Sofia; that’s the best part.” It’s these little pieces of advice that turn simple cooking into cherished rituals.
