• 1 large onion , chopped
• 4 cloves garlic , minced, divided
• 6 medium Roma tomatoes , diced
• 2 tablespoons butter
• 1 tablespoon all-purpose flour , or more as needed

Instructions

1. 1 Preheat the oven to 400 degrees F (200 degrees C).
2. 2 Bring a large pot of lightly salted water to a boil. Cook ziti in boiling water, stirring occasionally, until tender yet firm to the bite, about 10 minutes. Drain.
3. 3 While ziti is cooking, heat olive oil in a large skillet over medium to medium-high heat. Add chicken, Cajun seasoning, and salt. Sauté until chicken is cooked through and beginning to caramelize, about 10 minutes. Add bell peppers, onion, and 1/2 of the garlic; cook until tender, 5 to 7 minutes. Add tomatoes and bring to a simmer.
4. 4 Meanwhile, melt butter in a medium saucepan over medium heat. Add remaining garlic and sauté until fragrant, about 1 minute. Add flour; cook and stir for 1 minute. Slowly whisk in milk and bring to a gentle boil. Stir in Parmesan cheese, salt, and pepper. Add more Parmesan to thicken or more milk to thin to your liking.
5. 5 Add cooked ziti to chicken mixture; toss to coat. Transfer to a deep casserole dish. Pour cheese sauce over pasta mixture and top with mozzarella cheese.
6. 6 Bake in the preheated oven until the top is golden and bubbly, about 15 minutes.
