This dish is perfect for batch cooking. It’s easy to prep ahead, freeze in portions, or reheat for quick lunches or dinners. Just bake it once and enjoy the convenience all week long.
Why This Recipe Belongs in Your Diet
This pasta bake keeps fat in check by using fat-free Greek yogurt to create a creamy texture, replacing heavy cream or ricotta. Chicken breast delivers lean protein to keep you full, while the tomato-based sauce brings bold flavor without relying on oil or butter. The result is a balanced, low-fat meal that’s both satisfying and smart.
