This comforting casserole recipe features tender chicken, mixed vegetables, and a creamy sauce, all baked to perfection. The chicken is cooked with onions and garlic, then combined with a medley of vegetables like corn, peas, and carrots. The creamy sauce is made with a combination of chicken broth, milk, and flour, creating a luscious coating for the casserole. Top it with breadcrumbs and grated cheese before baking for a golden and cheesy crust.
