Variations and tips
This recipe adapts wonderfully to different tastes and dietary needs. For a lighter version, you can use low-fat cheeses and increase the proportion of marinara sauce to create a more flavorful dish without added calories. For those who like a little heat, adding red pepper flakes or diced jalapeños to the sauce can add a spicy touch. To make this dish gluten-free, make sure your marinara sauce and chicken broth are certified gluten-free. You can also vary the herbs by using a blend of parsley, oregano, or thyme for different flavor profiles.
