Making a delicious and elegant dinner that doesn't take long to prepare is possible on a busy weeknight. This gluten-free chicken dish is filling, packed with flavor, and takes less than 30 minutes to bake. Mayonnaise may seem like an odd ingredient to combine with chicken (this recipe is actually adapted from a recipe on a hellmann's jar) a thin layer over top a boneless, skinless chicken breast helps lock in moisture and flavor. When combined with dried minced onion, the mayonnaise layer forms a scrumptious crust over the chicken. We used hellmann's mayonnaise with olive oil because it contains fewer calories and less fat than regular mayonnaise, but you can use whichever brand of mayonnaise you prefer (ensuring it is gluten-free of course, always read labels)once the chicken is nearly done baking, low moisture part skim, shredded mozzarella is added to create a second layer of deliciousness. To finish off the chicken with traditional caprese style flavors, sliced tomatoes are arranged over top followed by freshly chopped basil. Really want to kick the flavor up a notch? Finish off the dish with a drizzle of balsamic reduction, which is super easy to make from scratch.
