Texture & Flavor Secrets

The richness of the dish comes from the balance of caramelized onions with juicy, tender chicken and that blanket of melty, browned cheese. The onions give a slightly sweet base, the broth brings umami depth, and the cheese adds a savory, creamy finish. The contrast of saucy onions with seared chicken makes every bite satisfying.
