Tips for the Best Dairy-Free French Onion Chicken

• Caramelize the onions slowly – This enhances their natural sweetness.
• Deglaze the pan – Scrape up the browned bits for extra depth of flavor.
• Use high-quality broth – A good beef or chicken broth makes a difference.
• Let the sauce reduce – This concentrates the flavors for a richer taste.
• Don’t overcook the chicken – Use a meat thermometer to check for 165°F (75°C).
