My favorite moment is always lifting the broiler lid and seeing that perfectly bubbly cheese. My little sister used to sneak in and beg for extra cheese on hers when I made this for family suppers.
Storage Tips
Refrigerate leftovers in a tightly lidded container and they keep for up to three days
To reheat place gently in a skillet with a splash of broth and cook over low heat until warmed through to keep the chicken moist
Freezing is not ideal as the cheese can separate and onions may lose their texture
Ingredient Substitutions
If you cannot find Gruyère try Swiss or Emmental for a similar melt
Red onions can be used for a sweeter twist though yellow gives the most classic flavor
Chicken thighs work for an even juicier meal but increase cooking time slightly to ensure they are tender
Serving Suggestions
Pair with buttery green beans or a simple salad to keep things light and fresh
For a heartier option serve with mashed cauliflower or creamy polenta to soak up the sauce
If you want more classic French onion flair sprinkle with fresh chives or a few gluten free croutons
