A comforting and easy-to-make casserole combining caramelized onions, tender chicken, orzo pasta, and a creamy cheese sauce, perfect for cozy weeknight dinners or family gatherings.
Caramelize onions low and slow for best flavor. Use quality French onion soup mix for signature taste. For dairy-free, substitute cream cheese and sour cream with plant-based alternatives. Cover casserole with foil if top browns too fast during baking. Leftovers store well refrigerated up to 3 days or frozen up to 2 months.
