Ingredients

Main Ingredients

  • 1 lb Boneless chicken thighs or breasts Rotisserie chicken can be used near the end.
  • 2 large Yellow onions, sliced Sweet onions can also be used.
  • 1 cup Orzo Small pasta like ditalini can be used but may require more liquid.
  • 4 cups Beef or chicken broth Use beef broth for true French onion flavor; chicken is fine with extra thyme.
  • 1 cup Heavy cream or half and half For dairy-free, use unsweetened oat cream or a creamy plant milk.
  • 1 cup Shredded Gruyere cheese Swiss cheese is a budget-friendly swap.
  • 1 tsp Dijon mustard Optional for added savory flavor.
  • 1 clove Garlic, minced Add for flavor.
  • 1 tsp Fresh or dried thyme Italian seasoning can substitute.
  • 1 tsp Sugar A pinch to help with caramelizing onions if they are not sweet enough.
  • 2 tbsp Butter or oil For browning the chicken.

Instructions

Preparation

  • Season the chicken with salt and pepper. Sear in butter or oil until golden but not fully cooked.

  • Stir in minced garlic, thyme, and sugar.
  • Pour in broth and cream, and stir in Dijon mustard if using.
  • Add orzo, bring to a gentle simmer, cover, and cook until tender, stirring occasionally.
  • Stir in shredded cheese and top with more cheese. Bake for a few minutes until bubbly if desired.
  • Let it sit for 5 minutes before serving to thicken.
