Description
Enjoy the rich, comforting flavors of French Onion Chicken Orzo Casserole—a creamy, cheesy, and hearty one-pan meal made with caramelized onions, juicy chicken, and tender orzo.
Ingredients
- 1 lb boneless, skinless chicken breasts or thighs, cut into chunks
- 2 large yellow onions, thinly sliced
- 2 tbsp butter
- 1 tbsp olive oil
- 3 cloves garlic, minced
- 1 cup uncooked orzo pasta
- 2 cups beef or chicken broth
- ½ cup heavy cream or half-and-half
- 1 cup shredded Gruyère cheese
- ½ cup shredded mozzarella or Swiss cheese
- 1 tsp fresh thyme (or ½ tsp dried)
- 1 bay leaf (optional)
- ½ tsp salt
- ¼ tsp black pepper
- Optional: splash of white wine for deglazing
- Fresh parsley for garnish
Instructions
- Caramelize the Onions – Heat butter and olive oil in a large skillet over medium-low heat. Add sliced onions and cook for 25–30 minutes, stirring occasionally, until golden brown and caramelized. Add garlic and thyme during the last few minutes.
- Cook the Chicken – Season chicken with salt and pepper. Add to the pan and cook until lightly browned. Remove from skillet and set aside.
- Toast the Orzo – In the same skillet, stir in the orzo pasta and toast for 1–2 minutes to absorb the onion flavor.
- Add Liquid – Pour in broth and heavy cream, stirring to combine. Add bay leaf if using. Bring to a gentle simmer.
- Assemble the Casserole – Transfer the orzo mixture into a greased baking dish. Nestle the chicken pieces on top, then sprinkle with Gruyère and mozzarella cheese.
- Bake – Cover with foil and bake at 375°F (190°C) for 20 minutes. Remove foil and bake for another 10 minutes, until the cheese is melted and golden brown.
- Serve – Let rest for 5 minutes, then garnish with fresh parsley before serving.
Notes
- Take your time with the onions: Slow caramelization creates the deep, sweet flavor that defines this dish.
- Use quality cheese: Gruyère adds authentic French flavor, but Swiss or mozzarella also work beautifully.
- Want extra flavor? Deglaze the onions with a splash of white wine or sherry.
- For a lighter version: Use light cream or evaporated milk instead of heavy cream.
- Make ahead: Assemble the casserole and refrigerate up to 24 hours before baking.
