French Onion Chicken Orzo Casserole
Ingredients
Method
1. Build That Deep Onion Flavor
Warm butter and olive oil in a large oven-safe pan over medium-low heat. Toss in the sliced onions, sugar, and salt. Cook low and slow, stirring often, until the onions turn soft, golden, and richly caramelized—this takes about 30–40 minutes. Add the garlic and cook briefly until fragrant.
2. Prep the Chicken
Season your chicken lightly with salt and pepper. Sear it in another pan until the outside turns golden.No need to cook it through—it’ll finish later in the oven.Set aside.
3. Bring Everything Together
Pour chicken broth into the onion mixture and scrape up those flavorful browned bits (that’s gold, IMO).Stir in the orzo, cream, thyme, and partially cooked chicken. Let it gently simmer for about 5–7 minutes.The orzo should soften slightly but still have a bite.
4. Add Cheese & Bake
Mix in half of the mozzarella and Parmesan. Sprinkle the rest on top.Transfer the pan to a preheated oven at 375°F (190°C) and bake uncovered for 20–25 minutes.You’re looking for a bubbly, golden top—basically irresistible.
5. Rest & Serve
Let the casserole sit for 5–10 minutes before serving.This helps everything thicken up nicely. Garnish with thyme or parsley if you like.
