How to Make French Onion Chicken Orzo Casserole

Step 1: Caramelize the Onions

In a large oven-safe skillet or Dutch oven, melt butter and olive oil over medium-low heat. Add thinly sliced onions and cook slowly, stirring often, for about 30–40 minutes, until golden and jammy. Just when they reach perfection, stir in garlic for one more fragrant minute.

Pro Tip: Patience is key! Slow caramelization makes all the difference—rush it and you’ll miss that deep, sweet flavor.

Step 2: Brown the Chicken

While the onions cook, season your chicken with salt and pepper. In a separate skillet (or after removing onions temporarily), brown the chicken just until golden on both sides. Don’t worry about cooking it through—it’ll finish in the oven.

Step 3: Deglaze and Combine

Pour in beef broth to the onions, scraping up all the flavorful bits stuck to the bottom. Stir in the orzo, heavy cream, thyme, and the browned chicken. Simmer for 5–7 minutes, until the orzo starts soaking up the liquid but still has a little bite.

Step 4: Add Cheese and Bake

Stir in half of the Gruyère cheese until melted. Sprinkle the rest on top, then transfer your skillet to a 375°F (190°C) oven. Bake uncovered for 20–25 minutes, or until golden and bubbly.

Step 5: Let It Rest

Once it’s out of the oven, let it rest for 5–10 minutes before serving. This lets it thicken slightly, so every spoonful comes out creamy and perfect. Garnish with a sprinkle of fresh thyme or chopped parsley if you’re feeling fancy.

Tips for the Best French Onion Chicken Orzo Casserole

• Add veggies: Mushrooms, spinach, or even kale work beautifully in this dish.
• Use rotisserie chicken: Save time and skip the browning step.
• Make ahead: Assemble everything, refrigerate, then bake when ready.
• Cheese swap: Mozzarella or provolone can stand in for Gruyère if needed.
• Storage: Leftovers keep well for up to 3 days in the fridge. Reheat with a splash of broth or cream.

Don’t panic if your onions take a little longer to caramelize—it’s totally normal and absolutely worth the wait.
