Step-by-Step Instructions

Let’s make it together! Follow these steps to create your French Onion Chicken Orzo Casserole:

1. Caramelize the Onions: In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add the sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally, until the onions are deeply golden and caramelized. Stir in the minced garlic during the last 1–2 minutes.

2. Add Orzo and Chicken: Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Add the shredded chicken, thyme, pepper, and Worcestershire sauce if using. Mix well.

3. Pour in Liquids: Add the chicken broth and cream. Bring to a gentle simmer. Reduce heat to low, cover, and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender.

4. Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.

5. Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top. Bake uncovered for 10–15 minutes until bubbly and golden on top.

6. Serve: Let it rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Chef Emma’s Helpful Tips

To ensure your casserole turns out perfect every time, consider these helpful tips:

• Make-Ahead: Prep the casserole in advance by cooking the onions and mixing everything together. Store it in the fridge and bake it just before serving.

• Ingredient Swaps: If you’re running low on chicken, try using turkey or even sautéed tofu for a vegetarian option.

• Onion Slicing Trick: For perfectly thin slices, use a mandoline slicer, which saves time and ensures even cooking.

• Proper Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
