Description

A heartwarming casserole that combines the rich essence of French onion soup with the satisfying bite of orzo, topped with golden cheese.


Ingredients

  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon sugar
  • ½ teaspoon salt
  • 3 garlic cloves, minced
  • 1 ½ cups orzo pasta
  • 2 cups cooked shredded chicken (rotisserie works well)
  • ½ teaspoon dried thyme
  • ¼ teaspoon black pepper
  • 2 cups low-sodium chicken broth
  • 1 cup heavy cream (or half and half for a lighter option)
  • 1 ½ cups shredded mozzarella cheese
  • ½ cup grated Parmesan cheese
  • Optional: ½ teaspoon Worcestershire sauce or balsamic glaze


Instructions

  1. 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 until the onions are deeply golden and caramelized, adding minced garlic in the last 1-2 minutes.
  2. Stir in the orzo, toasting it lightly for about 2 minutes. Add the shredded chicken, thyme, and pepper, and mix well.
  3. Add the chicken broth and cream, bringing the mixture to a gentle simmer. Reduce the heat to low, cover, and cook for 8-10 minutes, stirring occasionally until the orzo is tender.
  4. Stir in 1 cup of mozzarella and the grated Parmesan cheese until fully melted and creamy.
  5. Preheat your oven to 375°F (190°C). Sprinkle the remaining ½ cup of mozzarella over the top and bake uncovered for 10-15 minutes, until bubbly and golden.
  6. Let the casserole rest for 5-10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Notes

Feel free to substitute the chicken with your favorite protein or make it vegetarian using plant-based ingredients. For extra flavor, try adding sautéed mushrooms or spinach.

Best Ways to Enjoy It

To elevate your French Onion Chicken Orzo Casserole, consider serving it with a side salad tossed in a light vinaigrette. A crusty baguette pairs beautifully, perfect for scooping up any creamy leftovers. For those looking to add a touch of freshness, sliced avocado or a dollop of sour cream can enhance each bite.

How to Store & Freeze

Storing this casserole is straightforward. Simply let it cool completely before transferring it to an airtight container. It will keep well in the refrigerator for up to 3 days. If you want to freeze leftovers, ensure they are in a freezer-safe container; they can last up to 2 months. Reheat in the oven at 350°F (175°C) until warmed through.

Helpful Cooking Tips

  • For perfectly caramelized onions, resist the urge to rush the process. Cooking them on medium heat and stirring occasionally will yield the best results.
  • If you’re short on time, using pre-chopped onions or frozen shredded chicken can save you valuable minutes.
  • Experiment with herbs and spices; adding a pinch of nutmeg or a dash of hot sauce can provide an exciting twist that personalizes the dish.

Creative Twists

Feel like getting adventurous? Try incorporating sautéed mushrooms or spinach for added flavor and nutrition. For a different flavor profile, swap mozzarella for gruyere cheese, which adds a wonderfully nutty taste. If you want to make it lighter, opt for cauliflower or whole wheat orzo.
