Ingredients

  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 large yellow onions (thinly sliced)
  • 1 teaspoon sugar
  • 1/2 teaspoon salt
  • 3 garlic cloves (minced)
  • 1 1/2 cups orzo pasta
  • 2 cups cooked shredded chicken (rotisserie works well)
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon black pepper
  • 2 cups low-sodium chicken broth
  • 1 cup heavy cream (or half and half for a lighter option)
  • 1 1/2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze (for added depth)

Step-by-Step Instructions

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 approximately 20 to 25 minutes while stirring occasionally. The goal is to achieve a deeply golden and caramelized color. For the last 1 to 2 minutes, incorporate the minced garlic for added flavor.

Add Orzo and Chicken

Stir in the orzo and cook for about 2 minutes to give it a light toasting. Next, add the shredded chicken, dried thyme, black pepper, and Worcestershire sauce if you use it. Mix thoroughly to combine all the ingredients.

Pour in Liquids

Pour in the chicken broth and heavy cream. Bring the mixture to a gentle simmer. Once bubbling, reduce the heat to low, cover, and allow it to cook for about 8 to 10 minutes. Stir occasionally until the orzo is tender to your liking.

Add Cheese

Gently mix in 1 cup of the mozzarella and the grated Parmesan cheese until they melt and create a creamy texture throughout the mixture.

Bake the Casserole

Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top of the casserole. Bake it uncovered for about 10 to 15 minutes or until it becomes bubbly and golden on top.

Serve

Once baked, allow the casserole to sit for about 5 to 10 minutes before serving. For an extra touch, garnish with fresh thyme or parsley.

Pro Tips and Variations

  • Swap Proteins: Substitute shredded chicken with cooked ground turkey or chickpeas for a vegetarian version.
  • Add Vegetables: Mix in spinach or bell peppers for added color and nutrition.
  • Use Different Cheeses: Experiment with Gruyere or Gouda for different flavor profiles.
  • Herb Variations: Try using fresh herbs like rosemary or parsley for enhanced freshness.
  • Texture: For a crunchy topping, add panko breadcrumbs mixed with olive oil before baking.

How to Serve French Onion Chicken Orzo Casserole

This delightful casserole can shine as a standalone dish, but it pairs wonderfully with a side salad or steamed vegetables to balance the richness. You could also serve it alongside crusty bread for those who wish to soak up the gorgeous creamy sauce. For a refreshing twist, consider a light vinaigrette salad to accompany this warm comfort dish.

How to Store French Onion Chicken Orzo Casserole

Leftover casserole can be stored in an airtight container in the fridge for up to 4 days. If you want to keep it longer, consider freezing it. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) until warmed through, about 20-25 minutes. You might want to cover it with foil to keep it from drying out.
