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 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)
Directions
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.
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.
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.
Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.
Bake the Casserole: Preheat 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.
Serve: Let it rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.
How to Serve French Onion Chicken Orzo Casserole
Serving this dish can be quite easy. You can spoon it right from the casserole into bowls or plates. It goes well with a simple side salad to add some crunch. You can also serve it with crusty bread or garlic bread. This will help to soak up the creamy sauce.
For a more filling meal, you can add steamed vegetables, like green beans or broccoli, on the side. If you want to keep things easy, a store-bought salad works just fine too.
How to Store French Onion Chicken Orzo Casserole
To store any leftovers, let the casserole cool down completely. Then, place it in an airtight container. It will keep in the refrigerator for about 3-4 days. Make sure to reheat it in the oven or microwave before serving.
If you have more leftovers than you can eat, consider freezing them. You can freeze the casserole for up to 2-3 months. It’s best to store it in individual portions for easy reheating. To reheat, thaw in the refrigerator overnight and warm it up in the oven or microwave until heated through.
Tips to Make French Onion Chicken Orzo Casserole
Using rotisserie chicken makes this dish even quicker to prepare. You can also caramelize onions ahead of time if you’re short on cooking time later.
If you want more flavor, consider adding herbs like rosemary or herbs de Provence. Adjust the seasonings to your taste. For an earthy flavor, try adding mushrooms along with the onions.
Remember to stir occasionally while cooking to prevent sticking. If you like a crispy top, you can broil the casserole for a minute or two after baking. Just watch it closely to avoid burning.
Variation
Feel free to swap out the chicken for cooked sausage or another protein. You can also try using a different type of pasta. Whole wheat or gluten-free orzo can work well too. If you want a vegetarian version, use vegetables like diced bell peppers or zucchini instead of chicken.
For a spicier kick, you can add red pepper flakes or diced jalapeño. If you prefer a lighter dish, try using half and half instead of heavy cream.
