Ingredients

Ingredients

For the Casserole

  • 2 large onions, thinly sliced

Instructions

Instructions

Preheat and Cook Onions

Preheat your oven to 375°F (190°C). In a large skillet, heat olive oil over medium heat. Add the sliced onions and cook until they are caramelized, about 15-20 minutes.

Prepare the Chicken

While the onions are cooking, season the chicken with salt and pepper. Once the onions are ready, push them to the side and add the chicken to the skillet. Sear for about 5 minutes on each side until golden brown.

Combine Everything

In a large bowl, combine the cooked orzo, caramelized onions, chicken broth, and half of the mozzarella cheese. Mix until well combined. Place the chicken on top and sprinkle with remaining cheese.

Bake the Casserole

Transfer the mixture to a baking dish and cover with foil. Bake for 30 minutes. Remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and golden.

Let it cool for a few minutes before serving to allow the casserole to set.

Serving Suggestions

When serving your French Onion Chicken Orzo Casserole, consider pairing it with a light green salad or some crusty bread for a complete meal. The freshness of a salad can balance the richness of the casserole, making for a well-rounded dish. A sprinkle of fresh thyme or parsley on top can also add a pop of color and freshness.

For those who enjoy a bit of heat, serving with a side of chili flakes or hot sauce can elevate the flavor profile and add an exciting twist. This meal is all about comfort, so feel free to customize the accompaniments to suit your family’s preferences.

Storage Tips

When it comes to storing leftovers, allow the casserole to cool completely before transferring it to airtight containers. This will help preserve its flavor and texture. You can keep it in the refrigerator for up to 3-4 days or freeze it for longer storage. To freeze, make sure it is well-wrapped to prevent freezer burn, and use it within three months.

Reheating is straightforward—just consider adding a splash of water or extra chicken broth to keep the orzo from drying out. This handy casserole not only makes for delicious leftovers but is also a great make-ahead option for gatherings and busy weeknights.
