2 large onions, thinly sliced
3 cloves garlic, minced

Salt and pepper to taste

3. Step-by-Step Instructions for Making French Onion Chicken Orzo Bake

Step 1: Caramelize the Onions

Heat 1 tablespoon of olive oil and butter in a large skillet over medium heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until onions are golden brown and caramelized, about 20-25 minutes. This process develops the sweet, savory flavor that defines this dish.

Step 2: Prepare the Chicken

While the onions caramelize, season the diced chicken with salt, pepper, thyme, and rosemary. In a separate skillet, cook the chicken in a tablespoon of olive oil until browned and cooked through. Set aside.

Step 3: Cook the Orzo Pasta

In a pot of boiling salted water, cook the orzo according to package instructions until al dente. Drain and set aside.

Step 4: Combine Ingredients

Preheat your oven to 375°F (190°C). In a large mixing bowl, combine cooked orzo, caramelized onions, cooked chicken, and garlic. Mix well to distribute all ingredients evenly.

Step 5: Assemble the Bake

Transfer the mixture to a greased baking dish. Pour chicken broth over the mixture to keep everything moist. Top with shredded cheese for that irresistible cheesy crust.

Step 6: Bake and Broil

Bake uncovered for 20-25 minutes until bubbly and golden on top. For extra crispiness, broil for an additional 2-3 minutes, watching carefully to prevent burning.

4. Storage Tips for Leftover French Onion Chicken

Let the leftovers cool completely, then store them in an airtight container in the refrigerator for up to 3 days. To reheat, microwave in short bursts or warm in the oven until heated through. This dish can also be frozen in portions for up to 2 months—just be sure to thaw thoroughly before reheating.
