3. Step-by-step Instructions for this Chicken Casserole Recipe

Preparation of Caramelized Onions

Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions and cook gently, stirring occasionally, until they become soft and golden brown. For extra flavor, add 2 tablespoons of balsamic vinegar and cook for another 10 minutes. Set aside.

Cooking the Chicken

In a separate large skillet, heat another tablespoon of olive oil. Season the diced chicken with salt, pepper, and thyme. Cook until the chicken is browned and cooked through, about 8-10 minutes. Remove from heat and set aside.

Cooking the Orzo

In a saucepan, bring chicken broth to a boil. Add the orzo and cook until al dente, according to package instructions. Drain any excess liquid if necessary.

Assembling the Baked Casserole

Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the cooked chicken, orzo, caramelized onions, minced garlic, and seasoning. Mix well. Transfer the mixture to a greased baking dish.

Adding Cheese and Baking

Top the casserole with shredded cheese, spreading evenly. Bake uncovered for 20-25 minutes until the cheese is bubbly and golden. For an extra cheesy topping, broil for 2-3 minutes until browned.

4. Storage Tips for Leftover Baked Chicken Casserole

Allow the casserole to cool completely before storing. Place leftovers in an airtight container and keep in the refrigerator for up to 3 days. Reheat in the oven or microwave until heated through for best texture and flavor. For longer storage, you can freeze the casserole for up to 2 months.
