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)

Instructions

1. Step 1: 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.
2. Step 2: Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Add the shredded chicken, dried thyme, black pepper, and Worcestershire sauce or balsamic glaze if using. Mix well.
3. Step 3: Pour in the chicken broth and heavy cream. Bring to a gentle simmer, then reduce the heat to low. Cover and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender.
4. Step 4: Stir in 1 cup of the shredded mozzarella cheese and all of the Parmesan cheese. Mix until the cheeses are melted and creamy.
5. Step 5: Preheat the oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella over the top of the casserole. Bake uncovered for 10–15 minutes until bubbly and golden on top.
6. Step 6: Remove from the oven and let the casserole rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

For the Onion Base

• 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

Main Ingredients

• 1 1/2 cups orzo pasta
• 2 cups cooked shredded chicken (rotisserie recommended)
• 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)

Cheese & Optional

• 1 1/2 cups shredded mozzarella cheese (divided into 1 cup and 1/2 cup portions)
• 1/2 cup grated Parmesan cheese
• Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze

Instructions

1. Caramelize the Onions: In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add the thinly sliced onions, sugar, and salt. Cook slowly for 20 to 25 minutes, stirring occasionally, until the onions turn deeply golden and caramelized. Add the minced garlic during the last 1 to 2 minutes, stirring to combine and release its aroma.
2. Add Orzo and Chicken: Stir in the orzo pasta and cook for about 2 minutes to lightly toast it, which enhances its flavor. Then add the cooked shredded chicken, dried thyme, black pepper, and if using, Worcestershire sauce or balsamic glaze. Mix well to combine all ingredients thoroughly.
3. Pour in Liquids: Pour the low-sodium chicken broth and heavy cream into the skillet. Bring the mixture to a gentle simmer over medium heat, then reduce the heat to low. Cover the skillet and let it cook for 8 to 10 minutes, stirring occasionally, until the orzo is tender and has absorbed most of the liquids.
4. Add Cheese: Stir in 1 cup of shredded mozzarella and the grated Parmesan cheese. Mix until the cheeses melt into a creamy sauce, coating the pasta and chicken evenly.
5. Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup shredded mozzarella evenly over the top of the casserole. Place the skillet uncovered in the oven and bake for 10 to 15 minutes or until the cheese on top is bubbly and golden brown.
6. Serve: Remove the casserole from the oven and let it rest for 5 to 10 minutes to set. Garnish with fresh thyme or parsley if desired before serving to add a fresh herbal touch.
