Ingredients

You don’t need fancy stuff — just these basics!

• 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 a lighter option)
• 1 1/2 cups shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze

Directions

1. In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally, until onions are deeply golden and caramelized. Stir in minced garlic during the last 1–2 minutes.
2. Stir in the orzo and cook for 2 minutes to allow it to lightly toast. Add shredded chicken, thyme, pepper, and Worcestershire if using. Mix well.
3. 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.
4. Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.
5. 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.
6. Let it rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

FAQs

• Can I use uncooked orzo? Yes, you can, but cook it a little longer with the broth to ensure it’s fully soft.
• What if I don’t have rotisserie chicken? No worries! Any cooked chicken works just fine. You could even use shredded turkey for a post-holiday dish!
