Method

Step-by-Step Instructions

In a large oven-safe skillet, melt butter with olive oil over medium heat. Add sliced yellow onions, granulated sugar, and kosher salt. Cook for 20-25 minutes, stirring occasionally, until caramelized.
Stir in minced garlic and cook for an additional 2 minutes.
Add orzo pasta to the skillet, stirring to combine. Toast for about 2 minutes until slightly golden.
Mix in cooked shredded chicken, dried thyme, and black pepper. Add Worcestershire sauce or balsamic glaze if desired.
Pour in chicken broth and heavy cream, bringing to a gentle simmer. Cook for 8-10 minutes until orzo is tender.
Reduce heat to low and stir in mozzarella cheese and grated Parmesan until melted and creamy.
Preheat your oven to 375°F (190°C). Transfer the skillet to the oven and top with remaining mozzarella cheese. Bake for 10-15 minutes until bubbly and golden brown.
Let the casserole rest for 5-10 minutes before serving. Garnish with fresh herbs if desired.
