Ingredients
  

For the Casserole
  • 2 tablespoons Unsalted Butter Adds richness and aids in caramelizing onions; substitute with olive oil for a lighter version.
  • 2 tablespoons Olive Oil Used for sautéing alongside butter; can be replaced with additional butter if desired.
  • 3 medium Yellow Onions Provide the sweet base flavor through caramelization; opt for sweet onions for best results.
  • 1 teaspoon Sugar Enhances the caramelization of onions; optional, can be omitted.
  • 1 teaspoon Salt Balances flavors throughout the dish; adjust to taste.
  • 2 cloves Garlic Adds aromatic depth; can substitute with garlic powder if fresh is unavailable.
  • 1 cup Orzo Pasta Absorbs flavors and creaminess well; ensure it's cooked slightly under for best texture when baking.
  • 2 cups Cooked Shredded Chicken A protein source; rotisserie chicken offers a quick, convenient option.
  • 1 teaspoon Dried Thyme Enhances the savory profile; fresh thyme can give a brighter taste.
  • 1 teaspoon Black Pepper Adds seasoning; increase amount for more heat.
  • 1 cup Low-Sodium Chicken Broth Adds depth and flavor; homemade broth is ideal for the best taste.
  • 1 cup Heavy Cream Creates a rich, creamy sauce; half-and-half can be used for a lighter alternative.
  • 1 cup Shredded Mozzarella Cheese Melts beautifully for creaminess; Gruyère offers a more authentic flavor option.
  • 1/4 cup Grated Parmesan Cheese Provides depth and a salty edge to the dish.
For Variations
  • 1 cup Cooked Bacon Stir in for a smoky flavor boost.
  • 2 cups Sautéed Spinach Add for added nutrition and color.
  • 1 teaspoon Crushed Red Pepper Flakes Mix in for an extra kick of heat.
  • 2 cups Cauliflower Rice Use instead of orzo for a low-carb option, adjusting cooking times as needed.

Equipment

  • large oven-safe skillet
  • Medium Skillet

Method
 

Step-by-Step Instructions
  1. In a large oven-safe skillet, melt 2 tablespoons of unsalted butter with 2 tablespoons of olive oil over medium heat. Add 3 sliced yellow onions, 1 teaspoon of sugar, and 1 teaspoon of salt. Cook for 30-40 minutes, stirring frequently, until the onions are golden brown and caramelized. In the last minute, stir in 2 minced garlic cloves for added flavor.
  2. While the onions caramelize, heat another skillet over medium-high heat, adding 2 cups of cooked shredded chicken seasoned with salt and pepper. Sear the chicken for about 5-7 minutes until it’s golden on the outside.
  3. Once the onions are caramelized, pour 1 cup of low-sodium chicken broth into the skillet, stirring to deglaze and lift all the delicious browned bits. Add 1 cup of orzo pasta, 1 cup of heavy cream, 1 teaspoon of dried thyme, and the browned chicken. Let it simmer for 3-5 minutes.
  4. Preheat your oven to 375°F (190°C). Stir in half of 1 cup of shredded mozzarella cheese into the mixture until melted. Sprinkle the remaining mozzarella on top, along with 1/4 cup of grated Parmesan cheese. Transfer the skillet to the oven and bake for 20-25 minutes.
  5. Once out of the oven, allow your casserole to cool for about 5-10 minutes. Garnish with fresh herbs for a delightful touch and serve warm.
