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

Step-by-Step Instructions
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 until caramelized, stirring occasionally. In the last 1-2 minutes, stir in the minced garlic.

Tips & Tricks for Success

Ingredient Swaps
- Noodles: Try replacing orzo with any pasta you have on hand, like penne or rotini.
- Cream: For a lighter touch, opt for low-fat cream or Greek yogurt.
