  • Total Time: 1 hour
  • Yield: 6

Ingredients

  • 3 cups cooked chicken (rotisserie or shredded chicken breast)

  • 1½ cups uncooked orzo pasta

  • 1 (10.5 oz) can cream of chicken soup (or homemade)

  • 1 cup sour cream or French onion dip

  • 2½ cups chicken broth (low-sodium recommended)

  • 2 tsp onion powder

  • 1 tsp garlic powder

  • ½ tsp salt (adjust to taste)

  • ½ tsp black pepper

  • 3 cups shredded cheddar cheese (or Gruyère for extra flavor)

  • 1 (6 oz) can French fried onions, divided

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.

  2. In a large bowl, whisk together cream of chicken soup, sour cream (or French onion dip), chicken broth, and seasonings.

  3. Stir in uncooked orzo, shredded chicken, half of the cheese, and half of the fried onions.

  4. Pour mixture into the baking dish.

  5. Top with remaining cheese and fried onions.

  6. Cover the dish with foil and bake for 25 minutes.

  7. Uncover and bake another 10–15 minutes until bubbly and golden brown.

  8. Remove from oven and let rest 5–10 minutes before serving.

Notes

  • Orzo tip: No need to cook orzo beforehand — it absorbs flavor directly in the oven.

  • Cheese swap: Use Gruyère or Swiss cheese for a French onion twist.

  • Make-ahead: Assemble up to a day in advance and refrigerate until ready to bake.

  • Storage: Keeps up to 3 days in the fridge; reheat at 350°F for 15 minutes.

  • Freezing: Cool completely, wrap tightly, and freeze up to 3 months.
