Ingredients

Scale
  • 2 cups cooked, shredded chicken
  • 1 cup uncooked long grain white rice
  • 1 (10.5 oz) can French onion soup
  • 1 (10.5 oz) can cream of chicken soup
  • 1 1/2 cups shredded Swiss or mozzarella cheese
  • 1/2 cup milk
  • 1 tablespoon butter
  • 1 small onion, thinly sliced

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish.
  2. In a skillet, melt butter over medium heat. Add sliced onions and sauté until caramelized, about 10–12 minutes. Set aside.

  • Swap Swiss cheese for Gruyère for extra richness.
  • Add sautéed mushrooms or green beans for additional texture and nutrients.
