Ingredients

Scale

Chicken and Onion Base

  • 3-4 yellow onions, thinly sliced
  • 6 tablespoons salted butter, divided
  • 1 1/2 pounds boneless chicken breasts or thighs
  • 2 tablespoons fresh thyme leaves
  • 2 tablespoons chopped fresh sage
  • Kosher salt and black pepper, to taste
  • 3 cloves garlic, chopped
  • 1 cup dry white wine
  • 1 cup chicken or vegetable broth
  • 2 cups sliced mushrooms

Orzo and Cheese

  • 2 cups dry orzo pasta
  • 1/2 cup heavy cream
  • 1/2 cup grated parmesan cheese
  • 1 cup shredded Gruyere cheese


Instructions

  1. Slow Cook the Chicken and Onions: In the bowl of your slow cooker, layer the thinly sliced onions and 3 tablespoons of salted butter, followed by placing the chicken breasts or thighs on top. Sprinkle fresh thyme leaves, chopped sage, chopped garlic, salt, and pepper over the chicken evenly. Pour the dry white wine and chicken or vegetable broth over everything, then add the sliced mushrooms. Cover and cook on low for 3-4 hours or on high for 1-2 hours until the chicken becomes tender and cooked through.
  2. Prepare the Orzo on High Heat: Remove the chicken and most of the caramelized onions from the slow cooker and place them on a baking sheet. Increase the slow cooker setting to high. Stir in the dry orzo pasta along with 1 cup of water, then cover and let it cook for 20-30 minutes. Check occasionally for doneness, adding more water if the orzo requires additional liquid. Once the orzo is al dente, stir in the heavy cream and grated parmesan cheese to achieve a creamy consistency.
  3. Broil with Gruyere Cheese: Spread the reserved onions over the chicken on the baking sheet. Dot with the remaining 3 tablespoons of butter and generously sprinkle shredded Gruyere cheese over the top. Place the baking sheet under a preheated broiler for 3-5 minutes, watching carefully until the Gruyere cheese melts and is lightly browned and bubbly.
  4. Serve: Plate the creamy orzo and top with the broiled chicken and onion mixture immediately. Enjoy this rich and savory dish while hot for the best flavor experience.

Notes

  • Use boneless chicken thighs for more tender and flavorful meat, or chicken breasts if you prefer leaner protein.
  • If you don’t have dry white wine, substitute with additional chicken broth and a splash of lemon juice for acidity.
  • Keep an eye on the orzo during cooking to prevent sticking and add water as necessary.
  • Gruyere cheese browns nicely under the broiler; do not leave unattended to avoid burning.
  • This dish can be made a day ahead; refrigerate and reheat gently before serving.
