How to Make French Onion Chicken Orzo Casserole
Follow these simple steps to prepare this delicious French Onion Chicken Orzo Casserole:
Step 1: Prepare the Slow Cooker
In the bowl of your slow cooker, layer the sliced onions and 3 tablespoons of butter. Place the chicken on top and drizzle with thyme, sage, minced garlic, salt, and pepper. Pour in the white wine and broth, then add the mushrooms. Cover and cook on low for 3-4 hours or high for 1-2 hours.
Step 2: Broil the Chicken and Onions
Once the chicken is tender, preheat your broiler to high. Carefully remove the chicken and most of the onions from the slow cooker and transfer them to a baking sheet.
Step 3: Cook the Orzo
Turn your slow cooker to high, stir in the dry orzo, and add 1 cup of water. Cover and cook for 20-30 minutes, or until the orzo is al dente. If it looks a bit dry, add a splash more water.
Step 4: Create Creamy Goodness
Stir in the heavy cream and the parmesan cheese, mixing well to combine all that creamy goodness, letting it meld together beautifully.
Step 5: Melt the Cheese
Arrange the remaining butter over the onions on the baking sheet, then sprinkle the gruyere cheese on top. Broil for 3-5 minutes until the cheese is melty and bubbling with that delightfully golden crust.
Step 6: Serve and Enjoy
Spoon the creamy orzo mixture onto a plate, then pile on the chicken and caramelized onions. It’s the perfect dish for impressing guests or indulging in some cozy comfort food goodness all by yourself.
