- Shredded Swiss Cheese: Melts beautifully and gives that classic French onion taste; don’t skimp!

How to Make French Onion Chicken Orzo Casserole
Preheat oven to 375°F (190°C). Grease a baking dish with nonstick spray to prevent sticking later on. Season both sides of chicken breasts with salt and pepper.
Sauté Your Onions: In a large skillet over medium heat, melt butter and add sliced onions. Cook until they turn translucent and fragrant—about 10 minutes.
Add Garlic & Chicken: Stir in minced garlic and continue cooking for another minute until aromatic. Add chicken breasts into the skillet, searing them on both sides until lightly browned.
Combine with Orzo: Pour in chicken broth along with uncooked orzo pasta. Bring to a gentle simmer while stirring frequently—this ensures nothing sticks to the bottom!
Mix in Sour Cream & Thyme: Once orzo has absorbed most of the broth (about 10 minutes), stir in sour cream and thyme leaves for that creamy goodness everyone loves.
Top with Cheese & Bake: Transfer mixture into your prepared baking dish. Sprinkle generously with shredded Swiss cheese on top before popping it into your preheated oven.
Bake Until Golden Brown: Bake uncovered for 25-30 minutes until bubbly and golden brown on top. Allow it to cool slightly before serving so you don’t burn your tongue trying to taste it right away!
And there you have it—a dreamy French Onion Chicken Orzo Casserole that’s sure to elevate any dinner occasion whether it’s just another Tuesday or a special celebration!
