How to Make Chicken Wild Rice Casserole (Step-by-Step)
1. Sear Chicken & Sauté Veggies: In a large skillet or cast iron pan over medium-high heat, melt 1 tablespoon of butter. Add the diced chicken seasoned with salt and pepper, cooking for 5 minutes until lightly golden. Add the sliced mushrooms, carrots, celery, diced onion, and garlic. Sauté for 5 minutes until veggies soften.
2. Whisk Velvety Cream Sauce: In a saucepan over medium heat, melt 2 tablespoons of butter and whisk in 3 tablespoons of flour for 1 minute. Slowly whisk in the chicken broth and heavy cream until completely smooth. Stir in Dijon mustard, fresh thyme, Parmesan, and black pepper. Simmer for 3 minutes until thickened and velvety.
3. Combine in Baking Dish: Preheat oven to 375°F (190°C). Grease a 9×13-inch ceramic baking dish. Add the cooked wild rice blend, seared chicken, sautéed vegetables, and pour the warm cream sauce over the top. Toss gently with a wooden spoon until everything is evenly coated.
4. Bake until Bubbly & Golden: Sprinkle the top with shredded Gruyère or white cheddar cheese. Bake uncovered for 25 to 30 minutes until bubbling around the edges and golden brown on top. Garnish with chopped fresh parsley and serve hot!
