Step-by-Step Instructions
1. Cook the Wild Rice
In a medium saucepan, combine the wild rice blend and vegetable broth. Bring to a boil, then reduce heat, cover, and simmer for 40-45 minutes, or until the rice is tender. Drain any excess liquid and set aside.
2. Sauté the Vegetables
While the rice cooks, heat olive oil in a large skillet over medium heat. Add the chopped onion and celery, cooking until softened, about 5-7 minutes. Stir in the sliced mushrooms and cook until they release their liquid and begin to brown, another 5-7 minutes.
3. Create the Sauce Base
Sprinkle the flour over the cooked vegetables, stirring for one minute to coat. Gradually whisk in the milk until no lumps remain and the mixture thickens slightly. Stir in the dried thyme and garlic powder, seasoning with salt and pepper.
4. Combine and Assemble
Remove the skillet from the heat. Gently fold in the cooked wild rice and shredded chicken into the vegetable and sauce mixture. Transfer this mixture to your greased 9×13 inch baking dish, spreading it evenly.
5. Bake the Casserole
If using, sprinkle the shredded cheddar cheese over the top of the casserole. Bake in a preheated oven at 375°F (190°C) for 20-25 minutes, or until bubbly and heated through. Garnish with fresh parsley if you desire.
Variation Ideas
- Add a cup of frozen peas or corn during the last 5 minutes of sautéing the vegetables.
- Swap out cheddar cheese for Gruyère or Parmesan cheese for a different flavor profile.
- Incorporate a pinch of dried sage for an earthier taste.
- For a richer texture, you can add a dollop of plain Greek yogurt to the sauce.

You can store leftover Wild Rice and Mushroom Chicken Casserole in an airtight container in the refrigerator for up to 3-4 days. To reheat, warm individual portions in the microwave or cover and bake in a preheated oven at 300°F (150°C) until heated through.
