Step-by-Step Instructions:
1. Cook the Wild Rice
Begin by rinsing your wild rice blend thoroughly under cold water. Combine the rice with 2 cups of vegetable broth in a saucepan, bring to a boil, then reduce heat to low, cover, and simmer for 45-50 minutes, or until the rice is tender and the liquid is absorbed.
2. Sauté the Aromatics and Mushrooms
While the rice cooks, heat olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 5-7 minutes, then stir in the minced garlic and sliced mushrooms. Continue cooking until the mushrooms are tender and have released their liquid, about 8-10 minutes.
3. Combine Casserole Ingredients
In a large bowl, mix together the cooked wild rice, sautéed onion and mushrooms, cream of mushroom soup, milk, remaining 1 cup of vegetable broth, dried thyme, black pepper, and 1/2 cup of shredded cheddar cheese. Stir until all ingredients are well combined.
4. Bake the Casserole
Transfer the mixture to your prepared 9×13 inch baking dish. Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top. Bake for 25-30 minutes, or until bubbly and heated through, and the cheese is melted and lightly golden.
5. Serve and Enjoy
Remove the casserole from the oven and let it rest for a few minutes before serving. Garnish with fresh parsley if desired. This makes a delightful casserole dinner recipe for your family.

- Add Vegetables: Incorporate frozen peas, carrots, or green beans during the mixing step for extra nutrients.
