Ingredients
- 1 cup wild rice
- 2 1/2 cups water
- 2 tbsp olive oil
- 8 oz cremini mushrooms, sliced
- 1 medium yellow onion, diced
- 3 garlic cloves, minced
- 1 tsp salt

- 1 cup shredded sharp cheddar cheese
- 1/2 cup sour cream
- 1 tsp fresh thyme leaves
- 1/2 cup breadcrumbs
- 2 tbsp butter, melted
Instructions
- Step 1: Preheat oven to 375°F. In a medium saucepan, bring 2 1/2 cups water to a boil. Add 1 cup wild rice, reduce heat to low, cover, and simmer for 45 minutes until tender and water is absorbed.
- Step 2: While rice cooks, heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 medium diced yellow onion and sauté for 4 minutes until translucent. Add 8 oz sliced cremini mushrooms and 3 minced garlic cloves, cooking for an additional 6 minutes until mushrooms release moisture and edges brown.
- Step 3: Stir in 1 tsp salt, 1/2 tsp black pepper, and 1 tsp fresh thyme leaves into the mushroom mixture, cooking for 1 minute until fragrant.
- Step 4: In a large mixing bowl, combine the cooked wild rice, mushroom mixture, 1 cup shredded sharp cheddar cheese, and 1/2 cup sour cream. Mix until evenly incorporated.
- Step 5: Transfer the mixture to a greased 8x8 inch baking dish. In a small bowl, mix 1/2 cup breadcrumbs with 2 tbsp melted butter, then sprinkle evenly over the casserole.
- Step 6: Bake uncovered for 25 minutes until the top is golden brown and cheese is bubbling. Let rest for 5 minutes before serving.
