Ingredients

Scale
  • 1 cup (200g) wild rice blend
  • 2 cups (480ml) vegetable broth
  • 8 ounces (225g) fresh mushrooms (Cremini or button, or mix with shiitake or portobello)
  • 4 tablespoons unsalted butter (divided)
  • 2 cloves garlic, minced
  • 1 yellow onion, diced
  • 1 cup (240ml) heavy cream
  • 1 cup (100g) Gruyère cheese, freshly grated
  • 1 teaspoon fresh thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • Additional Gruyère cheese (about 1/4 cup or 25g) for topping

Instructions

  1. Cook the wild rice: In a medium saucepan, combine 1 cup (200g) of wild rice blend with 2 cups (480ml) of vegetable broth. Bring to a boil, then reduce to a simmer. Cover and cook for 40-45 minutes, or until the rice is tender and liquid is absorbed. Set aside.
  2. Preheat the oven: Preheat your oven to 375°F (190°C).
  3. Sauté the mushrooms: Heat 2 tablespoons of unsalted butter in a large skillet over medium heat. Add 8 ounces (225g) of sliced mushrooms and cook for 5-7 minutes, stirring occasionally, until golden and tender. Remove from the skillet and set aside.
  4. Sauté the aromatics: In the same skillet, add 2 tablespoons of butter, 1 diced yellow onion, and 2 cloves of minced garlic. Cook for 3-4 minutes until softened and fragrant.
  5. Make the creamy sauce: Reduce heat to low and stir in 1 cup (240ml) of heavy cream. Add 1 cup (100g) of freshly grated Gruyère cheese and stir until melted and smooth. Season with 1 teaspoon of fresh thyme, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper.
  6. Combine ingredients: In a large mixing bowl, combine the cooked wild rice, sautéed mushrooms, and creamy sauce. Mix until evenly combined.
  7. Assemble the casserole: Transfer the mixture to a greased 9×13-inch baking dish. Spread evenly and sprinkle additional Gruyère cheese (about 1/4 cup or 25g) on top.
  8. Bake: Bake in the preheated oven for 20-25 minutes, or until the top is golden and bubbly.
  9. Cool and serve: Let the casserole rest for 5 minutes before serving. Garnish with fresh thyme if desired.
