# How to Make It:

01 - Preheat the oven to 350°F. Grease a 9x13-inch baking dish.
02 - Heat olive oil in a large skillet over medium heat. Add onion and garlic, sautéing for 2 to 3 minutes until fragrant.
03 - Add mushrooms, carrot, celery, and red bell pepper to the skillet. Cook for 5 to 7 minutes until softened and mushrooms release their liquid.
04 - Stir in chopped spinach, thyme, rosemary, salt, and black pepper. Cook for 1 minute until spinach wilts.
05 - In the prepared baking dish, combine wild rice, sautéed vegetables, vegetable broth, and water. Mix thoroughly.
06 - Cover the dish tightly with foil and bake for 1 hour, or until the rice is tender and most liquid is absorbed.
07 - If using cheese, remove foil, sprinkle cheese evenly on top, and bake uncovered for an additional 10 minutes until golden and melted.
08 - Allow the casserole to rest for 5 minutes before serving.

# Expert Suggestions:

01 -
  • It comes together in under 20 minutes of actual hands-on work, then the oven does all the heavy lifting while you relax.
  • One dish feeds a crowd without requiring you to hover over the stove, which means you can actually enjoy your guests.
  • The earthiness of mushrooms and wild rice feels substantial enough for a main course, but works perfectly as a side dish too.
02 -
  • Rinse your wild rice before cooking; nobody wants a gummy casserole, and this one small step is the difference between creamy and mushy.
  • Don't skip the sauté step—cooking the vegetables first means they release moisture and develop flavor instead of steaming inside the casserole.
  • Wild rice takes longer to cook than regular rice, so the 1 hour baking time is actually crucial; rushing this will leave you with crunchy rice that nobody enjoys.
03 -
  • Slice mushrooms while the onion is cooking so you're not scrambling at the last minute; mise en place makes everything smoother.
  • Toast the wild rice in a dry skillet for 2 minutes before cooking if you want to deepen its nutty flavor and make it taste more intentional.
