# What You Need:

→ Grains

01 - 1 cup wild rice, rinsed
02 - 2 cups vegetable broth (gluten-free, if needed)
03 - 1 cup water

→ Vegetables

04 - 2 tablespoons olive oil
05 - 1 medium yellow onion, finely chopped
06 - 2 garlic cloves, minced
07 - 2 cups cremini or white mushrooms, sliced
08 - 1 medium carrot, diced
09 - 1 celery stalk, diced
10 - 1 red bell pepper, diced
11 - 1 cup fresh spinach, chopped

→ Seasonings

12 - 1 teaspoon dried thyme
13 - 1 teaspoon dried rosemary
14 - ½ teaspoon salt
15 - ¼ teaspoon black pepper

→ Dairy (optional)

16 - ½ cup grated Gruyère or Swiss cheese (optional, for topping)

# How To Make:

01 - Preheat the oven to 350°F. Grease a 9x13-inch baking dish with cooking spray or a small amount of oil.
02 - Heat olive oil in a large skillet over medium heat. Add chopped onion and minced garlic; sauté for 2–3 minutes until fragrant and translucent.
03 - Add sliced mushrooms, diced carrot, celery, and red bell pepper to the skillet. Cook for 5–7 minutes until vegetables are softened and mushrooms have released their moisture.
04 - Stir in chopped spinach, dried thyme, rosemary, salt, and black pepper. Cook for 1 minute until spinach is just wilted.
05 - Transfer wild rice to the prepared baking dish. Add sautéed vegetables, vegetable broth, and water. Mix thoroughly to distribute all ingredients evenly.
06 - Cover the baking dish tightly with aluminum foil. Bake for 1 hour, or until rice is tender and most liquid has been absorbed.
07 - If using cheese, remove foil and sprinkle grated cheese evenly over the top. Return to oven and bake uncovered for 10 minutes until melted and golden.
08 - Remove from oven and let casserole rest for 5 minutes before serving to allow flavors to settle.

# Expert Tips:

01 -
  • The wild rice creates this incredible nutty chewiness that makes it feel so much more special than regular rice dishes
  • Everything cooks in one pan before hitting the oven, meaning minimal cleanup and maximum flavor development
02 -
  • Wild rice takes longer to cook than regular rice, so don't rush that hour in the oven or you'll end up with crunchy, unpleasantly firm grains.
  • Check the liquid level at the 45-minute mark, and if it looks too dry, add a splash more water or broth.
03 -
  • Don't skip the foil during the initial baking time, or the wild rice will dry out before it's fully cooked.
  • Let the casserole rest for at least 5 minutes before serving—this simple step makes the difference between a cohesive dish and a sloppy mess.
