Ingredients for Wild Rice Casserole

  • Wild rice: As the casserole’s star ingredient, wild rice provides a nutty flavor. Wild rice is also healthy, as it’s rich in antioxidants and nutrient dense.
  • Mushrooms: Sliced button mushrooms add an earthy, umami-rich flavor and meaty texture to the dish.
  • Onion: Chopped onion lends a subtle sweetness to the base of the casserole.
  • Butter: Butter is used to saute the mushrooms and onion, adding richness to this wild rice casserole.
  • Long grain rice: A cup of uncooked long grain rice complements the wild rice and provides the dish with a varied texture.
  • Almonds: Sliced almonds provide a necessary crunch.
  • Chicken broth: The chicken broth infuses the rice as it cooks.
  • Heavy whipping cream: Heavy cream add a creamy, luxurious texture and helps to bind all the ingredients.
  • Parmesan cheese: Grated Parmesan cheese adds a salty, umami finish to this wild rice casserole.

Directions

Step 1: Soak the wild rice

Preheat the oven to 350°F. Place the uncooked wild rice in a large bowl and cover it with boiling water. Soak it for one hour, then drain and set aside.

Step 2: Saute the vegetables

In a large skillet, saute the mushrooms and onion in butter over medium heat until they’re tender and the mushrooms have released their moisture, five to seven minutes.

Editor’s Tip: Don’t rush the cooking process—properly sauteed mushrooms will add depth and richness to this wild rice casserole.

Step 3: Combine the ingredients

In a large bowl, combine the mushroom mixture, soaked wild rice, uncooked long grain rice, almonds, chicken broth and heavy cream. Season with salt and pepper to taste.

Step 4: Bake the casserole

Transfer the mixture to a greased 2-1/2 quart baking dish. Cover it with aluminum foil and bake for 75 minutes.

Step 5: Add the cheese

Uncover the casserole and sprinkle with grated Parmesan cheese. Bake for an additional 10 minutes, or until the rice is tender and the cheese is melted and lightly golden.

Editor’s Tip: For a golden brown crust, broil the wild rice casserole for the last two minutes. Make sure to watch it closely to avoid burning.

Wild Rice Casserole Variations

  • Make it vegetarian: Use vegetable broth instead of chicken broth for a vegetarian version of this wild rice casserole recipe.
  • Add protein: Stir in cooked shredded chicken, turkey or ham to make the wild rice casserole heartier.
  • Include more vegetables: Add diced bell peppers, celery, carrots or spinach to the casserole for extra color and nutrients.
  • Add more nuts: Chopped pecans, walnuts and pine nuts can all be added for extra crunch. For even more flavor, lightly toast the nuts before adding them to the casserole.
  • Herb it up: Stir in fresh herbs like chopped thyme, rosemary or sage for an aromatic twist to your casserole.
  • Top with more cheese: For an even cheesier crust, mix in sharp cheddar or mozzarella cheese with the Parmesan before adding it to the top of the casserole.
