Before you start

Start by gathering all ingredients and preheating your oven. Ensure the baking dish is clean and dry. Slice the white mushrooms into consistent, thin pieces using a sharp chef knife to ensure they cook at the same rate as the rice.

Prepare the creamy mushroom broth in a pitcher for easy pouring. Clear your workspace to allow for the assembly of the layers, ensuring the baking dish is placed on a stable, heat-resistant surface before you begin adding the ingredients.

Ingredients at a glance (4)
  • 1 cup wild rice blend
  • 1 lb white mushrooms, sliced
  • 2 1/2 cups creamy mushroom broth
  • 1 cup shredded Gruyère cheese

Instructions

Layering the ingredients

  1. Assemble the base
    Preheat the oven to 375°F (190°C). In a large rectangular ceramic baking dish, spread the dry wild rice blend evenly across the bottom. Arrange the sliced white mushrooms in a uniform layer directly over the dry rice.
    Look for The rice should be completely covered by the mushroom slices.
    Tip Ensure the mushrooms are sliced to a consistent thickness for even cooking throughout the baking process.

The rice should be evenly distributed across the base of the dish, with the mushrooms forming a dense, uniform layer on top. Ensure the mushrooms are not overlapping too heavily in one area to maintain consistent cooking throughout the entire pan. This stage sets the foundation for the final texture, so take a moment to ensure everything is level and ready for the liquid.

Baking with broth

  1. Add liquid and bake
    Pour the creamy mushroom broth over the rice and mushrooms in the baking dish. Cover the dish tightly with foil and place it in the preheated oven. Bake for 40 minutes, then remove the foil carefully to avoid steam burns.
    Look for The liquid should be bubbling around the edges after removing the foil.
    Tip Using a glass pitcher helps to distribute the broth evenly across the entire surface of the dish.

After the initial baking period, the rice should have absorbed the broth and become tender. When you remove the foil, the mixture should smell aromatic and earthy. The mushrooms should look plump and soft.

If the rice still seems too firm or dry, check the edges of the dish for liquid; there should be a small amount of creamy broth visible to ensure the dish remains moist.

Melting the cheese

  1. Finish with cheese
    Sprinkle the shredded Gruyère cheese over the top of the rice and mushroom mixture. Return the dish to the oven, uncovered, and bake for an additional 5 minutes until the cheese is melted and lightly golden. Remove from the oven and let rest for 5 minutes before serving.
    Look for The cheese should be melted and show a slight stretch when lifted with a spoon.
    Tip Letting the dish rest allows the rice to absorb any remaining liquid, resulting in a perfect texture.

Once the cheese is added, the final baking step should result in a beautiful, bubbling surface. The Gruyère should look melted and slightly golden. The entire dish should be hot and fragrant. Before removing from the oven, ensure the liquid has reduced enough to create a cohesive, creamy sauce that binds the rice and mushrooms together into a single, hearty serving.

Common mistakes

A common mistake is failing to seal the baking dish tightly with foil, which allows essential steam to escape and results in unevenly cooked, crunchy rice. Another error is overcrowding the pan with too many mushrooms, which can release excess water and make the dish overly soupy.

Finally, adding the cheese too early can cause it to become rubbery or burnt; always wait until the final few minutes of the cooking process to add the topping for the best flavor and texture results.

How to tell it’s done

The dish is done when the wild rice is tender and has absorbed the majority of the liquid, leaving a creamy, sauce-like consistency at the bottom of the dish. The mushrooms should be soft and fully cooked through.

The Gruyère cheese should be completely melted, bubbling slightly at the edges, and showing a light golden-brown color on the surface. Allow the dish to rest for 5 minutes to let the textures settle before serving to ensure the best possible presentation and mouthfeel.
