How to Make Vegetarian Garlic Mushroom Rice Bake
Ingredients

- 2 tablespoon olive oil
- 2 tablespoon unsalted butter
- 1 medium yellow onion, chopped
- 3 cloves garlic, minced
- 8 ounces cremini mushrooms, sliced
- 1 cup Arborio rice
- 4 cups vegetable broth, warmed
- 1 tablespoon fresh thyme, chopped
- 1/4 cup fresh parsley, chopped
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 cup Gruyère cheese, shredded
- 1/2 cup Parmesan cheese, grated
Directions
Preheat the Oven: Begin by setting your oven to 400°F and position a rack in the middle. If your skillet isn’t oven-safe, prepare a 9×13-inch baking dish.
Sauté the Aromatics: In a large oven-safe skillet or Dutch oven, heat the olive oil and 2 tablespoons of butter over medium heat. Add the chopped onion and sauté until it becomes translucent. Stir in the minced garlic and cook for an additional minute until fragrant.
Cook the Mushrooms: Add the sliced mushrooms to the skillet and let them cook undisturbed for 4-5 minutes. Afterward, continue cooking for another 10-12 minutes, stirring occasionally, until the mushrooms are nicely browned and their liquid has evaporated.
Toast the Rice: Push the mushrooms to the sides of the skillet, add the remaining 2 tablespoons of butter in the center, and allow it to melt. Once melted, add the Arborio rice and stir continuously for about 2 minutes, ensuring that each grain is coated in butter and that the edges appear slightly translucent.
Deglaze the Pan: If you choose to use white wine, pour it in and stir constantly, scraping up any browned bits from the bottom of the pan until the wine has mostly evaporated.
Combine and Simmer: Stir the toasted rice and cooked mushrooms together. Pour in the warmed vegetable broth, then add the fresh thyme, chopped parsley, salt, and black pepper. Stir until well combined and bring the mixture to a gentle simmer.
First Bake: Stir in half of the shredded Gruyère and half of the grated Parmesan. Cover the skillet tightly with a lid (or transfer the mixture to the prepared baking dish and cover with foil) and bake for 25-30 minutes, until the rice has absorbed most of the liquid.
Create the Cheesy Crust: After the first bake, carefully remove the dish from the oven, take off the lid or foil, and sprinkle the remaining Gruyère and Parmesan evenly over the top.
Final Bake and Rest: Return the uncovered dish to the oven and bake for an additional 10-15 minutes, until the cheese is melted, bubbling, and the top is golden brown. Remove from the oven and let the bake rest for at least 10 minutes. Garnish generously with fresh parsley before serving.

Pro Tips for Success with Vegetarian Garlic Mushroom Rice Bake
Mix and Match Mushrooms: Don’t hesitate to use a variety of mushrooms. Shiitake, button, or portobello can add unique flavors and textures to your dish.
Stay Hands-On with the Rice: Stirring the rice while toasting ensures an even cooking process, which helps achieve a creamy texture once baked.
Herb Substitutions: If you don’t have fresh thyme or parsley at hand, dried herbs can be used. However, reduce the quantity by about one-third, as dried herbs are more concentrated in flavor.
Cheese Options: Feel free to substitute Gruyère and Parmesan with your favorite cheeses. Mozzarella, Gouda, or even a vegan cheese can work well if you’re looking for dairy-free options.
Don’t Skip the Resting Time: Allowing the dish to rest post-baking allows the flavors to meld further and makes it easier to serve.
Garnish Generously: Fresh herbs sprinkled on top before serving can brighten the dish. Consider adding a squeeze of lemon for an extra zing!
Flavor Variations for Vegetarian Garlic Mushroom Rice Bake
Spinach and Cheese: Add a couple of handfuls of fresh spinach during the final combine step for added nutrients and a pop of color.
Sun-Dried Tomatoes: Mix in chopped sun-dried tomatoes for a tangy contrast to the rich flavors of the cheese and mushrooms.
Nuts for Crunch: Toss in some toasted pine nuts or sliced almonds before serving for added crunch and depth of flavor.
Spicy Kick: Add a dash of red pepper flakes or a few slices of jalapeño for a peppery kick that complements the mushrooms beautifully.
Lemon Zest Finish: For a fresh finish, grate some lemon zest on top prior to serving. It enhances the earthy flavors dramatically.
