Ingredients for Vegetarian Garlic Mushroom Rice Bake
- 2 tablespoons olive oil
- 4 tablespoons unsalted butter (divided)
- 1 large yellow onion, finely chopped
- 6 cloves garlic, minced
- 24 ounces cremini mushrooms, cleaned and sliced
- 1½ cups Arborio rice (uncooked)
- ½ cup dry white wine (optional)
- 4½ cups warmed vegetable broth
- 1 tablespoon fresh thyme (leaves removed from stems)
- ¼ cup fresh parsley, chopped (plus more for garnish)
- 1½ teaspoons salt (or to taste)
- 1 teaspoon freshly ground black pepper
- 1 cup Gruyère cheese, shredded
- ½ cup Parmesan cheese, grated
Preparing the Vegetarian Garlic Mushroom Rice Bake
Preheat the Oven
Start by preheating your oven to 400°F (200°C) and positioning 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 over medium-high heat, add the olive oil and 2 tablespoons of the butter. Once melted and foaming, add the chopped onion and sauté for 5-7 minutes until translucent. Then, add the minced garlic and cook for 1 more minute, allowing the aroma to bloom.
Cook the Mushrooms
Now, add the sliced mushrooms to the skillet and stir to coat them with the aromatic mixture. Let them cook undisturbed for 4-5 minutes, then continue cooking (stirring occasionally) for another 10-12 minutes until their liquid has evaporated and the mushrooms are nicely browned and caramelized.
Toast the Rice
Push the mushrooms to the sides of the skillet, and add the remaining 2 tablespoons of butter to the center. Once melted, add the Arborio rice. Stir continuously for about 2 minutes until each grain is coated in butter and the edges appear slightly translucent.
Deglaze the Pan
If using wine, pour it in now and stir constantly, scraping up any browned bits from the bottom of the pan, until the wine has mostly evaporated.
Combine and Simmer
Stir together the toasted rice and cooked mushrooms. Pour in the warmed vegetable broth, add the fresh thyme, chopped parsley, salt, and black pepper. Stir until well combined and bring the mixture to a gentle simmer on the stovetop.
First Bake
Stir in half of the shredded Gruyère and half of the grated Parmesan. Immediately cover the skillet with a tight-fitting lid (or transfer the mixture to the prepared baking dish and cover with foil). Bake for 25-30 minutes until the rice has absorbed most of the liquid.
Create the Cheesy Crust
Remove the dish from the oven, remove 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 an additional 10-15 minutes until the cheese is melted, bubbling, and the top is golden brown. Remove from the oven and let the Vegetarian Garlic Mushroom Rice Bake rest for at least 10 minutes. Garnish generously with fresh parsley before serving.
Serve this comforting and flavorful rice bake as a main course or a delightful side dish. Enjoy the perfect harmony of creamy, cheesy goodness and the earthy, savory notes of the mushrooms and garlic.

FAQs about Vegetarian Garlic Mushroom Rice Bake
Can I use brown rice instead of Arborio rice in this recipe?
While Arborio rice is ideal for achieving the creamy texture characteristic of a rice bake, you can use brown rice as a healthier alternative. However, keep in mind that brown rice requires a longer cooking time and more liquid. You’ll need to adjust the total cooking time and possibly add more vegetable broth to ensure the rice cooks properly. The final texture will be different, as brown rice will be chewier and less creamy than Arborio, but it can still be a delicious option!
How can I adjust the recipe for higher protein content without adding meat?
To increase the protein content of your Vegetarian Garlic Mushroom Rice Bake without using meat, consider adding cooked lentils, chickpeas, or quinoa. These ingredients blend well with the dish and boost its nutritional profile. You can also incorporate a variety of beans or even top the bake with a sprinkle of nutritional yeast for added protein and a cheesy flavor. Just be mindful of the moisture content; you may need to slightly reduce the broth if you add more moist ingredients.
What kitchen tools do I need to prepare this dish efficiently?
To prepare the Vegetarian Garlic Mushroom Rice Bake, you’ll need a few essential kitchen tools: a large skillet or sauté pan for cooking the aromatics and mushrooms, a medium saucepan for simmering the vegetable broth and rice, and a baking dish for the final bake. Additionally, having a wooden spoon for stirring, measuring cups, and a sharp knife for chopping the vegetables will make the process smoother. An oven mitt will also come in handy when handling the hot baking dish.
Can I modify the recipe to make it spicier, and if so, how?
Absolutely! If you want to add some spice to your Vegetarian Garlic Mushroom Rice Bake, consider incorporating ingredients like red pepper flakes or diced fresh chili peppers when sautéing the onions and garlic. You could also add a dash of hot sauce or a sprinkle of cayenne pepper to the broth during cooking. For a different flavor profile, try using spicy cheese varieties, such as pepper jack, instead of the traditional Gruyère or Parmesan. Just adjust the amount to suit your heat preference!
