In the bustling world of cookbooks, certain titles stand out, not just for their stunning photography or elaborate dishes, but for their profound ability to simplify the culinary process. Lukas Volger, renowned author of bestsellers like Bowl and Veggie Burgers Every Which Way, has graced our kitchens once again with his latest culinary masterpiece: Start Simple. This exceptional book promises to transform everyday cooking into a cherished habit, offering a collection of recipes and invaluable tools designed for accessibility and joy.
The core philosophy of Start Simple is beautifully encapsulated in its subtitle: “Eleven Everyday Ingredients for Countless Weeknight Meals.” This guiding principle immediately captures the imagination, suggesting a world where culinary creativity flourishes even with a limited pantry. Among these foundational ingredients are humble staples like canned and dried beans, versatile tortillas, a crisp head of cabbage, nutrient-dense hearty greens, the robust florets of cauliflower and broccoli, a protein-packed block of tofu, and, to my utter delight, a generous pile of mushrooms.
As I first delved into the pages of Start Simple, I found myself utterly captivated. Each recipe seemed to beckon, promising delicious simplicity. The chapter dedicated to “a pile of mushrooms” was particularly enchanting, a veritable treasure trove of ideas that instantly made my heart sing. I earmarked countless pages, eager to try everything from shiitake lettuce cups to a hearty skillet mushroom strata, and a sophisticated mushroom and radicchio pasta adorned with nutty gremolata. The possibilities felt endless, each more tempting than the last.
However, the first recipe from this inspiring collection that I decided to embark upon was this exquisite Roasted Mushroom Polenta Bake. And I can say with absolute certainty that it was a decision I truly cherish. This dish arrived at the perfect moment, a time of year when the long embrace of winter feels like it’s lingering a little too long, yet the craving for deeply warming and comforting sustenance remains. It’s for those days when the thought of roasting another root vegetable, while delicious, feels momentarily overwhelming (though, rest assured, I will return to them tomorrow!). It’s for when you desire something profoundly satisfying and hearty, but without the commitment of extensive chopping or an entire afternoon spent in the kitchen. In these moments, mushrooms, with their inherently meaty texture and profound earthy flavor, truly shine, carrying the weight of the meal with effortless grace.
Effortless Preparation, Exquisite Flavor
One of the most remarkable aspects of this Roasted Mushroom Polenta Bake is its incredibly minimal preparation. This dish truly comes together in a snap, making it an ideal choice for busy weeknights or whenever you crave maximum flavor with minimal fuss. In fact, you don’t even need to meticulously chop the mushrooms. The beauty lies in their rustic charm; simply tear them into irregular, bite-sized pieces. This simple act not only saves time but also allows the mushrooms to develop varied textures as they roast, some edges crisping more than others. Once torn, these fungi are lovingly tossed with fragrant olive oil and a splash of bright vinegar, seasoned perfectly, and then sent to the oven for a quick roast, typically about 20 minutes, allowing their deep, umami flavors to intensify and their textures to become tender-crisp.
While the mushrooms are undergoing their transformation in the oven, the polenta takes center stage on the stovetop. This creamy, golden base begins to materialize, simmering gently into a velvety concoction. The timing is impeccable: just as the roasted mushrooms emerge, golden and fragrant, they are united with the bubbling polenta. A delicate sprinkling of fresh thyme leaves and a generous grating of Parmigiano Reggiano are added, infusing the dish with herbaceous notes and a rich, salty depth. The entire pan then makes a triumphant return to the oven. During this crucial second bake, the roasted mushrooms deepen in flavor and toast further, their savory essences melding seamlessly into the creamy polenta. The polenta itself undergoes a magical transformation, thickening beautifully and developing irresistibly crisp edges. The dish is perfectly ready when the entire sphere of polenta and mushrooms exhibits a gentle undulation, a soft shimmer that suggests it could, given enough time, simply lift itself out of the pan in one glorious, cohesive entity.
Customization and Serving Suggestions
While this Roasted Mushroom Polenta Bake is undeniably delicious straight from the oven, its inherent simplicity provides a wonderful canvas for customization. I find immense pleasure in drizzling the finished dish with a little extra virgin olive oil, its fruity notes enhancing the earthy mushrooms and creamy polenta. A generous cracking of fresh black pepper over the top adds a delightful aromatic kick and a subtle warmth. But the culinary adventure doesn’t have to end there. Imagine showering it with a handful of toasted walnuts or hazelnuts for an added layer of crunch and nutty flavor. For those seeking an extra boost of protein and richness, a perfectly poached egg, its yolk still runny, or a crispy fried egg placed atop each serving would be an absolute dream. And if you’re looking to sneak in some extra greens, gently sautéed spinach, kale, or Swiss chard could be folded in or layered on top, adding vibrant color and nutritional value. The possibilities are truly boundless with this perfect “simple start,” making it adaptable to whatever ingredients you have on hand or whatever culinary mood strikes you.

The Culinary Journey: A Step-by-Step Visual Guide
Let’s walk through the creation of this delightful Roasted Mushroom Polenta Bake, a true testament to the elegance of simple cooking.
Here’s the play-by-play: Begin by preparing about a pound of fresh mushrooms. These could be cremini, shiitake, oyster, or a mix of your favorites. Toss them generously with two tablespoons of olive oil, two teaspoons of vinegar (white, red, apple cider, or white balsamic all work beautifully), and season them with kosher salt and freshly cracked black pepper. Spread them evenly on a baking sheet and roast for 15 to 20 minutes, or until…
…they achieve a beautiful golden hue and become wonderfully tender, with slightly crisped edges. Their earthy aroma will fill your kitchen.
While the mushrooms are roasting, begin preparing the creamy polenta. Measure out a cup of high-quality polenta, ready to be introduced into the simmering liquid.
Carefully pour the measured polenta into 5 (or for an even creamier result, 6) cups of water in a large, oven-safe skillet and bring it to a gentle simmer, whisking constantly to prevent lumps.
After about 20 minutes of simmering over low heat, the polenta should be beautifully thick and bubbling contentedly. Stir in two tablespoons of olive oil, then season generously with salt and pepper to taste, ensuring a rich, savory foundation.
Next, gather some fresh thyme. Gently chop the aromatic leaves, preparing them to release their herbaceous essence into the dish.
Carefully spread the roasted mushrooms in an even layer over the creamy polenta. Then, generously sprinkle the freshly chopped thyme leaves over the top, adding a layer of fresh, aromatic flavor.
For an extra touch of indulgence, grate some high-quality Parmigiano Reggiano over the entire dish, allowing its salty, nutty notes to melt into the polenta and mushrooms during the final bake.
Return the pan to the oven for another 15 to 20 minutes. This final bake allows the flavors to meld beautifully, the polenta to crisp at the edges, and the parmesan to turn golden and bubbly. The anticipation is part of the pleasure!
Serve this exquisite dish immediately, ensuring its warmth and comforting embrace are fully enjoyed. Offer additional grated parmesan and freshly cracked pepper on the side for those who desire more. A final drizzle of quality olive oil over each serving adds a luxurious finish and enhances the overall flavor profile.

Description
Adapted from Lukas Volger’s Start Simple. This comforting and simple vegetarian dish features earthy roasted mushrooms baked into creamy polenta, finished with savory parmesan.
Recent Updates 1/17/2025: I’ve found that using 6 cups of water instead of 5 cups results in an even creamier final polenta. Additionally, I now maintain a consistent oven temperature of 425ºF throughout the entire baking process for optimal results.
Notes:
- Mushrooms: Feel free to use a mix of your favorite mushrooms. I often combine varieties from Asian markets with pre-sliced “wilds” and creminis (also known as “Baby Bellas”) from the grocery store. I typically use around 1.25 lbs of mushrooms for a heartier bake, so don’t hesitate to use a little extra if you have them on hand.
- Vinegar: Any vinegar works well here. White vinegar, red wine vinegar, apple cider vinegar, or white balsamic (my personal favorite) will all add a lovely bright note.
- Parmigiano Reggiano: The original recipe suggests drizzling with 2 tablespoons of heavy cream before baking, which sounds delightful. If I have cream, I’ll definitely try it next time. However, I often use grated parmesan in its place because I always have it on hand, and the combination of mushrooms, polenta, and parmesan is simply unbeatable.
- Non-Dairy Substitute: For a dairy-free version, simply omit both the cream and the cheese. Lukas Volger suggests drizzling the assembled polenta bake with a bit more olive oil before transferring it to the oven to achieve a similar rich finish.
- Other thoughts: Toasted walnuts or hazelnuts would be a fantastic textural addition. If you’re looking to add protein, a perfectly poached or fried egg on top would be a wonderful complement.
Ingredients
For the mushrooms:
- 1 to 1.25 lbs. mushrooms, any variety or a combination (see notes above)
- 2 tablespoons olive oil
- 2 teaspoons vinegar (see notes above for options)
- Kosher salt (Diamond Crystal brand recommended)
- Freshly cracked black pepper
For the polenta bake:
- 1 cup polenta (fine or medium grind)
- 2 tablespoons olive oil
- All of the roasted mushrooms from above
- 2 teaspoons fresh thyme leaves, finely chopped
- Grated Parmigiano Reggiano, to taste (or heavy cream, see notes above)
Instructions
- Preheat your oven to 425ºF (220ºC).
- Prepare the mushrooms: Trim off and discard any tough stems, especially from varieties like shiitakes. Cut or tear the mushroom caps into rough 1-inch pieces. Arrange them in a single, even layer on a baking sheet (lining with parchment paper will make cleanup much easier). Drizzle with the 2 tablespoons olive oil and 2 teaspoons vinegar. Season generously with kosher salt and freshly cracked black pepper to your taste. For a pound of mushrooms, I typically use about a teaspoon of Diamond Crystal kosher salt (use half if you’re using Morton’s brand). Toss everything together to ensure the mushrooms are well coated, then spread them back into an even layer. Transfer the baking sheet to the preheated oven and roast for approximately 20 minutes, or until the mushrooms are tender and just starting to develop a beautiful golden-brown color at their edges. Remove the pan from the oven and set aside.
- While the mushrooms are roasting, prepare the polenta: In a large, wide, oven-safe skillet (one that can go from stovetop to oven), bring 6 cups of water to a gentle simmer over medium-high heat. While whisking continuously and vigorously, slowly pour the polenta into the simmering water in a steady, thin stream. Continue whisking for a couple of minutes until the polenta is fully incorporated and no lumps remain. Reduce the heat to the lowest setting, ensuring a very gentle simmer. Stir in 1 teaspoon of kosher salt (I often use 2 teaspoons of Diamond Crystal kosher salt, as I enjoy a saltier flavor, but adjust to your preference). Let the polenta simmer for 15 to 20 minutes, stirring occasionally, until it has thickened considerably and the grains are tender. Stir in the 2 tablespoons of olive oil. Carefully taste the polenta (allow it to cool slightly on the spoon before tasting) and adjust seasoning with more salt and pepper as needed. A small sprinkling of flaky sea salt at this stage is also lovely.
- Assemble the bake: Once the polenta is cooked, remove the skillet from the heat. Carefully spread the roasted mushrooms in an even layer over the surface of the creamy polenta. Sprinkle the freshly chopped thyme leaves evenly over the mushrooms. Finish with a generous grinding of fresh black pepper to taste.
- Final Bake and Serve: Transfer the skillet back to the preheated oven and bake for an additional 15 to 20 minutes. The polenta should be bubbling gently around the edges, and the mushrooms should be nicely browned and integrated. If desired, shave or grate more fresh Parmigiano Reggiano over the top during the last few minutes of baking, allowing it to melt into a golden crust. Serve immediately, passing extra salt, pepper, and additional grated parmesan at the table for guests to customize their bowls. A final drizzle of good quality extra virgin olive oil over your individual serving is highly recommended to enhance the flavors.
