Ingredients in Roasted Mushroom Polenta Bake
Polenta – The base of our dish! When baked, it turns into a soft yet slightly firm, creamy delight that holds up beautifully under the mushrooms.
Mushrooms – The real stars here! Roasting brings out their deep, umami flavor, making them extra rich and meaty. Choose a mix like cremini, shiitake, or portobello for variety.
Parmesan Cheese – Because what’s polenta without a little cheesy goodness? This adds a salty, nutty depth of flavor.
Garlic – Roasted garlic takes this dish to the next level, adding an irresistible aroma and taste.
Vegetable Broth – Cooking the polenta in broth (instead of water) gives it a boost of flavor.
Butter – A little butter makes everything better, adding richness and silkiness to the polenta.
Olive Oil – Helps the mushrooms roast to golden perfection.
Fresh Herbs – Think thyme, rosemary, or parsley to bring some freshness and balance to the dish.
Salt and Pepper – The finishing touch to enhance all the flavors.

How to Make Roasted Mushroom Polenta Bake
Preheat Your Oven – Set your oven to 375°F to ensure an even bake. This allows the polenta and mushrooms to cook perfectly together.
Roast the Mushrooms – Toss your mushrooms with olive oil, garlic, salt, and pepper, then spread them on a baking sheet. Roast until they’re golden and fragrant.
Cook the Polenta – In a saucepan, bring vegetable broth to a simmer. Gradually whisk in the polenta, stirring constantly to avoid lumps. Let it cook until thick and creamy.
Add Cheese & Butter – Stir in Parmesan cheese and butter to make the polenta extra creamy and flavorful.
Assemble the Bake – Pour the cooked polenta into a greased baking dish, spreading it evenly. Top with the roasted mushrooms and any pan juices.
Bake to Perfection – Pop it into the oven for 15-20 minutes, just until everything melds together and the top gets slightly golden.
Let it Rest – Once out of the oven, let the dish sit for a few minutes to allow flavors to settle.
Serve & Enjoy – Garnish with fresh herbs and dig in! Whether you serve it as a main dish or a side, this is one for the books.
How to Serve Roasted Mushroom Polenta Bake

As a Standalone Meal – This dish is hearty enough to enjoy on its own—just add a sprinkle of fresh herbs on top.
Additional Tips
Make It Ahead – Cook the polenta and roast the mushrooms a day in advance, then assemble and bake when you’re ready.
Spice It Up – Add red pepper flakes or smoked paprika for extra depth.
Storage Tips – Keep leftovers in an airtight container in the fridge for up to 4 days.
Reheating – Warm it up in the oven at 350°F for the best texture. If microwaving, add a splash of broth to keep it creamy.

Ingredients
For the Mushrooms:
- 1 to 1.25 lbs. mushrooms (any variety or mix)
- 2 tbsp olive oil
- 2 tsp vinegar (white, red, apple cider, or white balsamic)
- 1 tsp kosher salt (Diamond Crystal; use 1/2 tsp if using Morton)
- Freshly cracked black pepper, to taste
For the Polenta Bake:
- 1 cup polenta
- 6 cups water
- 2 tbsp olive oil
- 2 tsp fresh thyme leaves
- Grated Parmigiano Reggiano, to taste (or 2 tbsp heavy cream)
Instructions
- Preheat the Oven: Set your oven to 425°F (220°C).
- Prepare the Mushrooms: Trim off tough stems (if using shiitakes) and cut or tear the mushrooms into 1-inch pieces. Spread them on a parchment-lined baking sheet. Drizzle with olive oil, vinegar, salt, and black pepper, tossing to coat. Roast for 20 minutes until they develop some color.
- Cook the Polenta: In a large oven-safe skillet, bring 6 cups of water to a simmer. While whisking constantly, slowly add the polenta in a steady stream. Continue whisking for 2 minutes to incorporate. Reduce heat to low, add kosher salt, and simmer for 15-20 minutes until thick and tender. Stir in olive oil, adjust seasoning with salt and pepper, and remove from heat.
- Assemble the Bake: Spread the roasted mushrooms evenly over the polenta. Sprinkle with thyme and black pepper.
- Bake: Transfer to the oven and bake for 15-20 minutes, until bubbling and golden.
- Serve: Top with more parmesan or a drizzle of olive oil, if desired. Serve warm with extra salt and pepper on the side.
