Yield
Serves 6 generous portions
Difficulty Level
Medium – accessible for confident home cooks ready to impress with technique and flavor layering
Ingredients
- 1 cup polenta (coarse cornmeal)
- 4 cups vegetable or chicken broth, heated
- 1 cup whole milk
- 2 tablespoons unsalted butter
- 1 cup sharp aged cheddar cheese, shredded
- 1 cup creamy fontina cheese, shredded
- ½ cup freshly grated Parmesan cheese
- 1 lb mixed mushrooms (shiitake, cremini, and oyster), cleaned and sliced
- 3 cloves garlic, minced
- 1 small shallot, finely chopped
- 2 tablespoons olive oil
- 1 teaspoon fresh thyme leaves
- Salt and freshly ground black pepper, to taste
- Chopped fresh parsley, for garnish
Instructions
- Prepare the polenta: In a heavy-bottomed saucepan, bring the vegetable broth and milk to a gentle boil. Slowly whisk in the polenta to prevent lumps. Reduce heat to low and cook, stirring frequently, until thick and creamy, about 25 minutes.
- Enhance with butter and cheese: Remove from heat, then stir in butter, cheddar, fontina, and Parmesan. Mix until fully melted and smooth. Season with salt and pepper carefully, as cheeses add saltiness.
- Sauté the mushrooms: While polenta cooks, heat olive oil in a large skillet over medium-high heat. Add shallots and garlic, sautéing until fragrant, about 1 minute. Add mushrooms and thyme leaves; cook until mushrooms release moisture and turn golden, 7-8 minutes. Season with salt and pepper.
- Assemble the casserole: Preheat oven to 375°F (190°C). Lightly oil or butter a 9×13-inch baking dish. Spread half the polenta mixture evenly on the bottom, followed by a layer of sautéed mushrooms. Top with the remaining polenta, smoothing the surface with a spatula.
- Add final cheese layer: Sprinkle additional shredded fontina or Parmesan on top to encourage browning and a golden, bubbly crust.
- Bake to perfection: Place casserole in oven and bake for 20-25 minutes, until cheese is melted and lightly golden.
- Rest and garnish: Remove from oven and let sit 5 minutes. Sprinkle with fresh parsley before serving to add a burst of color and freshness.
Tips for Success
- Cheese Blend: The balance of sharp cheddar and creamy fontina melts beautifully, giving both tang and silky texture. You can swap fontina with mozzarella for a different but still creamy experience.
- Mushroom Choice: Combining shiitake, cremini, and oyster mushrooms adds complex earthy notes and distinct textures, but any mix of wild or button mushrooms will work.
- Prevent Polenta Lumpiness: Whisk polenta in gradually and stir constantly during cooking. If it thickens too quickly, a splash of warm broth or milk will help loosen the texture.
- Make-Ahead: Prepare mushrooms and polenta in advance and assemble before baking to save time on the day of serving.
Serving Suggestions
Serve this cozy casserole alongside a crisp arugula salad dressed with lemon vinaigrette to brighten the richness. For added indulgence, drizzle a bit of truffle oil over the top before serving or garnish with sautéed fresh herbs like thyme or rosemary. A glass of medium-bodied red wine or a buttery Chardonnay matches perfectly with the earthy mushroom and creamy cheese layers.
