Fontina Polenta with Sautéed Porcini Mushrooms: A Gourmet Italian Autumn Recipe
Autumn in Italy brings a special kind of magic to the kitchen, and nothing captures the essence of the season quite like the arrival of fresh porcini mushrooms. This is the perfect time to explore the rich, earthy flavors of the forest through a classic Italian pairing. Today, we are diving into a recipe that combines comfort and elegance: Fontina Polenta with Sautéed Porcini Mushrooms. This dish is a celebration of texture and taste, bringing together the creamy, cheesy goodness of traditional polenta with the meaty, savory punch of world-class mushrooms.
For many households looking to reduce meat consumption without sacrificing flavor, porcini mushrooms are the ultimate culinary weapon. They provide a deep, “umami” profile that satisfies even the most dedicated meat lovers. Whether you are serving this as a sophisticated side dish or a hearty vegetarian main course, it is bound to become a seasonal favorite in your home.
The Evolution of Polenta: From “Cucina Povera” to Gourmet Delight
Historically, polenta has been known as “cucina povera”—the food of the poor. For centuries, it was a simple, filling staple for rural families in Northern Italy. However, modern Italian cuisine has elevated this humble cornmeal into something truly spectacular. By serving polenta in individual gratin dishes and topping it with high-quality ingredients like Fontina cheese and fresh porcini, you transform a basic meal into a fancy presentation that will undoubtedly impress your guests.
The beauty of polenta lies in its versatility. It acts as a blank canvas, ready to soak up the juices of sautéed vegetables, the richness of melted cheeses, and the aromatic notes of fresh herbs. When paired with the “King of Mushrooms,” the porcini, it creates a harmony of flavors that is both rustic and refined.
A Culinary Journey to Montecreto, Italy
My passion for mushrooms is deeply rooted in my family history. During a visit to my family’s native village of Montecreto, nestled in the mountains of Northern Italy, I experienced firsthand how deeply the porcini culture runs. The local restaurants, such as Ristorante Al Focolare, treat these mushrooms with the utmost respect. From the moment you see the menu displayed outside, your appetite is teased with descriptions of mushroom-based delights.
In these mountain villages, the harvest is a community event. I remember my cousin Enrico showing off a box of freshly harvested porcini, still smelling of the damp forest floor. The chefs there take great pride in their ingredients; it’s not uncommon for a chef to bring a platter of huge, freshly picked porcini to your table, allowing you to select the very mushrooms that will be used in your risotto or antipasti. Whether it’s a simple Crostini ai Funghi or a perfectly crispy plate of fried mushrooms, the quality of fresh Italian porcini is unmatched.

Understanding Your Star Ingredient: What Are Porcini Mushrooms?
If you are new to cooking with porcini, you might wonder what makes them so special. Porcini (Boletus edulis) are brown-capped mushrooms with thick, white stalks. They are highly prized because they are difficult to cultivate and must be foraged in the wild, typically in pine and chestnut forests. Their short growing season in autumn makes them a rare treat.
The flavor profile of a porcini is distinct: it is nutty, earthy, and intense. When cooked, they develop a tender, meaty texture. While fresh porcini are incredible, dried porcini are also a staple in the Italian pantry. They are often rehydrated and used to add depth to broths, stews, and sauces. In fact, the liquid used to soak dried porcini is “liquid gold” and should never be thrown away; it’s packed with concentrated mushroom flavor.

Fontina Polenta with Sautéed Porcini Mushrooms Recipe
This recipe is designed to be straightforward yet flavorful. It uses a combination of dried porcini for depth and fresh baby portobello mushrooms for added bulk and texture.
Ingredients List
For the Mushroom Mixture:
- 4 Tbsp. extra virgin olive oil or butter
- 2 4-ounce packages dried porcini mushrooms (reconstituted, drained, and chopped)
- 1 8-ounce package pre-sliced baby portobello mushrooms
- 1 tsp. minced fresh thyme
- ½ tsp. minced fresh oregano
- 3 garlic cloves, finely chopped
- ½ cup chicken or vegetable broth (optional)
- 1 tsp. salt
- ¼ tsp. black pepper
For the Polenta:
- 2 cups whole milk
- 1 cup chicken or vegetable broth
- 2 to 3 cups instant polenta (adjust based on your preferred thickness)
- 2 to 3 cups shredded Fontina cheese (divided)
- 2 tsp. salt
Preparation Instructions
Step 1: Prepare the Mushrooms
Start by reconstituting the dried porcini mushrooms. Place them in a bowl of hot water for about 20 minutes until they are soft. Once softened, drain them (saving the liquid for other uses if you like) and squeeze out any excess water. Chop the porcini into bite-sized pieces.
In a large skillet, heat the olive oil or butter over high heat. Add both the chopped porcini and the baby portobello mushrooms. Sauté the mushrooms for about 4 minutes until they begin to brown and release their moisture. Add the garlic, thyme, and oregano, and continue to sauté for another minute until fragrant. If the mixture seems too dry, stir in the half-cup of broth. Season with salt and pepper, then set aside.
Step 2: Prepare the Cheesy Polenta
In a large, heavy saucepan, bring the milk and one cup of broth to a boil. Slowly whisk in the instant polenta. Reduce the heat and cook for about 4 minutes, stirring constantly to prevent lumps from forming. Once the polenta is thick and creamy, stir in half of the shredded Fontina cheese and the salt. The cheese should melt completely into the polenta, creating a rich, velvety texture.
Step 3: Assemble and Broil
Preheat your oven to the ‘broil’ setting. Divide the creamy polenta among four individual gratin dishes or one large baking dish. Sprinkle the remaining Fontina cheese over the top of each serving. Place the dishes under the broiler for about 5 minutes, or until the cheese is melted and bubbling with a slightly golden-brown crust.
Step 4: Serving
Carefully remove the dishes from the oven. Top each cheesy polenta base with a generous portion of the sautéed mushroom mixture. Serve immediately while hot.

Expert Tips for Working with Porcini Mushrooms
To get the best results from your porcini, follow these simple guidelines:
- Cleaning: Avoid soaking fresh porcini in water. They are like sponges and will absorb moisture, becoming soggy. Instead, use a damp paper towel or a soft brush to gently wipe away any dirt.
- Selection: When buying fresh porcini, look for firm stalks and brown caps. Avoid mushrooms with black spots or a deep green color under the cap, as these are signs of over-ripeness.
- Storing: Store fresh mushrooms in a loose paper bag in the refrigerator. They are best used within a day or two of purchase. Dried porcini can be kept in an airtight container in a cool, dark place for up to six months.
- Dried vs. Fresh: If you cannot find fresh porcini, do not worry. Dried porcini actually have a more concentrated flavor. Just be sure to buy packages that contain whole slices rather than a lot of crumbs.
Why Fontina Cheese?
Fontina is a classic Italian cheese from the Aosta Valley. It is known for its excellent melting properties and its mild, nutty, and slightly earthy flavor. This makes it the perfect companion for mushrooms. While you could substitute with Gruyère or Provolone, Fontina provides that authentic Northern Italian taste that complements the polenta beautifully.
More Mushroom Inspiration
If this dish leaves you craving more, there are plenty of other ways to enjoy the bounty of the season. A classic Risotto with Porcini Mushrooms is a staple in Venice, known for its creamy consistency and deep aroma. Alternatively, a Mushroom Tart with Three Cheeses (using Fontina, Asiago, and Parmesan) makes for a wonderful appetizer or light lunch.
Cooking with mushrooms is a journey into the heart of Italian comfort food. Whether you are foraging in the woods or shopping at your local specialty market, the combination of Fontina, polenta, and porcini is a timeless tribute to the flavors of autumn. Enjoy the process, and most importantly, enjoy the meal!
