Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Polenta: Choose quick-cooking polenta for a smooth texture that cooks up in no time.
Wild Mushrooms: A mix of shiitake and cremini adds depth; just avoid any sketchy-looking ones!
Fresh Thyme: Always opt for fresh herbs; they infuse vibrant flavor compared to dried varieties.
Heavy Cream: For that rich, velvety finish that makes each bite feel indulgent.
Parmesan Cheese: Grate your own for maximum flavor – store-bought pre-grated just doesn’t cut it.
Butter: Unsalted butter works best to control the seasoning in this dish.
Garlic: Fresh garlic cloves bring out the earthy notes of the mushrooms beautifully.
Onion: Sweet onions add a lovely depth when sautéed until golden brown.
Salt and Pepper: Essential for balancing flavors – don’t skip these pantry staples!

How to Make Wild Mushroom & Thyme Polenta Gratin
Prepare Your Baking Dish: Preheat your oven to 375°F (190°C). Grease a rectangular baking dish with butter to prevent sticking and ensure every delicious morsel comes out easily.
Sauté the Vegetables: In a large skillet over medium heat, melt some butter and add diced onions. Cook until they turn golden brown and fragrant—about 5 minutes—then toss in minced garlic and wild mushrooms until softened.
Cook the Polenta: Bring water to a boil in another pot before whisking in polenta gradually. Stir continuously until thickened—this takes about 5-7 minutes—then remove from heat and fold in heavy cream, grated Parmesan cheese, salt, pepper, and fresh thyme.
Combine Layers: In your prepared baking dish, spread half of the polenta mixture evenly across the bottom. Layer half of the sautéed mushroom mixture on top before repeating these layers with remaining ingredients.
Bake Until Golden: Place in preheated oven and bake uncovered for 25-30 minutes or until bubbly and golden brown on top. Allow it to cool slightly before serving – if you can resist!
