Ingredients
Scale
Polenta Base
- 1 cup Polenta
- 4 cups Vegetable Broth (can substitute with chicken broth)
- 1 teaspoon Salt
- 1 teaspoon Black Pepper
Sautéed Mushrooms
- 2 tablespoons Olive Oil
- 1 medium Onion, diced
- 3 cloves Garlic, minced
- 16 ounces Assorted Mushrooms (cremini, shiitake, and button), sliced
- 1 teaspoon Dried Thyme
Cheese Topping
- 1 cup Mozzarella Cheese, shredded
- ½ cup Parmesan Cheese, grated
Garnish
- 1 tablespoon Fresh Parsley, chopped (optional)
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole later.
- Cook Polenta: In a saucepan, bring the vegetable broth to a gentle boil. Whisk in the polenta, then reduce the heat and continue stirring for about 5–7 minutes until the mixture thickens into a creamy consistency.
- Sauté Onions and Garlic: Heat olive oil in a skillet over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes, then add minced garlic and cook for an additional minute to release its aroma.
- Cook Mushrooms: Stir in the sliced mushrooms, dried thyme, salt, and black pepper. Cook the mixture until the mushrooms become tender and release their moisture, about 8–10 minutes.
- Combine Polenta and Mushrooms: Gently fold the thickened polenta into the mushroom mixture until everything is evenly combined and creamy.
- Add Cheese to Mixture: Mix in half of the shredded mozzarella and grated Parmesan cheese, allowing them to melt into the creamy mixture.
- Prepare Baking Dish: Pour the combined polenta and mushroom mixture into a greased 9×13-inch baking dish, spreading it out evenly.
- Add Cheese Topping: Sprinkle the remaining mozzarella and Parmesan cheeses evenly over the top of the casserole.
- Bake: Place the dish in the preheated oven and bake for 20–25 minutes, or until the cheese topping is melted and golden brown.
- Garnish and Serve: Remove from the oven and let cool for a few minutes. Garnish with fresh chopped parsley for added freshness before serving warm.
