Ingredients
Scale
Polenta Base
- 1 cup Polenta
- 4 cups Vegetable Broth
- 1 teaspoon Salt
Sautéed Mushrooms
- 2 tablespoons Olive Oil
- 1 medium Onion, diced
- 3 cloves Garlic, minced
- 16 ounces Assorted Mushrooms (cremini, shiitake, button), sliced
- 1 teaspoon Dried Thyme
- 1 teaspoon Black Pepper
Cheeses and Garnish
- 1 cup Mozzarella Cheese, shredded
- ½ cup Parmesan Cheese, grated
- 1 tablespoon Fresh Parsley (optional)
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
- Cook Polenta: In a saucepan, bring the vegetable broth to a gentle boil. Whisk in the polenta, then reduce heat to low. Stir continuously for about 5–7 minutes until the polenta thickens to a creamy consistency.
- Sauté Aromatics: Heat olive oil in a skillet over medium heat. Add the diced onion and sauté until translucent, about 3–4 minutes. Add minced garlic and cook for an additional minute to release its aroma.
- Cook Mushrooms: Add the sliced mushrooms, dried thyme, salt, and black pepper to the skillet. Cook, stirring occasionally, until the mushrooms are tender and have released their moisture, about 8–10 minutes.
- Combine Polenta and Mushrooms: Gently fold the cooked polenta into the mushroom mixture, stirring until well combined and creamy.
- Add Cheese to Mixture: Stir in half of the shredded mozzarella and grated Parmesan cheese into the polenta and mushroom mixture until the cheeses melt and incorporate fully.
- Assemble Casserole: Pour the combined mixture into a greased 9×13-inch baking dish, spreading it evenly.
- Top with Remaining Cheese: Sprinkle the remaining mozzarella and Parmesan evenly over the top of the casserole.
- Bake: Bake in the preheated oven for 20–25 minutes, until the cheese on top is melted and golden brown.
- Garnish and Serve: Allow the casserole to cool for a few minutes before garnishing with fresh parsley. Serve warm and enjoy your comforting mushroom polenta casserole.
Notes
- You can substitute vegetable broth with chicken broth for a richer flavor if not vegetarian.
- For an extra creamy texture, add a tablespoon of butter or cream while stirring polenta.
- Feel free to experiment with mushroom varieties such as portobello or oyster for different textures and flavors.
- The casserole can be prepared a day in advance and baked just before serving.
- Leftovers can be refrigerated and reheated in the oven to maintain crispiness on top.
