Step‑by‑Step Instructions for Mushroom Polenta Casserole Step 1: Prepare the Polenta Begin by bringing water or vegetable broth to a boil in a medium saucepan. Gradually whisk in the polenta, stirring constantly to avoid lumps. Cook for about 10-15 minutes on low heat, continuing to stir until the polenta is thick and creamy, achieving a smooth texture that pulls away from the sides of the pan. Step 2: Sauté the Mushrooms While the polenta is cooking, heat a large skillet over medium heat and add a drizzle of olive oil. Once hot, add the sliced mushrooms, seasoning with salt and pepper. Sauté for 8-10 minutes until the mushrooms are tender and golden brown, releasing their moisture and deepening their flavors, then remove from heat. Step 3: Mix the Ingredients In a large bowl, combine the cooked polenta, sautéed mushrooms, and cheese. Stir in a splash of vegetable broth if you prefer a creamier texture. Mix well until everything is evenly distributed, creating a luscious filling for your Mushroom Polenta Casserole that showcases the earthy flavors of the mushrooms and the richness of the cheese. Step 4: Layer in a Casserole Dish Preheat your oven to 375°F (190°C). Grease a 9×13 inch casserole dish with olive oil or cooking spray. Spread half of the polenta mixture evenly across the bottom of the dish. Layer with extra cheese or sautéed seasonal vegetables if desired, then top with the remaining polenta mixture for a hearty, satisfying layer. Step 5: Bake the Casserole Place the assembled Mushroom Polenta Casserole in the preheated oven and bake for 30-40 minutes. Look for a golden-brown, bubbling top—this indicates the casserole is ready. The delicious aroma will fill your kitchen, signaling that a comforting meal is on its way. Step 6: Cool Slightly & Serve Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes. This resting time allows the flavors to meld and makes it easier to slice.
