How to Make Cheesy Mushroom Casserole Creating this cheesy mushroom casserole is a breeze. With just a few simple steps, you’ll have a dish that’s not only delicious but also comforting. Let’s get started! Step 1: Preheat the Oven First things first, preheat your oven to 350°F (175°C). This ensures that your casserole bakes evenly and comes out perfectly golden. Step 2: Sauté the Onions In a large skillet, heat two tablespoons of olive oil over medium heat. Add the chopped onion and sauté for about three minutes until it turns translucent. This step builds the foundation of flavor for your casserole. Step 3: Cook the Mushrooms and Garlic Next, toss in the sliced mushrooms and minced garlic. Cook for an additional five to seven minutes until the mushrooms are tender and any liquid has evaporated. The aroma will be heavenly, trust me! Step 4: Season the Mixture Now, stir in one teaspoon of dried thyme, one teaspoon of salt, and half a teaspoon of black pepper. Mix well and remove the skillet from heat. Let it cool slightly while you prepare the next steps. Step 5: Combine Rice and Cheese In a large bowl, combine one cup of cooked rice, one cup of shredded cheddar cheese, one cup of sour cream, and half a cup of milk. Mix everything together until it’s well combined. This creamy mixture is what makes the casserole so indulgent. Step 6: Mix Everything Together Add the cooled mushroom mixture to the rice and cheese blend. Stir until everything is fully combined. You want every bite to be packed with flavor! Step 7: Prepare for Baking Transfer the mixture to a greased 9×13 inch baking dish. In a small bowl, mix half a cup of breadcrumbs with a quarter cup of grated Parmesan cheese. Sprinkle this crunchy topping evenly over the casserole for that perfect finish. Step 8: Bake the Casserole Place the baking dish in your preheated oven. Bake for 25 to 30 minutes, or until the top is golden brown and bubbly. The anticipation will be worth it!
