Step‑by‑Step Instructions for Baked Cheesy Mushrooms Casserole

Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While it warms up, greasing a 9×13-inch baking dish creates a non-stick surface for your Baked Cheesy Mushrooms Casserole. A light coat of olive oil or butter will ensure that the cheesy goodness doesn’t get stuck as it bakes, making for easy serving later on.

Step 2: Season the Mushrooms
In a large bowl, combine sliced button mushrooms with olive oil, garlic powder, dried thyme, salt, and black pepper. Toss the mushroom mixture until each piece is well-coated in the flavorful seasoning. This step enhances the earthy richness of the mushrooms, ensuring every bite bursts with flavor and prepares them for an inviting casserole.

Step 3: Layer the Mushrooms
Transfer the seasoned mushroom mixture evenly into your prepared baking dish, spreading it out to create a uniform layer. This ensures that every corner bakes perfectly, soaking up all the creamy goodness that will soon follow. The sight of this earthy mound will have your kitchen smelling wonderful!

Step 4: Add the Cheeses
Generously sprinkle shredded cheddar and grated Parmesan cheese over the mushrooms, creating a hearty cheesy layer. The blend of sharpness from the cheddar and nutty hints from the Parmesan will meld beautifully as it bakes, contributing to the signature creamy sauce of your Baked Cheesy Mushrooms Casserole.

Step 5: Pour on the Cream
Evenly pour heavy cream over the entire dish, allowing it to seep into every layer. This crucial step binds the ingredients together, creating that rich and velvety texture that makes this casserole so comforting. You’ll know it’s ready when you see the cream gently bubbling around the edges.

Step 6: Prepare the Topping
In a separate bowl, mix melted butter with breadcrumbs until they are well-coated. This buttery mixture will create a delightful crunch on top of your casserole. Using a spoon, sprinkle the breadcrumb topping evenly over the creamy mushroom and cheese layers, ensuring every part of the dish gets the crispy treatment.

Step 7: Bake to Perfection
Place the casserole in your preheated oven and bake for 25-30 minutes. Keep an eye out for a beautifully golden top and bubbling sauce, signaling that the casserole is done. The combination of textures will create a delicious visual feast that makes the Baked Cheesy Mushrooms Casserole irresistible.

Step 8: Broil for Extra Crunch
If you crave an extra crispy topping, switch your oven to broil for the last 2-3 minutes of baking. Watch closely as the breadcrumbs turn a rich golden brown, adding an irresistible crunch that contrasts beautifully with the creamy mushroom base. Just remember, it can brown quickly!

Step 9: Rest and Garnish
Once baked to perfection, remove the casserole from the oven and let it rest for a few minutes to set. This resting time allows the creamy sauce to thicken. Before serving, garnish with freshly chopped parsley for a pop of color and freshness. Your Baked Cheesy Mushroom Casserole is now ready to be enjoyed!
