Brief Overview:
What makes this casserole stand out is the perfect combination of cheeses, mushrooms, and herbs. The cheddar provides a sharp, creamy base, while Parmesan adds a touch of savory depth.

Additionally, you can adapt it to fit any meal by serving it as a side or main dish, adding to its appeal.
Ingredients Breakdown
Mushrooms:
Button mushrooms are the star of this casserole due to their mild flavor and easy availability. Their firm texture holds up well during baking, providing the perfect base for absorbing the rich flavors of the cheese and seasonings. For variations, you could also use cremini mushrooms for a more robust taste or portobello mushrooms for a meatier texture.
Cheeses:
The blend of cheddar and Parmesan offers a balance of sharpness and creaminess. Cheddar cheese melts beautifully, giving the casserole a rich, cheesy layer, while Parmesan adds a savory, nutty flavor. The two cheeses complement each other perfectly, ensuring that every bite is both flavorful and indulgent.
Seasonings:
Garlic powder, thyme, salt, and pepper form a simple yet effective flavor base. Garlic adds a savory punch, thyme lends a subtle herbal note, and salt and pepper enhance the natural taste of the mushrooms. For an extra layer of complexity, consider adding Italian seasoning or a pinch of paprika.
Cream and Butter:
Heavy cream adds a luxurious richness, creating a creamy sauce that binds the casserole together. The melted butter, mixed with optional breadcrumbs, brings a golden, crispy topping, adding both flavor and texture to each bite.
Breadcrumbs (Optional):
Breadcrumbs are an optional topping that adds crunch to the casserole. If you’re looking to keep the dish gluten-free, you can omit the breadcrumbs or use a gluten-free version. Alternatively, crushed nuts or seeds could serve as a crunchy topping to keep the texture intact.
Step-by-Step Instructions
Preheating the Oven:
Begin by preheating your oven to 375°F (190°C). Preheating is crucial for ensuring the casserole cooks evenly, allowing the cheese to melt smoothly and the mushrooms to cook through while maintaining their texture.
Preparing the Mushrooms:
Start by slicing your button mushrooms evenly to ensure they cook at the same rate. In a mixing bowl, toss the mushrooms with olive oil, garlic powder, thyme, salt, and pepper. The olive oil helps the mushrooms roast evenly, while the seasonings infuse them with flavor. Tossing the mushrooms ensures that every slice is well-coated for maximum taste.
Layering in the Baking Dish:
Once the mushrooms are seasoned, spread them evenly in a lightly greased 9×13-inch baking dish. This ensures that the mushrooms cook in a single layer, allowing for even baking. Proper layering prevents overcrowding, which can lead to soggy mushrooms.
Adding Cheeses and Cream:
Next, sprinkle the shredded cheddar and grated Parmesan over the mushrooms, ensuring even coverage across the dish. The cheeses will melt into the mushrooms, creating a creamy, cheesy topping. Afterward, pour the heavy cream evenly over the dish, which will bind the casserole and add richness.
Breadcrumb Mixture:
For a crunchy topping, mix the melted butter with breadcrumbs in a small bowl. This will create a crispy, golden crust that contrasts beautifully with the creamy filling. If you prefer a gluten-free version, omit the breadcrumbs or substitute with a gluten-free option or crushed nuts. Sprinkle the breadcrumb mixture evenly over the casserole.
Baking and Broiling:
Bake the casserole in the preheated oven for 25-30 minutes, until the top is golden brown and the sauce is bubbling. For an extra crispy topping, broil the casserole for an additional 2-3 minutes. Watch carefully during broiling to avoid burning the breadcrumbs.
Resting the Casserole:
Once the casserole is out of the oven, let it rest for a few minutes before serving. This allows the sauce to thicken slightly and the flavors to meld together, ensuring a perfectly cohesive dish when sliced and served.
Tips and Variations
Cheese Substitutions:
If you want to change up the flavor, try using other cheeses like mozzarella for a stretchy, mild flavor, Swiss for a nutty twist, or Gouda for a smokier touch. These substitutions can alter the taste profile of the dish while keeping it cheesy and indulgent.
Adding Protein:
To make this casserole more substantial as a main dish, consider adding cooked chicken, ham, or crumbled bacon. These proteins pair wonderfully with the mushrooms and cheeses, turning the casserole into a filling meal that requires no additional sides.
Vegetable Add-Ins:
If you’re looking to boost the vegetable content, try adding spinach, onions, or bell peppers. Spinach will wilt beautifully into the dish, while onions and bell peppers will bring added sweetness and texture. You can sauté these vegetables beforehand to reduce moisture and intensify their flavors.
Gluten-Free or Low-Carb Variations:
For those avoiding gluten, simply omit the breadcrumbs or replace them with a gluten-free version. If you’re following a low-carb diet, you can skip the breadcrumbs altogether or replace them with crushed nuts or seeds for added crunch without the carbs.
Serving Suggestions:
This baked cheesy mushrooms casserole pairs well with a variety of side dishes. Serve it over a bed of rice or alongside pasta for a heartier meal. It also works as a flavorful side dish for meats like grilled steak, roasted chicken, or pork chops. For a lighter option, serve it with a simple side salad or roasted vegetables.
Nutritional Information
Calories and Fat Content:
This baked cheesy mushrooms casserole is rich in calories due to the cheese and heavy cream, with a typical serving containing around 300-400 calories. The heavy cream and cheddar cheese contribute to a higher fat content, making the dish indulgent but calorie-dense. For a lighter version, consider using light cream or half-and-half instead of heavy cream and reducing the amount of cheddar. Skipping the breadcrumb topping or using a lighter cheese such as part-skim mozzarella can also reduce the fat content.
Protein and Carbs:
Mushrooms and cheese provide a good source of protein, with the cheese contributing most of the protein content. Each serving can offer around 10-15 grams of protein, making it a relatively protein-rich dish for vegetarians. The carbohydrate content depends largely on whether you include the breadcrumb topping; without breadcrumbs, this dish is low in carbs, making it suitable for low-carb or keto diets.
Dietary Considerations:
This recipe is naturally gluten-free if you omit the breadcrumbs or use a gluten-free alternative. It’s also suitable for vegetarians, but it can easily be adapted for those on keto diets by reducing or omitting the breadcrumbs and adding more protein like bacon or chicken. For lactose-intolerant individuals, swap the cream and cheese for dairy-free alternatives like almond milk or vegan cheese.
Common Mistakes to Avoid
Soggy Mushrooms:
One common mistake is overcrowding the baking dish, which prevents the mushrooms from cooking evenly and causes them to release excess moisture, making the dish soggy. To avoid this, ensure the mushrooms are spread in an even, single layer in the dish, allowing them to cook properly and retain a firm texture.
Overbaking:
Overbaking can lead to a dry, overcooked casserole. The cheese can become hard, and the mushrooms can lose their tender texture. To avoid this, stick to the recommended baking time (25-30 minutes) and check the casserole for signs of doneness. The cheese should be golden and bubbly, but not burnt, and the mushrooms should be tender but not mushy.
Inconsistent Breadcrumb Topping:
If using a breadcrumb topping, achieving the right texture can be tricky. An uneven mixture can result in some areas being too soggy or burnt. To avoid this, mix the melted butter evenly with the breadcrumbs before sprinkling, and consider broiling for the last 2-3 minutes to achieve a crisp, golden finish without burning.
FAQs
Can I Use Other Types of Mushrooms?
Yes, you can substitute button mushrooms with alternatives like shiitake or portobello mushrooms. Shiitake mushrooms have a more intense, umami flavor, while portobello mushrooms add a meaty texture, making the dish heartier. Just be mindful of cooking times, as larger mushrooms may require a bit more time to cook through.
Can I Make This Dish Ahead of Time?
Absolutely! You can prepare the casserole ahead of time by assembling it up to the baking step, then covering it and refrigerating it for up to 24 hours. When you’re ready to bake, allow it to come to room temperature and follow the baking instructions. This makes it perfect for meal planning or entertaining.
What’s the Best Way to Store Leftovers?
Leftovers can be stored in an airtight container in the refrigerator for 3-4 days. When reheating, it’s best to use the oven to retain the crispy topping and prevent the casserole from becoming soggy. Reheat at 350°F for 10-15 minutes, or until warmed through.
Can I Freeze This Casserole?
Yes, you can freeze this casserole, although the texture of the mushrooms may change slightly after freezing. Assemble the casserole but hold off on the breadcrumb topping. Freeze it tightly covered, and when ready to bake, thaw it in the refrigerator, add the breadcrumb topping, and bake as usual.
Is It Possible to Make This Dish Dairy-Free?
Yes, you can make a dairy-free version by swapping out the heavy cream for a plant-based alternative like almond or coconut milk. Use vegan cheese to replace the cheddar and Parmesan. Just note that the flavor and texture may differ slightly, but it will still be a delicious alternative for those avoiding dairy.
