Ingredients
Makes 6 servings
For the Casserole
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 1 large yellow onion, finely chopped
- 2 cloves garlic, minced
- 2 lbs (about 8 cups) mixed mushrooms (cremini, button, shiitake), sliced
- 1/2 tsp dried thyme
- 1/4 cup all-purpose flour
- 2 cups whole milk, warmed
- 1/2 cup heavy cream
- 1/2 cup vegetable broth
- 1 tsp Dijon mustard
- 1/2 tsp salt, or to taste
- 1/4 tsp black pepper, or to taste
- 1 cup shredded sharp cheddar cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 2 tbsp fresh parsley, chopped (for garnish)
For the Topping
- 1/2 cup panko breadcrumbs
- 2 tbsp grated Parmesan cheese
- 1 tbsp melted butter
Step-by-Step Instructions
-
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the delicious casserole from sticking.
-
Step 2: Sauté the Aromatics
In a large, deep skillet or Dutch oven, melt 2 tablespoons of butter with 1 tablespoon of olive oil over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant.
Small tip: Don’t let the garlic burn; it can turn bitter quickly.
-
Step 3: Cook the Mushrooms
Add the sliced mushrooms to the skillet. Cook, stirring occasionally, until the mushrooms release their liquid and then brown nicely, about 8-10 minutes. Stir in the dried thyme during the last few minutes of cooking. This step builds deep flavor.
Small tip: Cook mushrooms in batches if your pan is too crowded to ensure they brown instead of steam.
-
Step 4: Make the Creamy Sauce Base
Sprinkle the 1/4 cup of all-purpose flour over the cooked mushrooms and stir well. Cook for 1 minute, allowing the flour to absorb the pan juices and toast slightly. This is creating a roux that will thicken your sauce.
-
Step 5: Whisk in Liquids and Season
Gradually whisk in the warm milk, heavy cream, and vegetable broth. Continue whisking until the sauce thickens and becomes smooth, about 3-5 minutes. Stir in the Dijon mustard, salt, and black pepper. Taste and adjust seasonings as needed.
-
Step 6: Add the Cheese
Remove the skillet from the heat. Stir in the shredded sharp cheddar cheese, shredded mozzarella cheese, and 1/2 cup of grated Parmesan cheese until melted and fully incorporated into the sauce. The sauce will become wonderfully rich and cheesy.
-
Step 7: Assemble the Casserole
Pour the cheesy mushroom mixture into your prepared 9×13 inch baking dish, spreading it evenly. This is the heart of your casserole, ready for its golden topping.
-
Step 8: Prepare the Topping
In a small bowl, combine the panko breadcrumbs, 2 tablespoons of grated Parmesan cheese, and 1 tablespoon of melted butter. Mix until the breadcrumbs are evenly coated. This mixture will create a delightful crispy crust.
-
Step 9: Bake to Golden Perfection
Sprinkle the breadcrumb topping evenly over the mushroom mixture in the baking dish. Bake for 25-30 minutes, or until the casserole is bubbly around the edges and the topping is golden brown and crispy. Let it rest for a few minutes before serving.
-
Step 10: Garnish and Serve
Garnish with fresh chopped parsley just before serving. This adds a pop of color and freshness. Serve warm and enjoy your homemade comfort food!
Tips & Variations
- Gluten-Free Option: Simply substitute the all-purpose flour with a gluten-free all-purpose flour blend or cornstarch (use 2 tbsp cornstarch mixed with 2 tbsp cold water, then add to the sauce). Ensure your vegetable broth is also gluten-free.
- Vegetarian/Vegan Option: This recipe is already vegetarian! For a vegan version, use plant-based butter, unsweetened plant milk (like oat or soy), vegan heavy cream, and your favorite dairy-free shredded cheeses. Nutritional yeast can also add a cheesy flavor.
- Add More Vegetables or Protein: Feel free to stir in cooked chicken, crumbled sausage, or even white beans for extra protein. For more veggies, add a cup of spinach, kale, or roasted bell peppers along with the mushrooms.
- Spicy Version: For a kick, add 1/4 teaspoon of red pepper flakes to the skillet with the garlic, or a dash of hot sauce to the sauce mixture. A pinch of cayenne pepper also works wonders.
- Flavor Boost: For an extra layer of umami, add a tablespoon of white wine or dry sherry to the pan after the mushrooms have browned, letting it cook down before adding the flour.
