* 1 medium onion, chopped
* 2 cloves garlic, minced
* 4 tablespoons butter
* 4 tablespoons all-purpose flour
* 3 cups milk
* 1/2 cup heavy cream
* 1 cup grated Gruyere cheese
* 1/2 cup grated Parmesan cheese
* 1/4 cup chopped fresh parsley
* Salt and black pepper to taste
* Optional: Breadcrumbs for topping

Ingredient Breakdown and Substitutions

* **Asparagus:** Fresh asparagus is ideal, but you can use frozen asparagus in a pinch. Just make sure to thaw and drain it well before using.
* **Mushrooms:** A mix of different mushrooms adds depth of flavor, but you can use any type of mushroom you prefer. Cremini mushrooms are a great all-purpose option.
* **Cheese:** Gruyere cheese provides a nutty, slightly sweet flavor that complements the other ingredients perfectly. You can substitute it with Swiss cheese or Fontina cheese if needed. Parmesan cheese adds a salty, savory element.
* **Milk:** Whole milk will result in the creamiest sauce, but you can use 2% milk if you prefer. Avoid using skim milk, as it may not thicken properly.

## Step-by-Step Instructions

Now that we have all our ingredients and equipment ready, let’s get started! Follow these detailed instructions to create the perfect asparagus and mushroom casserole.

Step 1: Prepare the Vegetables

1. Wash the asparagus and pat it dry. Trim off the tough ends and cut the spears into 1-inch pieces.
2. Clean the mushrooms with a damp cloth or brush. Slice the mushrooms into even pieces. If you’re using different types of mushrooms, keep them separate for now.
3. Peel and chop the onion into small pieces.
4. Mince the garlic cloves.
5. Chop the fresh parsley.

Step 2: Sauté the Vegetables

1. Heat 2 tablespoons of butter in a large skillet or sauté pan over medium heat.
2. Add the chopped onion and sauté until softened and translucent, about 5-7 minutes.
3. Add the minced garlic and cook for another minute until fragrant.
4. Add the sliced mushrooms to the skillet and cook until they release their moisture and become tender, about 8-10 minutes. Stir occasionally to ensure even cooking.
5. Add the asparagus pieces to the skillet and cook for another 5-7 minutes, until they are tender-crisp. Be careful not to overcook the asparagus, as it will become mushy.
6. Season the vegetables with salt and black pepper to taste. Remove the skillet from the heat and set aside.

Step 3: Make the Cream Sauce

1. In a separate saucepan, melt the remaining 2 tablespoons of butter over medium heat.
2. Whisk in the all-purpose flour and cook for 1-2 minutes, stirring constantly. This will create a roux, which will help thicken the sauce.
3. Gradually whisk in the milk, making sure to break up any lumps. Continue whisking until the mixture is smooth.
4. Bring the sauce to a simmer, stirring constantly, and cook until it thickens slightly, about 5-7 minutes.
5. Remove the saucepan from the heat and stir in the heavy cream, Gruyere cheese, and half of the Parmesan cheese. Continue stirring until the cheese is melted and the sauce is smooth and creamy.
6. Season the sauce with salt and black pepper to taste.

Step 4: Assemble the Casserole

1. Preheat your oven to 375°F (190°C).
2. Grease a 9×13 inch baking dish with butter or cooking spray.
3. Pour the sautéed vegetables into the prepared baking dish, spreading them evenly over the bottom.
4. Pour the creamy cheese sauce over the vegetables, making sure to coat them evenly.
5. Sprinkle the remaining Parmesan cheese over the top of the casserole.
6. If desired, sprinkle breadcrumbs over the top for a crispy topping.

Step 5: Bake the Casserole

1. Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the casserole is bubbly and the top is golden brown.
2. Remove the casserole from the oven and let it cool for a few minutes before serving.
3. Garnish with fresh parsley before serving.
