* 1/2 cup butter
* 1/2 cup all-purpose flour
* 3 cups milk
* 1/2 teaspoon salt
* 1/4 teaspoon black pepper
* 1/4 teaspoon cayenne pepper (optional, for a little kick)
* 1/4 teaspoon nutmeg
* 1 cup shredded Gruyere cheese (or Swiss cheese)
* 1/2 cup shredded Parmesan cheese
* 1/4 cup chopped fresh parsley
* 2 tablespoons dry sherry (optional, but highly recommended)

**For the Topping:**

* 1 cup panko breadcrumbs
* 1/4 cup melted butter
* 1/4 cup grated Parmesan cheese
* 1 tablespoon chopped fresh parsley

## Step-by-Step Instructions

Follow these detailed instructions to create the perfect Shrimp and Crab Casserole:

### Step 1: Prepare the Shrimp

1. **Prepare the Shrimp:** Rinse the shrimp under cold water and pat them dry with paper towels. This removes any excess moisture and helps them brown better.
2. **Cook the Shrimp (Optional):** While you can add raw shrimp to the casserole and let it cook in the sauce, lightly cooking them beforehand ensures they are perfectly cooked and tender. To do this, heat a tablespoon of olive oil or butter in a skillet over medium heat. Add the shrimp and cook for 2-3 minutes per side, or until they turn pink and opaque. Be careful not to overcook them, as they will continue to cook in the casserole.
3. **Cut the Shrimp (Optional):** If you are using large shrimp, you may want to cut them in half or thirds to make them easier to eat in the casserole. This is a matter of personal preference.

### Step 2: Make the Cream Sauce

1. **Melt the Butter:** In a large saucepan or Dutch oven, melt the butter over medium heat. Make sure the butter is fully melted and shimmering before proceeding.
2. **Whisk in the Flour:** Add the flour to the melted butter and whisk constantly for 1-2 minutes, creating a roux. This will help thicken the sauce. The roux should be smooth and pale golden in color.
3. **Gradually Add the Milk:** Slowly pour in the milk, whisking continuously to prevent lumps from forming. Start with a small amount of milk and gradually add the rest, whisking until the sauce is smooth.
4. **Simmer the Sauce:** Bring the sauce to a simmer over medium heat, stirring occasionally. Reduce the heat to low and simmer for 5-7 minutes, or until the sauce has thickened slightly. Be sure to stir frequently to prevent the sauce from sticking to the bottom of the pan.
5. **Season the Sauce:** Stir in the salt, pepper, cayenne pepper (if using), and nutmeg. Adjust the seasonings to your liking.
6. **Add the Cheese:** Remove the saucepan from the heat and stir in the Gruyere (or Swiss) cheese and Parmesan cheese until melted and smooth. The residual heat from the sauce will melt the cheese easily.
7. **Stir in the Sherry and Parsley:** Stir in the dry sherry (if using) and chopped fresh parsley. The sherry adds a depth of flavor to the sauce, while the parsley adds a fresh, herbaceous note.

### Step 3: Assemble the Casserole

1. **Combine Seafood and Sauce:** Gently fold in the cooked shrimp (or raw shrimp, if not pre-cooking) and crab meat into the cheese sauce. Be careful not to break up the crab meat too much.
2. **Pour into Baking Dish:** Pour the mixture into a greased 9×13 inch baking dish. Ensure the mixture is evenly distributed in the dish.

### Step 4: Prepare the Topping

1. **Combine Topping Ingredients:** In a small bowl, combine the panko breadcrumbs, melted butter, grated Parmesan cheese, and chopped fresh parsley. Toss to combine until the breadcrumbs are evenly coated with butter and cheese.
2. **Sprinkle Topping over Casserole:** Sprinkle the breadcrumb mixture evenly over the top of the casserole. This will create a golden, crispy crust.

### Step 5: Bake the Casserole

1. **Preheat Oven:** Preheat your oven to 375°F (190°C).
2. **Bake the Casserole:** Bake the casserole for 20-25 minutes, or until the topping is golden brown and the sauce is bubbly. If using raw shrimp, bake for 30-35 minutes, or until the shrimp is cooked through and opaque.
3. **Let Rest:** Let the casserole rest for 5-10 minutes before serving. This allows the sauce to thicken slightly and prevents it from being too runny.

## Tips and Variations

* **Use Fresh Seafood:** For the best flavor, use fresh shrimp and crab meat. If using frozen shrimp, thaw them completely before using.
* **Don’t Overcook the Seafood:** Overcooked shrimp and crab meat can become tough and rubbery. Be careful not to overcook them.
* **Add Vegetables:** Add chopped vegetables like mushrooms, bell peppers, or celery to the casserole for added flavor and nutrition. Sauté the vegetables before adding them to the sauce.
* **Spice it Up:** Add a pinch of red pepper flakes or a dash of hot sauce to the sauce for a little extra heat.
* **Use Different Cheeses:** Experiment with different types of cheese, such as cheddar, Monterey Jack, or pepper jack.
* **Add a Splash of Wine:** Substitute some of the milk with white wine for a richer, more complex flavor.
* **Make it Gluten-Free:** Use gluten-free flour and gluten-free breadcrumbs to make this casserole gluten-free.
* **Individual Casseroles:** Prepare the casserole in individual ramekins for a more elegant presentation. Reduce the baking time accordingly.
* **Add Some Greens:** Stir in some spinach or kale during the last few minutes of cooking for added nutrition and color.
* **Lemon Zest:** Add lemon zest for a bright and citrusy note.
