Ingredients

Butter
Scallions
Parsley
Flour
Half and Half
Swiss Cheese
Sherry
Ground Red Pepper
Fresh Crabmeat
Puff Pastry Shells (optional, for entrée)

How to Make It Step-by-Step

Melt the butter: Start by melting half a cup of butter in a heavy medium-size saucepan over medium heat. Allow it to melt slowly, ensuring it doesn’t brown.
Sauté the scallions and parsley: Add the minced white parts of the scallions and the chopped parsley to the butter. Sauté them for 1-2 minutes until they become fragrant. This step brings out the savory flavors that will form the base of your dip.
Make the roux: Sprinkle in the flour and whisk continuously. Cook the flour for 1-2 minutes to form a roux. This will thicken the mixture and give the dip a creamy texture.
Add the half and half: Gradually pour in the half and half while whisking constantly. Keep whisking until the mixture becomes smooth, ensuring no lumps form.
Melt the cheese: Stir in the shredded Swiss cheese, and whisk until it’s completely melted and incorporated into the sauce. The cheese gives this dip its rich, velvety texture.
Add the sherry and red pepper: Pour in a tablespoon of sherry, followed by ground red pepper to taste. Stir well to combine, allowing the flavors to meld together. The sherry adds a subtle depth and warmth to the dip, while the red pepper gives it a gentle kick.
Fold in the crab: Finally, gently fold in the fresh crabmeat, being careful not to break up the chunks. You want those big, beautiful pieces of crab to stay intact. Heat the mixture for a few minutes, ensuring it’s evenly warm.
Serve: If making this ahead, you can store the dip in the fridge until you’re ready to serve. When you’re ready, simply reheat it over low heat. To serve, spoon the dip into a chafing dish or a serving bowl, garnish with additional parsley or chopped scallion greens, and serve with toasted baguette slices or toast points.
For an elegant entrée: If you’re serving this as an entrée, fill puff pastry shells with the hot crab mixture. Bake according to the package instructions for the puff pastry, then serve warm, garnished with parsley or scallions.

Tips for Best Results

Low and slow: When making the roux, be sure to cook the flour over medium heat and not too quickly. This allows the flavors to develop and prevents the sauce from becoming too thick or lumpy.
Use fresh crab: For the best flavor, opt for fresh, high-quality crabmeat. Whether you use fresh claw or lump crabmeat, the crab will be the star of the dish, so make sure it’s the best you can find.
Don’t overheat the mixture: Once the cheese is melted and the crab is added, you don’t need to cook it much longer. Just heat it until everything is warm and incorporated. Overheating can cause the cheese to separate or become oily.
Make it ahead: This dip is perfect for making ahead! You can prepare the filling the day before, refrigerate it, and then simply reheat it when it’s time to serve. It’s a real time-saver for busy hosts.

Ingredient Substitutions & Variations

While this recipe is fantastic as-is, there are several ways you can customize it to suit your tastes or dietary preferences:

Vegan option: For a vegan-friendly version, substitute the butter with vegan butter, the cheese with vegan Swiss cheese, and replace the half and half with a plant-based alternative, such as almond or coconut milk. You can also use vegan crab substitutes if desired.
Spice it up: If you love a bit of heat, consider adding a pinch of cayenne pepper or a dash of hot sauce to the mix for a spicy kick.
Use different cheeses: While Swiss cheese is the classic choice for Crab Mornay, you can experiment with other cheeses like Gruyère or Monterey Jack for a different flavor profile.
More veggies: Add a handful of sautéed spinach or mushrooms to the dip to make it more hearty and give it a delicious, earthy flavor.

Serving Suggestions

This creamy crab dip is incredibly versatile, and you can serve it in several ways:

As an appetizer: Serve the dip with toasted baguette slices, crackers, or vegetable sticks like celery, cucumber, and bell peppers for dipping.
As an entrée: Serve the crab mixture in baked puff pastry shells, making for an elegant entrée that will impress your guests at any dinner party.
For a holiday spread: This dip is perfect for the holidays! It pairs beautifully with other appetizers like Redneck Caviar or a simple deviled egg platter.

Pairing Ideas (Drinks, Sides, etc.)

Drinks: Pair this creamy crab Mornay with a crisp glass of white wine like Sauvignon Blanc or Chardonnay. If you prefer non-alcoholic beverages, try serving it with sparkling water or a citrusy lemonade.
Side dishes: Complement the richness of the dip with light and fresh sides such as a crisp green salad, roasted vegetables, or a fruit platter.

How to Store and Reheat Leftovers

If you have any leftovers (which is unlikely, but if you do…), here’s how to store and reheat the dip:

Refrigerator: Let the dip cool completely, then store it in an airtight container in the fridge for up to 3 days. When you’re ready to eat, simply reheat it over low heat, stirring occasionally to avoid separation.
Freezer: You can freeze the dip for up to 2 months. To reheat, thaw overnight in the fridge, then warm it up in a saucepan over low heat.

Make-Ahead and Freezer Tips

This recipe is ideal for make-ahead preparation. You can prepare the filling a day in advance and refrigerate it, then reheat it when you’re ready to serve. If you’re short on time, making it ahead means you can spend more time enjoying your party and less time in the kitchen.

Common Mistakes to Avoid

Overheating the cheese: When adding the cheese, make sure the heat is low. Overheating can cause the cheese to separate, making the dip greasy rather than creamy.
Not using fresh crab: Using canned crabmeat might save a few dollars, but it won’t provide the same rich flavor and texture that fresh crab will.
Not letting it cool: Allow the dip to cool slightly before serving. If it’s too hot, it will be hard to scoop up without burning your fingers.
