Introduction

This Hot Crab Dip with Old Bay Crostini is a creamy, flavorful appetizer perfect for gatherings or a cozy night in. Packed with fresh crabmeat and melted cheeses, it pairs beautifully with crunchy, seasoned baguette slices. It’s easy to make and sure to impress your guests.

A white cup filled with a creamy, slightly chunky dip, with visible green chive pieces on top. One toasted round bread chip is partially dipped in the creamy mixture. The cup sits on a white rectangular plate with scattered toasted round bread chips around it, all showing a browned, crispy texture. There are three lemon wedges on the plate near the cup, adding a bright yellow contrast. A small purple flower sits on the edge of the cup, and the whole scene is set on a white marbled surface.

Ingredients

1 baguette, sliced into rounds
4 tablespoons softened butter
Old Bay seasoning
4 ounces cream cheese, softened
½ cup mayonnaise
⅓ cup sour cream or plain Greek yogurt
1 pound lump crabmeat
3 garlic cloves, minced
2 green onions, thinly sliced
¼ cup chopped fresh parsley
1 teaspoon Dijon mustard
1 teaspoon dried chives
½ teaspoon dried dill
1 pinch crushed red pepper flakes
1 teaspoon freshly grated lemon zest
4 ounces cheddar cheese, freshly grated
4 ounces Gruyere cheese, freshly grated
Kosher salt and pepper
Fresh chives, for topping

Instructions

Step 1: Preheat your oven to 400 degrees F.
Step 2: In a bowl, mix the cream cheese, mayonnaise, and sour cream until creamy and smooth. Stir in the crabmeat, minced garlic, green onions, parsley, Dijon mustard, dried chives, lemon zest, crushed red pepper flakes, dried dill, and a generous pinch of kosher salt and pepper. Fold in the grated Gruyere and cheddar cheeses until evenly combined.
Step 3: Spread the crab mixture evenly into a baking dish, such as a 9-inch pie plate or a similar-sized square dish. Bake for 25 to 30 minutes, until the dip is bubbling and golden on top. Optionally, garnish with fresh chives or herbs before serving.
Step 4: To make the Old Bay crostini, spread softened butter on each baguette slice and sprinkle with Old Bay seasoning to taste. Arrange the slices on a baking sheet and bake for 10 to 12 minutes, or until crisp and golden. Serve warm alongside the hot crab dip.

Tips & Variations

Use lump crabmeat for the best texture, but canned crab works in a pinch.
Swap sour cream for Greek yogurt to lighten the dip without sacrificing creaminess.
Add a squeeze of fresh lemon juice into the dip for extra brightness.
For a spicy twist, increase the crushed red pepper flakes or add a dash of hot sauce.

Storage

Store leftover crab dip in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350 degrees F until warmed through, or microwave in short bursts to avoid overcooking. Keep crostini separate to maintain their crispness.
