Featured on Bring on the Karbs, hosts Erica and Josh Karbelnik transform a simple seafood sandwich into a flavor-packed meal that balances richness, freshness, spice, and texture in every bite.

Perfect for lunch, casual entertaining, or seafood lovers looking for a new sandwich recipe, this crab baguette showcases how a few carefully chosen ingredients can create a restaurant-worthy experience at home.

The Inspiration

Few ingredients evoke coastal comfort quite like fresh crab. From crab cakes and seafood boils to chilled crab salads and lobster rolls, sweet crab meat has long been celebrated for its delicate flavor and versatility.

In this episode of Bring on the Karbs, Erica and Josh Karbelnik explore the concept of “Long and the Short of It” through ingredients and presentation. The long baguette serves as the foundation for a sandwich that delivers layers of flavor and contrasting textures.

The quick-pickled onions add brightness and acidity, cutting through the richness of the crab mixture. Fresh scallions contribute a mild onion flavor, while lemon zest and juice bring freshness that highlights the natural sweetness of the seafood.

Ingredients

8 oz premium crab meat
½ cup unsalted butter at room temperature
1 long baguette
½ cup mayonnaise
1 tsp smoked paprika
1 tsp ground celebrity seed
1 tsp ground ginger
3 ground bay leaves plus 1 whole bay leaf
½ tsp white pepper
1 tsp cracked black pepper
1 tsp cayenne pepper
1/8 tsp ground nutmeg
1/8 tsp ground cardamom
1/8 tsp ground allspice
1/8 tsp ground cinnamon
¼ tsp mustard powder
Juice and zest from 1 lemon
1 bunch scallions
1 head iceberg lettuce, shredded
1 tbsp tabasco sauce
1 red onion
½ cup white vinegar
½ cup water
1 tbsp sugar
1 tbsp salt
2 sprigs dill

Method

Add vinegar, water, sugar, salt, bay, and dill to a pot and bring to a boil.
Slice the red onion, place it in a bowl, and pour over the boiling vinegar mixture. Cover and let sit to quick pickle the onion.
In a bowl, mix crab with mayonnaise, spices, lemon, scallion, and hot sauce.
Cut baguette in half lengthwise and rip out bread from the center to make a boat for the sandwich fillings. Spread butter on the bread and grill cut side down until charred.
Fill one baguette half with lettuce, top with crab mix, pickled onions, and remaining baguette half and serve.

Serving Suggestions

This Old Bay Crab Baguette Sandwich is ideal for warm-weather lunches, casual entertaining, seafood-themed dinners, or weekend gatherings with friends and family. The sandwich pairs beautifully with kettle-cooked potato chips, crispy fries, coleslaw, or a simple cucumber salad. For a lighter meal, serve it alongside mixed greens dressed with a lemon vinaigrette that echoes the citrus notes in the crab filling.

Because the sandwich contains rich seafood flavors balanced by fresh vegetables and pickled onions, it also works exceptionally well for outdoor dining, picnics, and summer celebrations. Presenting the sandwich on a wooden serving board with extra pickled onions and lemon wedges creates an inviting presentation that highlights its coastal-inspired character.
