This delightful crab sandwich is a perfect blend of creamy and tangy flavors, making it an ideal choice for a quick lunch or a light dinner. The combination of crab meat with mayonnaise, lemon juice, and dijon mustard creates a rich and satisfying filling that pairs wonderfully with crispy, buttery bread.
If you don't usually have crab meat at home, you might need to visit the seafood section of your supermarket. Fresh or canned crab meat can be used, but make sure to check for any shell fragments. Dijon mustard is another ingredient that might not be in your pantry; it adds a subtle tangy flavor that complements the crab perfectly.

How to Store or Freeze Your Sandwich
- Allow the crab sandwich to cool completely before storing. This prevents condensation, which can make the bread soggy.
- Wrap each sandwich tightly in plastic wrap or aluminum foil to maintain freshness and prevent air exposure.
- Place the wrapped sandwiches in an airtight container or a resealable plastic bag to further protect them from moisture and odors.
- Store the sandwiches in the refrigerator if you plan to consume them within 1-2 days. For longer storage, place them in the freezer.
- When freezing, label the container or bag with the date to keep track of storage time. Crab sandwiches can be frozen for up to 1 month.
- To reheat, thaw frozen sandwiches in the refrigerator overnight. For a crispy texture, reheat in a preheated oven at 350°F (175°C) for about 10-15 minutes or until heated through.
- Alternatively, you can reheat the sandwiches in a skillet over medium heat, flipping occasionally, until the bread is crisp and the filling is warm.
- Avoid using a microwave for reheating as it can make the bread chewy and the crab meat rubbery.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the crab sandwich in aluminum foil to retain moisture. Place it on a baking sheet and heat for about 10-15 minutes, or until the crab meat is warmed through and the bread is crispy.
For a quicker method, use a toaster oven. Set it to 350°F (175°C) and place the crab sandwich directly on the rack. Heat for 5-7 minutes, checking frequently to ensure the bread doesn't burn.
If you prefer using a skillet, preheat it over medium heat. Place the crab sandwich in the skillet and cover with a lid to help heat the filling evenly. Cook for about 2-3 minutes per side, or until the crab meat is hot and the bread is golden brown.
For a microwave option, wrap the crab sandwich in a damp paper towel to prevent it from drying out. Microwave on medium power for 1-2 minutes, checking halfway through. Note that this method may make the bread slightly soggy.
If you have an air fryer, preheat it to 350°F (175°C). Place the crab sandwich in the basket and heat for 3-5 minutes, or until the crab meat is warmed through and the bread is crispy.
