Indulge in the delightful flavors of a crab sandwich, a perfect blend of fresh or canned crab meat mixed with creamy mayonnaise, zesty lemon juice, and tangy dijon mustard. This sandwich is a quick and easy way to enjoy a gourmet meal at home, with a crispy, golden-brown exterior and a rich, savory filling.
If you don't usually keep crab meat at home, you might need to visit the seafood section of your supermarket. Fresh crab meat is often found in the refrigerated section, while canned crab meat can be located in the canned goods aisle. Ensure you pick up dijon mustard, which is typically found in the condiment section.

Technique Tip for Making a Crab Sandwich
To ensure your crab sandwich has the best flavor and texture, gently fold the crab meat with the mayonnaise, lemon juice, and dijon mustard to avoid breaking up the delicate meat. Additionally, for an extra layer of flavor, consider adding a pinch of Old Bay seasoning or a dash of hot sauce to the mixture. When toasting the bread, use a medium heat to achieve a perfectly golden crust without burning the butter.

How to Store or Freeze Your Crab Sandwich
- Allow the crab sandwich to cool completely before storing. This prevents condensation, which can make the bread soggy.
- Wrap each sandwich individually in plastic wrap or aluminum foil to maintain freshness and prevent freezer burn.
- Place the wrapped sandwiches in an airtight container or a resealable plastic freezer bag. Label with the date to keep track of storage time.
- Store in the refrigerator for up to 2 days. For longer storage, place in the freezer for up to 1 month.
- To reheat, thaw frozen sandwiches in the refrigerator overnight. Heat in a preheated oven at 350°F (175°C) for about 10-15 minutes or until warmed through. Alternatively, reheat in a frying pan over medium heat until the bread is crispy and the filling is hot.
- Avoid microwaving the sandwiches as it can make the bread chewy and the filling unevenly heated.
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 mixture 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, keeping an eye on it to prevent burning.
If you prefer using a skillet, heat a non-stick pan over medium heat. Add a small amount of butter or olive oil to the pan. Place the crab sandwich in the skillet and cover with a lid. Heat for about 2-3 minutes on each side, or until the crab mixture is warmed through and the bread is crispy.
For microwave reheating, wrap the crab sandwich in a damp paper towel to keep it from drying out. Microwave on medium power for 30-45 seconds. Check if it's heated through; if not, continue in 15-second intervals. 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 mixture is warmed through and the bread is crispy.
