Instructions
- Pick and Prep the Crab
Gently rinse the lump crab meat in a fine sieve, pat it very dry with paper towels, then transfer it to a medium bowl and flake it with your fingers to remove any tiny bits of shell.
- Make the Crab Mixture
To the crab, add mayonnaise, Dijon mustard, garlic powder, onion powder, black pepper, lemon juice, and parsley. Stir gently until everything is evenly coated and set the bowl aside.
- Warm the Buns Lightly
Split the buns in half and spread a thin layer of softened butter on the cut sides. Heat a large skillet over medium low heat and add olive oil, then lay the bun halves cut side down for one to two minutes until just golden and fragrant.
- Start the Melt
Turn the heat to medium, place a few slices of cheddar on the bottom bun halves, and let the first side begin to soften so the cheese acts as a glue for the crab mixture.
- Add the Crab Mixture
Divide the crab mixture evenly among the four bun bases, spreading it gently into an even layer so every bite has plenty of flavor.
- Top and Press Gently
Lay the remaining cheddar slices on top of the crab mixture, place the bun tops over the cheese, and very gently press down with a spatula so the sandwich holds together without squishing the crab.
- Toast Until the Cheese Melts
Cover the skillet for two to three minutes so the cheese inside melts completely, then uncover and toast each side for one to two minutes longer until the bread is deep golden and crisp.
- Rest and Serve
Let the sandwiches rest in the pan for two minutes before transferring them to a plate so the filling sets slightly and the cheese stops sliding.
Substitutions and variations
- Use imitation crab or cooked, flaked salmon if you prefer a different flavor or cost option.
- Swap sharp cheddar for Monterey Jack or provolone for a milder melt.
- Replace mayonnaise with Greek yogurt for a lighter tang.
- Use a gluten free bun if you need a gluten free version.
- Add a thin slice of red onion for extra crunch and color.
Chloe's tips
- Pat the crab very dry so the sandwich stays easy to handle and the butter can crisp the bun instead of making it soggy.
- Low and steady heat is key to melting the cheese without burning the buttery bun.
- For extra richness, add a thin swipe of garlic butter under the cheese slices.
- Let the sandwich rest for a minute after toasting to avoid losing filling when you take that first bite.
How to store it
- These sandwiches are best enjoyed right away while the cheese is gooey and the bun is crisp.
- Store any leftovers in an airtight container in the fridge for up to 2 days and reheat gently in a low oven or toaster oven to refresh the texture.
Serving suggestions
Serve these crab melt sandwiches as a relaxed dinner with a simple salad and lemon wedges for brightness.
- Pair with oven roasted broccoli or a light green salad
- Serve with lemon wedges for a quick brightness boost
- Add thinly sliced radish or cucumber for extra crunch
- Enjoy with a glass of crisp white wine or sparkling water with citrus
Frequently asked questions
Can I make crab cakes instead of using buns
Absolutely, form the crab mixture into patties, chill them briefly, then pan sear or bake until golden for delicious crab cakes.
How do I keep the bun from getting too soggy
Pat the crab mixture dry, add the cheese while the bun bottom is still hot to create a light barrier, and assemble just before serving.
Can I make this in the air fryer
Yes, assemble the sandwiches, brush the outsides with a little oil, and air fry at 350°F for 6 to 8 minutes until the cheese melts and the bun is golden.
What if I do not have Dijon mustard
A little yellow mustard or a squeeze of extra lemon juice will work fine and still keep the flavor bright.
