I’ve always had a soft spot for crab melts. Something about that buttery bread, warm cheese, and seasoned crab meat takes me straight back to summer afternoons near the coast. It’s the kind of sandwich that doesn’t just taste good — it feels a little nostalgic.

This version is my go-to when I want something satisfying but not too fussy. A few fresh ingredients, a little Old Bay seasoning, and a few minutes in the oven — and suddenly, you’ve got a sandwich that feels special.
Why This Recipe Works So Well
A crab melt works because it’s simple and lets the crab shine. I’ve tried adding too many ingredients before, and every single time, it only masked the delicate flavor of the crab. So now, I keep it classic: good lump crab meat, just enough mayonnaise to bind, a hit of lemon juice to brighten, and Old Bay to give it that familiar Maryland-style flavor.
The real magic happens in the oven. The bread gets golden and crisp, the cheese melts just slightly over the edges, and that buttery crab filling warms up beautifully. It’s the kind of sandwich that makes you slow down for lunch.
Ingredients You’ll Need
-
Lump Crab Meat – Fresh crab is best, but canned works too. Just make sure to drain it well.
-
Old Bay Seasoning – This gives the crab its signature flavor.
-
Mayonnaise – Just enough to bind everything without overpowering the crab.
-
Lemon Juice – A touch of acidity brightens the flavors.
-
Celery and Red Onion – Add a bit of crunch and freshness.
-
Parsley – A sprinkle for color and a clean finish.
-
Cheese – Cheddar or Swiss work great; pick the one you love.
-
Bread – I like using Tuscan garlic bread or sourdough, but English muffins and French bread are just as good.
-
Butter – For brushing on the bread so it toasts beautifully.

Step-by-Step: How I Make Crab Melts
Mix the Crab Filling
I start by mixing the mayonnaise and lemon juice together in a bowl until smooth. Then I gently fold in the crab meat — you don’t want to break it up too much. A sprinkle of Old Bay seasoning goes in next, along with celery, red onion, and parsley. A little black pepper finishes it off.
Prep the Bread
I brush melted butter on one side of each bottom bread slice. This gives the bread that golden, crisp exterior. Then I spread the crab mixture generously on top.
Add the Cheese
A slice of cheese goes right over the crab filling. I usually let the edges of the cheese hang over a bit because it melts down and creates those irresistible cheesy drips on the sides.
Top and Bake
I place the buttered top slices over the cheese and bake at 400°F for about 5 minutes on one side, then flip and bake for another 3 to 4 minutes. Finally, I switch to broil for just a minute or two to get that gorgeous, toasty finish.
How to Cook Them Just Right
This part is quick, so it’s best to stay nearby. Crab melts can go from perfectly golden to burnt in a heartbeat under the broiler. I’ve learned to trust my nose — when you start smelling that buttery toast and melted cheese, it’s time to pull them out.
The broiler gives the sandwich that final layer of crispness while keeping the inside soft and warm. It’s a little detail, but it makes all the difference.
What to Serve with Crab Melts
These sandwiches are pretty filling on their own, so I usually keep the sides light. A few tomato slices on top after baking are my favorite touch — I prefer not to bake the tomatoes with the sandwich because they can make it soggy.
Here are a few sides that work well:
-
Simple tomato slices with a pinch of salt
-
Fresh fruit for a refreshing contrast
-
Plain potato chips to keep things light and crunchy
-
A simple side salad with lemon vinaigrette
Tips, Tricks, and Substitutions
-
Skip the extra salt — the Old Bay seasoning is already plenty flavorful.
-
Use good quality lump crab meat if you can. It makes all the difference.
-
Measure your ingredients. A little too much mayo or seasoning can cover the taste of the crab.
-
Add a few drops of hot sauce if you want a little kick.
-
Green onions can replace red onions if that’s what you have.
-
Swiss cheese melts beautifully if you want a slightly milder cheese than cheddar.
-
If you’re on a budget, imitation crab works fine too, though the flavor will be different.
Bread options I love:
-
Tuscan garlic bread
-
Sourdough
-
French bread
-
Ciabatta rolls
-
English muffins (for open-faced melts)
Make Ahead Tips
If I’m planning ahead, I mix the crab filling a few hours before and keep it covered in the fridge. When it’s time to eat, I just assemble the sandwiches and bake them.
This is especially handy if you’re making multiple melts for a gathering or just want dinner to come together quickly after a long day. The flavors actually deepen a bit as the filling rests, making it even better.
Storage
If I have leftovers, I usually pop the cooled crab melts into airtight containers or resealable bags and refrigerate them. They stay good for up to two days.
When reheating, I like to warm them in the oven at 350°F for about 10 minutes. The bread gets its crispness back, and the cheese melts nicely again. They taste almost as good as they did fresh out of the oven.

FAQs
Can I reheat crab melts in the microwave?
Yes, but I prefer the oven because it keeps the bread crisp. If using the microwave, heat in short bursts to avoid making the bread soggy.
Can I make the filling ahead of time?
Yes, the crab mixture can be made several hours in advance. Keep it covered in the fridge until ready to assemble.
Can I freeze crab melts?
I don’t usually freeze them because the texture of crab and mayo can change. It’s best enjoyed fresh or refrigerated for a short time.
What cheese works best?
I love cheddar for its sharp flavor, but Swiss melts really nicely and gives a softer, creamier bite.
Easy Crab Melts with Old Bay Seasoning
This Easy Crab Melt is a crave-worthy twist on the classic tuna melt — creamy, cheesy, and packed with sweet lump crab meat seasoned to perfection.
Ingredients
- 3 tablespoons mayonnaise
- 1 tablespoon lemon juice
- ½ tablespoon Old Bay seasoning
- 6 ounces lump crab meat
- 2 stalks celery, diced
- ⅛ cup red onion, diced
- 1 tablespoon fresh parsley, chopped
- Black pepper, to taste
- 4 slices bread
- 3 tablespoons butter, melted
- 4 slices cheddar cheese
- 1 tomato, sliced (optional)
Instructions
- Preheat the oven to 400°F (200°C).
- In a medium bowl, whisk together the mayonnaise and lemon juice until smooth. Add the crab meat and gently fold it in so it stays chunky. Stir in the Old Bay seasoning, celery, red onion, parsley, and black pepper. Mix until everything is evenly coated.
- Brush one side of each bread slice with melted butter. Arrange two slices on a baking sheet, buttered side down. Top the plain side with a generous layer of the crab mixture, then place a slice of cheddar cheese over each.
- Cover with the remaining bread slices, buttered side facing up.
Bake for about 5 minutes, then carefully flip the sandwiches and bake for another 4 minutes, until golden and crisp. - Turn the oven to broil and broil for 1–2 minutes, keeping a close eye on them, until the tops are a deep golden brown and the cheese is melty.
- If you’d like, tuck a few tomato slices inside each sandwich before serving for a fresh, juicy bite.
Notes
- For the best flavor, use fresh lump crab meat if you can find it. If using canned or refrigerated crab, drain it well before mixing.
- Old Bay seasoning gives the melts their signature flavor, but you can adjust the amount to your taste.
These sandwiches pair beautifully with a simple salad, fries, or a cup of tomato soup.
