Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Lump crab meat (fresh, canned, or imitation)
Mayonnaise
Cream cheese, softened
Dijon mustard or whole grain mustard
Worcestershire sauce
Lemon juice
Green onions, finely chopped
Old Bay seasoning (or paprika as a substitute)
Salt and black pepper
Shredded sharp cheddar cheese
Bread slices (sourdough, rye, or sandwich rolls work great)
Butter (for toasting the bread)

Directions

I preheat the oven broiler or a toaster oven to high.
In a bowl, I combine the crab meat, mayonnaise, cream cheese, mustard, Worcestershire, lemon juice, green onions, and seasoning. I stir until everything is well mixed and creamy.
I lightly toast the bread slices, then butter one side of each if I’m pan-toasting later.
I spread the crab mixture evenly onto one slice of each sandwich (or open-faced), then top with a generous layer of shredded cheddar cheese.
I place the sandwiches on a baking sheet and broil for 2–4 minutes, watching closely, until the cheese is melted and bubbly and the edges are golden.
I serve the melts hot, either open-faced or topped with another slice of bread, cut in halves.

Servings and timing

This recipe makes 2–4 sandwiches, depending on the size of the bread.

Variations

I sometimes add sliced tomatoes or a layer of spinach for a fresh bite. If I want a spicy version, I mix in a dash of hot sauce or cayenne pepper. For a fancier touch, I use brioche buns or make mini crab melts on English muffins as appetizers. I’ve also made these with a mix of crab and shrimp for extra seafood flavor.

storage/reheating

If I have leftover crab filling, I store it in an airtight container in the fridge for up to 2 days. Assembled sandwiches are best eaten fresh, but I can reheat them in a toaster oven or skillet until warmed through and crispy. I avoid the microwave to keep the bread from turning soggy.

FAQs

Can I use canned or imitation crab?

Yes, I often use canned or imitation crab when fresh isn’t available. I just make sure to drain it well and chop it slightly if needed for better texture.

What cheese works best besides cheddar?

I like sharp cheddar for the bold flavor, but I’ve also used gouda, mozzarella, or even pepper jack when I want a little spice.

Can I make this sandwich ahead of time?

I prepare the crab mixture ahead and refrigerate it, but I assemble and toast the sandwich fresh for the best texture and flavor.

What bread is best for crab melts?

I usually go with crusty sourdough or a soft sandwich roll. English muffins work great for smaller portions, and rye gives a nice earthy balance.

How do I keep the sandwich from getting too rich?

I add a squeeze of lemon juice or serve it with a crisp salad or pickles on the side to cut through the richness.

Conclusion

This Creamy Cheddar Crab Melt Sandwich is everything I love about a quick, flavorful meal—creamy, cheesy, and loaded with satisfying seafood flavor. It’s easy enough for a weeknight but feels like a special treat every time I make it. Whether I’m enjoying it solo or serving it up for guests, it never fails to impress.
