The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

1 cup crabmeat, picked over for shells – Lump crabmeat is best, but claw meat works beautifully too.
1 cup shredded sharp cheddar cheese – Sharp cheddar gives the best flavor. Shred it fresh for the best melt.
½ cup mayonnaise – Use a good-quality mayonnaise like Duke’s or Hellmann’s.
24 cocktail rye bread slices – These small, square slices of rye bread are the perfect base.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat the oven to 375°F and line a baking sheet with parchment paper or lightly grease it.

Pro Tip: Parchment paper makes cleanup a breeze and prevents the cheese from sticking to the pan.

Step 2: Mix the Topping

In a medium bowl, stir together the crabmeat, cheddar cheese, and mayonnaise until evenly combined. The mixture should be creamy and spreadable.

Pro Tip: Be gentle when mixing—you want to keep the crabmeat in nice chunks, not mash it into a paste.

Step 3: Arrange the Bread

Arrange the cocktail rye bread slices on the prepared baking sheet.

Pro Tip: Leave a little space between each slice so they toast evenly.

Step 4: Top and Spread

Spoon a heaping tablespoon of the crab mixture onto each slice and spread it to the edges.

Pro Tip: Spread the mixture all the way to the edges—this ensures every bite has crab and cheese.

Step 5: Bake to Golden Perfection

Bake for 10 to 12 minutes, or until the tops are bubbling and the edges of the bread are crisp and golden brown.

Pro Tip: Watch them closely toward the end. The cheese can go from golden to burnt quickly.

Step 6: Cool and Serve

Let them cool for 2 to 3 minutes, then transfer to a platter and serve warm.

Pro Tip: Serve warm or at room temperature. They’re delicious either way!
