Gather the ingredients for these crab rolls
For the homemade mayonnaise that flavors and binds the filling of these rolls, you’ll need a large egg yolk, Dijon mustard, fresh lemon juice, a neutral oil like grapeseed or canola, and sea salt, to taste. For the crab filling itself, you’ll want fresh crab meat — this can come frozen as well, you don’t actually have to break apart a crab that very moment, but just skip the imitation crab or canned stuff. You’ll also need finely chopped chives, lemon zest, more sea salt, and white pepper. For the garlic butter sauce, you’ll want to grab unsalted butter, garlic cloves, shallots, dry vermouth, and fresh lemon juice. And for assembling the rolls, you’ll want some fresh brioche rolls, flaky sea salt, and more finely chopped chives.
Step 1: Blend the mayonnaise base
In a blender or using an immersion blender, blend the egg yolk, mustard, and lemon juice until combined.
Step 2: Add the oil
With the blender running, slowly drizzle in the oil until the mayo is emulsified and thick. Season with salt to taste and keep chilled till ready to use.
Step 3: Fold crab with the mayonnaise
Gently fold the crab meat with the homemade mayonnaise, chives, lemon zest, salt, and white pepper. Taste and adjust seasoning.
Step 4: Melt the butter
In a small saucepan, melt the butter over medium heat.
Step 5: Add garlic and shallots
Add the garlic and shallots; sweat until translucent, about 2-3 minutes.
Step 6: Deglaze the pan
Deglaze the pan with the vermouth, and cook until reduced by half.
Step 7: Add lemon juice
Remove from the heat and stir in lemon juice.
Step 8: Add garlic butter to the buns
Brush the brioche rolls with the warm garlic butter sauce.
Step 9: Fill the buns
Fill them with the crab mixture, drizzle the remaining sauce over the top, and finish with flaky sea salt.
Step 10: Sprinkle with chives
Top with remaining chives and serve immediately.

What are some tips for making the best homemade mayonnaise?
If you’ve ever found yourself wondering how to make classic homemade mayonnaise, then we’re here for you. What can often feel like an intimidating task is actually rather simple once you understand the science and technique behind it. The foundation of good mayonnaise lies in creating a stable emulsion between egg yolks and oil. To avoid your mayonnaise breaking, always start with room-temperature ingredients, as cold yolks resist proper emulsification. Opt for a neutral base oil like sunflower or grapeseed oil, as olive oil can become bitter and be rather overpowering.
The most critical aspect is the incorporation rate: after whisking your egg yolks with a teaspoon of acid (lemon juice or vinegar), add the oil literally drop by drop at first while emulsifying with a whisk or a blender, ensuring each addition is fully incorporated before adding more. Only once you see the mixture thickening can you gradually increase to a thin stream.
If your mayonnaise “breaks” or separates, don’t discard it. You can salvage it by whisking a fresh yolk in a clean bowl and slowly incorporating it into the broken mixture. Also, working with smaller quantities makes the process easier. And that’s really all there is to nailing your homemade mayo!
How can I switch up these crab rolls?
We tried to keep our recipe for crab rolls with garlic butter as simple as possible to really let the crab flavor shine through. But if you’re open to experimentation, there are plenty of directions you can go with this.
For a spicier version, incorporate 1-2 teaspoons of sriracha or sambal oelek into the crab mixture, or add a pinch of hot smoked paprika and cayenne, or finely diced jalapeños for heat. To go in an Asian-inspired direction, sub cilantro for the chives, and add to the mayo base with a teaspoon of grated ginger, a splash of sesame oil, and a dash of rice vinegar. For a Mediterranean twist, mix the crab salad with 2 tablespoons of finely chopped sun-dried tomatoes, 1 tablespoon of capers, and fresh basil instead of chives.
You can also serve the filling on kaiser or pretzel rolls instead of brioche rolls, or go with croissants or even butter-toasted Hawaiian sweet rolls for a sweet-and-salty combo. Adding some thinly sliced cucumber, crispy bacon bits, or Parmesan would also be a great touch. The garlic butter sauce could be transformed by incorporating curry powder, Old Bay seasoning, or even a tablespoon of miso paste for umami depth. You can even lighten the salad by replacing half the mayonnaise with Greek yogurt and adding extra lemon zest for a brighter flavor.
