Crab Cakes with Old Bay Aioli

Crab cakes are a classic American seafood dish, especially associated with the East Coast, where sweet crab meat is shaped into small patties with just enough binder to hold it together. The best versions keep the crab at the centre: tender and flaky inside, crisp and golden on the outside, with seasoning that supports rather than overwhelms. Here, Old Bay brings its familiar celery-salt warmth and gentle spice, while a lemony mayonnaise aioli adds richness, acidity and a savoury dip for serving. They work well as a starter, light dinner or sharing plate, particularly when served hot with extra lemon at the table.

Why this recipe works

  • Crisp outside, tender centre: Pan-frying gives the cakes a golden crust while keeping the crab mixture soft and delicate inside.
  • Richness with lift: Lemon zest and juice cut through the mayonnaise-based aioli, keeping the sauce bright rather than heavy.
  • Simple shaping method: A short chill helps the cakes firm up before frying, making them easier to turn without overworking the crab.

Texture tips

  • Keep the crab pieces intact: Fold the crab in gently and stop mixing as soon as the mixture holds together; this keeps the cakes light rather than dense.
  • Let the crust form before turning: Give each side time to become deep golden before moving the cakes, as turning too early can make them break apart.

Ingredient notes

  • Check the crab carefully: Picked crab meat can still contain small shell fragments, so feel through it before mixing.
  • Old Bay sets the flavour: The seasoning brings celery salt, paprika and warming spice notes, giving the cakes their recognisable American seafood character.

Make-ahead tips

  • Shape before frying: The crab cakes can be shaped and chilled shortly before cooking, which helps them hold together in the pan.
  • Keep the aioli separate: Store the aioli chilled and separate from cooked crab cakes so the sauce stays fresh and the cakes are easier to reheat.

Serving ideas

  • Serve with something crisp: A simple green salad, slaw or lightly dressed leaves balance the richness of the fried cakes and aioli.
  • Finish with lemon: A final squeeze of lemon at the table sharpens the seafood flavour and brightens the sauce.

  1. Make the aioli: in a small bowl, stir together the mayonnaise, finely grated lemon zest and 1 tbsp lemon juice with 1 tsp Old Bay seasoning until smooth. Cover and chill while you make the crab cakes.
  2. Trim and finely slice the spring onion. In a mixing bowl, whisk the egg with the Dijon mustard and the remaining 1 tsp Old Bay seasoning.
  3. Add the spring onion and breadcrumbs to the bowl and mix to combine. Gently fold in the crab meat, keeping some larger pieces for texture, until the mixture just holds together.
  4. Shape the mixture into 8 small cakes and place them on a plate. Chill for 10 minutes so they firm up and are easier to fry.
  5. Heat the vegetable oil in a frying pan over a medium heat. Pan-fry the crab cakes for 3 to 4 minutes per side until deep golden and hot through, turning carefully with a spatula.
  6. Serve the crab cakes straight away with the Old Bay aioli on the side. Add an extra squeeze of lemon at the table if you like.

Recipe notes

Tips

  • Handle the crab mixture gently so the cakes stay light and you keep some larger pieces of crab.
  • If the cakes feel fragile, chill them for an extra 10 minutes before frying to help them hold their shape.
  • If serving to pregnant people, young children, older adults, or anyone immunocompromised, use pasteurised egg or ensure the egg is thoroughly cooked through in the crab cakes.

Substitutions

  • Replace Dijon mustard with whole-grain mustard for a coarser texture.
  • Replace Breadcrumbs with panko breadcrumbs for a lighter, crunchier crust.

Storage

  • Refrigerate up to 2 days
  • Cool leftover crab cakes, then refrigerate in a sealed container. Reheat in a frying pan over a low to medium heat with a little vegetable oil for 2 to 3 minutes per side until piping hot; the aioli is best kept chilled and stirred before serving.
