What’s not to love about these keto crab cakes? They are:

  • simple to make
  • gluten-free
  • grain-free
  • dairy-free
  • keto-friendly and low-carb

A quick disclaimer for you that is absolutely essential for me to make clear before you embark on your low-carb crab-cake-making process: these disappear quickly. Like, record-time in my house. And given that one batch will yield six crab cakes, I recommend doubling or even tripling the recipe if you’re making these crab cakes for a crowd (or if your people are extra hungry).

ingredients in keto crab cakes

If you’ve ever made homemade crab cakes, you know the crab cake recipe usually calls for a type of filler- saltine crackers, breadcrumbs, etc.- definitely not low-carb. Wonderful news: you don’t need any of that. Delicious crab cakes are still doable without the high-carb, high-gluten filling.

Instead of breadcrumbs, this keto crab cake recipe calls for coconut flour and… crushed pork rinds.

Yup, and it’s downright magical.

  • sriracha (or hot sauce of your choice)
  • nutritional yeast (optional)

Is imitation crab keto?

I do not suggest using imitation crab, as it will affect the flavor and the nutritional profile of these keto crab cakes. Imitation crab is made from a type of white fish that is then treated with added starches, flavoring, and sugar, in order to taste like the real thing. Because of the additives, it’s not a very keto-friendly option. Plus, wild-caught crab is better in every way and you can usually find wild-caught lump crab meat pretty easily.

the crab cake recipe to try!

To make these keto crab cakes, follow this simple recipe:

  1. Mix together the wet ingredients. In a small bowl, whisk together the mayonnaise, egg, Worcestershire sauce, mustard, lemon juice, and sriracha.
  2. Combine dry ingredeints. In a larger mixing bowl, combine the coconut flour, nutritional yeast, salt, pepper, crushed pork rinds, paprika, onion and parsley. Stir in the wet mixture. Add the crab meat and gently fold it in until the crab cake batter is evenly combined. Refrigerate (optional) or move on to frying.
  3. Fry the crab cakes. Heat the ghee or avocado oil in a large skillet at a medium-high temperature. Use an ice cream scoop to spoon out crab cake batter and gently form the crab cakes in your hands, flattening the out slightly. Place each crab cake in the skillet and pan-fry for about 3 minutes per side. You want each side a deep golden brown.
  4. Serve. Remove them from the pan and allow them to cool on a paper towel-lined plate. Serve warm with the lemon aioli (recipe below!).

the easiest lemon aioli recipe

Lemon aioli isn’t a must, but if you want to take the keto crab cakes to the next level, this is how. Creamy and slightly tart, it’s a lovely dip for the crab cakes that compliments- but doesn’t overpower- that irresistible crab flavor.

pro tips for keto crab cakes

  • These keto crab cakes with coconut flour hold together well, but to get them even more firm, refrigerate for an hour (or even overnight).
  • Be careful not to over-mix the crab cake batter after adding in the lump crab meat. Fold it in gently to keep those meaty chunks from breaking down.
  • Don’t squash the crab cakes when you’re forming the patties. Gently press them together so they’re about 3/4-inch thick, then place them directly in the pan.
  • Keto crab cakes will store well in the refrigerator for at least two days. To reheat them, bake them in the oven at 350°F for about 5-8 minutes, or until they’re heated through. This reheating method will help prevent them from getting soggy.

These keto crab cakes are no-fuss, quick to assemble, and work for any occasion, any time of day! Throw a crab cake in between some low-carb bread or enjoy one on top of a salad. Crab cake eggs Benedict? I’m all in. Extra lemon aioli, always.

Do not substitute coconut flour for almond flour-- they are not 1:1 swaps.
