I love a good crab cake! It is so good to eat in a sandwich, these Air Fryer Potato Fries, or some fresh summer salad.

So I am going to this healthy version of Maryland Style crab cakes are pretty legit.

Because Tom’s family is from Maryland! So he can vouch for that!



Now his parents just moved to Charleston, SC after retirement. Our must-order is still crab cakes whenever we visit them!

During this stay home quarantine, we have been craving a good Maryland crab cake a lot.

There fore, I set out to create a delicious crab cake recipe that doesn’t have all of those unnecessary ingredients but doesn’t lack any of that Maryland Style jumbo lump crab cake goodness.


What are Maryland Crab Cakes?



The signature ingredient in a Maryland crab cake is the iconic Maryland Blue Crabmeat.

‘Restaurant style’ crab cakes tend to have large chunks of crab meat, making it the star of the show.

‘Boardwalk style’ crab cakes generally have smaller pieces of crab meat with breadcrumbs and Old Bay seasoning.

Traditionally, they are breaded and deep-fried to give them that golden crunchy crust with a delicate center. 


What Makes These Keto Crab Cakes Healthy?



When it comes to making healthy recipes, I like to keep it simple with minimal ingredients. This recipe only calls for 8 ingredients: 


  1. Whole 30 approved mayo
  2. Egg
  3. Dijon mustard
  4. New Bae Seasoning (or old bay)
  5. Chopped fresh parsley
  6. Lemon juice
  7. Jumbo lump crab meat, drained
  8. Coconut flour


Keto: Low Carb, High Protein

Since these keto crab cakes have no filler, they are made up of mostly crab meat (hello protein!), packed with protein and low in carb.


Whole30 Friendly



I used Whole 30 approved condiments like this


that are made with all clean and wholesome ingredients.


Coconut Flour to Replace Breadcrumbs


Instead of breadcrumbs used in traditional crab cake recipes, I used coconut flour to keep this recipe gluten-free and low carb/keto-friendly.


No Frying Needed


In addition to using all healthy ingredients, these keto crab cakes are baked instead of fried so you can eat them guilt-free.


What Type of Crab Meat Should I Use?



As I previously mentioned, Maryland crab cakes typically use meat from the Maryland Blue Crab.

Jumbo lump crab meat is going to be the best option for these crab cakes, and whatever kind of crab meat that you can get fresh is best.

Remember: the fresher the better!

Since the crab meat is the main ingredient in this recipe.

I would suggest avoiding canned crab meat and stick to what is available at your seafood counter.

If jumbo lump crab meat is a little out of your budget, you could also use lump crab meat or backfin as long as it’s fresh!


How to Serve These Maryland Crab Cakes



These carb cakes are so versatile, they can be served with a variety of side dishes.

One of my favorite ways to serve these crab cakes is with a nice piece of corn on the cob, but these crab cakes also go great on top of a bed of greens and made into a salad.

My air fryer potato fries are the perfect starchy side dish or you can serve them with some roasted/grilled veggies if you want to keep things low carb. 


Tips for the Perfect Keto Crab Cakes


This crab cake recipe really is simple, but to give you even more confidence I’ve included some of my no-fail tips to making the perfect crab cake.


  • Drain the crab meat



Too much moisture will make it hard to form and can easily fall apart during cooking.


  • GENTLY mix in the crab meat


You want to keep the lumpiness of the meat intact for this recipe, so be sure you’re mixing carefully to make sure the crab meat doesn’t break apart.


  • Let the mixture marinate in the fridge.

Letting your mixture sit in the fridge for at least an hour will make this recipe more flavorful, and it will provide a better texture/consistency for forming your crab cakes as well.

The coconut flour will help absorb some of the moisture making it easier to shape.

If possible, let your mixture sit overnight for the best results. 


  • Fresh is best.

Remember to use the freshest crab meat that you can find for any crab cake recipe.
