These easy keto crab cakes make a wonderful low carb appetizer or main course. Sweet chunks of blue crab combined with fresh herbs, spices and just enough filler to hold it all together – it’s one of my favorite meals!

This keto crab cakes recipe is an update of a post I wrote in the early days of this website back in 2012. I’ve made a couple of small tweaks to the recipe itself, and I’ve also added some tips to help make sure they come out perfect every time.

My love of crab cakes knows no bounds. If I’m in a restaurant and there are crab cakes on the menu, then I’m ordering them. No questions asked.
Unfortunately, at least 50% of the time it seems to end in disappointment.
A great crab cake (keto or otherwise) should consist of mostly good quality crab meat, and have very little breading holding it together.
When done right, it’s sweet and delicate and absolutely wonderful. When done wrong, it’s a fishy tasting bread puck with barely any discernible crab pieces to be found – a travesty and a crime against seafood.

Enter these delicious keto crab cakes – which are just as good or better then most crab cakes you’ll find in a restaurant…
Because the best (and most economical) way to ensure that you are getting high quality and delicious crab cakes is to make them yourself at home.
These keto crab cakes are so easy to make, that there is really no excuse not to make them yourself when the craving for crab cakes strikes. Which, if you’re like me, is often.
I like to enjoy these keto crab cakes with my creamy keto roasted red pepper sauce. It’s a perfect match in my opinion, but not required if you’re not a fan of the flavor of roasted red peppers.
What kind of crab meat is best for crab cakes?
Typically, blue crab is used for crab cakes. You can find it in the seafood section, usually in 8 ounce plastic cups that are refrigerated. That will taste the best without actually catching the crabs yourself.
You can also get frozen blue crab if you don’t live in an area where fresh crab is readily available – the quality is slightly inferior to fresh, but still good.

When choosing blue crab at the supermarket, there will be several varieties and price points.
Lump crab is the best and most desirable for these keto crab cakes, but also the most expensive option.
Claw meat is cheaper and not as sweet, but will work just fine for this recipe. If you’re doubling it to serve to a crowd, I recommend a 50/50 split between lump and claw meat to keep costs down while still maximizing quality, which is what I usually do.
As an alternative to blue crab, you can use Dungeness, King, or even snow crab in these keto crab cakes and it will be delicious.
Never use canned crab from the tuna fish aisle in crab cakes – it will have terrible texture and flavor.
Ingredients you will need
- Good quality crab meat (see notes above)
- Mayonnaise (I find this holds them together better then eggs)
- Fresh lemon juice (I beg you not the bottled stuff)
- Dijon mustard
- Parsley
- Coconut flour
- Old Bay Seasoning
- Avocado oil for frying

Equipment you will need
A bowl and a nonstick frying pan are really all you need to make this keto crab cakes recipe!
Instructions
- Combine all of the crab cake ingredients in a bowl.
- Mix gently so as not to break up the pieces of crab.
- Form into cakes.
- Fry.
- Serve warm.
Storage Information
Seafood doesn’t keep long leftover, so I recommend not storing these crab cakes for more than three days in the refrigerator. Keep them in an airtight container so your entire fridge doesn’t smell like crab.
Reheat them gently in the microwave for 1 – 2 minutes, or in the oven at 350 degrees Fahrenheit for 8 – 10 minutes just to get them heated all the way through.
I don’t recommend freezing these keto crab cakes, as the texture would not be ideal after thawing and reheating.
Serving Suggestions
- As mentioned above, my favorite way to serve these is with my keto red pepper sauce.
- The recipe makes 4 servings as an appetizer, or 2 servings as a main course.
- For a lunch or brunch portion, these work really well with a simple salad of arugula or spring greens dressed with my keto lemon vinaigrette – and save a splash of the vinaigrette to drizzle over the crab cakes as well.
- If you’re serving these keto crab cakes for a cocktail party or event, you can make the cakes even smaller as a bite-sized portion of about 1-inch in diameter and pass them on a platter with just a dot of sauce on the top. This recipe should make about 24 cakes in miniature.
Variations and Substitutions
- For different crab meat options see the notes above on what type of crab meat to use.
- Dijon mustard contains trace amounts of white wine, if doing the Whole30 or if strictly avoiding alcohol for any other reason, replace the dijon mustard with another yellow mustard. If doing Squeaky Clean Keto, the dijon mustard is acceptable because the amounts of wine are so slight.
- Worcestershire sauce contains small amounts of molasses and sugar, so if doing the Whole30 or Squeaky Clean Keto you can replace it with Coconut Aminos to stay compliant.
- If coconut flour is a problem for you, it can be replaced with almond flour as a binder. Crushed pork rinds can also be used, but may impact the flavor negatively so it should be a last resort.
- The mayonnaise can be replaced with 2 tablespoons of beaten egg, but I prefer the mayonnaise because it holds the crab cakes together better in my opinion.

We made these today for lunch and loved them! I had a pound of crab which meant I ended up tripling the recipe, but it worked great. Mine stayed together really well and were almost like “crab burgers” (we made 7 patties total, so they were large!). Really tasty. Will use your recipe again! Thanks!
Mellissa Sevigny says
Glad you liked these Laura, it’s been awhile since I’ve made them and your comment reminded me of how much I loved them! I’ll have to put them on our menu again soon! :)
Beverly Hoover says
These crab cakes are great. My Husband and I enjoyed them and the roasted red pepper sauce is awesome. Shhh, don’t tell him it was made with avocado. Going to buy you book for my kindle!!
Jenny says
I was so inspired to try these but I’m sad to say that, despite being extra careful handling them in the pan, the cakes completely fell apart. I ended up serving the cake parts over spinach with the sauce as dressing. Not a bad dinner, but I’m bummed. Is there anything I can do to help firm these guys up so they stay together in the pan?
Nicole says
We were talking about dinner tomorrow night and surf n turf came up. Nice alternative for the surf. I look forward to making this. Just started following your site and I am so pleased I found you. You are our food network star. Congrats for getting through and thank you for all your work. Do you also have a recipe book for those people who don’t have computers? Would make a great gift.
Mellissa Sevigny says
Thanks Nicole and welcome to IBIH! I do not have a hard copy cookbook out yet, but hopefully that will happen someday! :) Hope you enjoy the crab cakes – this is one of my favorites!

Lee Kirsten MacKenzie says
These look absolutely delicious. Also, I am hungry right now. I love your writing, recipes, and food photography! WOW! I have really been enjoying this website, and am bragging about you on FB and my blog. Can’t wait to try these. Yeah, coconut flour hasn’t shown up here in Northern Oregon. Although, I am sure I can order it online, or find a better health food store.
Mellissa Sevigny says
Thanks so much Lee! I get my coconut flour online – it’s cheapest that way! Try Nuts.com – they had the best price last time I bought it and they have a lot of other great products as well.

I don’t have any coconut flour. Any substitutions?
Thanks!
Mellissa Sevigny says
You can try almond flour if you have it – you just need something to give it a little crunch on the outside. You could also try ground flax if you have it, or even parmesan cheese but it would definitely alter the flavor a bit.

These look great! And here I thought I’d struck gold after finding 4 net carb crab cakes at the grocery store (at over $8 for a box of TWO!). Thank you!
Debbie says
What is Old Bay seasoning?
Julie says
Debbie, Old Bay seasoning is a spice blend. If you are crazy like me, here’s a link to make your own: http://busycooks.about.com/od/homemademixes/r/oldbaymix.htm. Its a pretty good one; hope that helps!
Mellissa Sevigny says
Thanks for sharing this link Julie! I’m going to try making my own since I think buying it is kind of a ripoff since it’s marked up so high.
