These keto crab cakes are made with almond flour. They are absolutely not a compromise! They are wonderfully crispy and so very flavorful.

These keto crab cakes are amazing. They are delicious and filling. My entire family loves them, so I make them often. They're so good, in fact, that I often serve them as a main course rather than as an appetizer. They don't contain any breadcrumbs. Instead of those, I use almond flour. The result is marvelous - just as good as traditional recipes.

Ingredients

The ingredients needed for keto crab cakes.

See the recipe card for exact measurements. Here are my comments on some of the ingredients.

  • Egg: Make sure it's truly large - you need it to help bind the ingredients together.
  • Fresh lump crabmeat: Although lump meat is perfect for crab cakes, I sometimes use jumbo lump crabmeat when it's the freshest option. It works fine if you break it into smaller pieces, but it's more expensive.
  • Mayo and mustard: You should definitely use Dijon mustard. It's creamier and less vinegary than yellow mustard, and it's way more delicious! Sometimes, I use sriracha mayo for an added kick.
  • Butter and olive oil: Used for frying the cakes. I like to use both - the butter is delicious and the oil helps prevent the butter from browning too much. To make this recipe dairy-free, use extra olive oil instead of butter.

Instructions

The detailed instructions and step-by-step photos are included in the recipe card. Here's a quick overview.

Mix together all the ingredients except for the butter and olive oil. Make sure the mixture is uniform and well-combined. Form the mixture into six patties. Chill the patties in the fridge for at least an hour.

Fry the patties in a mixture of butter and olive oil over medium heat for 4-5 minutes per side.

Recipe Tips

  1. Use fresh crab meat. As always, when using crabmeat in recipes (such as these crab-stuffed mushrooms), the fresher the crabmeat, the better the dish will taste. This is one item I splurge on - I get it fresh at Whole Foods whenever possible.
  2. Chill the patties before cooking. It's important to chill the patties for at least an hour before frying them. They are quite delicate and could easily fall apart when you fry them if they're not chilled first.
  3. Don't skimp on the oil! At least half the cooking fat will remain in the skillet, but it's needed to cook the patties properly. The nutrition info reflects this.
  4. Use a nonstick skillet and don't overcrowd it. If you don't have a skillet large enough to accommodate all patties, fry them in two batches and keep the first batch in an oven set to the "keep warm" setting (usually 170°F).

Recipe FAQs

Can I eat crab cakes on the keto diet?

You can, as long as you replace the traditional breadcrumbs with a low-carb ingredient such as almond flour or crushed pork rinds.

Can I bake these crab cakes?

I like to fry them. It achieves a crispier result. But you can bake them in a 350°F oven on a parchment-lined, rimmed baking sheet for 15 minutes per side. Spray them with oil before baking and spray again after flipping them.

Are they spicy?

No. The small amount of cayenne pepper I use adds a layer of flavor. It doesn't make them spicy. However, feel free to omit the cayenne if you wish.

How long can I keep the leftovers?

You can keep the leftovers in an airtight container in the fridge for up to three days. Reheat them uncovered in a 350°F oven to retain their crispness. If you're in a hurry, it's OK to use the microwave, but the oven is better. They are also good cold, straight out of the fridge! I sometimes grab one as a snack.

You can also freeze the completely cooled leftovers in freezer bags for up to three months. If you stack them, separate the layers with wax paper. Thaw them overnight in the fridge before reheating.

Serving Suggestions

Sauce

If you'd like to serve these crab cakes with a sauce, mix ¼ cup of mayonnaise with 1 tablespoon of Dijon mustard, 1 tablespoon of sugar-free ketchup, and ½ teaspoon of garlic powder. You can also use homemade tartar sauce or sriracha mayo.

Side Dishes

When I serve these crab cakes as a main course rather than as an appetizer, I like to serve them with cauliflower potato salad, creamy cucumber salad, broccoli salad, or asparagus salad. I like the fact that I can make these salads ahead of time so that I can focus on frying the patties.
