They’re also a handy way to use pantry salmon and a few simple keto staples. If you like spicy, satisfying food that still keeps you on track, this is your recipe.
Ingredients
Method
- Prep the salmon: Drain canned salmon well. Remove large bones and skin if you prefer a smoother texture, or leave them for extra calcium. Flake into a large bowl.
- Mix the binders: Add eggs, mayonnaise, Dijon, and lemon zest to the bowl. Stir until the mixture is smooth and glossy.
- Add the dry ingredients: Fold in almond flour, Cajun seasoning, smoked paprika, garlic powder, onion powder, salt, and pepper. Adjust seasoning to taste.
- Stir in the crunch: Add green onion, celery, and parsley. If you want extra heat, mix in cayenne or hot sauce.
- Form the patties: With damp hands, shape the mixture into 8 small patties or 6 larger ones, about 3/4-inch thick. Place on a parchment-lined plate.
- Chill: Refrigerate the patties for 15–20 minutes. This helps them set and sear cleanly.
- Heat the pan: Warm a large skillet over medium to medium-high heat. Add avocado oil or ghee and let it shimmer.
- Sear: Place patties in the pan without crowding. Cook 3–4 minutes per side until deep golden and crisp. Reduce heat if they brown too fast.
- Rest: Transfer to a paper towel–lined plate. Squeeze with lemon and sprinkle a pinch of salt while hot.
- Serve: Pair with a quick Cajun mayo dip or a simple arugula salad with lemon and olive oil.
What Makes This Special
These salmon cakes skip the breadcrumbs and use almond flour and egg to hold everything together, keeping it low-carb. The Cajun spice blend adds a smoky, spicy kick without any sugar.
A quick sear in a hot pan gives you that golden crust you crave. Plus, the patties are meal-prep friendly and freeze well, so you can have a flavorful, protein-packed meal ready anytime.

Storage Instructions
- Fridge: Store cooked cakes in an airtight container for up to 3 days. Reheat in a skillet over medium heat or in the oven at 350°F until warmed through.
- Freezer: Freeze cooked patties on a sheet pan until solid, then move to a freezer bag. Keep up to 2 months.
Reheat from frozen in a 375°F oven for 12–15 minutes.
- Meal prep: Mix and shape raw patties, then chill up to 24 hours before cooking. For longer storage, freeze raw patties and thaw in the fridge overnight before searing.
Why This is Good for You
- Omega-3 fats: Salmon is rich in EPA and DHA, which support heart, brain, and joint health.
- High-protein: Each cake delivers solid protein that helps keep you full and supports lean muscle.
- Low-carb, keto-friendly: Almond flour replaces breadcrumbs, keeping carbs minimal and fiber higher.
- Anti-inflammatory spices: Paprika, garlic, and herbs bring antioxidants and flavor without extra calories.
What Not to Do
- Don’t skip chilling: Warm, freshly mixed patties can fall apart in the pan. A quick chill makes a big difference.
- Don’t crank the heat too high: You’ll burn the outside before the center warms through.
Medium to medium-high is your sweet spot.
- Don’t overload with almond flour: Too much makes the cakes dense and dry. Stick close to the listed amount.
- Don’t use sugary sauces: Many store-bought sauces add hidden carbs. Keep the dip simple and clean.
Recipe Variations
- Air fryer version: Spray patties lightly with oil and air fry at 390°F for 8–10 minutes, flipping halfway, until golden.
- Coconut flour swap: Use 2–3 tablespoons coconut flour in place of 1/2 cup almond flour.
Coconut flour is more absorbent, so use less and add as needed.
- Fresh herb lift: Add dill or cilantro for a brighter, garden-fresh note alongside the Cajun heat.
- Dairy-friendly twist: Mix in 1/4 cup finely grated Parmesan for extra umami and crisp edges.
- Milder option: Halve the Cajun seasoning and skip the cayenne. Add a squeeze of lemon and extra parsley to balance flavor.
- Green veggie boost: Fold in finely chopped spinach or kale for extra nutrients without changing texture.
FAQ
Can I use fresh salmon instead of canned?
Yes. Cook and flake about 1 pound of fresh salmon.
Make sure it’s cooled before mixing so the eggs don’t start to cook. The flavor is a little cleaner and the texture slightly chunkier.
How do I keep the cakes from falling apart?
Chill the patties, don’t overcrowd the pan, and let the first side brown fully before flipping. If your mixture is very wet, add 1–2 tablespoons more almond flour, a little at a time.
Is Cajun seasoning keto?
Most Cajun blends are keto, but some brands sneak in sugar or extra starch.
Choose a salt-free, sugar-free blend or make your own with paprika, cayenne, garlic powder, onion powder, thyme, and oregano.
Can I bake these instead of frying?
Yes. Brush with oil and bake at 400°F on a parchment-lined sheet for 12–15 minutes, flipping once. You’ll get a lighter crust than pan-searing, but they still turn out tasty.
What sauce pairs well with these?
A quick Cajun mayo, lemon-garlic aioli, or a sugar-free remoulade works great.
Keep it tangy and creamy to balance the heat.
What sides should I serve?
Try a simple arugula salad, roasted asparagus, sautéed green beans, or a crunchy cabbage slaw with lemon and olive oil. Keep sides fresh and light to let the salmon shine.
Can I make them egg-free?
You can try 2 tablespoons of mayo plus 1 tablespoon ground flax mixed with 2 tablespoons water. The texture won’t be exactly the same, but it will help bind the mixture.
How spicy are these?
They’re medium-spicy as written.
For less heat, use mild paprika, reduce the Cajun blend, and skip cayenne. For more heat, add extra cayenne or hot sauce.
