These salmon cakes bring bright lime, creamy avocado, and crispy seared edges together in a way that feels fresh but totally comforting.

Ingredients
Method
- Prep the salmon: If using canned salmon, drain well and flake with a fork, removing any large bones or skin if preferred. If using cooked salmon, let it cool and flake into small pieces.
- Mix the base: In a large bowl, whisk eggs, mayonnaise, lime zest, lime juice, cumin, smoked paprika, garlic, salt, and pepper until smooth.
- Add the flavor: Stir in cilantro and green onion. Fold in the salmon and almond flour until evenly combined.
- Gently add avocado: Fold in the diced avocado last to keep chunks intact. The mixture should be moist but able to hold together when pressed. If it’s too loose, sprinkle in a bit more almond flour, 1 tablespoon at a time.
- Form patties: With damp hands, shape into 8 small patties (about 2.5–3 inches wide) or 4 larger patties. Press them firmly so they don’t crumble.
- Chill (optional but helpful): Place patties on a plate and chill for 15–20 minutes. This makes them easier to flip cleanly.
- Heat the pan: Warm a large skillet over medium heat. Add 2 tablespoons avocado oil and let it shimmer.
- Cook the cakes: Add patties to the pan without crowding. Cook 3–4 minutes per side for small cakes (4–5 minutes for larger), until golden brown with crisp edges. Add more oil as needed for the next batch.
- Finish and serve: Squeeze a little fresh lime over the cakes. Serve with the quick lime mayo, extra cilantro, and lime wedges.
What Makes This Recipe So Good
These salmon cakes hit that sweet spot of being both light and filling. The lime and cilantro keep everything fresh, while the avocado brings rich creaminess without dairy. They’re easy to pan-sear and made with pantry staples.
You can use canned or cooked fresh salmon, and the cakes hold together beautifully without breadcrumbs. Each bite balances citrus, herbs, and savory salmon, all while staying low in carbs and high in healthy fats.

Keeping It Fresh
These salmon cakes keep well for a couple of days, which makes them great for meal prep. Store in an airtight container in the fridge for up to 3 days.
Reheat in a skillet over medium heat with a touch of oil to bring back the crisp edges, or air-fry at 375°F for 4–5 minutes. You can also freeze cooked cakes on a sheet pan, then transfer to a freezer bag for up to 2 months. Thaw overnight in the fridge before reheating.
Health Benefits
- Omega-3 fats: Salmon is rich in EPA and DHA, which support heart health, brain function, and help calm inflammation.
- Keto-friendly fats: Avocado and avocado oil add monounsaturated fats that help keep you satisfied without spiking blood sugar.
- Protein-rich: Salmon and eggs offer a solid protein boost to support muscle repair and steady energy.
- Low carb: Almond flour replaces breadcrumbs, keeping net carbs low while adding fiber and vitamin E.
- Micronutrients: Lime brings vitamin C; herbs and green onions add antioxidants and fresh flavor without extra calories.
Pitfalls to Watch Out For
- Too wet a mixture: If your cakes won’t hold shape, add a little more almond flour or let the mixture chill longer.
- Overmixing avocado: Stir gently so the avocado stays in pieces.
Overmixing turns it mushy and changes texture.
- High heat burning: Keep heat at medium to medium-high. Too hot and the outside burns before the center sets.
- Skipping salt: Salmon needs adequate seasoning. Taste the mixture (a small cooked test patty works) and adjust.
- Old oil: Use fresh, high-heat oil for crisp edges and clean flavor.
Rancid oil ruins the dish.
Alternatives
- No almond flour: Use finely ground pork rinds or coconut flour. If using coconut flour, start with 1–2 tablespoons; it’s very absorbent.
- No cilantro: Swap with parsley or dill. Dill pairs especially well with salmon and lime.
- Spice boost: Add a pinch of cayenne or minced jalapeño to the mix for gentle heat.
- Dairy-free sauce: Use avocado mashed with lime, salt, and a splash of olive oil instead of mayo.
- Bake instead of pan-sear: Brush patties with oil and bake at 400°F for 12–15 minutes, flipping once, then broil 1–2 minutes for color.
- Use fresh herbs you have: Chives, basil, or mint can add a fun twist while staying light and fresh.
FAQ
Can I use fresh salmon instead of canned?
Yes.
Flake cooked, cooled salmon and use the same amount by weight. Make sure it’s not too wet; pat with paper towels if needed so the cakes hold together.
How do I keep the cakes from falling apart?
Use the right balance of binders and moisture. Press patties firmly, chill them, and cook over medium heat.
If the mixture is loose, add a bit more almond flour or a third egg white.
Is this recipe spicy?
Not by default. It’s bright and zesty. If you want heat, add cayenne, jalapeño, or a few red pepper flakes to the mix or the sauce.
Can I make them ahead?
Yes.
Form the patties and refrigerate up to 24 hours before cooking. Or cook them, cool completely, and store for up to 3 days. Reheat in a skillet or air fryer for best texture.
What can I serve with these salmon cakes?
They’re great with a crunchy slaw, mixed greens with a lime vinaigrette, grilled asparagus, or sautéed zucchini.
A few avocado slices and extra lime wedges round it out nicely.
Are they gluten-free?
Yes, as written. Almond flour replaces breadcrumbs, and there’s no wheat. Always check your mayo and spices for hidden gluten if you’re sensitive.
Can I omit the mayo?
You can.
Replace it with 1–2 tablespoons of mashed avocado or a little olive oil to keep the mixture moist. The texture will still be tender.
What oil is best for cooking?
Avocado oil handles higher heat and keeps flavors clean. Light olive oil also works well.
Avoid butter for searing, as it can burn quickly.
