Ingredients & smart substitutions

For the salmon cakes

2 cans (6 oz/170 g each) wild-caught salmon, well drained
2 large eggs
1/3 cup superfine almond flour (or see swaps below)
2 tbsp finely chopped green onion or chives
1 tbsp avocado oil mayo (optional for extra moisture)
1 tsp Dijon or stone-ground mustard
1 tsp lemon or lime zest
1/2 tsp garlic powder
1/2 tsp smoked paprika (or regular paprika)
1/2 tsp fine sea salt, plus black pepper to taste
Avocado oil or olive oil for pan-searing (about 2 tbsp)

For the avocado-lime slaw

4 cups finely shredded green or purple cabbage
1 ripe avocado, diced
1/4 cup cilantro, chopped (optional)
2 tbsp avocado oil mayo, or 1–2 tbsp avocado oil
2–3 tbsp fresh lime juice (plus extra to taste)
1/2 tsp fine sea salt, plus pepper to taste
Pinch of cumin or chili powder (optional)

Nut-free and egg-free swaps

Nut-free binder: replace almond flour with 1/3 cup pork panko (crushed pork rinds) or 1/3 cup sunflower seed meal. For coconut flour, use only 1–2 tbsp and let the mixture hydrate 5 minutes before shaping.
Egg-free option: mix 1 tbsp finely ground chia or flax with 3 tbsp water (let gel 5 minutes) to replace 1 egg; for 2 eggs, use 2 chia/flax “eggs.” For extra binding, add 1 tsp psyllium husk or 1 more tbsp mayo. Pan-frying or air frying works best for egg-free patties.

Step-by-step: pan-seared method

Prep the salmon: Drain well and flake salmon in a large bowl, removing any large bone or skin pieces if desired (they’re edible and add minerals).
Mix: Add eggs, almond flour, green onion, mayo, mustard, zest, garlic powder, paprika, salt, and pepper. Stir until the mixture just holds together. It should be moist but not wet. If it’s too loose, sprinkle in another 1–2 tbsp almond flour or pork panko.
Shape: With damp hands, form 8 small patties (about 2.5–3 inches wide) or 6 larger patties. Press gently to compact.
Chill (optional but recommended): Refrigerate patties 10–15 minutes to help them set and crisp.
Preheat the pan: Heat a large skillet over medium to medium-high heat. Add enough avocado oil to thinly coat the bottom.
Sear: Place patties in the hot oil without crowding. Cook 3–4 minutes per side, until deeply golden and crispy. Reduce heat if they brown too quickly before the center sets.
Make the slaw: While the cakes cook, toss cabbage, avocado, cilantro, mayo or oil, lime juice, salt, pepper, and optional spices. Taste and adjust lime and salt. For meal prep, add avocado just before serving.
Serve: Plate salmon cakes hot with a generous pile of avocado-lime slaw and extra lime wedges.

Oven and air-fryer directions

Baked salmon cakes

Preheat oven to 400°F (205°C). Line a baking sheet with parchment and lightly brush or spray with oil.
Arrange patties on the sheet and mist tops with oil. Bake 12–15 minutes, flipping halfway, until edges are golden and centers are set.
For extra crisp: broil 1–2 minutes at the end, watching closely.

Air-fryer salmon cakes

Preheat air fryer to 390°F (200°C) for 3 minutes. Lightly oil the basket or use parchment made for air fryers.
Air fry patties in a single layer 8–10 minutes, flipping at 6 minutes, until browned and crisp. Time may vary by model; thinner patties cook faster.
Tip: A quick spritz of oil gives the crunch you get from pan-searing with less fat and fewer calories.

Keep carbs low without dairy + flavor upgrades

Use almond flour, pork panko, or sunflower seed meal instead of breadcrumbs; they’re keto, paleo, and gluten-free.
Skip sweeteners in the slaw; lime and avocado bring creaminess and brightness without added sugar.
Choose avocado oil mayo with no added sugar to keep carbs minimal and the recipe dairy-free.
Boost flavor with fresh herbs (dill, parsley, cilantro), smoked paprika, or a pinch of red pepper flakes.
For a tangy dip, stir together mayo, lime juice, and a dash of hot sauce—still dairy-free and keto.

Make-ahead, freezer & meal prep tips

Form-ahead: Mix and shape patties up to 24 hours in advance; cover and refrigerate.
Freezer-friendly: Place uncooked patties on a parchment-lined sheet and freeze solid, then transfer to a freezer bag for up to 2 months. Cook from frozen in the air fryer at 380–390°F (193–200°C) for 10–12 minutes, flipping once, or bake at 400°F (205°C) for 15–18 minutes. Pan-searing works best after a brief thaw (10–15 minutes at room temp).
Reheat leftovers: Air fry 3–4 minutes at 360°F (182°C) or warm in a skillet over medium heat 2–3 minutes per side. Avoid the microwave if you want to keep the crust crisp.
Slaw storage: Cabbage stays crisp for 2–3 days. For best color, add avocado just before serving or toss it in extra lime juice to slow browning.
Lunch bowls: Pack two cakes with slaw, lime wedge, and a handful of leafy greens for an easy low-carb meal prep.

Macros, serving ideas & budget notes

Macro estimates will vary based on brand and size, but here’s a solid starting point for four servings (two cakes plus slaw):

Per serving (2 cakes + slaw): about 450 calories, 33 g fat, 27 g protein, 9 g total carbs, 4.5 g fiber, 4.5 g net carbs.

Serving ideas:

Plate with quick pickled onions (use a keto-friendly sweetener if needed), sliced radish, and extra lime.
Add a drizzle of chili-lime mayo or a dairy-free tartar (mayo + dill pickle + lemon).
For extra fat on strict keto days, top with sliced avocado or a spoonful of olive tapenade.

Budget notes:

Canned salmon is significantly cheaper than fresh fillets and still rich in omega-3s.
Cabbage is a low-cost, high-volume keto vegetable that keeps well.
Almond flour is used sparingly; pork panko or sunflower seed meal can cut costs further.
