Air Fryer Keto Tuna Patties - Crispy, Fast, and Low-Carb
Ingredients
- Canned tuna: 2 cans (5 ounces each), drained well; water-packed or oil-packed both work.
- Egg: 1 large, for binding.
- Almond flour: About 1/3 cup, finely ground.
- Mayonnaise: 2 tablespoons, for moisture and richness.
- Dijon mustard: 1 teaspoon, for a subtle tang.
- Green onion or chives: 2 tablespoons, finely sliced.
- Fresh parsley: 2 tablespoons, chopped (optional but brightens flavor).
- Garlic powder: 1/2 teaspoon.
- Onion powder: 1/2 teaspoon.
- Paprika or smoked paprika: 1/2 teaspoon.
- Lemon zest: 1/2 teaspoon, plus lemon wedges for serving.
- Salt and black pepper: To taste.
- Olive oil or avocado oil spray: For the air fryer basket and patties.
- Optional add-ins: 1 tablespoon capers (chopped), a pinch of red pepper flakes, or 2 tablespoons finely diced celery for crunch.
Instructions
- Preheat the air fryer: Set it to 380°F (193°C) for 5 minutes so it’s hot and ready.
- Prep the tuna: Drain the cans thoroughly and press out extra liquid with the lid. The drier the tuna, the better your patties hold together.
- Mix the base: In a bowl, combine tuna, egg, almond flour, mayonnaise, and Dijon. Stir until the mixture looks evenly moistened but not wet.
- Season well: Add green onion, parsley, garlic powder, onion powder, paprika, lemon zest, salt, and pepper. Mix gently. If it feels loose, add 1–2 teaspoons more almond flour.
- Shape the patties: Divide the mixture into 6–8 small patties, about 1/2 inch thick. Compact them with your hands so they hold together.
- Spray for crispness: Lightly spritz both the patties and the air fryer basket with oil. This helps with browning and prevents sticking.
- Air fry the first side: Arrange patties in a single layer with space between. Cook at 380°F (193°C) for 7–8 minutes until set and lightly golden.
- Flip and finish: Carefully flip, spray the tops again, and cook another 4–6 minutes until crisp and nicely browned.
- Check doneness: Patties should be firm, heated through, and golden on both sides. Adjust time slightly based on your air fryer model.
- Serve: Squeeze fresh lemon over the top and serve with a keto-friendly dip like garlic aioli, spicy mayo, or tartar sauce. Great with a side salad or roasted veggies.

Health Benefits
- High-quality protein: Tuna supports muscle repair and keeps you satisfied, which can help with appetite control on keto.
- Healthy fats: Mayo and olive or avocado oil add fats that align with keto goals and boost flavor.
- Omega-3s: Tuna provides heart-friendly omega-3 fatty acids that support brain and cardiovascular health.
- Low-carb binders: Almond flour replaces breadcrumbs, keeping net carbs down while adding vitamin E and magnesium.
- Air frying advantage: You get a crispy finish with much less oil than deep-frying.
Common Mistakes to Avoid
- Skipping the drain: Excess moisture makes patties fall apart. Drain tuna very well.
- Overmixing: Stir just until combined.
Overworking can make patties dense.
- Patties too thick: Thick patties may brown outside but stay soft inside. Aim for about 1/2 inch.
- Overcrowding the basket: Give space for airflow or they won’t crisp properly.
- Under-seasoning: Tuna needs bold seasoning. Taste the mixture (before adding egg if you prefer) and adjust.
Alternatives
- Different binders: Swap almond flour with crushed pork rinds for extra crunch, or use coconut flour (start with 1–2 tablespoons; it absorbs more moisture).
- Protein swaps: Use canned salmon or cooked, flaked chicken in place of tuna.
Adjust seasoning to taste.
- Dairy add-ins: Fold in 1/4 cup shredded Parmesan or cheddar for a richer flavor and extra crisp edges.
- Flavor twists: Try Cajun seasoning, curry powder with cilantro, or lemon-pepper with dill. A little hot sauce in the mix adds gentle heat.
- Sauce ideas: Mix mayo with lemon juice and garlic, or stir together Greek yogurt (if it fits your carbs) with dill and capers.
FAQ
Can I make these without eggs?
Yes. Replace the egg with 1 tablespoon mayonnaise plus 1–2 teaspoons ground flaxseed.
Let the mixture rest 5 minutes so it binds. The texture will be slightly softer but still holds.
Do I have to use almond flour?
No. Crushed pork rinds work well and keep carbs very low.
Coconut flour is also an option, but use less and add slowly because it absorbs more moisture.
Why are my patties falling apart?
They’re likely too wet or too thick. Drain tuna thoroughly, press the mixture firmly when shaping, and add a bit more almond flour if needed. Also, flip gently and let them set during the first few minutes of cooking.
Can I pan-fry instead of air fry?
Absolutely.
Heat a thin layer of oil in a nonstick skillet over medium heat and cook 3–4 minutes per side until golden. Keep the patties small and compact for easier flipping.
What’s a good side dish?
Try a crunchy cabbage slaw with lemon, a simple arugula salad, roasted asparagus, or cauliflower mash. For a handheld option, serve in lettuce wraps with sliced avocado.
Are these kid-friendly?
Yes.
Skip the red pepper flakes and serve with ketchup or a milder dip. Make smaller patties for easy, bite-size portions.
How many carbs are in a serving?
Exact numbers vary by brand, but each patty typically lands around 1–2 net carbs when made with almond flour and standard mayo. Check your ingredient labels for accuracy.
Can I use fresh tuna?
You can, but it’s not necessary.
If using cooked, flaked fresh tuna, make sure it’s cooled and flaky, and season a bit more since fresh tuna can taste milder than canned.
What air fryer temperature works best?
380°F (193°C) is a sweet spot for browning without drying them out. If your air fryer runs hot, drop to 370°F and add 1–2 minutes to the time.
Can I prep the mixture ahead?
Yes. Mix and refrigerate for up to 24 hours.
Shape just before cooking. If the mixture tightens up in the fridge, loosen with a teaspoon of mayo.
