Air Fryer Keto Tuna Patties - Crispy, Fast, and Low-Carb

Prep Time10 minutes
Cook Time12 minutes
Total Time22 minutes
Servings: 4 servings

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.
