- Meal-prep friendly: The patties reheat well and stay moist, making them perfect for lunches and snacks.
- Customizable: You can swap herbs, add spice, or change the cheese without losing the core recipe.
Storage Instructions
- Refrigerator: Store cooled patties in an airtight container for 3–4 days. Separate layers with parchment to prevent sticking.
- Freezer: Freeze on a sheet pan until solid, then transfer to a freezer bag for up to 2 months.
Label with date.
- Reheat: Air fry at 350°F (177°C) for 4–6 minutes from the fridge, or 8–10 minutes from frozen. You can also reheat in a skillet with a little oil.
Benefits of This Recipe
- Keto-friendly: Low in carbs, high in protein and healthy fats to support satiety and steady energy.
- Budget-wise: Canned tuna is affordable and lasts in the pantry, making this a cost-effective meal.
- Fast and easy: Minimal chopping, one bowl, and quick air fryer time.
- Portable: Great for meal prep, lunch boxes, or post-workout snacks.
- Nutrient-dense: Tuna provides protein and omega-3s, while eggs and almond flour add texture and healthy fats.
Common Mistakes to Avoid
- Not draining the tuna: Excess moisture makes patties fall apart. Press it dry with paper towels if needed.
- Skipping the preheat: A cold air fryer leads to soggy, pale patties.
Always preheat for best browning.
- Overmixing: This can make the patties dense. Fold gently and keep some tuna flakes intact.
- Overcrowding the basket: Air needs space to circulate. Cook in batches for even crisping.
- Flipping too early: Let the bottom set and brown before turning or the patties may break.
Variations You Can Try
- Spicy jalapeño: Add minced jalapeño, a pinch of cayenne, and swap paprika for chipotle powder.
- Dill and caper: Stir in chopped dill and a few drained capers for a briny, fresh profile.
- Cheddar and chive: Replace Parmesan with sharp cheddar and use chives instead of parsley.
- Asian-inspired: Add a splash of coconut aminos, grated ginger, and a few drops of sesame oil.
Serve with a sugar-free sriracha mayo.
- Zesty lemon-pepper: Double the lemon zest and use lemon-pepper seasoning in place of black pepper.
- Sardine swap: For more omega-3s, replace half the tuna with boneless, skinless sardines. Mash well for a smoother texture.
Keto Air Fryer Tuna Patties – Crispy, Easy, and Low-Carb
Ingredients
- 2 cans (5 oz each) tuna in water, drained well
- 2 large eggs
- 1/3 cup almond flour (fine or superfine)
- 2 tablespoons mayonnaise (sugar-free)
- 2 tablespoons grated Parmesan (adds umami and helps crisp)
- 2 tablespoons finely chopped red onion (or green onion)

Instructions
- Preheat the air fryer: Set it to 380°F (193°C) for about 3 minutes so it’s hot when the patties go in.
- Prep the tuna: Drain the cans thoroughly and press out excess liquid.Drier tuna makes sturdier, crispier patties.

- Add the dry ingredients: Stir in almond flour and Parmesan until just combined.
- Fold in tuna and aromatics: Add tuna, onion, and parsley. Gently mix to keep some texture. The mixture should be moist but hold together.
- Adjust consistency if needed: If it’s too wet, add 1 tablespoon of almond flour at a time.If too dry, stir in 1 teaspoon of mayo or a splash of lemon juice.
- Form the patties: Scoop about 1/4 cup of mixture per patty. Shape into 8 small patties about 1/2 inch thick.
- Prep the basket: Lightly spray the air fryer basket with oil to prevent sticking.
- Air fry batch one: Place patties in a single layer without crowding. Spray the tops lightly.Cook for 8–10 minutes, flipping halfway, until golden and firm.
- Repeat with remaining patties: Keep the first batch warm while the rest cook. Add a quick spritz of oil between batches if needed.
- Serve: Squeeze fresh lemon over the patties and serve with a simple aioli, sugar-free tartar sauce, or a creamy avocado dip.
FAQ
Can I bake these instead of using an air fryer?
Yes. Bake at 400°F (204°C) on a parchment-lined sheet, lightly oiled, for 12–15 minutes, flipping once.
They won’t be quite as crisp as air fried, but they’ll still brown nicely.
What can I use instead of almond flour?
Finely ground pork rinds or coconut flour both work. If using coconut flour, start with 1 to 2 tablespoons since it absorbs more moisture.
How do I keep the patties from falling apart?
Make sure the tuna is well-drained, the mixture is not overly wet, and the patties are compressed firmly. Let them cook long enough on the first side to set before flipping.
Is canned tuna in oil okay for this recipe?
It’s fine, but drain it especially well to prevent greasy patties.
If using oil-packed tuna, you may need slightly less mayonnaise.
What sauces are keto-friendly to serve with these?
Try lemon-garlic aioli, sugar-free tartar sauce, sriracha mayo (with no-sugar-added sriracha), or a yogurt-based herb dip made with full-fat Greek yogurt.
Can I make them dairy-free?
Yes. Omit the Parmesan and add an extra tablespoon of almond flour for structure. Check your mayonnaise to ensure it’s dairy-free.
Do I need to chill the mixture before cooking?
Not required, but chilling for 15–20 minutes can make shaping easier and reduce breakage if your mixture feels loose.
What should I serve with these patties?
They’re great with a crisp salad, roasted asparagus, cauliflower rice, or in lettuce wraps with sliced avocado and tomato.
How many patties is a serving?
Typically 2 patties per person, depending on size and what you serve alongside them.
Can I use fresh tuna?
You can, but it needs to be cooked and flaked first.
Canned tuna offers better binding and texture for this style of patty.
