🐟🌽 Keto Tuna & Corn Fritters

Crispy on the outside, tender and savory inside, these Keto Tuna & Corn Fritters make an easy lunch, dinner, or snack. For a lower-carb version, a small amount of corn is paired with coconut flour, eggs, Parmesan, and tuna instead of regular flour or breadcrumbs. A similar low-carb tuna-corn patty uses tuna, corn, eggs, Parmesan, coconut flour, and seasonings.

🍽️ Servings

3–4 servings | about 8–10 fritters

⏱️ Time

  • Prep: 10 minutes
  • Cook: 15–20 minutes
  • Total: About 25–30 minutes

🛒 Ingredients

  • 2 cans (5 oz/142 g each) tuna, drained very well
  • ½ cup sweet corn, drained
  • 2 large eggs
  • 3 tablespoons coconut flour
  • ¼ cup grated Parmesan cheese
  • 2 tablespoons mayonnaise
  • 2 tablespoons finely diced red onion
  • 2 tablespoons chopped fresh parsley
  • 1 tablespoon lemon juice
  • ½ teaspoon garlic powder
  • ½ teaspoon dried oregano
  • ½ teaspoon salt, or to taste
  • ¼ teaspoon black pepper
  • ¼ teaspoon paprika
  • 1–2 tablespoons olive or avocado oil, for frying

Keto note: Corn contains more carbohydrates than most traditional keto vegetables, so keeping the portion modest makes this recipe lower-carb rather than completely carb-free.

👩‍🍳 Instructions

1. Drain the tuna

Drain the tuna extremely well.

Press out as much liquid as possible, then flake it with a fork.

This is important: watery tuna will make the fritters difficult to shape and more likely to fall apart.

2. Prepare the corn

Drain the corn thoroughly.

Pat it dry with a paper towel if it is particularly wet.

For a very low-carb version, reduce the corn to ¼ cup.

3. Make the mixture

Add the following to a large bowl:

  • Tuna
  • Corn
  • Eggs
  • Coconut flour
  • Parmesan
  • Mayonnaise
  • Red onion
  • Parsley
  • Lemon juice
  • Garlic powder
  • Oregano
  • Paprika
  • Salt
  • Black pepper

Mix thoroughly until everything is evenly combined.

4. Let it rest

Allow the mixture to sit for 3–5 minutes.

The coconut flour will absorb some moisture and help the mixture become firm enough to shape.

If the mixture still seems too wet, add 1 teaspoon coconut flour at a time.

5. Shape the fritters

Scoop approximately 2–3 tablespoons of mixture into your hands.

Form into a round patty about ½-inch thick.

Repeat until all the mixture is used.

You should get approximately 8–10 fritters.

6. Heat the pan

Heat 1–2 tablespoons of olive or avocado oil in a large nonstick skillet over medium heat.

The oil should be hot but not smoking.

7. Cook the fritters

Carefully place the patties into the pan, leaving a little space between them.

Cook for approximately 4–5 minutes on the first side.

Don’t move them around too much while they cook—the bottom needs time to develop a firm golden crust.

8. Flip carefully

Once the underside is deep golden brown and firm, gently flip each fritter with a thin spatula.

Cook the second side for another 3–4 minutes.

They should be crisp and golden on both sides.

Low-carb tuna fritters are commonly cooked over medium-low heat for several minutes per side until golden and cooked through.

9. Drain

Transfer the cooked fritters to a plate lined with paper towels.

Let them rest for 2 minutes before serving.

🥑 Quick Keto Dipping Sauce

Mix together:

  • ½ cup mayonnaise
  • 1 tablespoon lemon juice
  • 1 tablespoon chopped parsley
  • ¼ teaspoon garlic powder
  • Pinch of salt
  • Black pepper to taste

For a spicy version, add a few drops of hot sauce.

🔥 Air Fryer Method

You can also make these without pan-frying.

  1. Preheat air fryer to 375°F (190°C).
  2. Lightly spray the basket with oil.
  3. Place the patties in a single layer.
  4. Spray the tops lightly with oil.
  5. Air fry for 8–10 minutes.
  6. Carefully flip halfway through.
  7. Continue until golden and crisp.

Air-fryer tuna patties are commonly cooked around 360°F for roughly 8–10 minutes with a flip halfway through.

⭐ Tips for Perfect Fritters

  • Drain tuna very well—this is the biggest secret to firm fritters.
  • Don’t make the patties too thick.
  • Let the mixture rest before shaping.
  • Cook over medium heat, not high heat.
  • Wait until the first side is well browned before flipping.
  • Use a thin spatula for an easier flip.
  • If your mixture is too soft, add a little more coconut flour.
  • If it’s too dry, add 1 tablespoon mayonnaise.
