Easy Tuna Keto Fish Cakes

These delicious, soft, and low-carb keto fish cakes are made with canned tuna, an ideal healthy lunch option, or light dinner paired with greens or a salad.

Easy keto fish cakes with canned tuna

Canned tuna is a hugely versatile ingredient, but sadly so many of us either ignore it, or simply empty the can into salads, or mix with mayo for snadwiches. But it can be so much more!

These patties are super simple to make with ingredients you already have in your pantry and are family-friendly. They are a great way to add more fish into your diet and the kids will love them too.

A simple mix of canned tuna, mayo, almond flour, eggs, and seasoning produce scrumptious tuna patties.

The tuna patties can be served with almost anything. Use them in a keto burger bun, serve with mashed cauliflower, or with simple yet effective garlic aioli. I usually eat these with some wilted, buttered greens with a little lemon juice, and an avocado salad for a filling, healthy lunch.

To make a garlic aioli to go with these, simply blend 1/4-1/2 cup of quality mayonnaise with 1-2 cloves garlic and 2 tbsp lemon juice. This is a great, simple condiment that perfectly compliments these fish cakes (along with a million other things!).

If you want a Mediterranean touch, serve tuna patties on top of arugula or mixed greens salad, topped with some drained capers. The possibilities are endless and let your imagination guide you. Here are some suggestions to get you started:

Easy Ways to Customise Your Keto Fish Cakes:

  • Asian Keto Fish Cakes: Try adding in some grated ginger, garlic, chilli and cilantro, some lime zest, and sprinkle a little lime juice on top after cooking
  • Indian Spiced Keto Fish Cakes: Add some spices into the mix, try some turmeric, cumin, garam masala along with grated garlic and ginger, serve with a little yoghurt mixed with mint and cucumber
  • Middle Eastern Style Keto Fish Cakes: Add ground cumin and paprike, chopped cilantro and parsley, some grated carlic; serve with a tahini dipping sauce made up of tahini, garlic, lemon juice and salt.
