How to Make Keto Tuna Cakes
-
Drain Tuna: Begin by draining the canned tuna thoroughly. This step is key; excess water can lead to soggy cakes. Place the drained tuna in a large mixing bowl.
-
Chop & Add: Finely dice half of an onion and, if you’re using fresh parsley, chop it as well. Add both the onion and parsley to your mixing bowl with the tuna.
-
Mix Ingredients: Crack in the eggs, then sprinkle in the cheese, mayo, salt, garlic powder, and black pepper. Combine everything gently until mixed well—try not to overwork the tuna for the best texture!
-
Cook: Heat a non-stick pan over medium heat and add a touch of oil to prevent sticking. Spoon the mixture into the pan to form cakes. Cook for about 3 minutes on one side until golden brown, then carefully flip and cook the other side until done.
-
Remove & Cool: Once both sides are a beautiful golden color, remove them from the pan. They’re delicious served warm, but letting them cool slightly can help enhance the flavors.
-
Prepare Lemon Aioli: In a separate bowl, mix together the mayo, minced garlic, parsley, salt, and black pepper. This creamy aioli will elevate your tuna cakes!
-
Add Zest & Juice: Zest the lemon directly into the mixture, and then squeeze its juice over everything while making sure to remove any seeds. Mix thoroughly until well combined. Serve immediately!
Optional: Serve the cakes with fresh lemon wedges for an extra zing.

Expert Tips for Keto Tuna Cakes
-
Drain Well: Ensure that your tuna is thoroughly drained to avoid soggy cakes. Excess moisture can ruin the texture of your Keto Tuna Cakes.
-
Cheese Choice: Opt for a cheese that melts well, like cheddar or mozzarella, to achieve a gooey center that complements the crispy exterior.
-
Don’t Overmix: Combine the ingredients gently; overmixing can make the cakes tough. Treat the tuna with care for that perfect flaky texture.
-
Heat Control: Cook on medium heat to prevent burning. If the pan is too hot, the outside may brown before the inside is cooked through.
-
Aioli Upgrades: For an extra kick in your lemon aioli, try adding a pinch of smoked paprika or a dash of hot sauce to elevate the flavor even more.
-
Serving Tips: Serve your Keto Tuna Cakes with a side of fresh greens or a light salad for a balanced meal that’s both satisfying and nutritious.

Keto Tuna Cakes Recipe FAQs
How do I choose the right tuna for Keto Tuna Cakes?
Absolutely! When selecting canned tuna, look for chunk light tuna packed in water. It’s more affordable and has a milder flavor compared to solid white albacore tuna. Just ensure it’s packed in pure water, as it helps keep the cakes from getting too oily.
How do I store leftover Keto Tuna Cakes?
Leftover Keto Tuna Cakes can be stored in an airtight container in the refrigerator for up to 3 days. Just be sure to cool them completely before sealing; this prevents moisture buildup, keeping them crispy.
Can I freeze Keto Tuna Cakes?
Very! To freeze, place the prepared cakes on a baking sheet in a single layer and freeze until solid, about 1-2 hours. Then, transfer them to a freezer-safe container or zip-top freezer bag. They’ll stay fresh for up to 2 months.
What is the best way to reheat frozen Keto Tuna Cakes?
For the best results, preheat your oven to 375°F (190°C) and arrange the frozen cakes on a baking sheet. Bake for about 10-15 minutes or until heated through. Alternatively, sauté them on medium heat in a skillet, turning occasionally to restore their crunch.
Are there any dietary considerations for Keto Tuna Cakes?
If you’re concerned about allergies, keep in mind that the main ingredients are tuna, eggs, and dairy. If someone is sensitive to shellfish or has a seafood allergy, it’s best to avoid this recipe. For a dairy-free alternative, you can substitute the cheese with a non-dairy cheese or omit it entirely. Remember to adjust seasonings accordingly!
What should I do if my Keto Tuna Cakes are too crumbly?
If your cakes turn out too crumbly, it may be due to insufficient binding. Ensure you’re using fresh eggs, and if additional binding is needed, consider adding a tablespoon of coconut flour or almond flour to the mixture to help hold them together better.
