These Tuna Patties with Sweet Potato are always a crowd-pleaser! Ready in just 30 minutes, they’re crispy, flavorful, and so delicious! This recipe is perfect as a light meal or a hearty appetizer.
I always love a satisfying recipe that I can make with just a few pantry staples. These tuna patties are made with canned tuna and sweet potatoes, plus a few other simple ingredients. They’re also super versatile, so I can enjoy them as a full meal, a satisfying snack, or a tasty appetizer.
If you have leftovers, they’re perfect for meal prep, too! I like to make a few extras and portion them out for lunches, similar to these Salmon Patties with Coleslaw Meal-Prep Bowls.

Sweet potatoes are such a delicious addition to classic tuna patties! They help hold everything together, so the patties don’t fall apart when you cook them, like most fish cakes. Plus, it makes them soft on the inside, crispy on the outside, and absolutely irresistible.
Ingredients
- Sweet potatoes — I use 2 small sweet potatoes for this recipe.
- Tuna — I recommend using good-quality canned tuna. Feel free to use whatever variety you prefer.
- Onions — For the best flavor, I like a combination of white and green onions.
- Breadcrumbs — I use gluten-free breadcrumbs, but you can use regular if you don’t need the recipe to be gluten-free. Or you can use almond flour too.
- Eggs — The eggs are what bind the ingredients together.
- Seasonings — I use a blend of garlic powder, chili pepper, and salt and pepper.
- Lemon— I juice half of the lemon, and cut the other half into wedges.
- Mayonnaise — I recommend trying my easy homemade mayonnaise for this recipe. Of course, you can use whatever mayo you have on hand.
- Cooking spray — For simplicity’s sake, I like to use olive oil cooking spray, but you can also use a drizzle of olive oil.

Instructions
Cook the sweet potatoes:
- In a medium pan or stockpot, bring water to a boil and add the cubed sweet potatoes. Cook them for about 10 to 15 minutes, or until they’re fork tender.
- Drain the sweet potatoes and run them under cold water to cool them down. Then, transfer them to a large mixing bowl and mash with a fork.

Combine the ingredients:
- Once the sweet potatoes have cooled, add the tuna, green onions, white onions, breadcrumbs, eggs, and mayonnaise. Season with garlic powder, chili pepper, lemon juice, salt, and pepper.
- Then, mix until all the ingredients are well combined.

Shape and cook the patties:
- Using your hands, shape the tuna mixture into evenly sized patties or tuna cakes/tuna burgers.
- Heat a non-stick frying pan over medium heat and add cooking spray, vegetable oil, or olive oil.
- Cook the tuna patties for 3 to 4 minutes on both sides or until they’re golden brown.

Garnish and serve:
- Allow the tuna patties to cool slightly before serving.
- Garnish with chopped scallions or fresh herbs, if desired. Serve with lemon wedges, yogurt for dipping, and enjoy!

Expert Tips
- For perfectly uniformed patties, I use a large ice cream or cookie scoop to portion out the mixture.
- Be sure to chop the sweet potatoes as uniformly as possible so they cook evenly. Alternatively, you can buy pre-cut sweet potatoes in the produce section of your grocery store.
- A great time-saver that I recommend is to place the green onions and onions in a food processor to mince them up super finely.
- My secret to the perfect sear is to not overcrowd the pan or flip the patties too soon. Allow them plenty of space to cook and time to get nice and browned.
- If the patties are hard to form, I suggest letting them chill in the refrigerator for about 10 minutes. You can also wet your hands with cold water to keep the mixture from sticking.

- Flavorful sauce: These tuna patties are incredible on their own, and even better with a yummy sauce. I recommend a simple lemon aioli or this creamy avocado sauce.
- Side salad: When I want a fresh meal that’s still cozy, I like to pair this recipe with delicious side dishes like this roasted sweet potato kale salad or arugula salad.
- Fluffy rice: For a warm, satisfying lunch or dinner, I like to serve these tuna patties on top of fluffy rice, quinoa, or cauliflower rice.
