These low carb 4-ingredient canned tuna patties are straight out of my aunt’s playbook from the lean years, when Fridays meant making something filling, cheap, and a little bit special out of what was already in the pantry. They’re crispy on the outside, tender and flaky inside, and come together with just tuna, eggs, a little low-carb binder, and seasoning. If you’re juggling work, kids, or just a long day, this is the kind of practical, budget-friendly dinner that feels like a small win: fast, satisfying, and made from things you probably already have on hand.
I like to serve these patties hot from the pan with a simple green salad dressed in lemon and olive oil, or next to steamed broccoli tossed with butter and salt to keep things low carb. They’re also great on a plate with sliced tomatoes and cucumbers, or over a bed of shredded cabbage or coleslaw mix for extra crunch. If you’re not strictly low carb, a slice of buttered toast or a small baked potato on the side makes this feel even more like a classic comfort dinner. A squeeze of lemon, a dollop of mayo or Greek yogurt, or even a little hot sauce on top really wakes them up.
Low Carb 4-Ingredient Tuna PattiesServings: 3
Ingredients
2 (5-ounce) cans tuna in water, well drained
2 large eggs
1/3 cup finely grated Parmesan cheese
1 teaspoon kosher salt and freshly ground black pepper, to taste (about 3/4 teaspoon salt + 1/4 teaspoon pepper)
Directions
Drain the canned tuna very well, pressing the lid or a spoon against the tuna to squeeze out as much liquid as you can. This helps the patties hold together and get crispy instead of soggy.
In a medium bowl, add the drained tuna and break it up with a fork into small flakes. Add the eggs, grated Parmesan cheese, salt, and black pepper.
Stir the mixture with a fork until everything is evenly combined and the tuna is coated with egg and Parmesan. The mixture should be moist but thick enough to scoop and shape; if it feels too loose, let it sit for 2–3 minutes so the cheese can absorb some moisture.
Using your hands or a spoon, divide the mixture into 6 equal portions and gently form each into a small, round patty about 2 1/2 inches wide and 1/2 inch thick. Press the edges together so they’re compact; this helps them stay intact while frying.
Heat a large nonstick skillet over medium heat and add just enough oil to lightly coat the bottom (about 2 tablespoons neutral oil or a mix of oil and butter if you like richer flavor). Let the oil heat until it shimmers.
Carefully place the tuna patties in the hot skillet, leaving a little space between them. Cook without moving them for 3–4 minutes, until the bottoms are deep golden brown and crisp around the edges.
Gently flip each patty with a thin spatula and cook the second side for another 3–4 minutes, or until golden brown and cooked through. Adjust the heat if they’re browning too quickly.
Transfer the patties to a paper towel–lined plate to drain any excess oil. Serve hot, with extra black pepper and a squeeze of lemon if you have it.
Variations & Tips
To stretch this recipe even further, you can make the patties slightly smaller and turn them into bite-sized tuna cakes for snacking or topping salads. If you want a little more flavor without adding more ingredients, bump up the black pepper and finish with a generous squeeze of lemon juice or a sprinkle of extra Parmesan right after frying. For a bit of heat, add a pinch of red pepper flakes or a few dashes of hot sauce into the mixture (this technically adds an ingredient, but it won’t change the basic formula). If you’re not strictly counting carbs, you can swap part of the Parmesan for 2–3 tablespoons of breadcrumbs or crushed pork rinds for a different texture. These patties reheat well in a skillet or air fryer the next day, which makes them handy for meal prep lunches. For food safety, always use tuna from cans that are not bulging, leaking, or damaged, and check the expiration date. Drain the tuna into the sink, not into a drinking glass or near ready-to-eat foods, and wash your hands after handling the raw egg mixture. Cook the patties until the centers are hot and the eggs are fully set, and refrigerate leftovers within 2 hours in a covered container, using them within 3 days.
