In a large mixing bowl, combine the well-drained tuna, panko breadcrumbs, grated Parmesan cheese, chopped red onions, minced garlic, dried parsley, onion powder, dried dill, crushed red pepper, celery seeds, black pepper, salt, mayonnaise, lemon zest, lemon juice, and lightly beaten eggs. Mix thoroughly until all ingredients are fully incorporated.

With your hands, scoop roughly ¼ cup of the mixture and shape it into a patty, ensuring it’s about ¾ inch thick. Press both sides of the patty into additional panko breadcrumbs before placing it on a plate. Repeat this process until all are shaped.

In a large skillet, heat about 3 tablespoons of vegetable oil over medium-high heat. Allow the oil to heat for approximately 2 minutes, until hot enough to fry.

Gently place four to five patties into the skillet. Cook for 3-4 minutes on one side until golden brown and crispy.

Carefully flip each patty using two spatulas. Cook for an additional 3-4 minutes on the other side until golden brown and crispy.

Continue the cooking process with the remaining patties, adding more oil as necessary and wiping the skillet clean between batches for optimal results.

Once all patties are cooked, serve them warm, either on their own or paired with a side like fresh salad or coleslaw.
