  • 1 tablespoon olive oil
  • 1/2 medium onion finely diced
  • 2 cups baby spinach chopped
  • 2 cloves garlic minced
  • 3 5-ounce cans tuna or one pound cooked tuna
  • 1/4 cup almond flour
  • 2 beaten eggs
  • 1 tablespoon mayonnaise
  • 1 tablespoon lemon juice
  • 2 tablespoons chopped fresh parsley
  • 2 tablespoon chopped fresh dill chopped
  • salt and pepper to taste


  • Heat the oil in a pan on medium heat. Add the diced onion and minced garlic and saute for a minute. Then add the chopped baby spinach and saute for another 1-2 minutes or until the spinach is wilted.
  • Transfer the onion spinach mixture to a bowl and let it cool. You can place the bowl in the fridge to speed this up.
  • Preheat your oven to 400 degrees fahrenheit.
  • Drain the cans of tuna and add the tuna to a mixing bowl along with the cooled vegetables, almond flour, eggs, mayonnaise, lemon juice, parsley, dill, salt and pepper.
  • Use your hands to dig in and mix everything together, breaking up any large chunks of tuna. The finer the mixture, the easier it will stick together.
  • Use a medium cookie scoop to scoop out evenly sized amounts of mixture. Use your fingers to mold this into a ball, then place it on a parchment lined baking tray.
  • Bake the tuna meatballs for 20-25 minutes, or until lightly golden.



  • The recipe makes 20 tuna meatballs.
  • For picky eaters when it comes to seafood, this recipe is more mild in flavor than my salmon patties, so give it a try!
  • If your meatballs are too soft you can add a little more almond flour or coconut flour (which is highly absorbent).
  • This is the cookie scoop I use and love.
