Servings 2 tartares


For the avocado layer

  • 2 Avocado peeled and diced
  • 1/2 Lemon juiced
  • Sea salt, to taste

For the tuna layer

  • 2 cans Tuna (in water) well drained
  • 1/2 small Red onion minced
  • 1-2 tbsp Balsamic vinegar
  • 1 tsp Dijon mustard (or more if prefered)
  • Sea salt, to taste
  • Black pepper, to taste

For the topping

  • 5-6 Mixed cherry tomatoes diced
  • Fresh basil, to top roughly chopped


  • Combine the ingredients for the avocado layer in a bowl.
  • Combine the ingredients for the tuna layer in a seperate bowl. Taste to check if more seasoning is needed. But make sure the tuna mixture doesnt get too wet.
  • Assembly the tuna tartare by placing half of the avocado mixture at the bottom of a plate using a round mold (see note 1) making sure it gets a circulare form and stays in place. Gently push the avocado down to make sure it sit. Place the rest of the avocado in a seperate mold on a seperate plate.
  • Next divide the tuna layer between the two molds, also pressing it down gently to make sure it stays in place.
  • Top the tartare with diced cherry tomatoes and fresh basil.
  • Gently remove the mold and serve immediately.
