Keto Tuna Melt Sandwich

Yield: 2 servings


  1. 1 5 oz. can of tuna in water, drained
  2. 1 rib of celery, finely chopped
  3. 1-2 tablespoons chopped onions
  4. 2 tablespoons avocado oil mayonnaise (or any keto-friendly mayonnaise)
  5. Salt and pepper, to taste
  6. 4 slices keto bread (such as almond flour bread or cloud bread)
  7. Butter or ghee for grilling
  8. 2 slices keto-friendly cheese (such as cheddar or mozzarella)


Prepare Tuna Salad:

In a small mixing bowl, combine drained tuna, finely chopped celery, onions, avocado oil mayonnaise, salt, and pepper. Stir until well mixed and set aside.

Assemble the Sandwiches:

  1. Lay out 4 slices of keto bread.
  2. Divide the tuna mixture evenly between two slices, spreading it evenly over the bread.
  3. Place one slice of cheese on each tuna-topped bread slice.
  4. Top each with another slice of keto bread to form sandwiches.

Cook the Sandwiches:

  1. Preheat a non-stick frying pan over medium heat and add butter or ghee.
  2. Carefully place the assembled sandwiches in the pan.
  3. Cook until the bottom side is golden brown and crispy, and the cheese begins to melt.
  4. Gently flip the sandwiches with a spatula and cook the other side until golden brown and the cheese is fully melted.


Once both sides are golden and the cheese is melted, remove the sandwiches from the pan. Allow them to cool slightly before slicing each diagonally into halves. Serve hot and enjoy!
