How to Make a Tuna Melt (2 Ways!)

Simply mix together the tuna fish mixture then start layering the ingredients on top of a thick piece of bread. Melt it all together and you have the perfect classic tuna melt sandwich! Make this a complete meal by adding in sweet potato fries or air fryer potato chips for the best flavor combination.

  1. Tuna Fish Mixture: In a medium-sized bowl combine the tuna, mayonnaise, celery, red onion, dijon mustard, parsley, salt and pepper.
  2. Prepare Bread: Butter each slice of bread. Putting the butter side down. Then add the cheese on the unbuttered side.
  3. Layer the Sandwich: Add the tuna mixture on top. Top with tomato and additional cheese.

Skillet Method:

  1. Preheat a Skillet to Medium Heat: Add the sandwich to the skillet and heat for about 2-3 minutes until cheese starts to melt and is golden brown. Flip to the other side and cook until the cheese is fully melted then the sandwich is golden brown.

Broiler Method:

  1. Preheat Broiler: Spread the bread butter side up and toast for a couple of minutes. Then top with cheese, tuna mixture and broil for 2-3 minutes until cheese is melted.

Tasty Variations

Here are a few easy ways to make your tuna melt just the way you like it! It’s so fun to try different variations.

  • Make it Low Carb: Wrap it up in a lettuce wrap, use keto bread, or have an open-faced sandwich to help reduce the amount of carbs on this sandwich.
  • Keep it Health Conscious: Find a low-sodium or calorie tuna fish that works best for you.
  • Use Different Cheese: Use your favorite type of cheese here! I always go for classic cheddar, but asiago cheese, jalapeño jack cheese for some spice or Colby jack cheese are all great options!
  • More Toppings: For extra texture and flavor try sliced pickles, soft avocados, or lettuce.
  • Bread: Try an English muffin, white bread, whole grain bread, whole wheat tortilla, or a thick bagel for different variations of tuna melt sandwiches.

  • Tuna Salad: Store in an airtight container in the fridge for up to 4 days.
  • Tuna Melt: Your prepared tuna melt will stay good for a day or two either wrapped in plastic wrap or stored in an airtight container. Keep in mind, the bread may begin to get soggy as it sits.
