By swapping the bread for the zucchini, you will ultimately be making a super delicious low carb tuna melt.

How to Make a Tuna Melt Recipe

Making a classic tuna melt sandwich is quite simple. But making this recipe is even better and more rewarding because they are much healthier.

While you heat the oven to 350, cut the zucchini in half lengthwise, then scoop out the insides. You can save the insides and make with eggs or add to your next vegetable soup!

Then, place the zucchini into the prepared baking tray, and spray with cooking oil. Season with salt and pepper to taste, then place into the middle rack of the oven and bake for 12-15 minutes, or until just tender.

In a mixing bowl, add tuna, celery, red onion, yogurt, dill, mustard, lemon juice, and jalapeño. Mix until combined, then taste and season with salt and pepper as needed.

Once you have the mixture ready to go, stuff the zucchini boats with the tuna mixture then sprinkle with cheddar. Continue to bake in the preheated oven for about 10 minutes, or until cheese is melted. Top with any additional toppings of choice and  Enjoy!

Tuna Melt Ingredients

The ingredients you need to make a tuna melt are as follows:

  • Tuna: You can use canned tuna. In water or oil. But I prefer using white albacore in water.
  • Zucchini: One zucchini will be sliced in half. You may use either the green or the yellow zucchini.
  • Celery: For those who don’t like celery, you can skip it, but it brings out the unique flavor of the tuna melt.
  • Onion: I used red onion, but if you don’t have this handy, you can use sweet or cooking onions.
  • Greek Yogurt: This is used in place of the mayonnaise. Other options could be hummus or avocado.
  • Cheese: Any cheese of choice will work, but I prefer using wither mozzarella or cheddar.
  • Herbs and condiments: some additional herbs and condiments that can be used are mustard, dill, salt and pepper, garlic, and parsley.
  • Toppings: Green onions, corn, jalapeno, and chopped tomatoes.

Frequently asked questions

Here are some questions that are usually asked by others who are looking into making this recipe.

What is a tuna melt?

The word melt in a tuna melt sandwich is basically the melted cheese in the sandwich or recipe. When referring to a tuna sandwich,  it contains bread, cheese, and some sort of filling such as tuna. A tuna melt is simply melted cheese on a tuna sandwich. This is sometimes heated and served hot, and thus the formation of the melted cheese.

What’s the best cheese for a tuna melt?

Most common cheeses used are either cheddar cheese or mozzarella cheese. Other white cheeses like swiss, American or provolone will also work.

What goes with tuna melts?

Something crisp with some texture will do well. So, potato chips would be a good choice (try used baked) or some fresh vegetables such as Tomatoes would also be great as sides. Also, try a simple salad tossed in with vinaigrettes. Avoid anything creamy since your tuna melt will already be heavy on the creamy flavor.

How many calories in a tuna melt?

A basic tuna melt sandwich should have about 350 calories. This is because of the bread and mayo used in the classic sandwich recipe. But, swapping the bread with the zucchini and using greek yogurt instead of mayo will make a huge difference in this recipe. They are much more healthy and come out to 84 calories a piece!

    We made these last night and they were delicious and so easy (cooked them in the toaster oven to try and keep the heat in the house down). The jalapeños made it!

    I also doubled the tuna salad recipe and I’m so glad I did…it was delish and will make a great lunch today!

    (I didn’t have any fresh dill so I just sprinkled dried dill on…I bet fresh would taste even more amazing!)

    So glad I found your site (via IG).

    Excellent use of zucchini squash! I didn’t change a thing and it turned wonderful for lunch or a light dinner.

    Love the tuna fish boats. So yummy. I put additional jalapeños on mine cause I love the heat and use Mayo. Still has low carb so works for me. Eat this 2-3 times/week! Can’t wait to try lasagna this way.

    Can’t eat dairy, so I used mayo instead of Greek yogurt (bad, I know) and Daiya mozzarella instead of cheddar. SO DELICIOUS and quick. Reminded me of when my host mother served me this dish in France. Thank you!

    Love the recipe but your website drives me mental. Can’t you just sell an ebook or something instead of having all of these annoying ads?

    I made this dish the other night but I just made some small changes since I didn’t have some of the ingredients but it was delicious nonetheless. The leftover turned into the next day’s lunch so win win
