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!

Super easy to make and very tasty! This recipe has been in rotation for a few years now and we never tire of it. The only thing i omit is the celery (personally i don’t like it). For the rest, this recipe is perfection. Thank you for sharing ๐

These are sooo good. They already look tasty from the pictures, but are even more fabulous once tasted. So good.
Thanks Jay
This looks super yummy and I cant wait to try this. Is the serving size the whole zucchini ?
It’s amazing. So half of the zucchini will be one serving. So one zucchini “boat”

Awesome! Was so excited to try this as Tuna melts are a staple for a later evening meal! Love this!
Thanks for the feedback!
I am making this now, I just wonder what do you ladies are doing with the inside of the zucchini? I don’t really want to waste anything
Hi! you can use the insides and make an omelette with eggs, or save/freeze and use it in soup.
I actually used in the tuna mix. Turned out awesome.
These were so so good. I happened to have all of the ingredients for this recipe on hand so it made for a quick and delicious dinner. And that tuna, AMAZING! I Just love dill. I used two cans of tuna, so I have plenty leftover. I look forward to having it again for lunch tomorrow. Thank you so much for sharing this recipe.
