Ingredient information
CANNED TUNA - The choice is yours if you want canned tuna packed in oil or water. I used tuna in oil because I wanted the most flavor I could pack into this tuna melt sandwich.
TARTAR SAUCE - I always make tuna salad using the tartar sauce recipe I've been making for 30-plus years. My family has always loved the flavor of my tuna salad, so I won't mess around with my tried-and-true recipe.
Feel free to use your own tartar sauce (store-bought will work, too), but I urge you to try my recipe. It's a winner, takes less than 5 minutes to make, and uses basic refrigerator and pantry staples.
BAGEL - I used an everything bagel for this particular sandwich shown in the photos because those are the ones I like the best. Feel free to use whatever type of bagels you prefer.
CHEDDAR CHEESE SLICES - You can never go wrong when choosing cheddar cheese for a tuna melt. Just make sure your slices are as large as your bagel because you want to make sure you get all the cheesiness that makes a tuna melt, melt!
SHREDDED PARMESAN CHEESE - Why not top the melt with more cheese? I always have Parmesan in the fridge, so it was a no-brainer. Feel free to omit it if needed.
How many tuna melts does this recipe make
I guess that depends on if you call two halves, two sandwiches, or one. In the recipe, I'm calling two, one, so this recipe makes three servings of two each. Who's on first? LOL
How long will tuna salad keep in the fridge
Store the prepared tuna salad in an airtight container in the refrigerator for up to 5 days. I do not recommend freezing the tuna salad because the consistency will change once thawed.
FAQs
Use your favorite brand of canned tuna fish. Yellowfin and Albacore are both great choices. As stated above, I used tuna packed in oil for this particular melt, but I've also used tuna packed in water for these melts when I want to keep the calories just a wee bit lower.
Yes. Sure. Use what you have, or make your own. I like to make my own tartar sauce, but don't let me stop you from using store-bought tartar sauce if that's what you have on hand or prefer.
I don't recommend it. Because this recipe is mayonnaise based, when the tuna salad thaws, the texture will be "off," and the sauce will likely split and be oily.
Any flavor you wish!
Of course.
Additional add-in suggestions
Feel free to add whatever herbs and spices you enjoy most to this tuna melt sandwich. Grated fresh ginger would make an excellent addition, as would chopped capers, pimentos, minced red onion, celery, and of course, citrus zest.
Ingredient substitution suggestions
Feel free to use a vegan mayonnaise instead of the egg-based mayonnaise in this recipe. You can also use a smashed avocado instead of the mayonnaise for a completely different twist on a tuna melt sandwich.
Monterey Jack, Colby Jack, Pepper Jack, Swiss cheese, and American or Provolone cheese slices would all make great substitutions (or additions) to this updated tuna melt sandwich.
