Tuna Melt

Diner comfort food just got a makeover! This classic tuna melt has the perfect amount of crunch, melty cheddar cheese, and veggies. Melts are one of my favorite types of lunch sandwiches. If you love a hot sandwich, you should also try these Open-Faced Turkey Melts and Egg and Tomato Breakfast Melts. If you want a cold sandwich, definitely check out my Open Faced Tuna Sandwich with Avocado.

When I was a kid, my mom owned a luncheonette where she was the cook. She would often make me a tuna melt, which I loved! Tuna is such an easy protein since it requires very minimal prep work – just open up the can and drain. If you want to turn tuna into a larger meal, we love our homemade tuna casserole.

Are tuna melts good for you?

Adding veggies to your tuna and serving it open-faced makes this classic sandwich healthier and lighter! By using only one slice of bread, you cut the carbs in half. For a more low-carb tuna melt, try these tomato tuna melts.

Use your favorite whole grain bread – I love Dave’s Killer Bread. It’s organic, non-GMO, and tastes great. Another good option would be to use homemade bagels instead of sandwich bread.

How To Make Tuna Salad

There are so many ways to make tuna salad, but this recipe is my go-to. Start with a can of tuna, drain it, and mix in mayonnaise, chopped red onion, celery, carrots, and a little red wine vinegar. The vinegar gives it a little zing that makes it delicious!

Tips to make this quicker:

To speed up the prep time, I love using my Cuisinart 4-cup mini food processor (affil link), I put the carrots, celery, and onion in and pulse a few times, which saves a lot of time.

What sides go with tuna melts?

This healthy tuna melt is excellent on its own, but you can definitely add a side if you want to round out the meal. You could serve your tuna sandwich with a green salad or a cup of soup. This Tomato Basil Soup or French Onion Soup would be delish. You could also serve it with potato salad or a dill pickle.

Variations:

  • Swap the whole grain bread for bagels, sourdough, English muffins, or whatever you have on hand.
  • Use another cheese like Swiss or gouda in place of the cheddar.

  1. Delicious, but iused the 5 oz. can of tuna. Will definitely make again!

  2. 14.5 oz. is a large can. Are sure it’s not the 5 oz can?

  3. Delicious! I substituted pink salmon (realized the can is expiring in a couple of months), but it really hit the spot. Extra tasty with the grilled bread. Thanks, Gina!!!

  4. Um – so good! I did make an adjustment b/c I realized I had red cooking wine and after some quick research – I realized that was NOT the same as Red Wine Vinegar (hehe). So, I used Hoisin Sauce! Y U M M Y! I also didn’t have celery. I used red bell pepper. I had one serving and am stuffed! I loved that I chopped all this up earlier and put in one bowl, then when I was ready, just opened the tuna, added some mayo, hoisin sauce, salt, pepper and bowl of yummies! Plan on eating this for lunch alot! Thanks,

  5. Yum! I’ve never added red wine vinegar to my tuna and was skeptical but I think this one little ingredient has a lot to do with how good this tuna salad turned out. I used the Sara Lee Delightful 45 calorie white bread and a slice of the Sargento Ultra Thin sharp cheddar slice. This was a really satisfying and quick to prepare lunch.  Preparing in a pan instead of the toaster oven also made it better than my usual tuna melt! Thanks for another yummy recipe!

  6. We really enjoyed this tuna melt and have added it to our meal planning rotation. For 231 calories a serving it tastes amazing and it is very satisfying. We love it.

  7. I love this recipe but I was wondering…If I made a double batch of this recipe, how long would it last in the fridge?

  8. I don’t even like tuna and I loved this!  Very creamy and tasty!

  9. I absolutely loved this recipe! Winner! Winner!

  10. Warning: this tuna melt will change your life!

    Okay, in all seriousness, this is absolutely delicious. I added an extra 0.5 tablespoon of mayo, fresh dill and fresh parsley (because I had them on hand). I also layered the tomato on the bottom, tuna in the middle, then cheese cheese on top – the warm juicy-ness of the tomato was really nice once it came out of the oven.

    I doubled the recipe and will store the remaining mix in the refrigerator for tomorrow’s lunch.

  11. I just made it!!! Sooooooooooooo good!!! This is a great sandwich. I used white bread and yellow onion. Still delicious….

  12. This recipe is absolutely DELICIOUS!!!! This was my first ever Tuna Melt & I have to say, it’s going to be hard to beat! I was looking for a healthy lunch idea and had most of the ingredients on hand. I didn’t have Red Onion, so I omitted that and substituted Apple Cider Vinegar bc I had it on hand. Hardest part is only eating 1/2 of the sandwich! AMAZING!

  13. Is the serving 2 slices or just one?

  14. Just to make everyone laugh…. I wanted a quick meal that I could grab anything I needed at Target. I write my list, run to the store, can’t find 14.5 oz cans of tuna. So I do some math, grab 3 cans and come home. Yep… reading really is fundamental! The recipe is delicious and I can make a double batch tomorrow when I have more time.
    Thank you Gina from the bottom of my non cooking heart! All of your recipes taste wonderful and you write them in a way that I can actually pull them off!🤣

  15. I love all the meal plans you’re sharing. My husband and myself just started weight watchers and appreciate the points you’re including. The shopping list are wonderful and make juggling life with 3 kids easier! I am looking at ordering your meal plan book too!

  16. Hands down the BEST tuna salad EVER! So simple! So good! Have had it for Lunch, Dinner then lunch again….3 meals in a row! Thats how good it is!!! Thank You Gina!!!

  17. I am that horrible person who rarely measures ingredients. I sub sour cream for the vinegar, provolone for cheddar and added dried dill. Still phenomenal.

  18. Will it be less points if I use 1 point bread and fat free Greek yogurt ?

    • I have found you can sub some may for yogurt but you really need the mayo taste and the oil in it brings the ingredients together better. Plus, there is just 1 1/2 tsp per serving. Not much. Bread exchange should work. Most low calorie breads are 1 point vs 2. I think using a low fat english muffin at 3 points would be really good too. 

  19. .Just made this the other day. Loved it. I put a little more chopped red onion in it.
