Avocado Tuna Melts are mine.

Avocado tuna melt recipe

I started making this tuna melt recipe fairly frequently when we lived in Texas and Bart would come home for lunch and we were out of leftovers.

The first time I made an avocado tuna melt, I told him on the phone what I was making and he said, “Oh, okay. I’ll probably just eat something else.”

So I only made one tuna melt sandwich for me.

I . . . never made that mistake again. Now I always make him two avocado tuna melts.

I’m a quick learner.

Author Janssen Bradshaw


  • 4 slices of bread sourdough is my favorite, but anything works
  • 5 oz tuna
  • 1 spoonful mayonnaise more or less, depending on if you like or love mayo. I love that stuff.
  • 1 Tablespoon mustard
  • 1 to mato diced
  • 2 avocados
  • 4 ounces cheddar cheese shredded or sliced
  • salt and pepper


  1. Toast your bread.
  2. While it toasts, stir together your tuna (drain it first, if it's in cans), mayo, mustard, and tomato. Salt and pepper to taste.
  3. Mash up your avocados and spread it on your bread, then top with tuna mixture and sprinkle with cheese.
  4. Broil for 2-4 minutes (keep a close eye on it!), until the cheese is hot and bubbling. Dust with pepper, if you're a pepper lover like me, and serve immediately.

    We love tuna melts – – but I'd kind of forgotten about them…and I've never tried avocado with mine – thanks for the tip!

    This looks delicious! I'm not *insane* about tuna (although I am, like you, a mayo lover), but for some reason I always have a huge tuna stockpile in the pantry (because it's cheap and healthy, I guess?), so I keep searching for new ways to use it up. This looks really tasty, especially with the avocado!

    Ooo, this looks great! I've never paired tuna and avocado, even though I love avocado! Our family recipe for tuna melts is tuna+mayo+green chile on your choice of bread, toast and top with raspberry preserves. This is what my grandpa made for my grandma on their first date! (So, obviously a winner.)
