The world’s best tomato sandwich

This tomato sandwich with mayo is so simple it barely needs a recipe, really just assembly instructions. But here it is anyway. I’ve had one of these for lunch almost every day since my backyard tomatoes started ripening!

Yesterday I wrote about how obsessed I am with tomatoes, so much so that I grow them hydroponically in winter.

Today I’m going to share with you my favorite tomato sandwich. It’s really too simple to need an official recipe, but the obsessive part of me took over, so here’s an official recipe!

The key to this sandwich is to use a really ripe tomato and soft, white bread. Yes, it has to be soft and white. Otherwise, it’s just a different sandwich. I mean, I love a hearty wheat bread, but that’s not the flavor and texture we’re going for here.

Same with adding things like bacon or cheese. Totally valid additions…for a different sandwich. For this sandwich, the tomato has to be the star! (But if you’re in the mood for a BLT that really lets the tomatoes shine, you have to check out my recipe for a deluxe BLT with marinated tomatoes!)

So go find a fresh, ripe tomato, and get to work. But I warn you: this simple tomato sandwich is addictive.

World's Best Tomato Sandwich Recipe

This tomato sandwich with mayo is so simple it barely needs a recipe, but here it is anyway. I've been obsessed with this sandwich all summer! The key is to use really ripe, juicy tomatoes that will soak into the bread a bit. Eat it as is, or cut it in quarters and serve it as an appetizer. #tomatoes #vegetarian #summer

This is my absolute favorite way to enjoy fresh, ripe tomatoes in summer and early fall. The bread has to be white, and the tomatoes have to be really ripe.

Prep Time 2 minutes
Total Time 2 minutes


  • 2 slices white bread, not toasted
  • 1 large tomato, very ripe
  • Hellmann's Mayonnaise
  • 1 large pinch kosher salt
  • 1 small pinch pepper


  1. Spread mayonnaise on both slices of bread
  2. Slice tomato thick, and layer onto one slice of mayonnaise-covered bread
  3. Sprinkle tomatoes with kosher salt and pepper to taste
  4. Put the other slice of bread on top, mayonnaise side down
  5. Cut in half and enjoy with plenty of napkins!


The bread has to be white. The mayonnaise has to be Hellmann's (unless you live in a part of the country where Hellmann's is Best Foods, then you can use that). And the tomatoes have to be really ripe and juicy! 

Did you make this recipe? I'd love to see it!

I've always loved Hellmann's, but then I discovered Whole Foods Organic Mayo. It's even better. Perhaps because it's more lemony. Just a suggestion! I love tomato sandwiches.
