4 Ingredient Classic Tomato Sandwich (Easy & Delicious)

It’s mid-summer, and your garden is flourishing and producing delicious tomatoes! I’m sure you have lots of ways to use up all of this goodness, but have you ever tried a tomato sandwich? This is my all-time favorite way to savor the taste of summer.

Tomato sandwiches are eaten all over the world, but there are many people who have never heard of them.

There are variations to how people have learned to eat them depending on where they live. My favorite way consists of bread, homemade mayo, and tomatoes. That’s it!

Start With Homegrown Tomatoes

If you are like me, you planted those tomato starts and enjoyed every minute of watching them grow. If you had some struggles and know you need to change a few things next year, check out the best way I have found to plant and grow tomatoes.

For tomato sandwiches, each heirloom tomato has its own flavor, but they are all good on a sandwich. There is no “best tomato” in my opinion!

How Do You Make A Tomato Sandwich?

You have your first few ripe tomatoes! You’ve added them to salads, or made fresh salsa, but now let me teach you how to make a tomato sandwich.

Ingredients Needed:

  • Bread – two thick slices of toasted white bread are my favorite, but any bread will do! I'm looking forward to trying this with some homemade sourdough this summer with tomatoes grown in our first South Carolina garden!
  • Tomatoes – either a large slicer tomato or multiple slices of smaller tomatoes. My favorite is to use one nice thick slice from a large tomato similar in size to my bread.
  • Mayo – as much or as little as you see fit. Homemade mayonnaise adds extra goodness.
  • Salt – salt brings out the tomato flavor, don't skip it! My favorite is a good flaked sea salt like this.


Toast two slices of bread and cover the inside of both with mayo. Slice the tomato and place on bread. Sprinkle it with salt and cover with the other piece of bread.

I prefer the classic recipe, but there are add-ons you can use if you choose to. Here are a few ideas:

  • Bacon
  • Butter
  • Mozzarella cheese
  • Lettuce
  • Pepper
  • Basil

Grilling it after assembling it is also an option. The beauty of this sandwich is that you can totally craft it to your own taste!
