Making a pesto sandwich isn’t rocket science. But nonetheless, I will treat it as such and explain how to make THE BEST Grilled Tomato, Mozzarella, and Pesto Sandwich!

Two slices of whole wheat bread, one slice with basil pesto spread along the surface and the other with mayo.

How to make Grilled Tomato, Mozzarella, and Pesto Sandwiches:

  1. Cut two slices of bread, I opted to use whole wheat bread because this is what we usually have on hand.
  2. Slather one side of bread with mayo, and the other with basil pesto.
  3. Top your bread with tomatoes, a sprinkling of salt, and then the mozzarella
  4. Grill on a panini press. I linked the one we own, I use it ALL the time! Meat sandwiches, grilled cheese, grilled tomato, mozzarella, and pesto sandwiches to name a few. If you don’t own a panini press, you can warm up a skillet on your stovetop and grill your sandwich via thought route.
  5. Eat and enjoy!

Do you need to use homemade basil pesto to make a pesto sandwich?

  • No. Homemade basil pesto isn’t necessary. I LOVE homemade pesto, but unless you have a green house with a large basil plant, chances are you don’t have homemade basil on hand during the winter months.
  • However, if you’d like to give homemade pesto a shot, I have a great recipe right here. Basil pesto is easy to make and it tastes delicious!

How much mozzarella should I use when making a tomato sandwich?

I use anywhere from 1.5-2 oz of sliced mozzarella on each sandwich I make.

Once you see how much or how little 2 oz of cheese appears, you might opt for adding a touch more mozzarella on your sandwich, or slightly less. But 2 oz has proved to be my families sweet spot.
