Heirloom Tomato Leek Cheddar Tart.

August 31, 2018

One of my favorite recipes of the summer

Say goodbye to August with this Heirloom Tomato Leek Cheddar Tart!

This tart is easily my favorite savory tart. It is flavorful, cheesy, a little acidic, and flaky. What more could you want in a tart? I made it at about 11am today, and by the end of lunch time, it was gone! No traces of the tart.

This recipe is best made with sweet, local tomatoes since they are really the star of the show. My favorite type of tomatoes are heirloom since I love their sweet aftertaste so I went with those. However, if you prefer cherry tomatoes, go for those! Simply cut into little slices, and add to the tart.

Also, not to mention, this tart is pretty picturesque. Don’t you agree?
