A few special ingredients join forces with ripe tomatoes for a memorable sauce that’s deceptively easy to make.
The taste of marinara sauce made with in-season tomatoes is divine. Finding the time to peel and seed the required tomatoes, however, can be enough to make you buy a jar!
I decided to try a new approach which eliminated these tedious steps. The first time I made this sauce, I turned around and bought more tomatoes the very next day so I would have some to freeze.
I recommend plum or Roma tomatoes for this recipe as they have fewer seeds than other varieties. They also have a lower water content, so you’ll get thicker sauce without having to cook it down as long as sauce made with traditional slicing tomatoes. This translates into a higher yield.
Additionally, the comparatively thicker skins of plum tomatoes, which I blend in, further contributes to a richer, thicker sauce. (And who wants to peel tomatoes anyway!)
In lieu of the traditional herbs, I stir in pesto. The savory paste effortlessly lends nuanced, fresh flavor and richness to the sauce. Balsamic vinegar, in turn, provides a hint of sweetness and acidity that enhances the natural flavor of the tomatoes and complements the herbaceous, nutty notes of the pesto.

Mouth-watering on pasta, this sauce is equally perfect on pizza or in any recipe that calls for marinara sauce.
