San Marzano are the best choice of tomatoes for paste. They stay sweet even when cooked down to a paste and are easy to peel. They need a good cage because they are indeterminate and vining so make sure to keep them organized! These tomatoes are unique in that they prefer full sun exposure.


Plant 1/4 inch deep into well-drained soil with full sun. Keep the soil consistently moist and provide support for the vines as they grow. Once harvested, these tomatoes can be used for making sauces, pastes, and even oven-dried for a concentrated flavor. Their firm texture also makes them great for slicing into salads and sandwiches.
