Slow-Roasted Tomato Jam #Recipe by Leslie Karst

 

Here in Santa Cruz, we’re lucky enough to still have the last tomatoes of the season on our vines. But with the cool weather now upon us, it was time to do my final harvest this last week. And boy, was it a harvest—my single Roma tomato plant bore some fifty pounds of fruit this year!


So what to do with all those glorious tomatoes? I decided to try my hand at a Slow-Roasted Tomato Jam—a sweet and savory condiment that goes perfectly on crackers with cheese, but would make for a luscious pasta sauce as well.



This recipe is for about five pounds of tomatoes, so if you use fewer (or more!), you can adjust the amounts of the other ingredients accordingly. And truly, the measurements are mere guidelines—feel free to alter them as your palate desires. 

 




Slow-Roasted Tomato Jam


Ingredients


¼ cup olive oil

1 med. onion

5 pounds tomatoes (Roma are best, but any will do)

1 teaspoon each, salt and black pepper

1 to 2 teaspoons sugar, to taste

2 tablespoons balsamic vinegar



Directions


Preheat oven to 300° F.


Line a large roasting pan with foil, and drizzle half the oil into it. 

 

 

Slice the onion thinly, then spread it out over the bottom of the pan. 





Cut the tomatoes into ½ to 1” chunks, and spread on top of the onions. Sprinkle the salt and pepper on top, then drizzle with the remaining oil.





Place in oven and roast, stirring every half hour or so, until the liquid evaporates and the tomatoes darken and become thick and gloppy. 

 


This could take anywhere from two to four hours, depending on the moisture content of your tomatoes. And you may want to crank the temperature of the oven up to about 400° F for the last half hour or so, to hasten the process. Just make sure to keep an eye on it, so the tomatoes don’t burn!


Once sufficiently cooked, taste the jam and add sugar as desired (1 to 2 teaspoons should be plenty). Finish by stirring in the balsamic vinegar. 

 



The tomato jam will keep refrigerated in glass jars for several weeks, or frozen in freezer bags for many months.

  1. Yum! I made tomato jam a couple years ago, and am sold on it. My garden did not produce enough this year to make any, but I will definitely add it to my must-make list. And thank you, Leslie, for this recipe. I'll add it to my collection, too.

    It is very good on grilled cheese sandwiches in the winter. Elevates that simple sandwich to a whole new level.

    1. And it's now in the 40s in Santa Cruz, too. Brrrr! (Says the California native.)

  3. This does sound tasty, with multiple sues.
    I'm not having much luck growing tomatoes in south Florida. Critters attack the fruit and the latest plant has black spots.

    1. Yes, it's hard to grow tomatoes where it's humid. Good luck next year, Libby!

  6. I love this but like most of the others, our tomatoes are long gone. But I have high hopes for next fall and I will use your recipe then.
