Roasted Balsamic Tomato Sauce will reward you with a delicious aroma while it cooks in the oven.
Every August, I end up making a couple of batches of this sauce, when the prices for plum tomatoes hits the floor, but it works equally as well with any kind of tomato you’ve got too many of in your garden.
Preheat your oven to 425° and spread olive oil all over the bottom of a sheet pan. Wash your plum tomatoes and slice them in half. Sometimes, I’ll use my thumb and pull out the seeds and pulp. If I’ve got the time, though, I’ll lay the tomatoes out, cut side down, on the sheet pan, and roast them by themselves for 30-45 minutes, allowing all the juices to dribble out, and thicken and caramelize. Take them out of the oven, and turn the tomatoes over, skin side down. Once that’s done (or if you’re pressed for time), mix a large onion, sliced, and a couple stalks of celery, chopped, and a few whole cloves of garlic, along with any other excess summer produce you’ve got, in a bowl with some more olive oil, balsamic vinegar, salt and pepper, and spread it around the tomatoes — add a little more balsamic for the tomatoes, too. Roast in a hot oven for 45 – 60 minutes, or until everything is collapsed and roasted.
Allow it to cool a bit, and then transfer to a blender. You’ll probably get lots of sticky carmelized goodness left on the sheet pan, so deglaze on the stove top with a little water, and add that into the blender. Blend until smooth. Add more water for a smoother consistency, or use chunky, like a relish.
Since the tomatoes are high in acid, I plan on putting aside some jars for eating later this year, but you could freeze it, too. Tips for canning tomato sauce can be found on CanningUSA.com.
