Roasting Fresh Tomatoes Make Sauces Taste so Much Better

I love sweet tomatoes straight off the vine in salads and just sliced for a luncheon plate or a sandwich.  But what to do with the excess?   You can freeze and can them, but my favorite way to use them when I have extras is to roast them and then use them for sauces.

If you have never done this before, you are in for a treat.  Roasting them is so easy.  Just follow these steps.  Preheat the oven to 450 degrees F.

Plump Roma Tomatoes

I started with plump Roma tomatoes this time. They are plentiful and not too watery to start with.Sliced tomatoes ready for roasting

Slice the tomatoes in half and lay them cut side down on a baking sheet sprayed with a little Pam cooking spray.  Remember to cut out the area where the tomato joined on the vine for easy skin removal later.Roasted tomatoes with the skins on

Roast the tomatoes for 15-20 minutes until the skins start to wrinkled.    Mine took about 20 minutes.Use tongs to peel the skins from roasted tomatoes

Use a pair of kitchen tongs to gently remove the skins from the tomato flesh.  If you slice the place where the tomato joined the vine before roasting, they will come right off with very little effortRoasted tomatoes with skins removed

These have all had the skins removed and only the tomato flesh remains. These may look just like whole canned tomatoes but you won’t believe the difference in taste.tomato skins

    Hi! So I followed these directions but used early girl tomatoes and mine ended up really watery and most of them did not come out of their skins very well (though I did snip off the part where the stem was attached). Any idea what I did wrong? I definitely cooked them a long time and I am wondering if the type of tomato matters….

      Hi Laura,

      How long did you cook them?

      I have used two types of tomatoes. Both worked fine. Mine have pretty good substance when cooked and I did not have to roast them long for the skins to shrivel.

      It could have to do with how ripe they are, since more ripe ones start out more juicy?

    This worked great for me, but yes it did not work on under ripe tomatoes, I cut off portions that were under ripe, after roasting.
    My question is about the seeds. We where blanching and then de seeding, I like the flavor of the roasting much more. Do you de-seed for your sauce?
    I used a strainer, but the texture was then too thin, for the rustic sauce I like. Any suggestions?

      Hi BeckE. I did not de-seed at all and it did not make any difference to texture or taste.

      And, yes, they would need to be somewhat ripe for it to work, I would think or you would have to roast so long they would get watery.

    can you can these for use later? what is shelf life if so?

      They will keep for a while in the fridge, (perhaps a week) but I normally use them right away. I would guess that you could also freeze them but they would lose some of the flavor. Carol

    My problem is the same as Laura’s. Could I use something to thicken it up, and if so, what would you suggest?

    Hi Shanna. Not sure what to thicken it with. Mine did not produce the juice that yours and Laura’s did.

    The only thing I can think is when you actually make the sauce with them, to cook it longer with an open pan. This normally reduces a sauce well and should get rid of the watery texture. Carol

    I was taught to make homemade sauce from my Italian grandmother Years ago . ( not telling how many years ) . You can make sauce from any tomato however the roma tomato or plum tomato is the best for sauce because they are meatier than slicing tomatoes . She would actually soak the tomatoes in hot water and the skin would come off . Roasting them sounds yummy though and I will try that . She also smashed them in a colander to remove the seeds that can make a bitter taste in the sauce . The sauce was put on the stove in a big pot and cooked all day long adding your favorite spices and meat . Sure makes sausage, meatballs , or steak pieces so tender . She would sometimes add a small can of tomato paste if using regular slicing tomatoes . Now available in the organic isles at the store also . Vegetarian sauce can be made with onions, mushrooms , and a few dice carrots . Carrots add a little sweetness if you don’t want to add sugar as some people do.Basil is also sweet. Bon appetite ! Hope I helped a little .

    can these just be canned right after they are done? would you put them in a blender or just leave whole?

      I have never tried canning so I am not sure how they would work for this procedure. I normally use them in recipes right after roasting.
