I have not done it, but I've saved a GW thread from years ago thinking I would do it:

Wow, email says it was from January 2005. Recipe from Metaxa.

Large roasting pan, fill with tomatoes, onions, celery, whatever you have but don't use too much carrot as you can overpower the sauce.

Drizzle all with balsamic and toss to coat, add S&P, and place in a 350° oven and render unto Caesar.

Poke it every now and then, remove tomato skins as they pop up and when it is a consistency you want for your sauce adjust seasonings.

Gives you a tomato sauce that is redolent of roast vegetable. Don't forget the garlic, just throw in whole cloves.

As an aside, the moisture driven off and the time it takes makes immediately afterwards a good time to clean the oven, everything just slides off or, if you have a self clean, it works better, less residue to wipe out.

Okay. I'm in. Thanks for bringing this up. It sounds like a wonderful option to flavoring my sauces!

This year I have been experimenting with Butternut Squash soup...I may need to actually grow those this year!

I really want to make oven roasted tomato sauce, but I have a tomato growing deficient gene. I want to move next door to Dawn...

In the comments of the link it suggests an electric roaster so you don't heat up the house with the oven. I have one of those and I might try it this summer! I like the idea of not pealing (what a pain) of course I have also read about dehydrating tomato skins and grinding into flavoring powder. Wonder if you could dehydtate what is left in the mill?

I rerun all the tomato puree, including the waste parts, through the mill a couple of times so that the only actual waste I then have left is skin and seeds, Amy. Well, sometimes there's some of the green cores, but I sure wouldn't dehydrate those. If you separate out the seeds (they can have a bitter flavor which is why I tend to remove them anyhow) and have only the skins left, they will dehydrate really fast because there isn't much to them....but then, they also will dehydrate down to practically nothing so you'll have to dehydrate tons and tons of skins to get a decent amount of powder.

Lisa, lol. We just need to fix your tomato gene. As far as I know, neither of our next-door neighbors has any plans to move although I'd love to have you as a neighbor down here.

I'm trying to cut back on how many tomato plants I grow so that I have more room for flowers. The flowers have complained they'd like a whole raised bed all their own because they are tired of being tucked into little spots here and there amongst the vegetables. They're going to get their wish this year. Or, I might sneak in a few veggies or herb plants into the flowers' bed, but they'll be small ones so the flowers can dominate that specific raised bed.

Lisa is a great flower grower, but that would be a long commute. LOL

See how perfect it would be if we were neighbors? I could grow the flowers and you could grow the tomatoes!

Well then, woman, come on down! I'll be the tomato farmer and you can be the flower farmer.
