Slow Roasted Tomatoes and Slow-Roasted Tomato Sauce

This is the first recipe I ever tried for roasting tomatoes several years ago and it’s a good one! But you’ll want to make sure you’ll be home for awhile, because the roasting takes 7 1/2 hours! It’s a great recipe to make on a cold day though, because with all that roasting time, your kitchen will be warm and cozy! You’ll just have to plan ahead a little to give yourself enough time!

The recipe is from a cookbook I reviewed a few years back called The New Way to Cook Light, which is a really nice cookbook by the way, with lots of full-color photos of light and tasty recipes! The Aromatic Slow-Roasted Tomatoes were just calling my name, so that’s what I made for my review post and thought I’d post it again, since we’re in the cold weather time of year.

I really liked these Aromatic Slow-Roasted Tomatoes…slow-roasting tomatoes gives them such a rich flavor, or as the book says, “an intense tomato essence.” I used store-bought tomatoes and was happy with the results, so I can just imagine how wonderful home-grown slow-roasted tomatoes would be! The recipe calls for 1 Tablespoon of sugar to give the tomatoes a light sweetness, and I substituted honey instead and was happy with the result. If you like tomatoes, you’ll want to try this recipe out! And like I said, the only downside is that you’ll need to plan ahead when you are making these, since the tomatoes roast in your oven (at 200˚F) for 7 1/2 hours. But I think it’s definitely worth the  time it takes!

You can serve these tomatoes as a side dish or make Slow-Roasted Tomato Sauce with them—see both recipes below!

I love the rich flavor of these roasted tomatoes. I’m sure you could make great soups with the puree from these, too! Have you tried slow-roasting tomatoes yourself?

    I’m growing a lot of paste tomatoes this summer and this looks like the perfect recipe to make with some. I love a good homemade pasta sauce and roasting for 7.5 hours really sounds like that would intensify the tomato flavor. I can’t wait to try this one out!
