Canning Ratatouille

In the years when I am lucky enough to have zucchini, eggplant and tomatoes all come in at the same time I make sure that I get busy canning ratatouille. This classic French vegetable stew is of one of our favorite meals here on the farm and I love to be able to taste this famous summer meal all winter long. I use is as a sauce for pasta, a base for soup and an add in for risotto. It’s a delightful addition to the pantry for a quick meal if I’m not feeling well – the hubby can just grab a jar and heat it up.

How is the Canned Ratatouille?

It is admittedly, not as good as fresh or the Roasted Ratatouille I make when I have the ingredients on hand but it is very good. When I heat it up the flavors all come together beautifully. Since I don’t fully cook the vegetables they still have a bit of texture although it is mostly towards the skin end. The eggplant to some degree melts into the sauce to make it very rich tasting and the bright tomato flavor does stay.
