Canning roasted tomatos. I like to roast tomatos slowly in the oven, using olice oil,garllc and fresh thyme. Would it be safe to process these in a hot water bath, or because of the use of olive oil, should I pressure can them? Thanks for your advice.

Thank you for your question. Because you are likely not following a recipe that has been research-tested for canning safety, I would recommend that you freeze your tomatoes instead.

If you want to can your tomatoes, please refer to the National Center for Home Food Preservation or our OSU Extension Fact Sheets for Canning Tomatoes and Canning Tomato Products.
