Is it safe? There is no way to know. It is a cooking recipe that someone has tried to convert to a canning recipe but left in the oil and the fresh basil which wouldn't be in a canning recipe.

It is untested so both the density and the pH is unknown and the processing time is just a guess.

It is a do at your own risk recipe.

I'd say with the chicken broth, the garlic and onion, not in a million years. A tablespoon of lemon juice couldn't begin to reduce the pH to a level suitable for BWB.

Besides, assuming the chicken broth is canned, you're canning canned tomatoes and canned broth amended with a few other ingredients, all available year-round except for the fresh basil. And that can be frozen in the summer. In other words, you'd essentially be re-canning, a total waste of your jars, lids and utilities.
