spoonful of Roasted Garlic Tomato Basil Soup

Growing up I’ve never been a fan of canned tomato soup.

In fact, I actually didn’t start liking tomato soup until years ago when I began making it myself. Go figure.

It has been on and off soup season here in Michigan. So far, our fall weather has been incredible. We’ve had so much sunshine, mild/warm temps peppered with some crisp cool days and evenings. Most years, my basil plants last until mid to late September. However this year, it lasted through most of October – which has been such a blessing. I quite literally just pulled my basil plants from my herb garden this past weekend. But before doing so, I made this incredible soup.
