Featured Recipe: Sweet Basil’s Onion Soup

I am really excited to be sharing this recipe with you today courtesy of Chef and owner Dave Becker from Sweet Basil located in Needham, MA.
Featuring an ever-changing menu of Italian cuisine with hand-made pastas and ingredients sourced from local New England farms, Sweet Basil has a loyal following of repeat customers who come back time and time again for the quality food and comforting atmosphere.
Chef Dave recently launched his brand new cookbook, Stewed, featuring handmade takes on classic soups, stews, and braises. Using simple fresh ingredients, he builds on flavor and focuses on fundamental cooking techniques.
This kicks off a trio of posts you will find here for the next few Thursday’s that will be focused around Sweet Basil and Chef Dave’s Stewed cookbook. With what seems like never ending cold winter weather what’s a better way to warm up than with some hearty soup recipes?
I hope you enjoy them as much as I do!
