Pro Tips from My Kitchen
Want to amp up the flavor? Double the roasted garlic. For my vegan friends swap in your favorite plant butter it works just as well. When cooking for a crowd just double or triple everything and blend in batches. If you like your mash with more texture use an immersion blender instead of the food processor.

Frequently Asked Questions
