Panera Broccoli Cheddar Soup is probably one of the most sought after copycat recipes. Rightfully so, because it is everything that is good in the world - thick, creamy, cheesiness, with the right amount of health from green broccoli.
Prepare the roux: In a large pot on medium heat, melt your butter. Once the butter is melted, add in the flour and continue to stir to cook through the flour. This should take 1-2 minutes.
Add the Vegetables: Add the chicken broth to the pot, stirring well to incorporate the flour mixture. Add the broccoli and shredded carrots, and let it simmer over medium heat until the broccoli is tender.
