This Creamy Broccoli Cheese Soup is a comforting cheesy dish full of delicious low-carb, keto-friendly nutrition to enjoy all year round.

The secret to this cheddar cheese soup is roasting the broccoli, which gives a rich caramelized flavor adding depth and character to the dish.
You can forgo the roasting, but in my opinion, the extra time is worth the added flavor.
