Panera-style Broccoli Cheddar Soup

I love Panera's broccoli cheddar soup.  I don't think I've ever had anything else from the place, because I crave their soup the minute I get in line to order.  I've tried many broccoli cheddar soup recipes in hopes of replicating Panera, and I finally succeed with this one.  The secret? Nutmeg.

Panera-style Broccoli Cheddar Soup

1/2 medium onion
1/4 cup butter
1/4 cup flour
2 cups milk
2 cups chicken stock
1/2 pound broccoli florets (I have used both fresh and frozen)
1 cup carrots, chopped (Again, I have used both fresh and frozen)
1/4 teaspoon salt
1/4 teaspoon nutmeg
1/2 teaspoon pepper
1 1/2 cup shredded cheddar cheese

1. Melt butter in a medium pot and saute onions until translucent.
2. Add flour and mix well.
3. Slowly add milk, mixing to combine.
4. Slowly add chicken stock, mixing until combined.
5. Let simmer for 10 minutes.
6. Add broccoli and carrots.  Simmer for 20 minutes, or until vegetables are soft.
7. Season with salt, nutmeg, and pepper.
8. Blend soup in a blender or immersion blender until only small chunks remain.
9. Heat soup through and add cheese.

Enjoy!
