Making Broccoli Cheddar Cheese Soup

My vegetarian daughter is visiting this week from the frozen tundra. Somehow we were talking about either going to a restaurant or eating at home.  Broccoli cheddar cheese soup was brought up in the conversation and the restaurant idea could wait until tomorrow.

Having never made it before, I searched for recipes.  I decided to take bits and pieces from 3 or 4 recipes and see what happens. Specifically Serious Eats, since I have his new cookbook, The Food Lab.  Also America’s Test Kitchen, Averie cooks, and The Girl Who Ate Everything.

The first time I made it, (I made it two days in a row), the technique was bad or the cheese misbehaved.  I used whole milk and straight cheddar cheese. I think I overcooked the milk and it started to separate and turned a little grainy. It may have also been due to using straight sharp cheddar and not mixing in some good quality American cheese for smoothness, as Serious Eats recommended.

On the second day, I mixed in some American cheese and used half and half rather than whole milk and added it at the very end so I knew it wouldn’t get overcooked.  This turned out fantastic…smooth, creamy, and delicious.

A Lodge 6 quart Dutch Oven is perfect for making this soup. Get yourself one for your birthday if you don’t have one already.

To properly cook all the parts of the broccoli, I separated the stems from the very tops of the florets so they could cook longer to soften. Once the stems, onion, carrot, and celery were cooked some, I used the immersion blender to break down the veggies in the vegetable broth. 

This seemed to intensify the broccoli flavor. To use all the thick broccoli stems, use a vegetable peeler to remove the thick skin and get down to the softer flesh. Then chop it into 1/2 inch pieces.

Give this recipe for vegetarian broccoli cheddar cheese soup a try while it is still kind of cold out. It’s satisfyingly good.
