I found this recipe at A Year of Slowing Cooking and it gets two-thumbs up from all three members of our family (including the 8 month-old). It took less than 10 minutes to make. Blending the soup after it has cooled is definitely the way to go! This soup is perfect for a family with a new baby and no time to cook!
--1 qt chicken broth (or vegetable)
--2 cups milk (I used 2% cow's)
--2 10 oz bags of frozen broccoli florets
--1/2 diced white onion
--1/2 t black pepper
--1/2 t kosher salt
--1/2 t ground nutmeg
--1 cup each of three different cheeses, I used jarlsberg, gruyere, and cheddar.
Mince the onion into really small pieces. I used my pampered chef chopper thingy. The onions are going to soften in the milk and the broth, and need to be quite small so you don't crunch on onion pieces when the soup is complete.
Add the onion to your crockpot, and top with the milk, broth, and spices. Stir in the two frozen bags of broccoli.
Cook on low for 7-9 hours, or on high for 4-6. The broth is done when the onion is cooked nicely.
20 minutes or so before serving, shred all the cheese you are going to use, and stir it in. The cheese will be stringy and will stick to the broccoli florets---that's okay!
Serve with your favorite rolls or drop biscuits.
