Broccoli Cheese Soup

I found this one night when I was craving broc/cheese soup and it turned out to be really good, and really EASY...always one of my prerequisites!

6 Tablespoons butter
1 onion (chopped)
1 (16 oz) pacakge frozen broccoli
4 (14.5 oz.) can chicken broth
1 (1lb) loaf Velveeta (cubed)
2 cups whole milk
1 clove fresh garlic (or more if you are like me and LOVE garlic!)
2/3 cup cornstarch (or flour)
white pepper

Directions:
In a stockpot, melt butter over medium heat. Cook onion in butter until softened. Add garlic just before broccoli. Stir in broccoli and cover with 3 cans chicken broth. Simmer until broccoli is tender, 10-15 minutes.

Reduce heat and stir in cheese cubes until melted. Mix in milk.

In a small bowl, stir cornstarch (or flour) into last can of chicken broth until dissolved. Stir into soup; cook, stirring frequently, until thick.
