Lightly spray a skillet with nonstick spray.
Cook the beef over medium-high heat for 8 to 10 minutes, or until well-browned.
Stir in the minced garlic, and cook for 1 minute.
Pour the beef broth and red wine into a large measuring cup. Whisk in the cornstarch.
Pour the broth-wine-cornstarch mixture into the skillet. Scrape up any browned bits that have accumulated at the bottom of the pan. Bring to a boil over medium-high heat.
When the mixture boils, add the thawed pearl onions, and turn the heat down to medium-low. Cover the skillet with a lid and simmer for 15 to 20 minutes or so.
Stir in the black pepper and chopped parsley.
