Preparation
Step 1
Heat oil in large saute pan. Add onions and cover -- cook onions until they are very tender, approx. 10 minutes. Uncover, turn up heat, and cook onions until they are a rich, mahogany brown, about 10 minutes or longer. Stir every 2 to 3 minutes and do NOT burn.
Place onions in slow cooker with beef stock. Cover and cook on low for 4 to 6 hours.
Add vermouth. Place soup in soup bowls. Top each bowl with a slice of French Bread; sprinkle with a mixture of Swiss and Parmesan cheeses.
Place under the broiler just until cheese melts. Serve AT ONCE.
