Melt butter in a large pot over medium heat for 2 to 3 minutes or until it begins to brown and gives off a nutty aroma. Add onions, leeks and sugar. Reduce heat to medium-low and cook for 25 to 30 minutes or until vegetables are very soft. Season liberally with lemon pepper. Stir in flour and cook for 2 minutes or until slightly thickened. Add stock and red wine and bring to a boil. Season with salt and pepper to taste. Reduce heat to low and simmer for 10 minutes to combine the Flavors.
Preheat broiler. Mix butter with olive oil and garlic in a small bowl. Spread butter mixture onto each side of the bread. Toast the bread in a pan over high heat or broil each side in the oven.
Divide soup into six oven-safe soup bowls and place on a large baking sheet. Sprinkle lemon zest into each bowl and top with the toasted bread. Combine grated cheese in a medium bowl. Cover toast with grated cheese. Broil for 2 to 3 minutes or until cheese is melted and bubbling.
