Melt butter with olive oil in an 8 litre or similar sized stock pot on medium heat. Add onions and continually stir until tender and translucent. Do not brown the onions.
Add beef stock, sherry and thyme. Season with salt and pepper and simmer for 30 minutes.
Preheat the grill.
Ladle soup into oven-safe serving bowls and place one slice of bread on top of each (bread may be broken into pieces if you prefer). Layer each slice of bread with a slice of mozzarella, 1/2 slice diced Gruyere and 1 tablespoon Parmesan cheese. Place bowls on baking tray and grill until cheese bubbles and browns slightly.
