Assemble the Toast
Place the slices of crusty bread on a baking sheet. Layer each slice with a few thinly sliced onion rounds, followed by a generous sprinkling of shredded cheddar cheese.
Broil to Perfection
Slide the baking sheet under the broiler and cook for 3–5 minutes, keeping a close watch to avoid burning. The cheese should melt completely, bubbling and turning a beautiful golden brown.
3. Serving the Dish
Plate the Soup and Toast
Ladle the hot tomato soup into individual bowls and, if desired, garnish with freshly chopped parsley or chives for a pop of color and added freshness. Serve alongside the cheese and onion toast, either on the side or partially dipped in the soup for a hearty presentation.
