Instructions

  1. Heat oil or butter in a pot. Sauté onion until soft, then add garlic and cook for 1 minute.

  3. Blend until smooth using an immersion or regular blender. Stir in cream if desired, and adjust seasoning.
  4. Preheat broiler or oven to 400°F (200°C). Toast bread lightly on one side.

  6. Top toasted side with onions and cheese. Broil until bubbly and golden.
  7. Serve soup hot with cheese toast on the side or dipped in.

Notes

  • Use roasted red peppers or red pepper flakes for a spicier soup.
  • Caramelized onions add extra depth to the toast.
  • Try different cheeses like Gruyère or mozzarella.
  • Add croutons or cooked pasta for a heartier soup.
