Garlic soup is a deeply rooted traditional dish in Spanish cuisine, known for its comforting flavor and its use of basic ingredients like garlic and bread. Its origin dates back to medieval times, when it was mainly consumed by peasants who used humble and accessible ingredients. In Latin America, this soup may have different names or variations depending on the country; for example, in Mexico it is commonly known as "caldo de ajo" and in other places, ingredients like egg or chilies are added to give it a distinctive touch. Although the basic recipe is simple, each region adapts this classic to reflect its own culinary traditions.
This dish is valued not only for its flavor but also for its digestive and energetic properties, as garlic is recognized for its health benefits. Over time, garlic soup has evolved, incorporating modern techniques and ingredients to make it lighter and suitable for low-fat diets, as is the case with this version with roasted onion that intensifies the flavor without adding unnecessary calories.
