Cook Techniques
Sautéing
Start by heating olive oil in a large stock pot. Add chopped onions, celery, and minced garlic to the hot oil, and sauté until the onions become translucent. This process enhances the flavor base of the soup.
Simmering
After adding all the ingredients, bring the soup to a boil. Once boiling, reduce the heat and cover the pot to let it simmer. This slow cooking technique allows the flavors to meld and ensures the ingredients are cooked through.
Seasoning
Once the soup is finished simmering, taste it and add salt and pepper according to your preference. Proper seasoning elevates the overall flavor profile of the dish.
Serving
Serve the soup hot, ideally with crusty bread on the side. This adds texture and makes for a hearty meal.
