Making French Onion Soup with Red Onions
Nothing is more comforting than a large, steaming bowl of soup on a chilly day, and this recipe is perfect if you love the taste and aroma of onions. While you can use any type of onion, we prefer red onions with their mild, sweet flavor.
Pour three tablespoons of oil into a pot and add the onions. Cook them on medium heat while stirring for 15 minutes or until softened. Turn the heat to medium-high and add the remaining olive oil and butter. Cook them for 15 more minutes until they start to brown.
Sprinkle sugar and one teaspoon of salt over the onions and cook for ten to 15 more minutes before adding the garlic and cooking one more minute. Deglaze the pot by adding the wine and scraping the brown bits from the bottom and sides of the pan.
Pour the beef stock into the pot and add the bay leaves and thyme. Bring the soup to a simmer, cover and lower the heat, and cook it for about half an hour.
As the soup simmers, brush both sides of the French bread slices lightly with olive oil and bake them for about six minutes in a 450°F oven. Top them with cheese, return them to the oven to bake until the cheese is bubbly, and place one cheesy toast on top of each bowl of soup.
There is nothing quite like the onion flavor of white, yellow, or red onions, and homemade French onion soup and stir fry is not complete without them. However, their oniony taste varies by type, and it’s essential to understand their differences before using them in a side dish.
