Best 5 Flavorful French Onion Soup Recipes

FRENCH ONION SOUP

Steps:

• In a large Dutch oven or soup pot, melt the butter over medium heat. Add the oil, onions, salt, pepper, and sugar. Cook, uncovered, stirring occasionally with a wooden spoon, until onions are deep golden brown and caramelized, 45 to 55 minutes. In the beginning, you will only need to stir the onions only occasionally. As they start to brown midway through cooking, you will need to stir them frequently, scraping the fond (the brown particles) from the bottom of the pan. If the onions are browning too quickly, reduce the heat slightly or add a few tablespoons of water to deglaze the pan and continue cooking.
• Add the wine and raise the heat to high. Cook, stirring with a wooden spoon to scrape any fond from the bottom of the pan, until almost all of the liquid has evaporated and the onions are jammy, 8 to 10 minutes.
• Add the flour and cook, stirring constantly, for one minute.
• Add the broth, Worcestershire sauce, thyme, and bay leaves to the pot. Bring to a boil, reduce the heat to a simmer, and cook, covered, for about 30 minutes.
• While the soup simmers, preheat the oven to 400°F and set an oven rack in the middle position. Arrange the baguette slices in a single layer on a baking sheet and bake until the bread is dry, crisp, and golden at edges, about 10 minutes. Set aside.
• When the soup is finished, remove the bay leaves and add the sherry; taste and adjust seasoning if necessary. If the soup needs a deeper flavor, try a few shakes of Worcestershire sauce. If it's not quite sweet enough, add ¼ teaspoon sugar.
• Adjust an oven rack 6 inches from broiler element and heat broiler. Set individual broiler-safe crocks on a baking sheet and divide the hot soup among the crocks (be sure the soup is very hot as it won't warm up much in the oven). Top each crock with 1 or 2 baguette slices (do not overlap slices) and sprinkle evenly with Gruyère and then Parmigianno Reggiano. Slide the crocks into the oven and broil until the cheese is melted and bubbly around edges, 3 to 5 minutes. Let the crocks cool for a few minutes before serving. (Alternatively, if using regular soup bowls: Top each toast slice with some cheese and return to broiler to melt, about 2 minutes more. Divide the soup among bowls and top each serving with two cheese toasts.)
• Make-Ahead Instructions: The soup can be made and refrigerated up to 3 days ahead (without toasts or cheese), or up to 3 months ahead and frozen. Toasts can be made (without the cheese) and kept sealed at room temperature for up to 3 days.

Steps:

• Place a heavy-bottom stockpot or dutch oven on a stove over medium-low heat. Add cooking oil and butter. Saute onions until evenly coated with oil and butter.

• Reduce heat to medium-low and stir in the flour. Stir for 2-3 minutes, or until the flour and butter form a thick paste. If paste not achieved, add more butter.

• For the croutons or toasted bread, preheat your oven to 325 degrees F. Drizzle bread with olive oil and place on a baking sheet. Bake the bread for 15 minutes at 325 degrees F. Flip the slices over and bake for another 15 minutes.
• Once the soup has simmered, preheat your oven to 350 degrees F.
• Salt and pepper to taste.
• Pour the soup into a casserole dish. Stir in cognac, the 1/2 raw onion (grated), and a few ounces of Swiss cheese.
• Top the soup with toasted bread in a single layer. Top the bread with the remaining Swiss and Parmesan cheese. Be sure all the edges of bread are covered to avoid burning. Drizzle with oil or melted butter.
• Bake the casserole at 350 degrees F for 30 minutes. Turn on the broiler and brown the cheeses.
• Let the soup cool for a few minutes before serving. Enjoy!
