5 Star French Onion Soup Stovetop Or Slow Cooker Recipes

Steps:

• Melt butter in a skillet over medium heat. Cook and stir onions in melted butter until clear and browned, 10 to 15 minutes; transfer to a slow cooker. Add beef broth, garlic, salt, and black pepper to the slow cooker.
• Cook on High for 4 hours or on Low for 8 hours.

Steps:

• Heat butter in a large, heavy pot over medium-high heat; cook and stir onions until they become translucent, about 10 minutes. Sprinkle onions with sugar; reduce heat to medium. Cook, stirring constantly, until onions are soft and browned, at least 30 minutes. Stir in garlic and cook until fragrant, about 1 minute.
• Stir sherry into onion mixture and scrape bottom of pot to dissolve small bits of browned food from the pot. Transfer onions into a slow cooker and pour in beef broth. Season to taste with sea salt; stir in thyme and bay leaf. Cover cooker, set on High, and cook 4 to 6 hours. If desired, set on Low and cook 8 to 10 hours.
• About 10 minutes before serving, set oven rack about 8 inches from the heat source and preheat the oven's broiler. Arrange bread slices on a baking sheet.
• Broil bread slices until toasted, 1 to 2 minutes per side.
• Combine Gruyere, Emmental, Parmesan, and mozzarella cheeses in a bowl, tossing lightly. Fill oven-safe soup crocks 3/4 full of onion soup and float a bread slice in each bowl. Top with about 2 tablespoons of cheese mixture per serving.
• Place filled bowls onto a baking sheet and broil until cheese topping is lightly browned and bubbling, about 2 minutes.

Steps:

• Melt the butter in a very large Dutch oven or pot over medium heat. Add the onions, bay leaves, thyme, 1 teaspoon salt, and a few grinds black pepper. Cook, stirring occasionally, until the onions are very soft and light golden-brown, about 1 hour. (The onions will begin to stick to the bottom of the pan and turn brown after about 30 minutes; just keep scraping them up and stirring them into the rest of the onions. If they are browning to quickly, lower the heat.)
• Add the wine to the pot, bring to a simmer and cook until it has almost completely evaporated, about 4 minutes. Add the beef broth and 1 cup of water, bring to a simmer and cook until the flavors come together and the soup is rich, about 45 minutes. Remove the bay leaves. Season with 1/2 teaspoon salt and a few grinds of black pepper. Keep the soup warm on a low burner or cool completely and refrigerate to reheat later. (The soup can be refrigerated for up to 2 days or frozen for up to 1 month.)
• Preheat the broiler. Place four soup crocks on a rimmed baking sheet and fill them about 3/4 of the way with hot soup. Float a slice of baguette on top of each and cover with 1/2 cup Gruyere. Broil until the Gruyere is golden brown (don't be alarmed if some soup bubbles out), 2 to 3 minutes.
