Beef Stock For French Onion Soup Recipes

Steps:

• Preheat oven to 400 degrees. Arrange beef bones and oxtail in a single layer in a heavy roasting pan (not glass). Coat with oil. Roast, turning once, until deep brown, about 45 minutes.
• Add tomato paste, onions, leeks, celery, carrots, and garlic, stirring well. Roast until vegetables are browned and tender, about 40 minutes.
• Meanwhile, make a bouquet garni by wrapping parsley, thyme, bay leaves, and peppercorns in a square of cheesecloth. Tie bundle with kitchen twine; set aside.
• Transfer bones and vegetables to a large stockpot; set aside. Pour off fat from roasting pan. Set pan on stove across two burners. Add wine, and bring to a boil, deglazing pan by scraping up any brown bits from bottom with a wooden spoon; boil until wine is reduced by half, about 3 minutes. Add to stockpot.
• Add 6 quarts (24 cups) water to stockpot. Bring to a boil. Reduce heat; bring to a gentle simmer. Add bouquet garni. Simmer, uncovered, over low heat, 3 hours.
• Carefully pass stock through a fine sieve into a large bowl or pot; discard solids. Let stock cool completely.
• Transfer stock to airtight containers. Refrigerate at least 8 hours or up to 3 days before using (fat will solidify; discard it before using). The stock can be frozen up to 4 months.

Steps:

• Mix flour, 2 tablespoons salt, 1 tablespoon black pepper, paprika, garlic powder, and onion powder in a bowl. Dredge beef short ribs in the seasoned flour mixture. Reserve 3 tablespoons of leftover seasoned flour.
• Heat olive oil in a large pot over medium-high heat and pan-fry the beef ribs until browned on all sides, 3 to 5 minutes per side. Remove ribs and set aside. Turn heat down to medium and melt butter in the pot; cook and stir sweet onions in the butter until soft and slightly browned, about 15 minutes. Stir constantly and reduce heat if onions begin to burn.
• Stir 3 tablespoons of reserved seasoned flour mixture into the onions and cook and stir for 10 minutes; pour in beef broth and sherry. Bring to a boil, stirring constantly, until soup is slightly thickened; season with more salt and black pepper, if desired.
• Strip leaves from thyme sprigs and add leaves to the soup. Gently return short ribs to the pot, reduce heat to low, and simmer soup until ribs are tender, about 2 1/2 hours. Stir soup every hour or so.
• Preheat the oven's broiler.
• Ladle soup into oven-safe soup crocks, placing a short rib into each bowl. Top soup with 2 slices of French bread per bowl and sprinkle about 1/4 cup of Gruyere cheese over each crock.
• Place crocks under broiler until cheese is browned and bubbling, 2 to 3 minutes.
