Ingredients

For the Beef Short Ribs:

  • 2 to 3 pounds of bone-in beef short ribs
  • Salt and black pepper to taste
  • 2 tablespoons olive oil
  • 1 large onion, roughly chopped
  • 2 carrots, roughly chopped
  • 2 celery stalks, roughly chopped
  • 4 cloves garlic, smashed
  • 2 tablespoons tomato paste
  • 1 cup red wine (optional but recommended)
  • 6 cups beef broth or stock
  • 2 sprigs of thyme
  • 1 bay leaf

For the Caramelized Onions:

  • 4 to 5 large yellow onions, thinly sliced
  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • Salt to taste
  • 1 teaspoon sugar (optional, helps caramelize)
  • 1/2 cup dry white wine or beef broth (to deglaze)

For Assembly:

  • Slices of crusty baguette or rustic bread
  • 1 to 2 cups grated Gruyère or Swiss cheese
  • Chopped parsley or thyme for garnish (optional)

Instructions

Step 1: Prepare the Short Ribs

  1. Pat the short ribs dry using paper towels. Season generously with salt and black pepper on all sides.
  2. In a large Dutch oven or heavy-bottomed pot, heat the olive oil over medium-high heat.
  3. Sear the short ribs in batches until browned on all sides, about 2 to 3 minutes per side. Remove and set aside.
  4. In the same pot, add the chopped onions, carrots, and celery. Cook for 5 to 6 minutes, stirring occasionally, until softened.
  5. Add garlic and cook for 1 minute more.
  6. Stir in the tomato paste and cook for 2 to 3 minutes to caramelize it slightly.
  7. Deglaze the pot with red wine, scraping the bottom to release all the flavorful bits. Let it reduce by half.
  8. Return the short ribs to the pot. Add the beef broth, thyme, and bay leaf. Bring to a simmer.
  9. Cover and braise in a 325°F (160°C) oven for 2.5 to 3 hours, or until the meat is fall-off-the-bone tender.

Step 2: Caramelize the Onions

  1. While the short ribs are cooking, prepare the caramelized onions.
  2. In a large skillet or sauté pan, melt the butter with the olive oil over medium-low heat.
  3. Add the sliced onions and a pinch of salt. Stir to coat in the fat.
  4. Let the onions cook slowly, stirring occasionally, for 45 to 60 minutes, until they become deeply golden brown. If they dry out too much, add a splash of water.
  5. If desired, sprinkle the onions with a teaspoon of sugar after 30 minutes to enhance browning.
  6. Deglaze the pan with wine or beef broth to lift all the browned bits. Set aside.

Step 3: Shred the Short Ribs

  1. When the short ribs are fully cooked and tender, remove them from the braising liquid.
  2. Let them cool slightly, then remove the bones and shred the meat using two forks.
  3. Skim the fat from the surface of the broth if needed. Strain out the vegetables and discard them.
  4. Return the shredded meat to the pot and add the caramelized onions. Simmer gently for 10 to 15 minutes to allow the flavors to meld.

Step 4: Assemble and Serve

  1. Preheat the broiler in your oven.
  2. Ladle the soup into oven-safe bowls or ramekins.
  3. Top each bowl with a slice of crusty bread and a generous amount of grated cheese.
  4. Place under the broiler until the cheese is bubbly and golden, about 2 to 4 minutes. Watch carefully to avoid burning.
  5. Garnish with chopped parsley or thyme if desired and serve hot.

Tips for Success

  • Use bone-in short ribs for maximum flavor and richness.
  • Caramelizing the onions slowly is key to achieving that deep, sweet onion flavor that defines French onion soup.
  • Skim fat off the broth to avoid an overly greasy texture.
  • Use a high-quality cheese that melts well, like Gruyère, Emmental, or Fontina.
  • If you do not have oven-safe bowls, you can toast the bread separately with cheese and float it on top of the soup before serving.

Make Ahead and Storage

Make Ahead:
This soup is ideal for making in advance. The flavors deepen after a day or two. Prepare the soup as directed, refrigerate, and reheat before serving. Toast the bread and melt the cheese fresh for best results.

Storage:
Store leftovers in airtight containers in the refrigerator for up to 4 days. Reheat gently on the stove.

Freezing:
You can freeze the soup (without the bread and cheese topping) for up to 3 months. Thaw overnight in the fridge and reheat before serving.

Variations

  • Add Mushrooms: For added umami, sauté mushrooms and stir them into the soup before serving.
  • Use Different Meats: Try using oxtails, chuck roast, or even lamb shanks instead of short ribs.
  • Gluten-Free Option: Use gluten-free bread or omit the bread entirely and serve with a side salad.
  • Low-Carb Option: Skip the bread and simply melt cheese directly onto the soup for a keto-friendly version.
  • Spicy Twist: Add crushed red pepper flakes or a splash of hot sauce for a slight kick.
