Ingredients

For the Soup:

  • 2 tablespoons olive oil
  • 1 pound beef short ribs
  • 4 large onions, thinly sliced
  • 4 cloves garlic, minced
  • 6 cups beef broth (low-sodium recommended)
  • 1 tablespoon balsamic vinegar
  • 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme)
  • 1 bay leaf
  • Salt and pepper to taste

For the Topping:

  • 4 slices French bread or baguette
  • 1 cup shredded Swiss or Gruyère cheese

Instructions

Step 1: Sear the Short Ribs

Begin by heating olive oil in a large soup pot or Dutch oven over medium heat. Season the short ribs generously with salt and pepper. Add them to the pot and sear on all sides—this takes about 4–5 minutes per side. You want a rich brown crust for maximum flavor. Once seared, remove the short ribs and set aside.

Step 2: Caramelize the Onions

In the same pot, add the sliced onions. The fond (brown bits left behind by the meat) adds incredible depth to the flavor. Cook the onions over medium-low heat, stirring occasionally, for about 15–20 minutes until they become golden brown and caramelized. This step is key to achieving that signature French onion soup flavor.

Step 3: Add Garlic and Deglaze

Stir in the minced garlic and cook for an additional 1–2 minutes, just until fragrant. Be careful not to let the garlic burn.

Deglaze the pan by pouring in the balsamic vinegar and scraping the bottom of the pot to release any remaining bits of flavor. Let the mixture simmer for a minute.

Step 4: Simmer the Soup

Return the seared short ribs to the pot. Add the beef broth, thyme, bay leaf, and more salt and pepper to taste. Stir to combine.

Bring the soup to a gentle boil, then reduce heat to low. Cover and let it simmer for 1.5 to 2 hours. During this time, the short ribs will become fall-apart tender and the broth will deepen in flavor.

Step 5: Prepare the Bread

While the soup is simmering, preheat your oven broiler. Arrange the French bread slices on a baking sheet and toast them lightly on both sides. This gives them enough structure to hold up in the soup and resist getting too soggy.

Step 6: Shred the Meat

Once the ribs are fully cooked and tender, remove them from the pot. Discard the bones and shred the meat using two forks. Return the shredded beef to the soup and stir well. Discard the bay leaf at this point.

Taste and adjust seasoning as needed.

Step 7: Assemble and Broil

Ladle the soup into oven-safe bowls. Place a slice of toasted French bread on top of each bowl. Sprinkle a generous handful of shredded Swiss or Gruyère cheese on top.

Place the bowls under the broiler for 2–3 minutes, or until the cheese is melted, bubbly, and golden brown. Watch closely to avoid burning.

Step 8: Serve and Enjoy

Carefully remove the bowls from the oven (they will be hot). Let them sit for a minute or two before serving. The aroma alone is enough to make your mouth water.

Tips for Recipe Success

  • Choose the right pot: A heavy Dutch oven retains heat well and caramelizes onions beautifully without burning them.
  • Be patient with the onions: Don’t rush the caramelization process—low and slow is best for sweet, golden results.
  • Use high-quality broth: Since this is a broth-based soup, a good-quality beef stock makes a big difference.
  • Shred beef finely: The smaller pieces of short rib blend better into the soup and give you more even bites.
  • Melt cheese carefully: Don’t walk away from the broiler—cheese goes from golden to burnt in seconds.

Serving and Storage Tips

Serving Suggestions:

  • Pair this soup with a crisp green salad for a complete meal.
  • A glass of red wine like Cabernet Sauvignon or Merlot complements the deep, beefy flavor.
  • Add sautéed mushrooms for an earthy, savory touch.

Storage Instructions:

  • Refrigerator: Store any leftovers in an airtight container for up to 4 days. Store bread and cheese separately to prevent sogginess.
  • Freezing: Freeze the soup without the bread and cheese for up to 3 months. Thaw in the refrigerator overnight before reheating.
  • Reheating: Warm the soup gently on the stovetop. Add fresh toasted bread and shredded cheese before broiling again for that fresh-from-the-oven feel.

Frequently Asked Questions

1. Can I use boneless short ribs instead of bone-in?

Yes, boneless short ribs will work just fine. You may lose a bit of bone-derived flavor, but the dish will still be incredibly rich and delicious.

2. What if I don’t have oven-safe bowls?

If you don’t have bowls that can go under the broiler, you can broil the bread and cheese separately on a baking sheet and place it on top of the soup just before serving.

3. Can I substitute another cut of beef?

Chuck roast or stew meat can work in a pinch, though short ribs have the best texture and richness for this type of soup.

4. What kind of onions should I use?

Yellow onions are the traditional choice for French onion soup. They caramelize beautifully and have a perfect balance of sweet and savory.

5. Can I make this recipe in a slow cooker?

Yes. After searing the meat and caramelizing the onions, transfer everything to a slow cooker and cook on low for 6–8 hours. Shred the meat and finish under the broiler as usual.
