Ingredients (US Cups & Measurements)
Here’s everything you’ll need to create the ultimate French Onion Beef Short Rib Soup:
For the Soup:
-
2 tablespoons olive oil
-
1 pound bone-in beef short ribs
-
4 large yellow onions, thinly sliced (about 4 cups)
-
4 cloves garlic, minced (about 2 teaspoons)
-
6 cups beef broth (low sodium preferred)
-
1 tablespoon balsamic vinegar
-
1 teaspoon fresh thyme leaves (or ¼ teaspoon dried thyme)
-
1 bay leaf
-
Salt and pepper, to taste
For the Topping:
-
4 thick slices of French bread
-
1 cup shredded Gruyère or Swiss cheese
Equipment You’ll Need
-
Large Dutch oven or heavy-bottomed pot with lid
-
Wooden spoon or spatula
-
Ladle
-
Oven-safe soup bowls
-
Baking sheet for toasting bread
Step-by-Step Directions
1. Sear the Short Ribs
In a large Dutch oven, heat 2 tablespoons of olive oil over medium-high heat. Pat the short ribs dry with paper towels and season them with salt and pepper. Once the oil is shimmering, add the short ribs and sear for 4–5 minutes per side until browned. This step locks in flavor and adds a deep richness to the soup. Once browned, remove the short ribs and set aside.
2. Caramelize the Onions
In the same pot, reduce the heat to medium. Add the sliced onions with a pinch of salt. Cook slowly for 20–30 minutes, stirring frequently. The onions will first soften, then turn golden, and eventually caramelize into a deep brown color. This step is key to developing that signature French onion flavor.
Tip: If the onions start sticking or browning too fast, reduce the heat and add a splash of water to deglaze the pot.
3. Add Garlic and Deglaze
Once the onions are deeply caramelized, stir in the minced garlic and cook for 1–2 minutes. Add the balsamic vinegar to deglaze the pot, scraping up any brown bits from the bottom—these are packed with flavor.
4. Simmer the Soup
Return the short ribs to the pot along with any juices they released. Pour in the beef broth, then add thyme, bay leaf, and a bit more salt and pepper. Bring the mixture to a gentle boil, then reduce to a low simmer. Cover and cook for 1½ to 2 hours, or until the beef is fall-off-the-bone tender.
5. Shred the Beef
Carefully remove the short ribs from the pot and set them aside to cool slightly. Remove the bones and shred the meat using two forks. Discard the bay leaf and return the shredded beef to the soup. Taste and adjust the seasoning as needed.
6. Prepare the Topping
Preheat your broiler. Arrange French bread slices on a baking sheet and toast them under the broiler for 1–2 minutes per side or until golden.
Ladle the hot soup into oven-safe bowls. Place a toasted bread slice on top of each bowl, then sprinkle generously with shredded Gruyère or Swiss cheese.
Place the bowls on a baking sheet and broil for 2–3 minutes until the cheese is bubbly and browned.
7. Serve
Remove carefully (the bowls will be hot!) and serve immediately. Garnish with additional thyme if desired.

Flavor Notes
This soup is all about depth and balance. The sweet onions contrast the savory, umami-rich broth and beef, while the tang of balsamic vinegar adds brightness. Topped with toasty bread and gooey cheese, each spoonful delivers a medley of textures and bold flavors.
Variations
1. Vegetarian Option:
Replace beef short ribs with hearty mushrooms (like portobello or cremini) and use vegetable broth. While it won’t have the same richness, the caramelized onions and cheese still shine.
2. Cheese Swap:
Gruyère is classic, but feel free to experiment with provolone, mozzarella, or even a mix of cheeses like fontina and asiago.
3. Bread Ideas:
Try sourdough, rustic rye, or even garlic bread for a flavor twist.
4. Wine Lovers’ Upgrade:
Deglaze the pot with a splash of dry red wine instead of vinegar for a luxurious finish.
Storage and Reheating Tips
-
Refrigerator: Store soup (without bread and cheese topping) in an airtight container for up to 4 days.
-
Freezer: Freeze soup in containers for up to 3 months. Reheat on stovetop before adding fresh bread and cheese topping.
-
To Reheat with Bread and Cheese: Reheat soup, pour into oven-safe bowl, then top with fresh bread and cheese and broil as instructed.
What to Serve With It
-
Green Salad: A crisp arugula or butter lettuce salad with a citrus vinaigrette balances the richness.
-
Red Wine: Pair with Cabernet Sauvignon or a mellow Pinot Noir.
-
Roasted Veggies: Try garlic-roasted carrots or Brussels sprouts on the side.
-
Apple Slaw: A tangy apple slaw brings a nice crunch and sweetness.
Cooking Tips & Tricks
-
Be patient with the onions. Don’t rush the caramelization; it’s essential for flavor.
-
Use good-quality broth. It forms the base of the soup, so choose a low-sodium, rich beef broth.
-
Deglaze often. Onions leave tasty fond (browned bits) that need to be scraped up to maximize flavor.
-
Let it rest. This soup tastes even better the next day after flavors meld.
-
Cheese technique: For best melt, shred cheese yourself instead of using pre-shredded, which contains anti-caking agents.
Fun Fact: The French Connection
Traditional French onion soup originated in Paris in the 18th century and was popularized as a late-night working-class dish. Adding beef turns it into a more substantial meal fit for any occasion.
