Ingredients You’ll Need
-
900 g (2 lbs) beef short ribs, cut into pieces
-
3 large yellow onions, thinly sliced
-
1.4 L (6 cups) beef broth, preferably homemade
-
2 tsp fresh thyme leaves
-
2 bay leaves
-
4 slices of sourdough bread
-
100 g (1 cup) Gruyère cheese, shredded
-
28 g (2 tbsp) unsalted butter
-
Salt and black pepper to taste
Step-by-Step Directions
-
Caramelize the onions: In a large pot, melt the butter over medium heat. Add onions and cook for 25–30 minutes, stirring often, until golden brown and deeply caramelized.
-
Sear the beef short ribs: Push onions to one side. Add short ribs, searing on all sides for 5–7 minutes until browned.
-
Build the soup base: Pour in the beef broth, then add thyme and bay leaves. Stir, bring to a gentle boil, then reduce the heat to low. Simmer uncovered for about 2 hours, until the ribs are fall-apart tender.
-
Prepare for the cheesy finish: Preheat oven to 350°F (175°C). Remove bay leaves. Ladle soup into oven-safe bowls.
-
Add the topping: Place a slice of sourdough bread over each bowl and top generously with shredded Gruyère.
-
Bake to perfection: Transfer bowls to the oven and bake for 15–20 minutes, until the cheese is bubbly and golden.
-
Serve hot: Let cool slightly (cheese is basically lava at this stage), then serve with extra sourdough on the side.

Cooking Tips for the Perfect Soup
Caramelizing onions takes patience—don’t rush it. Low and slow heat is what develops that sweet, golden magic. If they start sticking, just add a splash of broth or water. When searing the ribs, make sure your pan is hot enough to get that deep brown crust; that’s where the flavor lives.
If you don’t have oven-safe bowls, you can transfer everything to a baking dish, lay the bread and cheese on top, and scoop out portions afterward—less dramatic presentation, but the same irresistible flavor. And while Gruyère is the classic choice for French onion Gruyère soup, you can experiment with Swiss or even provolone if that’s what you have on hand. (I won’t tell the French.)
A Personal Note from My Kitchen
This soup became a staple in my house after one particularly frosty evening when my kids insisted cereal would be “just fine for dinner.” I knew better. I had short ribs waiting in the fridge and a craving for caramelized onion soup. Two hours later, the house smelled like heaven—rich, savory, with that sweet onion aroma drifting from the kitchen. By the time I pulled the bubbling bowls from the oven, even the picky eaters were hovering like hawks. And let me tell you, not a single spoonful was left.
Now it’s my go-to comforting dinner idea whenever the temperatures dip or I just need a little edible hug in a bowl.
What to Serve with French Onion Beef Short Rib Soup
This soup is already hearty, but a crisp green salad makes a nice fresh contrast. Think simple arugula with lemon vinaigrette or a classic Caesar. If you’re leaning into cozy vibes, serve with roasted root vegetables or mashed potatoes on the side. A glass of red wine (Cabernet or Pinot Noir) pairs beautifully with the beefy richness, while sparkling water with a squeeze of lemon keeps things light.
For a special dinner, I like to round it out with something sweet but not heavy, like a lemon tart or chocolate mousse. Because let’s be honest—if you’ve just baked a bubbling bowl of French onion Gruyère soup, you’ve earned dessert.
How to Store Leftovers
If you’re lucky enough to have leftovers, let the soup cool completely before refrigerating. Store it in an airtight container for up to 3 days. The flavors deepen overnight, making it even better the next day.
To reheat, gently warm the soup on the stovetop. If you want the cheesy bread topping again, ladle the hot soup into oven-safe bowls, add fresh bread and cheese, then broil until bubbly. You can also freeze the soup (without the bread and cheese) for up to 3 months. Just thaw overnight in the fridge before reheating.
FAQs
Can I substitute the short ribs?
Yes! Chuck roast or stew beef works well, though short ribs give the richest flavor.
Can I make this ahead of time?
Absolutely. The soup base can be made a day in advance. Just reheat, top with bread and cheese, then bake before serving.
What if I don’t have Gruyère?
Swiss cheese, provolone, or even mozzarella can step in. The flavor will be slightly different but still delicious.
Can I make it vegetarian?
Yes! Swap short ribs for mushrooms and use vegetable broth. You’ll still get that deep, savory flavor with the caramelized onions.

Take your time caramelizing the onions—low and slow brings out their natural sweetness.
If you don’t have oven-safe bowls, assemble bread and cheese in a baking dish, then portion out after baking.
Gruyère is classic, but Swiss or provolone work as substitutes.
Make the soup base a day ahead and add the bread and cheese topping before serving.
Leftovers taste even better the next day.
