French Onion Short Rib Soup

French Onion Short Rib Soup with Gruyère Toast brings two timeless comfort dishes together and lifts them with the lush flavor of slow-cooked beef and sweet caramelized onions. This is the kind of recipe that fills your kitchen with rich aromas and produces the kind of cozy meal you want to savor slowly at the end of a chilly day.

The first time I made this, family gathered around the table for seconds before I could even sit down. Now it gets requested any time the weather turns cold and craving comfort hits.

Ingredients

• Salted butter: Rich flavor base that helps softly caramelize the onions for sweetness
• Yellow onions: Thinly sliced yellow onions stewed low and slow add deep sweetness Choose firm onions with dry papery skins
• Black pepper: A gentle amount balances the natural sweetness Use freshly cracked for best aroma
• Shallots: Adds another layer of mild onion flavor with a hint of garlic Good quality shallots feel heavy for their size
• Fresh thyme leaves: Gives the soup classic herbal complexity Pick sprigs with vivid green leaves
• Fresh sage: Adds a subtle earthy note Look for soft unblemished leaves
• Red chili flakes: Brings gentle heat Adjust for your spice comfort
• Low sodium chicken broth: Lightly seasoned to let the beef shine Use homemade or a high-quality boxed version
• Tamari or low sodium soy sauce: Adds umami and depth Tamari has a smoother flavor with less salt
• Bone-in beef short ribs: The star ingredient imparts richness and body to the broth Look for well-marbled pieces
• Bay leaves: Infuses the soup with floral and herbal undertones
• Star anise: Optional but provides a unique delicate backnote Choose whole pieces that are deeply fragrant
• Baby carrots: Sweet bursts of color and flavor Go for crisp small carrots
• French bread: The traditional French onion soup topper Slices should be hearty and a day old to stand up in the broth
• Gruyère cheese: Classic for melting salty nutty cheese Choose a block you can shred yourself for better melt

Instructions

Melt the Butter and Caramelize the Onions:

Melt the salted butter in a heavy oven-safe Dutch oven over medium-high heat Add the thinly sliced onions Stir occasionally while cooking for roughly ten minutes letting them soften and start to turn golden If you see lots of brown stuck bits scrape the pot to build that flavor base

Build Flavor with Aromatics:

Add sliced shallots chopped garlic fresh thyme leaves chopped sage and a pinch of red chili flakes Stir for two to three minutes until the mixture becomes very fragrant and the herbs look wilted

Brown the Short Ribs and Add Liquids:

Nestle bone-in beef short ribs right into the onions Pour in the chicken broth starting with six cups but keeping more ready if you prefer it soupier Add tamari bay leaves and drop in star anise if using Gently stir to make sure nothing sticks

Braise in the Oven:

Cover the Dutch oven with a tight lid and transfer to a preheated 325 degree oven Let it braise for two and a half to three hours You want the short ribs so tender they fall away from the bone Check after two hours and add the baby carrots so they finish sweet and just fork-tender

Shred the Beef and Simmer:

Remove the pot from the oven Carefully fish out bay leaves and star anise Discard the bones and shred the beef with two forks Return shredded meat to the pot over low heat Taste to check seasoning and adjust with salt or pepper if needed

Make Gruyère Toast:

Heat the oven to 425 degrees Slice French bread thick and set onto a baking sheet Toast for about ten minutes until the bread is lightly crisp Switch to broil Sprinkle thick shredded Gruyère on each slice and broil for two or three minutes until cheese is bubbling and browned at the edges

Assemble and Serve:

Ladle rich soup into deep bowls Float a slice of the cheesy Gruyère toast right on top Garnish each serving with fresh thyme and an extra crack of black pepper if you like

Short ribs are my top pick because every spoonful is meltingly tender and deeply flavorful You get the kind of broth that draws everyone to the kitchen just from the aroma For us the best part is the cheese toast I never saw a crumb left on any plate

Storage Tips

Store leftover soup in airtight containers in the refrigerator for up to four days For longer storage freeze in individual portions in freezer safe bags Do not freeze the cheesy toasts Instead toast fresh when ready to serve again Reheat soup gently on the stove until hot and bubbly

Ingredient Substitutions

No short ribs Try stew beef or even a chuck roast cut into thick pieces Swap Gruyère with Swiss or Comté for slightly different but still delicious results Vegetarian friends can substitute hearty mushrooms and a splash of good mushroom broth for the beef

Serving Suggestions

Serve the soup with more fresh thyme and a simple green salad for contrast The rich broth pairs especially well with a bright vinaigrette You can even cut the toasts smaller for appetizer style mini bowls

Success Stories

Recipe FAQs

The long simmering time with bone-in short ribs, caramelized onions, and fresh herbs builds a deeply savory, satisfying profile.

→ Can I use a different cheese instead of Gruyère?

Yes, Swiss or Emmental are suitable alternatives, but Gruyère gives the toast its signature nutty taste.

Absolutely. The soup base can be made ahead and gently reheated before serving with freshly broiled toast.
