Twelve ingredients and about three and a half hours, most of it hands-off.
Two slow processes happen in the same pot: the onions caramelise first, then the short ribs braise in the broth until they shred.
Why This Recipe Works
- Browning the short ribs first gives the broth its dark, beefy depth.
- Caramelising the onions slowly in the same pot picks up everything the beef left.
- A long, gentle simmer turns short rib tender enough to shred.
- Shredding the beef back into the broth spreads it through every spoonful.
- A thick slice of toast spanning the crock holds the Gruyère up to brown.
Ingredient Notes
- Boneless beef short ribs
- Two pounds, browned first and braised until they shred. The shredded beef is visible under the toast.
- Yellow onions, thinly sliced
- Four large ones, cooked 35 to 45 minutes. They shrink dramatically as they caramelise.
- Thick rustic bread and Gruyère
- Six slices and a cup and a half. One toasted slice spans each crock and carries the cheese.
How to Make It
Short ribs seasoned and browned, set aside
Season short ribs with salt and pepper. Brown in oil in a heavy pot over medium-high, then transfer to a plate.
Onions cooked in butter until deeply caramelised
Lower heat to medium, add butter and onions, and cook 35 to 45 minutes until deeply caramelized.
Garlic, broth, Worcestershire, thyme and the ribs added
Add garlic for 30 seconds, then broth, Worcestershire, thyme and browned short ribs.
Simmered two to two and a half hours, shredded, returned
Cover and simmer gently 2 to 2 1/2 hours until the beef is fully tender and shreds easily; remove the ribs, shred, and return the meat to the broth.
Ladled into crocks, topped with toast and Gruyère
Ladle soup into broiler-safe crocks. Top each with one thick toasted bread slice and Gruyère.
Broiled until the cheese is browned, thyme over
Broil 1 to 3 minutes until the cheese is melted and browned; finish with thyme leaves.
Three Slow Stages and a Fast One
This soup is built in one heavy pot across nearly three and a half hours, and each stage depends on the one before. The beef browns, the onions caramelise in what it leaves, the beef braises in the onion broth until it shreds - and then a minute or two under the broiler turns it into French onion soup.
Stage 1 of 4
BROWN the short ribs
Steps 1–1 of 6
2 lb of BONELESS BEEF SHORT RIBS seasoned with 1 tsp SALT and 1/2 tsp PEPPER and BROWNED IN 1 tbsp OIL in a HEAVY POT OVER MEDIUM-HIGH, then set aside. The browned bits left in the pot are the start of the broth's colour.

Stage 2 of 4
CARAMELISE the onions - 35 to 45 minutes
Steps 2–2 of 6
Heat LOWERED TO MEDIUM, 2 tbsp BUTTER and 4 LARGE THINLY SLICED YELLOW ONIONS COOKED UNTIL DEEPLY CARAMELIZED. Deeply is the endpoint, and it cannot be hurried - the onions' sugars brown slowly, and they lift the beef's browned bits from the pot as they release moisture.

Stage 3 of 4
BRAISE until it shreds - 2 to 2 1/2 hours
Steps 3–4 of 6
2 MINCED GARLIC CLOVES for 30 SECONDS, then 6 cups LOW-SODIUM BEEF BROTH, 1 tsp WORCESTERSHIRE, 4 THYME SPRIGS and the browned ribs, COVERED AND SIMMERED GENTLY UNTIL THE BEEF IS FULLY TENDER AND SHREDS EASILY. The ribs are then shredded and RETURNED TO THE BROTH. For safety, whole-cut beef must reach AT LEAST 145°F PLUS A 3-MINUTE REST, and THIS BRAISE CONTINUES WELL BEYOND THAT UNTIL SHREDDABLE.

Stage 4 of 4
The CROCK and the BROIL - 1 to 3 minutes
Steps 5–6 of 6
Soup LADLED INTO BROILER-SAFE CROCKS, each TOPPED WITH ONE THICK TOASTED BREAD SLICE - one of the 6 thick slices of rustic bread - and some of the 1 1/2 cups of SHREDDED GRUYÈRE, then BROILED UNTIL THE CHEESE IS MELTED AND BROWNED and FINISHED WITH THYME LEAVES. One slice spanning the crock mouth, rather than croutons floating in the broth. Broiler-safe crocks only, HANDLED AS EXTREMELY HOT.

Success Tips
- Don't rush the onions — deep brown is where the flavour comes from.
- Scrape the pot as the onions release moisture to lift the browned bits.
- Use only broiler-safe crocks, and move them with thick oven mitts.
Serving Ideas
Six crocks of dark French onion broth with caramelised onions and shredded short rib, each under a thick slice of toast covered in melted, browned Gruyère and fresh thyme.
Frequently Asked Questions
Why do the onions take so long?
Caramelising is slow by nature. Thirty-five to forty-five minutes over medium heat turns them deep brown and sweet, which is what gives the soup its flavour.
How do I know the short ribs are done?
When they are fully tender and shred easily with a fork — well beyond the 145°F minimum for whole-cut beef.
Can I broil it in any bowl?
No. Use broiler-safe crocks only, and treat them as extremely hot when they come out.
