Carbonnade flamande is a classic Flemish stew where beef and sweet onions slowly braise in dark beer until the gravy is rich and tender.
Brown the beef in batches, soften the onions, then layer the stew with mustard-spread bread and beer so it thickens naturally as it cooks.
Choose a malty dark beer rather than a very bitter one; bitterness intensifies during the long braise.
Serving Suggestions
Serve with Belgian-style fries, boiled potatoes, or buttered noodles, plus crusty bread for the gravy and a little sharp mustard at the table.

Recipe Notes
The stew tastes even better the next day. Cool it quickly, refrigerate it, and reheat gently until bubbling at the edges.

Belgian Carbonnade Flamande (Flemish Beef and Beer Stew)
Tender beef and sweet onions braised slowly in dark Belgian beer with mustard, thyme, and bay.
Ingredients
Equipment
Method
Brown the Beef:
- Pat the beef dry and season with salt and pepper. Heat the oil in a Dutch oven over medium-high heat and brown the beef in batches, turning until all sides are deeply colored. Transfer to a plate.
- Lower the heat to medium. Add the onions and cook for 10 to 12 minutes, stirring often, until soft and golden. Add the garlic and cook for 30 seconds.
Build and Braise:
- Sprinkle the flour over the onions and stir for 1 minute. Pour in the beer and stock, scraping up the browned bits, then stir in the brown sugar, thyme, bay leaves, and mustard.
- Return the beef and any juices to the pot. Spread the bread slices with the remaining mustard and lay them mustard-side down on the surface. Bring to a gentle simmer.
- Cover and braise in a 325°F (165°C) oven for 2 hours, or until the beef is fork-tender. Remove the lid for the final 15 minutes if the gravy needs thickening.
Finish and Serve:
- Remove the thyme stems and bay leaves. Stir the softened bread into the gravy, taste, and adjust the seasoning.
- Spoon the carbonnade into bowls, scatter with parsley, and serve with fries, potatoes, noodles, or extra bread.

Notes
- A malty dark beer gives the stew depth without overwhelming bitterness; avoid strongly hopped beers.
- The mustard bread thickens the sauce and is part of the traditional texture, so let it dissolve naturally rather than removing it.
