Ingredients
  

Beef and seasoning
  • 3 lb beef chuck cut into 2-inch pieces
  • 2 tsp salt
  • 1 tsp black pepper
  • 1 tbsp butter divided
Onions and thickener
  • 4 onions large, thinly sliced
  • 2 tbsp brown sugar
  • 3 tbsp all-purpose flour
  • butter remaining portion for cooking and to brown the beef; divided
Beer-braising liquids
  • 12 oz Belgian brown ale 1 bottle
  • 1 cup beef broth
  • 2 tbsp apple cider vinegar
Herbs and aromatics
  • 4 fresh thyme sprigs
  • 2 bay leaves
Serving bread
  • 2 rustic bread slices, spread with 2 tablespoons Dijon mustard
  • 2 tbsp Dijon mustard spread on bread

Equipment

  • 1 Dutch oven

Method
 

Brown the beef and build the base
  1. Preheat the oven to 325F. Season the beef chuck with salt and black pepper.
  2. In a Dutch oven, brown the beef in batches using 2 tablespoons butter. Cook until browned on multiple sides.
  3. Add the remaining butter and the thinly sliced onions. Cook for 20 minutes, stirring occasionally, until deep golden.
  4. Stir in the brown sugar and all-purpose flour. Cook for 1 minute to coat the onions and remove the raw flour taste.
Beer-braise and bake
  1. Pour in the Belgian brown ale, beef broth, and apple cider vinegar, scraping the bottom of the pot. Bring everything to a gentle simmer.
  2. Add the fresh thyme and bay leaves. Make sure they are distributed through the liquid.
  3. Lay the mustard-spread rustic bread on top of the stew, mustard side down. Press it lightly so it sits in the braising liquid.
  4. Cover and bake for 2 1/2 hours, keeping the oven at 325F. Stir once the bread has dissolved and continue baking until the beef is very tender.
Finish and serve
  1. Remove the thyme sprigs and bay leaves. Taste and adjust seasoning with salt and black pepper if needed.
  2. Serve the beef carbonnade stew hot with fries or mashed potatoes. Spoon the dark, glossy sauce over the beef and onions.

Notes

For the deepest flavor, brown the beef in batches so the pot stays hot and you get real color before baking. Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat gently until steaming. Freezing is yes—freeze up to 3 months and thaw overnight before reheating. Dietary swap: for a gluten-free option, use a 1:1 gluten-free all-purpose flour blend to thicken (bread layer still provides body).
