Ingredients

Instructions

  1. Step 1: In a large Dutch oven, heat 2 tbsp olive oil and 2 tbsp unsalted butter over medium-high heat until shimmering. Season 2 lbs beef chuck cubes with 1 tsp black pepper and 1 tsp salt, then brown the beef in batches for 4-5 minutes per batch until deeply browned on all sides. Remove beef and set aside.
  2. Step 2: Add the remaining 2 tbsp unsalted butter to the pot. Reduce heat to medium, add 4 large thinly sliced yellow onions, and cook, stirring occasionally, for 20 minutes until deeply caramelized and golden brown.
  3. Step 3: Stir in 3 minced garlic cloves and cook for 1 minute until fragrant. Sprinkle 2 tbsp all-purpose flour over the onions and stir continuously for 2 minutes to cook the flour.
  4. Step 4: Gradually pour in 4 cups beef broth and 1 cup dry Belgian-style beer, scraping up any browned bits from the bottom of the pot.
  5. Step 5: Return the browned beef to the pot along with 3 fresh thyme sprigs, 2 bay leaves, and 1 tbsp brown sugar. Stir well and bring to a simmer.
  6. Step 6: Cover the pot partially and reduce heat to low. Let the stew simmer gently for 2.5 to 3 hours until the beef is fork-tender and the sauce has thickened.
  7. Step 7: Remove thyme sprigs and bay leaves. Adjust seasoning with extra salt and pepper if needed. Serve hot with crusty bread or boiled potatoes.
