Ingredients

Instructions

  1. Step 1: Preheat oven to 325°F. Pat 3 lbs beef chuck roast dry and season with 1 1/2 tsp salt and 1 tsp black pepper. Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat. Sear the roast for 4 minutes per side until browned and crusty.
  2. Step 2: Remove roast and add 1 large thinly sliced yellow onion, 3 sliced sweet bell peppers, and 4 minced garlic cloves to the skillet. Sauté for 5 minutes until softened and fragrant.
  3. Step 3: Stir in 2 cups beef broth, 1 tsp dried oregano, 1 tsp dried basil, and 1 sprig fresh rosemary. Return the roast to the skillet, cover tightly with foil, and transfer to the oven. Roast for 3 hours until the beef is fork-tender.
  4. Step 4: Remove beef and keep warm. Discard rosemary sprig. To the skillet juices, sprinkle 2 tbsp all-purpose flour and whisk in 1/4 cup water over medium heat. Cook for 3-4 minutes until the gravy thickens and coats the back of a spoon.
  5. Step 5: Slice the beef thinly against the grain, spoon the sweet peppers and onion mixture over, and drizzle with the herb gravy to serve.
