Beef Pot Roast



  1. Preheat the oven to 275°F.

  2. Pour vegetable oil into a large oven-safe pot over medium-high heat.

  3. Season the chuck roast with salt and black pepper. Brown the meat on both sides in the hot oil, and transfer to a plate.

  4. Stir carrots, celery, and onion into the pot, and cook and stir until vegetables start to release their juices, about 3 minutes.

  5. Loosen any brown flavor bits on the bottom of the pot. Add butter, and cook until the onions are translucent, about 5 minutes.

  6. Sprinkle in rosemary, stir the vegetables, and return the roast to the pot. Cover the pot with a lid.

  7. Roast in the preheated oven until the chuck roast is tender, about 2 1/2 to 3 hours.

  8. Season vegetables with additional salt and black pepper, if desired.
