  2. Season the boneless beef chuck roast with 3 tablespoons of the salt. Rub the salt into the grain and cover all sides. Wrap the roast tightly in plastic and chill at least 3 hours and up to 3 days.

  3. Heat 2 tablespoons of the vegetable oil in the slow cooker on the sauté setting. Cook the roast, until golden brown on all sides. This will take about 10 to 12 minutes. Remove the roast from the slow cooker and set aside.

  6. Add the beer, marjoram, thyme, and bay leaf. Cook, stirring occasionally and scraping bottom of pan, until slightly reduced and you can no longer smell the alcohol, about 2 minutes.

  9. Arrange the carrots, potatoes, and mushrooms around roast. It will appear as if there isn’t enough liquid, but the juices from the roast and vegetables will release as they cook.
