Place roast beef into your crock pot.

In a bowl or measuring cup, mix together all remaining ingredients. Pour over roast beef and set the timer for your slow cooker. Cook on high for 4-5 hours or on low for 6-8 hours. I personally cooked on low for 6 hours and cooked on high for the last hour, rotating the roast beef every 15 minutes to make sure every side soaked in the gravy at the end. If you are at home while it is cooking, feel free to turn the roast beef half way through the day.

Once the roast beef is done cooking, remove carefully with tongs. The roast beef should break apart easily with two forks.

If you want a stronger taste, ladle about ¼ - ½ cup of the juice/gravy over roast beef.

Store remaining gravy in an airtight container in the refrigerator for another use.
