Chop the carrots, onion, and potatoes into 1-1/2-inch cubes.

Place the beef in the slow cooker insert and add the vegetables. Break the curry sauce mix block into pieces and place into the pot. Add 3 to 3-1/2 cups of water.

Cover and cook on high for 4 hours.

Give the curry a stir at the halfway point.

When the curry is done cooking and the beef is tender, skim off as much excess fat from the top. Give it another stir.

In a shallow bowl, ladle the curry over the rice. Serve hot!
