Insert an ovenproof meat thermometer into the thickest part of the roast beef, cover, and set the slow cooker to the low setting. Roast beef is baked to a perfect medium when the internal temperature reaches 131 °F, approximately in 2 to 4 hours, depending on the weight and thickness. Check the roast beef after 2 hours and every 20 minutes after that until the desired temperature is reached.
At 131 °F, remove the whole roast beef from the slow cooker and cover with aluminum foil for at least 10 minutes. Meanwhile, make the sauce.

2 teaspoons cornstarch
Remove the toothpicks and thinly slice the roast beef to serve. Drizzle with the honey-garlic sauce.
