Step 1

Allow the eye of round beef fillet to sit out at room temperature for 1 to 2 hours.

Step 2

Preheat the oven to 500 F. Place the eye of round beef in an foil-covered oven tray.

Step 3

In a small bowl, mix together the garlic powder, dried rosemary, salt, black pepper, and olive oil. Then, massage this mixture into the beef.

Step 4

Place the beef into the oven for 15 minutes, and then reduce the oven's temperature to 250 F, and allow the beef to slow roast for 1 hour, 40 minutes. Check the internal temperature with a meat thermometer until it reads at least 145 F, then remove it from the oven. Allow it to sit and rest for 15 minutes, before carving and serving.
