1. Preheat the oven to 500 degrees Fahrenheit.
Pat the bottom round roast dry with paper towels to allow the butter mixture to stick.
2. Place the roast in an oven safe skillet. Combine butter, rosemary and minced garlic. Spread the mixture by hand over the roast covering as much as you can.
3. Place the roast in the oven, close the oven door and reduce the temperature to 475 degrees Fahrenheit.
4. Roast for 7 minutes per pound and then turn the oven off completely (keeping the oven door closed).
After 1 hour, turn the oven on to 200 degrees Fahrenheit and cook for approximately 1 hour or until the internal temperature of your roast reaches your desired temperature (rare, medium, etc).
