My mom showed me how to make the perfect roast beef, and I mean PERFECT! I love my roast beef rare to med-rare, and this is how I do it. IMPORTANT: Take your roast out of the fridge, and let it set to get it to room temperature before baking! If you like really rare bake for 15 mins. at 500. If you like your roast beef cooked med-rare, put in for 18 mins. at 500. If you like it well done, then just burn the darn thing LOL. What's nice about this roast is, if someone likes it done a little more, please keep in mind that the end pieces will be done a little more. ***(The roast in the series of photos that I took was a 2.75 lb. bottom of the round roast. I baked it at 500 for 15 mins., then turned the oven off and left it in the oven for 1 hour for a rare roast.) The cooking time is 5 minutes per pound but I couldn't reflect that in the cooking time in the TIME section for the recipe, at the bottom so I just put in 15-30 mins, depending on size of the roast you use (3-6 lb) (Recipes courtesy of Food.com - Linda's Busy Kitchen)
