Perfect Sirloin Tip Roast

Step 1

Preheat oven to 450°F.

Step 2

Remove roast from the refrigerator at least 45-60 minutes before cooking.

Step 3

Rub roast with olive oil and seasonings. Slice onions into thick rings (do not separate rings) and place in the bottom of a dark pan.

Step 4

Place roast on top of onions. (You may not need all of them, you need the onions covered by the roast or they will burn).

Step 5

Roast at 450°F for 15 minutes. Reduce heat to 300°F and roast until cooked to desired temperature. (135°F for medium-rare, 145°F for medium), about 90 minutes more.

Step 6

Remove from oven (a few degrees before it's done, I usually take mine out at about 142°F and loosely tent with foil. Let rest at least 20 minutes before slicing.

Step 7

Discard onions and save any drippings for gravy or freeze to add to soups or stews.
