What is a Sirloin Tip Roast?
Also called a beef sirloin tip roast, or a round tip roast, this is the portion that is cut from the hindquarters of the cow and is often a tougher cut- the larger the muscle, the tougher the cut. This is not the same as a sirloin roast.
A sirloin tip oven roast should be slowly cooked to tenderize the meat, to turn this cut of beef into a masterpiece! Meat is expensive so I always use a thermometer for everything from perfect pork tenderloin to baked ham and even roast chicken!
I have both an instant read thermometer for things like steaks and chicken breasts and one I can leave in the oven for things like roasts or roast chicken. Using a thermometer ensures your dishes come out perfectly cooked and meat is juicy and tender, never dry!
How to Cook a Sirloin Tip Roast
A high temp at first creates a crust on this roast and seals in the juices (so I don’t bother to brown first). The lower temperature allows the roast to slow cook to tender perfection. This roast is lean so it is important that it isn’t overcooked (use a thermometer). It is also essential that you let the meat rest at least 15 minutes (I usually do 20 min) before carving.
- Preheat oven to 450°F.
- Allow a 4 or 5 lb roast to sit at room temperature for a good hour.
- Rub the olive oil and seasonings onto the meat and set aside.
- Slice a whole onion (yellow or white) into thick rings and place on the bottom of a dark pan. A stockpot or cast-iron skillet will do! This will be the foundation for the top sirloin roast to rest on while it roasts AND the onions provide flavor!
- After roasting, the onions can be discarded (as they tend to get quite dark) or blended with the juices and into a sauce or delicious gravy. Yum!
How Long to Cook a Sirloin Tip Roast
Slow and steady will elevate this tougher cut of meat to tasty and tender perfection! Start out at 450°F for the first 15 minutes to sear the meat and then slow roast at 300°F for 50-75 minutes. This can vary based on how cold your roast is, the shape and/or size of the roast etc.
The roast should reach an internal temperature of 135°F for medium rare. Take your roast out of the oven about 5-7° before it is cooked as it will continue to cook while resting under tented foil.
To get this right, I strongly suggest a thermometer. Remove and tent with aluminum foil and let sit for at least 20 minutes before carving.
