Sirloin tip roast
Food thermometer or detachable probe digital thermometer
A sirloin tip roast is a great choice for a hearty family meal. There are multiple options for what to do with this piece of meat, but the easiest thing you can do is roast it. Roasting it at 500 degrees for the first portion will ensure you get the beautiful and delicious brown caramelization on your roast. Then turning the temperature down slightly will make sure the final stage of cooking keeps all the flavors and juices in the meat. You can add any seasonings you desire to your roast or even marinate it. There is a variety of possibility's when it comes to altering the flavor of the roast, but the way you cook it will really determine how your roast will taste.
Remove the oven racks that may not allow you to use your roasting pan. You will want to roast the sirloin on the second rack from the bottom.
Preheat your oven to 500 degrees F.
Season your roast with salt, pepper, oregano, and any other seasonings. Rub the seasoning into the meat.
Drizzle olive oil over the roast and rub it in with the seasoning. This will help you brown and caramelize the meat.
Place your sirloin tip in your roasting pan and put it in the oven once it is heated. Set the timer for 20 minutes if your roast is about four pounds. If it is six pounds or more set the timer for 30 minutes. Don't open the door until the timer goes off.
When the timer goes off remove the roast from the oven. Set the oven temperature to 325 degrees F.
Insert a detachable probe thermometer into the center of the roast. Put the roast back into the oven until it reaches the desired temperature. The temperatures you want to reach are: rare meat is 120 to 125 degrees, medium is 140 to 150, and well done is 160 to 170.
Remove the meat from the oven when it reaches the desired temperature. Remove the thermometer and cover with foil to keep warm. Let the meat rest for 20 minutes before you cut it. Letting the meat rest is an essential step in the process, ensuring your roast is juicy and full of flavor.
If you don't have a detachable probe digital thermometer you can use a regular food thermometer. You will have to check on your roast every 10 to 15 minutes to ensure it doesn't overcook. Check on your roast by simply removing the roast from the oven and inserting your food thermometer into the center of the roast.
