Perfect Top Sirloin and Sirloin Tip Roast

Sirloin is an infamously tricky piece of meat to cook properly. It has an unfortunate tendency to rcook id not done right and taste like tough, chewy shoe leather.

The trick, however, is to get the temperature right. You want to carefully control the temperature the meat cooks at, both to help control browning and to ensure it doesn’t overcook.

Some deliciously insulating and flavorful seasoned butter and a handy instant-read thermometer should be all you need to make a delicious and hopefully entirely edible top sirloin roast.

  • Combine the butter and seasoning together
  • Cover the top of the roast with the butter mixture
  • Place the vegetables in the bottom of the roasting tray, and roast at 450 Fahrenheit
  • Turn the temperature down to 325 Fahrenheit, and then cook until your sirloin roast hits 10 degrees before you reach your desired temperature

What Seasonings To Use For This Recipe?

The seasoned butter is really the key in this recipe. It not only flavors the meat with some tasty butter, but it also helps keep the meat moist and enjoyable.

You need to pick a really good seasoning blend to help flavor it; however, other the meat will end up tasting like nothing but butter.

Despite how good that might sound, some kind of flavorful spice mix is necessary; any of the pre-made mixes at the supermarket work great here, such as garlic and herb or even just plain Italian seasoning.

Feel free to play around with your own preferred blend of seasonings as well – mix some dried garlic and a few different dried herbs, or just take any kind of seasoning that you like and mix it all together!

Tips and Tricks for CookingTop Sirloin and Sirloin Tip Roast

Almost any sirloin roast is basically guaranteed to end up overcooked and tough unless you use some really good temperature control.

First of all, the amount of time your sirloin roast will spend in the oven is going to entirely depend on its weight. You want to cook for about 20 minutes per pound of the meat, but that is also going to depend on the quality of your oven and how well it evenly distributes its heat.

The idea behind setting the oven really hot and then reducing it to 325 is that it lets the outside brown really nicely without burning, and then the remaining lower temperature can help the meat to more gently come up to the proper internal temperature.

The final temperature you want for your roast is going to entirely depend on what kind of meat you want.

For a nice rare top sirloin roast, aim for the final temperature to be around 120 Fahrenheit. For a more tender medium-rare, shoot for about 130 Fahrenheit.

Of course, you want to be pulling it from the oven and resting it a full 10 degrees before your target temperature. Don’t worry about accidentally undercooking the meat when you pull it out early; the carryover heat will continue to cook the roast as it sits, resulting in perfectly cooked beef every time.

Temperature Guidelines for Roasting Sirloin

Prime Rib Roasting Internal Temperatures

Blue in the middle– 110 degrees – when the middle of the roast still “quivers”

Rare- 120-125 degrees in the middle

Medium-rare– 125- 135 degrees in the middle

Medium – 135- 140 degrees in the middle. You usually don’t want it cooked this much as you lose the tenderness that prime rib is known for.

Medium Well-140- 150

Well-done– 155 +

  • 4-6 pounds sirloin roast top sirloin or sirloin tip


  • 1/2 cup butter softened
  • 2 teaspoons dried rosemary
  • 2 teaspoons minced garlic
  • 1 teaspoon flaked sea salt
  • 1/2 teaspoon dried thyme
  • 1.4 teaspoon ground pepper


  • 6-8 cups of carrots/potatoes/onions cut into large chunks you can make more in a large roaster if you are feeding more people


  • Remove your roast from all its packaging and let it sit out for an hour until it’s about room temperature.
  • Pre-heat your oven to 450.
  • Mix the butter and seasoning together until combined.
  • Cover the top of the roast in the butter mixture.
  • Place the vegetables in the bottom of the roaster.
  • Place the roast in the center of the vegetables.
  • Place in the oven – without the lid! – and cook for 15-20 minutes, until the top of the roast is seared and brown.
  • Turn the oven temperature down to 325 and place the lid on the roaster.
  • Cook to 10 degrees BEFORE your desired temperature – 120-140 – see my chart in the post. Your roast will continue cooking after you pull it out of the oven.
  • Remove and set on stove for 20 minutes, keeping the lid on and the roaster sealed ( instead of tenting with tinfoil.)

  2. Mushroom Matt says

    This site and the recipes are unusable due to the insane amounts of popups, overlays, and inline ads. It’s absurd. I spent 5 minutes trying to read the recipe on a mobile device and couldn’t get a glimpse. Even as I write this review 2 different popups came over where I was trying to type. This is absurd.1 star

      What browser are you using? There is one small video pop-up on my phone but isn’t in my way.
