Top Sirloin Roast Recipe

Cooking a sirloin roast is probably one of my least favorite things to do. Let’s face it, sirloin roasts are not the best roasts. They don’t fall apart into delicious pieces after a long, slow cook like chuck and blade roasts do. They also are the least inherently tender cut of roast, so it won’t be delightfully tender like a prime rib roast.

So I don’t buy sirloin roasts.

However,  my husband accidentally does. Two roasts, in fact, after a trip to the grocery store. I took one look at them and sighed. I am super lucky that Mike happily (ok, happily might be pushing it) does the grocery shopping, so who am I to complain when he shares the workload?

So here I was, stuck with the cut of roast that I like the least. However if there is one thing that I have learned, when life gives you roasts, eat them. I figured that I would cook it exactly like my method in my popular post How to Cook A Prime Rib Roast. That post is one of my most popular ones come the holiday season, and for good reason. There is nothing worse than wrecking a roast for dinner!

Sirloin roasts are also more affordable. Who can afford to have prime rib for dinner every week? Not this kid. So learning to cook a sirloin roast the best possible way is also in my bank accounts best interests. Like my Dad said, I am the classic “Champagne taste on a beer budget” kinda girl.

OR even better, a “Prime Rib taste on a sirloin tip budget” kinda gal. Take your pick, they both apply to me!

So learning how to cook a sirloin roast is a life skill, my darlings.

The real key is getting the temperature right on the roast. You need to pick the doneness you want – and remember to let it rest for 20 minutes. This is the most important part. Pull it out 10 degrees before your desired doneness and let this roast sit in the roaster, cooking some more but also allowing the juices to disperse evenly throughout the roast before you carve it.

Cooking Temps are as follows:

Blue in the middle– 110 degrees – when the middle of the roast still “quivers” I can eat blue steak like nobody’s business. Pretty sure it’s my low iron.

Rare- 120-125  degrees in the middle. Red, bloody and delicious! The roast is warm all the way through.

Medium-rare– 130-135 degrees in the middle. The center is pink, with slight brown towards the outside. See the photos of the roast in this post.

Medium – 140 degrees in the middle. Barely pink with brown to the outside.

Well-Done – 160 degrees and over. Brown throughout. Resembles shoe leather. ( I kid, I kid. You’d be surprised how many people get crotchety when I tell them not to ruin a roast by cooking it well done. Each to their own. babes!)

Top Sirloin Roasting Time per Pound

A top sirloin roast done in this low and slow method will take you approximately 20-22 minutes per pound of meat, but of course that will depend on your oven and how it cooks. So a 6 lb roast will take around 120 minutes ( 2 hours) to cook. This also depends on the thickness of your roast, if you let it come to room temperature and a lot of other factors. Use a good thermometer and start checking after the hour point of cooking.

This was an excellent sirloin roast that the entire family loved, so I am confident that that second roast that Mr Magpie bought at the store is headed to the oven fairly soon, and in the exact same manner. Let’s face it,  learning how to cook a sirloin roast properly will still never yield you a prime rib quality, but at least it’s going to be as delicious as you can get for that cut of roast!

Happy Cooking guys!

Love you more than chocolate,

Karlynn

Ingredients

  • 4-6 lb sirloin roast
  • 1/2 cup butter. softened
  • 1-2 tbsp your favorite seasoning
  • 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

Instructions

  1. Remove your roast from all its packaging and let it sit out for an hour until it’s about room temperature.
  2. Pre-heat your oven to 450.
  3. Combine the butter and seasoning together ( you can use a herb and garlic mix, Italian seasoning, anything that you can think of!) .
  4. Cover the top of the roast in the butter mixture.
  5. Place the vegetables in the bottom of the roaster.
  6. Place the roast in the center of the vegetables.
  7. Place in the oven - without the lid! - and cook for 15-20 minutes, until the top of the roast is seared and brown.
  8. Turn the oven temperature down to 325 and place the lid on the roaster.
  9. 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.
  10. Remove and set on stove for 20 minutes, keeping the lid on and the roaster sealed ( instead of tenting with tinfoil.)

    I used to have an uncle that raised cattle. He used to get the best cuts of beef. His wife then cooked them until they were grey, tough and tasteless.
    I married a French woman. In France they much prefer rare beef. (In a restaurant in France you can order beef however you like, but it will probably be served rare.) I now cook my beef rare, using a thermometer; it’s definitely the way to cook beef!

  2. kelly says

    thank you so much your are the bomb, everything worked out perfecto.

  3. Haylie says

    Hey there! I’m wanting to make this tonight for my family! I don’t have a meat thermometer so I was wondering for about how long did you actually cook it when you turned the heat down? I have about a 3lb roast and like it on the medium/medium rare side. Any feedback is greatly appreciated

  4. Terri says

    I will be making your recipe tonight, sound delicious! Very easy to follow your instructions. Your reviewer, STFU really needs to learn to follow instructions. Obviously she was having a bad day at least I hope that is her problem.

    • Karlynn Johnston says

      Aw thank you for your kind words! I did delete the comment because of the foul language in it, nobody needs to see that on a family-friendly website. I hope you love the roast!!!5 stars

  5. Denise Groleau says

    I tried it. Very pleased!! Thank you very much. I added some sauteed mushrooms.5 stars

  6. Andrew says

    Trying this tonight as we are all on self isolation and this Sirloin Tip roast is in the freezer and its Easter Weekend…so wish me luck…thanks fo posting Karlynn
    ps- the recipe is not misleading at all 🙂

  7. Mrs. R says

    Made this tonight with a 2.5 pound sirloin tip quick roast from Walmart. Turned out fantastic, followed directions for browning at high heat for 15 mins then turned it down and cooked it for 55 mins. Took it out when the thermometer read 135 degrees and rested for 20 mins. Carved it up and it was awesome. I have never had luck putting sirloin roasts in the crock pot, and since this method worked so well it will be a go to when cheap sirloin tip roasts are available on sale. Thank you for sharing this recipe.5 stars

  8. Kathryn Bracht says

    I’m confused now. Was this roast sirloin tip or top sirloin? I need a recipe for roasting sirloin tip ….

    • Karlynn Johnston says

      You can use this for tip sirloin as well! It’s great for cheaper cuts of beef.5 stars

  9. Grace Chadwick says

    Laughed so hard! That could have been me that wrote that, right down to 2 roasts! Cooking mine now and confident it will be awesome ?

  10. Mar says

    GREAT recipe!…. (For the butter rub, I had S&P, garlic and onion powder, parsley flakes, and 1/2 tsp Tarragon.)… The gravy I made with the drippings from the pan, was SUPERB! I placed yellow onions and carrots under the roast, and followed the recipe for cooking times. PERFECT Results!…. this roast is a more economical choice, the results are 5 star kitchen chef!!!!…. thanks for sharing!5 stars

  11. Tyler says

    Very good recipe! Second time doing it with a smaller toast and it turned out great again. Thanks for the recipe!5 stars

  12. Kevin says

    Hi Karlynn. As a Costco meat manager I thought I would chip in with some clarification for your website fans. Your recipe is titled “top sirloin” roast but I believe in your description of the cut, you are referring to “sirloin tip”. There is a big difference between the two: the sirloin tip is actually a round roast from the beef hip and I agree, it can be somewhat tough depending on the grade and will dry out if cooked to well done. The top sirloin, however, is from the loin or lower back and is considered steak quality. It will have more fat marbling and should be more tender, juicy and flavorful because of that. After the rib roast, top sirloin is perhaps my favourite cut to dry roast. Hopefully this will be helpful to your followers. Keep the great recipes coming!

    • Mary says

      This is so helpful since this entire post is rather misleading based on your input. Can you please provide accurate information about the best way to prepare a top sirloin filet roast?

      • Karlynn says

        Also sirloin TIP is a flatter, boxier round-ish roast if you look at photos. Totally different than this one. They can both be cooked this way though.5 stars

  13. Sandi says

    I’m with you Karlynn, not a fan of sirloin tip, however it turned out good. Unfortunately I lost track of time and left it in the oven a bit to long. Ideally prefer med. rare, but everyone ate and no one complained.5 stars

  14. Donna M. says

    Fantastic recipe! I followed the recipe but just used butter & salt & it turned out amazing. We like out meat well done & it turned out well & was tender!!!! I had no leftovers, everyone loved it. Thank you for sharing this excellent recipe. Totally will try other recipes & follow you on Pinterest!5 stars

    • Karlynn says

      The package, which came from Costco because that’s the only place I buy meat, said top sirloin. Just because the commenter feels that my “description” doesn’t fit what he thinks the roast is doesn’t mean that it’s not.

      Note that he didn’t say it doesn’t look like a top sirloin roast. He just doesn’t agree with my description that it’s a leaner cut but if you Google it it says that it can be a juicy leaner cut.

      it’s not misleading at all I have a lot of roast beef recipes and I am working my way through every single type of roast and being thorough so that everyone knows how to cook each kind.5 stars

  15. Dave says

    Nicest sirloin roast I’ve ever had. I was a little skeptical, because I was putting the seasoned butter on top of a healthy fat pad, but I can’t argue with the results. This was a roast that I moved frozen from my last house, stale-dated almost 3 years. It turned out very nearly as tender as prime rib. Will remember your recipe.5 stars

  16. Cheryl Tait says

    Such a great recipe!!! I cooked this for my family for Christmas Eve dinner, and it was delicious!!! I used two large cloves of minced garlic, parsley and 1/2 pound butter, salt and pepper on a bed of onions. Seared it at 450 for 30 minutes and then 285 for 3 hours. Sounds extreme, but because we like the meat well done, it came out EXCELLENT!!5 stars

  17. Diane says

    This turned out delicious! I did leave it in the oven a tad too long, but it turned on pink in the middle. So good!5 stars
