There’s nothing more nostalgic for me than a good Sunday roast. Beef or pork sirloin, I’m not picky, I love either one. I’ve made this sirloin pork roast for dinner numerous times and every single time it’s perfectly juicy and full of flavor. It’s probably one of the only “grown up” meals I loved as a child and I still remember sitting impatiently at the table as the aroma made me nuts.
For a dump-and-go roast option, try our Mississippi Pot Roast in the slow cooker. Tender and juicy with a gravy that’s packed with ranch and pepperoncini peppers!
Pork Sirloin Roast
And, the tradition has continued as my kids love this meal too. Pork is a succulent meat, one that many tend to overcook and dry out for fear of not cooking it long enough. This makes it inedible without mounds of gravy. Not this pork loin roast recipe, this one is the best!
I originally found this recipe on the blog, Seriously Good by Kevin Weeks. The blog is gone now and sadly Kevin passed away. While I didn’t know Kevin I did have the opportunity to enjoy this delicious recipe of his. I am sure he is sorely missed.
I’m so glad I saved this recipe. I would have been seriously bummed out to go there and find it had disappeared. Mine isn’t exactly like his, there were a few small tweaks, but it’s positively the best sirloin pork roast I’ve ever had.
This recipe is for a BONELESS roast. Bone-in roasts will cook faster!
This is my go-to sirloin pork roast recipe now. I love it, it’s perfect. So thank you, Kevin Weeks, for the great recipe!
What Type of Pork Roast to Use
Over the years there have been raving reviews for this recipe and others have had difficulty. The culprit is usually the type of pork roast used. The confusion is understandable as there are several different types and in some areas of the country, they have different names.
Therefore I am offering this photo guide to the type of pork roast this recipe calls for.
Pork Sirloin Roast, Sirloin Tip Roast, or Pork Loin Roast
- You can use either a boneless pork sirloin tip roast (arrow #1 and my choice) or boneless pork sirloin roast (arrow #2). I have also successfully used a boneless center cut pork loin (pictured at the top of the photo above), which is what boneless pork chops are cut from.
- A boneless pork sirloin roast is usually much smaller than a sirloin tip, weighing a little over a pound. Some butcher shops will tie two boneless pork sirloin roasts together to make a 3 pound roast. That’s what you see in the finished photos of the cooked roast here.
- I prefer to use a boneless pork sirloin tip roast as those are larger than a sirloin roast and I only need one.
What Roasts Not to Use
- The instructions and cook time in this recipe will NOT work for a bone-in pork roast. Bone-in roasts cook faster.
- I do not recommend using this recipe for a pork tenderloin as they are much smaller and will cook faster. Please be sure you use the correct cut of pork.
- Use the photos here as a guide just in case your butcher calls it something different. In fact, take your phone with you and pull up this post and show him/her.

How to make this Pork Sirloin Roast
- Preheat oven to 225 F.

First time making a Pork sirloin and it was scrumptious. Added celery, carrots, onion, garlic and new potatoes. Hubby liked it very much. I will add more broth next time because there was very little
“gravy” after baking. Searing the meat made all the difference and the herbs were perfect.
Deb K. says
I’ve made this multiple times as written and it’s always amazing. I was wondering if anyone has put this in a slow cooker?
I’d like to make this for Easter and I need the oven for sides at a much higher temperature.
Deb Frazer says
This recipe is a definite keeper! I have made boneless pork sirloin roasts in the past that were inconsistently tender or dry as a bone. I researched recipes and found this one and followed it almost exclusively and it was amazing. The only substitutes I made which purely was to taste was I used chicken stock instead of beef broth and I pureed the pan juices with the carrots and the onions (didn’t have any celery) which thickened it so I didn’t need any flour or cornstarch slurry to add to it. I was a little apprehensive with the cooking temperature of 225 degrees but it was absolutely perfect. Thank you for sharing this amazing recipe.
NC says
I’m wondering if anyone has tried smoking this recipe — either before searing and slow roasting or instead of slow roasting in the oven.
Janice E Smith says
Have this in oven right now…hope for the best! I didnt look back at the picture and didn’t cutup veggies real small….but they should be fine. Also got roast at Aldis and was surprised it was not tied!! It really needed to be so made due. Anybody add potatoes to roast along with? I will do them seperate .
Sure smells good!!
Nicolasa says
How can you give something five stars before you have even finished cooking it? Or tasted it?
Dana Trammell says
Bigger than the sum of its parts! That’s what this recipe is. This is the third time I’m making it and I was shocked at how good it was since it was so simple. The ingredients are inexpensive overall. I bought the boneless pork sirloin roast on a whim at Aldis because it was only $1.99 a pound & the Tyson brand. I found this recipe & it’s a keeper! Thank you for this lovely delicious recipe! It turns out more tender than I ever imagined. Do try it y’all.
Karen Dodd says
should the roast be covered while in the oven ?
Amanda Davis says
From step 5 – Place roast on top of vegetable/broth mixture and place skillet, uncovered, in center of oven.
Hope that helps!
Melissa Wamsley says
Excellent roast! Husband went back for thirds and my five year old ate EVERY bite. Trust the process. I’ve never cooked at 225 before and it made me a little uneasy. But then I remembered I searched for a recipe because I’m not a chef. Followed it exactly as written. My sirloin roast was just over two pounds and it took right around the 1:20 mark to be cooked to 145. Everything about the recipe was spot on. The best part was the veggies and pan drippings on top of the sliced meat. We are looking for ways to cut our grocery bill and this cut of meat is perfect. This is going into our regular rotation for sure! Thank you for sharing this.
Nancy says
I don’t think a 3 lb roast would serve 16?
Amanda Davis says
Thanks for pointing that out, it should be 6. Corrected
April says
Simply amazing…..defiantly the best pork roast I have ever tasted and so easy!
Vickie Ramsey says
This is ABSOLUTELY the BEST RECIPE EVER FOR a pork roast. I followed your instructions to the letter. It is so delicious that I almost licked my plate. The flavors are fantastic. The only thing I would do next time is make more of the veges for the gravy. What an amazing topping for the sliced roast.
Rosemary says
I made this recipe just as written with a small boneless cheap pork roast and it was sooooo good.. Definately a keeper recipe. My roast was a little smaller, and I cooked it in a convection oven, and it was done in an hour. Excellent!
Becky says
Excellent recipe. I strained out the veggies and made the drippings into gravy to be served over mashed potatoes.
Don says
225 degrees? Take a lot longer than 2 hours. I believe you meant 325 degrees.
Amanda Davis says
225 is the correct temperature.
Becky says
Mine cooked in about 2 hours at 225. Note that it is a (small) 3lb roast called for in the recipe.
Lori Leslie says
Made this roast according to recipe. It was so flavorful and moist! This is definitely a keeper.
Roxana says
Made this last night. My family loved it.
Such an easy recipe but great flavor.
Jenny says
The meat was beautifully tender but my piece had quite a top layer of fat and skin to make crackling so I changed the first part of the recipe and put it in the oven for 30 mins on 220’C to help with crackling. It didn’t quite make it at the end so I’ll grill it separately to achieve the result I’m looking for. The main thing is that the port itself was very tender and tasty! The recipe is in my scrapbook!
Karen Ashline says
Made this last night it was awesome, cooked perfect for the temp wonderful flavor.
Suzanne T. says
Hi Amanda! I just had to leave a comment because I actually used your recipe with a close to 5 lb bone-in pork sirloin roast, and it came out AMAZING!! I was nervous because of all the warnings to not use a bone-in roast, but I simply could not find another recipe that had the elements I was looking for. Luckily, you posted the warnings about a bone-in roast cooking faster, so I made sure to use one of those meat thermometers that you leave in while the meat is cooking and then sounds an alarm when the target temperature has been reached. Well, let me just say that this recipe works 100% with a bone-in roast. The meat was juicy, flavorful, and even my son who doesn’t like pork all that much gave it high praise! The total cooking time turned out to be similar – just about 2 hours – probably because of the bigger size of the roast. This will now be my go-to recipe for that cut!
Amanda Formaro says
Awesome, so glad to hear it, thank you!
Donna Shelley says
Cooking yesterday for my husband and I while we had Covid I was happy to see an exact match of all the ingredients. I had a sirloin roast that was identical to this recipe, all tied together with that elastic string that I actually dislike. The roast came in a plastic bag with much blood juices. I probably should have drained them off, but didn’t and the grey matter that became thicker as it browned was disgusting. I ended up trying to pick out the grey masses and tossing. I don’t have an iron pan so I did my best with another type heavy pan. I had the oven to temp 225 as requested and waiting the two hours altho I did check intermittently with therm. At the two hour point everything was almost as I put it in the oven…not particularly cooked. 225 is a warming oven…not a cooking oven…but I stuck it out and put it back in for yet another half hour. Being sick we were sensitive to being hungry after smelling this in the oven…it was yummy smelling. After the 2 2/5 hour point I checked again. The therm only approached the 140 mark. Back in again for another half hour. So now I was hungry. So at the 3 hour point I checked again and it barely touched the 140 temp. I was going mad. I put it back again ending up only getting it close to 145 after four hours! and raising the oven to 300. I was so frustrated that I let it sit on the stove while we ate instead some chicken cacciatore my neighbor kindly brought over knowing that we were sick. I’ll take it out today and warm it up and see if it’s really done. I don’t trust any pork cooked at a warming oven temp. So disappointed.
Scott Jayson says
Hi Donna.
Sorry things didn’t work out as planned for you. I would respectfully suggest that you get an oven thermometer. Many home ovens are off by as much as 50 degrees from the selected temperature, and if that was true in your case, you might have been roasting at 175 degrees! 225 degrees is a legitimate roasting temperature in certain circumstances – many people roast their turkey at a low temp for instance, and it certainly worked well for me in this recipe. I hope you try it again and get a great result.
