Sirloin Tip Roast Pulled Pork

Sirloin Tip Roast Pulled Pork is one of my favorite things to make on my pellet grills. Sirloin Tip Roasts aren’t traditionally used for pulled pork, but don’t let that stop you. This was some of the most tender, moist, and flavorful pulled pork I’ve ever had. Plus, it is super economical. We pick these up at Costco and they are so versatile (and cheap!)

Costco Pork Sirloin Tip Roasts are PERFECT for pulled pork. Smoked on the pellet grill for 4-5 hours at 180 degrees, and then tossed into the slow cooker for another 12 hours. You can save your pellets and still have some of the most fabulous pulled pork you’ve ever tasted. You can also use your Instant Pot if you need to shave some time off of this, and high-pressure cook for 1-2 hours and then slow cook until fork-tender and shreddable. 

Pork seems to be one of the most economical meats to buy lately, and you can make such a large variety of dishes with it, you really can’t go wrong.

I served my pulled pork on a sesame bun with BBQ sauce and coleslaw, DEEEE-licious!

You can use whatever kind of rolls you like for these sandwiches, and for that matter, whatever kind of sauce and toppings you prefer. If you would like your guests to assemble their own sandwiches, serve all the condiments and toppings on the side and they can build their own masterpiece.

This pork is just as delicious without the bun so anything goes.

Pulled pork tacos are also legit, and if you crisp them up in a fry pan first you could even get away with calling them smoked carnitas.

What cut of pork works best for pulled pork?

The pork shoulder is the most widely used cut for pulled pork. But you can use basically any roast that is high in fat and connective tissue. The key is in the method you use to cook the meat. Low and slow is the way to go.

The Sirloin Tip Roasts that I used in this recipe are a cut that has less fat than the shoulder roasts, smoking them first and then finishing in the crock pot for a long period of time still produced a wonderful, tender and moist pulled pork. So as I mentioned earlier, the key is in the method of cooking.

How long does pulled pork last in the fridge?

You can store your leftovers in ziplock freezer bags, foil, or plastic containers for up to 3-4 days. After that you will want to freeze the remainder.

A vacuum sealer is really ideal if you want to make things last for more than a couple of months in the freezer. If you don’t have one, try and use your frozen pulled pork in about 4-6 weeks for the best results.

What’s the best way to reheat pulled pork?

If you are just reheating yesterday’s dinner, the microwave will do the trick quite nicely. Just slather with your favorite sauce and the pop into the mic for a minute or two, until it is hot. 

If you are going from the freezer to the table, the best method to reheat your frozen pulled pork is to thaw it first in the fridge overnight, and then reheat it in the sealed plastic baggies in a bath of hot water. This is the sous vide method, and will get you the best results. 

If you don’t have a sous vide or if you are going from the freezer to the table without thawing overnight first, a crock pot works really well on high. I’d just add in some bbq sauce to the mix while you are heating, and stir it every hour or so until it is thawed and heated thoroughly.

Yield: 12 servings

Pork Sirloin Roast Smoked Pulled Pork

Costco Sirloin Roast Smoked Pulled Pork

This delicious pulled pork is made with a surprising cut of pork: a sirloin roast! These economical roasts are widely available as 4-packs at Costco, and are one of my favorite things to use for this recipe.

Prep Time 20 minutes
Cook Time 7 hours
Total Time 7 hours 20 minutes


  • 2 pounds of pork sirloin roast
  • 1/2 cup pork rub
  • 2 tablespoons kosher salt
  • 2 cups apple juice or hard apple cider
  • 2 cups barbecue sauce


  1. Turn your pellet grill onto smoke mode, or set it to about 180-190 degrees or as close as you can get to that. You want to really hit this hard with smoke.
  2. Coat your pork roast with the Everything Rub and salt, and place it on the grill.
  3. Smoke for 3-4 hours, flipping several times during the smoking time.
  4. Next, you have some choices to make. If you have a slow cooker, I suggest tossing your roasts into that at this point, on low or medium, adding the apple juice or hard cider, covering, and letting it ride for about 8-10 hours (up to 12, even, if you wanted to) until the roasts are fork tender and shreddable.
  5. OR, you can get hardcore and just keep it going on the smoker. If you want to go that route, continue on. If you are taking the slow cooker route, you can stop reading now.
  6. Turn the grill up to 325°, and place the sirloin roasts into a grill-safe pan. Pour in two cups of apple juice or hard apple cider. Cover tightly with foil and cook for another 2 hours.
  7. Remove the cover from the roast and check the temp at this point. These will shred at about 205°. Flip the roasts over in the pan, and leave the foil off the roast and cook uncovered until it is shreddable.
  8. Shred and mix with your favorite bbq sauce and serve!

These directions are confusing, so insta-pot and then slow cooker or insta~pot and then smoker or smoker than insta-pot?

Are you looking in the recipe card? #1-3 explain that the roast should be smoked first. Then, you get to decide how to proceed. You can use either an Instant Pot on slow cooker mode or in a regular Slow Cooker. OR, if you don't want to use a slow cooker or instant pot you can just finish the whole thing on the grill. Steps #5-7 cover that part. Let me know if you have any other questions!

Do you mix the two tablespoons salt, 2 cups hard cider, and 2 cups bbq sauce together? And then that all goes in the slow cooker with the smoked pork?

@Nicole Johnson, thank you! I smoked this last night, and put it in the crockpot overnight, to have for lunch today. My husband usually won’t eat pork roast, but he ate this, and liked it!!!

Do you know how long to cook if using an instant pot instead of slow cooker?

Nicole Johnson

Friday 3rd of September 2021

Hi Katy! You can use your Instant Pot if you need to shave some time off of the cook. I high-pressure cook for 1-2 hours and then slow cook until fork-tender and shreddable. Start with one hour, do a NPR, and then check it. If it is still not even close, do it for another hour.

So one minute we are talking about 4 hours in the smoker and then 12 hours in the crock pot, then we move on to a complete other method?????, so what goes in the crock pot with the roast for 12 hours?????

Whoooops. Nice catch, William! Sometimes being your own editor is awesome, and other times you miss things like this. ;)

This recipe is actually fine either way - whether you choose to do the tail end of the cook in the crockpot or on the grill. Either way, after the initial smoke, your roasts go into a grill-safe pan or the crockpot with the apple cider or hard cider and get covered and cook until they are fork-tender and shreddable. I updated the recipe to reflect this as well. Thanks again for visiting!
