Best Pork Shoulder Roast

I was talking with my friend Chris about perfect meals for entertaining, and we went though the usual suspects: lasagnas, chili, tenderloins, and then he mentioned to me that his favorite  go-to entertaining dish was a pork butt or shoulder.  We talked about the best way to cook a pork shoulder roast: basically just letting it slow cook in the oven for ages at a very low temperature so  that it practically falls apart.

How to Cook Pork Shoulder Roast

Chris told me that long ago a chef has explained to him that meat likes to be cooked at around the temperature that it reached when it is done.

While I don’t think that is always the case at all (flame kissed steaks and burgers anyone?), it made nice sense when I thought about it in terms of a big tough hunk of meat, like this boneless pork shoulder roast, which needs low and slow cooking to make it turn from impossibly tough to tender.  No amount of trying to rush the process will help, you’ve got to keep the heat low and the time long. 

Pork Butt Roast

You can also make this recipe and others like it with a pork butt roast or Boston Butt pork roast, which are actually also from the shoulder area, a little further up, but essentially a similar cut of meat.

Slow Cooking Pork in Oven

When you slow cook pork shoulder in the oven, boneless or bone-in, you have a lot of flexibility, which is a delightful thing when entertaining.  In fact, the cooking time at this low temp could be stretched by an hour or two, and the roast wouldn’t be any worse for the wear.  So you can literally plunk it on the table whenever everyone is ready to eat. 

Fat Side Down or Up?

And even though this recipe calls for boneless pork shoulder, which is a bit easier to cut, you can use bone-in pork shoulder which will cook in about the same amount of time. The instructions call for the fat side to be down in the pan, which give the top the chance to get a nice crust, but it really doesn’t matter. Some people like the fat on the top, which kind of bastes the pork as it cooks, but then you have less crusty surface. Your call, you won’t go wrong.

The best part?   This is free time you can spend reading, dancing, sleeping, cleaning a closet, saving kittens from trees.

Low and Slow and Flexible

The flexibility of this recipe bears repeating, because it’s one of the best things about this dish. You can leave the roast in the very low oven for another hour or two or even three with no repercussions.  The pork is roasted uncovered so that it gets a wonderful crusty brown exterior, while the inside becomes fall-apart tender.

If you feel like it needs a bit more browning or caramelization at the end, turn the heat up to 450°F. for 15 minutes before pulling it out of the oven. Make sure to let it rest for a bit so that the fibers can relax a bit, and the juices re-group.

And do know that if all has gone as planned, the meat will be so tender that the slices won’t hold together.  That’s part of the appeal.

For a Smaller Pork Shoulder Roast

If your roast is smaller than 6 pounds, you can still use the recipe fully successfully, just shorten the cooking time slightly. You still want to start it at high heat, in a preheated 450°F oven. Roast the pork for 20 minutes, then turn the heat down to 250°F and continue to cook for 4 to 7 hours until the middle of the roast registers 180°F on an internal thermometer, and as you slide the thermometer in you can feel that the meat is very tender throughout.

  • For a 3 pound pork roast, start with the heat at 450° for 20 minutes, then turn the heat down to 250°F and continue to cook for 4 to 5 hours until the middle of the roast registers 180°F.
  • 4 pound pork roast: Start with the heat at 450° for 20 minutes, then turn the heat down to 250°F and continue to cook for 4 1/2 to 5 1/2 hours until the middle of the roast registers 180°F.
  • 5 pound pork roast: Start with the heat at 450° for 20 minutes, then turn the heat down to 250°F and continue to cook for 5 1/2 to 7 hours until the middle of the roast registers 180°F.

For a Larger Pork Shoulder Roast

A larger pork roast still starts with a short burst of high heat roasting, then is cooked low and slow for a longer amount of time. Again, you want the meat to be falling apart tender. Every piece or pork and every oven is different, so use the below time ranges as a guideline, start checking at the shorter end of the cooking time, and if you need to let it go longer to get tender, that’s fine. Once it begins to get tender check every 30 minutes until it is fully tender and falling apart.

For anything larger than a 6 pound roast, you will want to add another half of the marinade ingredients to the blend. If you have a 10 pound or larger roast, you’ll want to double the marinade.

  • 7 pound pork roast: Start with the heat at 450° for 20 minutes, then turn the heat down to 250°F and continue to cook for 7 to 8 1/2 hours until the middle of the roast registers 180°F.
  • 8 pound pork roast: Start with the heat at 450° for 20 minutes, then turn the heat down to 250°F and continue to cook for 7 1/2 to 8 1/2 hours until the middle of the roast registers 180°F.
  • 9 pound pork roast: Start with the heat at 450° for 20 minutes, then turn the heat down to 250°F and continue to cook for 8 to 10 hours until the middle of the roast registers 180°F.
  • 10 pound pork roast: Start with the heat at 450° for 20 minutes, then turn the heat down to 250°F and continue to cook for 8 1/2 to 10 1/2 hours until the middle of the roast registers 180°F.

Substitutions for Anchovies

I fully recommend the use of anchovies in the marinade, which don’t add any kind of strong fishy flavor, but rather a depth of overall flavor which I promise won’t taste like anchovies. If you don’t have them, or don’t want to use them, you can sub in 2 teaspoons fish sauce, 3 teaspoons minced capers, or even 2 teaspoons soy sauce.

Ingredients 

  • 2 tablespoons chopped garlic
  • 3 anchovies, rinsed
  • 2 tablespoons chopped fresh rosemary
  • 2 teaspoons kosher salt
  • 1 teaspoon freshly ground pepper
  • ¼ cup olive oil
  • 2 tablespoons coarse Dijon mustard
  • 1 6-pound boneless pork shoulder trimmed of excess fat and tied

Instructions 

  • In a small food processor combine the garlic, anchovies, rosemary, salt and pepper. Add the olive oil and process until it forms a paste, scraping down the sides. Remove the blade and use a fork or spoon to stir in the mustard. Rub the paste all over the pork shoulder, loosely cover it with plastic wrap, and refrigerate from 2 to 24 hours.
  • Preheat the oven to 450°F and bring the pork to room temperature while the oven heats. Place the pork in a shallow roasting pan and roast, uncovered, for 30 minutes, until the top starts to brown a bit. Turn the heat down to 250°F and continue to cook, uncovered, for 6 to 8 hours until the middle of the roast registers 180°F. on an internal thermometer, and as you slide the thermometer in you can feel that the meat is very tender throughout. If there are juices in the pan (and I have found that sometimes there are and sometimes none) pour off the juices from the pan into a heatproof container, like a Pyrex measuring cup. Place this in the fridge, where the fat will rise to the top, while the meat rests.
  • When the meat is cooked, if you think that the outside of the roast could use a bit more crust/brownness, turn the heat back up to 450°F and let it cook for another 15 to 20 minutes, to give the outside a bit more of a crunchy texture.
  • Remove from the oven and let sit for about 20 minutes. Spoon the fat off the reserved juices in the fridge and pour the cooking juices into a serving pitcher or bowl (warm it a bit in the microwave or in a small pot if you like). Slice the pork as thinly or thickly as you like, knowing the meat will fall apart at least slightly. Sprinkle the sliced meat with a bit of salt before serving, and pass the pan juices on the side to drizzle over.

    Hi – do I leave the skin or crackling on the pork or cut it off?

    1. Katie Workman says:

      leave it on! it’s delicious with the softer interior meat!

  2. Angie Brown says:

    Can I cook it the same way in an electric roaster? That would open my oven up to roast some veggies.

    1. Katie Workman says:

      I’ve never done it, but I think if it’s large enough it will work!

  3. Patty McKechnie says:

    Excellent, your explanation of recipe was great for me as I have never cooked a pork shoulder roast before. I used fresh rosemary, fresh garlic; course ground mustard; and instead of anchovies, I used some whoreshire sauce. I served it with coleslaw and sliced tomatoes, and corn bread. Yum….thankyou Katie.

  4. Mel says:

    Which rack level in the oven do you place it in? Middle, lower?

    1. Katie Workman says:

      middle or lower is fine!

  5. Erin says:

    The recipe calls for 30 min at 450 up front, but when walking through the various weights of pork you note 20 minutes. Is there a preference?

    Thanks!

    1. Katie Workman says:

      It’s kind of flexible – I would go for 20 with a smaller roast, and 30 for a larger!

  6. Julie says:

    I have a 2.6 lb roast marinating in the fridge. I put it in at 7:00 last night. Something came up and I won’t be home today until about 4:00 this afternoon.
    Can I wait until tomorrow to cook it? Not sure how long it can sit marinating.
    Thanks

    1. Katie Workman says:

      it can definitely marinate for 2 days, no problem! even better!

  7. Lucie L. says:

    In what kind of dish do you cook it? Pyrex, pan with holes or else. Sorry I don’t know the name in english.

    1. Katie Workman says:

      pyrex is fine, or any baking dish with sides, or even a roasting pan or a rimmed baking sheet – all good!

    2. Kristen says:

      Would this be good roasted in a cast iron skillet?

      1. Katie Workman says:

        if it’s large enough to hold the roast with space around it – yes!

      2. Anne says:

        When do you put potatoes, onions, and carrots in with the roast if you want those on the side?

      3. Katie Workman says:

        you can add them during the last two hours!

      4. Lila S Vandermay says:

        ALERT!!!! MUST TRY RECIPE!!!! I have googled so many recipes.. and yours stood out.. figured I would give it a try..and I am so glad I did.. Great recipe and great instructions… I personally don’t like rosemary so I just omitted it.. any suggestions for another herb? Maybe Oregano?
        Thank u for the GREAT RECIPE..

  8. Ellen says:

    I prepared the meat the day before, and followed the recipe. This is so flippin’ delicious! Every step was easy and effortless. Everyone loved it!!! The meat was so tender, juicy, and the flavor was on point! I was impressed! Definitely will cook again!!!

    1. Sydney S says:

      Have you ever made this in a slow cooker?

      1. Mia says:

        I used to make this roast in a slow cooker, and honestly it just isn’t as good. It doesn’t get the nice crust on it and almost is more like a stew meat. I found this recipe and tried it in the oven. I will NEVER slow cook this meat again. If you slow cook it, I would recommend doing it more as a BBQ type flavor.

  9. Tammy Narlock says:

    One word.. Amazing!!❤️

  10. Nora Garcia says:

    I am not a cook but I tried this and it was perfect! My whole family was thrilled with it. Had a smaller (<3lbs) pork shoulder and did 25mins at 450 then 3 hrs at 225. Came out juicy, tender and flavorful.
