Ruined roast?

I bought a 4 lb pork tenderloin this weekend and decided I was going to try this slow cooker recipe with it:

I did add a step to brine it last night...

So, it's been cooking on low now for about 5 hours, and I expected it to have 1 - 3 hours left to go, but... I just checked the meat temperature and it is around 180 and the meat is tough. I also check the vegies and the carrots and potatos still are not tender. I was a little skeptical, so I tried a different thermometer and got the same results../

Do I need to cook it longer? Pull the meat and let the vegies continue?

  1. veggies are on the bottom, right? Also, it may take 8 hours, don't lift the lid.

      Yes, vegies on the bottom, and I only lifted the lid long enough to probe it twice.

      I was just worried that since the meat temp is so high already, that cooking it longer was just going to make the meat tougher. I also stuck the probe down in the "sauce" to get a ready on what temp low is on my pot. Around 180 in the middle and higher as I lowered the probe towards the bottom.

        If it were a roast with lots of connective/collegen, then, yeah cook longer, but that's a pretty lean cut. You could hold it where it is, out of the slowcooker, and finish the veggies on high.

        1. re: THoey1963

          It's already overcooked so cooking it longer would make it even tougher. Pork tenderloin doesn't do well in the slow cooker to begin with and takes less time than the boston butt to cook. It'll be dry but you can slice it thin and across the grain to make it easier to eat.

          The Boston butt (in the blog) is very fatty, has connective tissue and does well w/ long slow cooking. The loin is less so and the tenderloin is very low fat and doesn't do well past 140 degrees. It's not one to use for braising.

      2. If it's 4 lbs, it's a loin, not a tenderloin. Either way, it's not a great cut for braising.

          This was also my thought. Neither cut does well as a braise.

            That's odd. I use pork loin (not tenderloin) exclusively for my pulled pork in the crockpot and it always comes out moist and tender and easy to shred. Not sure why others have a hard time with this cut of meat.

              I think it's personal preference on taste/texture. I prefer the fattier cuts of meat that do well w/ braising. Some like chicken breast that shreds easily and falls off the bone. I find it dry. No different from someone enjoying a well done sirloin vs a more rare rib eye--it's not in the difficulty cooking; it's in the taste preference.

              1. re: ludmilasdaughter

                I think chowser said it well -- I am not a fan of pork loin for pulled pork, but it's great that you make one that you like. It's not that someone is having a hard time with it - it's that the result isn't how we prefer it.

          2. pork tenderloin should never go in a crockpot. It's too lean and tender.

            A crockpot will destroy it.

            1. I think everyone else hit the nail on the head with it being the wrong cut for the crock pot. Just wanted to mention that I love that blog you pulled the recipe from. Mary has a lot of throwback recipes that remind me of my father's cooking. When I'm in a pinch and don't feel like thinking what to make my picky eaters, I go there.

              1. I cooked this in a slow cooker recently, using loin rather that tenderloin:


                I was worried that it would not be the right cut for this treatment, but I need not have feared as it worked really well. Easy to shred.

                So, as wyogal says, a few more hours may be the answer.

                  Is brining a good start for a braised pork loin?

                  1. re: sr44

                    Not sure about brining, and a pork loin is not a cut I would normally braise, but it worked fine for the pulled pork in that link. A pork loin, preferrably with skin on and bone in, makes a great roast though.

                    Actually I don't think that pork in general is a very braise/stew/cassreole friendly meat. There are some nice recipes of course, but for me beef, lamb and poultry make more enjoyable dishes of this type.

                    1. re: sr44

                      IMO brining is best for a dry heat cooked product, not a braise
