If you always have a box of this quick flavor mix in your cupboards too, we can be friends. 😉 It has always been a favorite way to flavor our easy meatloaf recipe, and make beef roast with onion soup mix too. Mix it up with a bit of olive oil, coat the outside and you’re ready to get that baby tender.

I think when it comes to large hunks of meat like this, low and slow is a great way to cook it. The oven will dry it out a bit too much. This uses fresh or defrosted meat. If yours is still rock hard, follow our Instant Pot frozen pork roast recipe here.

Let’s talk a little bit about slow cooking shall we?? First off I have a few different varieties and I love them all. Each one has an occasion to be used like….

  1. This is my favorite 6 quart programmable one with a locking lid so it’s great for bringing to a potluck too.
  2. If you just want to serve a few appetizers you should get this one that sit side by side one another.
  3. I prefer not to use liners, but rather just spray olive oil inside before adding my food for easier cleanups.

Let me give you a peek of my pretty thang I bought recently. It goes with my kitchen so I can just leave it out on the countertop all the time. 😉


Slow Cooker Pork Roast

Sometimes I find these on sale at the store and I stock up. We have a large deep freezer in the garage so it’s a great way to save money and cut down on the amount of times I have to go to the store. Especially when it’s Winter and I’m very comfortable inside when it’s snowing, this is a huge help.

Having a QUICK prep time is another win. I like to get to work in the morning, and sometimes have to take off for the whole day. If I can throw dinner in to start cooking in less than 15 minutes I’m all about it. This is a really simple 4 ingredient recipe for those times.

Do you need liquid to cook pork in slow cooker?

If it is a very large piece like that, no. Believe it or not the little bit of olive oil will drip down and with the drippings from the meat that emit while it cooks you will have plenty to steam it essentially. At the end you can then thicken what’s at the bottom of the pot to make onion gravy if you wanted to as well.

With thinner pieces like our Crockpot pork chops I would add some broth to keep them moist though.

If you wanted even bolder flavors you could substitute the oil for balsamic vinegar instead. That turns out wonderful as well if you love the taste of that. Literally all you do is whisk together the packet, a bit of liquid, set meat inside, pour that on top and start.

Love onions? You can certainly cut up into thick slices and sprinkle those all over. A super inexpensive way to add a bit of texture. Keep in mind that the timing for this is based on a piece that was 3.5 pounds. If yours varies from there you would need to adjust the timing.

Since this is an easy pork recipe you will need to ensure it is cooked all the way thru before eating it. Unlike beef where you can cook it with a bit of pink left inside, you must use a thermometer to hit 145 degrees F internal meat temperature in the thickest part.

Note: Remember that you should always allow meat to rest at least 10 minutes before slicing. This will keep it tender and moist on the inside. Another thing to note is that it will continue cooking while it’s resting so if you take it out at 145 F it will likely rise another 5-10 degrees.

Slow Cooker Shredded Pork

SO don’t overcook the heck out it unless you want it broken down for shredded pork. For that I would suggest halfway thru the cook time to slice your hunk into 3-4 equal sized pieces. Submerge in liquid again and continue cooking covered. This will give it a better opportunity to break down and soak up the juices.

This is similar to what I do when making Instant Pot pork tacos. First I cut into smaller chunks so it can break down easier. You can either slice at the beginning and shorten the cook time, or wait until hour 4 or so and break it down then.

Can you overcook pork in slow cooker?

It’s hard to do so with all the fat in this meat. I mean anything can get dry after a really long time but typically this type of protein just gets more tender the longer it’s in there so you don’t have to worry about it as much as if you were making frozen chicken in Crockpot or something. That’s so lean it would be a problem.

This is what you’re going to need:

  1. Pork loin roast
    1. for tenderloin follow our pork tenderloin slow cooker recipe instead, it’s smaller
  2. 1 pkg dry onion soup mix
  3. A bit of olive oil, chicken stock, balsamic vinegar, or even red wine
  4. Fresh rosemary is a nice touch
  5. Slice an onion and add if you have it on hand

Like I said, if you want to slice it at the end, follow directions below as is. If you want it shredded then I usually slice the hunk into 4 equal pieces, pour sauce on everything, and check after 6 hours on low. I do not like cooking large pieces of protein on high, ever.

Onion Soup Mix Pork Recipe

This is how this easy recipe is to prep. There is a printable recipe card at the bottom of the post as well.

  • In a small dish whisk the onion soup mix and olive oil. Lay your piece of meat inside slow cooker
    • Pour this mixture over the top.
    • Sprinkle on rosemary.
    • If adding onions, slice and sprinkle slices around meat.
  • Close lid and slow cook on low for 8 hours.

You can serve these in small tortillas with red cabbage cole slaw on top as tacos, over a bed of white rice or as roast and vegetables with a side of red potatoes sprinkled with salt and pepper.

Another idea for this “paste” with your soup mix, you could make our baked pork chops and use this instead of our dry rub. Both are total comfort food x100.

Made this last night, and it was not good. Pork was bland and dry, despite having a lot of liquid. I'm going to try putting the rest of it in some chili to make it palatable.

This looks amazing. Can’t wait to try!

I like to read through new recipes. However, I don't see how you can call this a healthy meal with the sodium content at over 900 for 2 ounces!! I am sure it is delicious, as I used to make my meatloaf this way, but have had to cut back . Ever tried to get a good result with spices??

@fran, where does it say 900 mg of sodium in 2 oz?


Saturday 22nd of October 2022

@fran, I was thinking the same thing!! Nice idea but between the pork fat and sodium def not healthy.

I don't do those calculations, the recipe card does and I cannot verify how accurate that is. You could still use the onion soup mix with Mrs. Dash which doesn't have any sodium in it but a lot of flavor.
