Pork tenderloin vs pork loin

What’s the difference between pork tenderloin and pork loin? The loin is a large roast. It’s very white meat. It’s tender and juicy, not tough like a shoulder or butt roast that requires a long cooking time. It can be used in this recipe with no problem. It will taste amazing too.

Pork tenderloin is darker meat. More tender, but less fat, so you have to be careful not to cook it too long. It’s more flavorful than the loin roast too. They are smaller so you might want to use two. But we use free-range meat and it’s expensive. So I’m conservative with how much meat I put in anything.

Potatoes are one of my favorite things to grow and to eat, so I like to find things to add them to. Many casseroles have pasta or rice, and while they can be delicious, I far prefer potatoes or another vegetable over either of them any day.

You can use sweet potatoes, summer squash or winter squash for the potato layer if you prefer. You could also use eggplant as well. But I love the combination of potatoes and green beans. Oh my, nothing says spring like fresh potatoes and green beans from the garden. New potatoes would be great in this recipe.

The first time I ever cooked a pork tenderloin I fell in love and that love has only grown stronger with each one I’ve cooked. My favorite flavor profile is bacon and dijon mustard, so I like to try it with different things using those. 

This dill and provolone combo along with the bacon and mustard was amazing. One of the best things I’ve ever made! Pork, green beans and potatoes. What could go wrong? Not much, but so much can go right!

What to do with leftover pork tenderloin

If you have some leftover pork tenderloin, pork roast, pork loin or pork chops even, you could make this recipe without the meat and add your leftover meat into it after so it doesn’t get overdone.

Leftover pork is a great resource because it’s so versatile. Check out how I cook one pork roast and make it into 5 meals. So good. 

You could also use leftover pork tenderloin by cubing it up and making it into tacos or topping a yummy baked potato with it. It would be awesome in breakfast hash too. There are unlimited possibilities with pork tenderloin because it has so much flavor and it’s so tender.

  1. In the recipe, Step 14 says: ‘Set instant pot on manual for 2 minutes’. I’m thinking this is a typo and should say ‘Set instant pot on manual for 20 minutes’.

    1. Hi Roxanne,
      The instant pot takes about 10 minutes to heat up before it’s to temp and then it cooks longer as it releases pressure. Overall, it’s cooking for about 20 minutes if you set it to 2 minutes. Thank you for checking though! And thanks for checking out the recipe.
