I made these carnitas when I first started my blog. They were an instant family favorite. But… my photography needed a makeover. Here is the picture before:

I remember trying to take this picture. I had only been blogging for three months! It was in the hallway on the stairs. I didn’t know how to use my camera or turn off the flash! So I covered the flash with my hand and took the picture! ? I think it is safe to say I have come a long way. And learned how to use my camera a little better!
Anyway. Now that you have had a good laugh and realize that anything is possible, let’s talk about these carnitas.
If I am going to make shredded beef it has to be perfect. I don’t want the beef to be dry or chewy. It has to be melt in your mouth tender and full of flavor. That is why I LOVE this recipe!

This recipe is the perfect way to make beef carnitas for your family. You will not believe how amazing the flavor is and it is so tender. This is one of my husbands favorite recipes. In fact, he is devouring two as we speak.
The beef is so flavorful and juicy that it tastes great by itself. You can add minimal toppings to add some fresh flavors like avocado, diced tomatoes, or even some cilantro. These are AMAZING! I know that you are going to LOVE them just as much as our family does. 🙂

  1. I have made this recipe many times for family and for potluck and always tender and tasty! And so EASY!
    Thank you!

  2. I was so excited to try this recipe, and my house spelled delicious as it was cooking. The meat was so tender and fell apart easily. I was so dissapointed when I tried it and it was so bland. I’m not sure what went wrong 🙁

  3. I made this recipe for our Mexican Christmas dinner. It was amazing!! Left out peppers and just added all spices to the slow cooker, no rub. it turned out scrumptious….definitely a repeat.

    1. Alyssa probably used garlic powder, or granulated garlic, due to it being a rub.
      The recipe already calls for salt.

  4. What if you don’t have a slow cooker. I had one but couldn’t seem to get it to work right for me so I gave it away.I am old and used to doing things on top of stone or in the oven. Any suggestions

  5. I know this post was made a few years ago but I would like to offer small lesson in the Spanish language.
    Carnitas by definition is pork so what you are calling Beef Carnitas you are actually calling Beef Pork. This is actually more along the lines of Barbacoa.

  6. I made this for our dinner this evening. I only had a one pound shoulder roast beef and I used my rice cooker to make this. It is so flavorful and I skipped on the jalapeños, and it still was amazing. Thank for sharing this recipe. This is a keeper.

    1. If you are using a large slow cooker it may cook it faster, otherwise the cooking time should remain about the same.

  7. I’m having to use a different meat as well and worry that it will stick to the pot. Do you think, had you not added the broth, this would have been the case when you did it?
