What Makes This Recipe Work?
Pork makes such a great meal. It is economical, simple to make, and has great flavor. I made one with simple seasoning, and one with honey mustard.
This is so easy to make. It takes a few minutes to sear, and the rest is hands-off time. The ideal protein for a busy weekend meal or weekend meal prep.
I love cooking in cast iron, especially my pork. It is a great way to cook. It might just be an urban legend, but I have heard cooking in cast iron will help you get close to your daily iron intake. I used a my lodge cast iron skillet.
Ingredients
- Pork tenderloin- I cooked 2 for this recipe, but if you are feeding a smaller crowd, you can always cook one.
- Canola oil- this is used in the sear the meat. If you would like to use another oil, go for it, just make sure it can handle the heat!
- Salt, pepper, paprika, garlic powder, onion powder, black pepper, and cayenne pepper- this is the secret blend I ALWAYS use for my meats.
- Honey- for the honey mustard
- Mustard- I used plain yellow mustard, but you can also use Dijon or Stoneground mustard if you like it better.
- Cajun seasoning- I add this to my honey mustard.
How To Make
Preheat the oven. Mix your spices and sprinkle them over the pork tenderloin. Press the spices into the pork.
Heat your cast iron over medium heat until it is almost smoking. Then add the oil and swirl it around. Add the pork right away. Sear it on one side, then flip to the other and sear that side as well.
If you are going to make the pork tenderloin honey mustard, mix the honey, mustard, and spices. Pour half of it over the tenderloin and place in the oven.
After 5-7 minutes, pour the rest of the honey mustard over the tenderloin again. Continue to cook until it is done. I like mine rare or medium-rare, but you can cook it to 165 degrees if you prefer. Remove it from the oven.
Let it rest for a few minutes before slicing. Once it is sliced, it is ready to serve!
If you are looking for side dish ideas, let me suggest a couple I love. You can never beat a good twice-baked potato. Or what about a white bean salad.
Notes
- You can trim your tenderloin before cooking it. I don't do it, because I like to cook my meat with the fat on it and trim it later when I can. But, if you prefer, you can always trim it before cooking, especially that silver skin.
- I cook my pork in cast iron, it's my favorite method, but if you want, you can use any skillet you prefer. Just make sure it is oven safe too.
- Make sure your pan is hot, otherwise, you won't get a good sear.
- Make sure the oven is also preheated and hot when you move the tenderloin to it. It should go from hot to hot to keep up the cooking momentum.
- You don't have to make one honey mustard like I did, or you can make them both honey mustard. It is REALLY good if you are into it.
- If you want to use this for meal prep, make sure to not overcook it. Otherwise, when you reheat it, it will dry out. You can see the doneness of mine, this is perfect for reheating.
- You can thinly slice this and use it as it is, thinly sliced on sandwiches, buddha bowls, or wraps. It is versatile.

sounds good but need to ask is this thing done in 5 to 7 mins after searing? Love my case iron skillet
admin says
Hey Sam! So it is seared, and then moved to the oven and baked at 385 degrees for 5-10 minutes. All together it is about 20 minutes of cooking time, which is generally enough for cooking the tenderloin. Let me know if you have any other questions.
