🐖 What is pork tenderloin?
Pork tenderloin is known as the "filet mignon" of pork. It's a thin, boneless cut from along the backbone that is best cooked quickly to avoid overcooking. It is often confused with a pork loin, which is a very different, thicker cut of meat that should not be substituted.
🍳 Why use a cast iron skillet?
Using a cast iron pan when cooking pork tenderloin will allow you to get a nice golden sear on the outside, then finish baking it all in the same pan. The searing process adds lots of flavor, you'll use limited dishes, and clean up is minimal.
For my favorite cast iron skillets (affiliate) and instructions for seasoning and cleaning cast iron, check out our Cast Iron Skillet Guide.
🍯 Ingredients
- Pork tenderloins: These often come in packs of two and one is usually smaller than the other. Choose tenderloins that have pinkish-red flesh and some marbling of fat throughout.
- Creole seasoning: Our favorite is Tony Chachere's Original Creole Seasoning (affiliate). It's a perfect blend of garlic powder, black pepper, salt, and other spices.
- Dried thyme: Fresh thyme can be substituted, but I actually prefer dry in this recipe.
- Butter: A little butter brings the sauce to life. I use salted, but you can always add a touch of salt if you use unsalted butter.
- Honey: Adds just a bit of sweet to compliment the seasonings.
🔪 How to make cast iron pork tenderloin
Start by trimming the silver skin off of your tenderloins (see more details in the FAQ section). Combine the creole seasoning and thyme in a small bowl, then sprinkle it evenly on all sides of the pork.
Heat 1 tablespoon oil in a cast iron skillet over medium high heat. Once hot, sear each side of the pork for 3-5 minutes, until golden brown.
Add the honey and butter straight to the pan. Roll the tenderloins around to coat in sauce. Bake in a preheated oven at 375°F for 15-20 minutes, or until a meat thermometer registers the internal temperature at 145°F. You may need to remove the smaller one sooner, then continue cooking the larger one.
Remove meat from the hot pan and let pork rest for 5-10 minutes tented loosely with aluminum foil. Meanwhile, if the sauce is too thin place it over medium heat and simmer until slightly thickened. Slice the rested pork and serve with sauce.
🥗 Serving ideas
Cast Iron Pork Tenderloin is the perfect recipe to serve with any number of sides! Roasted veggies, baby potatoes, fresh bread, and a quick salad make for a full meal.
Our favorite sides for this meal include Crispy Hasselback Potatoes, Perfectly Roasted Broccoli, Roasted Frozen Corn, Buttery Pull Apart Bread, and this Autumn Chopped Salad.
👨👩👧👦 For a crowd
If you want to serve this to more than 6-8 people, you will have to use two large skillets. Triple check that they fit in your oven at the same time. If they do, you're good to go!
🙋 Questions & Answers
You will likely find a layer of silvery-white connective tissue on your pork tenderloin. This is the silver skin. When cooked, silver skin shrinks oddly and becomes very tough and unpleasant to eat.
Before cooking, remove the silver skin by placing the meat on a cutting board and using a sharp knife to trim it off as you would a thick layer of fat.
The safe temperature for pork tenderloin is anywhere between 145-160 degrees F. Pork tenderloin can be slightly pink inside, but should not be dark pink or bloody. This article is a great guide for different temperatures.
We use this instant read thermometer (affiliate) to test it periodically as it bakes. We prefer to remove ours at 145° knowing that it will continue to cook slightly as it rests. This way it stays moist and tender!
Cast iron is preferred, but you could also use a dutch oven or oven-safe skillet.
Store your cooked pork tenderloin in an airtight container in the fridge for up to 5 days. Reheat gently in the microwave (I suggest 50% power to avoid drying it out) or in a wam skillet on the stove.
You can trim the meat and remove the silverskin, then store in the fridge wrapped tightly in plastic wrap for up to 3 days. If you need it to last longer, add a layer of tinfoil and freeze it for up to 3 months. Thaw completely before cooking.
👨🏼🍳 Tips & Tricks
- Pork tenderloin comes in different shapes and sizes. It doesn't usually have just two defined sides… sometimes it has 3 or even 4. Make sure to season and sear every side for the best results.
- Keep the skillet over a medium-high heat while searing, but turn it down slightly if you notice excessive smoke or burning.
- Check the temperature often to ensure you don't overbake the pork. If one tenderloin is smaller than the other, you may need to remove it sooner while the larger tenderloin finishes cooking.
