Recently I noticed this very tasty recipe for Pork Tenderloin with Mustard Sauce back in the archives with a photo that probably wouldn’t have enticed you to make it. So I made it again and took some better photos to encourage you to try this ultra-easy pan-fried pork recipe that’s low-carb and super quick to make for dinner. And if you happen to be a mustard fan you’ll love the creamy mustard sauce served on the pork!

Recipes like this one that cook in a skillet on top of the stove are what I call Skillet Meals, and I love stove-top dinners or main dishes for a quick meal! Of course I always like to “improve” a recipe when I’m taking new photos, but the only thing I changed for this easy pork tenderloin recipe was to be a little more specific about the spices to rub on the pork and to slightly increase the sauce ingredients, because I love the mustardy sauce.

We devoured it when we tested the recipe and took the new photos; if you like these ingredients I hope you’ll try this soon for an easy dinner.

What is Pork Tenderloin?

Pork Tenderloin is an extra-lean cut of pork that’s usually sold in packs of two with a total weight of about two pounds. Tenderloin is not the same as pork loin, so read that information if you’re not clear about that. As long as you’re careful not to overcook the meat, pork tenderloin is easy to cook, and I love this recipe.

How can you be sure Pork Tenderloin is done?

If you have an Instant Read Meat Thermometer (affiliate link), I’d pull it out of the drawer for this pan-fried pork tenderloin recipe. The USDA now recommends pork be cooked to 145F/63C, and if you take this off the heat when it reaches that temperature and let it rest for ten minutes, the pork will be juicy and tender.

What mustard did we use for the Pork Tenderloin with Mustard Sauce?

I used both spicy brown mustard and Dijon for the creamy mustard sauce served with this pork tenderloin, but you can use any types of mustard you prefer.

How to make Pork Tenderloin with Mustard Sauce:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  1. Trim fat from the pork tenderloin pieces. (We cut them in half crosswise to fit into the pan better.)
  2. Season the pork with Pork Chop Seasoning (if using), garlic powder, salt, and fresh-ground black pepper.
  3. Heat the oil in a large heavy skillet, and brown the pork over medium heat until it’s nicely browned on all sides.
  4. Then cover the pan, lower the heat to medium low, and cook until the temperature reaches 145F/62C.
  5. This took about 20 minutes for us, put the pork on a plate and cover tightly with foil to keep it warm. Let pork rest for 10 minutes while you make the sauce.
  6. Mix sour cream and both mustards, and taste to see if the mustard flavor is as strong as you’d like it.
  7. Using medium heat, deglaze the pan with the chicken broth (or water), scraping off any browned bits. 
  8. Then lower heat and add mustard-sour cream sauce and accumulated juice that’s on the plate, whisking it into the sauce.
  9. Simmer for a few minutes until the sauce is hot.
  10. When the pork has rested for 10 minutes, cut it into pieces about 3/4 inch thick and serve with sauce spooned over.

Instructions

  5. Lower heat to medium low, cover the pan and cook until the temperature of the pork reaches 145F/62C.
  6. This will take about 20 minutes, but for best results use an Instant Read Meat Thermometer (affiliate link) to tell when pork reaches that temperature.

  8. Mix together the sour cream, spicy brown mustard, and Dijon mustard, and taste to see if the flavor is as strong as you'd like.

  10. Then lower heat and add mustard-sour cream sauce and any accumulated juice that's on the plate where the pork is resting, whisking it into the sauce.
  11. Cook sauce for a few minutes to heat through, adding a little water if the sauce seems too thick.
  12. After ten minutes of resting time, slice the pork into pieces about 3/4 inch thick.
  13. Serve sliced pork with the sauce spooned over.

Notes

I'm a huge fan of Penzey's Pork Chop Seasoning and I'd use that for this recipe, but even if you don't have that this will still be tasty.
