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 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 the Pork Tenderloin is done?

If you have an Instant Read Meat Thermometer (affiliate link), I’d pull it out of the drawer for this 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 ingredients do you need for this recipe?

• pork tenderloin
• Pork Chop Seasoning (optional, but good)
• Garlic Powder (affiliate link)
• Kosher Salt (affiliate link)
• fresh-ground black pepper
• olive oil
• chicken broth (or water)
• spicy brown mustard
• Dijon mustard
• sour cream

How to make Pork Tenderloin with Mustard Sauce:

(Scroll down for complete recipe with nutritional information.)

1. Trim fat from the pork tenderloin pieces. (We cut them in half crosswide 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.

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.
