I call recipes like this that cook in a skillet on the stove Skillet Meals, and I love them for a quick dinner! 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.

We devoured this pan-fried pork with mustard sauce 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 that won’t heat up the kitchen.

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 familiar with it. As long as you’re careful not to overcook the meat, pork tenderloin is easy to cook, and I love this recipe.

What mustard can you use for Pork Tenderloin with Mustard Sauce?

We used a combination of spicy brown mustard and Dijon mustard for the sauce in this recipe, but if you’re not a fan of those more pungent mustards, use any type of mustard you prefer.

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 pan-fried pork recipe. The USDA now recommends pork be cooked to 145F/63C, 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.

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 tenderloin has rested for 10 minutes, cut it into pieces about 3/4 inch thick and serve with the mustard sauce spooned over.
