- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the Creamy Mashed Potatoes

- 1/2 cup whole milk (or half-and-half)
- 1/4 cup unsalted butter, softened
- 1/2 teaspoon salt (or more to taste)

Step-by-Step Instructions
-
Prepare the Pork Tenderloin
Preheat your oven to 400°F (200°C). Pat the pork tenderloin dry with paper towels. This helps achieve a better sear. Trim off any silverskin (the thin, silvery membrane) using a sharp knife. In a small bowl, mix together the dried thyme, garlic powder, onion powder, salt, and black pepper. Rub this seasoning mixture all over the pork tenderloin, ensuring it’s evenly coated.
Small tip: Removing the silverskin prevents the pork from curling during cooking and makes it more tender.
-
Sear the Pork
Heat the olive oil in a large, oven-safe skillet (cast iron works wonderfully here) over medium-high heat. Once the oil is shimmering, carefully place the seasoned pork tenderloin in the hot skillet. Sear the pork for 2-3 minutes on each side until it develops a beautiful golden-brown crust. You want a good color all around.
Small tip: Don’t move the pork around too much while searing. Let it develop that crust before flipping.
-
Roast the Pork
Once seared, transfer the skillet with the pork tenderloin directly into your preheated oven. Roast for 15-20 minutes, or until an instant-read thermometer inserted into the thickest part of the pork registers 145°F (63°C). The exact time will depend on the thickness of your tenderloin. Remove from the oven and transfer the pork to a cutting board. Tent it loosely with foil and let it rest for at least 5-10 minutes. This resting period is crucial for juicy pork.
Small tip: Resting the meat allows the juices to redistribute, ensuring a tender and flavorful result. Don’t skip this step!
-
Prepare the Potatoes
While the pork is roasting, place your peeled and quartered russet potatoes into a large pot. Cover them with cold water by about an inch. Add a generous pinch of salt to the water. Bring the water to a boil over high heat, then reduce the heat to medium and simmer until the potatoes are very tender when pierced with a fork, about 15-20 minutes.
Small tip: Starting potatoes in cold water ensures they cook evenly from the outside in.
-
Mash the Potatoes
Once tender, carefully drain the potatoes in a colander. Return the hot potatoes to the empty pot. Add the whole milk, softened butter, salt, and black pepper. Using a potato masher, mash the potatoes until they are smooth and creamy. Taste and adjust seasonings as needed. If you prefer them even creamier, you can add a tiny bit more warm milk.
Small tip: For the creamiest mashed potatoes, use warm milk and butter. Cold dairy can cool down the potatoes and make them gummy.
-
Make the Simple Pan Sauce
While the pork is resting, place the skillet you used for the pork back on the stovetop over medium heat. Add the chicken broth and Dijon mustard to the skillet. Use a wooden spoon or spatula to scrape up any browned bits from the bottom of the pan. These bits are full of flavor! Bring the sauce to a gentle simmer and cook for 2-3 minutes, or until it has slightly thickened. Taste and adjust seasoning if necessary.
Small tip: If the sauce reduces too much, you can add a splash more broth or even a tablespoon of water to reach your desired consistency.
-
Slice and Serve
Slice the rested pork tenderloin into 1/2-inch thick medallions. Arrange the sliced pork on plates alongside generous scoops of the creamy mashed potatoes. Drizzle the warm pan sauce over the pork. Garnish with fresh chopped parsley, if desired, for a touch of color and freshness. Serve immediately and enjoy your delicious meal!
Small tip: Slice the pork against the grain for the most tender bites.
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free! Just ensure your chicken broth is certified gluten-free, as some brands may contain hidden gluten.
- Vegan/Vegetarian Option: For a delicious plant-based meal, substitute the pork tenderloin with thick-cut roasted portobello mushrooms or cauliflower steaks. Use plant-based milk and vegan butter for the mashed potatoes, and vegetable broth for the pan sauce.
- Add More Vegetables or Protein: Roast some asparagus spears or green beans alongside the pork in the oven during the last 10-15 minutes of cooking. You can also add a side salad for extra greens and fiber.
- Spicy Version: For a kick, add a pinch of cayenne pepper to the pork seasoning rub. You can also stir in a dash of your favorite hot sauce to the pan sauce for an extra layer of heat.
- Herbaceous Flavor Boost: Experiment with different herbs! Add a sprig of fresh rosemary or a few sage leaves to the skillet while searing the pork. For the mashed potatoes, consider adding roasted garlic cloves or chives for extra flavor.
