How Long to Cook Pork Tenderloin Medallions in a Pan

Pork tenderloin medallions are crosswise slices of tenderloin, seared in a hot skillet until browned and juicy. For slices about 1 inch thick, plan on roughly 3–4 minutes on the first side and 2–4 minutes on the second, then check each piece with a thermometer and rest the pork for 3 minutes.

This quick stovetop method pairs the pork with a simple lemon-Dijon pan sauce. Medallions are small, so thickness and skillet heat matter more than the clock: use the timing as a guide, and let the thermometer determine when they are done.

Ingredients

1 pork tenderloin, about 1½ lb (680 g), trimmed of silverskin
¾ tsp fine salt (about 4 g)
½ tsp freshly ground black pepper (about 1 g)
1 tbsp neutral cooking oil (15 ml), such as canola or avocado oil
1 tbsp unsalted butter (14 g)
2 garlic cloves, finely chopped (about 6 g)
½ cup low-sodium chicken broth (120 ml)
1 tsp Dijon mustard (5 g)
1 tbsp fresh lemon juice (15 ml)
1 tbsp chopped fresh parsley (about 4 g), plus more for serving if desired

Instructions

Prepare the tenderloin. Pat the pork dry with paper towels. If there is a thin, shiny membrane along the meat, slide a small sharp knife underneath it and trim it away; it can tighten as it cooks. Cut the tenderloin crosswise into medallions about 1 inch (2.5 cm) thick. If the tapered tail end is much thinner, fold it under itself or cut it into slightly thicker pieces so it is less likely to overcook. Season all sides with the salt and pepper. Letting the meat sit while the skillet heats is fine, but do not leave raw pork at room temperature for more than 2 hours.
Heat the skillet. Set a large, heavy skillet over medium-high heat for about 2 minutes. Add the oil and swirl to coat the base. It should look fluid and shimmer, but it should not smoke heavily. Arrange the medallions in a single layer with a little space between them. If they will not fit without crowding, cook in two batches; a crowded pan releases moisture and can steam the meat instead of browning it.
Sear the first side. Leave the pork undisturbed for about 3–4 minutes, until the underside has a deep golden-brown crust and releases fairly easily from the pan. If it sticks firmly, give it another 30 seconds rather than pulling it loose. Browning varies with pan material, burner strength, and slice thickness, so begin checking the timing early if your medallions are thinner than 1 inch.
Turn and cook to temperature. Flip each piece and cook for about 2–4 minutes on the second side. Start checking the thickest medallions with an instant-read thermometer after about 2 minutes; insert the probe sideways into the center for a reliable reading. The USDA FSIS safe minimum for whole cuts of pork is 145°F (63°C), followed by a 3-minute rest. Transfer medallions that reach the target to a clean plate; if some pieces are thicker, leave those in the skillet and check them again rather than keeping the whole batch cooking.
Rest the pork. Loosely cover the plate with foil and let the medallions rest for 3 minutes. The temperature and rest are important even when the meat looks browned outside. Pork cooked to 145°F (63°C) can remain slightly pink in the center; color alone is not a dependable doneness test. If cooking in batches, keep the first batch on the plate while the second cooks, then give the pork its full rest before serving.
Make the quick pan sauce. Once the pork is out, lower the heat to medium and add the butter. When it melts, stir in the garlic and cook for about 20–30 seconds, just until fragrant. Pour in the broth and scrape up the browned bits with a wooden spoon. Stir in the Dijon and simmer for 1–2 minutes, until the liquid is lightly reduced. Take the pan off the heat, mix in the lemon juice and parsley, and taste before adding more salt or pepper. Spoon the sauce over the rested medallions and serve.

Tips

Slice evenly. A consistent thickness helps the pieces finish together. If the tenderloin is very narrow at one end, cut that portion a little thicker or fold it under; thin pieces can reach 145°F quickly while thicker ones are still cooking.
Choose the right pan and avoid crowding. Stainless steel or cast iron browns well, but a heavy nonstick skillet also works; use a utensil that will not scratch its surface. If the pan is small, cook in batches and add a little more oil only if the surface looks dry. Let the pan regain heat between batches.
Use a thermometer rather than relying on appearance. A pork medallion can brown in less time than expected, particularly on a powerful burner. Check the center of several of the thickest slices and remove each piece as it reaches the safe minimum, then let it rest for 3 minutes.
Adjust the sauce to your pantry. Vegetable broth can replace chicken broth without changing the method, though the sauce may taste a little less savory. If you do not have Dijon, use 1 teaspoon (5 g) of whole-grain mustard for a textured sauce; ordinary yellow mustard is sharper and milder in complexity, so start with ½ teaspoon (2.5 g) and taste.

Serving Suggestions

Serve the medallions soon after resting, with the pan sauce spooned over the top or passed at the table. Their mild flavor works well with mashed potatoes, roasted potatoes, buttered egg noodles, rice, or crusty bread to catch the lemony sauce. For a lighter plate, add a crisp green salad, steamed green beans, sautéed spinach, or roasted broccoli. A vegetable cooked in the same skillet before making the sauce can also make the meal feel complete; transfer it to a plate first so the pork has room to sear.

If you are serving a group, arrange the medallions on a warm platter and spoon only some of the sauce over them so the browned surfaces remain visible. Put extra sauce in a small bowl. Keep the pork in a single layer rather than stacking it, which helps the pieces stay warm without trapping steam against the crust. A little extra chopped parsley or a few lemon wedges add freshness, but they are optional.

Variations

Herb and garlic: Add 1 teaspoon (about 1 g) of dried thyme or rosemary to the salt and pepper, or stir 1 tablespoon (about 3 g) of chopped fresh herbs into the sauce. Dried herbs are more concentrated, so use less than you would of fresh ones. Rosemary is especially assertive; use a small amount if you want the pork to remain the main flavor.

Apple-Dijon: Replace half the broth with unsweetened apple juice or cider, keeping the total liquid at ½ cup (120 ml). Simmer it with the Dijon until lightly reduced. The sauce will be fruitier and sweeter, so taste before adding lemon; a small squeeze can balance it if needed.

Creamy skillet sauce: After reducing the broth, stir in 2 tablespoons (30 ml) of heavy cream and warm gently for about a minute. Avoid a hard boil after adding cream. For a dairy-free version, leave out the butter and use another tablespoon (15 ml) of oil, then keep the broth-based sauce as written.

Spiced medallions: Add ½ teaspoon (about 1 g) smoked paprika or ground cumin to the seasoning. Either gives the crust a warmer, more savory character without changing the cooking method. Keep the mustard-lemon sauce, or omit the parsley and finish with chopped cilantro if that suits the seasoning.

Storage and Reheating

Refrigerate leftover pork within 2 hours of cooking, storing it in a shallow airtight container with any remaining sauce. Cooked pork keeps for 3–4 days in the refrigerator. For longer storage, freeze it in a freezer-safe container for up to 2–3 months for best quality; thaw it in the refrigerator rather than on the counter. The texture may be a little less juicy after freezing, so save enough sauce to serve with it.

For the best texture, reheat medallions gently in a covered skillet over low heat with a spoonful or two of broth or water. Turn them once and heat until the center reaches 165°F (74°C), the USDA FSIS temperature for reheated leftovers. A microwave also works: cover the pork, add a little sauce or liquid, and heat in short intervals, turning the pieces between intervals so they warm evenly. Avoid prolonged high heat, which can dry out lean tenderloin. Reheat only the portion you plan to eat.

Frequently Asked Questions

How long do ½-inch pork tenderloin medallions take to cook?

Thin medallions may take about 2–3 minutes on the first side and 1–3 minutes on the second in a hot skillet, but the exact time depends on heat and thickness. Start checking early with an instant-read thermometer and remove each piece when its center reaches 145°F (63°C), then rest it for 3 minutes. Thin slices can overcook quickly, so do not wait for a particular time if the thermometer shows they are ready.

Can I cook pork medallions in the oven instead?

Yes. Sear the medallions briefly in an oven-safe skillet, then transfer the skillet to an oven heated to 400°F (204°C) to finish cooking. The oven time depends on slice thickness and how long they were seared, so begin checking the centers after a few minutes rather than relying on a fixed finish time. Cook to 145°F (63°C) and rest for 3 minutes. If you do not have an oven-safe skillet, move the seared pieces to a baking dish.

Why are my pork medallions tough or dry?

The most common cause is cooking them beyond the safe temperature for longer than necessary. Tenderloin is lean, and thin pieces can go from juicy to dry quickly, especially in a very hot pan. Cut the slices evenly, check the thickest pieces with a thermometer, remove them as they reach 145°F (63°C), and allow the required 3-minute rest. Crowding can also interfere with browning and encourage uneven cooking.

Is pork safe to eat if it is a little pink inside?

It can be. Color is affected by several factors and does not reliably tell you whether pork is safely cooked. For whole cuts such as tenderloin, use a food thermometer to verify 145°F (63°C) at the center and then rest the meat for 3 minutes. Properly cooked pork may still show a blush of pink; use the measured temperature, not color or clear juices, as your guide.

Can I season the pork ahead of time?

You can salt and pepper the medallions up to a day ahead and keep them covered in the refrigerator. Pat the surface dry before searing so moisture does not hinder browning. For the best crust, wait to add the oil until the skillet is hot, and do not leave seasoned raw pork at room temperature for more than 2 hours. If you prepare the slices in advance, keep them refrigerated until you are ready to cook.
