Truly-Tender Pork Tenderloin Recipe

Variations and Substitutions

A few easy swaps so you can work with what you have.

• Pork loin instead of tenderloin: To make this as roast pork loin, add 15 to 20 minutes to the bake time and check carefully with a thermometer for 145°F.
• Seasoning: Swap Italian seasoning for the dried thyme in the spice rub, or add a few additional spices (like a little cumin and coriander).
• Honey instead of maple syrup: Works well in the glaze. Same quantity.
• Pork tenderloin marinade: Skip the dry spice rub and marinate the pork in olive oil, garlic, soy sauce, and Dijon for up to 4 hours in the fridge instead. Pat dry before searing.
• Slow cooker: Rub the pork, place it in the slow cooker with 1/2 cup broth, and cook on low for 3 to 4 hours. Make the glaze separately on the stovetop.
• Instant Pot: Sear on sauté mode, then pressure cook on high for 3 minutes with a 10-minute natural release. Make the glaze separately on the stovetop while it rests.
• Grilled pork tenderloin: This spice rub is excellent on the grill. Cook over medium-high heat, turning often, until 145°F internal temperature.
• No Dijon: Grainy mustard or spicy brown mustard both work as substitutes in the glaze.

How to Make Pork Tenderloin in the Oven: An Easy Guide

Here’s exactly how to cook pork tenderloin in the oven from start to finish. It comes together in a few simple stages with one skillet doing most of the work.

Brine the Pork

Stir the boiling water, kosher salt, and brown sugar together until dissolved. Add the cold water, then submerge the tenderloin and brine 30 to 60 minutes at room temperature. Drain and pat the meat very dry with paper towels before moving on.

Prep the Oven and Pan

Heat the oven to 400°F. Place an oven-safe skillet on the stove over medium-high heat. Getting the pan properly hot before the pork goes in is what gives you that deep, even sear.

Apply the Spice Rub

Mix the smoked paprika, garlic powder, onion powder, black pepper, thyme, cayenne, and salt in a small bowl. Press the spice rub firmly all over the tenderloin, coating every side evenly. This crust is what gives the baked pork that savory color and flavor once it hits the hot pan.

Sear the Pork

Add 1 tbsp olive oil to the hot skillet. Sear the tenderloin 2 to 3 minutes per side until deeply browned all over. This is where roasted pork tenderloin gets its best flavor and color.

Roast to 145°F

Add 1 tbsp water to the skillet to prevent scorching, then transfer to the oven. Roast 15 to 25 minutes, checking with an instant-read thermometer starting at the 15-minute mark. Pull the pork at 145°F in the thickest part.

Rest the Pork

Transfer the pork to a rimmed baking sheet and rest 10 minutes before slicing. I know it’s tempting to cut right in, but resting is what keeps the meat juicy. Give it the full 10 minutes.

Make the Maple-Dijon Pan Glaze

Return the skillet to medium heat while the pork rests. Add butter and let it melt, froth, and turn a light caramel brown. Stir in the broth, Dijon, maple syrup, vinegar, and soy sauce, scraping up all the browned bits from the bottom of the pan.

Reduce and Thicken the Sauce

Bring the glaze to a boil, then simmer 5 minutes to reduce by about half. Whisk the cornstarch with cold water in a small bowl and stir it into the sauce. Simmer 30 to 60 seconds until thickened, then strain through a fine mesh strainer and add any resting juices from the pork.

Slice and Serve

Slice the pork into 1/2-inch medallions and fan them out on a serving plate. Spoon the maple-Dijon glaze generously over the top. Finish with a small pinch of salt if the sauce needs a little lift.

Make Ahead and Storage

You can prep parts of this recipe ahead to make dinner even faster on busy nights.

Storing Leftovers

• Fridge: Store leftover pork in an airtight container for up to 3 days.
• Keep the sauce separate: Store the maple-Dijon glaze in its own container so the pork doesn’t get soggy.
• Great for meal prep: Slice leftover pork tenderloin thin and use it in sandwiches, grain bowls, or salads the next day.

Freezing

• Whole or sliced: Wrap tightly in plastic wrap, then place in a freezer-safe bag. Freeze up to 3 months.
• Freeze the sauce separately: The maple-Dijon glaze freezes well in a small container or ice cube tray.
• Thaw overnight: Move the pork to the fridge the night before you plan to use it.

Reheating Pork Tenderloin

• Oven: Cover with foil and reheat at 300°F for 10 to 15 minutes. This keeps the slices from drying out.
• Microwave: Heat in short bursts at medium power. Add a splash of broth to the container to keep things moist.
• Don’t overheat: Pork tenderloin is lean and dries out quickly if reheated too aggressively or for too long.

Final Notes, Pro Tips + Science-Based Secrets

Here are the tips that make the biggest difference with this baked pork tenderloin recipe.

• Use an instant-read thermometer: It’s the most important tool for juicy, perfectly cooked oven roasted pork tenderloin. Pull at 145°F and rest 10 minutes. That’s the formula.
• Pat the pork very dry: The drier the surface before searing, the better the crust. Moisture is the enemy of browning.
• Quick brine even when short on time: Just 30 minutes in salted water seasons the meat from the inside out and helps it stay tender and juicy during the high-heat roast. It’s one of my favorite ways to ensure a great baked pork tenderloin.
• Brown the butter first: Letting the butter turn caramel before adding the glaze ingredients builds a nutty depth into the sauce. Don’t rush past that step.
• Strain the sauce with fine mesh strainer: It takes 10 seconds and gives you a silky, restaurant-quality glaze instead of a lumpy one.
• Remove the silver skin: That tough membrane on pork tenderloins won’t soften in the oven. Always remove it before brining for the best texture.
• One skillet, less cleanup: Sear, roast, and make the glaze all in the same pan. Fewer dishes and more flavor from the fond.
