There’s no need for dry overcooked pork tenderloin! With our simple method for cooking pork tenderloin, you will be rewarded with tender, flavorful pork. Based on all the reviews (see them below), you guys love this recipe! So let’s learn how to make it, shall we? By the way, if you love the combination of apples and onions with pork, take a look at our cheesy apple stuffed pork chops!
Pork tenderloin is quite lean with almost no fat. So keeping it moist and juicy inside can be tricky. That is unless you know a few secrets:
Before roasting, we always sear our pork tenderloins on all sides first. To do this, we pat the pork dry, rub with a little oil, and then season with salt. Throw it into a hot pan and sear all sides until golden brown, which adds color and lots of flavor. We do this with other proteins, too. Take a look at our Easy Lemon Chicken Thighs, before baking them in the oven, we sear them first.
Be careful not to overcook the tenderloins. We know that sounds obvious, but we’ve all been served overcooked (and dry) pork tenderloin, right? Here’s the deal. Keep your oven temperature high (we go for a 425-degree oven). Then roast the pork for 15 to 20 minutes.
When Is Pork Tenderloin Cooked?
We cook our pork — wether we are making tenderloin or pork chops — until an internal thermometer inserted into the thickest part registers between 145 and 150 degrees F (63 and 65 degrees C).
That guarantees that the pork will be juicy inside. It also means the meat will be slightly pink in the middle, which we don’t mind at all. If you’re not a fan of the pink, cook a little longer, but be careful not to overdo it.

Juicy Roasted Pork Tenderloin
The trick to flavorful and moist pork tenderloin is to sear the pork before roasting. In our recipe, the pork is seared and then is baked on top a bed of apples and onions. Most often, you will find that pork tenderloins are sold in packages with two tenderloins. One tenderloin should generously serve 2 people and most likely serve 3.
One note, “pork tenderloins” and “pork loin” are two different cuts of meat. Pork tenderloins are much thinner and take less time to cook.
Watch Us Make the Recipe
You Will Need
2 pork tenderloins (about 1 1/2-pounds each)
2 tablespoons vegetable oil, plus more as needed
1 1/2 teaspoons salt, plus more as needed
1 tablespoon Dijon mustard
1 tablespoon chopped fresh thyme leaves
1/4 teaspoon ground black pepper
2 apples, cored and sliced (we like Granny Smith, Golden Delicious or Braeburn)
2 onions, sliced
1 cup chicken stock, see our homemade chicken stock recipe
1 tablespoon butter
- Prepare Pork
1Heat oven to 425 degrees F. Trim each tenderloin of any silver skin (this can be tough when cooked). To do this, use a small sharp knife and slide the blade under and outward to remove it.
2Pat pork dry with paper towels and then rub with one tablespoon of the oil and 1 1/2 teaspoons of salt. Heat a tablespoon of oil in a heavy-bottomed oven-safe skillet over medium heat. When the oil is hot and shimmers, add the pork tenderloins and cook, occasionally turning, until evenly browned all over; about 12 minutes. Transfer to a large plate or cutting board. (The pork will not be cooked through).
- Prepare Apples and Onions
1Keep the pan used to sear the pork on the stove over medium heat. Check the pan, if it looks dry, add two to three teaspoons of additional oil. (If there is fat left in the pan from cooking the pork, there is no need to add extra oil).
2Add the apples and onions then cook, occasionally stirring, until lightly browned around edges, about 5 minutes. Stir in 1 teaspoon of thyme.
- To Finish
1Use a pastry brush (or use your fingers) to rub the seared pork all over with the mustard, 2 teaspoons of thyme, and the black pepper. Place the seared pork tenderloins on top of the apples and onions, and then slide into the oven.
2Roast 10 to 15 minutes or until an internal thermometer inserted into the thickest part registers between 145 and 150 degrees F. Transfer the pork to a large plate and cover with aluminum foil. Let rest about 10 minutes.
3While the pork rests, place the pan with apples and onions back onto the stove and turn heat to medium. Add chicken stock and use a wooden spoon to scrape the pan, lifting any brown bits from the bottom. Bring to a simmer and cook until reduced by half. Add butter and stir until melted.
4To serve, slice pork into 1-inch slices then serve on a bed of the apples and onions with pan sauce drizzled on top.
Adam and Joanne's Tips
- Side Dish Suggestions: You cannot go wrong with the classics like Our Favorite Homemade Mashed Potatoes or Cinnamon Roasted Butternut Squash.
- Update: Some reviewers felt the apples became a little too soft in this recipe. We don’t mind it since they turn into a lovely sauce, but if you are concerned, try cooking the apples and onions separately to the pork — just use two pans. This way you can roast the pork until done, while at the same time cooking the apples and onions until you’re happy with their texture — possibly a few minutes less than stated above.
