This pork tenderloin with apples, fennel, and leeks is an easy autumnal dinner you’ll want to have on repeat this season.

Apples add a pleasantly sweet tartness to this autumnal pork tenderloin recipe.
Nothing is better than a comforting meal that comes together in one skillet. This pork tenderloin with apples is just that. It’s a lightly sweet, savory pork recipe that doesn’t require much effort. If you’re going apple picking this season, you need to queue up this recipe to make! While I used Granny Smith apples, I’ve also made this recipe with sweeter red apples, and it’s just as delicious.


What you need
I love this recipe because you don’t need many ingredients.
- Pork tenderloin: I used pork tenderloin because they cook quickly, but you can make this with pork chops, chicken breasts, or bone-in, skin-on chicken thighs. You need to adjust the cooking time to accommodate whatever protein you use.
- Sauce: I make a simple sauce chicken broth, maple syrup, and Dijon mustard. This is similar to my very popular Pork Chops with Pears recipe!
- Aromatics: I sauté leeks, fennel, garlic, and a diced Granny Smith apple as the aromatic base for the pork tenderloin. They work beautifully together!
- Sweet vermouth: This is optional, but I love the sweet, savory flavor sweet vermouth brings to the dish. You can also use white wine, sherry, or Shaoxing wine.



How to make it
- Step 1: Prepare your ingredients. Pat the pork tenderloin dry and season it with salt and pepper. Whisk together the sauce ingredients and set them aside. Slice the leek and fennel, small-dice the apple, and mince the garlic.


- Step 2: Sear the pork tenderloin. Heat olive oil in a large, ovenproof skillet over medium-high heat. Add the tenderloin and cook without moving for 2 to 3 minutes. Flip and cook for 2 to 3 minutes until browned on the other side. Transfer to a plate.




- Step 3: Begin sautéing the aromatics in layers. Start with the leeks and fennel, then add garlic, and then add the apples. Deglaze the skillet with sweet vermouth or white wine.


- Step 4: Bake the pork. Add the prepared sauce to the skillet and bring to a boil. Place the pork tenderloin on top and bake at 400ºF for 12 to 15 minutes or until the tenderloin reaches your desired internal temperature. I recommend 135ºF.


- Step 5: Rest the pork. Remove the pork tenderloin from the oven and transfer to a cutting board. Rest for 5 minutes before slicing.


How to serve this pork tenderloin with apples
I slice the pork tenderloin into medallions and arrange the sliced tenderloin on a serving platter. From there, I spoon the sautéed apples, fennel, and leeks around the tenderloin. It makes for such a beautiful presentation!

What to serve with this pork tenderloin
I served it with a simple wild rice pilaf made with cranberries and almonds. Below are a few additional ideas for what to serve alongside this delicious fall dish!
- Sweet potato purée: This sweet potato purée recipe would be fantastic with the sweet, savory pork tenderloin.
- Butternut squash rice pilaf: Rice pilaf is so delicious with this, and my Butternut Squash Rice Pilaf recipe would add another layer of autumnal yumminess.

“This dish really delivered on flavor!
The sweetness from the apple really balances the pork. My house smelled incredible when I made the sauce. The Dijon and the maple syrup were a perfect pair!! I served this dish with mashed potatoes, and my family devoured it. I wouldn’t change a thing.
