What You’ll Need to Make Apple Pork Tenderloin in Oven
Just a few simple ingredients as a matter of fact and a cast iron skillet and you will be on your way to the glory of pork tenderloin with apples and brown sugar.
You could also prepare the dish using a slow cooker and we include instructions on how to do it in the recipe card.
- three large apples (such as Gala)
- pork tenderloin – about 2 lbs piece to serve 4
- two medium sized onions
- vegetable cooking oil and butter
- brown sugar, salt & pepper, ground cinnamon and one cinnamon stick (optional)
- apple cider/juice or pumpkin ale – you can make this dish year round and use apple cider or apple juice but when in season – we recommend pumpkin beer.
TIP: Pumpkin beer as the liquid of choice adds so much flavor. For this post we used Lakefront Brewery Inc. Spiced Pumpkin Lager (one of few pumpkin lagers brewed in the world, usually pumpkin beers are ales). It is very rich with intense spice notes and sweetness, yet dry and beautifully brings out the flavors of the pork.
NOTE: If cooking a larger piece of pork tenderloin you definitely need to use a larger heavy bottomed skillet and increase the rest of the ingredients (simply click on the servings number in the recipe card below and slide the bar, the ingredient amounts will adjust.
Mix the salt, pepper and ground cinnamon to create a rub for the pork tenderloin and set aside.
Peel and slice the apples (leaving the skin on a few slices is a good way to add a varying texture element; optional). Be sure not to slice them too thin because they will turn to mush during cooking.
Thinly slice the peeled onions.
NOTE: Before you proceed with the steps involving the apple pork tenderloin, we recommend that you remove the silverskin.
The silverskin is that thin, white membrane layer you can see in the ingredients picture above that covers the side toward the end of the pork tenderloin. It is helpful to remove it because it shrinks with heat and pulls on the pork causing it to twist in a bow shape.
Watch this excellent video demonstration on how to remove silverskin from pork tenderloin by our friend Jennifer from Seasons and Suppers.
Season the tenderloin liberally but not excessively on all sides with the salt, pepper and cinnamon rub.
Heat your cast iron skillet over medium high heat and add a tablespoon of cooking oil.
Then sear the pork tenderloin on all sides – about one minute per side. This will create a ‘seal’ and lock its juices in, ensuring it remains moist and flavorful during the cooking process.
Once the pork is seared remove it and set it aside while you turn your attention to the apples and onions.
Add a bit more cooking oil to the same skillet and cook the onions until translucent, then add the apples and mix them with the onions. Saute for 2 minutes.
Add the cinnamon stick (if using) then sprinkle brown sugar and stir.
Next comes our favorite moment – pour that pumpkin beer (or apple cider/juice) to deglaze the pan and form the base of the delicious sauce in which the dish will bake. Just love the sight of how the beer bubbles up … and the aromas, too.
Finally place the seared pork tenderloin back in the skillet and bake at 375 F.
The pork should be done in about 20 mins (a bit longer if you have a larger piece). Pork tenderloin doesn’t have to be cooked to 155 F like most other cuts or pork.
Look for internal pork tenderloin temp of 140-145 F when measured with food thermometer in the center of the meat.
Once out of the oven add the butter cut in small pieces on top of the apples and let it melt while you allow the pork to rest a little bit.
Take out the meat to slice it and baste the apples with the sauce in the pan (made silkier from the melted butter). Return the sliced pork to the skillet and serve.
Serve Family Style or Plate Individually
We made tandoori seasoning rice with sultana raisins to accompany our baked pork with apples and onions. The flavors complemented each other famously.
Since we are very low key most of the time we served the pork in the skillet to share family style. This dish however lends itself to elegant individual servings and the complex flavor profile it delivers certainly merits a fancier presentation.
TIP: To make the same rice as ours combine 1 cup of Jasmine or Basmati rice with 2 cups of water, 1 tbsp butter, 1 tsp of tandoori seasoning and 1/3 cup of sultana raisins in a pot. Stir, cover with lid and cook on medium heat until the water is absorbed (about 10 – 15 minutes). Remove from heat and let sit covered. Fluff with a fork right before serving.
