Ingredients for pork tenderloin recipe with apple pie filling
Sweet-spiced apples and tender pork create a showstopping dish with minimal effort.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of fat |
| Granny Smith Apples 🍎 | 2 medium | Peeled, cored, diced small |
| Brown Sugar 🍚 | ½ cup | Packed, light variety |
| Old-Fashioned Rolled Oats 🌾 | ½ cup | Quick or old-fashioned |
| All-Purpose Flour 🌾 | ¼ cup | For streusel texture |
| Ground Cinnamon 🍃 | 1 ½ tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed |
| Granny Smith Applesauce 🍎 | ¼ cup | Unsweetened, for moisture |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |

The pork tenderloin is your canvas here—center-cut and trimmed for even cooking. Grab one from the butcher counter if you can, as they often have fresher cuts than packaged ones. I prefer 1.5 pounds for four servings, but adjust based on your appetite (this dish disappears fast). The apples? Granny Smiths—their tartness cuts through the richness, but Honeycrisp works too if you prefer sweetness. Peel and dice them small so they cook through without turning mushy. For the streusel, old-fashioned oats give the best texture, but quick oats in a pinch work fine.
No brown sugar? White sugar plus a pinch of molasses gets you close, though the color won’t be as rich. Short on applesauce? Unsweetened applesauce from a jar (like Mott’s) is fine, but homemade is better—just cook down peeled apples with a splash of water. The apple pie spice is non-negotiable here—it’s the magic behind that warm, cozy flavor. Making your own? Mix 1 tsp cinnamon, 0.5 tsp ginger, 0.25 tsp nutmeg, and 0.25 tsp allspice. For the butter, cold cubes are key—they create flaky layers in the streusel. If you’re in a rush, microwave for 20 seconds to soften slightly, but don’t melt it completely.
Prep the filling ahead—it keeps for 3 days in the fridge in an airtight container. The streusel topping? Make it 1 day ahead and store it in the freezer—it’ll be easier to crumble onto the pork when ready. The cooked pork stays 3-4 days in the fridge, but reheating is a must—350°F for 15 minutes with foil over it revives it perfectly. Freeze portions for up to 3 months if you’re planning ahead. Pro tip: Save the apple peels—toss them in a smoothie or compost them for your garden.

Step-by-step instructions for pork tenderloin with apple pie filling
Here's how to create a perfect balance of savory pork and sweet apple pie filling.
Prepare the Pork Tenderloin and Seasoning
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this ensures a good sear. Place it on a cutting board and make a few shallow slashes about ¼-inch deep on each side using a sharp knife. This helps the seasoning penetrate and prevents curling during cooking.
In a small bowl, combine 1.5 tsp ground cinnamon, 0.5 tsp salt, and 0.5 tsp ground black pepper. Rub this mixture all over the pork, pressing it into the slashes. Let the seasoned pork sit at room temperature for 15 minutes while you prepare the filling. This step guarantees maximum flavor penetration and even cooking.
Create the Apple Pie Filling
In a medium bowl, combine the 2 medium Granny Smith apples (already peeled, cored, and diced), 0.25 cup granny smith applesauce, 1 tbsp lemon juice, 1 tbsp honey, and 1 tsp apple pie spice. Stir gently to coat the apple pieces evenly. This mixture should be slightly chunky but well combined—you want the apples to retain their texture while absorbing the sweet-tart flavors.
Taste the filling and adjust the sweetness if needed. If the apples seem too tart, add a pinch more brown sugar (from the 0.5 cup total). The filling should balance bright apple acidity with just enough sweetness to complement the pork's savory notes.
Sear the Pork and Assemble the Dish
Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat until shimmering. Add the pork tenderloin and sear for 3-4 minutes per side until it develops a deep golden-brown crust. Remove the pork and set it aside on a plate.
In the same skillet, reduce heat to medium and add the 0.25 cup unsalted butter, 0.5 cup brown sugar, 0.5 cup old-fashioned rolled oats, and 0.25 cup all-purpose flour. Stir constantly for 1-2 minutes until the butter melts and the mixture forms a thick, crumbly streusel topping. This creates the signature sweet-spiced crust that will caramelize beautifully during baking.
Bake to Juicy Perfection
Return the pork to the skillet and spoon the apple pie filling over the top, pressing it gently into the slashes. The filling should cover about ¾ of the pork's surface, leaving room for the streusel to spread. Transfer the skillet to a 400°F preheated oven and bake for 20-25 minutes.
You'll know it's done when the pork reaches an internal temperature of 145°F (use a meat thermometer) and the streusel turns a rich golden brown with caramelized edges. The pork should be fork-tender with just a hint of pink in the center, and the filling should bubble gently around the edges.
Rest and Serve
Remove the skillet from the oven and let the pork rest for 5-10 minutes before serving. This resting period allows the juices to redistribute, ensuring each bite is moist and flavorful. The streusel will be slightly crisp on top but still tender underneath, creating the perfect textural contrast.
Slice the pork into ½-inch thick medallions and spoon the caramelized apple filling over each serving. The combination of tender pork, sweet-spiced apples, and buttery streusel makes this dish truly special. Serve with roasted vegetables or a simple side salad to complete the meal.
Pro Tips For Making Pork Tenderloin Recipe With Apple Pie Filling
- SEAR THE PORK FIRST: Hit the pork tenderloin with a screaming-hot pan—no need to wait for it to warm up. A deep sear locks in juices and builds flavor before the apples soften; I used to skip this and ended up with bland meat that just absorbed the pie filling.
- PEEL AND GRATE APPLES FINE: Granny Smiths stay tough when cooked, so peel and grate them on the large holes of a box grater—no need to dice. This creates a smoother filling that blends into the oat crust instead of turning mushy in spots.
- DON’T OVERMIX THE CRUST: The oat-flour crust is all about texture, so mix the dry ingredients just until combined—lumpy is fine. Overworking it turns the topping into a paste, and you’ll lose that perfect crunch you’re going for.
- REST THE PORK UNDER FOIL: After roasting, tent the pork with foil and let it sit for 5–10 minutes—yes, even if you’re starving. Skipping this step means juices pool on the cutting board instead of staying where they belong: inside the meat.
Pro cooking tips for this dish
Pork Prep Secrets
Always trim excess fat from the pork tenderloin—it renders differently than the lean meat and can make the filling uneven. I use a sharp boning knife to make ¼-inch deep slashes on each side before seasoning; this prevents curling during cooking and lets the filling seep deeper into the meat.
Let the seasoned pork rest at room temperature for 15 minutes—this ensures even cooking and maximum flavor penetration. 🔥
Streusel Texture Hacks
For the perfect streusel, pulse the oats, flour, and brown sugar together in a food processor for 10 seconds—this creates a finer, more uniform crumble that caramelizes beautifully. Use cold cubed butter (not melted) to maintain flaky layers.
If your streusel seems too dry, add 1 tbsp applesauce to the mix before baking. I swear by this trick for a tender, not crumbly, texture.
Filling Balance Tricks
Taste your apple filling before baking—if it tastes too tart, add ½ tsp extra brown sugar or ½ tsp honey. For extra depth, I sometimes fold in 1 tsp apple cider into the filling while it bakes.
The key is balance: you want the sweetness to complement the pork, not overpower it. A good rule of thumb is to aim for a filling that tastes like it belongs in a pie, not candy.
Oven Temperature Control
Preheat your oven to 400°F but place the skillet on the middle rack—this ensures even heat distribution. If your oven runs hot, reduce to 375°F and add 5 minutes to the baking time.
I always use an oven thermometer to verify accuracy. The pork is done at 145°F internal temp, but the streusel needs that golden color, so don't rush it.
Resting Like a Pro
Never skip the 5-10 minute rest after baking—this lets the juices redistribute, keeping every slice moist. I cover the pork loosely with foil to retain heat while resting.
For extra flavor, brush the sliced pork with warm apple cider before serving. This simple step transforms the dish from good to showstopping.
Make-Ahead Magic
Prepare the filling and streusel components 1 day ahead—store them separately in airtight containers in the fridge. The filling keeps for 3 days, while the streusel stays fresh for 2 days.
Assemble and bake fresh for the best texture, but you can reheat leftovers at 350°F for 15 minutes with foil over them. Freeze cooked portions for up to 3 months** for a quick meal later.

Frequently asked questions
Can I substitute regular apples for Granny Smith in the filling?
You can, but Granny Smith apples work best because their tartness balances the sweet streusel perfectly. For a sweeter version, try Honeycrisp or Fuji—just reduce the brown sugar by 1-2 tsp to avoid overpowering the pork. Avoid overly soft apples like Gala, as they'll turn mushy during baking.
How do I keep the pork tenderloin from drying out?
Never skip the 15-minute room temp rest before cooking—this ensures even cooking. Use a meat thermometer and remove the pork at 145°F internal temp (it'll rise to 150°F while resting). The apple pie filling adds moisture, but avoid overbaking—20-25 minutes at 400°F is ideal.
Can I make this dish ahead of time?
Prepare the filling and streusel 1 day ahead and store separately in airtight containers. Assemble and bake fresh for best texture, but leftovers reheat beautifully at 350°F for 15 minutes covered with foil. The pork stays juicy when reheated this way.
What's the best way to serve this dish?
Slice the pork into ½-inch medallions and spoon the caramelized filling over each serving. Pair with roasted Brussels sprouts or mashed sweet potatoes to balance the sweet-savory flavors. For a complete meal, add a simple arugula salad with apple cider vinaigrette.
Why does my streusel turn out crumbly instead of crisp?
Crumbly streusel usually means the butter was too warm when mixed. Use cold cubed butter and pulse the oats/flour/sugar briefly in a food processor for a finer texture. If it's still dry, add 1 tbsp applesauce to the streusel mixture before baking.
