  1. Lay the tenderloin on a board covered in plastic wrap.
  2. Slice lengthwise, not all the way through. Aim for 2/3 deep.
  3. Open it like a book, cover with more wrap, then flatten evenly with a meat mallet or rolling pin.

The Joy of Cooking with Apples

Cooking with apples adds a delightful sweetness that balances the savory flavors of pork. Apples are versatile and work wonders in a variety of dishes, especially in fall-inspired recipes. In this tenderloin dish, they bring a freshness that’s both unexpected and comforting. Remember, choosing the right type of apple can make a big difference. For this recipe, go for varieties that hold up well to cooking, like Granny Smith or Honeycrisp. They add a perfect crunch and a burst of flavor to every bite.

Why This Recipe Works for Busy Weeknights

We all know how hectic weeknights can be. Between work, family obligations, and trying to squeeze in a bit of personal time, cooking a wholesome meal often seems like a daunting task. This is where our Apple and Walnut Stuffed Tenderloin comes into play. It’s a recipe that requires minimal preparation and offers maximum flavor. Plus, the cooking process is straightforward and doesn’t require constant attention. While the tenderloin is roasting, you can multitask — perhaps prepare a side dish or spend a few moments relaxing. This dish proves that gourmet doesn’t have to mean complicated or time-consuming.

Serving Suggestions to Elevate Your Meal

To turn this tenderloin into a feast, consider pairing it with side dishes that complement its rich flavors. A simple green salad dressed with a vinaigrette provides a refreshing contrast. For something heartier, roasted vegetables or a creamy mashed potato work wonderfully. And let’s not forget wine — a glass of Pinot Noir or a medium-bodied Merlot pairs beautifully with the tenderloin, enhancing both the meal and the dining experience. End the meal with a light dessert, perhaps a fruit sorbet or a slice of cheesecake, to round off this delightful culinary journey.

  • 3 tbsp olive oil divided
  • 1 small red onion diced
  • 2 medium apples peeled and diced
  • ¼ cup walnuts roughly chopped
  • 2 tbsp breadcrumbs
  • 1 tsp fresh thyme
  • 2 lbs pork tenderloin butterflied
  • 1 dash salt to taste
  • 1 dash black pepper to taste


  • Preheat the oven to 350°F.
  • Soak 6-8 toothpicks in a bowl of water. This is to prevent the toothpicks from burning in the oven.
  • Heat a tablespoon of olive oil in a large skillet and add in the onion and apples. Cook, stirring occasionally, until the onions become slightly soft and translucent, around 3-4 minutes.
  • Remove from heat and add in the walnuts, breadcrumbs, and fresh thyme. Season generously with salt and pepper to taste. Set aside.
  • Lay the pork tenderloin on a flat surface and cover with plastic wrap. Pound the meat with a meat mallet until around 1/2 inch thick.
  • Spread the apple and walnut mixture over the meat and tightly roll the tenderloin like a jellyroll. Secure with toothpicks. Brush the tenderloin with the remaining olive oil and season generously with salt and pepper on all sides.
  • Place the same skillet you used to cook the onion and apples on a high heat. 
  • Add the pork tenderloin to the hot skillet and sear until golden on all sides, around 5-6 minutes.
  • Transfer the tenderloin to the preheated oven and roast until fully cooked through in the middle, 20-30 minutes. The temperature in the thickest part of the meat should read 155°F with an instant read thermometer 
  • Remove from the oven. Cover loosely with foil and allow to rest for at least 15 minutes. Remove toothpicks, slice and serve. Enjoy!


Tip: Butterflying pork tenderloin allows it to cook quickly and evenly, making it a simple, easy weeknight meal choice. To butterfly, place tenderloin on a large piece of plastic wrap on cutting board. Make a slit, cutting lengthwise down the middle, being careful not to cut all the way through. Best results are achieved by cutting 2/3 of the way through, leaving 1/3 of the overall thickness of tenderloin. Open the tenderloin like a book. Cover with a 2nd sheet of plastic wrap and pound it out with the flat side of a meat mallet or press it out with a rolling pin to an even thickness.
