Instructions

Prepare the Stuffing: In a large skillet, heat the butter and oil over medium-high heat. Cook the mushrooms and onions (or shallot), stirring occasionally, until the liquid is evaporated, about 8 minutes.
Add the remaining vegetables: Add the apple and carrot to the skillet. Cook for 1 minute.
Combine the stuffing: Remove the skillet from the heat. Add the bread crumbs, parsley, thyme, sage, mustard, salt, and pepper to the skillet. Mix well to combine all ingredients.
Set the stuffing aside: Set the prepared stuffing aside.
Prepare the Pork Tenderloin: Cut each pork tenderloin lengthwise halfway through, but don’t cut all the way through. Open the tenderloin like a book.
Pound the pork: Place the opened pork tenderloin between sheets of plastic wrap or waxed paper. Using a meat pounder or rolling pin, pound the pork to a generous ¼-inch thickness. This evens out the meat and makes it easier to stuff and roll.
Prepare the Roasting Pan: Cut about 7 pieces of kitchen string into 15-inch lengths. Arrange the string crosswise about 1 ½ inches apart in a lightly greased roasting pan.
Assemble the First Layer: Place 1 piece of the pounded pork on the strings in the prepared roasting pan.
Stuff the Pork: Using your hands, press half of the stuffing over the pork to completely cover the surface.
Add the Second Layer: Top with a second piece of the pork, placing the wide end of the second piece over the thin end of the first piece. Tuck the thin ends under and press firmly in place to create an even layer.
Complete the Stuffing: Top with the remaining stuffing and the last piece of pork.
Tie the Roast: Tie the strings around the roast, trimming any excess string. Ensure the roast is securely held together.
Season the Roast: Spread the Dijon mustard evenly all over the roast.
Add the Apple Topping: Arrange the apple slices in a lengthwise row on top of the roast. Sprinkle with the remaining salt and pepper.
Bake the Roast: Place the roasting pan in a 400°F (200°C) oven. Immediately reduce the heat to 350°F (175°C) and roast until a meat thermometer registers 160°F (71°C), approximately 1 ¼ to 1 ¾ hours. The exact cooking time will depend on the thickness of the roast.
Rest the Roast: Transfer the roast to a cutting board. Tent with foil and let stand for 10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful roast.
Make-Ahead Option: For a make-ahead option, let the cooked roast cool completely, then cover and refrigerate for up to 24 hours before slicing and serving.
Prepare the Garnish: Cut the uncored apples crosswise into scant ½-inch thick slices. Discard the ends. Repeat with the red onion.
Sear the Garnish: In a large skillet, heat half of the vegetable oil over medium-high heat. Sear the apples and onion until browned, 1 to 2 minutes per side, adding more oil if necessary. This adds a beautiful caramelized flavor and visual appeal to the dish.
Slice and Serve: Slice the roast and arrange on a platter. Surround with the pan-seared onion and apples to serve.

Expert Tips & Tricks

Bread Crumbs: Using stale or slightly dried bread crumbs works best for the stuffing, as they absorb the flavors without becoming mushy.
Pork Doneness: A meat thermometer is essential for ensuring the pork is cooked to a safe and optimal temperature. Insert the thermometer into the thickest part of the roast, avoiding the stuffing.
Stuffing Variations: Feel free to customize the stuffing with other ingredients like dried cranberries, chopped pecans, or different herbs like rosemary.
Searing the Pork: For an even deeper flavor, you can sear the outside of the pork tenderloin before stuffing it. This creates a beautiful crust and seals in the juices. Just be sure to reduce the overall cooking time slightly.
Deglaze the Pan: After searing the apples and onions, deglaze the pan with a splash of balsamic vinegar or apple cider vinegar to create a simple sauce to drizzle over the pork.

Serving & Storage Suggestions

Serve the Pork Tenderloin with Mushroom Stuffing & Pan-Seared Onion & Apple immediately after slicing for the best flavor and texture. The dish pairs beautifully with roasted vegetables like Brussels sprouts or asparagus, or a side of mashed sweet potatoes.

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.

Reheating: To reheat, slice the pork and arrange it on a baking sheet. Cover with foil and bake at 325°F (160°C) until heated through. You can also reheat individual slices in the microwave. Reheat the pan-seared apples and onions separately in a skillet until warmed.

FAQs (Frequently Asked Questions)

A: Yes, you can prepare the stuffing a day in advance and store it in the refrigerator. This can save you time on the day you plan to cook the pork tenderloin.

Q: How do I prevent the pork from drying out during cooking?
A: Be sure not to overcook the pork. Use a meat thermometer to ensure it reaches an internal temperature of 160°F (71°C). Tenting the roast with foil while it rests also helps to retain moisture.
