Roasted Pork Tenderloin Sandwich Recipe

This roasted pork tenderloin sandwich is a hearty, satisfying meal built on juicy, herb-crusted pork slices piled onto crusty bread with a bright, tangy mustard-mayo spread. The tenderloin roasts quickly at high heat, keeping the meat moist and tender, while the simple pan sauce doubles as a flavorful drizzle. It’s an easy weeknight dinner that feels special enough for a weekend lunch.

Ingredients

  • 1 pork tenderloin (about 1 lb / 450 g)
  • 2 tbsp olive oil, divided
  • 1 tsp kosher salt
  • 1/2 tsp black pepper
  • 1 tsp garlic powder
  • 1 tsp dried thyme
  • 1/2 tsp smoked paprika (optional)
  • 1/2 cup (120 ml) chicken or vegetable broth
  • 1 tbsp Dijon mustard
  • 1 tbsp honey or brown sugar
  • 4 sandwich rolls (ciabatta, hoagie, or baguette sections), split
  • 4 tbsp mayonnaise
  • 2 tsp Dijon mustard (for spread)
  • 1 cup (30 g) arugula or baby spinach
  • 1/2 red onion, thinly sliced (optional)

Instructions

  1. Preheat oven to 425°F (220°C). Pat the pork tenderloin dry with paper towels. Trim any silver skin or excess fat.
  2. In a small bowl, mix salt, pepper, garlic powder, thyme, and smoked paprika. Rub the spice mixture all over the pork.
  3. Heat 1 tbsp olive oil in an oven-safe skillet over medium-high heat. Sear the pork for 2-3 minutes per side until browned on all sides.
  4. Transfer the skillet to the oven. Roast until the internal temperature reaches 145°F (63°C) (USDA FSIS safe minimum for whole cuts of pork), about 15-20 minutes. Remove from oven and let rest on a cutting board for 5 minutes.
  5. While the pork rests, make the sauce: place the skillet over medium heat (careful—handle is hot). Add broth, scraping up any browned bits. Stir in 1 tbsp Dijon mustard and honey. Simmer for 2-3 minutes until slightly thickened. Remove from heat.
  6. In a small bowl, mix mayonnaise and 2 tsp Dijon mustard. Spread this mixture on the cut sides of the rolls.
  7. Slice the pork thinly against the grain. Pile onto the bottom halves of the rolls. Drizzle with the pan sauce. Top with arugula and red onion (if using). Close the sandwiches and serve warm.

Tips

  • Don’t overcook: Pork tenderloin is lean and dries out quickly. Use a meat thermometer and pull it at 145°F (63°C); the temperature will rise a few degrees during rest.
  • Substitutions: No Dijon? Use whole-grain mustard or yellow mustard. For a dairy-free spread, use vegan mayo. If you don’t have thyme, use oregano or rosemary.
  • Make ahead: The roasted pork can be cooked a day ahead and sliced. Store slices in the sauce to keep moist. Reheat gently in a skillet or microwave.
  • Common mistake: Slicing too thick or with the grain makes the meat chewy. Always slice against the grain, thinly.

Serving Suggestions

Serve these sandwiches with a side of crispy fries, a simple green salad, or roasted vegetables. For a heartier meal, add a cup of tomato soup or a pickle spear. They’re also great for picnics—wrap them tightly in foil to keep warm.

Variations

  • BBQ Pork Sandwich: Swap the Dijon-honey sauce for your favorite barbecue sauce and add coleslaw on top.
  • Spicy Version: Add a sliced jalapeño or a drizzle of sriracha mayo to the spread.
  • Cheesy Melt: After assembling, place the sandwiches under a broiler for 1-2 minutes with a slice of provolone or Swiss cheese on top.
  • Herb Crust: Add 1 tbsp chopped fresh rosemary or sage to the spice rub for extra flavor.

Storage and Reheating

Store leftover pork and sauce separately in airtight containers in the refrigerator for up to 3-4 days. The assembled sandwiches are best eaten immediately; if storing, keep the bread separate to avoid sogginess. To reheat, warm the pork slices in a skillet over medium heat with a splash of broth or water, covered, for 5-7 minutes, or microwave in 30-second bursts until hot. Toast the rolls before assembling again.

Frequently Asked Questions

Can I use pork loin instead of tenderloin? Yes, but pork loin is larger and leaner; adjust cooking time and use a thermometer to reach 145°F (63°C). Slice thinner, as loin can be drier.

How do I know when the pork is done without a thermometer? It’s risky, but if you cut into the thickest part, the juices should run clear and the meat should be slightly pink in the center—but a thermometer is the only reliable way to hit 145°F (63°C).

Can I grill the pork instead of roasting? Absolutely. Grill over medium-high heat for 12-15 minutes, turning occasionally, until it reaches 145°F (63°C). Let rest before slicing.

What bread works best? Crusty rolls like ciabatta, baguette, or sourdough hold up well. Avoid soft sandwich bread, which gets soggy from the sauce.

Can I freeze the cooked pork? Yes, slice and freeze in an airtight container with a little sauce for up to 2 months. Thaw overnight in the fridge and reheat gently.

Is the pan sauce necessary? It adds moisture and flavor, but you can skip it and use extra mustard-mayo spread or a drizzle of olive oil.
