Grilled Pork Tenderloin Sandwich Recipe

Grilled pork tenderloin sandwiches marinated in Italian dressing, grilled, and finished with provolone, grilled red onion, BBQ sauce, and dill pickles — a flavorful change from your usual burger or chicken sandwich.

I don’t cook pork tenderloin as often as other cuts like chops, ribs, or pulled pork, but when prepared this way it’s hard not to reach for seconds. The tenderloin pieces are cut, pounded thin, marinated in Italian dressing to boost flavor, then quickly grilled. Paired with toasted ciabatta or torta rolls, melted provolone, grilled red onion, tangy barbecue sauce, and dill pickles, these sandwiches deliver a satisfying combination of savory, sweet, and bright flavors.

To prepare, trim and slice each tenderloin into 2–3 inch pieces. Stand each piece on its side with the cut surface facing up and pound to about 1/2 inch thickness — this creates a thin, even “steak” that grills quickly and stays tender. I typically use two pieces per sandwich, but adjust the amount to your preference and the size of your rolls.

Pork tenderloin has a mild flavor, which makes it ideal for marinating. I use a robust bottled Italian dressing to add acidity and herbs; it’s an easy, reliable shortcut that infuses the meat without complicated prep. Marinate the pounded pieces in a single layer, coating each piece well, and chill for 2–3 hours so the flavors develop and the meat tenderizes slightly.

When you’re ready to grill, preheat to medium-high. Remove the tenderloin pieces from the marinade and let any excess drip off. Slice a red onion thinly, toss the slices with a little olive oil, salt, and pepper, and place them on the grill alongside the pork. Toast split torta or ciabatta rolls lightly on the grill so they’re warm and slightly crisp.

Grill the pork about 3–4 minutes per side, depending on thickness, until cooked through and just browned. Lay a slice of provolone over pairs of pork pieces and close the grill lid for a minute so the cheese melts. Grill the onions until they’re softened and caramelized on the edges — they add a sweet contrast to the tangy pickles and BBQ sauce.

Assemble and Serve

Build each sandwich by placing the tenderloin pieces on the bottom half of a toasted roll. Top with grilled red onion, a drizzle of your favorite barbecue sauce, and dill pickle chips. Finish with the top half of the roll, slice in half if you like, and serve while warm. These sandwiches pair well with fries, a simple green salad, or coleslaw for a classic summer meal.

Tips and Variations

• If you prefer more flavor depth, add a splash of Worcestershire sauce or a teaspoon of Dijon mustard to the Italian dressing before marinating.
• Swap provolone for Swiss, cheddar, or pepper jack for a different cheese profile.
• For a spicier sandwich, use pickled jalapeños in place of dill pickles or mix a little hot sauce into your BBQ sauce.
• Make ahead: marinate the pork overnight for extra flavor, but remove it from the fridge 20–30 minutes before grilling so it reaches near room temperature for even cooking.
• To keep the meat juicy, avoid overcooking — thin tenderloin steaks cook quickly and are best when just done.

Recipe: Grilled Pork Tenderloin Sandwiches

Ingredients

• 4 pounds pork tenderloin (about 2 tenderloins)
• ¾ cup Italian dressing
• 6 slices provolone cheese
• 1 red onion, thinly sliced
• 6 torta or ciabatta rolls, split
• BBQ sauce, to taste
• Dill pickle chips
• Olive oil, salt, and pepper for grilling onions

Instructions

1. Cut each tenderloin into 2–3 inch pieces. Stand each piece upright with the cut side up and pound to about ½ inch thickness.
2. Arrange the pounded pieces in a glass dish and pour the Italian dressing over them, coating each piece. Cover and refrigerate for 2–3 hours.
3. Preheat the grill to medium-high. Remove the pork from the marinade and let excess drip off. Toss sliced onion with a little olive oil, salt, and pepper.
4. Grill the pork 3–4 minutes per side until cooked through and browned. Grill the onions at the same time, flipping once, until lightly charred and softened.
5. Place provolone over the pork pieces and close the grill briefly to melt the cheese. Remove pork and onions to a platter. Toast split rolls on the grill.
6. Assemble sandwiches: pork on the bottom roll, grilled onion, BBQ sauce, and dill pickles. Top with the other half of the roll, slice, and serve warm.

Notes

These sandwiches are highly adaptable — switch up the cheese, sauce, or pickles to match your taste. They make a great alternative to burgers and are quick to grill once the marinating time is complete.
