Crispy chicken sandwiches are super popular right now, but they’re no match for a juicy and flavor-packed breaded pork sandwich!

And this one is huge. The pork chop won’t even fit on the bun… Just the way we like it!

Pork Tenderloin Sandwich

This sandwich recipe got its start in the “Hoosier” state – Indiana – at the restaurant Nick’s Kitchen, in Huntington.

It’s super  popular across the Midwest though, including Iowa, Missouri, and Illinois.

The recipe varies a bit from state to state. Being that Chad is from Iowa, we love the Iowa pork tenderloin sandwich recipe!

It’s a bit different from Indiana’s version – Iowa tenderloin is made with boneless pork loin chops rather than pork tenderloin, so they are a little smaller in size.

When I want to layer on the sauces and toppings, I like to use a pretzel bun. Try it out – I promise you’ll love it! If you are looking for a quick and delicious meal try this air fryer burger recipe.

Ingredient Notes and Substitutions

  • Pork Loin Chops – Go with boneless cuts that are about 1-inch thick – we’ll flatten and tenderize them later.
  • White Pepper I use this when I want a deeper, earthier flavor, and it’s great to use in creamy soups and gravies, where you don’t want to see those little black specks.

    But, if black pepper is all you have, it’ll work just fine.
  • Paprika – Cayenne and chili seasoning are a couple of good substitutes for extra spiciness, if you’re into that.

  • Toppings to Try – Instead of raw red onions, make caramelized onions – they are fabulous!

    Lettuce and tomato, of course, are always good, and I’ve heard native Midwesterners swear by a slice of swiss cheese on top!
  • A Classic Crust – The original Indiana recipe includes crushed oyster crackers for the breadcrumbs.

    I personally don’t think crackers lend as much flavor or hold up for the best crunch, but feel free to try if you want the traditional taste and texture!

    Saltines work, too.
  • Sauces to Slather On! BBQ sauce is always killer. Ranch dressing or a barbecue ranch sauce add a nice cool freshness.

    Or try a sweet honey mustard or a spicy chipotle sauce!

Storing and Reheating Breaded Pork Tenderloin

Cooked pork can be refrigerated for up to 4 days. This is a freezer-friendly pork tenderloin recipe, too!

You can freeze the cooked meat for up to 3 months. If you want to freeze them breaded but uncooked, you can do so for up to 5 months.

I recommend reheating in the oven at around 400°F on a layer of foil. The microwave always works in a pinch, but won’t bring the same crunch back to the crust.

Pork Tenderloin Sandwich FAQ

How do you flatten pork tenderloin? 

You want to butterfly the cut beforehand, getting it nice and even. You’ll then tenderize the pork with a meat mallet, wrapped in plastic wrap to keep things nice and neat, until the meat is ¼“ thick.

Prep Time 10 minutes
Cook Time 12 minutes
Total Time 22 minutes
Course Main
Cuisine American
Method Stovetop
Servings 4


  • 4 boneless pork loin chops, 1-inch thick
  • 1 cup all-purpose flour
  • 2 large eggs
  • 1 teaspoon kosher salt
  • 1/2 teaspoon white pepper
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1/2 teaspoon paprika
  • 1 1/2 cups panko bread crumbs
  • 4 cups vegetable oil

For Serving

  • 4 buns
  • 1 large red onion, peeled and thinly sliced
  • 12 pickle chips
  • condiments of choice, (mayo, mustard, etc.)


  • Butterfly the pork loin chops and place each one between two pieces of plastic wrap. Using a meat mallet, pound each chop to a thickness of ¼-inch.
  • Using 3 rimmed plates or pie plates, set up a breading station. In a small bowl, whisk together the flour and spices, then transfer the mixture to one of the plates. In the second plate, whisk the eggs. Add panko breadcrumbs to the third plate.
  • Dredge one pork chop through the flour, then the egg, and lastly, the panko bread crumbs, being sure to completely coat both sides of the meat at each station.
  • Transfer breaded pork to a baking sheet with a wire rack set over it. Repeat, one at a time, with remaining chops.
  • Add enough oil to the skillet to cover the bottom and come up the sides ½-inch. Place skillet over medium heat and bring to a temperature of 350°F. If you don’t have an instant-read cooking thermometer, you’ll know the oil is hot enough when it starts to shimmer.
  • Using tongs, carefully slide 2 pork chops into the hot oil. Cook on the first side until the bottom is golden brown, about 4 minutes. Use the tongs to flip the breaded pork tenderloin chops over and fry for an additional 2 minutes. Remove chops from the skillet and set on the wire rack to drain off excess oil. Repeat with remaining pork chops.
  • Serve breaded loin chops warm on buns with condiments and toppings of choice. Enjoy!

  1. 5 stars
    These are delicious! I remember back in the day, A@W Rootbeer Restaurant in Illinois had this on the menu. They were wonderful and when I saw this I just had to try and repeat that taste. Great recipe. I highly recommend this recipe to everyone who loves a good sandwich.

  2. I have found that you can cut out one step by drying the sliced and pounded chops and then mix the flour and egg together and finish with the Panko. Works like a charm.
