Pork Tenderloin Sandwich Louisville KY, Made at Home

A Louisville-style pork tenderloin sandwich pairs a thin, crisp-fried pork cutlet with a soft bun, lettuce, tomato, pickles, and mayonnaise. The familiar Kentucky diner-style version is generous and crunchy, and this home recipe keeps the pork juicy by pounding it evenly and frying it just until safely cooked.

Ingredients

1 pork tenderloin, about 1 lb (450 g), trimmed
1 cup (125 g) all-purpose flour
1 tsp (3 g) garlic powder
1 tsp (3 g) paprika
1 tsp (6 g) fine salt, divided
½ tsp (1 g) black pepper
2 large eggs (about 100 g without shells)
2 tbsp (30 ml) milk
1½ cups (90 g) plain fine breadcrumbs
½ cup (75 g) yellow cornmeal
½ cup (120 ml) neutral frying oil, such as canola, plus more as needed to reach about ½ inch (1.3 cm) in the pan
4 hamburger buns
4 tbsp (60 g) mayonnaise
4 lettuce leaves
1 medium tomato (about 150 g), sliced
8 dill pickle chips (about 30 g)

Instructions

Prepare the pork. Cut the tenderloin crosswise into four equal portions. Place each portion between sheets of parchment or plastic wrap and pound to an even thickness of about ¼ inch (6 mm). Trim or shape the cutlets so each is a little wider than a bun; they will shrink slightly as they cook. Pat dry and season both sides with the remaining ½ teaspoon salt and the pepper.
Set up the breading. In a shallow dish, mix the flour, garlic powder, paprika, and ½ teaspoon salt. In a second dish, beat the eggs with the milk. In a third, combine the breadcrumbs and cornmeal. Coat one cutlet in seasoned flour, shaking off excess, dip it in egg, then press it into the crumb mixture on both sides. Repeat with the remaining cutlets. Set them on a tray for 5 minutes so the coating adheres.
Heat the oil. Pour oil into a large heavy skillet to a depth of about ½ inch (1.3 cm). Heat over medium to medium-high until it reaches about 350°F (175°C), or until a pinch of crumbs sizzles steadily without immediately turning dark. If you have a thermometer, use it to monitor the oil. Avoid crowding the pan, which drops the temperature and can make the coating greasy.
Fry the cutlets. Carefully lower two cutlets into the oil. Fry for about 2–3 minutes per side, turning once, until deep golden and crisp. Time varies with thickness and pan heat, so check the center of each cutlet with a food thermometer: the USDA FSIS safe minimum for whole cuts of pork is 145°F (63°C), followed by a 3-minute rest. Transfer to a wire rack set over a tray, season lightly with a pinch of salt if desired, and rest for 3 minutes. Fry the remaining cutlets, allowing the oil to return to temperature between batches. Do not stack the hot cutlets, which softens the crust.
Assemble the sandwiches. Spread about 1 tablespoon mayonnaise on each bun. Add lettuce, a pork cutlet, tomato slices, and two pickle chips to each. Serve promptly while the coating is crisp.

Tips

Use a meat thermometer rather than relying on color or a fixed frying time. The cutlets are thin, so check from the side into the center; remove them once they reach 145°F (63°C), then give them the required 3-minute rest.
Keep the breading dry and crisp: let excess egg drip off before coating, press crumbs on firmly, and leave space between cutlets in the pan. If the crumbs brown too fast, lower the heat.
For extra crunch, use panko instead of fine breadcrumbs. The crust will be lighter and more jagged; use the same quantity and press it firmly onto the pork.
If the tenderloin is hard to slice, chill it in the freezer for 10–15 minutes first. This firms the meat for easier cutting without freezing it solid.

Serving Suggestions

Serve the sandwiches hot with crinkle-cut fries, potato wedges, coleslaw, or a simple green salad. A side of extra pickles and mayonnaise lets everyone adjust the tang and richness. For a classic diner-style plate, keep the toppings straightforward and let the broad, crunchy cutlet extend beyond the bun.

Variations

For a little heat, add ¼ teaspoon cayenne to the flour or serve with hot sauce. Swap the mayonnaise for mustard or a thin layer of both. You can use panko in place of standard breadcrumbs for a rougher crunch, or leave out the cornmeal and replace it with an equal amount of breadcrumbs for a finer crust. For a lighter, less oily result, cook the breaded cutlets in a single layer in an air fryer according to its manufacturer’s directions, checking with a thermometer for the same safe temperature and rest.

Storage and Reheating

For best texture, store the pork cutlets separately from the buns and fresh toppings. Refrigerate leftovers within 2 hours in a covered container; cooked pork keeps for 3–4 days in the refrigerator. To freeze, wrap cooled cutlets individually and freeze for up to 2 months for best quality. Thaw overnight in the refrigerator. Reheat in a 375°F (190°C) oven or air fryer until crisp and heated through; leftovers should reach 165°F (74°C). Microwaving is safe but tends to soften the breading. Assemble with fresh lettuce, tomato, and pickles just before serving.

Frequently Asked Questions

Is a pork tenderloin sandwich the same as a pork loin sandwich?
A pork tenderloin sandwich is usually made from tenderloin sliced crosswise and pounded thin, then breaded and fried. Some regional or restaurant versions use pork loin instead; it is a different cut but can be prepared in the same general way if pounded evenly.

Can I prepare the cutlets ahead?
You can bread them up to a few hours ahead and refrigerate them uncovered on a rack, which helps the coating stay in place. Fry just before serving for the crispest crust. Do not leave raw, breaded pork at room temperature for more than 2 hours.

Can I bake the breaded pork instead of frying it?
Yes. Arrange the cutlets on a lightly oiled wire rack over a baking sheet, mist or brush the coating with oil, and bake at 425°F (220°C), turning once. Begin checking after about 12 minutes; thickness and ovens vary, so use a thermometer and follow the pork temperature and rest guidance in the instructions.

Why did my breading fall off?
Wet pork, excess flour, or a rushed coating can loosen the crust. Pat the meat dry, shake off extra flour, let the coated cutlets stand for 5 minutes, and turn them gently with tongs rather than repeatedly moving them in the oil.

What oil is best for frying?
Canola, vegetable, or peanut oil works well because each has a neutral flavor and handles frying heat. Avoid butter or extra-virgin olive oil for this shallow-frying method, as they can brown or smoke too quickly.

How do I keep the sandwiches crisp after frying?
Rest the cutlets on a wire rack rather than on paper towels or in a stack, and assemble at the last minute. If you need to hold them briefly, keep them in a single layer in a 200°F (95°C) oven while you fry the remaining batch.
