Indiana Pork Tenderloin Sandwich

Cultural Context

The breaded pork tenderloin sandwich is Indiana's unofficial state sandwich and a cornerstone of Midwest comfort food. Originating in the early 1900s — often credited to Nick Freienstein at Nick's Kitchen in Huntington, Indiana (est. 1908) — the sandwich is defined by its audaciously oversized, hand-pounded cutlet that dwarfs the bun. Every small-town diner and county fair across Indiana serves its own version, and fierce debates rage over who makes the best. The Hoosier tenderloin represents the heartland ethos of generous portions, simple ingredients done right, and unpretentious hospitality.

Ingredients

For the Pork

• 680 g (1½ lb / one whole) pork tenderloin, trimmed of silverskin
• 240 ml (8 fl oz / 1 cup) buttermilk
• 1 large egg
• 5 ml (1 tsp) hot sauce (such as Tabasco)

For the Breading

• 180 g (6¼ oz / 1½ cups) all-purpose flour
• 75 g (2¾ oz / 1 cup) plain breadcrumbs or crushed saltine crackers
• 5 g (1 tsp) garlic powder
• 5 g (1 tsp) onion powder
• 2 g (½ tsp) smoked paprika
• 2 g (½ tsp) freshly ground black pepper
• 5 g (1 tsp) fine sea salt
• 1 g (¼ tsp) cayenne pepper

For Frying

• Vegetable oil or peanut oil, enough for 2.5 cm (1 in) depth in skillet

For Serving

• 4 soft hamburger buns or potato rolls, lightly toasted
• Dill pickle slices
• Yellow mustard
• Sliced white onion
• Iceberg lettuce leaves
• Sliced ripe tomato
• Mayonnaise (optional)

Substitutions:

• Pork tenderloin → boneless pork loin chops, pounded thin (slightly less tender but works well)
• Buttermilk → 240 ml (1 cup) whole milk + 15 ml (1 tbsp) white vinegar, let sit 10 minutes
• Saltine crackers → panko breadcrumbs (crunchier texture, less traditional)

Equipment

• Meat mallet or heavy rolling pin
• Plastic wrap or large zip-top bags
• Three shallow bowls or dishes (for breading station)
• Large heavy-bottomed skillet or cast-iron pan (30 cm / 12 in)
• Instant-read thermometer
• Wire rack set over a sheet pan

Instructions

Preparation (Active time: 15 min)

1. Slice the tenderloin into 4 equal portions: Cut the pork tenderloin crosswise into 4 pieces, each roughly 170 g (6 oz). Place one piece between two sheets of plastic wrap.

2. Pound the cutlets thin: Using the flat side of a meat mallet, pound each piece to about 6 mm (¼ in) thickness. The cutlet should be roughly 18–20 cm (7–8 in) across — significantly larger than the bun. This is the defining characteristic of an Indiana tenderloin. You'll feel the meat spread and thin under each strike.

3. Prepare the buttermilk soak: In a shallow bowl, whisk together the buttermilk, egg, and hot sauce until smooth. Add the pounded cutlets and let them soak while you set up the breading station, at least 5 minutes. The buttermilk tenderizes the pork and helps the coating adhere.

4. Set up the breading station: In one shallow dish, combine the flour, garlic powder, onion powder, smoked paprika, black pepper, salt, and cayenne. In a second dish, spread the breadcrumbs or crushed crackers. Keep the buttermilk bowl as the middle step.

Cooking (Active time: 15 min)

5. Heat the oil: Pour oil into a large cast-iron skillet to a depth of about 2.5 cm (1 in). Heat over medium-high until the oil reaches 175°C (350°F). Test readiness by dropping a pinch of flour into the oil — it should sizzle immediately and float.

6. Bread the cutlets: Working one at a time, lift a cutlet from the buttermilk and let excess drip off. Dredge in the seasoned flour, pressing to coat evenly. Dip back into the buttermilk briefly, then press firmly into the breadcrumbs on both sides. Place on a wire rack. Repeat for all cutlets.

7. Fry the cutlets: Carefully lower 1–2 cutlets into the hot oil (do not crowd the pan). Fry for 3–4 minutes per side, until the coating is deep golden brown and crunchy. Internal temperature should reach 63°C (145°F) for food safety. The breading should be an even, rich golden color with audible crackling when you listen closely.

8. Drain and rest: Transfer fried cutlets to a wire rack set over a sheet pan. Season immediately with a light sprinkle of salt while hot. Let rest for 2 minutes before assembling. Do not place on paper towels — the wire rack keeps the bottom crispy.

Assembly & Finishing

9. Toast the buns: Lightly butter the cut sides of the buns and toast in a dry skillet or under the broiler until golden, about 1 minute.

10. Assemble the sandwiches: Place a lettuce leaf on the bottom bun. Set the fried cutlet on top — it should hang dramatically over the edges of the bun (this is correct and expected). Add pickles, onion slices, tomato, and a generous smear of yellow mustard. Add mayo if desired. Crown with the top bun.

Food Safety & Storage

• Minimum safe internal temperature: 63°C (145°F) for pork, followed by a 3-minute rest
• Storage: Refrigerate leftover fried cutlets (without bun) in an airtight container for up to 3 days
• Freezing: Bread uncooked cutlets, freeze in a single layer on a sheet pan, then transfer to freezer bags. Fry from frozen, adding 1–2 minutes per side. Keeps up to 2 months.
• Reheating: Reheat in a 200°C (400°F) oven on a wire rack for 8–10 minutes to restore crispiness. Avoid the microwave — it makes the breading soggy.

Serving Suggestions

• Serve with classic coleslaw, potato salad, or thick-cut French fries
• Pairs well with a cold domestic lager, cream soda, or sweet iced tea
• Traditional serving style: on a paper-lined plastic basket, diner-style, with a pickle spear on the side

Scaling Notes

Half recipe (½×): Use 2 cutlets. Oil amount stays the same for proper frying depth.

Double recipe (2×): Fry in batches, keeping finished cutlets warm on a wire rack in a 95°C (200°F) oven. Allow oil to return to 175°C (350°F) between batches.

Chef's Notes

• Sourcing: Any pork tenderloin from the butcher or grocery works. Look for pale pink, firm meat with minimal liquid in the package.
• Make-ahead: Pound and brine cutlets in buttermilk up to 24 hours ahead (refrigerated). Bread just before frying for the crispiest result.
• Variations: Some Hoosier cooks use crushed Ritz crackers for a richer, butterier crust. Others add a teaspoon of seasoned salt to the flour for extra punch. A few diners serve theirs on Texas toast instead of a bun.
• Common pitfalls: Don't skip pounding — thick cutlets won't cook evenly and lose the signature overhang. Keep oil temperature steady; too cool and the breading absorbs oil, too hot and it burns before the pork cooks through. Don't press the cutlet with a spatula while frying — let the oil do the work.
