This large pork tenderloin sandwich is a hearty, satisfying meal built on juicy, seasoned pork loin, crispy golden breading, and soft rolls. It’s a crowd-pleaser that works for lunch, dinner, or game day, and the method ensures the meat stays tender and flavorful. With a simple buttermilk brine and a quick pan-fry, you get a restaurant-quality sandwich at home.
Ingredients
- 2 lb (900 g) pork tenderloin, trimmed
- 2 cups (480 ml) buttermilk
- 2 tbsp (30 ml) hot sauce (like Frank’s or Tabasco)
- 1 tbsp (15 g) kosher salt, plus more for seasoning
- 1 tsp (2 g) black pepper, plus more for seasoning
- 1 cup (125 g) all-purpose flour
- 1 cup (100 g) panko breadcrumbs
- 1 tsp (2 g) garlic powder
- 1 tsp (2 g) onion powder
- 1/2 tsp (1 g) smoked paprika
- 2 large eggs
- 2 tbsp (30 ml) vegetable oil, for frying
- 6 large sandwich rolls (like hoagie or brioche buns)
- Optional toppings: lettuce, tomato, pickles, mayonnaise, mustard
Instructions
- Slice the pork tenderloin crosswise into 6 equal pieces, about 1 inch (2.5 cm) thick. Place each piece between two sheets of plastic wrap and gently pound with a meat mallet or rolling pin to an even 1/2-inch (1.25 cm) thickness. This ensures even cooking and a tender bite.
- In a large bowl or zip-top bag, combine the buttermilk, hot sauce, 1 tbsp (15 g) salt, and 1 tsp (2 g) pepper. Add the pork pieces, turning to coat. Cover and refrigerate for at least 30 minutes (or up to 4 hours for more flavor). This brine tenderizes and seasons the meat.
- While the pork brines, set up a breading station: in one shallow dish, whisk the eggs with 2 tbsp (30 ml) water. In a second dish, mix the flour, panko, garlic powder, onion powder, and smoked paprika. Season the dry mixture with a pinch of salt and pepper.
- Remove the pork from the buttermilk, letting excess drip off. Dredge each piece in the flour mixture, then dip in the egg wash, then coat again in the flour mixture, pressing gently to adhere. Place breaded pork on a wire rack.
- Heat the vegetable oil in a large skillet over medium-high heat until shimmering (about 350°F / 175°C). Working in batches, fry the pork for 3–4 minutes per side, until golden brown and cooked through. The internal temperature should reach 145°F (63°C) as the safe minimum for whole cuts of pork, per USDA FSIS. Use a food thermometer to check.
- Transfer the cooked pork to a paper-towel-lined plate and let rest for 3 minutes. This rest is essential for juiciness.
- Toast the sandwich rolls if desired. Assemble each sandwich with a piece of pork and your favorite toppings. Serve immediately.
Tips
- Don’t skip the brine: Even 30 minutes makes a noticeable difference in tenderness. If you’re short on time, you can skip it, but the pork will be less juicy.
- Use a thermometer: Pork tenderloin is lean and can dry out quickly. Cook to 145°F (63°C) and no higher; the 3-minute rest brings it to a safe temperature while keeping it moist.
- Keep the oil hot: If the oil cools, the breading absorbs oil and turns greasy. Fry in batches and let the oil return to temperature between batches.
- Substitute buttermilk: If you don’t have buttermilk, mix 1 cup (240 ml) milk with 1 tbsp (15 ml) lemon juice or vinegar and let sit for 5 minutes. It won’t be quite as tangy but works fine.
Serving Suggestions
Serve these sandwiches with crispy french fries, coleslaw, or a simple green salad. For a heartier meal, add a side of baked beans or potato salad. The sandwich also pairs well with pickles and a cold beer (for adults of legal drinking age).
Variations
- Spicy version: Add 1–2 tsp (5–10 g) cayenne pepper to the breading or increase the hot sauce in the brine.
- BBQ style: Brush the cooked pork with barbecue sauce and top with crispy fried onions.
- Baked option: Instead of frying, bake the breaded pork on a wire rack over a baking sheet at 425°F (220°C) for 15–20 minutes, flipping once, until cooked through. Spray with oil for crispness.
- Gluten-free: Use gluten-free flour and breadcrumbs; the rest of the recipe is unchanged.
Storage and Reheating
Refrigerate leftover cooked pork in an airtight container for up to 3–4 days. To reheat, place on a baking sheet in a 350°F (175°C) oven for 8–10 minutes, or until hot and crispy. You can also reheat in an air fryer at 370°F (185°C) for 5–7 minutes. Avoid microwaving, as it makes the breading soggy. If you’ve already assembled the sandwich, store the pork separately from the bread and toppings to keep everything fresh.
Frequently Asked Questions
Can I use pork loin instead of tenderloin? Yes, but pork loin is leaner and can be drier. Slice it thinner and don’t overcook. You may also need to pound it more to get the same thickness.
How do I know when the pork is done? Use an instant-read thermometer inserted into the thickest part of the pork. It should read 145°F (63°C). After resting for 3 minutes, it’s safe to eat.
Can I prepare these ahead of time? You can bread the pork and refrigerate it for up to 4 hours before frying. Fry just before serving for the best texture. Cooked pork can be refrigerated and reheated, but it won’t be as crispy.
What if I don’t have panko? Use regular breadcrumbs or crushed cornflakes for a different crunch. Regular breadcrumbs will be finer and less crispy.
Can I freeze the cooked pork? Yes, freeze cooked, cooled pork in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months. Reheat in the oven or air fryer without thawing.
Why is my breading falling off? Make sure the pork is dry before dredging, and press the breading on firmly. Letting the breaded pork rest for 10–15 minutes before frying also helps the coating adhere.
