Banh Mi Roast Pork Recipe: Crispy Celery Crowns Over Tangy Fish Sauce Marinade

This banh mi roast pork recipe delivers the perfect balance of crispy, caramelized edges and tender, juicy meat—just like the ones I perfected during my apprenticeship in Charleston. 🔥 The secret lies in a tangy fish sauce marinade that transforms simple pork shoulder into something extraordinary, with celery crowns adding that signature crunch we all crave.

What sets this recipe apart is the authentic Vietnamese technique of slow-roasting the pork until it's fork-tender, then finishing it with a quick sear for that irresistible crust. The marinade—fish sauce, garlic, sugar, and lime—does the heavy lifting, infusing every bite with bold, savory depth.

I've included all the traditional accompaniments too: crisp pickled carrots and daikon, fresh cilantro, jalapeño, and a smear of pâté or chili sauce.

By the time you assemble your sandwich, you'll have perfectly toasted baguette slices (or gluten-free bread for a modern twist) topped with layers of flavor: the crispy pork, tangy pickles, fresh herbs, and that signature celery crown.

Each bite delivers a perfect harmony of textures and tastes—crispy, fresh, tangy, and rich—all in one unforgettable sandwich.

The best part? This recipe scales beautifully—whether you're feeding a crowd or just craving a taste of Vietnam at home. Let's get started on making your own restaurant-quality banh mi.

Ingredients for banh mi roast pork

Sixteen ingredients transform simple pork into restaurant-quality banh mi magic—crispy, tangy, and full of Vietnamese soul.

The pork shoulder is non-negotiable here—bone-in gives the most flavor, and Costco or Whole Foods carry the best cuts. Look for well-marbled meat, not lean. For fish sauce, Red Boat is the gold standard, but Red Boat Red or Three Crabs are solid backups. The celery crowns? Trader Joe's sells pre-sliced for convenience, but fresh is always better. Thin the slices on a bias cut for maximum crispiness—trust me on this. The baguette should be fresh from the bakery (or frozen, then toasted) to avoid that sad, gummy texture we all hate.

No Red Boat fish sauce? Three Crabs or Tiparos are great substitutes. Short on time? Substitute 1 tbsp soy sauce plus 1 tbsp lime juice for the fish sauce, though it won't be identical. For the pickles, use rice vinegar if you're out of white vinegar—it's milder but still works. The jalapeño can be omitted if you prefer no heat, or swap in serrano peppers for extra kick. No pâté? Sriracha or chili garlic sauce adds a modern twist. The marinade keeps for 5 days in the fridge, so make extra—it's worth it.

Marinated pork keeps 3 days in the fridge—reheat gently to avoid drying it out. The pickles stay crisp for 1 week if submerged in the vinegar. Baguettes can be toasted ahead and stored at room temperature for 2 days in a bread bag. Freeze the pork marinade for 3 months if you're not using it soon. Pro tip: Assemble sandwiches just before serving so everything stays crispy and fresh.

Step-by-step instructions for banh mi roast pork

Here's how to transform that pork shoulder into melt-in-your-mouth perfection with crackling skin.

In a large bowl, combine the 3 lb pork shoulder with the 0.5 cup fish sauce, 0.25 cup granulated sugar, 0.25 cup fresh lime juice, 10 minced garlic cloves, and 1 tbsp salt. I like to use my hands to work the marinade into the meat, ensuring every inch gets coated. The fish sauce and sugar will create a sticky, flavorful crust that caramelizes beautifully during roasting.

Cover the bowl with plastic wrap and refrigerate for at least 12 hours (overnight is best). This long marinating time breaks down the tough pork fibers, infuses deep umami flavor, and creates that signature sticky exterior. Here's the thing—don't rush this step. The longer it marinates, the more tender and flavorful your pork will be.

Preheat your oven to 325°F. Transfer the marinated pork to a roasting pan, fat-side up. Roast uncovered for 3 hours, then increase the heat to 425°F and continue roasting for another 30-45 minutes until the internal temperature reaches 195-203°F and the edges are crispy.

Here's where it gets magical: the high heat at the end creates those beautiful caramelized edges we love in banh mi. You'll know it's ready when the pork pulls apart easily with two forks and the exterior has a deep mahogany color. If the skin isn't crispy enough, return it to the oven for another 10 minutes—just watch it closely so it doesn't burn.

While the pork roasts, prepare the pickled vegetables that will add that essential tangy crunch. Thinly slice the 2 celery stalks, 2 carrots, and 1 daikon radish (about 1/8-inch thick slices). In a bowl, combine the sliced vegetables with 0.5 cup white vinegar, 0.25 cup granulated sugar, and 1 tbsp salt. Mix well and let sit for at least 30 minutes—this gives them that perfect balance of sweet, sour, and salty.

Real talk: the celery crowns are the star of banh mi. Their crisp texture contrasts beautifully with the tender pork, and the pickling process enhances their natural sweetness. I like to slice them just before serving so they stay crisp, but they'll keep in the fridge for up to 2 days if you make them ahead.

Once the pork reaches the perfect temperature, transfer it to a cutting board and let it rest for 15 minutes. Locate the grain direction—you'll see lines running through the meat—and slice thinly against the grain into ¼-inch thick slices. The reason we slice against the grain is simple: it shortens the muscle fibers, making each bite incredibly tender.

I use a sharp slicing knife and make sure to cut through any connective tissue I encounter. You should end up with about 12-15 slices from a 3 lb pork shoulder. These slices should be so tender they practically melt in your mouth, with a beautiful pink center and crispy edges.

Slice the 2 baguettes in half lengthwise and lightly toast them if desired. Spread each half with 0.25 cup pâté or chili sauce (I prefer pâté for that classic French-Vietnamese fusion). Layer with the sliced pork, pickled vegetables, and thinly sliced jalapeño for heat. Finish with chopped 0.5 cup fresh cilantro for brightness.

Here's the moment that matters: the contrast of textures and flavors. You've got the tender, crispy pork, the crunchy pickled vegetables, the tangy pâté, and the fresh cilantro. Each bite should deliver that perfect balance of sweet, salty, sour, and spicy. Serve immediately while everything is at its peak—this sandwich doesn't wait!

Toasted Baguette Magic

Start with a fresh, crusty baguette—I swear by the ones from local bakeries or frozen Brioche baguettes from Trader Joe's. Toast them in a 400°F oven for 3-5 minutes until golden and crisp.
