Irresistible Pork Belly Buns With Spicy Mayo

Few dishes capture the luxurious balance of rich, tender, and fresh flavors like pork belly buns—a modern classic that’s inspired by Taiwanese gua bao and has found global acclaim. This in-depth guide will walk you through making succulent pork belly, fluffy steamed buns, spicy mayo, and all the vibrant toppings that make these handheld treats so addictive. Whether you’re aiming for a weeknight dinner or an impressive party snack, this recipe is tested, detailed, and utterly delicious.

Why These Pork Belly Buns Stand Out

  • Balanced Flavors: Fatty, melt-in-your-mouth pork, sweet and salty glaze, creamy mayo, and fresh, tangy pickles.
  • Restaurant-Worthy Technique: Roasting pork belly with aromatics for maximum tenderness and flavor.
  • Adaptable: Make everything from scratch or use shortcuts for weeknight versions.

Before You Begin: What You’ll Need

Making pork belly buns at home is a multi-part process. Here’s a quick breakdown of the steps:

  1. Prepare and roast the pork belly.
  2. Make the spicy mayo and pickled cucumbers.
  3. Steam or make the buns.
  4. Assemble and serve!

Pro Tip: If you want to save time on a busy night, you can use store-bought steamed buns, but making your own is much more satisfying and yields softer results.

Pork Belly: Marinating And Roasting

Pork belly is the star of this dish. The secret to irresistible buns is pork that’s deeply flavorful, juicy, and tender with caramelized edges. Here’s how to achieve that result every time.

Step 1: Season and Marinate

  • Trim: Remove any stray bones or excess skin from your pork belly slab.
  • Massage: Rub with a mixture of kosher salt and sugar. This both seasons and draws out excess moisture, concentrating flavor.
  • Add Aromatics: Place thickly sliced ginger and scallions underneath and atop the pork in a snug dish.
  • Chill: Marinate uncovered in the fridge for at least 6 hours or overnight for best results.

Step 2: Slow Roast For Tenderness

After marinating, the pork belly is gently roasted to achieve a supremely tender texture with restrained rendering of fat.

  1. Preheat to 300°F (150°C).
  2. Pour enough water or stock to barely cover the bottom of a baking pan.
  3. Lay pork belly atop the aromatics and roast, basting occasionally, until fork-tender—about 2 to 2.5 hours.
  4. To finish, increase the oven to 450°F (230°C) and roast briefly, rendering fat and crisping the edges.

Tip: For ultra-clean slices, cool the pork belly after roasting and chill before slicing and reheating in the buns.

Spicy Mayo: The Creamy, Fiery Spread

No modern pork bun is complete without a spicy, tangy mayo. Here’s a classic combination that balances heat and creaminess:

  • 2/3 cup mayonnaise
  • 2–3 tablespoons sriracha (or to taste)
  • 1 tablespoon freshly squeezed lime juice
  • Pinch of sugar, pinch of salt

Simply whisk together all ingredients until smooth and well-blended. Adjust the heat level to your liking with more or less sriracha.

Quick Pickled Cucumbers

Pickles bring essential freshness and cut through the richness of the pork. These quick pickles are effortless:

  • 1 English cucumber, thinly sliced
  • 2 tablespoons rice vinegar
  • 2 teaspoons sugar
  • 1/2 teaspoon salt

Toss everything in a bowl, massage gently, and let sit for at least 20 minutes, tossing occasionally. The cucumber softens and lightly ferments, bringing crunch and brightness.

Steamed Bao Buns: Pillowy And Tender

The steamed buns are the gentle, slightly sweet vehicles for all that flavor. If possible, make them yourself for unmatched texture and aroma.

Step 1: Prepare The Dough

  • Mix all-purpose flour, sugar, instant yeast, and baking powder in a bowl.
  • Add oil and milk or water, stirring until a sticky dough forms.
  • Knead until smooth, about 10 minutes. Rest until doubled in size, 1–2 hours.

Step 2: Shape And Proof

  • Divide dough into equal balls, then roll into ovals.
  • Brush lightly with oil and fold in half over a greased chopstick or dowel.
  • Place on parchment squares and allow to proof again, 30–45 minutes.

Step 3: Steam

  • Steam buns in batches, ensuring proper spacing, for about 10 minutes until puffed and set.
  • Let cool slightly before peeling apart and filling.

Shortcut: Find frozen gua bao or lotus leaf buns at most Asian supermarkets and steam according to package directions.

Assembly: Building The Perfect Pork Belly Bun

With all components ready, it’s time for the fun part—assembly:

  1. Reheat pork belly slices (if chilled) in a skillet or under a broiler until hot and glazed.
  2. Open each steamed bun and slather the inside with spicy mayo.
  3. Add a generous slice of pork belly, some pickled cucumbers, sliced scallions, and cilantro leaves.
  4. Optional: Sprinkle with crushed roasted peanuts for crunch.

Serve immediately while the buns are fluffy and the pork still warm. Enjoy with extra spicy mayo on the side for dipping!

Make Ahead and Storage Tips

  • Pork Belly: Can be roasted up to 2 days ahead. Chill, slice, and reheat before serving.
  • Spicy Mayo: Lasts up to 1 week in a sealed container in the fridge.
  • Pickles: Best within 2–3 days.
  • Buns: Store steamed buns in an airtight bag, refrigerate up to 3 days, or freeze for longer. Re-steam to serve.

Serving Suggestions

  • Party Platter: Arrange assembled buns on a tray for a make-your-own bao bar. Let guests add their favorite fixings.
  • Meal: Serve 2–3 buns per person for a hearty lunch or dinner, accompanied by a light Asian-style slaw.
  • Pairings: Try with cold Asian beer or unsweetened green tea to balance the richness.

Variations And Add-Ons

There are infinite ways to put your own spin on these buns. Some ideas:

  • Protein: Swap pork belly for crispy tofu, confit duck, or sous-vide chicken for lighter versions.
  • Toppings: Add sliced jalapeños, pickled red onions, or radish for extra spice or crunch.
  • Condiments: Try hoisin sauce or a drizzle of honey-garlic glaze for sweeter notes.

Troubleshooting And Pro Tips

  • Rubbery Pork: If the pork seems tough, it likely needs a longer, slower braise or roast. Check periodically for fork tenderness.
  • Sticking Buns: Steam buns on parchment squares to prevent sticking in the steamer.
  • Making Even Slices: Chill pork belly before slicing for perfect, clean cuts.
  • Flavor Boost: Brush pork belly slices with reduced pan juices or hoisin for extra shine and flavor.
