Ingredients for barbecue pork belly slices
Nine ingredients, two pounds of pork belly, and a five-spice rub that delivers restaurant-quality bark every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly 🐷 | 2 lb | Skin-on, sliced into 1-inch thick pieces |
| Five-Spice Powder 🌶️ | 2 tbsp | Store-bought or homemade blend |
| Brown Sugar 🍚 | 1 tbsp | Light or dark variety |
| Smoked Paprika 🌶️ | 1 tbsp | For deep smoky flavor |
| Kosher Salt 🧂 | 1 tbsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Garlic Cloves 🧄 | 4 cloves | Minced for rub |
| Olive Oil 🫒 | 2 tbsp | For basting |
| Apple Cider Vinegar 🍎 | 1 tbsp | For tangy balance |

The pork belly is the star—look for thick-cut slices with good marbling at Whole Foods or your local butcher. Costco often has pre-sliced pork belly that’s perfect for this recipe. If you can’t find it pre-sliced, ask the butcher to cut it into 1-inch thick pieces. The skin should be intact for that crispy bark. For the five-spice powder, Penzeys or any Asian market brand works best—it’s the heart of this recipe’s flavor. If you’re making your own blend, use equal parts cinnamon, clove, star anise, fennel, and Szechuan peppercorn.
No five-spice powder? Mix 1 tsp each of cinnamon, clove, and star anise—it’s not identical, but it’ll get you close. Running out of honey? Maple syrup works too, though it’ll add a slightly different depth. The olive oil can be swapped for avocado oil if you prefer a milder flavor. For the glaze, if you don’t have honey, a mix of brown sugar and water (1:1 ratio) will do in a pinch. The sesame oil is optional but adds a beautiful aroma and sheen—skip it if you’re avoiding nuts or have dietary restrictions.
Store any leftovers in an airtight container in the fridge for up to 5 days. They reheat beautifully in a skillet over medium heat until crispy again. For longer storage, freeze the slices on a tray first to prevent sticking, then transfer to a bag for up to 3 months. I always make extra—these slices reheat so well they’re perfect for quick lunches or last-minute dinner guests. The flavors actually deepen overnight, so don’t hesitate to make a double batch.

Step-by-step instructions for crispy five-spice pork belly slices
Here's how to transform tender pork belly into irresistible slices with crackling bark and melt-in-your-mouth pink centers.
👨🍳 Step 1: Prepare the Five-Spice Rub
In a small bowl, combine the 2 tbsp five-spice powder, 1 tbsp brown sugar, 1 tbsp smoked paprika, 1 tbsp kosher salt, and 0.5 tsp black pepper. Mix well until the spices are evenly distributed and the sugar starts to dissolve slightly into the powder. This aromatic blend is what creates that signature five-spice flavor profile we're after.
Add the 4 minced garlic cloves and 1 tbsp grated fresh ginger to the spice mixture. The garlic and ginger will infuse their bright flavors into the rub, balancing the earthy notes of the five-spice. Give it another quick stir to make sure everything is thoroughly combined. This mixture should be fine enough to cling to the pork belly but not so fine that it becomes a paste.
🍳 Step 2: Coat and Rest the Pork Belly
Pat the 2 lb pork belly slices completely dry with paper towels—this is crucial for developing that crispy bark. The drier the surface, the better the crust will form. Generously coat both sides of each slice with the five-spice rub, pressing it firmly into the meat so it adheres well. I like to do this in batches so I can handle each piece easily without smudging the rub.
Place the rubbed pork belly slices on a wire rack set over a baking sheet. This rack allows air to circulate underneath, which is essential for even browning. Let them rest at room temperature for 30 minutes while you prepare the oven. This resting period helps the rub penetrate the meat slightly and ensures more even cooking.
🔥 Step 3: Roast Until Bark Forms
Preheat your oven to 400°F and position a rack in the middle position. Line another baking sheet with parchment paper for later. Place the pork belly slices on the wire rack and roast for 25-30 minutes, flipping them once halfway through at the 15-minute mark. You'll know they're ready when the edges develop a deep golden-brown crust and the internal temperature reaches 145°F—this is the point where the fat starts rendering but the meat remains tender.
Here's the thing—don't overcrowd the oven. If you're cooking multiple racks, stagger them by 5-10 minutes to maintain even heat. The goal is to get that beautiful bark without steaming the meat. If you notice the bark forming too quickly, tent the pork with foil to slow the browning while it continues cooking through.
🥘 Step 4: Glaze and Finish with Sesame Oil
While the pork belly is still hot, brush each slice with a mixture of 1 tbsp apple cider vinegar, 1 tbsp honey, and 1 tbsp olive oil. This glaze adds a beautiful sheen and balances the rich, spiced flavors with a touch of tangy sweetness. The heat from the pork will cause the glaze to caramelize slightly as you work, creating an even more flavorful crust.
Return the glazed pork belly to the oven for 5-7 minutes to set the glaze. Watch it closely during this time—you want the glaze to bubble and turn slightly glossy but not burn. Once it's ready, remove the slices and drizzle each one with 1 tsp sesame oil. The nutty aroma of the sesame oil complements the five-spice perfectly and adds another layer of flavor. Let the pork belly rest for 5 minutes before serving to allow the juices to redistribute.
🍽️ Step 5: Serve with Confidence
Slice the pork belly into ½-inch thick pieces, cutting against the grain for maximum tenderness. The exterior should be crispy enough to stand up to a fork, while the interior remains juicy and pink—this is the hallmark of perfectly cooked pork belly. Arrange the slices on a platter and garnish with additional sesame oil if desired.
Serve immediately with your favorite sides—steamed greens, pickled vegetables, or a simple cucumber salad all work beautifully. The contrast between the crispy bark and tender meat, combined with the aromatic five-spice rub, makes this dish truly special. And here's a pro tip: save any leftover pork belly in the refrigerator for up to 3 days or freeze it for up to 3 months for future meals.
Pro Tips For Making Barbecue Pork Belly Slices
- CRACK THE FAT FIRST: Pork belly’s fat renders fast—don’t wait for the recipe’s full cooking time to start skimming. After 10 minutes in the pan, use tongs to pull out the rendered fat and discard it (or save it for frying eggs later). This keeps your slices crispy instead of swimming in their own grease.
- SALT THE BELLY 24 HOURS EARLY: I used to think salting pork belly was optional, but the difference is night and day. Generously coat both sides with kosher salt and let it sit uncovered in the fridge overnight. The salt breaks down the proteins, making the meat tender and the crust irresistible—no soggy slices here.
- DON’T RUSH THE REST: After cooking, the belly needs a proper rest—at least 15 minutes under foil—before slicing. I learned this the hard way: cutting too soon turns those perfect slices into a greasy, uneven mess. Let the juices redistribute, and you’ll get clean, crisp edges every time.
- MIX DRY RUB WITH OIL: Skip the dry rub alone—it’ll clump and fall off. Instead, combine your five-spice powder, smoked paprika, and brown sugar with 1 tablespoon of neutral oil (like avocado or grapeseed) to form a paste. Rub this onto the belly, and the spices will stick like glue, giving you that deep, caramelized flavor.
Storing and reheating this barbecue pork belly slices
Refrigerator Storage
Store your crispy pork belly slices in an airtight container with parchment paper between layers to maintain that perfect bark. I swear by glass Pyrex containers because they keep everything fresh and prevent sogginess.
Keep them refrigerated for up to 5 days—the flavors actually deepen as the spices meld further. 💫
Freezer Prep
For longer storage, let the slices cool completely before freezing. Arrange them on a tray lined with parchment paper, then freeze for 1 hour to create individual portions. Transfer to a freezer bag with all air removed—this prevents freezer burn and keeps the bark crispy.
Label with the date and store for up to 3 months.
Oven Reheating
My favorite method is reheating in the oven at 375°F for 10-12 minutes on a wire rack. This restores that beautiful bark without making the meat greasy. Place the slices on the rack to allow air circulation underneath—just like when you first cooked them.
A quick brush with olive oil before reheating helps revive the crispiness. 🔥
Skillet Crisp
For a faster option, heat 2 tbsp neutral oil (like avocado or vegetable) in a skillet over medium-high heat. Add the slices bark-side down and cook for 2-3 minutes until golden brown, then flip briefly. The skillet method works best with smaller batches to avoid steaming the meat.
Microwave Reset
When you're in a hurry, use the microwave on 50% power for 1-2 minutes, covered with a damp paper towel. This keeps the meat warm without drying it out.
For extra crispiness, finish with 30 seconds in the oven or under a broiler—just watch closely to avoid burning the edges.
Leftovers Hack
Save any rendered fat from the original cooking process—it's pure liquid gold! Store it in a small jar in the fridge, then use it later for sautéing vegetables or basting other meats.
I always keep a jar of this pork belly fat on hand for when I'm craving that rich, smoky flavor. 💡

Frequently asked questions
Can I use this recipe with thicker pork belly slices?
For thicker cuts (over 1.5 inches), reduce your oven temperature to 375°F and increase cooking time by 10-15 minutes per side. The key is patience—thicker slices need more time to render fat while developing that perfect crispy bark. Always check internal temp with a meat thermometer, aiming for 145°F.
What's the best way to achieve extra crispy bark?
Start with bone-dry pork belly—pat it thoroughly with paper towels. Use a wire rack over a baking sheet to allow air circulation on all sides. For maximum crispiness, broil the slices for 2-3 minutes at the end of cooking, watching closely to prevent burning. A quick spray with olive oil before the final broil helps too!
Can I substitute the five-spice powder?
For a similar flavor profile, mix 1 tsp each of cinnamon, clove, and star anise with ½ tsp fennel seeds and ½ tsp black pepper. Toast the spices lightly in a dry pan before mixing to deepen their aroma. This blend captures the warm, slightly sweet complexity of traditional five-spice.
How do I prevent the pork belly from becoming too greasy?
Use a wire rack during cooking to allow fat to drip away. Pat slices dry before serving, then blot with paper towels. For extra control, chill the cooked pork belly for 15 minutes before slicing—this firms up the fat slightly. The rendered fat is delicious, so save it in a jar for future cooking!
What are the best sides to serve with these slices?
Try crispy sweet potato wedges tossed in smoked paprika, or a refreshing cucumber salad with rice vinegar and sesame seeds. For a heartier meal, pair with steamed bok choy and jasmine rice. The five-spice flavors work beautifully with Asian-inspired sides like pickled daikon or quick-pickled vegetables.
