Pork Belly Recipe Weber: Smoky Grill-Master Results

Achieving perfectly smoked pork belly on a Weber grill requires precision, not luck. This method delivers tender, smoky results every time with a simple dry rub and controlled heat.

I developed this approach after years of trial and error, learning that low and slow is the only way to transform tough pork belly into melt-in-your-mouth perfection. The Weber’s consistent heat distribution makes it ideal for this process.

The secret lies in maintaining 225°F and using fruit wood for subtle sweetness. A final sear creates that coveted crispy exterior while keeping the inside impossibly juicy.

This isn’t just cooking—it’s crafting a dish that will impress even the most discerning barbecue enthusiasts.

Ingredients for Pork Belly Recipe Weber

Simple dry rub, quality pork, and fruit wood—this is grill mastery in ingredient form.

The pork belly needs high quality—look for skin-on with even fat marbling. Most butchers or Costco carry it fresh, but frozen works if thawed properly. 2 lb slabs are ideal for the Weber, giving you enough surface area for that perfect bark. Don’t skip the uniform thickness—trim if needed so it cooks evenly. The fat cap should be at least half the total thickness for best results.

No brown sugar? Raw turbinado sugar adds a nice crunch. Out of paprika? Ancho chile powder brings smokiness. The apple cider vinegar spritz keeps the surface moist—white vinegar works too (just less flavor). For wood, hickory or pecan can sub for fruit wood, but they’re stronger—use sparingly. The mustard binder is optional but helps the rub stick better.

Store uncooked pork belly in the fridge for up to 5 days or freeze for 6 months. Once smoked, it keeps 4-5 days refrigerated. The dry rub can be mixed ahead and stored in an airtight container for 3 months—just shake before using.

Step-by-Step Instructions for Pork Belly on a Weber Grill

Here’s my tested method for achieving competition-level bark and tender meat on your Weber.

Step 1: Score and Season the Pork Belly

Pat the 2 lb Pork Belly completely dry with paper towels. Using a sharp knife, score the skin in a crosshatch pattern, cutting about ⅛-inch deep without piercing through to the meat. This helps the fat render and allows the rub to penetrate deeply.

In a bowl, combine the 0.25 cup Kosher Salt, 2 tbsp Black Pepper, 0.25 cup Brown Sugar, 1 tbsp Paprika, 1 tbsp Garlic Powder, and 1 tbsp Onion Powder. Rub this mixture all over the pork belly, pressing it into the scored skin and meat. For extra adhesion, I first coat the meat with 0.25 cup Yellow Mustard as a binder.

Step 2: Set Up Your Weber for Indirect Smoking

Arrange your charcoal in a two-zone fire on one side of the Weber, leaving the other side empty for indirect heat. Add the 4 pieces Fruit Wood Chunks directly onto the hot coals once they’re covered with white ash. Aim for a consistent temperature of 225-250°F on the indirect side where the pork belly will cook.

Place a disposable aluminum pan filled with water on the indirect heat side to help maintain moisture. This is crucial for preventing the pork belly from drying out during the long cook. Close the lid and adjust the vents to stabilize your temperature before adding the meat.

Step 3: Smoke Until Probe-Tender

Place the pork belly skin-side up on the indirect heat side of the grill. Insert a meat probe into the thickest part of the pork belly, avoiding the fat cap. Smoke undisturbed for 4-5 hours, spritzing occasionally with the 0.25 cup Apple Cider Vinegar to keep the surface moist and build up the bark.

You’ll know it’s ready when the internal temperature reaches 195-203°F and a probe slides in with minimal resistance, like butter. If you didn’t use the 1 tsp Liquid Smoke in your rub, add a few drops to the vinegar spritz for extra smokiness. The skin should be dark mahogany and slightly crispy at this stage.

Step 4: Rest and Finish with Butter

Remove the pork belly from the grill and wrap it tightly in butcher paper or foil. Let it rest for 1 hour in a warm cooler or oven set to 170°F. This resting period allows the juices to redistribute and the collagen to fully break down, resulting in tender, sliceable meat.

Just before serving, unwrap the pork belly and brush the skin with melted 4 tbsp Butter. This adds a glossy finish and extra richness. Slice against the grain into ½-inch thick pieces for serving, ensuring each portion includes some of the crispy skin and tender meat.

Common Mistakes When Making This Dish

Skipping the Score

Cutting that crosshatch pattern into the skin isn’t just for looks—it helps fat render and lets the rub penetrate. I learned this the hard way when my first attempt came out with rubbery skin. Use a sharp knife and go ⅛-inch deep max. 💡

Temperature Swings

Weber grills hold heat well, but don’t peek every 10 minutes—you’ll lose 50°F each time. I use a dual-probe thermometer to monitor grill and meat temps without opening the lid. Stable 225°F is your target.

Rushing the Rest

That 1-hour rest isn’t optional. Slicing too soon sends all those beautiful juices onto your cutting board. I wrap mine in towels inside a cooler—grandmother’s trick that still works perfectly.

Over-Smoking

More wood chunks don’t mean better flavor. With pork belly’s high fat content, 4 apple wood chunks are plenty. Too much smoke creates a bitter taste. I learned this after ruining a batch with 8 chunks.

Skipping the Spritz

That apple cider vinegar spritz every 45-60 minutes keeps the surface moist and builds bark. Skip it, and you’ll end up with dry, tough skin. I use a simple spray bottle from the dollar store.

Wrong Wood Choice

Stick to fruit woods like apple or cherry. Hickory or mesquite can overpower pork belly’s delicate flavor. I made this mistake once—never again. The subtle sweetness of fruit wood complements perfectly. 🌡️
