Grilled crispy chicharrones take skin-on pork belly through an overnight salt cure, a 3-hour low-and-slow cook at 250°F, and a high-heat finish over direct flame until the skin puffs, blisters, and shatters. You cut 2 lbs of pork belly into 4 square pieces, salt the skin side only overnight, brush off the salt the next day, poke holes through the skin, season the meat side with your favorite BBQ rub, and grill indirect until 185°F internal. Then you crank the heat and crisp the skin side down over direct fire. Chop into bite-sized pieces and serve with fresh guacamole. Serves 4 to 6.

Why the Overnight Salt Cure Creates Crispy Chicharrones

Salt Draws Moisture Out of the Skin

Applying a generous layer of kosher salt to the skin side and leaving it uncovered in the fridge overnight pulls moisture from the skin through osmosis. Dry skin is the most important factor in achieving crispy grilled chicharrones. Wet skin steams instead of crisping, no matter how hot the grill gets. The fridge air accelerates the drying process because refrigerator environments are low-humidity. By morning, the skin should feel noticeably drier and slightly tacky to the touch.

Brush Off the Salt Before Cooking

The salt did its job overnight. Before cooking, brush off all the excess salt from the skin. If you leave it on, the finished chicharrones will be too salty to eat. The salt was a tool for moisture extraction, not seasoning. The meat side gets seasoned separately with your BBQ rub.

Prepping the Pork Belly for the Grill

Score the Meat Side

Use a sharp knife to make shallow crosshatch cuts on the meat side of the pork belly. The scoring allows the BBQ rub seasoning to penetrate deeper into the meat. It also helps the fat render more efficiently during the low-and-slow phase. Cut about 1/4 inch deep. You want to score into the meat, not all the way through to the skin.

Poke Holes in the Skin

This is the step that makes the skin puff during the high-heat finish. Use a skewer, fork, or the tip of a sharp knife to poke dozens of small holes through the skin. The holes need to go through the skin layer only, not into the meat below. These holes allow steam and rendering fat to escape during the high-heat phase. Without them, the steam gets trapped under the skin and creates large uneven bubbles instead of the uniform puffing and blistering that defines great grilled chicharrones.

Season the Meat Side Only

Apply your favorite BBQ rub generously on the scored meat side. Salt, black pepper, garlic powder, onion powder, and paprika work well as a basic blend. Do not season the skin side. The skin will develop its own flavor from the rendering fat and the charring during the high-heat finish. Seasoning on the skin side can also burn and create off-flavors during the crisping phase.

Low and Slow at 250°F for Tender Pork Belly

Indirect Heat, Skin Side Up

Set up the grill for indirect cooking at 250°F. Place the pork belly pieces skin side up on the cooler side of the grill. The low temperature slowly renders the fat layers between the meat and the skin. This rendering is essential for tender, juicy meat and a skin layer that’s primed to crisp. At 250°F, the collagen in the pork belly converts to gelatin over the 3-hour cook, producing that melt-in-your-mouth texture in the meat.

Cook to 185°F Internal

Use an instant-read thermometer to monitor the internal temperature. At 185°F, the connective tissue has broken down sufficiently for tender grilled chicharrones. Some pitmasters push to 195 to 200°F for even more tenderness, but 185°F is the sweet spot where the meat is tender while the structure holds together for the high-heat crisping phase. If you go too high, the pork belly can fall apart when you move it to direct heat.

The High-Heat Finish for Crispy Pork Skin

Crank the Grill and Go Skin Side Down

Remove the pork belly from indirect heat. Open the grill vents or crank the gas burners to get the grill as hot as possible. Place the pork belly pieces skin side down directly over the hottest part of the grill. The high heat hits the skin and causes the fat trapped just below the surface to rapidly turn to steam. That steam escapes through the holes you poked earlier, puffing the skin into blistered, crackling chicharrones.

Watch Closely for Even Crisping

This step happens fast. The skin goes from soft to puffed to crispy to burnt in a matter of minutes. Stay at the grill and watch constantly. Rotate each piece so all areas of the skin get direct contact with the heat. You’re looking for the skin to be uniformly puffed, blistered, and golden with dark spots. When you tap it with tongs, it should sound hollow and feel rigid. Pull immediately when it reaches that point.

Fresh Guacamole for Grilled Chicharrones

Mash, Mix, Serve

Mash 3 ripe avocados in a bowl. Add diced Roma tomato, chopped cilantro, diced white onion, diced jalapeños, lemon juice, and salt. Mix everything together. Taste and adjust the lemon and salt until the balance is right. The guacamole should be bright, slightly tangy, and creamy. The acidity from the lemon and the freshness of the cilantro cut through the richness of the pork belly fat. This contrast is what makes the pairing work.

Step-by-Step: How to Make Grilled Crispy Chicharrones

Step 1: Prep the Day Before

Cut 2 lbs of skin-on pork belly into 4 equal square pieces. Pat completely dry with paper towels. Apply a generous layer of kosher salt on the skin side only. Do not salt the meat side. Place the pieces skin side up on a wire rack over a sheet pan. Leave uncovered in the fridge overnight. The salt pulls moisture from the skin through osmosis, and the fridge air dries the surface further. By morning, the skin should feel dry and slightly tacky.

Step 2: Prep the Next Day

Remove the pork belly from the fridge. Brush off all the salt from the skin. The salt was a drying tool, not seasoning. If you leave it on, the finished chicharrones will be too salty.

Score the meat side in a crosshatch pattern about 1/4 inch deep. This helps the rub penetrate and the fat render during cooking.

Use a skewer or the tip of a knife to poke dozens of small holes through the skin. Go through the skin only, not into the meat. These holes are critical. They allow steam to escape during the high-heat finish, which is what causes the skin to puff and blister into crispy chicharrones. Without the holes, the steam gets trapped and creates large uneven bubbles or prevents the skin from crisping at all.

Season the meat side only with your favorite BBQ rub (or a mix of black pepper, garlic powder, onion powder, and paprika). Leave the skin side unseasoned.

Step 3: Cook Low and Slow at 250°F

Set up the grill for indirect cooking at 250°F. Place the pork belly pieces skin side up on the cooler side. Close the lid. Cook for about 3 hours, or until the internal temperature reaches 185°F. The low temperature renders the fat layers slowly and converts the collagen into gelatin. At 185°F, the meat is tender and the fat between the skin and meat has rendered enough for the skin to crisp properly in the next step.

Step 4: Crisp the Skin Over Direct Heat

Remove the pork belly from indirect heat. Crank the grill to medium-high or high heat. Place the pork belly pieces skin side down directly over the hottest part of the grill. This is the step that transforms the pork belly into chicharrones.

The high heat causes the fat just below the skin to turn to steam. That steam escapes through the holes you poked, puffing the skin into blistered crackling. Stay at the grill and watch constantly. Rotate each piece for even contact with the heat. The skin should puff, blister, turn golden with dark charred spots, and sound hollow when tapped with tongs. This takes only a few minutes. Pull immediately when it reaches that point because it goes from crispy to burnt fast.

Step 5: Make the Guacamole

While the chicharrones rest, mash 3 ripe avocados. Add 1 diced Roma tomato, 2 tablespoons chopped cilantro, 1/4 diced white onion, 2 diced jalapeños, the juice of 1 lemon, and salt to taste. Mix everything together and adjust the lemon and salt until the flavor is bright, tangy, and balanced.

Step 6: Chop and Serve

Chop the grilled chicharrones into bite-sized pieces. Serve hot with the fresh guacamole on the side. The crispy, shattering skin on top with the tender, seasoned pork belly meat underneath and the cool, creamy guacamole for dipping is the combination that makes this dish.
