In Austin, Texas, our holiday tables demand big, bold flavors, and nothing delivers confidence and spectacle like a properly prepared Porchetta. This isn't just a simple roast; it's the ultimate celebration centerpiece. It's a magnificent spiral of juicy, herb-stuffed pork belly with the most unbelievably crisp, crackling skin you've ever had. This recipe uses a traditional Italian technique combined with a savory collard greens filling and a final, bright Lemony Herb Sauce-it's a labor of love, but the result is a masterpiece that will truly wow your guests.

The most critical step in this entire recipe is removing the skin from the portion of the pork belly that gets rolled to the inside. Any skin left inside the roll will not get crispy; it will turn into a tough, chewy, un-sliceable layer. Removing it is the secret to a tender spiral and a 100% crispy outer crackling.
A Magnificent Holiday Baking Project
This recipe is a study in contrasts. The long, low-and-slow roast tenderizes the meat for hours, melting the fat and rendering it into the savory collard greens filling. The high-heat blast at the end is then used purely to create that signature, shatteringly crisp crust. The final Lemony Herb Sauce, packed with fresh parsley and lemon, provides a crucial, sharp, acidic counterpoint that cuts through the richness of the pork.

How to Make Crispy Porchetta
This is a two-day project. Patience during the rolling and chilling stages is essential for the crackling.
Part 1: Preparing and Stuffing the Pork (Day 1)
- Prep Skin: Place the pork skin side down. Score the meat deeply in a crosshatch pattern (about 1 inch deep). Mark the overlap point. Slice off and discard the skin from the portion that will be rolled to the interior of the spiral.
- Score Outer Skin: Turn the pork skin side up. Carefully score the remaining outer skin in a tight cross-hatch pattern (about ¼ inch deep).
- Cook Filling: Heat 2 Tbsp. olive oil in a large skillet. Add onion and cook until translucent (3 minutes). Add collard greens and fennel seeds; cook until just wilted (2 minutes). Remove from heat and let cool for 10 minutes.
- Fill and Tie: Turn the pork skin side down. Sprinkle the meat evenly with the salt and pepper. Spread the minced garlic, rosemary, lemon zest, black pepper, and the cooled collard greens mixture over the pork. Pat the filling firmly into the meat.
- Roll and Chill: Starting with the shorter, skin-removed side, roll the pork tightly into a spiral. Tie the spiral tightly with kitchen twine at 1-inch intervals. Place in a roasting pan fitted with a rack, uncovered, and chill for 12 hours to dry the skin.
Part 2: Roasting and Crisping (Day 2)
- Slow Roast: Preheat oven to 275°F (135°C). Bake the porchetta until a thermometer registers 160°F (71°C) in the thickest portion of the meat, which takes approximately 4 to 6 hours.
- High-Heat Crisp: Remove the roast and increase the oven temperature to 500°F (260°C).4
- Finish Skin: Return the porchetta to the 500°F oven. Bake until the skin is bubbly, crispy, and deeply browned, about 25 minutes. Baste with the pan drippings during the last 10 minutes of this cook time.
- Rest: Remove from oven, and let rest 30 minutes before slicing.
- Slice: Discard the twine. Slice the porchetta with a serrated knife against the grain.
Part 3: Lemony Herb Sauce
- Make the Sauce: In a medium bowl, stir together the chopped fresh flat-leaf parsley, kosher salt, grated garlic, lemon zest, lemon juice, red wine vinegar, and crushed red pepper.
- Emulsify: Slowly stir in the extra-virgin olive oil until combined. Serve immediately.
Common Mistakes to Avoid
- Skipping the 12-Hour Chill: This is the #1 mistake. If the skin is moist, it will steam instead of crisping. The uncovered chill is non-negotiable for true crackling.
- Slicing Before Resting: If you cut the porchetta immediately, all the delicious internal juices will run out onto the board, leaving the meat dry. The 30-minute rest is essential for a juicy slice.
- Not Removing the Inner Skin: Any skin left inside the roll will turn into a tough, chewy, inedible layer. Remove the skin where the roll overlaps.
Tips and Tricks for Success
- Tie it TIGHT: Use kitchen twine and secure the spiral at 1-inch intervals. This keeps the filling locked inside and helps the roast maintain a perfect, circular shape.
- The Slicing Tool: A serrated bread knife is the absolute best tool for slicing the porchetta, as it can cleanly cut through the hard, crisp crackling without crushing the tender meat inside.
- The Low-Slow-High Method: The 275°F roast tenderizes the meat; the 500°F blast at the end ensures the skin crackles. This two-stage technique is foolproof for a perfect result.
- Baste with Fat: Basting the skin during the final high-heat stage sounds counterintuitive, but you are essentially "frying" the skin in its own hot, rendered fat, making it even crispier.
Variations
- Nutty Filling: Fold 1 cup of toasted pine nuts or finely chopped pistachios into the collard green filling mixture.
- Different Greens: Substitute Lacinato kale or Swiss chard (stems removed) for the collard greens.
- Fig Glaze: Drizzle the roast with a mix of balsamic vinegar and fig jam during the last 10 minutes of the 500°F crisping stage.
How to Serve
This is the ultimate centerpiece for a holiday meal.
- Slice the roast against the grain and arrange it on a platter with the cooked carrots and fresh lemon wedges.
- The Lemony Herb Sauce should be served on the side, as its bright acidity is needed to cut through the rich, savory pork belly.
- Pair with creamy sides like polenta or mashed potatoes.
Make Ahead and Storage
- Make Ahead: The Lemony Herb Sauce can be made up to 2 days in advance. The porchetta must be rolled, tied, and chilled overnight, making it a perfect Day 1 prep item.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheating: The best way to reheat slices and revive the crackling is in an air fryer or a hot, dry skillet for 5-8 minutes.
Recipe Notes / What I Learned
The recipe's instruction to use a low temperature for the initial cook is a lesson in patience. Brisket and pork belly are tough cuts that need low heat to break down the connective tissue and melt the fat. This slow, low cook time (4-6 hours) is what transforms the pork belly from chewy meat into a tender, succulent roast. It's the true secret to the "melt-in-your-mouth" texture.

- 6 Tbsp. lemon juice
- ½ tsp. black pepper
- ¾ cup extra-virgin olive oil
Group: For Serving
- Fresh parsley
- Lemon wedges
Instructions
- Place pork, skin side down, on a work surface. Using a sharp knife, score meat in a crosshatch pattern, about 1 inch deep x 2 inches wide. Starting with one short side, roll pork into a tight spiral; cut a shallow line in skin to mark where it overlaps. Unroll spiral; turn pork skin side up. Using shallow line as a guide, slice to remove skin from portion of pork that will be inside the roll. (Any skin left inside roll will not get crispy.) Carefully score remaining skin in a cross-hatch pattern, about ¼ inch deep x 1 inch wide. Turn pork skin side down; set aside.
- Heat oil in a large skillet over medium-high. Add onion; cook, stirring often, until translucent, about 3 minutes. Add collard greens, fennel seeds, and 1 teaspoon of the salt; cook, stirring often, until just wilted, about 2 minutes. Remove from heat; let cool, uncovered, 10 minutes.
- With skin side down, sprinkle pork belly evenly with parsley, minced garlic, rosemary, lemon zest, black pepper, collard greens mixture, and remaining 4 tablespoons salt; pat mixture into pork.
- Starting with the shorter, skin-removed side, reroll pork belly into a tight spiral (skin-removed side should be on the interior of the spiral). Tie spiral tightly in 1-inch intervals with kitchen twine. Place in a roasting pan fitted with a rack, and chill, uncovered, 12 hours.
- Preheat oven to 275°F. Bake until a thermometer inserted into thickest portion of pork registers 160°F, 4 to 6 hours.
- Remove from oven, and increase oven temperature to 500°F. Bake until skin is crispy and deeply browned, about 25 minutes, basting with drippings during last 10 minutes of cook time. Remove from oven, and let rest 30 minutes.
- Stir together 3 cups chopped fresh flat-leaf parsley, 1 ½ tsp. kosher salt, ¾ tsp. grated garlic, 1 tsp. lemon zest, 6 Tbsp. lemon juice, and ½ tsp. black pepper in a medium bowl. Stir in ¾ cup extra-virgin olive oil until combined. Serve immediately, or store, covered, in refrigerator up to 2 days. Let come to room temperature and stir to recombine before serving.
- Slice porchetta with a serrated knife; discard twine. Serve with Lemony Herb Sauce, fresh parsley, and lemon wedges.

FAQs
Can I use a pork loin or shoulder instead of pork belly?
No. This recipe is specifically for pork belly; its high fat content is essential for both the tenderness of the meat and the crispness of the skin. Loin or shoulder will be dry.
Do I really need to let it chill uncovered for 12 hours?
Yes. This is the most crucial step for crispy skin. The cold, dry air of the refrigerator wicks away all the moisture from the skin, dehydrating it so it can "crack" into perfect, bubbly crackling in the hot oven.5
What if I don't have kitchen twine?
You can use thick, unflavored dental floss, but kitchen twine (usually made of cotton) is highly recommended. You need a strong, sturdy thread to hold the roast in its tight spiral shape during the long cooking process.
