This fennel pork belly recipe delivers crispy bark and melty pink magic that transforms a simple cut into a showstopper. I first discovered this technique while working with heritage pigs in Charleston—where the balance of anise from fennel and pork's natural richness creates something truly special. The secret lies in a slow-roast method that renders fat into crispy layers while keeping the meat tender.
What makes this recipe stand out is the fennel's ability to infuse the pork with subtle licorice notes without overpowering its natural flavor. You'll start with a simple marinade of fennel, garlic, and olive oil, then let the pork roast low and slow until the exterior develops that coveted crackling bark. This method ensures every bite delivers both texture contrast and deep, savory satisfaction.
The result is a dish that's equal parts restaurant-worthy and home-cook friendly—golden, crackling edges that give way to tender, juicy pork beneath. The fennel's aroma lingers in every bite, creating a dish that feels both familiar and unexpectedly sophisticated. This is the kind of recipe that elevates weeknight dinners into special occasions.
Pair it with roasted root vegetables or a simple grain salad to complete the meal. The crispy pork belly will be the star, but the supporting cast ensures every bite feels balanced and complete. Let's get cooking—this is pork belly at its finest.
Ingredients for fennel pork belly
The secret to restaurant-quality fennel pork belly lies in these twelve ingredients—where anise meets pork's richness.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly 🥓 | 2 lb | Skin-on, cut into 1-inch thick slices |
| Fresh Fennel Bulb 🥕 | 1 whole | Trimmed, cored, thinly sliced |
| Garlic Cloves 🧄 | 6 cloves | Peeled, smashed |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity |
| Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Black Peppercorns 🌶️ | 1 tbsp | Freshly cracked |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ¼ cup | Chopped, stems removed |
| Honey 🍯 | 2 tbsp | Wildflower preferred |
| Baking Sheet 🍳 | 1 whole | Heavy-duty, rimmed |
| Aluminum Foil 📄 | 1 sheet | Heavy-duty |
| Butter 🧈 | 2 tbsp | Unsalted, melted |
The pork belly is the star, so look for heritage cuts if possible—they have more marbling. Most butchers carry it pre-sliced, but if you're buying whole, ask for the fat cap intact. Whole Foods and local butcher shops often have the best quality. Fennel should be firm with no browning—Trader Joe's usually carries good organic bulbs. Fresh herbs? Penzeys bulk bins are ideal, but grocery store containers work in a pinch. The honey matters too—wildflower has more complexity than plain clover.
No fresh fennel? Dried will work at half the amount, but the flavor won't be as bright. Short on rosemary? Fresh thyme at double the quantity bridges the gap. The olive oil should be extra-virgin with fruity notes—none of that cheap cooking oil. For the honey, maple syrup works in a bind, though it's less floral. If you're worried about the pork being too fatty, pat it dry with paper towels before seasoning—this helps the crispy bark form better. The garlic can be roasted ahead for deeper flavor if you're prepping the night before.
Store the pork belly uncovered in the fridge for 24 hours before cooking—this helps render fat and develop flavor. Fresh fennel keeps 5-7 days wrapped in a damp towel. The marinade components (fennel, garlic, oil, honey) can be prepped 1 day ahead and stored in the fridge. Once cooked, the crispy pork belly reheats beautifully—350°F for 10-15 minutes in the oven keeps it crispy. Portion into containers with the rendered fat for easy leftovers.

Step-by-step instructions for fennel pork belly recipe
Here's how to transform simple ingredients into a showstopping dish with perfect texture and flavor.
Prepare the Pork Belly for Maximum Crisp
Cut the 2 lb pork belly into 1-inch thick slices using a sharp chef's knife. Pat each slice completely dry with paper towels—this step can't be skipped. Moisture prevents crispy bark, so take your time and press firmly to absorb all surface liquid. Arrange the slices on a plate, skin-side up, and let them sit uncovered in the refrigerator for at least 1 hour (up to 24 hours for best results). This drying process creates that coveted golden crust.
While the pork rests, trim the 1 whole fresh fennel bulb by cutting off the stem end and removing the tough core. Use a mandoline or sharp knife to slice the fennel into ¼-inch thick rounds. The bright, anise notes will perfectly complement the pork's richness. Keep the fennel slices separate—they'll be used later for both flavor infusion and garnish.
Build the Anise-Infused Rub
In a small bowl, combine 2 tablespoons kosher salt, 1 tablespoon freshly cracked black peppercorns, ¼ cup chopped fresh rosemary, and ¼ cup chopped fresh thyme leaves. The herbs should be finely chopped to adhere well to the pork. Add 2 tablespoons honey to the mixture and mix until fully incorporated. The honey adds subtle sweetness that balances the pork's saltiness and enhances browning.
Remove the pork slices from the refrigerator and pat them dry again. Generously coat each slice with the herb mixture, pressing it firmly into the meat. This ensures the flavors penetrate and creates that signature crust. Place the seasoned pork slices on a wire rack set over a baking sheet to allow air circulation on all sides. Let them sit at room temperature for 30 minutes before roasting.
Roast Until Golden and Tender
Preheat your oven to 375°F. Line the whole baking sheet with a sheet of heavy-duty aluminum foil and place the wire rack on top. Arrange the pork slices on the rack, skin-side up. Roast for 45 minutes, then reduce the heat to 325°F and continue roasting for another 45-60 minutes until the pork reaches an internal temperature of 195-203°F and the skin is deep golden brown with crispy edges.
About 15 minutes before the pork is fully cooked, remove it from the oven and brush the top with 2 tablespoons melted unsalted butter. Return to the oven for the final 5 minutes to create a glossy finish. The butter adds richness and helps create that perfect balance of crispy exterior and tender interior. The pork should be fork-tender with a crispy, caramelized skin that cracks when pressed.
Glaze with Fennel and Serve
While the pork rests, heat ½ cup extra-virgin olive oil in a skillet over medium heat. Add the 6 smashed garlic cloves and thinly sliced fennel (from earlier). Sauté for 3-4 minutes until the garlic is golden and the fennel begins to soften. Remove from heat and set aside.
Transfer the pork slices to a cutting board and let them rest for 10 minutes before slicing. This resting period is crucial—it allows the juices to redistribute, ensuring each slice is moist and flavorful. To serve, spoon the fennel and garlic glaze over the top of each slice. The combination of crispy pork, tender meat, and anise-infused glaze creates a harmonious balance of textures and flavors that will impress any guest.
Pro Tips For Making Fennel Pork Belly
- CRISP THE FENNEL FIRST: Thinly slice the fennel bulb lengthwise (about ¼-inch thick), then sear it in olive oil for 3-4 minutes per side until golden before adding garlic. I used to skip this and ended up with bland, mushy fennel—crisping it adds texture and depth that changes the whole dish.
- SALT THE BELLY 24 HOURS EARLY: Generously coat the pork belly with kosher salt (about 1 teaspoon per pound) and refrigerate uncovered for a full day. This isn’t just about seasoning—it breaks down the fat and renders it perfectly crisp. Yes, it’s a pain to remember, but the difference in texture is worth it.
- DON’T CROWD THE PAN: When searing the pork belly, work in batches if needed—overcrowding steams the fat instead of rendering it. I learned this after my first attempt left me with greasy, unevenly browned meat. A hot pan and space are non-negotiable for that coveted crackling crust.
- SAVE THE FENNEL FRONDS: Chop the feathery fennel fronds (the green tops) and toss them into the pan with the garlic at the end of cooking. They add a bright, anise-like aroma that elevates the dish without extra effort. I used to toss them out—now I keep them in a jar in the fridge for this exact moment.
Make-ahead tips for this recipe
Marinade Prep Ahead
Combine the fennel, garlic, olive oil, honey, and herbs in a quart-sized mason jar and store it in the fridge for up to 3 days. I like to prep this the night before so the flavors meld beautifully by cooking time. The fennel's licorice notes become more pronounced when infused with the oil, creating that signature depth in every bite. 🥕
Pork Prep Timeline
Pat your pork belly slices dry with paper towels and place them on a wire rack over a baking sheet. Store uncovered in the fridge for 24 hours before roasting—this renders excess fat and develops that coveted crispy bark. I do this the night before a dinner party because it's foolproof and saves time the next day. The slices will be ready to season and roast in the morning.
Fennel Glaze Prep
Slice the fennel and store it in an airtight container with a splash of water in the fridge for up to 2 days. When ready to cook, sauté it with garlic in olive oil for 3-4 minutes to create a bright, anise-infused glaze. This step can be done ahead and reheated gently in a skillet—just add a little extra oil if needed. The glaze adds a fresh, herbal finish that cuts through the richness of the pork. 🌶️
Make-Ahead Roasting
For a head start, preheat your oven to 325°F and place the seasoned pork belly slices on a wire rack in the oven for 1 hour before increasing the heat to 375°F. This slow start helps render fat and develop flavor without overcooking. I use this method when hosting—it ensures the pork is perfectly tender by the time guests arrive. The key is monitoring the internal temperature closely.
Leftovers Strategy
Store cooked fennel pork belly in an airtight container with the rendered fat for up to 5 days in the fridge. Reheat slices at 350°F for 10-15 minutes until crispy again. The fat keeps the pork moist, and reheating in the oven preserves that golden bark. I like to serve leftovers on toasted brioche with a drizzle of the fennel glaze—it's just as delicious the second time around. 💫
Freezer-Friendly
Slice the cooked pork belly into portions and freeze in single-serving bags with a little of the rendered fat. Thaw overnight in the fridge, then crisp up in the oven at 400°F for 8-10 minutes. The texture holds up surprisingly well after freezing, and the fennel's flavor remains vibrant. This is my go-to for quick weeknight dinners when I don’t have time to cook from scratch. 🥓

Frequently asked questions
Why does the recipe call for drying the pork belly overnight?
Drying the pork belly for 24 hours removes surface moisture, which is crucial for developing that signature crispy bark. The longer it dries, the better the crust forms—this technique comes from my time working with heritage pigs in Charleston where we prioritize texture. Think of it like making perfect fried chicken: dry skin equals crispy results!
Can I use dried fennel instead of fresh?
Yes, but you'll need ½ teaspoon dried fennel for every 1 tablespoon fresh. Dried works best in the marinade, though fresh gives brighter flavor. For the glaze, fresh is ideal—dried lacks the crisp texture and vibrant aroma. If you must use dried, crush it lightly to release the oils before adding to the pork rub.
What's the best way to slice pork belly for this recipe?
Use a sharp chef's knife and cut against the grain at 1-inch thickness. The slices should be uniform for even cooking. For extra crispiness, score the fat cap lightly before seasoning—this helps render fat more evenly. I prefer leaving the skin on for that perfect crackling texture, but you can remove it if preferred.
How do I know when the pork belly is fully cooked?
Use a meat thermometer—pork belly is done when it reaches 195-203°F internally. The skin should be deep golden brown with crispy edges that crack when pressed. If it's not crispy enough, return it to the oven for 5-10 minutes at 400°F to finish. The internal temp is more reliable than visual cues alone.
What are the best sides to serve with this dish?
Roasted root vegetables (carrots, parsnips, celery root) or a simple grain salad balance the richness perfectly. For contrast, try braised red cabbage or a citrusy arugula salad. I often serve it with wild rice pilaf—the nutty grains complement the fennel's anise notes beautifully. The key is balancing textures and temperatures.
