Porchetta-Style Pork Loin Roast with Crispy Herb Skin and Fennel

Ingredient Spotlight

Fennel seeds

Dried seeds from the fennel plant used across Mediterranean, Middle Eastern and South Asian cuisines; they have a sweet, anise/licorice-like aroma with warm, slightly spicy notes. You’ll find them in the spice aisle or at ethnic markets, sold whole or ground and used in sausages, braises and breads. If you don’t have them, substitute crushed anise seed or a very small pinch of ground star anise; for a fresher, milder hint use chopped fennel fronds plus a touch of sugar when appropriate.

Ingredient Spotlight

Fennel bulbs

The swollen base (bulb) of the fennel plant common in Italian and Mediterranean cooking; it’s crisp and watery raw with a mild anise/licorice note that softens and sweetens when roasted or braised. Fennel bulbs are sold in the produce section and at farmers’ markets and work well sliced for roasting, salads, or braises. If unavailable, use thinly sliced celery or kohlrabi for texture and add a pinch of fennel or anise seed to imitate the flavor.

Jake's note

"This recipe gives you the best of porchetta — crisp, crackling skin and a fragrant herb core — but streamlined for the home oven. It shines for weekend dinners and holiday spreads and scales easily if you want a larger roast."

Porchetta-Style Pork Loin Roast with Crispy Herb Skin and Fennel

Porchetta is all about contrasts: a crackling, savory skin giving way to tender, aromatic pork. This porchetta-style pork loin keeps the spirit of the classic—rosemary, sage, fennel, garlic and bright lemon—while simplifying the execution by using a boneless loin with its skin left on. Tucking a coarse herb and crushed fennel seed paste directly under the skin seasons the meat deeply without the fiddly roll of pork belly, and the scored, dry-brined skin crisps to a satisfying crackle. Roasting the pork on a bed of sliced fennel lets the aromatic vegetable soak up the pan juices and caramelize, creating a built-in, fragrant side that ties the whole plate together.

The recipe is forgiving enough for cooks who want showy results without restaurant-only tricks: a high-heat blast at the start encourages the skin to puff and crisp, then a gentler roast brings the center up to temperature without overcooking. The real payoff is texture—shards of crisp skin, herb-studded slices of meat and silky roasted fennel—making this an ideal centerpiece for a small dinner party, family Sunday supper, or to elevate leftovers for sandwiches and salads.

Instructions

Score and dry-brine the pork

Pat the pork skin thoroughly dry with paper towels. Using a very sharp knife, score the skin in parallel lines about 1/2 inch apart (do not cut into the meat). Rub the skin and scored areas with kosher salt and a little black pepper, then place uncovered on a rack in the fridge for at least 2 hours (or overnight) to dry and concentrate flavor.

For this step

4 lbPork loin with skin (boneless, skin-on)
2 tspKosher salt
1 tspFreshly ground black pepper

Make the herb-fennel paste and season under the skin

In a mortar and pestle or small food processor, combine garlic, rosemary, sage, crushed fennel seeds, lemon zest and olive oil to form a coarse paste. Gently loosen the skin from the meat with your fingers or a small spoon and spread the herb paste directly onto the meat, avoiding the skin; reserve any remaining paste to rub on the exposed meat ends.

For this step

4 clove(s)Garlic cloves, peeled
2 tbspFresh rosemary, finely chopped
1 tbspFresh sage, finely chopped
1 tspFennel seeds, lightly crushed
1 tbspLemon zest (from 1 lemon)
2 tbspExtra-virgin olive oil

Prepare the fennel bed and position the roast

Toss the sliced fennel with a drizzle of olive oil, a pinch of salt and pepper, and spread in an even layer on the bottom of a roasting pan or rimmed baking sheet. Set a rack on top of the fennel and place the seasoned pork loin skin-side up on the rack so juices drip onto the fennel as it roasts.

For this step

2 mediumFennel bulbs, sliced into 1/4-inch wedges (roasting bed)

High-heat blast, then lower and slow roast

Preheat oven to 475°F (245°C). Roast the pork for 25–30 minutes at this high heat to begin crisping the skin. Reduce oven temperature to 325°F (160°C) and continue roasting until an instant-read thermometer inserted into the thickest part of the meat reads 140–145°F (60–63°C), about 55–65 more minutes for a 4 lb roast (adjust time for size). If the skin isn't fully crisp, turn the broiler on for 2–4 minutes watching closely to avoid burning.

Rest the roast

Remove the pork from the oven and transfer to a cutting board. Tent loosely with foil and let rest 15–20 minutes; carryover will raise the internal temperature to the recommended 145–150°F (63–66°C) and juices will redistribute, making slicing easier and juicier.

Slice and serve with roasted fennel

Slice the pork into 1/2-inch thick slices, aiming to showcase the crisp skin and herbly interior. Serve the slices over the roasted fennel and spoon any pan juices over the top. Leftovers are great thinly sliced on sandwiches or tossed into salads.

Tips from the kitchen

Score, but don’t cut

Make shallow, evenly spaced cuts in the skin only; if you slice into the meat you lose the barrier that helps the skin blister and crisp.

Dry brine overnight

Salting and refrigerating the pork uncovered for several hours or overnight concentrates flavor and removes surface moisture, which is essential for crisp skin.

Loosen skin gently

Work slowly with your fingers or the handle of a spoon to lift the skin—ripping it creates uneven pockets and lets the herb paste escape.

Use an instant thermometer

Pull the roast at 140–145°F (60–63°C) and rest; carryover cooking will bring it to the safe, juicy range without drying the loin.

Broil carefully at end

If the skin hasn’t crisped fully, use the broiler for 2–4 minutes while watching constantly and keeping the pan on a middle rack to avoid burning.

Variations & substitutions

Pork shoulder porchetta

Swap in a boneless pork shoulder for more fat and shred-friendly leftovers; extend the low roasting time until the shoulder reaches 190–200°F for pull-apart tenderness.

No-skin herb roast

If you can’t get skin-on loin, spread the herb paste over the exterior and roast at 325°F; finish under the broiler to develop a browned, herb-crusted surface instead of crackling skin.

Citrus-fennel twist

Swap lemon zest for orange zest and add a teaspoon of fennel pollen for a brighter, slightly sweeter aroma that complements roasted fennel beautifully.

Spicy porchetta

Stir 1 teaspoon of red pepper flakes or a tablespoon of harissa into the herb paste for a peppery kick that contrasts nicely with sweet roasted fennel.

Storage & make-ahead

Store sliced leftovers in an airtight container in the refrigerator for up to 3–4 days. To reheat without drying, warm gently in a 300–325°F oven with a splash of stock or reserved pan juices, covered with foil, then finish briefly under the broiler to re-crisp the skin. For sandwiches, serve cold or at room temperature to preserve the texture of the cracked skin.

What to serve with it

Plate slices atop the roasted fennel and spoon any pan juices over the meat; scatter extra chopped rosemary or a drizzle of good olive oil for sheen. Serve with roasted fingerling potatoes or creamy polenta and a bright salad of bitter greens dressed with lemon and olive oil. A medium-bodied Italian red like Chianti or an amber ale pairs well with the herbal, fennel-forward flavors.

Frequently asked questions

Can I use pork tenderloin instead of loin?

Tenderloin is much leaner and smaller, so it cooks faster and won’t have the same fat to keep the meat juicy; if you use it, reduce cooking time and watch internal temperature closely to avoid a dry result.

How long should I dry-brine in the fridge?

At minimum 2 hours will help, but overnight (8–24 hours) is ideal for maximum moisture removal and flavor concentration—just leave it uncovered on a rack.

Why did my skin not crisp?

Common causes are residual surface moisture, scoring too deep, insufficient initial high heat, or crowding the oven; make sure the skin is very dry, salt it well, start hot, and finish under the broiler if needed.

What if the herb paste leaks under the skin?

A small amount won’t hurt the outcome, but to minimize leakage work slowly when loosening the skin and keep the paste relatively drier (less oil) so it adheres better to the meat.

Is it safe to eat pork at these temperatures?

Yes—USDA recommends cooking whole pork to 145°F followed by a rest; removing the roast at 140–145°F and resting achieves a safe, juicy final temperature in the 145–150°F range.

Can I roast the fennel separately?

You can, but roasting it under the rack captures the pork juices and creates a more integrated flavor; if roasted separately, toss with a splash of the pan juices before serving for the same effect.
