There is something deeply satisfying about a bone-in pork loin roasted the traditional French way — minimal seasoning, a splash of white wine, and the patience to let the oven do its work. The result is tender, juicy pork with a golden crust and a simple pan sauce that tastes far more refined than the effort involved.
This recipe uses the finest cut of the loin near the neck, left on the bone for extra flavour during roasting. A two-hour wine and herb marinade infuses the meat before it even hits the oven, and the liquid in the roasting pan creates a gentle steam that keeps everything moist.
What I love most about this method:
- Hands-off cooking — once it’s in the oven, you’re free for two hours
- Bone-in roasting adds depth of flavour you simply cannot get from a boneless cut
- The pan juices become an instant, elegant sauce with just a splash of broth
If you want a centrepiece roast that looks stunning on the table but requires no culinary gymnastics, this French roast pork loin is exactly what you need.
French Roast Pork Loin — Classic Bone-In Oven Recipe
Ingredients
- 3 pounds pork loin roast bone-in
- 1 ½ teaspoons kosher salt or 1 teaspoon fine sea salt
- 1 teaspoon black pepper freshly ground
- 2 cloves garlic peeled and thinly sliced
- 2 sprigs rosemary
- ¾ cup white wine dry (such as Sauvignon Blanc or Pinot Grigio)
- 1 cup beef broth
- 1 cup water
- 1 sprig parsley for garnish
Instructions
- Calculate total roasting time at approximately 40 minutes per pound (90 minutes per kg). For a 3-pound loin, this is approximately 2 hours. The most reliable method is to use an instant-read thermometer and roast until the internal temperature reaches 145°F / 63°C.
- Pat the pork loin dry with paper towels. Season all surfaces generously with the salt and pepper, pressing the seasoning into the meat with your fingers.
- Peel the garlic cloves, cut into slices and put them between the bones.
- Place the herbs in the bottom of the roasting pan.
- Place the pork loin on top of the herbs, fat side up. Pour the wine and water around (not over) the meat. Cover and refrigerate to marinate for at least 2 hours or overnight.
- When ready to roast, remove the pork from the refrigerator and let it stand at room temperature for 30 minutes. Preheat the oven to 350°F / 180°C (160°C fan-forced).
- Remove the pork from the marinade. Place the rack in the roasting pan, pour the marinade liquid and herbs into the bottom of the pan, and set the pork on the rack, fat side up.
- Roast the meat in the centre of the oven for 2 hours.
- Check for doneness by inserting an instant-read thermometer into the thickest part of the meat, away from the bone. The pork is done when it reaches 145°F / 63°C. Alternatively, pierce with a skewer — the juices should run completely clear with no trace of pink.
- Transfer the pork to a warm serving platter or cutting board. Tent loosely with aluminium foil and rest for 15–20 minutes before carving.
- Place the roasting pan over medium heat on the stovetop (or transfer the drippings to a medium saucepan). Add the beef broth and bring to a simmer, scraping up any browned bits from the bottom of the pan with a wooden spoon. Cook for 2–3 minutes until slightly reduced. Taste and adjust seasoning with salt and pepper.
- Strain the pan sauce through a fine-mesh sieve into a warm sauce bowl or gravy boat, discarding the herb stems.
- Garnish the meat with fresh herbs and serve.

What Makes This French Roast Pork Loin Special
This is not a complicated recipe, and that is precisely the point. Traditional French roasting relies on quality ingredients, proper seasoning, and patience — not elaborate techniques or long ingredient lists.
Three things set this roast apart:
- Bone-in roasting: Leaving the bones attached insulates the meat and conducts heat gently, producing a juicier roast than any boneless loin can deliver.
- The wine and herb marinade: Two hours of contact with white wine, garlic, and rosemary infuses the pork with aromatic flavour before roasting even begins. That same marinade becomes the braising liquid in the pan, generating gentle steam throughout the cook.
- An instant pan sauce: The drippings from the roast combine with beef broth to create a light, savoury jus in under three minutes — no roux, no cream, no fuss.
Equipment You’ll Need
- Large roasting pan with rack: The rack elevates the pork so hot air circulates underneath, giving you even browning on all sides. The pan below catches the drippings and holds the marinade liquid that creates steam.
- Instant-read meat thermometer: The single most important tool for this recipe. Pork loin can go from perfectly juicy to dry and chalky within a few degrees. Targeting 145°F / 63°C removes all guesswork.
- Sharp carving knife: A bone-in loin requires a long, sharp blade to slice cleanly between and along the bones without shredding the meat.
- Aluminium foil: Essential for tenting the roast during its 15–20 minute rest — this step is non-negotiable for juicy slices.
- Medium saucepan: If your roasting pan cannot go on the stovetop, you will need this for making the pan sauce.
A basting brush is a nice addition if you want to baste the pork with pan juices halfway through roasting for extra colour and moisture.
Tips for Best Results
- Bring the pork to room temperature for 30 minutes before roasting. Cold meat straight from the fridge will cook unevenly — the outside dries out before the centre reaches temperature.
- Pat the meat completely dry before seasoning. Surface moisture creates steam at the beginning of roasting, which prevents browning.
- Do not skip the resting time. Cutting into the roast immediately releases all the juices onto your cutting board instead of keeping them in the meat. Fifteen minutes of resting makes an enormous difference.
- Slice against the grain for the most tender eating experience. On a bone-in loin, slice between the ribs first, then cut the boneless portions across the grain of the muscle fibres.
- Use the 40-minute-per-pound rule as a guide, not gospel. Oven temperatures vary, and the shape of your specific roast affects cooking time. The thermometer is your true indicator of doneness.
Substitutions and Variations
- Wine: Dry vermouth is an excellent substitute and keeps longer in the pantry. For a non-alcoholic version, use unsweetened apple juice with 1 tablespoon of white wine vinegar to mimic the acidity.
- Broth: Chicken broth produces a lighter, more delicate sauce. Vegetable broth works but lacks the body of beef or chicken.
- Herbs: Thyme or sage can replace rosemary. A bay leaf added to the marinade liquid adds subtle depth.
- Garlic: For a more intense garlic flavour, make small slits in the flesh of the pork and push garlic slivers directly into the meat rather than only placing them between the bones.
- Boneless loin: You can use a boneless pork loin roast. Reduce the cooking time to approximately 30 minutes per pound and check the temperature earlier — boneless cuts cook faster and dry out more easily.
Storage and Reheating
- Refrigerator: Store sliced or whole leftover pork in an airtight container for up to 3 days. Pour any remaining pan sauce over the meat before sealing to keep it moist.
- Freezer: Wrap individual portions tightly in cling film, then aluminium foil, and place in a freezer bag. Freeze for up to 3 months. Thaw overnight in the refrigerator.
- Reheating: Place sliced pork in an oven-safe dish, spoon pan sauce or a splash of broth over the top, cover with foil, and warm at 300°F / 150°C for 15–20 minutes. Avoid the microwave if possible — it tends to make pork loin rubbery.
What to Serve With This
French roast pork loin pairs beautifully with sides that can absorb the light pan sauce:
- Gratin dauphinois (scalloped potatoes) — the classic French accompaniment to roast pork
- Roasted root vegetables — carrots, parsnips, and turnips roasted alongside the pork in the last 45 minutes
- French green beans (haricots verts) blanched and tossed with butter and flaked almonds
- Mashed potatoes enriched with butter and a splash of the pan sauce
- A crisp green salad dressed with Dijon vinaigrette to cut through the richness of the meat
- Crusty French bread for mopping up every last drop of the jus
Frequently Asked Questions
What internal temperature should pork loin reach?
The USDA recommends cooking pork to an internal temperature of 145°F / 63°C followed by a 3-minute rest. At this temperature the meat will be slightly pink in the centre, which is perfectly safe and much juicier than the old recommendation of 160°F. Use an instant-read thermometer inserted into the thickest part of the loin, away from the bone.
Why is the oven temperature set to 350°F instead of higher?
Pork loin is a lean cut that dries out quickly at high temperatures. Roasting at 350°F / 180°C allows the meat to cook gently and evenly, with the steam from the wine and water in the pan keeping the environment moist. This lower temperature also gives you a wider margin of error before the meat overcooks.
Can I marinate the pork overnight instead of two hours?
Yes, and the flavour will be noticeably better. Cover the roasting pan tightly with cling film and refrigerate for up to 12 hours. The wine’s acidity gently tenderises the surface of the meat while the garlic and rosemary aromatics penetrate deeper. Just remember to bring the pork to room temperature for 30 minutes before roasting.
How do I know when the pork is done if I do not have a thermometer?
Pierce the thickest part of the meat with a metal skewer or thin knife and hold it there for 5 seconds. Remove it and immediately touch the skewer to the inside of your wrist. If it feels hot (not warm), the pork is done. Additionally, the juices that run out should be completely clear with no pink tinge. However, a thermometer is strongly recommended for consistent results.
Why do the bones stay in for this recipe?
Bones conduct heat slowly and act as a natural insulator for the meat closest to them. This means the pork cooks more gently near the bone, staying juicier. The bones also add flavour to the pan juices as the marrow and connective tissue render during roasting. Once the pork is cooked, the meat near the bone is often the most succulent part of the entire roast.
Can I use this method for a larger pork loin?
Absolutely. Scale the marinade ingredients proportionally and adjust the roasting time using the 40-minutes-per-pound guideline. A 5-pound roast will need approximately 3 hours and 20 minutes, but always verify with your thermometer. You may also need to add more liquid to the roasting pan halfway through to prevent it from drying out and burning.
The French Tradition of Rôti de Porc
Rôti de porc — French roast pork — is one of the cornerstones of cuisine bourgeoise, the everyday home cooking of France. Unlike the elaborate dishes of haute cuisine, this style of cooking celebrates simplicity: a fine piece of meat, basic aromatics, and careful attention to technique. The tradition of roasting pork on the bone with white wine dates back centuries in French farmhouse kitchens, where the wine served a practical purpose — it tenderised tougher cuts and provided liquid for basting in wood-fired ovens with unpredictable heat.
The cut near the neck, specified in this recipe, is prized in French butchery for its balance of lean meat and just enough intramuscular fat to stay moist during long roasting. In France, your butcher would prepare this cut specifically tied and trimmed for roasting — a service that reflects the deep cultural importance of a proper Sunday rôti.
