This herb-brined pork prime rib roast is an exceptional choice for a celebratory Sunday lunch or a festive dinner party. By brining the pork for five days in a fragrant mixture of thyme, juniper berries, and bay leaves, the meat becomes incredibly succulent and deeply seasoned. The slow-infusion process ensures every slice is tender, while the final roasting at a high temperature creates a beautifully golden, aromatic crust on the outside.
As a dairy-free main course, this roast offers a sophisticated alternative to traditional beef joints without compromising on richness or flavour. Pairing the lean pork loin with the bone-in rib adds a dramatic visual appeal to the table, making it a true showstopper. Serve this centrepiece alongside roasted root vegetables and a crisp seasonal salad for a well-balanced, impressive homemade meal that is sure to delight your guests.

Ingredients for Herb-Brined Pork Prime Rib Roast
5.7L cold water, divided
350ml sugar
150g fine sea salt
8 large fresh thyme sprigs
6 Turkish bay leaves, crumbled
4 juniper berries*
2 teaspoons whole black peppercorns
1 6- to 2.9kg centre-cut pork rib roast (8-bone
about 12 to 14 inches long), well-trimmed
2 tablespoons chopped fresh thyme
2 teaspoons whole black peppercorns, crushed in mortar with pestle or in resealable plastic bag with mallet
How to make Herb-Brined Pork Prime Rib Roast
Combine 0.9L water and all remaining ingredients in medium saucepan. Bring to boil, stirring until sugar and salt dissolve. Pour brine into wide pot or container large enough to hold pork (3- to 4-gallon capacity). Add remaining 4.7L cold water; stir to blend. Let stand until brine is cool to touch, about 1 hour.
Place pork on work surface. Trim off all but 1/4-inch layer of fat from roast. Turn roast over so that rib bones point up. Using boning knife and starting where meat meets rib bones, gradually cut loin away from rack of bones, leaving 2 inches of meat attached to bones (do not cut meat off bones completely). Tie meat back onto bones with kitchen string at 2-inch intervals. Place roast in brine, submerging pork completely and weighing down with heavy pot if necessary. Cover and refrigerate 5 days.
Remove pork from brine; discard brine. Rinse pork under cold running water for 5 minutes to reduce saltiness; pat dry with paper towels. Place pork on rack set over sheet of foil; let stand at room temperature 2 hours.
Position rack in centre of oven and preheat to 204°C. Place pork on rack in large roasting pan. Mix thyme and crushed peppercorns in small bowl; sprinkle mixture over pork. Roast until instant-read thermometer inserted into centre of pork registers 60°C, about 1 hour. Remove from oven. Let roast rest 30 minutes (internal temperature of roast will increase 5 to 10 degrees).
Remove kitchen string from roast. Cut meat into slices and serve.
