Prep Time: 1.5 Hours
Cook Time: 1.5 Hours
Difficulty: Easy


  • 2 tsp fresh thyme finely chopped
  • 2 tsp fresh rosemary
  • 8 medium garlic cloves, finely chopped
  • 4 Tbsp kosher salt
  • 3 Tbsp peppercorn medley (the fresher the better here)
  • 3/4 Cup Dijon mustard
  • 1, 6-bone standing beef rib roast (about 10 to 12 lbs)

Note: As for estimating how big a roast you’ll need, I always say to estimate 2 people for every rib.  While that looks like a lot of meat, all seems to get eaten.


  1. Place the first 3 ingredients in a bowl.  Using the back of a Swiss Diamond Chef’s knife, make a paste by pressing down on the blade of a chef’s knife and dragging the side of it across the garlic at a 15-degree angle. Then salt your garlic and add your herbs, smashing them together until a paste forms. Set aside in a bowl
  2. Crush the peppercorns using either the coarsest setting on a pepper mill or placing the peppercorns in a bag and cracking them with a mallet.   
  3. Combine Peppercorns and mustard with the salt/herb paste in the bowl
  4. Rinse the meat under cold water and pad dry with a paper towel.
  5. Following the line of the bones, cut the meat away in 1 piece leaving just enough to make a hinge.
  6. Rub the meat all over with the mustard/herb mixture. Fit the meat back onto the bones, matching the original position. Tie the meat onto the bones using 1 piece of twine in between each bone.
  7. Place the roast fat-side up on a Swiss Diamond Roasting Pan or in a Swiss Diamond Cast Iron Casserole and allow to sit at room temperature for 1 hour.  Meanwhile, heat the oven to 450°F and arrange a rack in the lower third.
  8. Roast for 45 minutes. Reduce the oven temperature to 350°F and continue to roast until an instant-read thermometer inserted into the center registers 125°F for medium rare, about 1 - 1.5 hrs (depending on the  size of your roast).
  9. Transfer the roast to a cutting board, tent it loosely with aluminum foil, and let it rest for at least 20 to 30 minutes. Remove the twine and bones, slice, and serve.
