This is the one that makes people think you hired a caterer.
Prep time: 20 minutes, plus overnight in the fridge
Cook time: 3.5-5 hours, but always go by temperature, not the clock
Serves: 8-10
Ingredients:
- 6-8 pound bone-in prime rib roast (3-4 ribs)
- 2 sticks butter, softened
- 4-5 cloves garlic, minced
- Fresh and dried basil
- Fresh and dried parsley
- Fresh and dried oregano
- Fresh and dried thyme
- Crushed rosemary
- Salt and pepper

Instructions:
- Mix the softened butter with the minced garlic and all the herbs. Don’t hold back on the aromatics, more is better here.
- Slather the herb butter all over the roast, covering it completely.
- Refrigerate overnight, uncovered or loosely covered, to let the butter and herbs really work into the meat.
- The next day, let the roast sit out to come toward room temperature before it goes in the oven.
- Roast at 225-250°F. This is a low and slow cook, plan for it to take most of the afternoon, roughly 3.5 to 5 hours depending on your exact oven and roast size.
- Use a wireless digital thermometer so you’re not opening the oven constantly to check. Pull the roast once it hits 140°F for medium.
- Let it rest, tented loosely with foil, for at least 20-30 minutes before slicing. This step matters as much as the cook itself, cutting too soon loses all those juices onto the cutting board instead of staying in the meat.
Notes:
The overnight rest with the herb butter on is what separates this from a rushed roast, the flavor has time to actually get into the meat instead of just sitting on the surface. Don’t skip it if you can help it.
A reliable wireless thermometer is worth the investment for a roast this size and this expensive, you don’t want to be guessing on something that feeds the whole holiday table.
Short on time? This one doesn’t really have a shortcut, and that’s okay, it’s meant to be the one dish all year where you take the long way. Save the shortcuts for the sides.
