Ingredients

For the Prime Rib:

For the Garlic Herb Butter Baste:

  • 1 stick unsalted butter
  • 1 tbsp chopped garlic
  • 1 tbsp chopped fresh rosemary
  • 2 tbsp finely diced shallots
  • 1 tsp chopped fresh tarragon
  • ½ tsp cayenne pepper

For the Red Potatoes:

  • 1 lb small red potatoes, halved
  • 2 tbsp olive oil
  • Salt & pepper to taste

Instructions

1. Prep the Prime Rib

Start by trimming any excess fat from the prime rib, leaving about ¼ inch of fat for flavor. Tie the fresh rosemary sprigs to the roast using butcher’s twine to infuse the meat with herbaceous aroma as it cooks.

Generously season all sides of the prime rib with Musket Powder White Label or your preferred seasoning blend. This will help form a flavorful crust as it roasts.

2. Prepare the Rotisserie

Insert your ThermoPro Temp Spike Plus (or another wireless thermometer) into the thickest part of the prime rib to monitor the internal temperature. Secure the roast onto the rotisserie spit and place it over your grill or smoker preheated to 400°F.

3. Cook & Baste the Prime Rib

As the rotisserie turns, baste the prime rib frequently with the garlic herb butter (see recipe below). The continuous basting helps lock in moisture and enhances the flavor.

Cook until the internal temperature reaches 120°F for medium-rare. This will take approximately 1.5 to 2 hours, depending on the size of your roast.

4. Rest & Serve

Remove the prime rib from the rotisserie and let it rest for 10–15 minutes before slicing. This allows the juices to redistribute, ensuring every bite is tender and juicy.

5. Prepare the Garlic Herb Butter

While the prime rib cooks, make the garlic herb butter by combining all ingredients in a small pot. Heat over low heat for 15 minutes, stirring occasionally. The butter should be fragrant and infused with the flavors of garlic, shallots, and herbs.

6. Roast the Red Potatoes

Toss the red potatoes with olive oil, salt, and pepper. Place them in a cast-iron skillet beneath the prime rib on the grill, allowing them to absorb the flavorful drippings as they roast. Cook until fork-tender, about 45 minutes.

7. Slice & Enjoy!

Carve the prime rib into thick slices, drizzle with extra garlic herb butter, and serve alongside the roasted red potatoes for the ultimate feast.

Pro Tips for Perfect Rotisserie Prime Rib

  • Monitor your temperature: A wireless thermometer ensures precise cooking.
  • Let it rest: Resting the meat before slicing helps retain its juiciness.
  • Baste generously: More basting = more flavor and a richer crust.
  • Choose the right seasoning: Musket Powder White Label pairs perfectly with prime rib’s rich, beefy flavor.

This rotisserie prime rib recipe is guaranteed to impress, delivering a tender, juicy, and flavorful roast every time. Pair it with a bold red wine or a classic horseradish sauce for the full steakhouse experience!
