Jake's note

"This recipe uses a reverse-roast (low oven, then high-heat finish) so the center cooks evenly while the herb-butter and RUB PRIME STEAK create an irresistible crust. It’s perfect for holidays—make the compound butter ahead to save time on the day."

Herb Butter Prime Rib Roast with RUB PRIME STEAK

This Herb Butter Prime Rib Roast is built around a simple but transformative idea: concentrate flavor where it matters most by slipping herb-infused butter under the fat cap and finishing the exterior with a high-heat blast. The result is a roast with an evenly cooked, tender pink interior from the low-and-slow phase, and a deeply caramelized, savory crust from the final sear. Fresh rosemary and thyme marry with garlic and RUB PRIME STEAK—its proprietary spice blend—to give a layered savory profile that’s more than the sum of its parts. The compound butter melts into the meat as it roasts, seasoning from the inside out and keeping the interior silky.

This technique is forgiving, which is why it’s ideal for holiday centers or any dinner where you need a reliable showstopper. The bone-in cut adds flavor and helps regulate cooking, while the thermometer-led approach removes guesswork. Make the optional pan sauce from the fond left in the pan to tie the whole plate together. Whether you’re cooking for a crowd or treating the family, the method lets you focus on timing and sides, not frantic last-minute adjustments.

Instructions

Make the compound herb butter and rub

In a bowl, mash the unsalted butter until soft, then stir in chopped rosemary, chopped thyme, minced garlic, RUB PRIME STEAK, kosher salt, and black pepper until evenly combined. Taste and adjust seasoning. Cover and chill for 10 minutes to firm slightly, or leave at cool room temperature if your butter is already soft.

For this step

0.5 cupunsalted butter
2 tbspfresh rosemary, chopped
2 tbspfresh thyme, chopped
6 clovegarlic cloves, minced
2 tbspRUB PRIME STEAK
1 tbspkosher salt
2 tspfreshly ground black pepper

Prepare the roast

Bring the prime rib roast to room temperature for 30–45 minutes (this helps even cooking). Pat dry with paper towels, rub the exterior lightly with olive oil, then loosen the fat cap and spread about two-thirds of the compound butter under the fat and the remaining butter over the top and sides. Tie or truss the roast if needed for even shape.

For this step

4.5 lbprime rib roast (bone-in)
2 tbspolive oil

Low-and-slow roast

Preheat oven to 250°F (120°C). Place roast fat-side up on a wire rack set in a roasting pan and insert a probe thermometer into the thickest part, avoiding bone. Roast until the internal temperature reaches 115–120°F (46–49°C) for medium-rare after searing—about 90–120 minutes for a 4–5 lb roast (times vary—use thermometer).

High-heat finish for crust

Increase oven to 500°F (260°C) (or preheat a hot skillet) and roast or sear the roast 10–15 minutes until the exterior is deeply browned and the thermometer reads 125–130°F (52–54°C) for medium-rare. Remove roast and tent loosely with foil; rest 15–20 minutes (carryover will raise temperature ~5–10°F).

Make quick pan sauce (optional)

While the roast rests, place the roasting pan over medium heat on the stovetop (or use a skillet) and deglaze with beef stock, scraping up browned bits. Reduce by about half to concentrate flavor, then whisk in a spoonful of any reserved compound butter if desired. Season to taste and strain into a gravy boat.

For this step

1 cupbeef stock (for pan sauce, optional)

Carve and serve

Slice the rested roast against the grain into thick slices. Serve with pan sauce on the side and any remaining compound butter. Enjoy immediately—this cut shines with simple sides like roasted potatoes and green vegetables.

Tips from the kitchen

Bring Roast To Room

Letting the roast sit 30–45 minutes shortens cooking time and helps the thermometer read true so the center cooks evenly.

Butter Under The Fat

Loosening the fat cap and tucking the compound butter underneath infuses flavor directly into the meat and prevents the butter from burning on the surface.

Probe Placement Matters

Insert the probe into the thickest part of the meat, avoiding bone and fat to get an accurate internal temperature reading.

Finish With High Heat

A 10–15 minute blast at 500°F or a hot cast-iron sear develops the mahogany crust without overcooking the interior when you’ve hit the low target temp.

Rest Before Carving

Tent loosely with foil and rest 15–20 minutes so carryover finishes cooking and juices redistribute for a juicier slice.

Variations & substitutions

Horseradish Butter Twist

Stir 2–3 tablespoons prepared horseradish into the compound butter for a bright, sharp counterpoint that’s classic with beef.

Smoky Coffee Rub

Swap RUB PRIME STEAK for a coffee-based rub (espresso, smoked paprika, brown sugar) to emphasize earthy, caramel notes on the crust.

Garlic-Free Herb Version

If you prefer a milder profile, omit garlic and boost lemon zest in the butter to brighten flavors without pungency.

Boneless Roast Option

Use a boneless prime rib and reduce initial roasting time slightly; truss tightly so it keeps a uniform shape for even cooking.

Storage & make-ahead

Cool leftovers to room temperature within two hours, then refrigerate in an airtight container for up to 3–4 days. For best texture, slice and store meat separately from pan sauce so you can reheat gently. Reheat slices in a low oven (250°F) with a splash of beef stock covered in foil, or refresh gently in a skillet with a little butter; avoid microwave reheating which dries the meat. You can freeze wrapped slices up to 2 months—thaw overnight in the fridge before reheating.

What to serve with it

Serve thick slices with the pan sauce and any remaining compound butter for melting on top, alongside roasted fingerling potatoes and honey-roasted carrots or a creamy gratin. Bright, slightly bitter greens like sautéed broccolini or cavolo nero cut through the richness. Pair with a full-bodied red wine such as Cabernet Sauvignon or Malbec, and present slices on a warmed platter so the roast stays at serving temperature.

Frequently asked questions

How do I know when the roast is done?

Use the probe thermometer as your guide: remove the roast from the low-temperature phase at 115–120°F for a final medium-rare after searing, then finish to 125–130°F before resting to reach the ideal serving temperature.

Can I skip the high-heat sear?

You can, but you’ll miss the deep, caramelized crust; if you’re worried about oven space, sear in a hot skillet or use the broiler for a few minutes while watching closely.

What size roast works for this timing?

The recipe timing is for a 4–5 lb bone-in roast; larger roasts will take proportionally longer in the low oven—always rely on internal temp rather than clock time.

Can I make the compound butter ahead?

Yes—compound butter can be made up to 3 days ahead and refrigerated or frozen for longer storage; if chilled, let it soften slightly before rubbing under the fat cap.

Should I remove the bones before cooking?

No—cooking bone-in adds flavor and helps regulate temperature; you can request the butcher to French the bones for presentation, but leave them on for roasting.
