How It’s Done

Let It Rest
Pull meat from oven when it’s just under the temp you want. Wrap loosely in foil to rest for half an hour before cutting.
Cook the Roast
Blast at 500°F for 15 minutes. After that, drop down to 325°F and roast till your thermometer says it’s done the way you like.
Prep for Roasting
Crank oven to 500°F. Dry off the roast, slather the whole thing with your herb paste.
Make Herb Rub
Mash up those herbs, garlic, pepper, leftover salt, and oil until it’s a thick spread.
Get Started
Set the roast out to warm up for an hour. Salt it early on and let it sit on the counter.

Choosing the Right Cut

Go for bone-in prime rib—it brings loads of flavor. Ask your butcher if they can slice the bones off and tie them back on; makes slicing a breeze later but you still get all that taste while it roasts. Look for meat with lots of little white fat lines— that’s marbling for juicy results. Try checking Costco, they've got good prices on nice cuts, especially around holidays.

Getting It Cooked Just Right

Follow this super simple method: Start roasting at 500°F for 15 minutes to get a crispy outside, then finish at 325°F. For planning, expect 10-12 minutes per pound if you like it rare, 13-14 for medium-rare, or 14-15 if you want it more done. But don’t just guess—use a meat thermometer! That’s the real trick for nailing the doneness every single time.

That All-Important Rest

Letting it rest isn't optional if you want juicy slices! Once it’s done, cover with foil and give it 30 minutes to hang out. This way, the juices soak right back in instead of spilling out when you slice. Hard to wait, but it’s always worth it. Good chance to finish up your sides or whip up gravy from whatever’s in the pan.

Servin’ It Up

When you’re set to eat, snip off any ties and peel away the bones. Cut across the grain for roughly half-inch thick pieces. Make the slices extra tasty with those pan juices on top. Classic sides like mashed potatoes and bread rolls go great on the table. If you want to go big, bring out some horseradish and pile it all on a big tray. Folks might think they’re out at a steakhouse!

Keeping Leftovers Fresh

Pop any leftover prime rib in the fridge, wrapped up nice and tight, and it’ll keep about four days. Only slice off what you’ll eat each time—the rest stays juicier. To reheat, use a slow 250°F oven till it’s nicely warmed up. Skip the microwave—keeps that perfect pink color. Slices are awesome for next-day sandwiches too!

Frequently Asked Questions

→ When should I prep my prime rib and how do I go about it?

Rub on salt, pepper, and herbs up to a day before and stash it on a rack uncovered in your fridge. Let it sit out for a couple hours before roasting. That way, the flavor soaks in and it cooks nice and evenly.

→ Got leftover prime rib? How can I warm it up and keep it juicy?

Just flash thin slices in a hot skillet for about 20 seconds per side. Or, wrap them in foil with some pan juices and warm in a low oven (250°F) until just heated—aim for 120°F inside.

→ My grocery store only has dried herbs. Any tricks for good taste and the right amount?

Grab about 1 teaspoon dried for every tablespoon of fresh. Toast or crush them to wake up the flavor, and toss in lots of garlic or pepper to boost things up.

→ What should I serve with prime rib to round out the meal?

Whip up mashed potatoes, roast some asparagus, or bake Yorkshire pudding for that classic feel. Toss on some horseradish sauce or au jus too. Want something lighter? Add a simple green salad or some roasted veggies.

Difficulty: Intermediate

Cuisine: American

Yield: 10 Servings (1 rib roast)

Dietary: Low-Carb, Gluten-Free, Dairy-Free

Ingredients

01 5 pounds of prime rib (use double seasoning for larger cuts).
02 Fresh ground black pepper, 2 teaspoons.
03 Sea salt.
04 8 minced garlic cloves.
05 A teaspoon of fresh thyme.
06 2 teaspoons fresh rosemary leaves.
07 1/4 cup olive oil.
08 Optional: Horseradish for the table.

Instructions

Step 01

Pull the meat out an hour ahead of time. Sprinkle salt all over, cover it loosely with some plastic.

Step 02

Set the oven rack in the middle spot and preheat to 500°F (260°C).

Step 03

Stir together oil, garlic, rosemary, thyme, pepper, and 1 1/2 teaspoons of salt in a mixing bowl.

Step 04

Dry the roast with paper towels, then coat it all over with the spice mix.

Step 05

For bone-in, put it in a cast iron pan with the bone side down, or use a rack for a boneless roast.

Step 06

Bake at 500°F for 15 minutes to make a nice crust.

Step 07

Turn oven temp to 325°F (165°C). Cook to your preferred doneness with a thermometer: Rare hits 120°F (49°C) in 10-12 minutes per pound; Medium rare reaches 130°F (54°C) in 13-14 minutes per pound; Medium needs 140°F (60°C) in 14-15 minutes per pound; Medium well gets to 150°F (66°C).

Step 08

Take the roast out 5-10°F before your target temperature. It’ll finish cooking as it rests.

Step 09

Cover loosely with foil and leave it untouched for 30 minutes.

Step 10

Slice it against the grain into 1/2-inch pieces. Serve with horseradish if you’d like.

Notes

  1. If it's bone-in, ask the butcher to cut the bone and tie it back—makes cutting it up later simple.
  2. For boneless, a rack is required—Instant Pot racks can fit well in cast iron.
  3. The meat keeps cooking as it rests, so pull it out a bit early.
  4. Leftovers make awesome sandwiches with horseradish sauce.

Tools You'll Need

  • A cast iron pan.
  • Thermometer for checking meat.
  • Foil for covering.
