Family holidays now revolve around my famous prime rib. The rich brown outer layer breaks away to reveal juicy pink meat that gets everyone talking. I've spent many seasons tweaking this dish and found it all comes down to proper method and taking your time for that jaw-dropping table centerpiece.

Why This Method Stands Out

My foolproof approach starts with quick high temperature cooking then switches to slow, gentle heat. I've never seen this technique fail - you'll get that amazing exterior while maintaining perfectly cooked insides. Guests always think I've spent hours mastering complex skills, but it couldn't be more straightforward.

Getting To Know Prime Rib

Prime rib comes from those special ribs numbered 6 to 12. Just picture it as the parent cut that gives us those delicious ribeye steaks. The bones really boost flavor, though you can ask your meat counter to cut and reattach them with string, which makes serving much simpler later on.

Prime Rib Components

  • Prime Rib Roast: For feeding plenty of folks, I grab one weighing 12-16 pounds - truly impressive.
  • Kosher Salt and Black Pepper: Don't hold back here as they build that wonderful crust.
  • Optional Aromatics: Nothing beats the smell of fresh garlic, rosemary and thyme with this meat.
  • Butter: When softened and spread on top, it helps create that lovely dark surface.

Prime Rib Cooking Guide

Step 1 - Get Your Meat Ready
Take the roast out and let it sit for 2 hours, adding salt and pepper immediately after pulling it from the refrigerator.
Step 2 - Start With Heat
Heat your oven to 500°F and cook for 15 minutes to begin forming that delicious outer crust. Make sure you've got good kitchen ventilation.
Step 3 - Lower The Heat
Turn down to 325°F and continue cooking roughly 13 minutes for each pound. Check with a thermometer - 115°F will give rare results while 120-130°F produces medium.
Step 4 - Pause Before Slicing
The toughest part comes now - waiting a full 30 minutes before cutting ensures every bite stays moist and flavorful.

Insider Tricks

Get to know who cuts your meat - they'll steer you toward the best pieces. Don't wait to add seasonings once the meat leaves the fridge, it really changes everything. Never skip that half-hour rest period, and always rely on a quality meat thermometer for perfect results.

Top Sauce Matches

Nothing complements this roast like homemade horseradish cream - its cool zip balances the meat's richness beautifully. You can't go wrong with dripping-based gravy either, or just keep things basic with some au jus to let the beef flavor take center stage.

Storage Smarts

You can keep what's left in your fridge for about 4 days. When it's time to warm things up again, throw in a bit of beef stock and heat slowly in the oven so you don't lose that beautiful pink color we worked so hard to achieve.

Frequently Asked Questions

→ What's the best size roast to pick?
Plan for about a pound per guest. For six to eight folks, grab a roast around seven pounds. Bones add flavor while cooking and can be served too.
→ Why let the meat sit out before cooking?
Starting cooking when the meat’s room temperature helps it heat evenly all the way through. It also allows the seasoning to sink in better.
→ Is that high heat step necessary?
You could skip it, but it creates that tasty crust and holds the juices in. Be ready for a smoky kitchen if you go this route!
→ How long do I rest the roast after cooking?
Leave it for at least half an hour before slicing. Juices redistribute, keeping meat juicy, and it’ll warm up slightly while resting.
→ Could I make the horseradish sauce early?
Yep, mix it up the day before and refrigerate. The flavors meld better this way. Just give it a stir when you’re ready to serve.

Difficulty: Difficult

Cuisine: American

Yield: 8 Servings (8 servings)

Dietary: Low-Carb, Gluten-Free

Ingredients

01 1/4 teaspoon cayenne pepper (optional, for sauce).
02 1/4 cup horseradish, prepared (for sauce).
03 1 cup sour cream (for sauce).
04 1 teaspoon ground black pepper, freshly cracked (for sauce).
05 1/2 teaspoon salt, kosher (for sauce).
06 1 cup heavy cream (for sauce).
07 1 (7-pound) prime rib roast (3 to 4 bones), trimmed from ribs and reattached with twine.
08 1 tablespoon coarse kosher salt.

Instructions

Step 01

Bring the roast to room temperature 2 hours before cooking. Dry it off with paper towels and coat it well with kosher salt, making sure you cover the ribs and all sides. Set it in your roasting pan, fat cap on top.

Step 02

In a medium bowl, mix together sour cream, heavy cream, horseradish, black pepper, cayenne (if using), and salt until smooth. Cover and chill until needed.

Step 03

Set oven rack in the center and warm it up to 500°F.

Step 04

Bake the roast for 15 minutes at 500°F. It might get smoky, so turn on your fans and open a window if needed.

Step 05

Drop the oven's temperature down to 325°F. Roast the meat for 13 minutes per pound (about 1.5 to 2 hours total). Stop once the internal heat hits 115°F for rare or 120-130°F for medium.

Step 06

Take it out of the oven, set it on a cutting board, tent it lightly with foil, and let it sit for half an hour.

Step 07

Cut the meat away from the bones or remove the twine. Slice it into 1/2-inch-thick portions and enjoy with the chilled horseradish sauce.

Notes

  1. It’s easier to cook and slice if your butcher separates and reties the roast for you.
  2. Store leftovers in an air-sealed container in the fridge for up to four days.
