Preparation Phase & Tools to Use

To achieve that succulent medium-rare interior with a beautifully caramelized crust, the right tools make all the difference:

• Roasting Pan with Rack: Lifts the prime rib off the bottom of the pan for even air circulation and roasting.
• Meat Thermometer (Instant-Read or Probe): The key to perfect doneness. Medium rare lands around 130°F-135°F internal temp.
• Sharp Chef’s Knife: For clean slicing without tearing the meat.
• Cutting Board with Grooves: Helps collect any juices that escape during carving.
• Aluminum Foil: Used for tenting the roast while it rests, locking in juices.

These tools aren’t fancy but are absolutely essential in turning your roast into a memorable dining experience.

Ingredients for the Easy Medium Rare Oven Roasted Prime Rib

• Prime Rib Roast (Bone-In or Boneless): The star of the dish. Bone-in offers extra flavor and juiciness, but boneless is easier to carve.
• Kosher Salt: Essential for seasoning the meat and drawing out moisture to form a beautiful crust.
• Freshly Ground Black Pepper: Adds a bold bite that complements the richness of the beef.
• Garlic (Fresh Minced or Powder): Brings out deep, savory undertones in the roast.
• Fresh Rosemary & Thyme (or dried): Herbs that lend an aromatic, earthy flavor to the outer crust.
• Olive Oil: Helps the seasonings stick and promotes even browning.

Each ingredient plays a role in enhancing the natural flavor of the meat without overwhelming it. The balance between salt, fat, and herbs gives this prime rib its signature taste.

How To Make the Easy Medium Rare Oven Roasted Prime Rib

Step 1: Prep the Roast

Remove the prime rib from the fridge at least 2 hours before cooking to let it come to room temperature. Pat it dry thoroughly with paper towels.

Step 2: Season Generously

Rub the entire surface of the roast with olive oil. Then, mix salt, pepper, garlic, and chopped herbs and press the mixture evenly all over the roast.

Step 3: Set Up the Oven

Preheat your oven to 450°F (232°C). Place the roast bone-side down (or fat side up if boneless) on a rack in a roasting pan.

Step 4: Sear and Roast

Roast at 450°F for 20 minutes to create a crust. Then reduce the oven temperature to 325°F (163°C) and continue roasting until the internal temperature reaches 130°F for medium-rare (about 15 minutes per pound).

Step 5: Rest and Carve

Remove from oven and tent loosely with foil. Let rest for 20-30 minutes before carving. This locks in the juices and allows the temperature to stabilize for a perfect pink center.

How to Serve and Store Your Prime Rib Roast

Once your prime rib has rested and is perfectly medium rare, slice it against the grain into thick or thin portions depending on preference. Pair it with au jus or horseradish cream for an elevated experience. Classic sides like roasted garlic mashed potatoes, green beans, or Yorkshire pudding make excellent companions.

If you have leftovers, refrigerate them within two hours of serving. Store slices in an airtight container or wrap them tightly in foil. To reheat, gently warm in a low oven or skillet with a splash of broth to retain moisture. Prime rib also makes delicious sandwiches the next day!

Frequently Asked Questions

How much prime rib should I buy per person?

Plan on about 1 pound per person if it includes the bone, or 3/4 pound if boneless. For big eaters or no sides, you might go higher.

Can I prepare this ahead of time?

You can season the roast up to 24 hours in advance and store it in the fridge uncovered. This actually helps dry out the surface, giving you a better crust when roasting.

What if I want it more well done?

For medium, aim for 135°F to 140°F internal temperature. Remember, it will continue to cook slightly as it rests.

Do I need to tie the roast with kitchen twine?

Only if your roast is uneven or boneless. Tying helps maintain shape for even cooking.

Should I use a roasting rack?

Yes! It prevents the bottom from steaming and allows heat to circulate, ensuring that lovely crust all around.

Can I use a different cut?

You can try a ribeye roast, which is similar but usually boneless. The technique will still work with adjustments to timing.
