What is the Reverse Sear Method?

This reverse sear method for Prime Rib Roast calls for you to slow roast the salt-aged bone-in rib roast in a hot oven and then finish on high heat to get that golden brown, crispy crust. It’s a perfect method to get medium-rare Prime Rib with little well-done meat. When you refrigerate the Prime Rib roast overnight, the salt works its way into the fat cap and makes the beef mouthwateringly tender.

portioned ingredients for Reverse Sear Prime Rib


  • 10-pound Bone-in Standing Rib Roast: The star of this incredible dish, the prime-grade rib roast, is known for its tenderness and rich flavor. You can use a boneless roast if preferred, although bone-in is preferred for the best flavor. Try a USDA choice cut of ribeye roast if it’s a super special occasion!
  • 2 tablespoons Kosher Salt: Kosher salt has a coarse texture, which helps season the surface of the roast evenly. If unavailable, you can use regular sea salt.
  • ½ cup Unsalted Butter: Butter adds richness and flavor to the roast, while the absence of salt allows you to control the seasoning. If you prefer salted butter, reduce the amount of added salt in the recipe.
  • 3 tablespoons Fresh Rosemary: Rosemary gives a fragrant, earthy flavor that goes really nicely with the richness of the beef. Fresh rosemary is recommended for its vibrant flavor, but you can use dried rosemary if necessary, using about half the amount.
  • 2 tablespoons Fresh Thyme: Thyme provides a subtle, herby aroma and flavor. Fresh thyme works best, but you can substitute it with dried thyme, using half the amount.
  • Coarsely Ground Black Pepper: Black pepper adds a subtle heat and depth of flavor to the roast. Coarsely ground pepper gives a nice texture and visual appeal, but you can use finely ground pepper if preferred.

Kitchen Tools & Equipment

  • Roasting Pan: You’ll need a big pan to cook the prime rib in the oven. Pick one that’s strong enough and fits the size of your roast. You can use a rack inside to lift the meat and help it cook evenly.
  • Meat Thermometer: This tool makes sure your prime rib is cooked just right. Stick it into the thickest part of the meat, away from bones, to check the temperature.
  • Mixing Bowl: You’ll use this bowl to mix the softened butter with herbs and pepper for the rub. Pick a bowl that’s big enough for all the ingredients and easy to mix in.
  • Aluminum Foil: After cooking, cover the roast with foil to let it rest. This keeps the juices inside and makes the meat tender. Just make sure to cover it loosely.
  • Chef’s Knife: A sharp knife is needed for slicing the cooked prime rib. Make sure your knife is sharp for clean slices. Cut against the grain for the best results.

How to Make Reverse Sear Prime Rib

Time needed: 12 hours and 25 minutes.

  1. Season the Roast

  2. Prepare the Roast

    Take the bone-in roast out of the fridge and let it sit at room temperature for about 2 hours. Preheat your oven to 200 degrees.

  4. Apply the Herb Butter

    Spread the herb butter mixture evenly over the entire surface of the raw roast, ensuring it covers well. Place the roast fat side up in a roasting pan or rimmed baking sheet.herb butter rubbed raw roast in baking dish

  5. Cook the Roast

    Bake the roast in the preheated oven until the internal temperature reaches around 115 degrees for medium-rare, which should take about 3 ½ hours. You want it undercooked because it will continue to cook while it rests and later when you blacken the crust.whole cooked rib roast side view

  6. Step 6: Rest the Roast

    Once cooked, remove the roast from the oven and tent the entire roast with aluminum foil. Let the meat rest for about 20 minutes while the oven temp gets raised in step 7.

  7. Brown the Roast

    Increase the oven temperature to 500 degrees. Remove the foil and return the roast to the hot oven. Bake until the exterior is well-browned, about 6 to 10 minutes. Keep an eye on your Prime Rib while it’s in the oven on high heat. You want the outer layer browned, but not blackened.whole cooked rib roast

  8. Slice and Serve

Can This Be Made Ahead?

With a longer cooking time, this recipe is designed to be made ahead! Prepare it the day before and let it marinate in the salt in the fridge overnight. The cooking process is fairly easy. Don’t forget to pull it out of the fridge at least 2 hours before cooking so it can get to room temperature. Start cooking 4-5 hours before being served.

What’s the cooking time for Prime Rib?

– For a medium-rare prime rib roast, target an internal temperature of 115 degrees for medium-rare, which should take about 3-3.5 hours. (Carryover cooking temperature should raise internal temp to about 145 degres while resting)
– For a well-done prime rib roast, achieve an internal temperature of 145-150 degrees with a cook time of roughly 22-25 minutes per pound (roughly 4-4.5 hours).

These times and temperatures are general guidelines; it’s crucial to use a meat thermometer to ensure accuracy and adjust according to your desired level of doneness as the size, cut, oven type, etc. will be different.

How to Store Prime Rib


After the Prime Rib roast is cooked, you don’t want to keep it at room temperature for more than 2 hours. Store Reverse Sear Prime Rib in the refrigerator for up to 4 days in an airtight container.

Reheating Tips

For reheating, you can use a regular oven or an air fryer. Preheat the oven to a low temperature, around 250 degrees, and warm the roast until heated through. Alternatively, in the air fryer, set it to a low temperature, around 250 degrees, and reheat the roast until warmed to your liking.


Cook Prime Rib completely and place in an airtight container. Freeze for up to 3 months. Any longer and you’ll risk freezer burn.

What to Serve with Prime Rib

  • Side Dishes: Mashed Potatoes, Baked Potatoes, Sauteed Green Beans, Creamed Spinach are all classic sides to serve with Prime Rib, especially for Easter or Christmas Dinner!
  • Horseradish: If you like horseradish on your Prime Rib, try my Creamy Horseradish!
  • Au Jus From Drippings: If you want to make an au jus from the drippings, remove some pan juices before raising the oven to high heat. The high heat in the searing process may dry up all the drippings. My Classic Prime Rib post has an easy Au Jus recipe!

Frequent Questions

How do I know when the Prime Rib is ready?

Use a meat thermometer, preferably an instant-read thermometer, to check if your Prime Rib Roast is cooked. Once the internal temperature reaches 145 degrees the rib roast is safe to eat.

Why do you let roast come to room temperature before searing at high heat?

Simply put, you don’t want your Prime Rib to overcook. Allowing it to come to room temperature ensures the internal temperature doesn’t increase while you are reverse searing the crust. This is a good time to remove the pan juices for au jus.

  • Garlic: If you like tons of garlicky flavor in your Prime Rib crust, add 2-3 minced garlic cloves to your herb butter rub. 
  • Seasonings: Use your favorite spice blends or dry grilling rubs instead of the fresh thyme and rosemary. Try a BBQ rub for beef or a black pepper steak seasoning blend.
