Bone-In Vs Boneless Prime Rib: Which One Is Better?

Prime rib is the king of beef cuts! Guaranteed to wow the dinner party when cooked to perfection.

But what is the difference between bone-in and boneless?

How does it affect each stage of the cooking process?

Does it affect things like the cooking time or taste?

Let’s jump in and find out!

Comparing A Prime Rib With Or Without The Bones

Below are the key differences between bone-in roasts and boneless roasts.

I have tried to go through them in chronological order. So you can plan the recipe card towards personal preference…

The fact of the matter is that both are delicious.

A prime rib has an intensely beefy flavor with plenty of marbling. The flavor profile is only truly discovered once the fork has left your lips!

So why not spoil yourself and try both?

Preparation – Bone In Vs Boneless Prime Rib

Take care when preparing this grade of beef. Consider the prep time and plan.

As a rule of thumb, a good boss starts by respecting every stage of the process.

A prime rib has a high level of marbling and a thick fat cap. The main prep for both types will be trimming down the cap to 1/2 an inch.

They both will need a good outside sear using direct and intense heat. This will start the cooking process and help render down some of the fat for the ultimate flavor experience.

Note: You can cut both bone-in and boneless into individual ribeye steaks. But we will be discussing the whole roast in this article.

Bone-In Prime Rib Roasts

A bone-in prime rib will need to be trimmed off the fat cap. It will also likely have more connective tissue around the bones.

Use a sharp knife to carefully remove the outer layer of the fat two 1/2 an inch. The removal of this fat can be harder if you have a bone-in prime rib due to the extra effort needed by navigating between each bone.

Tip: To really wow the dinner party, why not French Trim?

Scrape away the layer of fat and connective tissue away from the bone and towards the meat. This gives a professional and even aesthetic to the dish.

Avoid the bones with direct heat when sealing for a brown crust. This can discolor or burn the beef rib.

Boneless Prime Rib Roasts

Trimming the outer layer of fat on prime beef without the bones is easier. There is a flatter surface and you don’t have to worry about navigating around the bones.

Once trimmed you can then evenly seal each side of the beef. Focusing more so on the side covered with fat.

Note: You can ask your butcher to do the trimming for you! If you’re worried about cutting yourself or don’t have a sharp enough knife.

Let the professionals get to work so you can save time!

The Cooking Method – Bone In Vs Boneless Prime Rib

Both bone-in and boneless cuts should be roasted with medium heat after sealing.

Oh, and don’t forget lots of kosher salt!

Bone-In Prime Rib Roasts

Bone-in meat requires a little extra cooking time.

But more of that later…

This is why I recommend roasting with smoke on an electric pellet grill.

The larger cooking chamber and indirect heat lower the risk of burning the bones. It also lets the connective tissue surrounding them melt into juicy goodness!

But cooking with an oven method will work just as well. Just remember to cover the tip of the bones with aluminum foil.

Boneless Prime Rib Roast

The dense protein and fat marbling in a boneless cut will roast on medium-high heat.

You don’t have to worry about the oven temperature or small space burning the bones! Just transfer the seared meat onto the roasting rack.

Cook at the below temperatures to the preferred level of doneness.

Cooking Temperatures – Bone In Vs Boneless Prime Rib

You don’t want to cook a bone-in or boneless prime rib at a high temperature. Due to the fact the content requires time to render down and become edible.

Bone-In Prime Rib Roasts

Smoke a bone-in Prime rib at an exact temperature of 225°F.

Boneless Prime Rib Roasts

Oven-roast a boneless prime rib at an exact temperature of 250°F.

Cook Times – Bone In Vs Boneless Prime Rib

Cuts of beef can be cooked at different internal temperatures. The degree of doneness is based on personal preference.

Weird – 125°F

Medium – 135°F

Well done – 155°F

Bone-In Prime Rib Roasts

A rare boneless prime rib cooks for 35 minutes per pound at 225°F.

A medium boneless prime rib cooks for 40 minutes per pound at 225°F.

A well-done boneless prime rib cooks for 45 minutes per pound at 225°F.

Boneless Prime Rib Roasts

A rare boneless prime rib cooks for 30 minutes per pound at 250°F.

A medium boneless prime rib cooks for 35 minutes per pound at 250°F.

A well-done boneless prime rib cooks for 40 minutes per pound at 250°F.

Resting – Bone In Vs Boneless Prime Rib

Letting the prime rib rest is a crucial part of the cooking method.

Allowing the proteins to reabsorb moisture lost from evaporation.

When resting the meat will continue to cook. The average is an internal temperature increase of 10°F after 30 minutes of resting.

This should be factored in when monitoring the temperatures.

Bone-In Prime Rib Roasts

The bone will retain heat and can increase the rate of carry overcooking.

Allow the internal temp to raise by 12°F -13°F after 30 minutes of resting. This heat is then retained in the bone so it will not lose temp at a high rate.

Boneless Prime Rib Roasts

A boneless prime rib will lose heat quickly.

Allow the internal temp to raise by around 8°F -9°F after 30 minutes of resting. A boneless piece of meat will then lose temperature at a high rate.

Carving – Bone In Vs Boneless Prime Rib

Bone-In Prime Rib Roasts

Carve against the grain and away towards the bone.

Removing as much meat as you can, before disregarding the rib bones.

Boneless Prime Rib Roasts

Carve against the grain to your desired thickness after resting.

Taste – Bone In Vs Boneless Prime Rib

Both bone-in and boneless prime rib will still taste delicious due to the intense marbling within the meat proteins.

Just make sure you liberally season the meat with salt before rendering the outside fat with a cast Iron Skillet!

Bone-In Prime Rib Roasts

Bones contain marrow, minerals, and fats which will be cooked down into the meat and may give a more intense beefy flavor.

Smoking can also affect the taste because it acts as a seasoning.

Boneless Prime Rib Roasts

A boneless rib roast will still be delicious.

But can lack the intensity of flavor if it still had the bone-in.

Texture – Bone In Vs Boneless Prime Rib

Bone-In Prime Rib Roasts

Beef bone marrow consists of collagen. This type of fat has a high moisture content and will render into the meat.

It is common for bone-in meat to be more juicy and tender due to the residual heat from the bone and extra fat content.

The crispy crust from sealing will not be covering the entire surface area. So parts of the meat won’t have a crispy texture around them.

Boneless Prime Rib Roasts

Cooking a boneless prime rib correctly still gives you tender meat.

But the inner proteins’ moisture will evaporate at a higher rate if not protected by a bone.

But you can be sure of a full surface area crust on a boneless prime rib recipe. Which can also protect the meat drying out from moisture evaporation.

Use A Meat Thermometer To Be Sure Of The Internal Temperatures

Always use a thermometer to accurately monitor the internal temperature.

Insert before cooking into the thickest part of the meat.

Monitor and remove when at required temp.

Make sure the probe is not touching if cooking with the bone-in. This will give a faulty reading.
