Is Prime Rib the Same as Tenderloin Beef?

Is prime rib the same as tenderloin beef – The tenderloin is also referred to as a fillet mignon. A filet is usually a boneless cut of a piece of beef, meat or a fish. It forms an important part of a comfort food dish, because it does not have bones in it. Both kinds of meat cuts/pieces are derived from the meat of the cow/cattle.

People often get confused between a prime rib and a tenderloin. Basically, both prime ribs and tenderloin are varying styles of cuts of meat.

In this article, we’ll show you how prime rib and tenderloin are different.

We shall understand the purpose of both kinds of meat cuts, their prices, the difference based on their respective textures and flavours.

  • Cooking and Purpose

Prime rib is obtained from a bone which is located in a rib roast. So, the prime rib is often also referred to as a rib roast.

On the other hand, the tenderloin is generally sliced as individual steaks. Steaks such as these are commonly referred to as filet mignon.

That’s why tenderloin, too, is often known as fillet mignon. Tenderloin is also often roasted as a whole for cooking purposes.

  • Cost

When one wants to compare these two different cuts of meat based on the aspects of their cost, it is safe to say that tenderloin is probably the costliest cut of meat available in the market.

This is so because the fillet mignon part of an animal is less than the area covered by its ribs, from which the prime rib is cut.

So the scarcity of the tenderloin is higher in proportion to the prime ribs available. This makes it costlier.

Prime rib is not cheap in terms of price either. It is quite expensive because it is cut right from the 6th to the 12th ribs.

This sums up to seven ribs. The cut here is smaller and it also involves less fat.

So, the cutting needs to be more precise. This precision comes from skills, and thus makes the rib roast quite costly.

  • Texture and Flavor

If you are wondering whether prime rib is better than the tenderloin, or the tenderloin is better in taste and texture than the prime rib, then it is quite tricky to answer.

The prime rib is cooked on the bone, and so it contains and retains a very juicy and buttery flavor even after it is cooked.

Filet mignon is a part that is sliced off a cow’s tenderloin, from under its shorter ribs.

This makes the fillet mignon more delicate in texture than the rib roast. So while one is rich in flavor, the other has a wonderful texture.
