How You Should Be Seasoning Beef Tenderloin
Beef tenderloin has long been one of the most sought after cuts of beef thanks to its decadently tender texture (via Tru Organic Beef). It's the reason why tenderloin roasts seem to decorate the tables of every celebration and holiday. It might also be the tenderloin's high price that makes it seem like something worthy of a celebration. Tru Organic Beef points out that tenderloin is often the most expensive cut at the butcher's counter because it only makes up about 1% of a cow's meat. That makes it significantly less common, and the price is adjusted for that scarcity. This is also why filet mignons — which come from the tenderloin – are often the most high-priced menu item at steak houses.
According to The Spruce Eats, the tenderloin's delicate texture is due to where it is located on the cow. The tenderloin is located along the cow's spine, and is a muscle that receives little exercise. Because of this, the meat is much more relaxed and gentle when it's served as a roast. It also means that tenderloins are going to have a lot less fat. Whereas wagyu beef is known for its dense marbling of fat throughout the muscle thanks to the way those cows are raised, the tenderloin has only the slightest coating of fat. The lean nature of the cut also affects its flavor.
Tenderloin needs to be heavily seasoned
Kitchn points out that because beef tenderloin is so lean, it's important for it to be well seasoned. This cut of meat doesn't have an abundance of fat to draw on for flavor, so instead, it's important to season it heavily to keep that expensive roast from coming out bland. Kitchn advises to coat the exterior of the roast with kosher salt to bring out as much of the tenderloin's flavor as possible. It can also help to use dried herbs or potent spices like garlic as well. We recommend using garlic, rosemary leaves, and fresh thyme for a decadent roasted beef tenderloin.
That lack of fat also means that tenderloins can easily dry out when they're cooked. The Spruce Eats recommends utilizing marinades to add more flavor and moisture to the meat or pairing it with a flavorful sauce instead. Tying the tenderloin will also help it cook more evenly and ensure that some sections don't get overcooked.
