Costco’s beef tenderloin. Just the name evokes images of elegant dinners, juicy steaks, and melt-in-your-mouth tenderness. Buying a whole tenderloin at Costco is a fantastic way to save money on this premium cut of meat, but it can also be a little intimidating if you’re not sure what to do with all that beef! Fear not, aspiring home cooks! This comprehensive guide will walk you through everything you need to know about preparing and cooking Costco beef tenderloin, with a plethora of delicious recipe ideas to impress your family and friends.
Understanding the Marvel of Beef Tenderloin
Beef tenderloin, also known as filet mignon, is arguably the most tender cut of beef. It comes from the loin, which runs along the spine of the animal. Because this muscle isn’t heavily used, it remains incredibly soft and yields a buttery texture when cooked properly. The tenderness is the key appeal of beef tenderloin.
The Costco beef tenderloin typically comes as a whole, trimmed or untrimmed, piece of meat. An untrimmed tenderloin, also called a PSMO (Peeled Side Muscle On), will require some trimming to remove the silver skin and excess fat. While it might seem daunting, trimming your own tenderloin can save you even more money. A trimmed tenderloin, on the other hand, is ready to cook right out of the package.
The Cost-Effectiveness of Buying in Bulk
Purchasing a whole beef tenderloin from Costco is often significantly cheaper per pound compared to buying individual steaks or smaller portions from your local butcher. Buying in bulk allows you to control the portion sizes and customize your meals. You can cut steaks to your desired thickness, roast the entire tenderloin for a special occasion, or even grind some of it for gourmet burgers.
Preparing Your Costco Beef Tenderloin
Proper preparation is crucial to achieving the best results with your beef tenderloin. Whether you bought a trimmed or untrimmed tenderloin, a few key steps will ensure a flavorful and perfectly cooked meal.
Trimming the Tenderloin (If Necessary)
If you purchased an untrimmed tenderloin, the first step is to remove the silver skin. This thin, membrane-like layer is tough and doesn’t break down during cooking, which can make the meat unpleasant to eat. To remove the silver skin, slide a sharp knife (a boning knife works best) under the edge of the silver skin and angle the blade slightly upwards. Gently pull the silver skin taut while running the knife along it, removing it in strips. Take your time and be careful not to remove too much meat along with the silver skin.
Next, trim away any excess fat from the tenderloin. While a little fat is desirable for flavor, too much can cause flare-ups during cooking. Trim the fat cap to about 1/4 inch thickness. You can also remove the chain, a smaller strip of muscle that runs along the side of the tenderloin. This chain can be used for stews or ground beef.
Tying the Tenderloin
Tying the tenderloin with butcher’s twine helps to create a uniform shape, ensuring even cooking. Tying helps the tenderloin cook evenly and maintain its cylindrical shape. Use kitchen twine to tie the tenderloin at approximately 1-inch intervals. This will prevent the thinner tail end from overcooking while the thicker center reaches the desired temperature.
Seasoning for Success
Seasoning is essential to enhance the natural flavor of beef tenderloin. A simple combination of salt and freshly ground black pepper is often all you need to let the quality of the meat shine through. However, you can also experiment with other seasonings such as garlic powder, onion powder, paprika, or your favorite steak rub.
For optimal flavor penetration, season the tenderloin generously at least 30 minutes before cooking, or even better, the night before. This allows the salt to draw out moisture and create a flavorful crust during cooking.
Cooking Methods for Perfect Beef Tenderloin
Beef tenderloin is a versatile cut of meat that can be cooked using various methods. The best method depends on your preferences, equipment, and the desired outcome.
Roasting: The Classic Approach
Roasting is a classic method for cooking a whole beef tenderloin. It’s relatively hands-off and allows you to cook the tenderloin to your desired level of doneness.
Preheat your oven to 425°F (220°C). Place the seasoned and tied tenderloin on a roasting rack in a roasting pan. Roast for 20-25 minutes, then reduce the oven temperature to 325°F (160°C) and continue roasting until the internal temperature reaches your desired level of doneness (see temperature guide below).
Use a meat thermometer to monitor the internal temperature. Insert the thermometer into the thickest part of the tenderloin, avoiding bone or fat.
- Rare: 125-130°F (52-54°C)
- Medium-Rare: 130-135°F (54-57°C)
- Medium: 135-140°F (57-60°C)
- Medium-Well: 140-145°F (60-63°C)
- Well-Done: 145°F+ (63°C+)
Remove the tenderloin from the oven and let it rest for at least 10-15 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful roast.
Reverse Sear: The Modern Technique
The reverse sear method involves cooking the tenderloin at a low temperature in the oven followed by a quick sear in a hot pan. This technique results in a perfectly even cook throughout the tenderloin with a beautiful crust.
Preheat your oven to 250°F (120°C). Place the seasoned and tied tenderloin on a roasting rack in a roasting pan. Cook until the internal temperature is about 15-20 degrees below your desired final temperature.
Remove the tenderloin from the oven and let it rest for 10-15 minutes. While the tenderloin is resting, heat a cast-iron skillet over high heat until it’s smoking hot. Add a tablespoon of oil with a high smoke point, such as avocado oil or grapeseed oil.
Sear the tenderloin on all sides for 1-2 minutes per side, until a deep brown crust forms. Remove the tenderloin from the skillet and let it rest for a few minutes before slicing.
Grilling: For Smoky Flavor
Grilling beef tenderloin adds a delicious smoky flavor. You can grill the whole tenderloin or cut it into steaks.
Preheat your grill to medium-high heat. Season the tenderloin or steaks with salt, pepper, and any other desired seasonings.
If grilling the whole tenderloin, place it on the grill and cook for 15-20 minutes, turning occasionally, until the internal temperature reaches your desired level of doneness.
If grilling steaks, cook for 3-5 minutes per side for medium-rare, or longer for more well-done.
Let the tenderloin or steaks rest for a few minutes before slicing.
Sous Vide: Precision Cooking
Sous vide is a cooking method that involves immersing food in a temperature-controlled water bath. This technique allows for precise temperature control, resulting in perfectly cooked beef tenderloin every time.
Preheat a water bath to your desired internal temperature (see temperature guide above). Season the tenderloin with salt, pepper, and any other desired seasonings.
Place the tenderloin in a vacuum-sealed bag and remove any air. Submerge the bag in the water bath and cook for 1-4 hours, depending on the thickness of the tenderloin.
Remove the tenderloin from the bag and pat it dry with paper towels. Sear it in a hot skillet with oil for 1-2 minutes per side to create a beautiful crust. Let it rest for a few minutes before slicing.

Can I freeze a whole, uncooked Costco beef tenderloin?
Yes, freezing an entire, uncooked Costco beef tenderloin is an excellent way to preserve it for later use. The best method involves preparing the tenderloin for freezing immediately upon purchase. Remove it from the original packaging and pat it dry with paper towels. Trim any excess fat or silver skin that you wouldn’t want to cook with.
Wrap the tenderloin tightly in several layers of plastic wrap, ensuring there are no air pockets. Then, place the wrapped tenderloin in a freezer-safe bag, squeezing out as much air as possible before sealing. Label the bag with the date and contents.
