Beef tenderloin is a popular cut of meat known for its tenderness and rich flavor. One of the best ways to prepare this delicious cut is by using a cast iron skillet. The skillet’s ability to evenly distribute heat and retain it makes it the perfect tool for cooking beef tenderloin to perfection. In this article, we will guide you through the steps of cooking a mouthwatering beef tenderloin in a cast iron skillet.

Choosing the Right Cut

Before you start cooking, it’s essential to choose the right cut of beef tenderloin. Look for a piece that is bright red in color with minimal fat marbling. The tenderloin should be well-trimmed and free from silver skin. This will ensure a tender and flavorful result.

Preparing the Beef Tenderloin

Before cooking, it’s important to prepare the beef tenderloin. Start by patting the meat dry with paper towels to remove any excess moisture. This will help the meat sear properly in the skillet. Season the tenderloin generously with salt, pepper, and any other desired seasonings such as garlic powder or rosemary.

Preheating the Cast Iron Skillet

Place the cast iron skillet on the stovetop over medium-high heat. Allow it to preheat for a few minutes until it becomes hot. You can test the skillet’s readiness by sprinkling a few drops of water on the surface. If the water sizzles and evaporates immediately, the skillet is ready for cooking.

Searing the Beef Tenderloin

Carefully place the seasoned beef tenderloin in the hot cast iron skillet. Allow it to sear undisturbed for about 3-4 minutes on each side. This will create a beautiful crust and seal in the juices. Use tongs to flip the tenderloin and repeat the searing process on all sides.

Finishing in the Oven

Once the beef tenderloin is evenly seared, transfer the skillet to a preheated oven set to 425°F (220°C). Cook the tenderloin for about 10-15 minutes or until it reaches your desired level of doneness. Use a meat thermometer to ensure the internal temperature reaches 135°F (57°C) for medium-rare or 145°F (63°C) for medium.

Resting and Carving

After removing the skillet from the oven, let the beef tenderloin rest for at least 10 minutes. This allows the juices to redistribute throughout the meat, resulting in a tender and juicy final product. Once rested, slice the tenderloin against the grain into thick slices for serving.

Serving Suggestions

Beef tenderloin pairs well with a variety of side dishes. Consider serving it with roasted potatoes, steamed vegetables, or a fresh salad. For added flavor, you can also make a delicious pan sauce by deglazing the skillet with red wine or beef broth and reducing it until thickened.


Cooking beef tenderloin in a cast iron skillet is a simple yet impressive way to prepare this delectable cut of meat. With the right techniques and a little patience, you can achieve a perfectly cooked, tender, and flavorful beef tenderloin that will impress your guests and satisfy your taste buds.
