Cut from | Whole tenderloin | Small portion of tenderloin |
Texture | Lean, slightly firm | Buttery soft |
Best Cooking Method | Roasting, grilling | Pan-searing, grilling |
If you’re cooking for a group, a beef tenderloin recipe is ideal. If you want an individual, high-end steak, filet mignon is a great choice.
Choosing the Perfect Beef tenderloin steak internal doneness
Not all beef tenderloin cuts are equal. USDA Prime beef has the highest quality due to its marbling, followed by USDA Choice and Select. Look for a tenderloin with consistent thickness to ensure even cooking.
For family-friendly steak recipes, buy a whole tenderloin and trim it yourself. If you’re short on time, ask your butcher to trim and tie the roast for you. Slicing beef tenderloin after cooking ensures that each guest gets a tender, juicy piece.
Essential Equipment for Cooking Beef tenderloin steak internal doneness

Cooking a tenderloin steak requires the right tools. A meat thermometer is a must for accuracy. Using an oven thermometer ensures your steak reaches the ideal oven temperature for a perfect cook.
A cast-iron skillet works best for high-temperature searing, while a roasting pan is great for an oven-roasted beef recipe. Other essentials include a sharp knife, butcher’s twine, and a basting brush for butter.
The Secret to the Perfect Brown Crust
A perfect steak crust forms when the steak is dry before cooking. Dry brining with salt enhances flavor and helps create a crisp sear. Blackening seasoning for meat adds extra depth to the crust.
Using high-temperature searing, cook each side for 2-3 minutes before moving it to the oven. This technique locks in juices while ensuring a crispy crust. A steak grilling technique using direct heat will also achieve this effect.
