Few dishes feel as luxurious as a beautifully cooked filet mignon. Cut from the most tender section of the beef tenderloin, this steak is prized for its buttery texture and delicate flavor. Because it’s such a premium cut, the key is simple: treat it with care and let the quality of the meat shine.
This method focuses on building flavor through a rich sear, followed by a quick butter baste infused with garlic and rosemary. The result is a steakhouse-quality experience made right in your own kitchen — crisp on the outside, tender and juicy on the inside.
Ingredients
- Filet mignon steaks (about 6–8 ounces each)
- Olive oil (high smoke point)
- Kosher salt
- Freshly ground black pepper
- Unsalted butter
- Fresh rosemary sprigs
- Garlic cloves, lightly crushed
Preparation for Filet Mignon Recipe
1. Bring steaks to room temperature
Remove the steaks from the refrigerator roughly 30–40 minutes before cooking. This helps ensure even cooking. Pat dry and season generously with salt and pepper on all sides.
2. Heat the pan
Place a cast iron skillet over high heat. Once very hot, add a small amount of olive oil. The oil should shimmer but not smoke excessively.
3. Sear the steaks
Carefully place the steaks in the pan. Sear without moving for about 2 minutes to develop a deep golden crust. Rotate briefly to brown the edges.
4. Butter baste
Flip the steaks and immediately add butter, garlic, and rosemary to the pan. As the butter melts, tilt the skillet slightly and spoon the aromatic butter over the steaks for about 1 minute.
5. Finish in the oven
Transfer the skillet to a preheated 400°F (200°C) oven. Cook for several minutes depending on your preferred doneness (use a thermometer for accuracy).
6. Rest before serving
Move the steaks to a plate and allow them to rest for at least 5 minutes. This keeps the juices locked inside.
Serving Ideas
Filet mignon pairs beautifully with classic sides like roasted vegetables, mashed potatoes, mushrooms, or a fresh crisp salad. For extra indulgence, finish with compound butter or a silky sauce.
