Whether you prefer your steak rare, medium, or well-done, this guide will equip you with the knowledge to cook a filet that’s tender, juicy, and bursting with flavor every time.
Preparing the Filet for Cooking
Before placing the filet in the cast iron skillet, it is essential to prepare the meat properly to ensure even cooking and optimal flavor. Start by bringing the filet to room temperature; remove it from the refrigerator about 30 to 60 minutes before cooking. This helps the steak cook more evenly and prevents the outside from overcooking while the inside remains underdone.
Pat the filet dry thoroughly with paper towels. Moisture on the surface of the steak will steam the meat rather than sear it, hindering the development of a rich crust. Once dry, season the filet generously with kosher salt and freshly ground black pepper. You can also add garlic powder or smoked paprika if desired, but keep the seasoning simple to highlight the natural flavors of the beef.
For an extra layer of flavor and to promote even browning, lightly coat the filet with a high smoke point oil such as avocado, grapeseed, or canola oil. This oil will help conduct heat and create a desirable crust without burning.
Heating and Using the Cast Iron Skillet
A well-heated cast iron skillet is critical for cooking a filet perfectly. Place the skillet on your stovetop over medium-high heat and allow it to heat thoroughly. This process usually takes 5 to 7 minutes. You can test the heat by flicking a few drops of water into the pan—if they sizzle and evaporate immediately, the skillet is ready.
Add a small amount of oil to the skillet just before adding the filet. The oil should shimmer but not smoke excessively. If the oil begins to smoke heavily, reduce the heat slightly to prevent burning.
Place the filet gently into the skillet, laying it away from you to avoid splatters. Do not move the steak during the initial searing phase; this allows a crust to form, locking in juices and flavor.
Searing and Cooking the Filet
Searing the filet in the cast iron skillet creates a flavorful crust that enhances the steak’s texture and taste. Follow these steps to sear and cook the filet to your preferred doneness:
- Sear the first side for 2 to 3 minutes without moving the steak.
- Flip the filet using tongs and sear the other side for an additional 2 to 3 minutes.
- For thicker filets, sear the edges by holding the steak with tongs and rolling it along the skillet’s surface.
- Reduce heat to medium or transfer the skillet to a preheated oven (around 400°F/204°C) to finish cooking if needed.
To accurately determine doneness, use an instant-read meat thermometer. Insert it horizontally into the thickest part of the filet without touching bone or fat.
| Doneness | Internal Temperature | Approximate Cooking Time (after searing) | Texture Description |
|---|---|---|---|
| Rare | 120-125°F (49-52°C) | 2-3 minutes | Cool red center, very soft |
| Medium Rare | 130-135°F (54-57°C) | 3-4 minutes | Warm red center, tender and juicy |
| Medium | 140-145°F (60-63°C) | 4-5 minutes | Pink and firm center |
| Medium Well | 150-155°F (65-68°C) | 5-6 minutes | Mostly brown with slight pink |
| Well Done | 160°F (71°C) and above | 6+ minutes | Brown throughout, firm |
Enhancing Flavor with Butter and Aromatics
Once the filet is nearly cooked to your desired temperature, adding butter and aromatics can elevate the flavor and richness of the steak. Lower the skillet heat to medium-low and add a couple of tablespoons of unsalted butter. As it melts, add fresh herbs like rosemary, thyme, and crushed garlic cloves.
Tilt the skillet slightly and use a spoon to baste the filet continuously with the melted butter and herb mixture. This technique infuses the meat with subtle herbal notes and helps keep the exterior moist and flavorful.
Continue basting for 1 to 2 minutes, ensuring the butter does not burn. This stage is also ideal for adding a splash of lemon juice or a dash of Worcestershire sauce if you prefer an additional flavor boost.
Resting the Filet After Cooking
Resting the filet after cooking is an essential step to achieve a juicy, tender steak. Remove the filet from the skillet and place it on a warm plate or cutting board. Tent it loosely with aluminum foil and allow it to rest for 5 to 10 minutes.
During this time, the juices redistribute throughout the meat, preventing them from spilling out when you cut into the steak. Resting also helps the internal temperature stabilize, sometimes rising a few degrees, so consider this carryover heat when determining doneness.
Avoid cutting the filet immediately after cooking to maintain optimal moisture and texture. After resting, slice the filet against the grain for the best tenderness.
