Understanding Filet Mignon
Filet mignon is a cut from the tenderloin of a steer or heifer. As one of the most desirable cuts of meat, it is known for its tenderness and mild flavor. To achieve a perfectly grilled filet mignon, it's essential to start with high-quality meat.
When shopping for filet mignon, look for steaks that are an even thickness with good marbling. Marbling, or the small streaks of fat running through the meat, ensures the steak remains moist and flavorful during grilling.

Essential Tools and Ingredients
Ingredients
- 2 filet mignon steaks (1.5 - 2 inches thick)

- Freshly ground black pepper
- Kosher salt
- Herbs (like rosemary or thyme)
- Garlic (optional)
- Butter

Prepping the Grill

Seasoning the Filet Mignon
Proper seasoning is essential for a flavor-packed filet mignon. Begin by bringing the steaks to room temperature, which should take around 30 minutes. Next, lightly brush each steak with olive oil. Generously season both sides with kosher salt and freshly ground black pepper. For added flavor, consider adding a sprig of herbs like rosemary or thyme, and some garlic.
Direct and Indirect Grilling
Grilling filet mignon is all about mastering the balance between direct and indirect heat. Start by searing each side of the steak over direct heat for 2-3 minutes. Searing locks in the juices and creates a delicious crust. After searing, move the steaks to the cooler side of the grill (indirect heat) to finish cooking. This method ensures the interior reaches the desired level of doneness without burning the exterior. For more on grilling techniques, check out our article on grilling techniques.
Using a Meat Thermometer
Investing in a good meat thermometer is essential when learning how to cook filet mignon on a charcoal grill. Insert the thermometer into the thickest part of the steak to check the internal temperature. For a perfect medium-rare steak, aim for an internal temperature of 130-135F (54-57C). Remember, the steak will continue to cook slightly even after being removed from the grill.
The Resting Phase
One of the most crucial steps in ensuring a juicy filet mignon is allowing the steaks to rest. After removing the steaks from the grill, place them on a cutting board and loosely cover with aluminum foil. Allow the steaks to rest for at least 5-10 minutes. Resting enables the juices to redistribute throughout the meat, resulting in a tender and flavorful steak.
Finishing Touches
For the finishing touch, top each steak with a pat of butter just before serving. The butter will melt over the hot steak, adding richness to every bite. If you've used herbs and garlic for seasoning, you can remove them or leave them on for an added burst of flavor.
Carving and Serving
When it comes to serving filet mignon, presentation is key. Use a sharp knife to slice the steak against the grain for maximum tenderness. A good knives set, like this knives set ensures precise cuts and enhances the presentation of your meal. Pair the filet mignon with your favorite sides, such as garlic mashed potatoes, roasted vegetables, or a crisp salad. For more serving ideas, check out our serving suggestions.
