Substitutions and Variations

• Drizzle with olive oil instead of butter.
• Marinate filet mignon in your favorite bottled marinade.
• Use other seasonings, such as a steak blend or your favorite blend.

How To Grill Filet Mignon

Here are the step-by-step instructions for grilling filet mignon:

2. 30-40 minutes before grilling, remove from the fridge to bring to room temperature.

3. Grease grill grates. Preheat your grill to 450 degrees F. Create two zones - one side with direct heat (gas grill burners on or charcoal grill coals underneath), the other indirect heat (no burner or no coals). Close the lid.

6. Remove filets from heat, place on a plate, and tent with foil for 10 minutes before serving. The temperature of the steaks will continue to rise by about 5 degrees.

7. Serve steaks with herb butter or other favorite steak topping.

Timing is everything: How long to grill a filet mignon.

Once you have created two zones (indirect heat and direct heat) and your grill is preheated to 425 degrees - sear the filet mignon steaks for 2 minutes on each side over direct heat. Move to the indirect side and continue cooking filet mignon 3-4 minutes on each side or as soon as their internal temperature reaches 130 degrees F. Remove from grill and let rest with foil tented over the top for 10 minutes. The grilled filet mignon will finish cooking on the plate, reaching 135 degrees F--the perfect medium rare!

Tips for Grilling Filet Mignon

• Have the grill temperature at 450 degrees before even considering searing the steak.
• Use an instant-read meat thermometer to test doneness of filet mignon on the grill. Removing the steaks at the exact temperature is key to the perfect done steak.
• Seasoning with salt and pepper several days before grilling allows the meat to tenderize and get the best flavor.
• Putting your steak on a rack and in the fridge the night before grilling helps dry the exterior or the steak to create the perfect crust on the outside and an extra juicy center.
• Let your steaks rise to room temperature 30-45 minutes before you cook filet mignon to allow the steaks to cook evenly for the most precise doneness.

What We Love to Serve with Filet Mignon on the Grill

• Top steaks with garlic butter with herbs or compound butter. Flavored butters add fresh herb flavor, richness from the butter, and give you a restaurant experience right at home. Purchase from the grocery store or make your own--it's super easy!
• Carmelize onions and mushrooms in butter to top your steak - a classic steak topping.
• Top with blue cheese crumbles, or serve with a creamy sauce such as blue cheese or dill.
• Garnish with fresh herbs such as chives, parsley, dill, rosemary, or thyme.

Storing and Reheating Grilled Filet Mignon

Once your steak is cooled, transfer it to an air-tight container and store it in the fridge for up to 3 days.

For the best reheating of any steak is to store it whole and reheat it whole if possible. Put your steak on a plate and add a pat of butter on top. Microwave on half power for 30-second intervals until the steaks' internal temperature reaches at least 135 degrees. Let rest for 5 minutes before cutting to serve.
