Filet mignon is such a beautiful cut of meat. Because of where this muscle lies on the cow, just under the backbone, it doesn’t get worked much, which is why it’s so tender.

And what makes it even more special is that it’s a lot leaner than a ribeye with only about 7 grams of saturated fat, compared to the ribeye’s 28 grams. 

Because this meat is so succulent, I like it cooked rare to medium rare. At this temp, it melts in your mouth like butter. But I recognize that some people just can’t do pink meat, which is why the below recipe can be adapted for all meat lovers. 

HOW TO GRILL FILET MIGNON

Let’s start with the seasoning. All you really need is salt and pepper. I like using kosher salt and course ground black pepper, because both provide a little texture when the crust forms. 

I don’t measure here. Just sprinkle until they have a dusting on all sides.

Season the steaks about 30 minutes before you’re going to put them on the grill and leave them on the counter. This allows them to lose the chill from the fridge, so they cook more evenly. Filet mignon’s are usually 1 1/2 to 3 inches thick. If they’re too cold, the outer edges will cook too quickly compared to the center. 

I love grilling filet mignon on the sear station on my Aspire gas grill. It can get up to 1,000F degrees. I set it for medium-high and place the steaks on after it has heated up for a good 15 minutes. 

The ceramic plates create a crust that is just divine,  especially with the coarse black pepper.

HOW LONG TO COOK FILET MIGNON

There’s not an exact formula for this, but I can give you some tried and true pointers. 

Bottom line is that the cook time is going to depend on the thickness of your steak, how cold it is when you put it on the grill, how hot your grill is and how done you like it cooked. 

Fortunately, we can control all of those things. 

For a 1 1/2-2″ steak that’s been sitting on the counter for about 30 minutes, it will take about 4 minutes per side over medium-high heat to reach rare to medium rare. Add another minute per side to reach medium, and another minute per side for medium well. And just keep going for well done.

The best way to know the exact temp is to use a digital thermometer. Pierce the probe into the side of the steak like shown in the picture. This will give you the most accurate reading. I pull my steak at about 127F for rare to medium rare. Keep in mind it will rise a few degrees as it rests on the counter. 

WHAT IS PEPPERCORN SAUCE

Since I’ve kept the filet very natural with just salt and pepper, I can dress it up with a luxurious sauce. 

Peppercorn sauce, also called au poivre (in French) is a creamy sauce spiked with brandy or cognac.

As the name implies, it starts with whole peppercorns. You can grind some with a pepper grinder, but it’s a lot quicker to place them in a bag and crush them with a rolling pin or heavy can.

Start the sauce by toasting the freshly crushed peppercorns in a dry sauce pot over medium-high heat. You can do this on the grill or over a burner. Toasting them will bring out their essential oils.

Next, add the butter and saute some diced shallots, until they’re tender. Carefully, pour in the beef broth and brandy. 

You want to bring everything to a rapid boil for about 7 minutes. This allows the sauce to reduce, so it will thicken.

When you add the cream, it too will boil. You need to stir it as it cooks, so it doesn’t form a skin on top. After about 5 minutes, it will thicken and coat the back of a spoon.

Remove it from the heat and whisk in two tablespoons of butter. Oh it’s so heavenly. I could almost drink this stuff. 

You can make the sauce in advance and keep it over low heat on the stove. Just be sure to stir it occasionally or it will form a skin. No big deal though. You can whisk it away.

After the steaks have rested for a few minutes, spoon some of the sauce right over the steaks and enjoy.
