How to Grill Filet Mignon

Cooking filet mignon on the grill is really simple, but I’ll be honest with you, I swore off grilling filet a few years ago when I discovered the stove top to oven method. It’s simply the best way to cook a perfectly even and juicy steak. With that said, the stove/oven method is not always realistic if you’re cooking several steaks at a BBQ or you’re just in the mood for grilling in the summer.

The most critical advice I have for you is to not overcook your filet. No kidding, Shawn. Yes, it’s obvious but 1-2 minutes can make a HUGE difference in the final temp. 5 minutes per side on medium-high heat is the sweet spot for perfect medium rare steak, adding an additional minute per side for each level of doneness.

  • Rare: 4 minutes per side
  • Medium rare: 5 minutes per side
  • Medium: 6-7 minutes per side
  • Medium well: 8+ minutes per side

Use your phones timer to be exact, it always yields consistent results! Also, a simple digital thermometer is absolutely the best way to confirm the internal temp, unless you’re a wizard who can tell just by touching it (I am not).

When I grill filet, I like to season with a rub of finely chopped fresh rosemary and a healthy dose of salt and pepper. Rub it into the filet with a tiny drizzle of olive oil until evenly coated on all sides. Serve topped with garlic and herb butter and you’ll be well on your way to flavortown, baby.

Who said you couldn’t cook a perfectly even filet on the grill?!
