Medium-Rare Filet Mignon & Sautéed Mushrooms

Bruce knows how to cook a medium-rare filet mignon on a grill, and it is perfect every time. We really like the flavor of the steak to shine, so for seasoning,  we use just a course mixture of crushed peppercorns and kosher salt with a little olive oil.

If you prefer your steak well done, just add a few minutes to the cooking time. We both enjoy a medium-well filet mignon, but Bruce likes it on the redder side.

What you will need for medium-rare filet mignon & sautéed mushrooms:

  • Filet Mignons
  • Whole black peppercorns
  • Kosher salt
  • Olive oil
  • Butter
  • Mushrooms
  • Butter
  • Salt and Pepper
  • Cast Iron Pan
  • Foil

What are internal temperatures for steak?

  • RARE: 125° F 52 ° C: Cool red center, tender texture.
  • MEDIUM RARE: 135° F 57 ° C: Warm red center, perfect steak texture.
  • MEDIUM: 145° F 63 ° C: Hot, slightly pink center, firmer texture.
  • MEDIUM WELL: 150° F 66 ° C: Mostly brown center, firmer texture.
  • WELL DONE: 160° F 71 ° C: No color, very firm and much drier.

How do I ensure I do not over-cook my steak?

Pull the steak off the heat 5 degrees lower than final temperature for your desired doneness. Bruce has been cooking steaks for over 30 years, so he does it by feel. For medium-rare, it should feel like your cheek: tender and soft but still fleshy. If you want a medium steak, touch your chin: The steak should still be tender, but with some resistance. If unsure, use a meat thermometer. 

What should I serve with my steak?

We like to serve our steak with piping hot double cheddar popovers and asparagus! A nice side salad also is the perfect pairing!

Time to grill!

  • Prepare your grill. Place the mushroom pan on the hot grill. Stir the mushrooms occasionally so they do not burn.
  • Place steaks on grill. At the same time, place a cast iron skillet on grill.  Sear steaks for 2 minutes on each side, for rare, and 3 minutes each side for medium-rare.
    2 Filet Mignon 6-8 ounce portions
  • Now place the steaks in the cast iron pan that has been heating up on the grill. Top each steak with 1 tablespoon of butter and cook for 2 minutes. Turn the steaks over in the pan, top with remaining butter and remove the steak pan from the heat and cover with foil. After 2 minutes remove the steaks from the pan, place on a plate and cover with foil. Allow steak to rest for 6-8 minutes.

Notes

You will remove the steak when internal temperature is 5 degrees lower than the final doneness. You will want a final temperature of 130°-135°F for medium-rare.
