I cannot remember the last time I had filet mignon with herb butter. A seriously dense cut of steak, it’s richness heightened by butter and herbs. It’s such a grown-up meal, great for the holidays and any celebratory dinner.

I used a grill pan to cook this filet mignon with herb butter dish and I cooked the steaks on a high heat. I’m sure you know that this cut of meat should not be overcooked, here’s some guidance to arrive at the right temperature:

  • 3 mins either side = rare
  • 5 mins either side = medium
  • 7 mins either side = medium/well

I would advise against cooking this cut of meat to well done, unless you plan on cooking it butterflied, for which you should cook for the same amount of time as medium or medium/well above, dependent upon the thickness of the portions. My steaks were approx. 2 inches thick.

So what do you serve with filet mignon with herb butter? Well, as you can see from the pic above, I served mine with twice cooked potatoes, skin on. First baked and then sautéed to a crisp – recipe to follow. Mashed potatoes will be a hit with this dish too, but if you’re avoiding carbs, veggies tossed in truffle oil will make you and your guests smile.

If you’re thinking of serving more than one meat dish for the holidays, note that filet mignon is a dense cut of meat. To avoid a food coma, I would suggest that once the filets are cooked, cut them in half and serve sparingly.
