Grilled Beef Filet with Tarragon Garlic Butter

We didn't do anything for my birthday this year because I had two overnight cooking events back to back.  First I did a full BBQ spread for a co-worker's wedding shower at work and then left straight from there to cook at the Jim Beam Classic BBQ contest in Springfield, KY.  When I got home, Alexis surprised me with a nice pair of Certified Angus Beef filet - because, surprise surprise, I like to grill for my birthday, Father's day, and the like.

Bearnaise sauce is a personal favorite for beef filet but being worn out from days of cooking, I didn't feel like doing all of that whisking.  Instead I made a "bearnaise-ish" compound butter using some fresh tarragon and garlic instead of shallot.  Tarragon has a strong presence so it's best to use it sparingly and to add it at the end of the cooking process, perfect for a compound butter.

You can just use regular black pepper but I like the flavor that the smoked black pepper adds.  We often cold smoke whole peppercorns ourselves.  It just takes a few hours and the whole peppercorns hold the smoke pretty well in storage.  When you grind them fresh, it gives a nice smoky kick.

Grilled Beef Filet with Tarragon Garlic Butter

Published 10/05/2015


  • 4 8-10 ounce CAB beef filet
  • NMT Beef Rub or your favorite beef rub
For the Tarragon Garlic Butter
  • 1 stick unsalted butter, softened
  • 1 clove garlic, minced
  • 6 leaves fresh tarragon, torn into pieces
  • 2 pinches kosher salt
  • 2 pinches smoked black pepper


  1. Mash together the butter, minced garlic, tarragon, salt and pepper in a small bowl.  Spoon this onto a sheet of wax paper and form into a log.  Refrigerate for at least and hour before serving.
  2. Set up your grill for direct heat and preheat your grill to 450°f.
  3. Lightly oil the steaks with a high temperature oil, such as; canola or peanut oil, and season liberally on both sides.
  4. Grill the steaks about 4 1/2 to 5 minutes per side to an internal temperature of 125-130°f for medium rare.
  5. Remove the steaks from the grill and immediately top with 1-2 slices of the compound butter.  The carry-over cooking will melt the butter and bring the internal temperature up about 5 more degrees for a perfect medium rare.
  6. Serve quickly while the butter is still melting. 
Yield: 4 servings

Before grilling the steaks, I used the Grill Dome to bake the potatoes at 450°f for about an hour and then switched to direct heat for the steaks.  That indirect piece is a cast iron plate setter from Innovations by Chance.  I thought about just flipping it and cooking the steaks on the griddle side - that works well too.

In general, I don't season my steaks until the last minute before they go on the grill.

I spoon the butter into the rough shape of a stick of butter.  I roll the wax sheet over the butter and tuck it back tightly like this.  Then I just roll it up and tuck the edges under.

Waste not, want not - I used the stem from the tarragon to help season the brown butter for the carrots.

Mise en place - I make the brown butter ahead of time on the stove top and then just use it to finish off cooking some parboiled carrots.

I used a coarse grind of my NMT Beef Rub but you can use whatever you like. Montreal Seasoning is a popular one.  Simply salt, pepper, and granulated garlic are also easy and effective.

I didn't measure how much rub I used, just sprinkle an even, moderate coating like this.

While the steaks came off and rested, I finished the carrots in the brown butter and then tossed in some brown sugar, salt, and pepper at the last minute.

Tip:  Take your compound butter back out of the fridge a bit before using so it melts easier.

Serving Ideas
Here are a few shots from the wedding shower that I cooked overnight on Thursday.  I had everything cooked (except the burgers and dogs) and transported it all in Cambro's to the office.  I sliced the brisket and pulled the pork there.  That keeps it warmer and retains the juices better than if I sliced/pulled it at home which starts it drying out.

Just did this on the computer, printed it out and Alexis decoupaged it onto a canvas frame.

Set up buffet style - excuse my blurry phone picture - I was in a hurry.

Here's how I did my "bbq sauce bar".  I got the little chalk clothes pins at AC Moore for something like 8 pieces for $3.

  1. Good looking BD meal Chris - I like how you did the carrots

  2. Now that's my kind of birthday meal! The steak looks perfect and topped with that butter has me drooling. I also love that you finished the carrots off with browned butter. I guess I must love butter! Great looking meal. Happy belated birthday.
