Beef Roast with Homemade Béarnaise Sauce

We were honoured to have our great friends Fiona and Stu join us for the first ever beef roast done on the Big Green “Asian” Egg last night.  Despite all other attempts at cooking beef, this one was by far…not exaggerating, the BEST piece of beef we’ve ever managed! As always, to get the best choice of beef cuts, we visited our friends at Hubers on Dempsey Road.  After a bit of humming and hawing, we decided that we’ll got with the Ribeye cut as opposed to the tenderloin cut – two reasons really:  more marbling on the ribeye and the cost of the tenderloin was a bit on the crazy side.  We ordered just under 1.5 kg of ribeye to feed 5 very hungry people.

The recipe I used was straight from the BGE Cookbook, page 60 to be precise.  The instructions were simple enough but aha….there was a challenge too…Béarnaise Sauce!  Now, I’ve never tried Béarnaise before and thankfully, on the first attempt, it came out as a perfect compliment to an incredible piece of beef.  So do try this sauce and try the roast the way we’ve listed it below – I guarantee you won’t go back to buying individual steaks!

Ingredients for the roast:

  1. 1 x 1.5 kg cut of ribeye beef

  2. 1 tbsp olive oil

  3. 2 tsp kosher salt

  4. 2 tbs ground black pepper

Ingredients for the Béarnaise Sauce:


  1. 1.5 oz of fresh tarragon sprigs

  2. 1 large egg yolk

  3. 1/2 cup white wine vinegar

  4. 1 shallot, sliced thinly

  5. 5 black peppercorns

  6. 1 cup unsalted butter (melted)

  7. 1 tsp freshly squeezed lemon juice

  8. Pinch of cayenne pepper

  9. kosher salt (to taste)

  10. ground black pepper (to taste)

Set your grill up for direct cooking and stabilize the temperature at 400 degrees F.  I used two fist sized pieces of mesquite wood added into the firebox along with the hardwood charcoal.  Let the fire settle down for a good while, to the point where no smoke is coming out – I learned recently that smoking fires don’t add any more flavour to grilled meat, get it all nice and hot and not smoking for best results!
