Grass-fed Beef Filet and Boxty with Guinness Mustard Sauce

Updated: Feb 24, 2022

Chew on this delectable review of an Irish meal that you don't have to travel across the pond for! Greensbury's Organic Grass-Fed Top Sirloin & Applewood Smoked Bacon are paired beautifully with Chez Gael’s Mouthwatering Beef Filet Boxty. You'll want everything in your mouth after savoring every bite - including those yummy greens (or should we say "top sirloin"?).


  • 24oz organic, grass-fed top sirloin filet

  • 4 slices organic applewood smoked bacon

  • 1 Tbsp Guinness

  • Mustard seed

  • 4oz butter

  • 4 shallots chopped small

  • 1/2lb raw potatoes

  • 1/4lb button mushrooms

  • 1/2lb mashed potatoes

  • 1 glass red wine

  • Flour

  • Salt & pepper (to taste)

  • Watercress greens



  1. Wash the raw potatoes and grate them into a linen cloth. Wring them tightly, catching all the liquid in a bowl.

  2. Leave the liquid in the bowl until the starch sinks and the water on top is clear.

  3. Pour off the water and scrape the starch on to the potatoes. Season with salt and mix well.

  4. Into this add enough flour to make pliable dough. Knead and roll out and cut in circles (like pancakes).

  5. Fry on a greased griddle or pan until brown on both sides, keep hot.


  1. Skewer or tie the bacon around the filets. Season to taste.

  2. Fry together in butter.

  3. When cooked, put aside (keep hot).


  1. Fry the mushrooms and shallots in the same pan. Use any grease remaining.

  2. Add the red wine and reduce by half.

  3. Finally, add the mustard seed.


  1. Place Boxty on serving dish with filets on top.

  2. Pour sauce over filets. Garnish with watercress.
