For the Giardiniera

  • chop all of your vegetables into bite size pieces (you don't want them to be too big).
  • prepare a brine by dissolving the kosher salt in the water. Let it cool
  • Once the brine has cooled pour the brine over the vegetables (make sure the brine covers all the vegetables) and refrigerate overnight.
  • The next day taste the vegetables. If it doesn't seem salty enough continue to brine another 6-12 hours. The vegetables should be crispy and taste a little salty.
  • Once they have been properly brined, drain the brine and rinse the vegetables. If you find that they are too salty you can soak the vegetables in cool water for an hour or 2.
  • Prepare the Giardiniera dressing by combining all of the ingredients and whisking well.
  • In a bowl, combine the dressing and the drained vegetables. Refrigerate for 48 hours.
  • This will last 2-3 week in your refrigerator or can be frozen in a freezer friendly container.

For the Roast Beef

  • Tie your roast up and coat with olive oil
  • combine all of the roast's spices and herbs together and rub on the roast
  • Marinate for 1 hour at room temperature.
  • Preheat oven to 450f (232c)
  • Place seasoned roast on a roasting rack and roast for 20 minutes
  • After 20 minutes reduce the heat to 325f (163c) and roast for another 30 minutes or until the internal temperature reaches 125f (53c).
  • Once your target temperature has been met, remove from oven and let your roast rest for 30-40 minutes covered.
  • Once cooled refrigerate overnight before slicing thinly against the grain. (optional) Once sliced you can chop your roast beef into even smaller pieces.

For the Au Jus

  • combine all of the ingredients for the au just and heat on a medium heat for 10 minutes. Taste and adjust for seasonings as necessary
