Marinade

  • 3 Cloves of Garlic finely chopped
  • 1 tbsp Whole Grain Mustard
  • 4 tbsp Olive Oil
  • 1 tsp Onion Powder

Instructions
 

Dry Marinade

  • Slice the roast between the bones and the meat. Leave about an inch or so still intact to keep the roast in one piece.
  • In a bowl mix all dry ingredients.
  • Pour Worcestershire Sauce over the whole roast. Be sure to get in the crevice between the roast and the bones.
  • Sprinkle the dry ingredients on every part of the roast. Again, don't forget to get in the crevice between the roast and the bones. Sprinkle and rub the seasoning on the roast until it can not hold anymore. Don't be afraid to use it all.
  • Place the Roast on a wire rack in a pan and do not cover it. Put it in the fridge for 24 to 48 hours to let the seasonings work into the meat.

Cooking Day

  • You will want to bring your roast out of the fridge and let it sit uncovered until it comes to room temperature. This could take anywhere between 4 to 6 hours depending on how cold your house is.

Bottom of the Pan

  • Turn the oven on to 250º while you prepare the roast to be cooked. If your oven. has options with different types of cooking settings you will want to set it on BAKE.
  • You will want to lay out all your ingredients randomly in the pan.
  • Drizzle the olive oil over the ingredients
  • Place the roast on top of the ingredients

Marinade

  • Mix the ingredients together in a small bowl.
  • Slowly pour the ingredients over the roast.
  • Using your hands try to rub the ingredients around on the sides to give a nice even coat.

Cooking the Roast

  • Once the oven has been preheated place the roast inside the oven on the middle rack.
  • The roast will need to cook until it hits an internal temperature of 118º. This should take about 30 min per pound. BUT do not be afraid to check it throughout the process. Some of our ovens just cook hotter than others.
  • Once the internal temperature hits 118º you need to pull it out of the oven and let it sit at room temperature for 30 min to 1 hour to rest.

Reverse Sear * See notes below

  • Now you are going to put it back into the oven to sear the outside. You need to set the oven at 500º. Let the oven come to temp.
  • Place your roast back in the oven to do a reverse sear. This should take about 10-15 min. You will see a nice browning to the crust happen in this stage. Be sure to watch it and not let it burn.
  • Pull the roast out and it is ready to serve. You do not need to wait to serve it because it already went through the resting stage.

Notes

• If you accidentally cook it longer than you should have and it already has browned do not do the reverse sear.
