Instructions:
Roast Beef
The roast will marinate 24 to 48 hours before cooking. Prepare the marinade by combining garlic, red pepper flakes, lemon zest & juice, thyme, rosemary, olive oil, salt & pepper in a bowl. Mix marinade together until well combined. Remove the rump roast from packaging & pat dry. Rub marinade over all sides of the roast. Cover in plastic wrap & transfer to the fridge.
Remove roast from the refrigerator 1 hour before cooking, allowing it to come to room temperature. Preheat oven to 200º. Place roast on a wire rack set inside of a rimmed baking sheet. Cook until a thermometer inserted into the center reads 125º, approximately 3-4 hours. Remove from the oven & allow to rest at room temperature for 45 minutes to an hour before carving as thinly as possible. Serve with buns, pickled onions, horseradish mayonnaise & lettuce.
Pickled Onions
Put sliced onions in a ball jar & set aside. Place vinegar, water, sugar & salt in a small sauce pan & bring to a boil. Stir to dissolve the sugar & salt. Remove from heat & pour pickling mixture over the onions. Allow to sit at room temperature for at least 30 minutes before serving. Store in the fridge if not using that same day.
