  • 2 rosemary stalks removed, only leaves, sprigs
  • 4 cloves garlic
  • 1 tbsp kosher salt
  • 1.5 tbsp black pepper coarsely cracked
  • 2 - 3 tbsp vegetable oil
  • 2.5 lbs beef roast chuck or rump roast, or sirloin top roast, or eye of round roast
Mustard Butter
  • 2 tbsp dijonnaise
  • 4 tbsp butter unsalted
  • salt to taste
Steak Sandwiches (For Two)

  • 3 tbsp mustard butter
  • beef thinly sliced, slow roasted
  • 1/4 cup peach relish or more
  • onion caramelized
  • 2 - 3 tbsp mayonnaise

Instructions

Slow Roasted Beef Roast
    Cup of Yum
  1. Preheat oven to 200°F. Line a baking tray with foil and place a baking rack (roast rack) on top.
  2. Place the rosemary, garlic and oil in a small food processor. Process until you have a paste.
  3. Mix the rosemary-garlic paste with the salt and pepper. Spread half of this spice paste over the beef roast.
  4. Heat a cast iron pan to medium-high heat. Coat the bottom of the pan with vegetable oil and allow it to heat up. When the oil is hot, sear the beef roast in the pan, 3 - 4 minutes per side, until you form a caramelized crust.
  5. Place the seared cut of roast on the roast rack and spread the other half of the spice paste on the roast.
  6. Insert the meat thermometer into the roast, and place it in the preheated oven. Set the temperature to the required done-ness (133°F - rare, 138°F - medium, 145°F - medium to well-done), and slow roast the beef until the meat reaches the right temperature (mine took 2 hr 45 minutes for a 134°F internal temperature).
  7. When the roast is cooked through, remove it from the oven and let it rest for about 20 - 30 minutes.
  8. OPTIONAL STEP to smoke the roast - place the slow roasted beef in an airtight, glass container. Using a hand-held smoker, create smoke with hickory wood chips. Fill the container with the smoke and close it immediately. Allow the smoke to infuse with the roast, until the smoke disappears. Repeat this process 2 - 3 more times, to add a delightful smokiness to  your roast.
  9. When ready to serve, slice very thinly and serve.
Mustard Butter
  1. Mix the dijonnaise and butter until you have a smooth paste. Add salt to taste. Set aside until needed.
Steak Sandwiches (For Two)
  1. Spread the mustard butter on the lower half of the toasted buns.
  2. Top with thinly sliced slow roasted beef, followed by the caramelized onions and peach relish.
  3. Layer the salad leaves on top. Spread mayonnaise on the top half of the bread bun and serve with potato chips.
