This tender, flavourful Herb Mustard Crusted Roast Beef recipe is a delicious option for Sunday dinner, entertaining or a special holiday meal.



  • 1.5 kg or 3 lb beef roast (top sirloin, eye of round roast)
  • 2 tbsp avocado oil
  • Himalayan or sea salt + freshly ground pepper
  • 1/2 cup finely chopped parsley
  • 3 tbsp finely chopped oregano
  • 3 tbsp finely chopped thyme
  • 3 tbsp finely chopped rosemary
  • 3 cloves garlic, minced
  • 1/4 cup hot mustard (i.e. Dijon or German mustard)
  • Optional (but highly recommended): Creamy Herb Sauce

Equipment Needed:


  1. Preheat oven to 350F / 180C.
  2. Heat avocado oil in a cast iron pan over medium-high heat.  Pat roast dry with some paper towel, season well with salt and pepper and place in pan to sear on all sides until golden brown (approx. 2-3 min per side).
  3. Place the cast iron pan containing the roast into the oven for 20 minutes.
  4. Meanwhile, mix together the parsley, oregano, thyme, rosemary, garlic and mustard in a small bowl.  
  5. After 20 minutes, remove the pan from the oven and spread the herb mustard mixture onto the top and sides of the roast.
  6. Return the roast to the oven and cook to desired degree of doneness.  For medium rare, pull out of the oven when meat thermometer reads 125F (approx. another 25-30 min) or 135F for medium.  (Note: these temperatures are 5F below desired doneness since temperature will continue to rise a bit while resting).
  7. Transfer roast to a cutting board and tent loosely with foil.  Allow to rest for 10 minutes before slicing.
  8. Serve with this Creamy Herb Sauce and enjoy! 


  • Let roast come to room temperature before cooking.  Remove from fridge 45-60 min before cooking.
