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


  • 3 pounds (1.5 kg) beef roast (top sirloin, eye of round roast)
  • 2 tablespoons avocado oil
  • Himalayan or sea salt + freshly ground pepper
  • 1/2 cup finely chopped parsley
  • 3 tablespoons finely chopped oregano
  • 3 tablespoons finely chopped thyme
  • 3 tablespoons 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: Preheat oven to 350F / 180C.
  2. Sear roast: 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. Roast in oven: Place the cast iron pan containing the roast into the oven for 20 minutes.
  4. Mix topping: Meanwhile, mix together the parsley, oregano, thyme, rosemary, garlic and mustard in a small bowl.  
  5. Spread on topping: After 20 minutes, remove the pan from the oven and spread the herb mustard mixture onto the top and sides of the roast.
  6. Continue roasting: 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. Rest: Transfer roast to a cutting board and tent loosely with foil.  Allow to rest for 10 minutes before slicing.
  8. Serve: Serve with this Creamy Herb Sauce and enjoy! 


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