Sirloin Roast with Mustard Rub

Searing a large piece of beef and then roasting it in the oven gives you the best of two worlds: crisp, caramelized edges and a tender, juicy interior. Our herb-laced Dijon rub is the icing on this sirloin roast.

Ingredients

  • 3 lb sirloin roast beef, trimmed of visible fat
  • 3 tbsp olive oil, divided
  • 1/4 tsp each sea salt and fresh ground black pepper, plus additional to taste
  • 4 cloves garlic, chopped
  • 1/4 cup Dijon mustard
  • 1 tbsp chopped flat-leaf parsley
  • 1 tbsp chopped fresh rosemary
  • 1 tbsp chopped fresh sage
  • Juice 1/2 lemon

Preparation

  1. Preheat oven to 325˚F.
  2. With paper towel, pat beef dry. Rub 1 tbsp oil over both sides of beef and season with salt and pepper.
  3. Prepare Mustard Rub: In a small bowl, combine garlic, Dijon, parsley, rosemary and sage. Stir to combine and add lemon juice, 1 tbsp oil and pepper, to taste.
  4. In a cast iron skillet, heat remaining 1 tbsp oil on medium-high. Add beef and sear on all sides until browned, 2 to 3 minutes per side. Remove from heat, place on a cutting board and brush Mustard Rub over top and sides of roast. Return to skillet and transfer to oven for about 20 minutes per lb (1 hour total for a 3 lb roast). (Alternatively, cook until an instant-read thermometer registers 145 F for medium-rare, 160 F for medium or 170 F for well done when inserted into center of beef). Remove from oven, cover loosely with foil and let rest for about 10 minutes. Remove strings and serve.
