Ingredients

  • 4-6 pounds sirloin roast top sirloin or sirloin tip
Seasoning
  • 1/2 cup butter softened
  • 2 teaspoons dried rosemary
  • 2 teaspoons minced garlic 
  • 1 teaspoon flaked sea salt
  • 1/2 teaspoon dried thyme
  • 1.4 teaspoon ground pepper
Vegetables
  • 6-8 cups of carrots/potatoes/onions cut into large chunks you can make more in a large roaster if you are feeding more people

Instructions

    Cup of Yum
  1. Remove your roast from all its packaging and let it sit out for an hour until it’s about room temperature.
  2. Pre-heat your oven to 450.
  3. Mix the butter and seasoning together until combined.
  4. Cover the top of the roast in the butter mixture.
  5. Place the vegetables in the bottom of the roaster.
  6. Place the roast in the center of the vegetables.
  7. Place in the oven - without the lid! - and cook for 15-20 minutes, until the top of the roast is seared and brown.
  8. Turn the oven temperature down to 325 and place the lid on the roaster.
  9. Cook to 10 degrees BEFORE your desired temperature - 120-140 - see my chart in the post. Your roast will continue cooking after you pull it out of the oven.
  10. Remove and set on stove for 20 minutes, keeping the lid on and the roaster sealed ( instead of tenting with tinfoil.)

Notes
