Cooking your roast beef low and slow eliminates the possibility of that gray, discoloured meat around the edges and ensures that your meat is cooked to your desired temperature from edge to edge.

Ingredients

Servings:
6
  • 3–4 lb (1.4–1.8 kg) top sirloin roast, aka spoon roast (or another roast cut of choice)
  • 2 TBSP (30 ml) olive oil
  • 8 garlic cloves
  • 1 heaping tsp (6 g) kosher salt
  • 1/2 tsp (2.5 g) freshly ground black pepper
  • 1/2 tsp (1.5 g) paprika
  • 1/2 tsp (1.5 g) onion powder
  • 1/4 tsp (0.5 g) garlic powder
  • 1/4 tsp (0.3 g) thyme
  • 1/8 tsp (0.3 g) oregano
  • 1/8 tsp (0.3 g) chili powder
  • 1 1/2 TBSP (15 g) cornstarch
  • 1/4 cup (60 ml) cold water
  • 1 1/2 cups (360 ml) beef broth
  • 1 TBSP (14 g) butter
  • Salt to taste

Instructions

  1. 1

    Remove the roast from the fridge at least an hour before roasting. Pat it dry with paper towels. Rub with olive oil and season with your seasoning mix. Make small cuts in the meat and insert the garlic cloves into the incisions. Ideally, refrigerate the roast covered overnight—this will allow those flavours to absorb into the meat. But you can proceed to the next step immediately, if desired.

  2. 2

    Preheat the oven to 425°F (220°C). Place racks inside your roasting pan. Place the roast on top of the racks, fatty side up. Bake in the preheated oven, uncovered, for 15 minutes—this will nicely brown the beef. Then reduce the oven temperature to 225°F (107°C) to roast low and slow.

  3. 3

    I don't go by the suggested cooking time but rather rely heavily on internal thermometers for accuracy. For a 3-lb (1.4 kg) roast, I find the average cooking time is about 1.5 hours, but it really depends on the shape of the roast. The roast in the pictures is taken out of the oven at 140°F (60°C). I would suggest taking the roast out between 135°F (57°C) and 145°F (63°C), depending on preference (135°F is considered medium-rare, while 145°F is considered medium). Remove the roast from the oven and from the roasting pan, cover loosely with foil, and allow it to rest for 15 minutes. It's very important to allow the meat to rest!

  4. 4

    In the meantime, set the roasting pan over medium heat. Add the stock and cook, scraping the bottom of the roasting pan until slightly reduced. Make a cornstarch slurry by mixing cornstarch with water, and add it to the pan while stirring. Cook until the gravy thickens slightly. Add the spices. Taste and adjust the seasoning. Strain into a serving bowl. Add the butter and stir vigorously.

  5. 5

    Slice the beef thinly and serve with the gravy. Enjoy!

FAQ

Can you make this roast beef ahead of time?+
Yes! Season and insert the garlic cloves, then refrigerate covered overnight for the flavors to fully absorb into the meat—this actually makes it taste better. You can also roast it a day ahead and reheat it gently in a 300°F oven until warmed through.
What should the internal temperature be for roast beef?+
For a top sirloin roast, aim for 130-135°F for medium-rare, which stays juicy and tender. Use a meat thermometer inserted into the thickest part, and remember the temperature will rise 5 degrees while resting, so pull it out a few degrees early.
Can you substitute the top sirloin roast with a different cut?+
Absolutely—chuck roast, ribeye, or beef tenderloin all work great with this seasoning and method. Just adjust cooking time based on the cut's thickness and tenderness; leaner cuts like sirloin need less time than fattier cuts like chuck.
Why is my roast beef tough instead of tender?+
The most common mistake is not letting it rest at room temperature for an hour before roasting, or overcooking it past medium-rare—both cause the meat to toughen up. Always let it rest for 10-15 minutes after roasting before slicing, which keeps the juices locked in.
