Ontario has been cattle country since the 1800s, and the province’s beef farmers still raise some of the finest cattle in Canada, from the rolling hills of Grey County to the pastures of Wellington. The Sunday roast was the centrepiece of Ontario home cooking for generations — a big piece of beef, a hot oven, and a table full of family, with leftovers stretched into Monday’s sandwiches. It’s the meal that taught a whole province how to cook, and it still anchors holiday tables and special Sundays today.

What makes it great is the ritual as much as the flavour: the garlic-rosemary crust, the perfect rosy centre, and the rich brown gravy made from the pan drippings. Slice it thin, pile it on a platter, and let everyone help themselves — with roasted potatoes, Yorkshire pudding, and a big dish of gravy alongside. It’s simple, impressive, and tastes like the best kind of home cooking.

Step by stepInstructions

  1. Take the roast out of the fridge an hour before cooking and pat it dry with paper towels.
  2. Cut small slits all over the roast and tuck the garlic slivers into them.
  3. Rub the roast all over with olive oil, then coat it with the rosemary, thyme, salt, and pepper.
  4. Sear the roast in a hot, oven-safe skillet on all sides until deeply browned, about 3 minutes per side.
  5. Roast at 375°F until the internal temperature reaches 130°F for medium-rare, about 20 minutes per pound.
  6. Transfer the roast to a cutting board, tent it loosely with foil, and let it rest for at least 15 minutes before carving.
  7. Set the skillet over medium heat, whisk in the flour, then pour in the beef broth and wine if using, scraping up the browned bits and simmering until the gravy thickens.
  8. Slice the roast thinly against the grain and serve with the hot gravy.

💡 Chef tips & storage

Resting is not optional — it lets the juices redistribute so every slice stays moist. Use a meat thermometer for a perfect centre every time: 130°F for medium-rare, 145°F for medium. Leftover roast beef makes the best sandwiches, sliced thin with horseradish.
