Servings: 6 servings

Equipment

  • large bowl
  • roasting pan

Ingredients

  • 12 small potatoes halved or quartered
  • 12 Brussels sprouts cut in half
  • 3 small onions coarsely chopped
  • 3 carrots peeled & quartered
  • 6 garlic cloves peeled
  • olive oil
  • salt & pepper to taste
  • 3 pounds rump roast
  • 3 sprigs fresh rosemary

Instructions

Prepare the Roast

  • Remove the rump roast from the refrigerator at least 1 hour before cooking to bring it close to room temperature. This ensures even cooking.
  • Pat the roast dry with paper towels. Moisture on the surface prevents browning.
  • Generously season all sides with salt and pepper.
    Optional tip: Make small slits in the meat and insert garlic slivers for extra flavor.

Prep the Vegetables

  • About 15 minutes before roasting, preheat your oven to 450°F (232°C).
  • In a large bowl, toss potatoes, Brussels sprouts, onions, carrots, and garlic with olive oil, salt, and pepper until evenly coated.
    Optional tip: Use your hands for better coating and a little fun in the kitchen.

Arrange Roast & Vegetables

  • Place the roast fatty side up in a roasting pan. A pan large enough for both meat and vegetables is ideal.
  • If your pan is small, split the vegetables between two pans.
    Optional tip: For even air circulation, you can place the roast directly on the oven rack with a pan below to catch drippings, but cleaning is easier with a pan.
  • Nestle the vegetables around the roast.
  • Insert a meat thermometer into the thickest part of the roast.
  • Lay sprigs of rosemary on and around the meat.

Intial High-Heat

  • Roast at 450°F (232°C) for 20 minutes to create a caramelized crust on the beef.
    Tip: This step locks in juices and develops flavor.

Lower Heat & Continue Roasting

  • Reduce oven temperature to 300°F (149°C).
  • Continue roasting until the meat reaches your desired doneness:
    Medium rare: 135°F (57°C)
    Medium: 145°F (63°C)
    Well done: 160°F (71°C)
    Cooking time varies based on roast size, oven type, and vegetable quantity. Use the thermometer, not just time, for accuracy.

Manage Vegetables & Resting Meat

  • If meat is done but vegetables need more time: Remove roast, loosely cover with foil, and return vegetables to oven until tender.
  • If vegetables are done but meat is still cooking: Transfer vegetables to a bowl and cover, then continue roasting the meat.
  • Rest roast 5–10 minutes under foil before slicing. This allows juices to redistribute.

Serve

  • Slice roast thinly against the grain.
  • Plate with roasted vegetables and enjoy a perfectly balanced meal.

Notes

Extra Tips:

For more flavor, toss vegetables with a teaspoon of fresh herbs or garlic powder.
Turn vegetables halfway through roasting for even caramelization.
Reserve pan drippings for a simple gravy.
