Ingredients
Instructions
- Place the beef rump roast in a roasting pan and bake at 375°F for 1 hour.
- Arrange peeled potatoes and halved carrots around the roast in the pan.
- Combine the cream of mushroom soup, salt, cornstarch, sugar, and one can of water in a blender and process until smooth.

Tips & Substitutions
For a more flavorful roast, consider marinating the beef overnight in your favorite seasonings. If you don't have cream of mushroom soup, a homemade blend of sautéed mushrooms and heavy cream can work well. For added texture, you can use parsnips or sweet potatoes instead of regular potatoes. Be sure to check the roast's internal temperature for doneness, aiming for 135°F for medium-rare.
Serving Suggestions
Serve Lu's Roast Beef with a side of crusty bread to soak up the delicious sauce. A fresh green salad or steamed green beans can add a nice contrast to the rich flavors of the dish. This roast pairs beautifully with Mushroom Wild Rice for a hearty meal, making it perfect for family gatherings or special occasions.
Storage & Reheating
Leftover roast beef can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, slice the roast and warm it gently in a skillet over low heat, adding a splash of beef broth to keep it moist. You can also microwave it covered with a damp paper towel, but be careful not to overheat to avoid drying it out.

Frequently Asked Questions
Can I use a different cut of beef for this recipe?
Yes, while a rump roast is ideal for slow cooking, you can substitute it with chuck roast or brisket. Just remember that cooking times may vary depending on the cut, and always check for tenderness before serving.
How do I know when the roast is done?
The best way to check the doneness is with a meat thermometer. For medium-rare, aim for an internal temperature of 135°F. If you prefer medium or well-done, adjust accordingly, allowing for an extra hour in the oven if needed.
Can I prepare this dish in advance?
Absolutely! You can prepare the roast and vegetables a day ahead, refrigerate them, and then bake them when you're ready. Just be sure to allow extra time for reheating, and check that the internal temperature reaches a safe level before serving.
