Rump Roast
Rump roast is a beef roast cut from the rear corner of the round primal where the round meets the sirloin. It is more flavorful than top round but slightly tougher because of more developed connective tissue. The traditional preparation is pot-roasting or braising; modern slow-cooking and sous-vide methods make excellent medium-rare slicing roasts from it as well.

The traditional preparation is pot-roasting or braising; modern slow-cooking and sous-vide methods make excellent medium-rare slicing roasts from it as well.
The rump section sits at the boundary between the sirloin and the round, and the cut takes muscle from both primals depending on local butchery. US rump roast is bottom round near the sirloin junction; UK silverside includes a similar region. The cut has more connective tissue than top round but more flavor, which is why pot-roasting (slow moist heat) is the historical preparation, the connective tissue dissolves into gelatin and the lean stays moist.
For modern slow-cook preparations, rump roast holds up very well at low temperatures: 110°C / 225°F oven or sous-vide at 56°C / 133°F for 12 hours produces a medium-rare slicing roast with the connective tissue partially broken down. The leftover fat and tendon-like seams should be trimmed before slicing.
Also known as: Bottom round rump, Standing rump roast, Round tip roast, Silverside (UK, partial).
What good quality looks like
- A wedge-shaped or rounded roast, denser than top round
- Visible connective-tissue seams running through, more than top round
- Bright deep-red lean color
- A thin to moderate fat cap on one face
- Some surface marbling, less than loin cuts but more than eye of round
How to cook it
- Pot-roast: braise in liquid at 95-110°C / 200-225°F for 3 to 4 hours until fork-tender
- Slow-roast for slicing: 110°C / 225°F oven to internal 54°C / 130°F, rest, slice thin against the grain
- Sous-vide: 56°C / 133°F for 12 hours, then high-heat sear
- Trim heavy connective-tissue seams before slicing; they will not break down at slicing temperatures
Frequently asked
What is the difference between rump roast and top round?
Both are in the round primal. Top round is the inner thigh, more uniform and slightly more tender. Rump roast comes from the rear corner where the round meets the sirloin, more flavorful but with more connective tissue running through. Top round prefers fast roasting; rump roast prefers slow.
Can rump roast be cooked medium-rare?
Yes, with the right method. Sous-vide at 56°C / 133°F for 12 hours, or a low oven at 110°C / 225°F to internal 54°C / 130°F. Both methods let the connective tissue partially break down without overcooking the lean. Faster cooking methods leave the connective tissue tough.
Is rump roast the same as silverside?
Roughly. UK silverside includes the rump section plus surrounding bottom-round muscle, sold for traditional slow-cooked roasts. Names and exact break-points vary by region, but the eating quality and cooking approach is similar.
How can I tell if a rump roast is high quality from a photo?
Look for a clean wedge shape, bright deep-red lean, fine evenly-distributed connective-tissue seams (rather than thick chunky seams), and a moderate fat cap. Heavy connective-tissue patches signal older animals or lower grades.
