What Is A Bottom Sirloin Steak?

Bottom sirloin steak comes from the sirloin primal, a large area extending from the spinal column down toward the abdominal region, just above the flank and in front of the hind leg. This primal is divided into three main sub-primals: top sirloin (or top sirloin butt), bottom sirloin, and tenderloin.
From the bottom sirloin specifically, several popular sub-primal cuts are derived, including ball tip sirloin, sirloin tip, tri-tip, and sirloin bavette.
Common alternative names for this cut include sirloin butt, thick flank, and sirloin roast.

Taste & Texture
The bottom sirloin butt is widely regarded for its excellent flavor and a tender, brisket-like texture. This quality cut of steak features thick marbling that contributes a nearly buttery richness, though it can become tough if overcooked — much like top sirloin. Unlike top sirloin, bottom sirloin cuts such as the sirloin tip roast and ball tip excel at absorbing marinades, making them especially receptive to bold flavors from your ingredients.
Is Bottom Sirloin Steak Healthy?

Yes, bottom sirloin steak is healthy.
Like the top sirloin steak, bottom sirloin steak is a fantastic source of protein and is stuffed with B vitamins and minerals for a robust immune system [1].
It's one of the healthiest sirloin steak selections because it is low in fat.
The leanness of this sirloin can also be advantageous for those trying to eat less cholesterol and saturated fat to maintain a healthy weight and lower their cardiovascular health risks [2].
The high iron content of bottom sirloin steak also aids in producing red blood cells and oxygen distribution throughout the body [3].

What To Look For When Choosing A Bottom Sirloin?

When choosing a bottom sirloin, you should look for a cut with a decent amount of marbling.
When cooking, the fat melts, giving the beef a rich and delicious flavor.
The melting marble fats softly baste the sirloin inwardly as they warm up during cooking, adding marbled beef tenderness.
Steak thickness is another factor that you should consider.
Look for 1.5 inches of bottom sirloin steaks to make it easier to achieve that desired contrast between the interior and exterior of a bottom sirloin steak.
What's The Best Way To Cook Bottom Sirloin?
Like most top sirloin steaks, the best way to cook bottom sirloin is on the stovetop, grill, or oven by roasting or barbecuing.
It will take roughly 40-45 minutes to cook thoroughly when roasted or broiled.
Depending on your desired doneness, each side should be seared after cooking on the grill or stovetop for 10-15 minutes.
I recommend that you only turn over the sirloin once, not repeatedly.
Always let your steak rest for 5-10 minutes, whether a top sirloin steak or a sirloin tip roast.

Rewrap the meat in plastic and ensure there is no air between the sirloin and the wrapping.
