Bottom sirloin is one of the best loin chops I've been cooking recently.

Its savory flavor and juiciness have earned this cut a spot on my carnivore diet list, so I had to learn more about this cut.

I visited my local butcher to find out where bottom sirloin comes from and talked to my dietitian to determine its nutritional content.

Here's what I found out.

 Quick Summary

  • The bottom sirloin is cut from the sirloin primal, where the top sirloin steak comes from.
  • It's a healthy option for people looking to maintain a healthy weight.
  • The best bottom sirloin steak is one that is well-marbled.

What Is A Bottom Sirloin Steak?

Bottom sirloin steak is a cut of the sirloin primal.

The sirloin primal cut is an area that extends from the spinal column down to roughly the abdominal area above the flank just in front of the hind leg.

It houses the top sirloin or top sirloin butt, bottom sirloin, and tenderloin.

Many sub-primal cuts, such as ball tip sirloin, sirloin tip, tri-tip, and sirloin bavette, are made from the bottom sirloin.

Other names for this sirloin kind include sirloin butt, thick flank, and sirloin roast.

Taste & Texture

The bottom sirloin butt is rated by many as particularly tasty and has a soft and brisket-like texture.

This quality cut of steak has thick marbling throughout, giving it a nearly buttery flavor, although it can become tough if overcooked, just like a top sirloin steak.

Compared to other top sirloin steaks, the sirloin tip roast and ball tip absorb the flavors of a marinade well and will thus soak up those of the 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].

"Steaks can deliver essential nutrients and support your overall wellness when consumed as part of a balanced diet high in vegetables, fruits, and whole grains."

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.
