What is the signature feature of the "Outback Special" steak?

The "Outback Special" steak is best characterized as a seasoned and grilled sirloin steak. This particular preparation highlights the restaurant's focus on delivering quality cuts of beef that are both flavorful and satisfying. The sirloin is known for being a lean and hearty steak, and Outback's method involves seasoning the meat to enhance its natural flavors before grilling it to perfection.

This grilling process is fundamental to the Outback Steakhouse experience, as it imparts a distinctive smoky char while maintaining the juiciness of the steak. The emphasis on seasonings also aligns with the restaurant's dedication to delivering bold flavors that stand out.

In terms of the other options, marinating in teriyaki sauce does not apply to the "Outback Special," as this dish is known for its simple seasoning rather than complex marinades. While filet mignon is a beloved cut of steak, it is not synonymous with the "Outback Special," which specifically features sirloin. Lastly, preparing a steak with garlic butter is more typical of other steak options on the menu rather than being the signature feature of the "Outback Special." Thus, the defining quality of this dish remains its seasoned and grilled sirloin preparation.
