When shopping for this recipe, quality matters—especially for the steak. Look for well-marbled sirloin with good color, as this will guarantee tenderness and flavor. For the wine component, don’t worry about using anything fancy; a medium-bodied red you enjoy drinking works perfectly. And while the recipe specifies red and yellow onions, you can certainly adjust based on what’s available. The different onion varieties create lovely visual contrast and subtle flavor differences, but if you only have one type on hand, that’ll work just fine in a pinch.
How to Make these Steakhouse Sirloin & Onions
The magic of this steakhouse classic starts with a flavorful rub for your 1½ pounds of sirloin steak. Combine 1 tablespoon olive oil with 1½ teaspoons dried onion flakes, ¾ teaspoon of garlic powder (you’ll use the rest later), ½ teaspoon dried rosemary, ½ teaspoon salt, and ¼ teaspoon pepper. This aromatic mixture gets brushed generously over one side of your thick-cut steak. No need to marinate—this instant flavor boost works its wonders during cooking.
For cooking, you’ve got options. Position your broiler rack about 4 inches from the heat source, or fire up the grill if you prefer those classic grill marks. Place your seasoned steak on the cooking surface with the seasoned side facing up, and let it cook undisturbed for 12-15 minutes for medium-rare doneness under the broiler (or cook to your preferred doneness on the grill). A premium meat thermometer ensures perfect temperature control for restaurant-quality results every time.
Meanwhile, the onion sauce—truly the crown jewel of this dish—comes together in a separate pan. Melt 1 tablespoon of butter in a large skillet over medium-high heat, then add your red and yellow onion wedges along with the chopped shallot. Cover and cook for about 5 minutes until they begin to soften, stirring occasionally.
Then uncover and continue cooking until they develop a beautiful light brown color, about 5 more minutes.
The final touch involves creating that restaurant-quality sauce. Once your onions have caramelized, stir in the remaining garlic powder, rosemary, salt and pepper. The ½ cup of red wine and ¼ cup of chicken broth go in next, creating a simmering bath that reduces by half over the next 5-10 minutes, concentrating all those incredible flavors.
Just before serving, swirl in the remaining tablespoon of butter to add silky richness to your sauce. If you enjoy creating culinary masterpieces like this, you might consider adding a pasta maker appliance to your kitchen collection for more homemade meal options. Slice your perfectly cooked sirloin against the grain, arrange it over a bed of mashed potatoes, and spoon that luxurious onion sauce generously over the top. The combination of tender beef, sweet caramelized onions, and the rich wine reduction? That’s what steakhouse dreams are made of.
Steakhouse Sirloin & Onions Substitutions and Variations
While this classic sirloin and onions recipe is delicious as written, you’ve got plenty of room to play with substitutions that won’t compromise the dish’s soul.

The onion varieties are flexible too—sweet Vidalia onions create a more mellow flavor profile.
And don’t feel tied to mashed potatoes; this savory steak and onion combo pairs beautifully with roasted potatoes or creamy polenta.
