Sirloin Steak with Mushroom Pan Sauce, Smashed Potatoes & Roasted Asparagus
This is the richer, more special-occasion option: seared sirloin steak with a warm mushroom and red wine-style pan sauce, plus crisp-edged roasted asparagus and buttery smashed potatoes. It’s steakhouse comfort scaled for a family weeknight, but still under an hour and beautifully plated.

Instructions
- Heat the oven to 425°F. Place 1 lb scrubbed Yukon Gold potatoes in a saucepan, cover with cold salted water, and bring to a boil. Simmer 15 to 18 minutes until fork-tender.
- While the potatoes cook, toss 1 lb trimmed asparagus with 1 tablespoon olive oil, 1/4 teaspoon kosher salt, and 1/4 teaspoon black pepper on a sheet pan. Set aside.
- Pat the 1 lb top sirloin steak very dry. Season all over with 3/4 teaspoon kosher salt and 1/2 teaspoon black pepper. Let it sit at room temperature while you prep the rest.
- In a bowl, combine 8 oz sliced mushrooms, 1/2 lb sliced white onion, and 2 minced garlic cloves so they’re ready for the skillet. In a measuring cup, combine 1/2 cup beef broth, 1 teaspoon Worcestershire sauce, and 1 teaspoon Dijon. Add 1/3 cup dry red wine if using.
- Drain the potatoes well and spread them on a second lightly oiled sheet pan or one side of the asparagus pan if there is room. Gently smash each potato with the bottom of a mug or measuring cup. Dot with 1 tablespoon butter, drizzle with 1/2 tablespoon olive oil, and season with 1/4 teaspoon salt and a pinch of pepper.
- Roast the smashed potatoes and asparagus for 18 to 22 minutes, removing the asparagus earlier if it is tender at 12 to 15 minutes. Finish the asparagus with a squeeze of juice from 1/2 lemon.
- While the vegetables roast, heat a heavy skillet over medium-high heat and add the remaining 1/2 tablespoon olive oil. Sear the sirloin steak for about 3 to 4 minutes on the first side and 3 to 4 minutes on the second side for medium-rare to medium, depending on thickness. Transfer the steak to a board to rest for at least 8 minutes.
- Reduce the skillet heat to medium. Add 1 tablespoon butter, then the mushrooms and onions. Cook for 6 to 8 minutes, stirring occasionally, until the onions are soft and the mushrooms are browned and have given off their moisture.
- Add the garlic mixture if not already included, then pour in the broth mixture and the 1/3 cup red wine if using. Scrape up the browned bits and simmer for 2 to 4 minutes until lightly reduced and glossy. Swirl in the remaining 1 tablespoon butter.
- Slice the rested steak against the grain. Taste the mushroom pan sauce and adjust seasoning if needed.
- Plate restaurant-style by shingling slices of steak across each plate, leaning them slightly. Spoon the mushroom-onion sauce over part of the steak. Add a neat pile of smashed potatoes and a bundle of asparagus to the side for height and color contrast. Finish with parsley or chives if using.
