Sirloin Steak with Roasted Brussels, Potatoes, and Mushroom Pan Sauce
This is the richer option of the set: a steakhouse-style dinner built around beef top sirloin, roasted Brussels sprouts, and a warm mushroom-pan sauce with crisp-edged potatoes. It costs more and feels more indulgent than the others, but still fits into an under-an-hour evening and plates beautifully for a date-night-at-home feel.

- Brussels Sprouts 12 ounces, trimmed and halved 3.99
- Organic Yellow Potato 12 ounces, cut into 3/4-inch pieces 2.59
- 365 Mushroom Baby Bella Slcd 8Oz Cv 1 package 2.99
- Organic Shallots 1 small shallot, thinly sliced 4.99
- Lemon 1/2 lemon, for finishing vegetables 0.99
- Organic Thyme, 0.5 OZ 1 teaspoon leaves 2.99
- Pantry items 1 1/2 tablespoons olive oil, 1 tablespoon butter, salt, black pepper, 1/3 cup water or stock, 1 teaspoon Dijon mustard optional
Instructions
- Preheat the oven to 425°F. Take out 1 beef top sirloin steak, 12 ounces, and let it sit at room temperature for 15 minutes while you prep the vegetables.
- Trim and halve 12 ounces Brussels sprouts. Cut 12 ounces organic yellow potato into 3/4-inch pieces. On a sheet pan, toss the 12 ounces Brussels sprouts and 12 ounces potatoes with 1 tablespoon olive oil, salt, black pepper, and 1 teaspoon thyme leaves.
- Roast the vegetables at 425°F for 25 to 30 minutes, turning once halfway through, until the potatoes are browned at the edges and the Brussels sprouts are deeply caramelized with some crisp outer leaves.
- While the vegetables roast, pat the 12-ounce beef top sirloin steak dry very well. Season both sides generously with salt and black pepper.
- Heat a heavy skillet over medium-high heat on the stove. Add 1 teaspoon olive oil. Sear the 12-ounce steak for about 4 to 5 minutes on the first side and 3 to 4 minutes on the second side for medium-rare to medium, depending on thickness. Add 1 tablespoon butter in the last minute and baste briefly if you like.
- Transfer the steak to a cutting board and rest it for 8 minutes so the juices settle.
- Reduce the skillet heat to medium. Add 1 thinly sliced small shallot and the 1 package sliced baby bella mushrooms to the same pan. Cook for 4 to 5 minutes until the mushrooms brown and the shallot softens.
- Add 1/3 cup water or stock and 1 teaspoon Dijon mustard if using. Scrape up the browned bits and simmer for 1 to 2 minutes until lightly reduced into a glossy pan sauce. Taste and adjust with salt and black pepper.
- When the vegetables come out of the oven, squeeze over the juice from 1/2 lemon to brighten them. Toss gently so the sprouts stay intact and glossy.
- Slice the rested 12-ounce steak across the grain into neat strips. For plating, spoon the roasted potatoes slightly off-center on each plate, nestle the Brussels sprouts beside them, and fan the steak slices over part of the potatoes. Spoon the mushroom-shallot sauce over the steak, leaving some crust visible for a restaurant-style presentation.
- Serve immediately. Cabernet Sauvignon or Syrah are excellent with the beef and mushroom sauce.
