Sirloin in a Mushroom Sauce

Sirloin in a Mushroom Sauce

with Caramelized Onion Mashed Potatoes & Roasted Carrots

Our sirloin steak has such a deep, rich, and gloriously meaty flavor that it could be a stand-alone dish with little more than salt and pepper for seasoning. But we’re still adding some top-notch sides and a full-bodied sauce to this recipe so that it soars above and beyond. Ultra-creamy mashed potatoes and tender roasted carrots make it filling and hearty, while the mushroom pan sauce that’s spooned on top has savory complexity.

Instructions

Prep
1

• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Trim, peel, and cut carrots on a diagonal into 1-inch-thick pieces. Peel and dice potatoes into ½-inch pieces. (TIP: For speedier spud prep, skip the peeling.) Halve, peel, and thinly slice onion. Trim and thinly slice mushrooms. Peel and mince garlic.

Cook Carrots & Mash
2

• Toss carrots on a baking sheet with a large drizzle of oil, salt, and pepper. • Roast on top rack until browned and tender, 25-30 minutes. • Meanwhile, place potatoes in a medium pot with enough salted water to cover by 2 inches. Bring to a boil; cook until tender, 15-20 minutes. • Drain and return potatoes to pot. Mash with sour cream until smooth. Season with salt and pepper. • Keep covered off heat until ready to serve.

Caramelize Onion
3

• While potatoes cook, heat a large drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add onion; cook, stirring occasionally, until browned and softened, 8-10 minutes. • Add 1 tsp sugar and a splash of water; cook until caramelized, 2-3 minutes more. Season with salt and pepper. • Turn off heat; transfer to a small bowl. Wipe out pan.

Cook Steak
4

• Pat steak* dry with paper towels; season all over with salt and pepper. • Heat a large drizzle of oil in pan used for onion over medium-high heat. Add steak and cook to desired doneness, 3-6 minutes per side. • Transfer to a cutting board to rest.

Make Sauce
5

• Add 1 TBSP butter and mushrooms to pan used for steak over medium-high heat. Cook, stirring, until softened, 3-5 minutes. • Add garlic; cook until fragrant, 30 seconds. • Stir in demi-glace and ¼ cup water (1⁄3 cup for 4 servings). Bring to a boil, then reduce to a low simmer. • Stir in mustard. Simmer until thickened, 2-3 minutes. Season with salt and pepper.

Finish & Serve
6

• Slice steak against the grain. • Divide mashed potatoes, carrots, and steak between plates. Top mashed potatoes with caramelized onion. Top steak with mushroom sauce and serve.
