Cooking Steps

Prep
1

• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Peel and dice potatoes into ½-inch pieces. (TIP: For speedier spud prep, skip the peeling.) Trim green beans if necessary. Halve, peel, and thinly slice onion. Peel and mince garlic.

Cook Potatoes & Beans
2

• Place potatoes in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 15-20 minutes. • Meanwhile, toss green beans on a baking sheet with a large drizzle of oil, salt, and pepper. Roast until browned and tender, 12-15 minutes. • Once potatoes are tender, 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 and green beans cook, heat a large drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add onion and 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 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, 5-7 minutes per side. • Transfer to a cutting board to rest.

Make Sauce
5

• Melt 1 TBSP butter in pan used for steak over medium-high heat. Add garlic and 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 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, green beans, and steak between plates. Top mashed potatoes with caramelized onion. Top steak with demi-glace sauce and serve.
