We seasoned it with salt and pepper and threw it in a hot pan. What came out was one of the most tender steaks we’ve ever had. Twice-cooked potatoes and crunchy flat leaf spinach transform what was a meat and potatoes plate into a modern weeknight supper. Cook, relax and enjoy!

What you’ll need: 1 lb fingerling potatoes
2 scallions
2 Tbsp red wine vinegar
2 tsp prepared horseradish
1 tsp Dijon mustard
2, 7 oz sirloin filet steaks
flat leaf spinach
coarse salt
olive oil
freshly ground black pepper

Equipment: medium pot
rimmed baking sheet
large skillet

Recipe steps: 1. Boil potatoes
Preheat oven to 450°F. Place potatoes and 1 tablespoon salt in a medium pot and add cold water to cover by 1 inch. Bring to a boil and cook until potatoes are tender, 15–18 minutes; drain and return to pot to dry.

2. Make dressing
   Trim roots from scallions and thinly slice. Place in a large bowl and whisk in vinegar, horseradish, Dijon, 2 tablespoons oil and ¼ teaspoon salt; season with pepper.

3. Roast potatoes
   Coat a rimmed baking sheet with 2 tablespoons oil. Add potatoes, ½ teaspoon salt and toss to combine. Using the bottom of a glass, press down on each potato to flatten slightly, then turn to coat in oil. Roast until golden and crispy, 15 minutes.

4. Cook steak
   Heat 2 teaspoons oil in a large skillet over medium-high. Season steak with 1 teaspoon salt and lots of pepper. Cook, turning once, until deeply browned, 3–4 minutes per side. Transfer steak to a board to rest and remove skillet from heat.

5. Warm vinaigrette
   Add vinaigrette to hot skillet and stir, scraping up any browned bits from bottom of skillet, until evenly incorporated.

6. Serve
   Divide steak, potatoes and spinach between plates and drizzle warm vinaigrette over everything. Enjoy!
