Ingredients:
1 pound boneless New York strip steak, patted dryKosher salt, freshly ground pepper
5 garlic cloves, 1 minced, 4 thinly sliced
⅓ cup Dijon mustard
1 tablespoon sherry vinegar or red wine vinegar
1 teaspoon honey
1–2 pinches cayenne pepper
⅓ cup plus 3 tablespoons olive oil
1 bunch scallions, thinly sliced
1 10-ounce bag frozen peas
1 bunch asparagus, trimmed, cut into 1-inch pieces
Preparation:
Season steak all over with salt and pepper. Whisk grated garlic, mustard, vinegar, honey, cayenne, ⅓ cup oil, and 1 Tbsp. water in a medium bowl to combine; season spicy mustard with salt and pepper.Heat a dry medium skillet, preferably cast iron, over medium-high. Rub steak all over with 1 Tbsp. oil and cook, turning every 2 minutes or so and making sure to get color on the fat cap, until medium-rare (an instant-read thermometer inserted into the center will register 120°), about 10-15 minutes. Transfer steak to a plate to rest. Pour off oil from skillet, leaving crispy bits behind.
Heat remaining 2 Tbsp. oil in same skillet over low. Add sliced garlic and scallions and cook, stirring often, until translucent and softened, about 3 minutes. Add peas and a splash of water and cook, stirring and mashing to break up slightly, until peas are tender, about 5 minutes. Add asparagus along with a few tablespoonfuls of mustard sauce; season with salt and pepper. Cook, stirring often, until asparagus is just tender, about 5 minutes. Remove from heat.
Slice steak and shingle over vegetables in skillet. Drizzle some mustard sauce over steak. Serve with remaining mustard sauce alongside.
