Ingredient Checklist


Instructions Checklist
  • Preheat oven to 450 degrees. In a small bowl, stir together mustard, lemon juice, and garlic; season with salt and pepper. Place cup mustard mixture in a resealable plastic bag. Add steaks, and rub to coat (reserve remaining mixture for serving). Let steaks marinate at room temperature 10 minutes, or refrigerate up to 1 day.

  • On a large rimmed baking sheet, toss potatoes with 1 tablespoon oil; season with salt and pepper. Roast 10 minutes, then add asparagus to sheet, and toss with another tablespoon oil. Season with salt and pepper. Roast until potatoes and asparagus are tender, about 15 minutes more.

  • While vegetables are roasting, heat remaining tablespoon oil in a large skillet over high. Remove steaks from marinade, allowing excess to drip off; cook 4 to 5 minutes per side for medium-rare (if pan darkens quickly, reduce heat). Let rest 5 minutes. Serve steaks with vegetables and reserved mustard sauce; garnish with lemon wedges.

Cook's Notes

This no-cook marinade earns a gold star for turning into a multipurpose sauce. Pair it with steak, as we did, or with chicken or pork for equally wow-worthy results.

So easy and so delicious. I used sweet potatoes instead of red potatoes and just added an extra 5 minutes or so of roasting time.

I have made three times already and am making it again tonight as my husband adores it. I doubled the recipe when I made it so I had leftovers and found the marinated steak was delicious over a salad for lunch. My mom loved it so much she asked for the recipe and made it for my brother and his wife. It has become a new favorite of ours!

This was one of the best meals I have made in a long time. The marinade made an incredible dipping sauce for the potatoes and the steak. Nrmally I would skimp and just buy flank steak, but the $12 sirloin was SO worth every penny. I didn;t want the meal to end!
