Grilled tarragon and mustard steak is a delicious way to kick off grilling season!


  • One 2 pound flank steak
  • 1/2 cup olive oil
  • 1/2 cup white wine
  • 1/4 cup mustard (Dijon or grainy Dijon mustard work really well for this)
  • 3 scallions, chopped
  • 3 tablespoons chopped fresh tarragon, plus extra for garnish
  • Coarse salt and fresh ground pepper


  1. Combine oil, wine, mustard, scallions and chopped tarragon in a zipper plastic bag. Add steak, seal bag and rotate until steak is coated. Marinate in refrigerator for 2 hours and up to overnight, turning the bag over occasionally.
  2. Heat grill to high. Discard marinade and grill steak for 5 minutes per side for medium rare.
  3. Rest steak under foil for 10 minutes (don’t skip this step, I beg of you) and then slice against the grain into thin slices. Serve at once.
