Date night just got 100 times easier, and 100 more impressive. Flavorful flank steak gets a quick nap in some umami-packed marinade, then a quick sear to perfection in a hot pan. In the same pan, you can make a delicious sauce for the top, with mushrooms, a little wine, and garlic. With this shockingly simple steak preparation and an even easier mushroom sauce, this recipe will deliver all of the flavors, with way less time in the kitchen.

Cooking Instructions

Hide images
step 1
In a small bowl, combine Honey (1 tsp), Neutral Oil (1 Tbsp), Soy Sauce (1 Tbsp), and Lemon Juice (1/2).
step 2
Poke holes in both sides of the Flank Steak (1 lb) with a fork. Brush with marinade. Cover and marinate the steak for 30 minutes. Don’t discard the marinade.
step 3
Pat the steak dry. Heat a cast-iron skillet over medium-high heat with Neutral Oil (1 Tbsp) and sear steak for 3-4 minutes a side, or until 130 degrees F (55 degrees C) in the middle for medium-rare.
step 4
Transfer steak to a tray and cover with foil. Let it rest for 5-10 minutes.
step 5
To the same pan over medium-high heat, add Butter (2 Tbsp). Once hot, add Button Mushrooms (2 1/4 cups). Cook until mushrooms are softened and begin to brown, 2-3 minutes, then season with Freshly Ground Black Pepper (1/4 tsp).
step 6
Turn the heat to medium and add the All-Purpose Flour (1 tsp), stir until it coats the mushrooms.
step 7
Add the remaining marinade, Beef Broth (1/2 cup), Balsamic Vinegar (1 tsp), Lemon Juice (1/2), and Garlic (1 clove), and cook for 2-3 more minutes, until thickened.
step 8
Cut steak against the grain, then pour the sauce over the top, optionally garnish with Fresh Thyme (4 sprigs), and serve.
