Seared Flank Steak with Fingerlings, Mushrooms & Warm Tomato Pan Sauce
This is the richer option: a more luxurious steak dinner with roasted fingerling potatoes, mushrooms, and a warm tomato-pan sauce. It costs a bit more and feels date-night worthy, but still comes together in under an hour using the stove and oven.
Ingredients
- Choice Boneless Beef Flank Steak (1 Steak) 1 lb $13.99
- Private Selection® Petite Fingerling Gourmet Potatoes 1.5 lb $3.99
- Kroger® Whole White Mushrooms 8 oz $2.39
- Fresh Roma Tomato 1 lb $1.49
- Jumbo Sweet Onions 1 lb $1.59
- Organic Italian Parsley 1 each $1.99
Instructions
- Preheat the oven to 425°F. Take the 1 pound flank steak out of the refrigerator while you prep so it loses some chill and cooks more evenly.
- Halve 1.5 pounds fingerling potatoes lengthwise. Slice 8 ounces white mushrooms. Slice 1/2 pound from the 1 pound sweet onions into thin half-moons. Dice 2 medium Roma tomatoes from the 1 pound package. Chop 2 tablespoons parsley from the 1 bunch Organic Italian Parsley.
- Toss the 1.5 pounds halved fingerling potatoes with 1 tablespoon olive oil, 1/2 teaspoon kosher salt, 1/4 teaspoon black pepper, and a pinch of dried thyme or rosemary from the pantry if you have it. Spread them cut-side down on a sheet pan and roast 25 to 30 minutes, turning once, until deeply golden and tender.
- While the potatoes roast, pat the 1 pound flank steak dry. Season both sides with 1 teaspoon kosher salt and 1/2 teaspoon black pepper. Heat a heavy skillet over high heat until very hot, then add 1 tablespoon oil.
- Sear the 1 pound flank steak for about 4 to 5 minutes on the first side and 3 to 4 minutes on the second side for medium-rare to medium, depending on thickness. Transfer the steak to a cutting board and rest at least 8 minutes so the juices stay in the meat.
- Reduce the skillet heat to medium. Add the sliced 1/2 pound sweet onion and the 8 ounces mushrooms with a small pinch of salt. Cook 5 to 6 minutes, stirring occasionally, until the onions soften and the mushrooms brown.
- Add the diced Roma tomatoes and cook 3 to 4 minutes until they soften and become saucy. Add 2 tablespoons water to loosen the fond from the pan and simmer briefly until lightly reduced. Stir in half the chopped parsley and taste for seasoning.
- Slice the rested flank steak thinly across the grain on a slight diagonal for tenderness and a restaurant-style look.
- Plate by making a bed of roasted fingerling potatoes on each plate, spooning the mushroom-tomato mixture partly over and partly beside the potatoes, then fanning the sliced steak across the top. Finish with the remaining parsley and a drizzle of extra-virgin olive oil if desired.
- Optional wine pairing: Pinot Noir highlights the earthiness of mushrooms without overwhelming the steak, while Cabernet Sauvignon gives a bolder steakhouse-style pairing.
