A note about serious food allergies

Diane was Ted Danson's love on “Cheers,” and Diane (and Jack) inspired a little ditty by John Cougar Mellencamp in the early 80s. But Diane, for our purposes, is a delectable and divine steak preparation, fried with pan juices that are made into sauce. (In restaurants, they sometimes serve it flambéed tableside. We do not recommend that here.) This steak Diane also has creamy mashed potatoes and fresh asparagus; no 80s references there. Delicious, delectable, divine… Diane.

  1. 1

    Prepare the Ingredients

    Cut potatoes into large evenly-sized chunks. Trim woody ends off asparagus. Cut mushrooms into ¼" slices. Pat steaks dry, and season both sides with a pinch of salt and pepper.

  2. 2

    Make the Mashed Potatoes

    Bring a medium pot with potato chunks and enough water to cover to a boil. Reduce to a simmer and cook until softened, 8-10 minutes. Reserve ½ cup potato cooking water. Drain potatoes in a colander and return to pot. Add 2 tsp. olive oil, truffle butter, and ½ tsp. salt. Mash until smooth. If too dry, add reserved potato cooking water, 1 Tbsp. at a time, until desired consistency is reached. While potatoes cook, roast asparagus.

  3. 3

    Roast the Asparagus

    Place asparagus on prepared baking sheet and toss with 1 tsp. olive oil, ¼ tsp. salt, and a pinch of pepper. Spread into a single layer and roast in hot oven until tender, 8-12 minutes. If asparagus finishes roasting before other components, tent with foil. While asparagus roast, cook steaks.

  4. 4

    Cook the Steaks

    Place a medium non-stick pan over medium-high heat and add 1 tsp. olive oil. Add steaks to hot pan and cook until browned and steaks reach a minimum internal temperature of 145 degrees, 5-7 minutes per side. Remove steaks to plate and rest, 5 minutes. Reserve pan; no need to wipe clean. While steaks rest, make sauce.

  5. 5

    Make Sauce and Finish Dish

    Return pan used to cook steaks to medium-high heat. Add 1 tsp. olive oil and mushrooms to hot pan. Stir often until browned, 4-5 minutes. Stir in demi-glace, cream cheese, ¼ cup water, and a pinch of salt and pepper. Bring to a simmer. Once simmering, remove from burner. Plate dish as pictured on front of card, topping steaks with sauce. Bon appétit!
