Want to class up the joint? Bring a higher class of heckler to your dinner table? You'll be beating the paupers off with a stick when you have this steak and white wine demi-glace on the menu. (Even the words sound like you're a fancy pants.) Potatoes are roasted in butter and tossed with garlic, peas, and herbs. Those same herbs are added to the delectable sauce, a rich troika of white wine, demi-glace, and butter. We'd say you'll be licking your fingers after, but you're way too posh for that.
Cut potatoes into ½" dice.
Place a medium oven-safe pan over medium-high heat and melt half the butter (reserve remaining for sauce). Add potatoes and stir, 1 minute.
Cover, reduce heat to medium, and cook 5 minutes, stirring once halfway through.
Uncover, place pan in hot oven, and roast until golden brown and tender, 20-22 minutes, stirring once halfway through.
Season with ¼ tsp. salt and a pinch of pepper. Set aside.
While potatoes roast, prepare ingredients.
Prepare the Ingredients
Stem and mince parsley and oregano.
Pat steaks dry, and season both sides with ½ tsp. salt and ¼ tsp. pepper.
Cook the Steaks
Place a medium pan over medium heat. Add 2 tsp. olive oil and steaks to hot pan.
Cook until steaks are browned and reach a minimum internal temperature of 145 degrees, 5-7 minutes per side.
Remove steaks to a plate, tent with foil, and rest at least 3 minutes.
Reserve pan; no need to wipe clean.
While steaks cook, finish potatoes.
Finish the Potatoes
Carefully, stir peas and garlic into cooked potatoes.
Return pan to oven and bake until peas warm through, 2-3 minutes.
Stir in parsley, oregano (reserve pinches of both for sauce), ¼ tsp. salt, and ¼ tsp. pepper. Set aside.
Make the Sauce
Return pan used to cook steaks to medium-high heat. Add white cooking wine and beef demi-glace to hot pan and bring to a boil. Cook until liquid is reduced by half, 1-3 minutes.
Remove from burner and swirl in remaining butter. Add any accumulated juices from resting steaks, remaining parsley, and remaining oregano.
