Step-by-Step Instructions

  1. Prep: Adjust the oven rack to top position and preheat to 425 degrees. Wash and dry all produce. Trim, peel, and cut carrots into 1-inch-thick pieces. Dice potatoes into ½-inch pieces, and slice the onion and mushrooms.
  2. Cook Carrots & Mash: Toss carrots with oil, salt, and pepper on a baking sheet and roast until browned and tender, about 25-30 minutes. Boil potatoes until tender, about 15-20 minutes, then mash with sour cream. Keep covered off heat.
  3. Caramelize Onion: Cook onion in oil until browned. Add sugar and water, cooking until caramelized. Transfer to a bowl and set aside.
  4. Cook Steak: Season steak with salt and pepper. Cook in the same pan as onions to desired doneness, 3-6 minutes per side. Let rest.
  5. Make Sauce: In the same pan, add butter and mushrooms, cooking until softened. Stir in garlic, demi-glace, and water, then mustard. Simmer until thickened.
  6. Finish & Serve: Slice steak against the grain. Plate mashed potatoes, carrots, and steak. Top potatoes with caramelized onion and steak with mushroom sauce.

Chef’s Tip

To enhance the richness of the sauce, consider adding an extra tablespoon of butter just before serving.
