  1. 1

    Prepare the Ingredients

    Peel and halve onion. Slice halves into thin strips (julienne). Cut mushrooms into 1/4" slices. Trim ends off green beans. Peel sweet potato and dice into 1/2" pieces. Rinse steaks, pat dry, and season with a pinch of salt and pepper.

  2. 2

    Roast Potatoes and Green Beans

    Add diced sweet potato to one side of prepared baking sheet. Toss with 2 tsp. olive oil and season with a pinch of salt and pepper. Roast in oven for 10 minutes. Remove baking sheet from oven and add green beans to other side. Combine green beans with 1 tsp. olive oil, provided sea salt, and a pinch of pepper (be careful, as pan will be hot). Roast 8-10 minutes, or until both potatoes and green beans are fork tender.

  3. 3

    Caramelize Onions and Mushrooms

    While vegetables cook, heat 2 tsp. olive oil in a medium pan over medium heat. Add onions and cook, stirring occasionally, 10-12 minutes, or until browned. Move onions to edges of pan, making a hole in the middle. Add 1 tsp. olive oil and mushrooms into the void. Allow mushrooms to brown in place 2-3 minutes, then stir until tender, about 2 minutes. Add demi-glace and 2 Tbsp. water. Stir until just combined and remove pan from heat. Add half the butter and swirl to combine. Season with a pinch of salt and pepper. Remove to a plate and wipe pan clean.

  4. 4

    Mash Sweet Potatos

    Remove roasted sweet potatoes to a medium mixing bowl and combine with brown sugar and remaining butter. Mash with a potato masher or fork and season to taste with a pinch of salt and pepper, if desired.

  5. 5

    Cook the Steaks

    Heat pan used for mushrooms over medium-high heat with 1 tsp. olive oil. Add steaks to pan and sear 4-5 minutes on first side until well-browned. Flip and cook 4 minutes, or until steaks reach a minimum internal temperature of 145 degrees. Remove steaks and let rest at least 5 minutes.

  6. 6

    Plate the Dish

    Place a serving of sweet potato mash and green beans on a plate. Place steak in front and top (smother, rather) with rich onion-mushroom sauce.
