A note about serious food allergies

"You're smothering me!" is not something you want to hear from someone, unless that someone happens to be a juicy flat iron steak. Topping steak with a generous helping of caramelized onions and mushrooms finished with luscious demi-glace is just the kind of stifling we can get behind. Served alongside fresh green beans and mashed roasted sweet potatoes, no one will hold it against you if you can't seem to give this meal any personal space.

    1

    Prepare the Ingredients

    Peel and halve onion. Slice halves into thin strips (julienne). Cut mushrooms into ¼" slices. Trim ends off green beans. Peel sweet potato and dice into ½" pieces. Rinse steaks, pat dry, and season with a pinch of salt and pepper.

  • Step 2 - Roast Potatoes and Green Beans
    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.

  • Step 3 - Caramelize Onions and Mushrooms

    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.

  • Step 4 - Mash Sweet Potatos

    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.

  • Step 5 - Cook the Steaks

    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.

  • Step 6 - Plate the Dish

    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.
