Marinade

Method

Marinade

  1. 1

    Prepare the Marinade

    In a bowl, whisk together soy sauce, red wine vinegar, Worcestershire sauce, olive oil, minced garlic, brown sugar, black pepper, and salt until well combined.

  2. 2

    Marinate the Steak

    Place the sirloin steak in a large resealable bag, pour the marinade over it, seal the bag, and refrigerate for at least 2 hours (or overnight for best results).

Caramelized Onions

  1. 3

    Cook the Onions

    In a skillet over medium heat, add the diced bacon and cook until crispy. Remove the bacon and set aside, leaving the drippings in the pan. Add the sliced onions and cook on low heat for about 30 minutes, stirring occasionally, until they are soft and caramelized. Add sherry wine and cook for an additional 5-10 minutes until the liquid is reduced.

Bacon-Cheddar Mash

  1. 4

    Prepare the Potatoes

    Boil the cubed potatoes in salted water until tender, about 15-20 minutes. Drain and return to the pot.

  2. 5

    Mash the Potatoes

    Add butter and milk to the potatoes, and mash until smooth. Stir in the crispy bacon and shredded cheddar cheese. Season with salt and pepper to taste.

Garlicky Spinach & Grilling the Steak

  1. 6

    Grill the Steak

    Remove the steak from the marinade and discard the marinade. Preheat the grill to medium-high heat and grill the steak for about 6-7 minutes per side (for medium-rare), or until desired doneness is reached. Let rest for 5 minutes before slicing.

  2. 7

    Sauté the Spinach

    In a separate skillet, heat olive oil over medium heat. Add minced garlic and sauté for 1 minute. Add fresh spinach and cook until wilted, about 3-4 minutes. Season with salt and pepper to taste.
