Equipment

  • roaster
  • Meat thermometer

Ingredients
  

  • 2 lb flank steak whole piece
  • 2 onions quartered
  • 3 garlic cloves whole
  • 2 tablespoons white sugar
  • 2 tablespoons tomato paste
  • 1 tablespoon white wine vinegar
  • 2 branches fresh thyme or 1/2 teaspoon dried thyme
  • 2 tablespoons olive oil extra virgin
  • 1 teaspoon salt
  • Black pepper to taste

Instructions
 

  • Start preparing the marinade. In a large bowl with lid or ziplock bag add the beer, garlic, sugar, vinegar, tomato paste, salt, black pepper, close and mix.
  • With a sharp knife, cut superficially the meat’s fat.
  • Arrange the beef inside the bowl or ziplock so the marinate covers all sides of your beef. Leave in the fridge from 2 hours up to 24 hours marinating.
  • When ready to cook, preheat your oven at 392 º F / 200ºC.
  • Remove the flank steak from the marinade and transfer to a sieve over a bowl to drip extra marinade. Reserve the marinade.
  • Arrange the sliced vegetables in a roaster, start with the onions covering the whole surface of roaster. Season with salt and pepper to taste.
  • Arrange the beer marinated flank steak over the onions, add the remaining veggies on the roaster corners and pour the marinade, but don’t pour over the meat.
  • Roast for 35 minutes at 392ºF / 200ºC until meat and vegetables are golden brown.
  • Check the internal temperature of beef with a meat thermometer. For a medium rate, it should be at least 135ºF / 57ºC. For well done, cook until it reaches 150ºF / 65ºC.
  • Remove the roaster from the oven, transfer the meat to a chopping board or plate and leave to rest for 10 minutes before slicing.
  • Pour the liquids from the roaster in a sauceboat and roasted veggies to another bowl.
  • After resting, cut the meat against the grain for the most tender cut of beef and serve.

Notes

  • Cut the meat’s fat: Really important step to help the meat absorb the flavors of marinade and accelerating the melting process of fat when roasting.
  • Nail the rareness of your beef: if you have a meat thermometer, insert into the meat to check the temperature: 
Medium rate, it should be at least 135ºF / 57ºC.
For well done, cook until it reaches 150ºF / 65ºC.
