Picking the Perfect Steak

It can be hard to pick out the right steak, especially if you are a steak-cooking amateur. But don’t worry, we have a few tips that will have you buying steak like a pro whether it’s your first time or your fiftieth.

  1. Get to know your butcher – This tip is the equivalent of ‘phone-a-friend’ for meat buying. There is no one who knows meat better than your butcher so if you don’t know the best cut, don’t be afraid to ask. Your butcher does this for a living and every butcher I’ve met is happy to share their secrets with their customers.
  2. Look for color – Good steak has a deep red color, though grass fed beef is darker than grain finished. The fat should be creamy white or pale yellow. There should be no brown spots in the fat or on the edges of the beef.
  3. Marbling magic – Marbling is what gives your steak it’s moisture and flavor. Always look for small flecks of fat that are well distributed and evenly spread through the whole steak. It is the fat in the middle of the steak that gives the best flavor.

Tips for Cooking Steak

  • Start at room temp – Always make sure that your steak is at room temperature before you start cooking. This ensures that the steaks will cook evenly and won’t dry out while cooking.
  • Cast iron is king – If you have it a cast iron pan makes oven baking your steak a breeze. Get great caramelization for your crust and bake your steak in the same pan.
  • Take the temp – If you don’t have an instant read thermometer in your kitchen already, this is an excellent time to purchase one. A thermometer is the best way to ensure that your steak reaches the perfect doneness without any fuss.

Description

Juicy steak and mushrooms, yes please!


Ingredients

  • 2 Tablespoons of olive oil (30 ml)
  • 4 portabella mushrooms (300 g)
  • 46 sprigs of thyme with the leaves removed
  • 2 beef filet mignons (400 g) (or choose another steak)
  • 1 Tablespoon of garlic powder (10 g)
  • Salt and pepper, to taste

Instructions

  1. Preheat oven to 320°F  (160°C).
  2. Place the portabella mushrooms on a greased roasting tray and drizzle a tablespoon of olive oil over it. Sprinkle the garlic powder evenly over all four and scatter over the picked thyme leaves. Season with salt and freshly ground black pepper and place in the oven for 15 minutes. (When done, tip them to one side to allow excess moisture to run off.)
  3. Season the steaks with salt.
  4. Add one tablespoon olive oil to a large frying pan and sear both sides of the steaks so that a golden crust forms on all sides.  Place the steaks on a rimmed baking tray and place into the preheated oven for 8-10 minutes until the center of the steak reaches 130 F for medium rare or 140 F for medium.  Rest for 10 minutes before serving.
