Ingredients
Wagyu Steak
- 2 New Zealand Grass-Fed Wagyu New York Strip Steaks from First Light, approx. 12 oz each
- 1 tsp coarse sea salt
- 1 tsp fresh cracked black pepper
Creamy French Onion Mushrooms
- 2 tbsp butter
- 1 cup onions, thinly sliced
- 16 oz baby bella mushrooms, sliced
- 3 cloves garlic, minced
- 1 tbsp French onion dip mix
- 2 tbsp cornstarch
- ½ cup beef broth
- ½ cup half-and-half
- ¼ cup parmesan cheese, grated
Instructions
Grass-fed Wagyu Steak
- Remove the steaks from the refrigerator and allow them to come to room temperature for 60 minutes.
- Season all sides of the steaks with coarse sea salt and fresh cracked black pepper.
- Heat a cast iron skillet on the stove over high heat.
- Once the skillet is hot, add the steaks and sear for 2 minutes per side.
- Reduce the heat to medium high and continue cooking the steaks for 3 minutes per side, or until the internal temperature of the steak reaches your desired doneness. (Refer to the notes below for cooking temperatures.)
- Remove the steak from the skillet and wrap in foil.
- Allow to rest for 5-10 minutes before slicing.
- Slice and serve immediately.
Creamy French Onion Mushrooms
- Add the butter to a large skillet over medium high heat.
- Once the butter is melted, add the onions, sauté for 5 minutes.
- Add the mushrooms, garlic and French onion dip mix, sauté for 6 minutes.
- Sprinkle the cornstarch over the mushrooms, then add the beef broth and simmer for 1-2 minutes.
- Reduce the heat to medium-low and add the half and half, cook for 6 minutes.
- Stir in the parmesan cheese and serve.
Notes
- I recommend preparing the mushrooms while the steaks are coming up to room temperature. The mushrooms can then simmer on the side while you sear the grass-fed Wagyu.
