1tspfresh thyme
½cupbeef broth
1tbspdijon mustard
½tspWorcestershire sauce
¼cupheavy cream
Instructions
Pat the steak dry and season with spices on each side.
In a large skillet over medium-high heat, add olive oil and sear the steaks for 3-5 minutes on each side, or until the desired done-ness is reached. Be sure to use an instant-read meat thermometer. I recommend you remove the steak from the pan when it reaches an internal temperature of 145 degrees F. Remove them from the pan and tent with foil.
Add butter to the pan, then add the halved potatoes and saute them until they’re fork tender. This should take about 10-12 minutes. Remove them from the pan.
Add the minced shallot to the pan, no need to clean it. Saute for 2-3 minutes.
Then add the thyme, give it a stir.
Next deglaze the pan with the beef broth, allow it to bubble and scrape up the brown bits. Then whisk in the dijon mustard until it’s completely smooth.
Turn the heat down to low and whisk in the heavy cream.
Return the steak and potatoes to the pan. Serve!
Notes
Leftovers can be stored in an airtight container in the refrigerator for 3-4 days. Reheating: To reheat, if you want this to taste as good as new, I recommend warming a pan over low heat and adding a splash of beef broth and the leftovers (with the sauce). Cover it and heat it until it’s warmed through. *Nutrition facts are automatically calculated and my not be correct.
