Ingredients: 1 pound flat iron steak (could also use flank steak) olive oil, kosher salt, pepper 1 14 oz can beef broth 1 cup whiskey (I used Jack Daniels) 1 Tbsp dijon mustard And so on.
Step number one. Drizzle both sides of the steak with some olive oil and sprinkle with kosher salt and pepper and set aside.
Step 02, In a saucepan add the beef broth, whiskey, and dijon mustard. Once it comes to a boil, turn the heat down to medium. Cook 10 minutes, stirring occasionally.
Step 03, Add the heavy cream, garlic powder, and red pepper flakes. Cook 5-8 more minutes, stirring occasionally. Whisk in the cornstarch during the last 2 minutes. Taste for seasoning and add kosher salt and pepper to taste.
