  • 10 ounces top sirloin
  • Freshly ground black pepper
  • Salt

Mustard Sauce

  • 1 cup sliced mushrooms*
  • 1 green onion thinly sliced
  • 1 clove garlic diced
  • 1 cup beef broth
  • 2 tablespoons sour cream
  • 1 tablespoon Dijon mustard

Serve With

  • Steamed green beans



  • Preheat your broiler on high and line a rimmed baking sheet with foil and lightly grease.
  • Lightly score 4 shallow cuts on both sides of the steak, two in each direction (per piece of meat if your sirloin is in smaller pieces).
  • Sprinkle both sides generously with freshly cracked pepper and salt.
  • Place steak on the prepared baking sheet and broil for 4 to 6 minutes per side, until steak reaches your desired level of doneness. Remove from oven, tent with foil, and allow to rest for at least 5 minutes before slicing across the grain.


  • While your steak is cooking, heat a medium skillet over medium heat and lightly grease with cooking spray or a small drizzle of olive oil. Add mushrooms and sliced green onions. Saute until mushrooms are lightly browned, 3 to 4 minutes. Add garlic and cook for 30 seconds.
  • Transfer vegetables to a plate and return pan to heat.
  • Add beef broth to your pan and bring to a simmer. Simmer for 3 to 4 minutes until reduced by half. Remove from heat and whisk in sour cream and mustard. Add salt and pepper to taste (if you use full-sodium beef broth, you probably wont need salt). If not ready to serve, you can keep the mixture warm over very low heat--do not boil.
  • Serve steak alongside steamed green beans, with mustard sauce spooned over both. Enjoy!


*I use button mushrooms, but you can use whatever mushrooms you like best.
Doubling Instructions: Recipe doubles with no changes except a slightly longer simmering time for the broth to reduce by half.
