Ingredients:
- 1 pound sirloin steak, thinly sliced into strips
- 2 Tbsp olive oil
- 2 Tbsp unsalted butter
- 1/2 medium onion
- 1/2 brown mushrooms, thickly sliced
- 1 garlic clove
- 1 Tbsp all-purpose flour
- 1 cup beef broth
- 3/4 cup heavy whipping cream
- 1/4 cup sour cream
- 1 Tbsp Worcestershire sauce
- 1/2 tsp dijon mustard
- 1/2 tsp salt
- 1/4 tsp black pepper
- Green onion to garnish
Instructions:
Step One: Place a large deep pan or dutch oven over medium-high heat. Add 2 Tbsp oil and once oil is very hot, add thinly sliced beef strips in a single layer, cooking 1 minute per side without stirring. Cook until just browned and no longer red. Sear beef in 2 batches so you don’t overcrowd the pan. Remove beef to a plate and cover to keep warm
Step Two: Add 2 Tbsp butter, chopped onion and sliced mushrooms. Sautee 6-8 minutes or until liquid has evaporated and onions and mushrooms are soft and lightly browned
Step Three: Add 1 minced garlic clove and sautee 1 minute until fragrant. Add 1 Tbsp flour and sautee another minute stirring constantly
Step Four: Pour in 1 cups beef broth, scraping any bits from the bottom of the pan then add 3/4 cup whipping cream and simmer another 1 to 2 minutes or until slightly thickened
Step Five: Stir a few Tablespoons of the sauce into 1/4 cup of sour cream to temper it so the sour cream doesn’t curdle then add it to the pan while stirring constantly
Step Six: Stir in 1 Tbsp Worcestershire, 1/2 tsp dijon mustard, and season with 1/2 tsp salt and 1/4 tsp pepper, or season to taste and continue simmering until sauce is creamy. Add beef with any accumulated juices back to the pan and bring just to a simmer or until beef is heated through
