Although this recipe calls for a high quality steak, stroganoff sauce has humble ingredients that produce rich and memorable flavor. The original sauce has been modified as it has traveled the world. Some have added wine (like this slow cooker stroganoff) and a variety of seasonings, but the base of a good stroganoff sauce is simple.

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.
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.
Add 1 minced garlic clove and sautee 1 minute until fragrant. Add 1 Tbsp flour and sautee another minute stirring constantly.
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.
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.
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.
