Creamy Classic Beef Stroganoff Recipe

Ingredients

Beef & Vegetables

• 1 lb (450 g) beef sirloin, thinly sliced into strips
• 8 oz (225 g) cremini or button mushrooms, sliced
• 1 medium yellow onion, thinly sliced

Sauce Components

• 1 cup beef broth (low‑sodium)
• 2 tbsp Dijon mustard
• 1 cup sour cream (full‑fat)
• 2 tbsp all‑purpose flour

Seasonings & Garnish

• 2 cloves garlic, minced
• 1 tsp smoked paprika
• Salt and freshly ground black pepper, to taste
• 2 tbsp unsalted butter
• Fresh parsley, chopped (for garnish)

Instructions

Building the Sauce

1. Heat the skillet. Place a large skillet over medium‑high heat and melt 1 tbsp butter. When the butter foams and begins to turn golden, the pan is ready for searing.
2. Sear the beef. Add the beef in a single layer, working in batches if necessary. Cook 2‑3 minutes per side until a deep brown crust forms; avoid stirring to preserve the caramelized exterior. Remove the meat and set aside.
3. Sauté aromatics. Reduce heat to medium, add the remaining butter, then toss in onions and mushrooms. Cook 5‑6 minutes, stirring occasionally, until the onions become translucent and the mushrooms release their juices.
4. Deglaze and thicken. Sprinkle the flour over the vegetables, stirring to coat evenly. Cook 1‑2 minutes to eliminate raw flour taste. Gradually whisk in beef broth, scraping the browned bits from the pan—they’re flavor gold.
5. Finish the sauce. Stir in Dijon mustard, minced garlic, and a pinch of extra paprika. Reduce the heat to low, then fold in sour cream until the sauce is smooth. Return the seared beef to the skillet, coat with sauce, and simmer gently for 3‑4 minutes.
