Method
- Season beef strips with salt and black pepper. Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat until shimmering.
- Add beef strips in a single layer (work in batches to avoid overcrowding) and sear for 1 to 2 minutes per side until browned but still pink inside. Transfer to a plate and set aside.
- In the same skillet, melt remaining 1 tablespoon butter over medium heat. Add onions and garlic, sautéing until softened, about 3 minutes.
- Stir in sliced mushrooms and cook until golden brown, about 5 minutes. Sprinkle in smoked paprika and Dijon mustard, stirring well to combine.
- Pour in white wine (or beef broth), scraping up any browned bits from the bottom of the pan. Let simmer for 2 minutes to cook off the alcohol.
- Add beef broth and Worcestershire sauce, stirring to combine. Lower heat to medium-low.
- Stir in sour cream over low heat, making sure it blends smoothly into the sauce without boiling. Add fresh thyme and season with salt and pepper to taste.
- Return seared beef strips to the skillet, tossing gently in the sauce for 1 to 2 minutes until warmed through.
- Serve immediately over cooked egg noodles, rice, or mashed potatoes. Garnish with chopped parsley and extra black pepper.
Notes
For best results: Use high heat for searing to lock in juices. Do not overcrowd the pan when cooking beef. Deglaze thoroughly for maximum flavor. Avoid boiling after adding sour cream to prevent curdling. Slice beef against the grain for maximum tenderness.
