Ingredients
Method
Preparation
- Pat slices of beef dry and season with salt and pepper.
- Slice the beef against the grain for tenderness.
Cooking
- Heat 1 tbsp of butter and 1 tbsp of oil in a heavy skillet over medium-high heat.
- Quickly sear the beef in batches for 1-2 minutes per side until browned but not fully cooked. Remove and rest on a plate.
- Lower heat to medium. Add remaining butter if needed.
- Cook onions until translucent, about 4-5 minutes. Add garlic and cook for an additional 30 seconds.
- Add mushrooms and sauté until they lose moisture and start to brown, about 5-6 minutes. Season lightly.
- Sprinkle flour (if using) and cook for 1 minute.
- Pour in beef stock and Worcestershire sauce, scraping browned bits from the pan. Stir in the Dijon mustard and simmer for 2-3 minutes until slightly reduced.
- Remove the pan from direct heat and stir in sour cream until combined. Return to low heat and add the beef back for a minute just to warm through. Do not boil.
Serving
- Serve over buttered egg noodles, mashed potatoes, or rice.
- Garnish with chopped parsley.

Notes
Greek yogurt can replace part of the sour cream for tang. For a gluten-free thickener, use a cornstarch slurry. Best served over buttered egg noodles, but can also work with mashed potatoes or rice.
