Method
Prepare the Beef
- Pat beef strips dry with paper towels. Season with salt and pepper. Toss with flour until lightly coated.
- Heat olive oil in a large skillet or Dutch oven over medium-high heat. Brown beef in batches, about 1-2 minutes per side. Do not overcrowd the pan. Remove beef to a plate and set aside.
Sauté Vegetables
- Reduce heat to medium, add butter to the same skillet. Add sliced onions and cook until softened and translucent, about 5-7 minutes.
- Add sliced mushrooms and cook until golden brown and tender, about 5-8 minutes. Stir in minced garlic and cook for 1 minute until fragrant.
Build the Sauce
- Stir in Dijon mustard. Deglaze the pan with white wine (if using), scraping up any browned bits from the bottom. Let it reduce by half, about 2-3 minutes.
- Pour in beef broth and bring to a simmer. Return the browned beef (and any accumulated juices) to the skillet. Reduce heat to low, cover, and simmer for 10-15 minutes, or until beef is tender.
Finish and Serve
- While the stroganoff simmers, cook egg noodles according to package directions. Drain well.
- Remove the skillet from the heat. Gradually whisk in the room-temperature sour cream until fully combined and the sauce is creamy. Do not boil the sauce after adding sour cream, as it may curdle.
- Taste and adjust seasoning if needed. Serve immediately over hot egg noodles, garnished with fresh chopped parsley.
Notes
For best results, ensure sour cream is at room temperature before adding to prevent curdling. You can substitute beef broth for white wine if preferred. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop.
