Method
Brown the beef
- Heat a large skillet over medium-high heat, then brown the ground beef, breaking it apart until no longer pink. Drain excess fat so the sauce stays rich but not greasy.
Build the mushroom base
- Add diced onion and sliced mushrooms to the skillet and cook for 5 minutes, stirring occasionally, until softened. Add minced garlic and cook 1 more minute, until fragrant and lightly golden.
- Sprinkle flour over the meat mixture and stir to coat, cooking for 1 minute to remove the raw flour taste. Look for a slightly thickened, glossy coating on the beef.
Make it creamy
- Pour in beef broth and Worcestershire sauce, stirring to deglaze the pan and scrape up browned bits. Stir in Dijon mustard until smooth.
- Simmer for 8–10 minutes, stirring now and then, until the sauce thickens enough to lightly coat a spoon. Remove from heat, then stir in sour cream until the sauce turns golden-brown and creamy.
Combine and serve
- Toss the sauce with cooked wide egg noodles until fully coated and steaming. Season with salt and black pepper to taste.
- Serve immediately, topped with fresh parsley for a bright green finish. The noodles should look saturated in creamy mushroom sauce with visible beef throughout.
Notes
Pro tip: to keep the sour cream silky, remove the skillet from heat before stirring it in, and avoid boiling after that step. Store leftovers in the refrigerator up to 3 days; reheat gently on the stovetop with a splash of broth or water to loosen the sauce. Freezing is not recommended because the noodles and sour cream can separate upon thawing. For a lighter option, use light sour cream and 90% lean or lean ground beef.
