Ingredients You'll Need
Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.
- 1 lb Beef sirloin steak (cut into thin strips)
- 1 medium Yellow onion (chopped)
- 8 oz Cremini mushrooms (sliced)
- 2 cloves Garlic (minced)
- 12 oz Egg noodles
- 1.5 cups Beef broth
- 1 cup Sour cream
- 1 tablespoon Dijon mustard
- 1 tablespoon Worcestershire sauce
- 2 tablespoons All-purpose flour
- 2 tablespoons Olive oil
- to taste Salt
- to taste Black pepper
- 2 tablespoons Fresh parsley (chopped, for garnish)
Step-by-Step Instructions
- 1
Prepare the beef by patting it dry with paper towels. Season the beef strips generously with salt and pepper. This helps to create a flavorful crust when searing.
~3 min
- 2
Heat olive oil in a large skillet over medium-high heat. Add the beef in a single layer and sear for 2-3 minutes per side, until browned. Avoid overcrowding the pan; sear in batches if necessary to achieve a good sear. Remove the beef from the skillet and set aside.
~7 min
- 3
Add the chopped onion to the skillet and cook until softened and translucent, about 5 minutes. Stir occasionally to prevent burning and ensure even cooking. The onions should become fragrant and slightly sweet.
~5 min
- 4
Add the sliced cremini mushrooms to the skillet and cook until they release their moisture and turn golden brown, about 7 minutes. The mushrooms will shrink as they cook, and their flavor will intensify.
~7 min
- 5
Stir in the minced garlic and cook for 1 minute, until fragrant. Be careful not to burn the garlic, as it can become bitter.
~1 min
- 6
Sprinkle the flour over the vegetables and cook for 1 minute, stirring constantly. This will help to thicken the sauce later. Ensure the flour is evenly distributed and cooked through.
~1 min
- 7
Gradually whisk in the beef broth, scraping up any browned bits from the bottom of the skillet. These browned bits add a lot of flavor to the sauce.
~2 min
- 8
Bring the sauce to a simmer and cook until slightly thickened, about 5 minutes. The sauce should be able to coat the back of a spoon.
~5 min
- 9
Stir in the Dijon mustard and Worcestershire sauce. These add depth and complexity to the sauce's flavor.
~1 min

Reduce the heat to low and stir in the sour cream. Do not boil the sauce after adding the sour cream, or it may curdle. Gently incorporate the sour cream until the sauce is smooth and creamy.
~2 min

Return the seared beef to the skillet and heat through. Ensure the beef is warmed through but not overcooked. Simmer gently for a couple of minutes.
~2 min

Meanwhile, cook the egg noodles according to package directions. Drain the noodles and serve the beef stroganoff over the noodles. Garnish with fresh parsley.
~10 min
How Do I Know It's Ready?
The beef should be browned on the outside and slightly pink inside. The sauce should be thick enough to coat the back of a spoon.
