Instructions
Prepare the Beef
Start by slicing your beef into thin strips, about ¼ inch thick. To make this easier, freeze the meat for 15–20 minutes beforehand so it firms up. Toss the beef strips with flour, salt, and pepper in a bowl until evenly coated. This helps create a light crust and thickens the sauce later.
Brown the Beef
Heat 1 tablespoon of oil in a large skillet over medium-high heat. Add the beef in batches to avoid overcrowding. Sear the beef until browned on both sides, about 2–3 minutes per side. Don’t worry about fully cooking it now—just get some good browning. Remove the beef to a plate and repeat with the remaining pieces, adding a bit more oil as needed.
Sauté Onions and Mushrooms
Lower the heat to medium and add 1 tablespoon of butter to the same skillet. Add the sliced onions and a pinch of salt. Cook for about 10 minutes, stirring occasionally, until onions are deeply golden and caramelized. Add the mushrooms and cook until they release their moisture and begin to brown—about 7 more minutes. Then stir in the garlic and cook for 1 minute until fragrant.
Build the Sauce
Add the tomato paste to the onion-mushroom mixture and cook for 2 minutes to caramelize. Deglaze the pan with beef broth, scraping up any browned bits from the bottom. Stir in the Worcestershire sauce and optional Dijon mustard.
Simmer with Beef
Return the seared beef (and any accumulated juices) to the skillet. Simmer gently over low heat for 10–15 minutes until the beef is tender and the flavors meld. If you used a tougher cut, such as chuck or stew meat, you can cover and cook over very low heat for an additional 30 minutes to make it extra tender—very similar to a beef stroganoff crockpot style method.
Finish with Sour Cream
Turn off the heat and stir in the sour cream. Do this off the heat to prevent curdling and keep the sauce creamy. Adjust seasoning with salt and pepper if needed.
Cook the Noodles
While the sauce simmers, cook the egg noodles in salted boiling water according to package instructions (usually 8–10 minutes). Drain and toss with a bit of butter for extra richness.
Serve It Up
Plate the buttery egg noodles and ladle generous portions of the stroganoff over them. Garnish with freshly chopped parsley and serve immediately.
