Beef Stroganoff with Browned Mushrooms
Not rated yet. Be the first.
Mushrooms cooked until the pan goes dry, beef seared hard, and sour cream stirred in off the heat. Spoon it over egg noodles and watch the table go quiet, the good kind of quiet.
The short version
Sear seasoned beef chunks, cook down mushrooms and onion until brown, simmer with broth and tomato paste, then slice the beef and stir it back in with sour cream off the heat. About 50 minutes. Don't let the sauce boil once the sour cream is in.
What makes ours better
the tricks Nonna pretends she never taught me
-
Sear the beef in chunks, then slice it. Big pieces build a brown crust without overcooking the middle. Slicing afterward gives you tender strips that finish gently in the sauce instead of turning gray and chewy.
-
Cook the mushrooms until the pan is dry. Mushrooms release a lot of water first. Once it's gone they brown, and that browning is most of the sauce's flavor.
-
Add tomato paste and Dijon. A spoon of tomato paste adds depth and Dijon adds a sharp edge, so the sour cream tastes bright and not just heavy.

Steps
deep breath. you’ve got this.
-
Season the beef
Pat the beef chunks dry with paper towels and toss them with the salt and pepper. Dry meat browns; wet meat steams. Put a large pot of salted water on to boil for the noodles.
-
Sear the beef
Heat the oil in a large skillet over medium-high heat until it shimmers. Sear the beef in two batches, turning, until deeply browned on all sides, about 6 minutes per batch. Move it to a cutting board. Pour off all but a thin film of fat.
Don't crowd the pan. Touching pieces steam each other and never brown.
About 12 min. Cook mode has a timer for this step.
-
Brown the onion and mushrooms
Lower the heat to medium and melt the butter. Cook the onion for 3 minutes, then add the mushrooms. Cook, stirring and scraping up the browned bits, until the mushroom liquid has boiled off and the mushrooms are golden, about 8 minutes.
About 11 min. Cook mode has a timer for this step.
-
Build the sauce
Stir in the tomato paste and flour and cook for 1 minute. Pour in the broth and Worcestershire, stirring, and simmer for 10 minutes, until slightly thickened. Meanwhile, cook the noodles to the package time and drain.
About 10 min. Cook mode has a timer for this step.
-
Slice the beef
While the sauce simmers, cut each beef chunk into three slabs, then slice across the grain into strips about ¼ inch thick.
-
Add the sour cream
Turn the heat to low. Stir the sour cream and mustard together in a small bowl, then stir in a few spoonfuls of the hot sauce to warm it. Scrape it into the skillet.
Boiling sour cream makes it split and turn grainy. Keep it at a bare simmer or below.
-
Finish and serve
Return the beef and any juices on the board to the skillet. Warm gently for about 2 minutes, until the meat is heated through but still pink in the middle. Taste for salt, stir in the dill, and spoon over the noodles.
About 2 min. Cook mode has a timer for this step.
Good to know
the stuff I’d tell you over the phone
- Tenderloin tips work if you find them, but sirloin or top loin costs less and has more flavor. Skip stew meat; it needs long cooking.
- Room-temperature sour cream is less likely to curdle. Set it out when you start.
- A tablespoon of brandy or dry sherry added with the broth is a nice extra but not needed.
- Storage. Fridge, 3 days. Reheat gently in a skillet over low heat with a splash of broth. Not recommended to freeze; the sauce can separate.
Questions, answered
the questions my cousins text me
What is the best cut of beef for stroganoff?
Sirloin or top loin. Both are tender enough for a quick cook and have real beef flavor. Tenderloin tips also work.
Why did my stroganoff sauce curdle?
The sour cream got too hot. Take the pan to low heat before stirring it in, warm the sour cream with a little hot sauce first, and don't let the sauce boil afterward.
Can I use ground beef?
Yes. Brown 1 pound of ground beef, drain it, and add it in place of the sliced steak at the end. It's more of a weeknight shortcut than a classic stroganoff.
Can I make stroganoff ahead?
Make the sauce through step 4 up to two days ahead. Reheat, then slice and add the freshly seared beef and the sour cream just before serving.
What do I serve with beef stroganoff?
Wide egg noodles are the usual choice. Mashed potatoes or rice also work, with a green salad or green beans alongside.
