Slow Cooker Beef

Slow Cooker Beef Stroganoff

The sour cream goes in on Warm, after the thickening is already done. That order is the whole reason the gravy stays smooth and tan instead of splitting into curds.

Stroganoff has one reliable failure: dairy meeting direct heat. This recipe removes the risk by putting the sour cream in last, with the cooker turned down to Warm and the thickening already finished.

The beef is chuck, cut into inch-and-a-half cubes, and it stays that way. Seven hours makes it tender without turning it into shreds — which is what the finished plate is supposed to show.

Why This Recipe Works

  • Browning the beef in batches builds fond and colour that a covered cooker cannot produce.
  • Twelve ounces of cremini give up their liquid slowly and stay visible rather than dissolving.
  • Dijon and Worcestershire supply the savoury depth that a pale sour-cream sauce would otherwise lack.
  • Thickening before the dairy means the cornstarch is fully cooked out, so the sour cream only has to be warmed through.

Ingredient Notes

Beef chuck
Two pounds in 1 1/2-inch cubes. The long braise is built around this cut, and the cubes are meant to survive it.
Sour cream
One cup, at room temperature, added on Warm. Both conditions exist to stop it splitting.
Wide egg noodles
Twelve ounces, cooked separately. They are plated under the stroganoff rather than cooked in it.

How to Make It

  1. Brown in batches

    Brown the beef in the oil in batches, then transfer it to the slow cooker.

  2. Build and cook

    Add the onion, mushrooms, garlic, broth, Worcestershire, Dijon, paprika, salt and pepper. Cover and cook on Low about 7 hours, until the beef is tender but still in chunks.

  3. Thicken on High

    Mix the cornstarch and cold water, stir it into the cooker, and cook on High 10 to 15 minutes until the gravy lightly thickens.

  4. Sour cream on Warm

    Turn the cooker to Warm and stir in the room-temperature sour cream so the sauce stays smooth and tan.

  5. Serve over noodles

    Spoon the beef, mushrooms and gravy over cooked wide egg noodles and finish with parsley.

Two Pans, One Plate

The noodles are never cooked in the stroganoff. They run on their own track and the two meet only at the moment of serving.

In the skillet, then the slow cooker

  1. Start

    Beef browned in batches in a tablespoon of oil, then moved to the cooker.

  2. About 7 hours on LOW

    Onion, mushrooms, garlic, broth, Worcestershire, Dijon and paprika cook down with the beef until it is tender but still cubed.

  3. 10-15 minutes on HIGH

    Cornstarch slurry stirred in and cooked out until the gravy lightly thickens.

  4. On WARM

    Room-temperature sour cream stirred through, off any real heat, so the gravy turns smooth and tan.

In a separate pot

  1. Near the end

    Twelve ounces of wide egg noodles cooked on their own, so they never absorb the gravy or overcook in it.

Spoon over, do not stir together

The beef, mushrooms and gravy go over the drained noodles at the plate, finished with parsley. Combining them in the cooker would soften the noodles and thin the gravy.

Success Tips

  • Take the sour cream out of the fridge when you start the thickening step. Cold dairy into hot gravy is what curdles.
  • Brown in batches even though it is slower — a crowded pan steams and you lose the colour.
  • Stir gently at the end. The point is chunks, not shreds.

Serving Ideas

Six servings over cooked wide egg noodles, finished with chopped parsley.

Frequently Asked Questions

Why did my sauce split?

Almost always heat or temperature. The sour cream goes in on Warm, not Low or High, and it should be at room temperature first.

Should the beef be shredded?

No. It stays in chunks; that is what the finished dish shows.

Can I cook the noodles in the cooker?

No. They are cooked separately and the stroganoff is spooned over them.
