Make this traditional Beef Stroganoff in the Slow Cooker with simple ingredients that add so much flavor. The sauce is extra creamy with lots of ways to thicken it up at the end!
Ingredients
2 ½ pounds stew meat, cut into 1-inch cubes
1 teaspoon garlic salt
½ teaspoon black pepper
¼ cup flour
3-6 tablespoons olive oil
3 Tablespoons cold butter, separated
½ cup white wine, see notes
16 oz. button Mushrooms
1 small yellow onion, diced
4 cloves garlic, minced
4 cups beef broth
1 tsp better than bouillon, or 1 beef bouillon cube
2 Tablespoons red wine vinegar
2 Tablespoons Worcestershire sauce
2 Tablespoons Dijon mustard
To thicken:
¼ cup cornstarch + ¼ cup cold water
1 ½ cups Sour Cream, not reduced fat
10.5 oz. cream of mushroom soup, optional
For Serving:
1 pound wide homestyle Egg Noodles
Instructions
Cut the beef into one-inch cubes and pat completely dry. Discard any large pieces of fat. Fat that’s marbleized into the meat is fine!
Season with garlic salt and pepper. Sprinkle with flour and toss to coat.
Heat 2 Tablespoons olive oil in a skillet over medium-high heat. Sear the meat in batches for 45 seconds per side, until browned but not cooked through. Use kitchen tongs to carefully remove and set aside on a plate. Add more olive oil between batches as needed and decrease heat slightly if the pan gets too hot.
Add 1 Tablespoon butter and white wine to the pot over medium heat. Use a silicone spatula to “clean” (deglaze) the bottom of the pan. Add the onions and mushrooms and cook for 4 minutes. Add the minced garlic and cook for 1 more minute. Remove from heat.
Add the beef broth, bouillon, red wine vinegar, Worcestershire sauce, and Dijon mustard to the Slow Cooker and stir to combine. Add the beef as well as any juice that may have dripped onto the plate. Add the onions/mushrooms/garlic.
Cook on high for 4-5 or on low for 8-9 hours.
Combine the cornstarch/cold water mixture and whisk it into the Slow Cooker.
Flip to warm.
In a medium bowl, whisk sour cream with 1 cup liquid from the slow cooker until smooth. Add to Slow Cooker and stir carefully to combine.
Stir in the condensed cream of mushroom soup if desired. (My homemade version adds even more thickness and flavor.)
Finally, turn heat off and swirl in 2 Tablespoons of cold butter. This adds a smooth, velvety finish.
Serve over egg noodles. If desired, add cooked/drained egg noodles right to the Slow Cooker, stir to combine, and serve!
Notes
Pinot Grigio or Sauvignon Blanc are great wine choices in this recipe. Chicken broth can be used if you don’t cook with wine.
