Ingredients
- 2 pounds beef stew meat or chuck roast, cut into 1-inch cubes
- Salt and pepper, to taste
- 1 tablespoon olive oil
- 1 small onion, diced
- 8 ounces mushrooms, sliced
- 3 cloves garlic, minced
- 2 cups beef broth
- 2 tablespoons Worcestershire sauce
- 1 tablespoon tomato paste
- 1 teaspoon dried thyme
- 3 tablespoons all-purpose flour
- ½ cup sour cream
- Fresh parsley, chopped, for garnish
- Egg noodles or mashed potatoes, for serving
Instructions
- Sear the beef. Season the beef cubes with salt and pepper. Heat olive oil in a skillet over medium-high heat and sear the beef in batches for 2–3 minutes per side, until browned. Transfer to the slow cooker as you go. (This step is optional but adds a lot of flavor.)
- Add the vegetables. Add the onion, mushrooms, and garlic to the slow cooker along with the beef.
- Build the sauce. In a bowl, whisk together the beef broth, Worcestershire sauce, tomato paste, and thyme. Pour this over the beef and vegetables.
- Slow cook. Cover and cook on low for 7–8 hours or high for 4 hours, until the beef is fork-tender.
- Thicken the sauce. About 30 minutes before serving, whisk the flour with a few tablespoons of the hot cooking liquid to make a smooth paste, then stir it back into the slow cooker. Cover and continue cooking until thickened.
- Finish with sour cream. Turn off the heat and stir in the sour cream until smooth and creamy. Avoid boiling after this point, as it can cause the sauce to curdle.
- Serve. Spoon the stroganoff over egg noodles or mashed potatoes, and garnish with fresh parsley.
Tips for success
- Don’t skip searing the beef if you have the extra 10 minutes — it builds a deeper flavor base for the whole dish.
- Add the sour cream at the very end, off the heat, to keep the sauce smooth and prevent curdling.
- Use beef stew meat or chuck roast — both have enough marbling to stay tender over a long, slow cook.
- Let the sauce rest for a few minutes before serving so it thickens slightly further.
What to serve it with
- Buttered egg noodles
- Creamy mashed potatoes
- Steamed green beans or a simple side salad
Frequently asked questions
Can I use ground beef instead? Yes — for a quicker stovetop version, brown ground beef and simmer with the same sauce ingredients for about 20 minutes instead of using the slow cooker.
Can I make this ahead of time? The stroganoff base (before adding sour cream) can be made a day ahead and reheated gently, then finish with sour cream just before serving.
Can I freeze leftovers? Cream-based sauces can separate when frozen and reheated, so this dish is best enjoyed fresh or as next-day leftovers rather than frozen.
Can I use Greek yogurt instead of sour cream? Yes — plain Greek yogurt is a good substitute and adds a similar tangy creaminess.
