Cooking Instructions
Prepare the Ingredients: Begin by cutting the chuck roast into uniform, bite-sized pieces for even cooking.
Dice the onions and slice the mushrooms to ensure easy preparation.
Sear the Beef (Optional): In a skillet over medium-high heat, add a bit of oil.
Sear the beef in batches until it develops a golden-brown crust, which will enhance the overall flavor of the dish.
Assemble in the Crock Pot: Layer the seared beef, diced onions, minced garlic, and sliced mushrooms in the Crock Pot.
Pour in the beef broth, Worcestershire sauce, and Dijon mustard.
Sprinkle with paprika, salt, and pepper, then stir gently to combine all ingredients.
Cook the Stroganoff: Set the Crock Pot to low for 7-8 hours or high for 4-5 hours.
Check the beef toward the end of the cooking time to ensure it is fork-tender and the flavors are well combined.
Thicken the Sauce: In a small bowl, whisk together the flour and water to create a smooth slurry.
Stir this slurry into the Crock Pot, and cook on high for an additional 20-30 minutes to thicken the sauce.
Finally, stir in the sour cream just before serving.
