1-First, prepare all ingredients by trimming and cutting the beef into bite-sized pieces, dicing onions, slicing mushrooms, and mincing garlic. This setup helps everything cook evenly.

2-In a skillet, brown the beef pieces on medium-high heat to lock in juices and enhance flavor, though you can skip this for a quicker version.

3-Transfer the browned beef, onions, mushrooms, and garlic to the slow cooker. Add beef broth, Worcestershire sauce, Dijon mustard, and other liquids for that rich base. Cover and cook on low for 6-8 hours or high for 3-4 hours until the beef is tender, adapting for dietary needs as needed.

4-About 30 minutes before serving, stir in a flour or cornstarch mixture to thicken the sauce. Then, gently mix in sour cream for creaminess, adjusting for low-calorie or vegan options. Finally, taste and season before serving over egg noodles it’s that simple!

5-The directed steps from the recipe include patting the beef dry, searing it briefly, deglazing with wine, and slow cooking everything together. This method ensures tender results in about 4-5 hours on high or 8-9 hours on low.
