The easiest, most delicious, melt-in-your-mouth slow cooker Beef Stroganoff. I love a good ‘set it and forget it’ meal! This is the perfect cozy dinner for these upcoming chilly months.
Coat slow cooker with cooking spray. Toss sirloin in salt/pepper/flour (shake off excess flour). In cast iron skillet with butter sear sirloin on both sides then remove, dice into squares and place in the slow cooker. Add the mushrooms, onion, garlic, beef broth, and Worcestershire sauce, and stir to combine. Cover and cook until the beef is tender, 6 to 8 hours on the LOW setting, or 3 to 4 hours on the HIGH setting.
30 minutes before you are ready to eat, cook egg noodles according to package directions. Drain, toss with a little butter, and set aside.
Gradually and slowly stir the sour cream into the stroganoff. Serve over buttered noodles and sprinkle with the parsley if desired.
