Heat the olive oil in a large pan or skillet over medium-high heat. Give the oil a few minutes to heat up and then add the diced onions and mushrooms. Cook for about 5 minutes until tender.
Add the beef to the skillet and continue cooking for about 3-5 minutes, or until the beef is lightly browned.
Add the beef and veggie mixture to your slow cooker along with the beef broth, apple cider vinegar, worcestershire sauce, dijon mustard, garlic powder, salt, and pepper.
Cook the stroganoff on high for 4 hours or low for 6 hours. Near the end of the cook time, cook the egg noodles according to the package directions.
Whisk the cornstarch together with a splash of water. Whisk the cornstarch slurry into the stroganoff mixture. Continue stirring until it is blended and cook in crockpot until it has thickened slightly.
Serve your beef stroganoff over the egg noodles and enjoy!
Any mushroom variety works well in this recipe - both brown and white mushrooms deliver excellent flavor results.
Yellow onions can replace white onions if you prefer a subtly sweeter taste profile.
