Place the beef cubes into the Crockpot and season them with salt and pepper.

In a separate bowl, combine the dry onion soup mix, cream of mushroom soup, beef broth, and mushrooms. Stir the ingredients together until well combined.

Pour the mixed soup mixture over the seasoned beef in the Crockpot.

Stir everything to combine.

Cook the mixture on the low setting of the Crockpot for 6-8 hours, allowing the flavors to meld and the beef to become tender.

Serve the beef and sauce over your choice of egg noodles or rice.
