You Must Know

Slow cooking allows the beef to become melt-in-your-mouth tender while absorbing the sauce. Be careful not to overcook the noodles—add them at the end to prevent them from becoming mushy. Adjust the sauce thickness by simmering it on the stove if it’s too thin.

Storage Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove, adding a splash of broth or water to loosen the sauce if necessary.

Ingredient Substitutions

  • Substitute beef with chicken, pork, or tofu for variation.
