This Crock Pot Mongolian Beef recipe is perfect. It has the perfect combination of flavors that all come together to make a delicious Asian sauce.

The thinly sliced flank steak simmers and slowly cooks together until the beef is so tender it will fall apart with each exquisite bite.

Oh la la this Crock Pot Mongolian Beef is oh so good! Why bother with take-out when you can make your favorite Chinese food at home?

Mongolian Beef is made with flank steak. And flank steak is one of the tenderest cuts of beef if cut correctly and cooked properly.

When slicing flank steak to make this Crock Pot Mongolian Beef recipe or any other recipe that calls for sliced flank steak you must cut it across the grain.

What exactly does slicing across the grain mean?

If you look down on a piece of flank steak you will notice there are lines running across it.

Those lines are what is known as the grain. Cutting across the grain when slicing flank steak is what makes flank steak tender.

When you slow cook flank steak it cooks up so tender that it almost melts in your mouth.

What is a good substitute for Flank Steak?

Mongolian Beef is traditionally made with thinly sliced flank steak.

If the price of flank steak turns you off you can substitute skirt steak for flank steak in any recipe.

In a crunch, you could also use very thinly sliced London broil as long as it is sliced against the grain.

Prices of meats vary considerably depending on where you live.

You might be able to find flank steak at a decent price where you live.

If that is not the case there are two other cuts of beef that are an option for this Crock Pot Mongolian Beef recipe.

Like Crock Pot Beef and Broccoli or Crock Pot Teriyaki Chicken to name a few.

If you like sticky chicken then this Crock Pot Honey Garlic Chicken Breasts is another option.

    It seems like 1 cup of soy sauce would be too much salt.
