First, matters needing attention:

Beef should choose sirloin steak, beef tenderloin or tender parts suitable for frying. Pickling with seasoning in advance, and then wrapping with a layer of cooking oil can better lock the water, so that it won't be hard to eat. If the baby's chewing ability is really not very good, you can also mash the beef, squeeze out the shape of beef granules and fry it.

Second, prepare ingredients:

Beef, potato, onion, onion, soy sauce.

Third, specific practices:

1, onion and potato are cut into appropriate sizes, and diced beef is marinated evenly with a spoonful of soy sauce, a spoonful of starch and auxiliary cooking oil 10 minute. Pickling beef with soy sauce in advance will be more delicious.

2, a spoonful of soy sauce, a spoonful of oyster sauce, half a spoonful of starch, half a spoonful of water, stir well and make a sauce for later use.

3. Put oil in the pot and beef, stir fry quickly and then remove it for use. The frying time should not be too long, which will affect the taste.

4, pour a little more oil from another pot, add potatoes and fry them on low heat until the surface is slightly burnt, and fry them slowly on low heat. Add onion and stir-fry until fragrant, then add beef and sauce, stir well and take out.
