This is one of the only steak marinade recipes we ever use! It requires only three ingredients - Italian dressing, A1, and Worcestershire sauce - and makes our steak taste SO amazing! Everyone always asks for this Easy Steak Marinade recipe because it's just that good!!
Place all your ingredients in a gallon bag or tupperware. Mix well.
Add your steak (we prefer Flat Irons because they are tender and fairly inexpensive).
Let marinade for 24-36 hours. You can even do 12 hours if you'd like but I think it's better if it's for at least 24 hours.
Grill and ENJOY!
