People often ask me to share my go-to recipes, and this is one of them.
Good quality flank steak (I love the Costco cut)
low sodium soy sauce
coarse ground Dijon mustard
1/2 chicken broth
Rub steak with "rub ingredients and marinate for 2-3 hours in a covered container while refrigerated. Pour chicken broth into base on baking pan and bake flank steak in 385 degree oven for 30-40 minutes. Let rest for 10 minutes before cutting so that the juices are contained.
