A "recipe" is a set of instructions that tells you how to make a certain kind of food.The recipe lists the ingredients that you need, then tells you how to cut, combine, and cook it all.
On packaged food, sometimes there are instructions printed on the side of the box or bag. We don't call this a "recipe". We call it "instructions":
I just followed the instructions on the box.
When you want to talk about the food that you made with a recipe, there are different words for different kinds of food: "a dish", "a salad", "a pie", etc.:
