What’s a vidalia onion?

Can I use another type of onion in this recipe?

If you can’t find vidalia onions in your area, sweet onions are a good substitute. However, using a strong onion will not produce the same results

    Loved this recipe. Made it for Thanksgiving and it added an extra special touch to the typical fixin’s. Thank you for this recipe…and your others!

  2. Why is soy sauce added after chesse and half and half? What if it was addd while onions are first sautéing with melted butter.
    This recipe sounds delicious and can’t wait to surprise my family with it .

    1. Great question Catherine! This is a vintage southern recipe and it’s done like this so you really get the taste of the soy sauce on top. I’ve made it the way you are suggesting and it can be done that way too. But, if you really want to taste the soy sauce, that’s why it’s put on top. 🙂
