WHAT ARE TENNESSEE ONIONS?
Good question! Sweet Onions like Tennessee Onions are baked Vidalia (or other sweet onions) Onions with butter, cheese, garlic and various herbs.
This dish of Tennessee Onions are a creation using sweet vidalia onions from the recipe of a great grandmother of a good friend of mine. I have no idea why she called this vidalia onion casserole Tennessee Onions.
Vidalia onions come from Georgia, not Tennessee! Who knows – let’s just roll with it – OK?

IS A VIDALIA ONION A SWEET ONION?
Yes, vidalia onions are sweet onions. If you can’t find Vidalias try substituting Cipollini onions, Texas Sweet or other sweet onions.
WHERE ARE VIDALIA ONIONS GROWN?
According to my research, REAL vidalia onions are grown in Georgia!
HOW DO I STORE VIDALIA ONIONS?
Store Vidalia onions (and all onions) in a cool dry dark place. If you happen to have an old pair of panty hose, you can drop a Vidalia down into the foot, tie a knot, drop another in and so on.
Just cut the bottom one off as you need an onion! This works GREAT!
WHEN ARE VIDALIA ONIONS IN SEASON?
Vidalia Onions are in season in the summer time. You will be able to find other types of sweet onions all year long.
TIPS AND TRICKS FOR Tennessee Onions
- Serve Tennessee Onions over hamburgers, over steak, as a side dish at your cookout or even as a “burger option” for your vegetarian friends.
- Cut the sweet onions in even thicknesses and separate out the rings
- Cut the sweet onions about 1/2 inch thick
- Use Vidalia Onions when available. Texas Sweets will do as well. Any sweet onion will do in a pinch but Vidalias are the best.
- These Tennessee Onions do not make a custard pie like filling, they simply make baked onions with a cheesy topping – YUM!
- Use the best quality cheese that you can afford for this – it makes a difference.
- Check to see if it needs salt before adding any, cheese and garlic salt are both salty already
EQUIPMENT I USE WHEN MAKING TENNESSEE ONIONS
I don’t really use anything special, but if you are taking this to a cookout or a church dinner, it is always nice to have a good portable casserole dish. I bought this one last year and have really enjoyed the simple snap on lid that makes taking it places super nice!

A VERSE TO SHARE
“Wonder what the Bible says about onions?” is what I looked up in curiosity. Did you know that one of the things that the Israelites cried over while they were wandering in the dessert was onions? I can sympathize, I would miss them too.
In Numbers 11, God becomes angry with the people for complaining. After All, they are safe in the desert and He knows that everything is going to be OK in the end. The Lord has supplied the people with Manna every single day.
I wonder what Manna tasted like?
That’s beside the point. Anyway, the people cried and complained and God became angry and a fire broke out burning part of their camp. Moses had to pray an interventional prayer and the fired died down.
This story reminds me so much of when my own children were small and trying to deal with them. I’m sure you understand if you have dealt with children. Let’s forego the gory details and just say, “I relate”.
I would love to hear your thoughts on this verse or on the recipe. You can write me directly at wendi(at sign)loavesanddishes.net or just leave a comment here and I’ll comment back!

I am thankful that you shared your recipe with us. These are absolutely delicious I usually around 500 pounds of caramelized vidalia onions which I freeze and and then I take around 150 pounds I dehydrate them. The first thing we have is a bowl of French onion soup.
