  • 2-3 whole Vidalia onions or any sweet onion will do
  • 4 tbsp stick unsalted butter
  • Garlic salt to taste
  • Pepper to taste
  • 1 Cup sharp cheddar cheese the better quality, the better taste
  • 1 Cup mozzarella Cheese
  • ½ cup Parmesan cheese
  • Fresh oregano or other herbs for garnish


  • Using non-stick cooking spray, prepare a 9x13 baking dish. 
  • Heat over to 350
  • Slice the Vidalia onions in 1/4 to 1/2 inch slices and separate the rings. 
  • Lay the rings in the prepared baking dish
  • Sprinkle the onion rings with garlic salt (about 1 tsp), pepper (about 1/2 tsp).
  • Cut the butter into pats and place around the dish on top of the onions.  
  • Spread the cheddar and mozzarella cheeses on top of the onions and then top with the grated parmesan cheese.
  • Bake at 350 uncovered for 30 minutes or until bubbly and the cheese has started to brown (browned cheese bits is one of the best parts!)
  • Remove from the oven, allow to cool for a few minutes, garnish with some fresh herbs (oregano, chives, thyme all work well)  and then serve. 



  • 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
