Sweet Onion Casserole

I recently discovered this Onion Casserole Recipe.
I like Onions and any recipe using them. I have an Onion Cookbook filled with incredible recipes. This is a great side dish.
It's easy and delicious.
I'll make it for Thanksgiving.

Here's what you'll need:
Preheat the oven to 350 degrees.
1 - 9" X 13" Glass Casserole Pan, sprayed well with Vegetable Cooking Spray. I use a Cast Iron Enamel Gratin Dish.

3 Vidalia Onions sliced 1/2" thick and separate the rings.
8 TBS Butter, sliced into individual TBS.
1 tsp Garlic Salt
Fresh Ground Black Pepper to taste.
1 C Shredded Sharp Cheddar Cheese.
1 C Shredded Mozzarella Cheese
1/2 C Grated Parmesan Cheese
1 TBS Fresh Chopped Thyme Leaves.

In the Casserole Pan:
Onion Rings, evenly distributed.
Sprinkle evenly with Garlic Salt.
Sprinkle evenly with Black Pepper to taste.
Butter, evenly distributed over the Onion Rings.
Sprinkle evenly with Cheddar Cheese.
Sprinkle evenly with Mozzarella Cheese.
Sprinkle evenly with Parmesan Cheese.

Bake uncovered 30 minutes.
Sprinkle evenly with Thyme just prior to serving.
Serve Hot.

Enjoy!
Peace in the Kitchen!
