Delicious onion casserole great for family get together’s or church dinners. Use Vidalia onions if you can get them, but any sweet onion will work well.
3 large Vidalia (or sweet) Onions
1 1/2 cups shredded Swiss cheese
1 1/2 cups shredded Mozzarella cheese
1 cup Duke’s Mayonnaise
Preheat oven to 350F degrees.
Spray a 9”x13” casserole dish with cooking spray. Set aside.
Slice onions into rings.
Layer the onion rings in the casserole dish.
In a large mixing bowl, add the Swiss cheese.
Add the mozzarella cheese.
Add the mayonnaise.
Mix the cheese and mayonnaise together until fully combined.
Spread cheese mixture over the onions.
Bake 30 – 40 minutes or until top is golden brown.
The cheese and mayonnaise will produce a fair amount of oil once baked. Let it cool well before serving and use a slotted spoon so you can let it drain a bit before placing it on your plate.
