Tennessee Onions Casserole Recipe: Sweet Onions, 3 Cheeses by 30Seconds Food
The sliced onions are put into a casserole dish and seasoned with garlic salt or garlic powder and black pepper, then dotted with butter and sprinkled with shredded mozzarella and Parmesan cheese. If you use garlic powder, you may want to add a little salt. But be careful because the cheeses are already salty. The onions are baked in the oven for about 30 minutes or until hot, melted and bubbly. Mmm!
