How to Make Tennessee Onions

Slice the Onions: Take 3 large Vidalia onions and slice them into ¼-inch rings. Arrange these rings evenly in your baking dish, slightly overlapping them for a beautiful layered effect.

Drizzle with Butter: Melt some unsalted butter and drizzle it over the onion layers. Sprinkle generously with garlic powder, Italian seasoning, paprika, salt, and black pepper to season the onions perfectly.
-
Mix the Cheeses: In a separate bowl, combine sharp cheddar, Monterey Jack, and grated Parmesan cheese. Once mixed, sprinkle this creamy cheese mixture evenly over the seasoned onions.

Expert Tips for Tennessee Onions

Choose Sweet Onions: Opt for Vidalia onions for their natural sweetness. Substituting with Walla Walla or Maui onions ensures a similar flavor profile.
-
Cheese Layering: Mix cheeses in advance for even melting. The combination of sharp cheddar, Monterey Jack, and Parmesan creates the perfect cheesy topping for Tennessee Onions.

Rest Before Serving: Allow the dish to cool for about 5 minutes before serving. This helps the cheese set and prevents scalding from the hot, melted cheese.
