Description

Tennessee Onions is a comforting baked onion dish featuring sweet onions layered with aromatic seasonings and a luscious blend of cheddar, Italian blend, and parmesan cheeses. Baked to golden perfection, this side dish offers a savory, cheesy flavor perfect for family meals or gatherings.


Ingredients

Vegetables

  • 3-4 sweet onions, sliced into rings

Spices

  • 1 teaspoon garlic powder
  • 1/2 teaspoon Italian seasoning
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground black pepper

Dairy

  • 4 tablespoons unsalted butter
  • 2 cups shredded cheddar cheese
  • 2 cups shredded Italian blend cheese or mozzarella
  • 1/2 cup grated parmesan cheese


Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9 x 13-inch baking dish to prevent sticking and ease cleanup.
  2. Prepare Onions: Peel the sweet onions and slice them into rings. Carefully separate the rings and arrange them evenly in the greased baking dish.
  3. Season: Evenly sprinkle the garlic powder, Italian seasoning, salt, and ground black pepper over the onion rings to infuse them with savory, aromatic flavors.
  4. Add Butter: Place slices of unsalted butter atop the seasoned onion rings, which will melt during baking and add rich flavor.
  5. Add Cheeses: Layer the shredded cheddar cheese, Italian blend cheese or mozzarella, and grated parmesan cheese evenly over the onions and butter, creating a cheesy topping that will melt and brown.
  6. Bake: Place the baking dish in the preheated oven and bake for 25 to 30 minutes, or until the cheese is thoroughly melted and has turned a golden brown color.
  7. Serve: Remove the dish from the oven and serve warm. Enjoy your delicious Tennessee Onions as a side dish or a savory snack!

Notes

  • For a sharper flavor, use sharp cheddar cheese.
  • You can substitute Italian blend cheese with mozzarella if preferred.
  • Adjust seasoning to taste, especially salt, depending on your cheese’s saltiness.
  • Use sweet onions like Vidalia for best flavor balance.
  • Optional: Garnish with fresh parsley or chives before serving for added color and freshness.
