Ingredients
Vegetables
- 3-4 sweet onions
Seasonings
- 1 teaspoon garlic powder
- 1/2 teaspoon Italian seasoning
- 1/2 teaspoon salt
- 1/4 teaspoon ground black pepper
Dairy
- 4 tablespoons unsalted butter, sliced thin
- 2 cups shredded cheddar cheese
- 2 cups shredded Italian blend cheese or shredded mozzarella
- 1/2 cup grated parmesan cheese
Instructions
- Preheat the oven: Preheat your oven to 350 degrees F (175 degrees C) and spray a 9 x 13-inch baking dish with non-stick cooking spray to prevent sticking.
- Prepare the onions: Peel off the skins of the sweet onions, then slice them into thin slices about 1/4-inch thick. Separate these slices gently into individual onion rings for layering.
- Layer the onions: Lay the onion rings evenly in the prepared baking dish to form a base layer.
- Season the onions: Evenly sprinkle the garlic powder, Italian seasoning, salt, and ground black pepper over the onion rings to infuse them with flavor.
- Add butter: Distribute the thinly sliced pats of unsalted butter over the seasoned onions to add richness and help with melting.
- Add the cheese layers: Spread the shredded cheddar cheese evenly over the onions, followed by the Italian blend cheese (or shredded mozzarella if preferred), and finally sprinkle the grated Parmesan cheese on top to form a cheesy crust.
- Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is fully melted and golden brown on top.
- Serve warm: Remove from the oven and serve the Tennessee Onions warm as a delicious side dish or appetizer.
Notes
- For a sharper flavor, opt for aged cheddar cheese.
- You can substitute Italian blend cheese with shredded mozzarella if preferred.
- Use non-stick spray or a little oil to prevent onions from sticking to the baking dish.
- Adjust seasoning according to taste preference.
- This dish pairs well with grilled meats or as a hearty vegetarian side.
