how to make Tennessee Onions

Preheat the oven and get a baking dish ready.
Slice sweet onions into rings and arrange them in the dish.
Pour melted butter over the onions and add simple seasonings.
Mix the cheeses and spread them over the onions.
Bake covered first, then uncover to brown the top.
Let cool a few minutes and serve warm.

Ingredients :

3 large sweet onions (such as Vidalia, sliced into ¼-inch rings)
4 tablespoons unsalted butter (melted)
1 cup sharp cheddar cheese (shredded)
1 cup Monterey Jack cheese (shredded)
½ cup Parmesan cheese (grated)
½ teaspoon garlic powder
½ teaspoon Italian seasoning (or dried thyme/oregano blend)
¼ teaspoon paprika
Pinch of salt and black pepper (to taste)

Directions :

Prep the oven: Preheat to 375°F (190°C). Lightly butter or spray a 9×13-inch baking dish.
Layer onions: Arrange the sliced onion rings evenly in the dish, spreading them out so they overlap slightly.
Season & drizzle: Pour melted butter over the onions. Sprinkle with garlic powder, Italian seasoning, paprika, salt, and pepper.
Add cheese: Mix the three cheeses together in a bowl, then scatter them generously over the onions.
Bake: Cover loosely with foil and bake for 30 minutes. Remove the foil and continue baking for 15–20 minutes, until the top is golden and bubbly.
Serve: Let cool for 5 minutes before serving. This dish works great as a side for steak, chicken, or barbecue.

how to serve Tennessee Onions

Serve warm as a side dish. They go well with grilled meats, roasted chicken, or a plate of barbecue. You can also spoon them over toasted bread for a simple open-faced snack.

how to store Tennessee Onions

Cool to room temperature, then cover and store in the fridge for up to 4 days. Reheat in the oven at 350°F (175°C) until warmed through to keep the top crisp. For longer storage, freeze in a sealed container for up to 2 months and thaw in the fridge before reheating.

tips to make Tennessee Onions

Slice onions evenly so they cook the same.
Use sweet onions for milder flavor.
Mix cheeses well so the melt is even.
Cover while baking first to steam the onions, then uncover to brown.
Let the dish rest a few minutes before serving so it holds together.

variation (if any)

Add cooked bacon bits between the layers for a smoky touch.
Use pepper jack instead of Monterey Jack for a spicy kick.
Stir in a tablespoon of Dijon mustard to the butter for extra tang.
Add a sprig of fresh thyme or chopped rosemary for herb flavor.
