Key Ingredients for Tennessee Onions – The Ultimate Cheesy Side Dish
Here’s what you will need to create the perfect Tennessee Onions:
- 4 large onions, thinly sliced (preferably yellow or sweet onions)
- 2 cups shredded cheddar cheese
- 1 cup heavy cream (for a creamier texture, you can substitute with half-and-half)
- 2 tablespoons butter
- 2 tablespoons olive oil
- Salt and pepper to taste
- Optional: Fresh herbs like thyme or parsley for garnishing
Step-by-Step Instructions
- Prepare the Onions: Begin by thinly slicing the onions. Look for a nice uniform thickness to ensure even cooking.
- Sauté the Onions: In a large skillet over medium heat, combine butter and olive oil. Once hot, add the sliced onions and season them with salt. Cook for about 20-25 minutes, stirring occasionally, until the onions are caramelized and golden brown.
- Add the Cream: Reduce the heat to low and pour in the heavy cream, stirring to coat the onions well. Allow it to simmer for another 5 minutes.
- Layer the Cheese: Preheat your oven to 375°F (190°C). Transfer the onion mixture into a baking dish and sprinkle shredded cheddar cheese evenly on top.
- Bake: Place the dish in the oven and bake for about 15 minutes or until the cheese is melted and bubbly. If you prefer a crispy top, broil it for an extra 2-3 minutes, just until golden.
- Serve and Enjoy: Remove from the oven, garnish with fresh herbs if desired, and serve hot!
