Ingredients & Instructions
Ingredients
- 3 large sweet onions (such as Vidalia), sliced into ½-inch rings
- 1 ½ cups shredded cheddar cheese
- 1 cup shredded Monterey Jack cheese
- ½ cup grated Parmesan cheese
- 4 tablespoons unsalted butter, melted
- 1 teaspoon garlic powder
- ½ teaspoon dried thyme
- ½ teaspoon salt
- ¼ teaspoon black pepper
Step-by-Step Instructions
1. Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking and make cleanup easier.
2. Arrange the Onions
Slice the sweet onions into ½-inch rings and arrange them in an even layer in the baking dish. Take care to separate the rings slightly so that they cook evenly and allow the flavors to meld beautifully with the cheese and seasonings.
3. Season and Butter
Drizzle the melted butter evenly over the onions. Sprinkle with garlic powder, dried thyme, salt, and black pepper, ensuring each onion ring receives a little of the flavorful seasoning.
Pro Tip: Toss the onions gently with the seasonings to coat them evenly without breaking the rings.
4. Add the Cheeses
Layer the cheddar, Monterey Jack, and Parmesan evenly over the onions. The combination of cheeses ensures a perfect balance of sharp, creamy, and nutty flavors that complement the natural sweetness of the onions.
5. Bake
Cover the dish with foil and bake for 25 minutes. This initial covered bake allows the onions to soften without burning the cheese. After 25 minutes, remove the foil and continue baking for an additional 10 minutes, or until the cheese is golden and bubbly.
6. Serve
Let the dish cool slightly before serving to allow the cheese to set a bit, making it easier to serve. Enjoy this decadent side dish alongside your favorite meats or as part of a festive spread.
Cooking Tips & Variations
- Cheese Variations: Swap Monterey Jack for mozzarella or gouda for a different flavor profile.
- Add Herbs: Fresh thyme or rosemary can be added before baking for a fragrant twist.
- Spice It Up: A pinch of red pepper flakes can add a subtle heat to balance the sweetness of the onions.
- Presentation: Serve directly from the baking dish for rustic charm or transfer to a platter for a fancier presentation.
- Make Ahead: Assemble the dish a few hours ahead, cover, and refrigerate. Bake just before serving for convenience.
Storage & Serving Suggestions
- Refrigerator: Store leftovers in an airtight container for up to 3 days. Reheat gently in the oven to maintain the cheesy texture.
- Serving Ideas: Pair Tennessee Onions with roasted chicken, grilled steak, baked ham, or even alongside mashed potatoes for a comforting meal. They also work beautifully as part of a holiday spread.
