Step‑by‑Step Instructions for Tennessee Onions

Step 1: Preheat and Prepare the Baking Dish
Begin by preheating your oven to 375°F (190°C). While it’s heating, generously grease a 9×13-inch baking dish with unsalted butter or cooking spray. This step ensures the Tennessee Onions won’t stick and allows for even cooking. The aroma of the warm butter will set the stage for this comforting dish.

Step 2: Slice and Layer the Onions
Peel and slice your large sweet onions into uniform rings, aiming for about ¼-inch thickness. Layer the onion rings evenly in the prepared baking dish, ensuring they are slightly separated to promote even cooking. A beautifully arranged layer not only looks enticing but allows the flavors to meld beautifully in the upcoming steps.

Step 3: Drizzle and Season
Melt a tablespoon of unsalted butter and drizzle it evenly over the layered onions, ensuring each ring is coated in rich flavor. Next, sprinkle the garlic powder, dried thyme, salt, and black pepper over the onions. This seasoning blend enhances the natural sweetness of the onions, making them irresistible and aromatic.

Step 4: Add the Cheesy Toppings
Evenly distribute the shredded cheddar, Monterey Jack, and grated Parmesan cheeses over the seasoned onions. Make sure every bite of your Tennessee Onions will be oozing with cheesy goodness. The combination of these cheeses creates a rich, creamy topping that will bubble and brown perfectly in the oven.

Step 5: Bake with Care
Cover the baking dish with aluminum foil, ensuring it is tightly sealed to trap in moisture. Bake the Tennessee Onions in the preheated oven for 25 minutes. This initial covered bake helps cook the onions through, allowing them to become tender and absorb all the delightful flavors.

Step 6: Uncover and Finish Baking
After the first 25 minutes, carefully remove the foil to reveal the cheesy goodness. Return the dish to the oven and bake uncovered for an additional 10 minutes, or until the cheese is golden and bubbling. This final step creates a beautiful, crispy cheese layer that is mouthwatering and inviting.

Step 7: Cool and Serve
Once out of the oven, let the Tennessee Onions cool for a few minutes. This slight cooling period allows the flavors to settle and prevents burns from the hot cheese. Serve warm as a side dish or as a delightful snack, and watch everyone indulge in this cheesy comfort food!
