Step‑by‑Step Instructions for Tennessee Onions

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grab a 9×13-inch baking dish and lightly grease it with cooking spray or butter. This will ensure that your Tennessee Onions don’t stick and will make serving easier.

Step 2: Prepare the Onions
Slice your sweet onions into rings and layer them evenly in the greased baking dish, carefully separating the rings as you go. A visual cue to look for is a uniform distribution across the bottom of the dish, which allows for even cooking.

Step 3: Season the Onions
Melt butter and drizzle it generously over the onions, making sure they are well-coated. Sprinkle garlic powder, dried thyme, salt, and pepper over the top. Use a spatula to gently toss the onions, ensuring the seasoning is evenly distributed.

Step 4: Add the Cheese Layers
Now it’s time to layer on the cheeses. Spread the cheddar, Monterey Jack, and Parmesan cheeses over the seasoned onions, ensuring every bit is covered with a glorious cheesy layer. The visual should be a sea of golden goodness ready to melt together beautifully.

Step 5: Bake Covered
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 25 minutes. The foil traps moisture, promoting tenderness in the onions while the cheese begins to melt.

Step 6: Bake Uncovered
After 25 minutes, carefully remove the foil, taking care to avoid steam. Increase the baking time by an additional 10 minutes, allowing the cheese to bubble and turn golden brown. The visual cue for doneness is a beautifully browned top that might have some bubbly spots.

Step 7: Cool and Serve
Once finished, carefully remove the dish from the oven and allow it to cool for a few minutes. This brief cooling period enhances the flavors and makes it easier to serve your scrumptious Tennessee Onions. Enjoy the delightful aroma as you prepare to dig in!
