Step‑by‑Step Instructions for Tennessee Onions

Step 1: Prepare Onions
Begin by peeling your sweet onions (Vidalia or yellow) and slicing them into thick rings, approximately ½ inch wide. This thickness ensures the onions maintain their structure while caramelizing beautifully. Arrange the onion rings on a clean cutting board and take a moment to admire their fresh, glossy appearance before moving on to the next step.

Step 2: Preheat Oven
Preheat your oven to 375°F (190°C) and grab a 9×13-inch casserole dish. Lightly coat the bottom of the dish with butter to prevent sticking and to add extra richness to your Tennessee Onions. As the oven warms, the savory aroma will begin to fill your kitchen, heightening the anticipation of this delightful, cheesy dish.

Step 3: Arrange Onions
Carefully lay the sliced onions flat in the greased casserole dish, ensuring they touch but do not stack. This single-layer arrangement allows even baking and caramelization of the onions. You’ll notice the onions glistening as you position them, ready to soak up all the flavor you’ll add next.

Step 4: Season
Sprinkle salt, freshly cracked pepper, and Italian seasoning evenly over the laid onions, imparting a blend of aromatic flavors. Distribute small pats of butter across the top of the onions for additional richness. The seasoning will enhance the natural sweetness of the onions, making your Tennessee Onions incredibly satisfying.

Step 5: Layer Cheeses
Start layering the cheeses over the seasoned onions, beginning with a generous amount of shredded mozzarella for that gooey base. Follow with sliced provolone, evenly distributing it for a creamy depth. Finally, top the dish with a generous sprinkle of grated Parmesan, which will bake to a crispy, golden layer that adds texture and flavor to your Tennessee Onions.

Step 6: Bake
Slide the casserole dish into the preheated oven and bake uncovered for 25 to 30 minutes. As the cheese melts and begins to bubble, you’ll see a beautiful golden color forming on top. If you prefer an extra crispy finish, turn on the broiler for an additional 2 minutes, but keep a close eye to prevent burning.

Step 7: Rest
Once baked to perfection, remove your Tennessee Onions from the oven and allow the dish to rest for about 5 minutes. This waiting time enables the cheese to set slightly, making it easier to serve. As you prepare to dish out this comforting side, the tantalizing aroma will surely draw attention from family and friends.

Storage Tips for Tennessee Onions

Fridge: Keep your leftover Tennessee Onions in an airtight container for up to 3 days to maintain freshness and flavor.

Freezer: If you want to store them longer, freeze your Tennessee Onions in an airtight container. They can last up to 3 months; thaw in the fridge before reheating.

Reheating: To enjoy that gooey texture again, reheat in the oven at 350°F (about 10 minutes) instead of the microwave to prevent rubbery cheese.

Expert Tips for Tennessee Onions

Slice Thickness Matters: Ensure onion slices are about ½ inch thick for optimal texture. Thicker slices prevent the onions from becoming mushy while caramelizing.
Cheese Creativity: Feel free to experiment with different cheese blends like sharp cheddar or Monterey Jack. Just keep in mind, the heart of Tennessee Onions is in that gooey, cheesy goodness.
Microwave No-No: Avoid reheating in the microwave; it can make the cheese rubbery. Instead, reheat in the oven at 350°F for about 10 minutes to maintain crispness.
Prep Ahead: Save time by prepping the dish in advance—slice and season the onions, then refrigerate. Just pop it in the oven when you’re ready for comfort food!
Layer Wisely: Arrange onion slices in a single layer to ensure even cooking and caramelization. Stacking them can lead to uneven texture and flavor in your Tennessee Onions.

Make Ahead Options

Making Tennessee Onions ahead of time is a fantastic way to save time on busy weeknights! You can slice and season the sweet onions up to 24 hours in advance, ensuring they stay fresh by covering them tightly and refrigerating. When you’re ready to enjoy this cheesy baked delight, simply layer the cheeses over the prepared onions and bake as directed. For best results, assemble the dish but do not bake it until you’re ready to serve, allowing the flavors to meld while keeping the cheese gooey and delicious. You’ll have a comforting, gourmet side dish with minimal effort, letting you spend more time with family instead of in the kitchen!
