Prepare the Onions for Baking
To unlock the full flavor of your Tennessee Onions, begin by creating a harmonious blend of spices. In a large bowl, toss your sliced onions with kosher salt, dry mustard powder, garlic powder, smoked paprika, and the cayenne pepper if you’re feeling adventurous. This combination isn’t just seasoning—it enhances the sweet, natural flavor of the onions while adding a bit of warmth.
Layer the Ingredients in the Baking Dish
Next, take a baking dish and lightly coat it with cooking spray to prevent your casserole from sticking. Layer half of the seasoned onion rings evenly across the bottom. This method not only keeps the layers distinct but ensures even cooking. Sprinkle two ounces each of the mild cheddar and smoked Gouda cheese over the onions, setting the stage for a luscious, cheesy experience.
Continue by layering the remaining onion rings, followed by the rest of the cheese and finishing with the grated Parmesan. For a touch of richness, scatter the diced butter on top.
Bake the Casserole to Perfection
Cover your baking dish with aluminum foil and place it in a preheated oven at 350ºF. Bake for about 45 minutes, allowing the onions to soften and the dish to bubble up invitingly. After that, uncover and bake for another 30 minutes or so, until the top is beautifully golden and crispy. The cheese should be melted, adding an irresistible gooey texture.
Garnish and Serve
Once your Tennessee Onions are out of the oven, sprinkle them with finely chopped parsley for a touch of freshness and color. This step elevates the dish both visually and flavor-wise. Serve the casserole warm, and watch as your friends and family rave about this delightful veggie dish!
Delicious, comforting, and perfect for gatherings, this recipe is sure to become a favorite. Don’t forget to explore variations or add your twist to make it your own! For more onion cooking tips, check out resources like the National Onion Association for inspiration.
