How to Make Tennessee Onions
-
Preheat oven: Begin by preheating your oven to 350°F (175°C). This ensures a perfectly cooked and bubbling dish when it’s time to bake those delicious layers of goodness!
-
Grease the dish: Generously grease a baking dish with butter or cooking spray. This will prevent those heavenly onions from sticking and help achieve a golden finish.
-
Arrange onions: Layer the thickly sliced sweet onions evenly in the greased dish. Make sure they’re spread out nicely so every bite is packed with flavor!
-
Season and add butter: Sprinkle garlic powder and onion powder over the onions. Dot the top with pieces of unsalted butter, allowing the richness to seep into every layer.
-
Top with cheese: Generously sprinkle the shredded cheddar and mozzarella over the seasoned onions. The cheeses will melt into a gooey layer that’s simply irresistible.
-
Bake blissfully: Cover the dish with aluminum foil and bake for 40 minutes. Then, remove the foil and bake for an additional 15 minutes until the cheese is bubbly and lightly golden.
-
Rest and serve: Allow the dish to rest for about 5 minutes after baking. This will help the layers set slightly, making it easier to serve up those beautiful portions.
Optional: Garnish with fresh herbs like parsley or chives for an extra pop of color.
