Ingredients:
01 – 3 to 4 Vidalia sweet onions, peeled and sliced into 1/4-inch thick rounds, rings kept intact
02 – 4 tablespoons unsalted butter, cut into 8 even pats
03 – 1 teaspoon salt
04 – 1 teaspoon garlic powder
05 – 1/2 teaspoon dried oregano
06 – 1 cup Italian blend cheese, finely shredded (Mozzarella, Parmesan, Romano, Asiago, Provolone)
07 – 1 cup cheddar cheese, finely shredded
08 – 1/2 cup Parmesan cheese, finely shredded
Instructions:
01 – Preheat oven to 350°F. Ensure oven rack is positioned in the center. Lightly coat a 9×13-inch baking dish with non-stick cooking spray for easy release and cleanup.
02 – Peel Vidalia onions and slice crosswise into 1/4-inch thick rounds, ensuring rings remain intact. Evenly lay onion rounds across the base of the prepared dish. Sprinkle evenly with salt, garlic powder, and dried oregano.
03 – Arrange butter pats over the surface of the seasoned onions for even melting and flavor. Evenly sprinkle Italian blend cheese and cheddar cheese over the onions. Top with a final layer of Parmesan cheese.
04 – Place baking dish in oven and bake for 35 to 40 minutes, or until cheese is melted, golden brown, and bubbling, and onions are fork-tender.
05 – Remove from oven and let cool slightly before serving warm.
Notes:
01 – Use Vidalia or other sweet onions for a milder, more caramelized flavor when baked.
