Ingredients:
- 4 large onions (preferably yellow or sweet onions)
- 2 cups shredded mozzarella cheese
- 1 cup grated Parmesan cheese
- 1/2 cup breadcrumbs (preferably Italian seasoned)
- 1/4 cup olive oil
- 2 cloves garlic, minced
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- Salt and pepper to taste
- Fresh parsley, chopped (for garnish)
Preparing the Onions
First things first, lets get those onions ready. I love using sweet onions for this dish because they add a lovely flavor, but yellow onions work just as well.
- Peel the onions and slice them in half from top to bottom.
- Now, slice each half into thin half-moons, about 1/4 inch thick. The thinner the slices, the better they will caramelize.
- In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil is hot, add the sliced onions.
- Stir the onions occasionally, allowing them to cook down and caramelize. This should take about 15-20 minutes. You want them to be soft and golden brown. If they start to stick, add a splash of water to deglaze the pan.
- Once the onions are caramelized, add the minced garlic, oregano, basil, salt, and pepper. Stir everything together and cook for an additional 2-3 minutes until the garlic is fragrant.
- Remove the skillet from heat and set the caramelized onions aside to cool slightly.
Preparing the Cheese Mixture
While the onions are cooling, lets prepare the cheesy goodness that will complement our onions perfectly.
- In a large mixing bowl, combine the shredded mozzarella cheese and grated Parmesan cheese. I love the combination of these two cheeses because the mozzarella melts beautifully while the Parmesan adds a nice sharpness.
- Add the breadcrumbs to the cheese mixture. This will help to bind everything together and give it a nice texture.
- Drizzle in the remaining olive oil (about 2 tablespoons) and mix everything together until well combined. You want the mixture to be moist but not overly wet.
- Once the onions have cooled slightly, fold them into the cheese mixture. Make sure everything is evenly distributed. This is where the magic happens!
Assembling the Dish
Now that we have our delicious onion and cheese mixture ready, its time to assemble the dish.
- Preheat your oven to 375°F (190°C). This will ensure that our dish bakes evenly and gets that lovely golden crust.
- Grease a baking dish (about 9×13 inches) with a little olive oil or cooking spray to prevent sticking.
- Transfer the onion and cheese mixture into the greased baking dish, spreading it out evenly. Use a spatula to press it down gently, ensuring its compact.
- For an extra touch, sprinkle a little more grated Parmesan cheese on top. This will create a beautiful crust as it bakes.
Cooking Process
Now its time to bake our dish to perfection!
- Place the baking dish in the preheated oven and bake for about 25-30 minutes. You want the top to be golden brown and bubbly.
- After 25 minutes, check on the dish. If its not quite golden enough, you can broil it for an additional 2-3 minutes. Just keep a close eye on it to prevent burning!
- Once its done, remove the dish from the oven and let it cool for about 5-10 minutes. This will help it set a little and make it easier to serve.
Serving the Dish
Now comes the best partserving and enjoying this delicious onion and mozzarella dish!
- Using a spatula, cut into squares and serve warm. I love to garnish with freshly chopped parsley for a pop of color and
