Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13 inch baking dish with cooking spray or a little butter.

This prevents the onions from sticking.

---

2. Prepare the Onions

Peel the onions and slice them into ¼-inch thick rings.

Separate the rings slightly so they cook evenly.

Small tip: Try to keep the rings fairly thick so they stay tender while baking.

---

3. Arrange the Onions

Place the onion rings evenly in the baking dish.

Spread them out so they cover the bottom of the dish in one or two layers.

---

4. Add Butter and Seasoning

Drizzle the melted butter evenly over the onions.

Sprinkle garlic powder, salt, black pepper, and paprika on top.

The butter helps soften the onions and adds rich flavor.

---

5. Add the Cheese

Sprinkle the mozzarella, cheddar, and Parmesan cheese evenly over the onions.

Make sure the cheese covers most of the onions.

This will create a delicious golden topping when baked.

Small tip: Mixing the cheeses together before sprinkling can help distribute them evenly.

---

6. Bake the Dish

Place the baking dish in the oven.

Bake for 30–35 minutes.

The onions should become soft, and the cheese should melt and turn slightly golden.

---

7. Broil for Extra Color (Optional)

If you like a crispy top, turn on the broiler for the last 2–3 minutes.

Watch carefully so the cheese does not burn.

---

8. Garnish and Serve

Remove the dish from the oven and allow it to cool for about 5 minutes.

Sprinkle fresh parsley on top if desired.

Serve warm.

Tips & Variations
