Ingredients

  • 3 large sweet onions (such as Vidalia or Walla Walla), sliced into ¼-inch thick rings
  • 1 ½ cups shredded cheese (a mix of cheddar, mozzarella, and Parmesan works great)
  • 1 cup heavy cream
  • ¼ cup unsalted butter, cut into small cubes
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ cup crushed Ritz crackers (optional, for a crunchy topping)
  • Fresh parsley or chives for garnish (optional)

Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray.

2. Prepare the Onions

Peel the onions and slice them into rings about ¼-inch thick. Separate the rings and arrange them in the prepared baking dish, overlapping slightly.

3. Layer the Ingredients

  • Sprinkle the garlic powder, salt, and black pepper evenly over the onion rings.
  • Pour the heavy cream over the onions, making sure it covers them well.
  • Scatter the butter cubes over the top of the onions.
  • Sprinkle the shredded cheese generously over the entire dish, ensuring the onions are fully covered.

4. Add the Crumb Topping (Optional)

For a crunchy, buttery topping, sprinkle the crushed Ritz crackers evenly over the cheese.

5. Bake to Perfection

Place the baking dish in the oven and bake for 25-30 minutes, or until the onions are tender, the cheese is bubbly, and the top is golden brown.

6. Garnish and Serve

Once baked, remove the dish from the oven and let it cool for a few minutes. Garnish with fresh parsley or chives if desired. Serve warm and enjoy!

Tips for Success

  • Choose Sweet Onions: Vidalia or Walla Walla onions are ideal for their mild, sweet flavor.
  • Don’t Overlap Too Much: Arrange the onion rings in a single layer with slight overlap for even cooking.
  • Use Room Temperature Cream: This helps the dish bake more evenly.
  • Customize the Cheese: Experiment with different cheese blends like pepper jack, Gouda, or smoked cheddar for unique flavors.

Variations and Add-Ons

This recipe is super versatile! Here are some fun ways to customize it:

  • Add Bacon: Sprinkle cooked, crumbled bacon over the top before baking for a smoky twist.
  • Spice It Up: Add a pinch of cayenne pepper or red pepper flakes for a little heat.
  • Herbaceous Touch: Mix in fresh thyme, rosemary, or oregano for an herby flavor.
  • Vegetarian Option: Skip the Ritz crackers or use a vegetarian-friendly alternative for the topping.
