Ingredients
Instructions
- Peel and wash the onions; cut into chunks.
- Boil the onions until tender; drain off the water.
- Melt the margarine in a skillet and sauté the onions for 3 minutes.
- In a mixing bowl, whisk together eggs, evaporated milk, salt, and pepper.
- Combine the sautéed onions with the egg mixture and shredded cheese.
- Crush the Ritz crackers and sprinkle over the top of the casserole.
- Pour the mixture into a baking dish and bake at 350°F (175°C) for 20 minutes or until golden brown.
Tips & Substitutions
For added flavor, consider using a mix of cheese, such as mozzarella or cheddar, if you can't find Longhorn or Colby. You can substitute half-and-half for the evaporated milk for a creamier texture. If you prefer a crunchier topping, use Panko breadcrumbs instead of Ritz crackers. Make sure to sauté the onions until they are just translucent to preserve their sweetness.
Serving Suggestions
This Vidalia Sweet Onion Casserole makes a wonderful side dish for grilled meats or roasted chicken. It pairs beautifully with a fresh salad, such as Riviera Strawberry Salad, for a balanced meal. Consider serving it alongside a light soup for a comforting dinner or as a hearty vegetarian option at a potluck.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to three days. To reheat, place the casserole in a preheated oven at 350°F (175°C) for about 15-20 minutes, or until heated through. You can also microwave individual portions, but the oven will help retain the crispiness of the topping.
