Ingredients
Main ingredients
- 4 large Vidalia onions These sweet onions are the stars of the dish.
- 2 tablespoons unsalted butter For mixing into the onion mixture.
- 3 large eggs Provides structure and richness.
- 5 oz. can evaporated milk Gives creaminess to the casserole.
- 1 cup crumbled Ritz crackers Adds texture.
- 6 oz. shredded cheddar cheese Provides flavorful cheesy goodness.
- 1/2 teaspoon salt To enhance flavor.
- 1/8 teaspoon pepper To season.
- 1 cup crumbled Ritz crackers (for topping) For a crunchy topping.
- 3 tablespoons unsalted butter, melted (for topping) To help stick the topping together.
Instructions
Preparation
- Preheat your oven to 375°F (190°C).
- Slice off the root and stem ends of the Vidalia onions, then cut them in half vertically. Peel each half and chop into slivers about 1/4-inch to 1/2-inch thick.
- In a saucepan, place the chopped onions and cover them with water. Bring to a boil over medium heat and simmer for about 8 minutes until they are tender. Drain thoroughly.
- In a large bowl, toss the warm, drained onions with 2 tablespoons of unsalted butter.
Mixing
- In another large bowl, beat the 3 eggs with the can of evaporated milk until well combined.
- Fold in the cooked onions, crumbled Ritz crackers, shredded cheddar cheese, salt, and pepper, mixing gently until uniformly combined.
Baking
- Prepare a 9x13-inch baking dish by coating it with non-stick spray and transfer the onion mixture into the dish, spreading it out evenly.
- In a small bowl, combine 1 cup of crumbled Ritz crackers with 3 tablespoons of melted butter, stir until fully coated, then sprinkle over the casserole.
- Bake in the preheated oven for about 45 minutes, or until the casserole is set in the middle and has turned a golden brown.
Notes
Taste your Vidalia onions before cooking; if they’re overly sweet, consider adding a pinch of sugar to balance the flavors. You can prepare the casserole ahead of time and store it in the fridge for up to a day before baking. Consider adding chopped bell peppers or spinach for added nutrition.
