Casserole Filling:
2 tablespoons unsalted butter
4 large Vidalia onions
1 cup crumbled Ritz crackers
3 Eggs
1 1/2 cups (6 ounces) shredded cheddar cheese
1/2 teaspoon salt
1/8 teaspoon pepper
1 (5 ounces) can evaporate milk
Crumb Topping:
3 tablespoons unsalted butter, melted
1 cup crumbled Ritz crackers
HOW TO MAKE SOUTHERN VIDALIA ONION CASSEROLE
Step 1: After slicing the root and stem end of the onions, slice them in half starting from the top. Take the outer skins off. On a cutting board, place the onion halves cut-side-down, then chop the onions into slivers to around 1/4 to 1/2-inch thickness.
Step 2: In a saucepan, place the onions and pour in the water, enough to cover the onions. Bring the liquid to a boil, then decrease the heat. Simmer for about 8 minutes. Drain well when done.
Step 3: With 2 tbsp butter, toss the warm onions.
Step 4: In the meantime, whisk the eggs with the evaporated milk in a large bowl. Stir in the warm cooked onions, cracker crumbs, shredded cheese, salt, and pepper until well mixed.
Step 5: In a greased 9 x 13-inch baking dish, place the onion mixture.
Step 6: Mix the cracker crumbs and melted butter. Evenly sprinkle this over the casserole.
Step 7: Place the baking dish in a 375 degrees oven and bake the casserole for about 45 minutes or until the centre is set and golden brown.
NOTES:
You can use Walla Walla or Texas Spring instead of Vidalias.
For this recipe, you can use regular yellow onions if you don’t mind a more pungent onion flavour.
