Three Cheese And Onion Easter Egg Pie - cooking recipe

Ingredients

1 1/4 cups all-purpose flour
1/2 teaspoon salt
1/2 teaspoon white sugar
1/2 cup cold unsalted butter, cut into small pieces
2 tablespoons ice water, or as needed
1 large yellow onion, sliced
1 (8 ounce) package shredded Cheddar cheese
1/2 cup shredded mozzarella cheese
1/4 cup grated Parmesan cheese
3 hard-boiled eggs, peeled and sliced
1/2 cup half-and-half
freshly ground black pepper to taste
3/4 cup finely crushed buttery round crackers
1/4 cup butter, melted

Preparation

Whisk flour, salt, and sugar in a bowl; work 1/2 cup unsalted butter pieces into dry ingredients with your fingers until flour mixture looks like coarse meal. Mix ice water into dough a little at a time until it just holds together. Form into a ball and press dough down to form a flat disk; wrap in plastic wrap and refrigerate at least 1 hour.
Preheat oven to 350 degrees F (175 degrees C).
Roll dough out to a circle on a floured work surface and fit crust into a 9-inch pie dish; crimp the edges.
Place onion slices into a saucepan, cover with water, and bring to a boil; reduce heat to medium and boil until onion is translucent, about 5 minutes. Drain and cool onion slices; spread into bottom of pie crust and top with Cheddar, mozzarella, and Parmesan cheeses in layers. Spread egg slices over cheese. Pour half-and-half over filling and sprinkle with black pepper.
Mix buttery round cracker crumbs and 1/4 cup melted butter in a bowl; sprinkle crumb mixture evenly over pie.
Bake in the preheated oven until browned, about 40 minutes.
