My grandma brought this recipe with her when she emigrated from Italy as a young wife and mother. It is still a family favorite. —Janet Eddy, Stockton, California

Ingredients

  • 2 tablespoons olive oil
  • 2 cups sliced onion
  • 1 teaspoon salt, divided
  • 1/4 teaspoon pepper
  • 2 cups all-purpose flour
  • 3 teaspoons baking powder
  • 5 tablespoons shortening
  • 2/3 cup 2% milk
  • 1 large egg, room temperature
  • 3/4 cup sour cream

Directions

  1. Preheat oven to 400°. In a large skillet, heat oil over medium heat. Add onion; cook and stir until softened, 8-10 minutes. Reduce heat to medium-low; cook until deep golden brown, 30-40 minutes, stirring occasionally. Stir in 1/2 teaspoon salt and the pepper.
  2. Meanwhile, in a large bowl, combine flour, baking powder and remaining 1/2 teaspoon salt. Cut in shortening until mixture resembles coarse crumbs. Stir in milk just until moistened. Press into a greased 9-in. square baking pan; top with onion.
  3. Combine egg and sour cream; spread over onion layer. Bake until golden brown, 35-40 minutes. Cut into squares. Serve warm.
