For the Onion Topping:
- 3 tablespoons unsalted butter
- 3 large sweet onions, thinly sliced (about 6 cups)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 2 teaspoons fresh thyme leaves (or 1 teaspoon dried)
For the Creamy Layer:
- 1 cup sour cream
- 1 large egg
- 1 tablespoon all-purpose flour

For the Topping:
- 6 slices bacon, cooked and crumbled (optional)

Instructions
Prepare the Dough:
- In a large bowl, combine 1½ cups of flour, sugar, salt, and yeast.
- Add the warm milk, melted butter, and egg to the dry ingredients. Beat with an electric mixer on medium speed for 3 minutes.
- Gradually stir in remaining flour to form a soft dough.
- Turn onto a floured surface and knead for 5-6 minutes until smooth and elastic.
- Place in a greased bowl, turning once to grease the top. Cover and let rise in a warm place for about 45 minutes, or until doubled in size.
Prepare the Onion Topping:
- While the dough is rising, melt butter in a large skillet over medium-low heat.
- Add the sliced onions, salt, and pepper. Cook slowly, stirring occasionally, for 25-30 minutes until the onions are very soft and caramelized to a golden brown.
- Stir in the thyme leaves. Remove from heat and let cool slightly.
Make the Creamy Layer:
- In a medium bowl, whisk together the sour cream, egg, flour, salt, and pepper until smooth. Set aside.
Assemble the Cake:
- Preheat oven to 375°F (190°C). Grease a 9×13-inch baking pan.
- Punch down the risen dough and roll or press it into the prepared baking pan, creating a slight rim around the edges.
- Spread the sour cream mixture evenly over the dough.
- Distribute the caramelized onions evenly over the sour cream layer.
- Sprinkle with crumbled bacon (if using), Parmesan cheese, and paprika.
Bake:
- Bake in the preheated oven for 25-30 minutes, until the edges are golden brown and the topping is set.
- Let cool for 10 minutes before slicing.
- Garnish with fresh chopped parsley before serving.
Serving Suggestions
Serve warm as a side dish with soups or stews, or as a savory breakfast or brunch option. This onion cake also pairs wonderfully with a simple green salad for a light lunch.
Storage Tips
- Store leftovers covered in the refrigerator for up to 3 days.
- Reheat individual slices in a 325°F oven for about 10 minutes or until warmed through.
- The cake can also be frozen after baking. Cool completely, wrap tightly, and freeze for up to 1 month. Thaw overnight in the refrigerator and reheat before serving.
