Ingredients
For the Pinwheels
- 1 sheet (10 ounces) frozen puff pastry, thawed
- 2 large yellow onions, thinly sliced
- 2 tablespoons olive oil
- 1 teaspoon brown sugar
- 1/2 teaspoon salt, divided
- 1/4 teaspoon black pepper
- 4 ounces cream cheese, softened
- 1/2 cup shredded Gruyere cheese
- 1/4 cup grated Parmesan cheese
- 1 teaspoon fresh thyme leaves, chopped
- 1 large egg, beaten

How to Make Caramelized Onion Cheese Pinwheels
Step 1: Caramelize Onions
Heat the olive oil in a large skillet over medium-low heat. Add the thinly sliced yellow onions, 1/4 teaspoon salt, and black pepper. Cook, stirring occasionally, for about 30-40 minutes until the onions are deeply golden brown and very soft. Stir in the brown sugar during the last 5 minutes of cooking. Remove from heat and let cool completely.
Step 2: Prepare Filling
In a medium bowl, combine the softened cream cheese, shredded Gruyere cheese, grated Parmesan cheese, remaining 1/4 teaspoon salt, and chopped fresh thyme. Mix until all ingredients are well combined and smooth.
Step 3: Assemble Pinwheels
Lightly flour a clean surface. Carefully unroll the thawed puff pastry sheet. Evenly spread the cream cheese mixture over the entire surface of the pastry, leaving a 1/2-inch border along one of the long edges. Evenly sprinkle the cooled caramelized onions over the cream cheese mixture.
Step 4: Roll and Slice
Starting from the long edge opposite the 1/2-inch border, carefully roll the pastry into a tight log. Use a sharp knife to slice the log into 8 equal pinwheels, each about 1-inch thick.
Step 5: Bake
Preheat your oven to 400°F. Line a 9×13 inch baking pan with parchment paper. Arrange the pinwheels in the prepared baking pan, leaving a little space between each one. Brush the tops and sides of the pinwheels with the beaten egg.
Step 6: Bake
Bake for about 25-30 minutes or until the pastry is puffed, golden brown, and the cheese is bubbly and melted. Serve warm.
