These sausage rolls combine caramelized onions, savory sausage, and flaky puff pastry for a quick, comforting snack or appetizer that’s crispy and full of flavor.

Ingredients

Scale
  • 2 sheets frozen puff pastry, thawed
  • 1 pound (450g) ground pork sausage (spicy Italian or mild)
  • 2 medium yellow onions, thinly sliced
  • 2 tablespoons butter
  • 2 garlic cloves, minced
  • 1 teaspoon fresh thyme, chopped (optional)
  • Salt to taste
  • Black pepper to taste
  • 1 large egg, beaten
  • ยฝ cup (about 50g) grated sharp cheddar or Gruyere cheese (optional)

Instructions

  1. Heat butter in a large skillet over medium-low heat. Add sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for about 25 minutes until soft, golden, and sweet-smelling.
  2. Add minced garlic and thyme in the last 5 minutes of cooking. Watch closely to avoid burning.
  3. Increase heat to medium. Crumble ground sausage into the skillet with onions. Brown thoroughly, breaking up with a spoon, about 7-8 minutes until no pink remains. Season with pepper and additional salt if needed. Remove from heat and let cool slightly.
  4. Preheat oven to 400ยฐF (200ยฐC). Line a baking sheet with parchment paper.
  5. Unfold one puff pastry sheet on a lightly floured surface. Roll gently to smooth creases. Spread half of the sausage and onion mixture evenly along one long edge, leaving a 1-inch border. Sprinkle cheese over filling if using.
  6. Roll pastry over filling to form a log. Press edges to seal, using a little water if needed. Slice into 8 equal pieces and place cut side down on baking sheet. Repeat with second pastry sheet and remaining filling.
  7. Brush each roll generously with beaten egg. Make a small slit on top of each roll to allow steam to escape.
  8. Bake for 20-25 minutes until puffed and golden brown. Keep an eye near the end to avoid burning.
  9. Remove from oven and let rest for 5 minutes before serving.

Notes

Caramelize onions slowly over low heat to avoid burning. Let sausage mixture cool before adding to pastry to prevent sogginess. Use egg wash for a golden, shiny crust. Chill puff pastry sheets if kitchen is warm for easier handling. Baking on parchment paper and a light-colored baking sheet helps even browning. Rolls can be frozen unbaked and baked from frozen with extra baking time.
