Ingredients

• 2 tablespoons olive oil
• 2 large yellow onions, thinly sliced
• 1 teaspoon sugar
• 1 teaspoon sea salt
• ½ teaspoon black pepper
• 1 tablespoon balsamic vinegar (optional)
• 500 g (about 1 lb) pork sausage meat (or sausages, casings removed)
• 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
• 1 teaspoon Dijon mustard
• 100 g (1 cup) grated Gruyère cheese
• 2 sheets frozen puff pastry, thawed
• 1 egg, beaten (for egg wash)
• Sesame seeds or poppy seeds, for topping (optional)

Directions

Prep & Caramelize Onions

1. Heat olive oil in a large skillet over medium-low heat. Add onions, sugar, salt, and pepper. Cook, stirring often, until onions are deeply golden and caramelized, about 25-30 minutes.
2. Optional: Stir in balsamic vinegar in the last 2 minutes for extra flavor. Let cool slightly.

Make the Sausage Filling

3. In a mixing bowl, combine sausage meat, thyme, Dijon mustard, caramelized onions, and grated Gruyère. Mix well until fully combined.

Assemble the Rolls

4. Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
5. Unroll the puff pastry sheets on a lightly floured surface. Cut each sheet in half lengthwise to make 4 rectangles total.
6. Divide the sausage mixture into 4 equal portions. Shape each into a log running down the long edge of each pastry rectangle.
7. Brush the far edge of pastry with egg wash. Roll pastry over sausage, sealing the edge underneath.
8. Cut each long roll into 4-5 smaller pieces (about 2 inches each). Place seam-side down on the baking sheet.

Bake

9. Brush each roll with more egg wash. Sprinkle with sesame seeds or poppy seeds if desired.
10. Bake for 22-25 minutes or until golden brown and puffed up.

Notes

• Chill your assembled rolls in the fridge 10-15 minutes before baking for extra puffy pastry.
• Swap Gruyère for Swiss or any melty cheese you prefer.
• Double the batch and freeze before baking for easy make-ahead entertaining.

Variations

• Vegetarian: Use plant-based sausage and skip the cheese for a dairy-free option.
• Spicy: Add a pinch of chili flakes to the filling or use spicy sausage.
• Mini Bites: Cut rolls smaller for bite-sized finger food appetizers.

Required Equipment

• Sharp knife
• Large skillet
• Mixing bowls
• Baking sheet
• Parchment paper
• Pastry brush

Storage Instructions

• Store cooled sausage rolls in an airtight container in the refrigerator for up to 3 days.
• Freeze unbaked rolls on a tray, then transfer to a bag; bake from frozen, adding 5-7 minutes to bake time.
• Reheat baked rolls in a 350°F (175°C) oven for 8-10 minutes.

Serving Suggestions

• Serve warm with Dijon mustard or tangy chutney for dipping.
• Pair with a crisp green salad for a satisfying lunch.
• Enjoy alongside a cold lager or sparkling apple cider.

Pro Tips

• Don’t rush the caramelizing stage—it’s what gives that sweet, deep onion flavor!
• Seal the pastry edges well to prevent leaking during baking.
• Allow baked rolls to cool slightly before serving for best texture.

FAQ

Can I use store-bought caramelized onions?

Can I make these ahead of time?
