Ingredients
 

Main Ingredients

  • 2 tbsp unsalted butter
  • 1 tbsp olive oil
  • 3.5 cup yellow onions, thinly sliced
  • 0.75 tsp kosher salt
  • 0.5 tsp granulated sugar
  • 2 tsp minced garlic
  • 1 tsp fresh thyme, chopped
  • 0.25 cup beef broth
  • 1.25 lb ground pork sausage
  • 1 tbsp Dijon mustard
  • 1.5 tsp Worcestershire sauce
  • 0.5 cup dry breadcrumbs
  • 0.75 tsp ground black pepper
  • 1 cup Gruyère cheese, shredded
  • 1 tbsp all-purpose flour for dusting
  • 18 oz puff pastry thawed
  • 2 tbsp milk for brushing
  • 1 tsp sesame seeds optional

Instructions

Preparation Steps

  • Melt butter with oil in a skillet over medium heat.
  • Add onions, salt, and sugar. Cook, stirring often, until deep golden, 12–15 minutes.
  • Stir in garlic and thyme for 1 minute. Deglaze with beef broth, scraping up browned bits. Cool completely.
  • Heat oven to 400°F. Line a baking sheet with parchment.
  • Combine sausage, Dijon, Worcestershire, breadcrumbs, pepper, and half the cheese. Fold in cooled onions.
  • Dust the counter with flour. Roll puff pastry into two rectangles, about 10×12 inches each.
  • Shape sausage filling into two even logs. Place along one long edge of each pastry. Brush edges with milk.
  • Roll up tightly, seam-side down. Pinch to seal. Chill 10 minutes if dough feels soft.
  • Cut each log into 6 pieces. Arrange on the sheet. Brush tops with milk.
  • Sprinkle with sesame seeds and remaining cheese. Slash tops to vent.
  • Bake until puffed and deeply golden, 20–24 minutes. Rest 5 minutes before serving.

Notes

Swap Gruyère for sharp white cheddar, or add a touch of grainy mustard for dipping. To make ahead, assemble and freeze unbaked rolls on a sheet pan, then store in a freezer bag; bake from frozen, adding 5–8 minutes.
