Ingredient Notes & Details
Sausage meat
Use high-quality pork sausage for the best flavor. You can also substitute chicken or turkey sausage for a lighter option.
Onions
Yellow onions work best for caramelizing. Cook them slowly to develop that signature French onion depth.
Puff pastry
Store-bought puff pastry is perfect here. Look for all-butter pastry if possible for extra flavor and flakiness.
Butter
Essential for caramelizing the onions properly. It adds richness and enhances the sweetness.
Garlic
Adds depth and complements the sausage beautifully.
Beef broth
Gives that classic French onion soup flavor. You can substitute with chicken broth if needed.
Gruyère cheese (optional)
Adds a creamy, slightly nutty flavor. You can also use mozzarella or cheddar.
Egg wash
A mix of egg and a splash of milk gives that beautiful golden finish.
Fresh thyme (optional)
Adds a subtle herbal note that elevates the entire dish.
Step-by-Step Instructions
Step 1: Caramelize the onions
Slice your onions thinly and cook them in butter over medium-low heat. Stir occasionally for about 25–30 minutes until they become soft, golden, and deeply caramelized.
Step 2: Add flavor layers
Stir in garlic, thyme, and a splash of beef broth. Let it cook until most of the liquid evaporates. This step builds that rich French onion base.
Step 3: Prepare the sausage filling
In a bowl, mix the sausage meat with the cooled onion mixture. If using cheese, fold it in at this stage.
Step 4: Roll out the pastry
Lightly flour your surface and roll out the puff pastry into rectangles. Cut into even strips for uniform rolls.
Step 5: Assemble the rolls
Place a line of filling along one edge of each strip. Roll tightly and seal the edge with a bit of egg wash.
Step 6: Slice and score
Cut into individual rolls and lightly score the tops for a professional look.
Step 7: Apply egg wash
Brush each roll generously to ensure a golden, glossy finish.
Step 8: Bake to perfection
Bake at 200°C (400°F) for 20–25 minutes until puffed, crisp, and beautifully golden.
Step 9: Cool slightly and serve
Let them rest for a few minutes before serving — the filling will be hot and juicy.
