Garlic: Fresh garlic cloves add depth; don’t skimp on this aromatic wonder!

For the Egg Wash:
Eggs: You’ll need one egg mixed with a splash of water to create that beautiful golden finish.

How to Make French Onion Sausage Rolls
Sauté the Onions: Start by heating olive oil in a skillet over medium heat. Add thinly sliced onions and cook until they turn translucent and begin to caramelize—about 15 minutes. Stir occasionally so they don’t burn!
Add Garlic and Sausage: Toss minced garlic into the skillet alongside crumbled Italian sausage. Cook everything together until the sausage browns and releases its savory aroma—around 8 minutes should do it!
Incorporate Cheese and Seasoning: Once your sausage is browned, stir in grated Gruyere cheese until it melts into gooey goodness. Season with salt and pepper to taste; trust me, your taste buds will thank you.
Prepare Puff Pastry Sheets: Roll out your thawed puff pastry sheets onto a lightly floured surface. Cut them into rectangles large enough to wrap around your filling—about 4 inches by 6 inches works perfectly.
Fill and Seal the Rolls: Place a generous spoonful of your delicious sausage mixture onto one half of each pastry rectangle. Fold over the other half and seal edges with a fork; this ensures no cheesy goodness escapes during baking.
Bake Until Golden Brown: Preheat your oven to 400°F (200°C). Brush each roll with egg wash for that shiny finish before placing them on a lined baking sheet. Bake for about 20-25 minutes until golden brown and flaky.
Now that you know how to create these mouthwatering French Onion Sausage Rolls, it’s time to gather your loved ones around the table—or couch—and dig in!
