Cooking Instructions

Follow these simple steps to prepare this delicious French Onion Sausage Rolls:

Step 1: Preheat Your Oven

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup later; nobody wants a messy kitchen!

Step 2: Sauté Those Onions

In a skillet over medium heat, melt some butter and add sliced onions. Stir occasionally until they turn golden brown and caramelized—this usually takes about 15-20 minutes. Add minced garlic during the last few minutes to release its aroma.

Step 3: Brown the Sausage

In another pan, cook the ground sausage over medium heat until browned. Break it apart with a spatula so it cooks evenly. Mix in salt and pepper to bring out its flavor.

Step 4: Combine Ingredients

Once both the onions and sausage are cooked, combine them in one bowl. Add shredded cheese and mix well until everything is evenly distributed.

Step 5: Assemble Your Rolls

Roll out the puff pastry sheets on a floured surface. Cut them into rectangles, spoon some filling onto one half of each rectangle, then fold over to seal. Crimp edges with a fork for that artisanal look.

Step 6: Egg Wash & Bake

Brush each roll with egg wash using a pastry brush. Place them on your prepared baking sheet and bake for about 25-30 minutes or until golden brown.

Transfer to plates and serve warm for the perfect finishing touch! These French Onion Sausage Rolls are sure to become a hit at any gathering—or perhaps just at home when you can’t resist sneaking one (or five) straight from the oven!
