Savory French Onion Sausage Rolls – Golden, Flaky & Full of Flavor

Savory French Onion Sausage Rolls are the kind of food that disappears fast. From the first bite, you get flaky pastry, juicy sausage, and sweet caramelized onions all working together. This recipe takes the deep, cozy flavor of French onion soup and turns it into a handheld, crowd-pleasing snack.

If you love classic sausage rolls but want something more flavorful, this is the upgrade. The onions are cooked slowly until golden and soft. That slow cooking brings out sweetness and richness without needing fancy ingredients. Combined with well-seasoned sausage meat and wrapped in puff pastry, the result feels indulgent but familiar.

Savory French Onion Sausage Rolls work for many moments. Serve them as party food, game-day snacks, or even a relaxed dinner with a salad. They feel special enough for guests but easy enough for a weekend bake.

I like this recipe because it balances effort and reward. The onions take time, but they do most of the flavor work for you. Once they are ready, everything else moves quickly. You can prep ahead, freeze extras, or bake fresh when needed.

Ingredient Notes

• Sausage Meat
  Use good-quality pork sausage meat. It carries the flavor and stays juicy. Beef or chicken sausage also works.

• Onions
  Yellow onions are best for caramelizing. Slice them thin for even cooking.

• Butter and Olive Oil
  Using both adds flavor and prevents burning during long cooking.

• Garlic
  Adds depth but should not overpower the onion sweetness.

• Thyme
  Classic with onion flavors. Fresh is best, dried works too.

• Puff Pastry
  Store-bought puff pastry saves time and bakes evenly.

• Egg
  Used for egg wash to get that golden finish.

Special equipment needed: skillet, baking tray, parchment paper

How To Make Savory French Onion Sausage Rolls

1. Caramelize the Onions

Heat 1 tablespoon butter and 1 tablespoon olive oil over medium-low heat.
Add 2 large sliced onions with a pinch of salt.

Cook for 20–25 minutes, stirring often.
Look for soft, deep golden onions (not browned too fast).

2. Add Garlic and Herbs

Add 2 cloves minced garlic and 1 teaspoon thyme.
Cook for 1 minute until fragrant.

Remove from heat and cool fully (hot onions soften pastry).

3. Prepare the Filling

In a bowl, mix 500 g sausage meat with cooled onions.
Season lightly with black pepper (taste sausage first).

4. Prepare the Pastry

Preheat oven to 200°C (400°F).
Roll puff pastry into a rectangle and cut lengthwise.

5. Fill and Roll

Place filling down the center of each strip.
Roll tightly and seal edges underneath.

6. Egg Wash and Slice

Brush with beaten egg.
Slice into even rolls using a sharp knife.

7. Bake

Bake for 25–30 minutes until puffed and golden.
Rest 5 minutes before serving.
