Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor without any fuss. Here’s what you’ll need:

• For the filling:
  • 1 pound (450g) sausage meat (use your favorite blend—pork, chicken, or turkey works great!)
  • 1 large onion, finely sliced
  • 1 tablespoon unsalted butter (for caramelizing the onions)
  • 1 teaspoon olive oil (to prevent the butter from burning)
  • 1 teaspoon dried thyme (or fresh thyme for extra flavor)
  • 1 teaspoon Worcestershire sauce (adds depth and umami)
  • Salt and pepper, to taste
• For the pastry:
  • 1 sheet of puff pastry, thawed (store-bought works perfectly!)
  • 1 egg, beaten (for egg wash)

If you’re looking for substitutions, you can use ground chicken or turkey instead of pork sausage. For a vegetarian twist, try using a plant-based sausage alternative!

Equipment Needed

You don’t need much to make these delicious sausage rolls, but here’s what will come in handy:

• Sharp knife: For slicing the onions and trimming the pastry.
• Nonstick skillet: Perfect for caramelizing onions without sticking.
• Mixing bowl: To combine your filling ingredients.
• Baking sheet: Lined with parchment paper to prevent sticking.
• Pastry brush: For applying the egg wash.

If you don’t have a pastry brush, you can use the back of a spoon to spread the egg wash. And if you’re out of parchment paper, a lightly greased baking sheet will do the trick!

Preparation Method

1. Caramelize the onions: Heat the butter and olive oil in a skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for about 20 minutes, or until golden and caramelized. Stir in the dried thyme, Worcestershire sauce, and a pinch of salt and pepper. Let cool.
2. Prepare the filling: In a mixing bowl, combine the sausage meat with the cooled caramelized onions. Mix thoroughly using a spoon or clean hands.
3. Roll out the pastry: On a lightly floured surface, roll out the puff pastry to smooth any creases. Cut it into two long rectangles.
4. Fill and roll: Divide the sausage mixture into two portions. Place each portion in a log shape along one edge of the pastry rectangles. Roll the pastry tightly around the filling, sealing the edges with a little beaten egg.
5. Slice and brush: Cut each roll into smaller pieces, about 2-3 inches long. Place them seam-side down on a parchment-lined baking sheet. Brush the tops with beaten egg for a beautiful golden finish.
6. Bake: Preheat your oven to 375°F (190°C). Bake for 25-30 minutes, or until the pastry is golden and cooked through.

Your kitchen will smell incredible as these bake, so be prepared for hungry family members hovering around the oven!

Cooking Tips & Techniques

• Don’t rush the onions: Caramelizing onions takes time, but it’s worth it! Low and slow is the way to go.
• Seal the pastry well: Use the egg wash to seal the edges; this prevents the filling from escaping during baking.
• Keep the pastry cold: If your puff pastry gets too warm while working with it, pop it back into the fridge for 10 minutes.
• Test for doneness: The sausage filling should be fully cooked—check with a meat thermometer if needed (it should reach 160°F/71°C).

Variations & Adaptations

• Vegetarian Option: Use plant-based sausage and add a touch of grated cheese to the filling for extra richness.
• Seasonal Twist: Swap caramelized onions for sautéed mushrooms or roasted peppers during summer months.
• Spicy Kick: Add a pinch of chili flakes or hot paprika to the sausage mixture for some heat.

Personally, I’ve tried adding a sprinkle of grated Gruyère cheese to the filling—it’s a game-changer for cheese lovers!

Serving & Storage Suggestions

These sausage rolls are best served warm, straight out of the oven, but they’re just as delicious at room temperature. Pair them with a tangy mustard dip or a side of marinara sauce for dipping.

Storage: Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, pop them in a 350°F (175°C) oven for 10 minutes or until warmed through. You can also freeze unbaked rolls and bake them straight from frozen—just add 5-10 minutes to the baking time.

FAQs

Can I use store-bought caramelized onions?

Yes, store-bought caramelized onions can save time, but homemade ones taste better and are worth the effort!

Can I make the rolls ahead of time?

Absolutely! Assemble them, store in the fridge, and bake when ready. You can also freeze them unbaked for up to 1 month.

What dipping sauces go well with these rolls?

Mustard, marinara, or even a honey mustard dip pair wonderfully with the savory filling.

Can I use phyllo pastry instead of puff pastry?

Yes, but the texture will be different. Phyllo pastry creates a lighter, crispier result.

How do I prevent the filling from spilling out?

Seal the edges of the pastry tightly with egg wash and ensure the rolls are placed seam-side down on the baking sheet.
