French Onion Sausage Rolls

French onion sausage rolls bring together everything I love about party food – that perfect bite of savory pork wrapped in buttery, golden pastry that disappears from the platter before you know it. There’s something about the combination of caramelized onion flavor and flaky layers that just works, whether you’re feeding a crowd on game day or looking for an easy weeknight dinner solution.

I still remember the first time I made these for our church potluck back in the Midwest. I’d been experimenting with my grandmother’s old sausage roll recipe, trying to add a little something extra, when I spotted that packet of French onion soup mix in my pantry. “Why not?” I thought. Well, those rolls didn’t last ten minutes on the table. Folks kept coming back asking what my secret was, and I just smiled. The truth is, it’s not really a secret – it’s about letting good ingredients shine through simple preparation. The French onion seasoning adds this wonderful depth of flavor, almost like you’ve spent hours caramelizing onions, but it comes together in a fraction of the time. My grandchildren now request these every time they visit, and I’ve watched them become the hit of countless gatherings over the years. There’s just something special about pulling a tray of these golden beauties from the oven, watching the steam rise, and seeing everyone’s faces light up. Time to get our hands floury.

I’ve found that these rolls appeal to just about everyone at the table, from picky kids to discerning adults, and they’re substantial enough to satisfy without being too heavy.

Ingredient Spotlight

Pork mince forms the hearty base of your filling and I always choose ground pork with about 15-20% fat content because it keeps the rolls juicy without making them greasy.

French onion soup mix delivers that signature sweet-savory flavor that tastes like you’ve spent hours caramelizing onions, bringing depth and complexity to every bite.

Tomato ketchup adds a subtle sweetness and helps bind the filling together while contributing a touch of acidity that brightens the overall flavor.

Worcestershire sauce brings umami richness to the pork mixture, enhancing the savory notes and adding that hard-to-define depth that makes people ask “what’s in these?”

Dijon mustard provides a gentle tang and slight heat that cuts through the richness of the pork and pastry, creating better flavor balance.

Puff pastry creates those beautiful golden, flaky layers that shatter perfectly when you bite into them, and I prefer using store-bought sheets that have been properly thawed for easier handling.

Egg and milk wash gives your French onion sausage rolls that gorgeous glossy, deep golden finish that makes them look bakery-perfect.

Black pepper adds a gentle warming spice that complements the onion flavor without overwhelming the other seasonings.

How to Make French Onion Sausage Rolls

Step 1. I always start by preheating my oven to 200°C (392°F) and lining a baking tray with parchment paper, which prevents sticking and makes cleanup so much easier.

Step 2. In a large mixing bowl, combine the pork mince, French onion soup mix, ketchup, Worcestershire sauce, Dijon mustard, and cracked black pepper, mixing with your hands or a spoon until everything is evenly distributed throughout.

Step 3. Betty’s tip: Roll out your thawed puff pastry sheets on a lightly floured surface and cut each sheet in half lengthwise to create four long rectangles.

Step 4. I’ve learned that placing a portion of filling along one long edge of each pastry strip works best – use about a quarter of your mixture per strip, shaping it into a log shape.

Step 5. Roll the pastry over the filling snugly but not too tightly, then seal the edges by brushing a little water or egg wash along the seam and pressing gently.

Step 6. After years of making these, I discovered that beating the egg with milk creates a better wash than egg alone – brush it generously over the tops and sides of each roll.

Step 7. The key I discovered is spacing the rolls about an inch apart on your prepared baking tray to allow for even browning and air circulation.

Step 8. Bake for 20-25 minutes, watching for that beautiful golden brown color and checking that the pastry is fully puffed and crisp.

Step 9. My family prefers when I let the French onion sausage rolls rest for about 5 minutes after removing them from the oven, which allows the filling to set slightly and makes slicing cleaner.

Step 10. I’ve found that using a sharp serrated knife to slice the long rolls into individual portions works best, cutting them on a slight diagonal for prettier presentation.

Keeping These Rolls Fresh

I typically store leftover sausage rolls in an airtight container in the refrigerator where they’ll stay fresh for up to 3 days. Betty always lets them cool completely before storing to prevent condensation from making the pastry soggy. When I know I’ll have leftovers, I place a piece of paper towel in the bottom of the container to absorb any moisture.

Betty’s freezing method works wonderfully for these rolls, and I often make double batches specifically for the freezer. I arrange unbaked rolls on a parchment-lined baking tray and freeze them until solid, then transfer them to a freezer-safe bag where they’ll keep for up to 3 months. The beauty of this approach is you can bake them straight from frozen – just add an extra 5-7 minutes to the cooking time and they come out perfectly golden.

For the best texture, I reheat refrigerated rolls in a preheated 180°C (350°F) oven for about 8-10 minutes until warmed through and the pastry crisps up again. Through trial and error, I learned that microwaving makes the pastry soft and chewy rather than flaky, so I only use that method when I’m really pressed for time. Betty always says that good pastry deserves proper reheating.

Perfect Partners for This Recipe

Honey mustard or whole grain mustard dipping sauce complements the savory onion flavors beautifully and adds a tangy kick that my family always requests. For another delicious dipping option, try pairing these with the creamy garlic sauce from my cheesy garlic chicken wraps.

Fresh garden salad with vinaigrette provides a crisp, refreshing contrast to the rich, buttery pastry and helps balance the meal with bright acidity and crunchy greens.

Roasted vegetable medley with carrots, bell peppers, and zucchini brings color to the plate while offering a healthier side that doesn’t compete with the main attraction.

Simple coleslaw adds crunch and a touch of sweetness that works wonderfully alongside the French onion sausage rolls, especially at summer gatherings.

Tomato soup or French onion soup creates a comforting, cohesive meal when you’re serving these rolls as a main course on chilly evenings. If you’re looking for another cozy soup pairing, my chicken pot pie soup makes a wonderful companion.

Pickles and olives provide that briny, sharp element that cuts through richness, and I always include them on my appetizer spreads.

If you’re planning a party spread, these sausage rolls pair beautifully with other finger foods like mozzarella pepperoni croissant rolls and pepperoni pizza bombs.

Tips for Best Results

Use fresh, high-quality pork mince with 15-20% fat content for juicy filling that stays moist during baking without becoming greasy.

Distribute filling evenly along each pastry strip to prevent uneven baking and leakage – less is often more when it comes to the amount.

Brush egg wash lightly but thoroughly for consistent golden crust across all your rolls, making sure to cover the sides as well as the tops.

Enjoy fresh for maximum flakiness or reheat properly in the oven to restore that crispy texture we all love.

Try adding chopped herbs like thyme or parsley to the filling for extra flavor dimension and a touch of freshness.
