Instructions

Caramelise the onions

  • In a pan, heat olive oil and cook the sliced onions on low heat for 15–20 mins until soft, golden, and sweet.

Make the sliders

  • Season the beef mince with salt & pepper, shape into 10 mini patties, and pan-fry or grill for 3–4 mins per side until cooked through.

Garlic butter

  • Melt butter with minced garlic, gently simmer for 1 min.

Assemble

  • Split each brioche bun, brush with garlic butter, and lightly toast. Spread mayo and mustard, add patties, cheese, caramelised onions, and top with the golden brioche lid.

Finish & serve

  • Garnish with fresh parsley and serve warm.

Notes

Buns: St Pierre Mini Brioche Buns are naturally rich and buttery – lightly toasting them with garlic butter makes them extra indulgent.
Meat Swap: You can replace beef with chicken, turkey, or even plant-based mince for a lighter or vegetarian-friendly version.
Cheese Options: Cheddar, gouda, or Swiss cheese melt beautifully – pick your favourite!
Caramelised Onions: Low and slow cooking is key – resist the urge to rush for the best sweet, golden finish.
Make Ahead: Patties and caramelised onions can be prepped the day before; just reheat and assemble when ready to serve.
Serving Size: Great for party platters, appetisers, or fun family dinners – they disappear fast!
Pairings: Delicious with sweet potato fries, rocket salad, or a side of coleslaw.
Chef’s Tips
Perfectly Juicy Patties: Gently shape the mince into patties without overworking – this keeps them tender. Press a small dent in the centre of each patty before cooking to prevent them puffing up.
Extra Flavour Boost: Mix a dash of Worcestershire sauce or smoked paprika into your mince for a richer depth of flavour.
Crisp Finish: After caramelising, deglaze the onion pan with a splash of balsamic vinegar or red wine for tangy-sweet onions.
Golden Brioche: Brush the cut sides of the buns with garlic butter before toasting for a glossy, golden crunch.
Keep it Warm: If making a batch, keep sliders warm in a low oven (around 100°C) before serving so the cheese stays melty.
Plating Tip: Serve on a wooden board with cocktail sticks to hold them together – practical and Instagram-worthy!

Gluten-Free & Vegan Alternatives

Nobody should miss out on these delicious sliders, and with a couple of smart swaps, you can enjoy them gluten-free or fully plant-based without compromising on taste.

Gluten-Free Option – with Schar Gluten Free Mini Brioche Sliders 10×3

If you’re catering for coeliac diets or anyone avoiding gluten, Schar’s brioche sliders are the perfect alternative. Soft, golden, and slightly sweet, they mimic the flavour and texture of traditional brioche while being 100% gluten-free. Pair them with juicy patties, caramelised onions, and garlic butter for sliders everyone can enjoy.

Tip: Lightly toast gluten-free brioche to hold the fillings better and avoid sogginess.

Vegan Option – with La Boulangerie Vegan Brioche Style Burger Bun

For a plant-based version, swap to La Boulangerie’s Vegan Brioche Style Buns. Rich, soft, and golden, they deliver the same indulgence as classic brioche but are made without eggs or dairy.

Patties: Use your favourite plant-based burger or make lentil/bean patties.

Cheese: Melt vegan cheddar or smoky vegan cheese for the perfect bite.

Butter: Replace garlic butter with a dairy-free spread for that same garlicky kick.

Sauce: Keep it creamy with vegan mayonnaise.

Result: A fully plant-based slider that’s every bit as indulgent as the original – glossy buns, savoury filling, caramelised onion sweetness, and garlicky richness in every bite.

With St Pierre, Schar, and La Boulangerie, Nicol Retailer offers a brioche option for everyone — traditional, gluten-free, and vegan — so no guest is left out at your table.
