Ingredients

10 Birchstead British Top Rump Short Rib Cap 95% Beef Burger Pucks (57 g each)
1 pack of Schär Gluten-Free Mini Brioche Sliders (10 × 3 buns).
2 large onions, thinly sliced (red or white)
1-2 tbsp olive oil (or a neutral oil)
1 tbsp butter (optional, for richer flavour)
1-2 tbsp brown sugar (or soft brown sugar)
1-2 tbsp balsamic vinegar (optional, for extra depth)
Salt & freshly ground black pepper
10 small slices of cheese (optional — e.g. mild cheddar, or mozzarella)
Toppings: baby gem lettuce or rocket; slices of gherkin or pickles; tomato slices; mayonnaise, burger sauce, mustard or gluten-free burger sauces of your choice.
A light slather of butter or oil for toasting buns (optional)

Instructions

Caramelise the onions

Heat the olive oil (and butter if using) in a medium sauté pan over medium-low heat.
Add the thinly sliced onions and a pinch of salt. Stir gently.
Add the thinly sliced onions and a pinch of salt. Stir gently.
Add the brown sugar and balsamic vinegar (if using), stir to combine, and cook a further 5 minutes until onions are soft, sweet and jam-like
Remove from heat and set aside.

Cook the burger pucks

Heat a griddle pan or heavy frying pan over medium-high heat. Lightly oil the surface.
Season each beef puck with a little salt and pepper just before cooking.
Place the pucks on the hot pan. For 57 g patties, cook ~2–3 minutes each side for medium-rare/medium; extend by 1–2 minutes per side for well done (adjust to your preference).
If using cheese, add a slice to each puck about 30 seconds before finishing so it melts nicely.
Once cooked, remove from heat and let rest on a plate.

Prepare the buns

Split the gluten-free mini brioche buns and, if you like, lightly butter/toast them on the hot griddle or a clean pan until just crisp & golden — this adds a nice texture contrast.

Serve & enjoy!

Serve warm, ideally with a side of sweet potato fries, a crisp salad, or even a quick slaw
For a pub-style bite: serve 2 sliders per person with a pint or a soft drink; for a snack platter, include assorted sauces and extra toppings so people build their own.

Notes

For a truly restaurant-quality finish, allow the Birchstead beef patties to reach room temperature before cooking — this ensures even browning and maximum juiciness. Gluten-free buns can soften quickly, so lightly toasting the Schär mini brioche sliders adds structure, enhances flavour, and prevents soaking. Take your time caramelising the onions; slow cooking is what develops their deep, sweet flavour and elevates the entire dish. These sliders are best assembled just before serving so the beef stays hot, the cheese remains melted, and the buns retain their soft texture. Perfect for coeliac-friendly entertaining, party platters, pub-style menus or premium takeaway boxes.
