These beef sliders with provolone and balsamic onions offer a sophisticated twist on a classic high-protein favourite. By using quality minced beef and sharp provolone piccante, you create a depth of flavour that far surpasses a standard burger. The secret lies in the quick-pickled balsamic onions, which provide a bright, acidic crunch to cut through the richness of the melted cheese and savoury meat.
Perfect for casual entertaining or a weekend treat, these mini burgers are designed to be shared. They fit seamlessly into a high-protein diet while remaining a crowd-pleasing option for guests. For the best results, serve them in soft potato buns with a generous dollop of creamy aioli to bring all the Mediterranean-inspired elements together.

Ingredients for Beef Sliders with Provolone and Balsamic Onions
900g beef mince (20% fat)
Kosher salt, freshly ground pepper
4 slices provolone piccante cheese, torn in half
8 potato slider buns
1 large red onion, very thinly sliced into rounds
3 tablespoons balsamic vinegar
1 teaspoon sugar
Aioli or store-bought mayonnaise (for serving)
How to make Beef Sliders with Provolone and Balsamic Onions
Back to contentsDivide meat into 8 portions (about 110g each). Place 1 portion on a work surface. Cup your hands around the meat and shape it into a rounded mound. Gently flatten patty to about 3/4" thick. Season both sides with salt and pepper. Repeat with remaining portions of meat.
Prepare a grill for medium-high heat. Grill patties until lightly charred on bottom, about 3 minutes. Flip and top with a piece of cheese. Grill to desired doneness (cheese should be melted), about 3 minutes for medium-rare. Transfer patties to a cutting board and let rest 5 minutes.
While patties are resting, grill the buns, cut side down, until lightly charred around the edges, about 30 seconds.
Toss onion with vinegar, sugar, and a pinch of salt in a medium bowl and let sit, squeezing onions occasionally to soften slightly, 5 minutes.
Build sliders with patties, buns, onions, and aioli.
Patties can be formed 6 hours ahead. Cover and chill.
