Ingredients:
- 1 lb (450 g) ground beef (ideally 80% lean for juiciness)
- 1 tsp dried oregano
- 1 tsp dried basil
- ½ tsp garlic powder
- ½ tsp onion powder
- ½ tsp salt
- ¼ tsp black pepper
- ½ cup (120 g) mayonnaise (preferably homemade or good-quality store-bought)
- 1 tbsp balsamic vinegar
- 1 garlic clove, minced
- Salt and pepper to taste
- 4 ciabatta rolls (or similar rustic Italian bread)
- 4 slices provolone cheese
- 4 slices mozzarella cheese (fresh if possible)
- ½ cup (75 g) sun-dried tomatoes (preferably oil-packed, drained and roughly chopped)
- 1 cup (25 g) fresh basil leaves
- 1 tbsp olive oil (for toasting buns)
Instructions:
- Combine mayonnaise, balsamic vinegar, and minced garlic in a small bowl. Whisk until smooth. Season with salt and pepper to taste. Refrigerate until ready to use.
- In a large bowl, combine ground beef with oregano, basil, garlic powder, onion powder, salt, and black pepper. Mix gently to combine; avoid over-mixing for tender patties. Shape into 4 even patties, about ¾ inch (2 cm) thick.
- Heat grill pan or skillet over medium-high heat. Cook patties for 4-5 minutes per side, or until internal temperature reaches 160°F (71°C) for well-done. Place a slice each of provolone and mozzarella cheese on top of patties in the last minute to melt.
- Slice ciabatta rolls horizontally. Brush cut sides lightly with olive oil. Toast in a separate pan or under a grill until golden brown.
- Spread a generous layer of balsamic aioli on the bottom bun. Place the cheeseburger patty on top. Add chopped sun-dried tomatoes and fresh basil leaves. Cap with the toasted top bun.
- Serve hot with your choice of sides.
