INGREDIENTS
1 sweet potato 1 onion 2 tbsp red wine (optional) Arugula ̈Burger buns
METHOD
Heat oven to 390°F.
Cut the sweet potato in half or in small pieces and bake until tender (for 30-40 min).
Slice the onions into thick slices. In a saucepan, heat olive oil over medium-low heat. Add sliced onions and stir.
Let them cook for 10 minutes and add red wine (optional). Cook for another 10 minutes or so, stirring occasionally until the onions caramelize.
Prepare your burger with mashed sweet potato, caramelized onions and arugula.
The recipe quietly relies on starch retrogradation in cooled sweet potato, which subtly firms the patty—without this, the burger risks collapsing despite perfect caramelization. Time Duration Calculator
