A delicious recipe for perfectly caramelized onions, enhanced with a touch of balsamic vinegar for added depth.
Heat the butter and olive oil in a large skillet over medium heat.
Using a combination of butter and oil prevents the butter from burning while adding flavor.
Add the sliced onions to the skillet and sprinkle with salt and pepper.
Slice the onions evenly to ensure they cook at the same rate.
Cook the onions, stirring occasionally, until they become soft and translucent.
Keep the heat moderate to avoid burning the onions.
Add the balsamic vinegar and continue cooking, stirring frequently, until the onions are golden brown and caramelized.
The vinegar adds a tangy sweetness that enhances the caramelization.
Serve the caramelized onions warm as a topping or side dish.
These onions are great on burgers, pizzas, or mixed into pasta.
