Caramelized melting onions are a delightful addition to any meal, offering a unique combination of sweetness and tenderness. This dish captures the essence of slow-cooked onions, transforming them into a rich, golden accompaniment that's perfect for both simple weeknight dinners and special occasions. The process of caramelizing onions requires patience, as it involves slowly coaxing out the natural sugars to develop a deep, sweet flavour. The result is a velvety texture that pairs beautifully with a variety of dishes, from roasted meats to hearty grains.

Instructions

Prepare the onions

Peel the onions and slice them into thick rounds, approximately 1.5 cm (1/2 inch) thick.

Pro tip: Use sweet onions for a milder, sweeter flavour.

Heat the pan

In a large skillet over medium heat, melt the butter with the olive oil.

Add onions to the pan

Arrange the onion slices in a single layer in the skillet. Sprinkle with salt and pepper.

Pro tip: Avoid overcrowding the pan to ensure even cooking.

Begin caramelizing

Cook the onions untouched for about 10 minutes until they start to brown on the bottom.

Pro tip: Resist the urge to stir them too soon.

Flip and continue cooking

Carefully flip the onions and lower the heat to medium-low. Cook for another 30-35 minutes, flipping occasionally, until they are deeply golden and tender.

Pro tip: Add a splash of water if the onions start to stick.

Deglaze and finish

Add balsamic vinegar and stir to deglaze the pan, scraping up any browned bits. Cook for another 2-3 minutes.

Pro tip: The balsamic vinegar adds a nice tangy sweetness.
