The Secret to Perfect Caramelized Onions
Many home cooks hesitate at caramelizing onions because it takes time, but it’s absolutely worth it. Here’s a chef-approved method:
- Slice Uniformly – Cut onions into even ¼-inch slices so they cook evenly
- Low and Slow – Keep the heat at medium-low to prevent burning
- Don’t Stir Too Much – Let them sit for 3-4 minutes between stirs to develop color
- Deglaze Smartly – If onions stick, add a splash of water or wine to lift the flavorful bits
For an extra flavor boost, try:
- Adding a sprig of rosemary while caramelizing
- Using a mix of yellow and red onions
- Finishing with a drizzle of balsamic glaze
