Caramelized Onions

Directions

1. 1
   Peel and trim onions, and vertically slice 1/4 inch thick.
2. 2
   Why? Slicing lengthwise, and not too thinly, maintains the onions' cell structure and keeps them from becoming mushy.
3. 3
   Heat a large nonstick skillet over medium-high heat. Add oil to pan; swirl to coat. Add onions and 1/4 teaspoon salt. Cook 8 minutes, stirring.
4. 4
   Why? A nonstick pan enables long, slow cooking using just a little oil. Beginning over medium-high heat jump-starts caramelization; the salt helps to quickly extract the onions' sugary juices.
5. 5
   Reduce heat to medium-low. Cook for 35 minutes or until deep amber, stirring. Use for pizzas, panini, or pasta tosses.
6. 6
   Why? Milder heat prevents scorching as the onions' natural sugars continue to release and brown. Flavors mellow and the onions shrink and soften.
