🧅 How to caramelize onions perfectly 🧈

The key to an authentic French onion topping lies in perfectly caramelized onions. This isn’t a step to rush—it’s essential for unlocking the onions’ natural sweetness and complexity.

Steps for perfect caramelized onions:

• Use a wide skillet: More surface area means even browning.

• Melt butter over medium-low heat: Never too hot, or the onions will burn.

• Add onions and stir occasionally: Let them sit undisturbed for several minutes between stirs.

• Cook for at least 20 minutes: True caramelization takes time.

• Add beef broth at the end: Deglazes the pan and brings in the French onion soup vibe.

Avoid overcooking or blackening—the goal is deep golden brown with a soft, jammy texture.
