How to Make the Best Flying Dutchman Burger Onion Buns

Instead of regular burger buns, caramelized onion buns are a tasty and low-carb option. They give the Flying Dutchman a smoky taste, natural sweetness, and a rich texture that goes great with it. If you want to make caramel, big yellow onions are best because they hold their shape better while cooking.

Step-By-Step Preparation

Step 1

  • Onion Preparation:
  • Peel the big yellow onions and cut them into thick pieces that are about half an inch thick. You need thick onion rounds so they stay hard enough to use as burger onion buns.
    Brush olive oil on both sides, then add salt, black pepper, and a pinch of sugar to taste. The sugar highlights the onions’ inherent sweetness and darkens the caramelization.

Step 2

  • Cooking of Onion:
  • Add a little olive oil to a skillet or cast iron pan and heat it over medium-low heat. Carefully add the onion rounds to the pan and simmer for a few minutes.If you flip the onions too often, the layers can split and fall apart. If the onions start to dry out before they get soft, add a little water and cover the pan for a short time. This will help them cook evenly.

Step 3

  • How to Get the Ideal Caramelization:
  • For another 20 to 30 minutes, keep cooking the onions slowly until they are soft, golden brown, and just a little crispy around the edges. When caramelized just right, the onion-wrapped burger gets its signature smoky flavor and rich sweetness.
    Once the onions are fully browned, take the buns out of the pan and let them cool a bit before putting together your burger.
